"What sound?" In the darkness of dawn, Cao Ren, who was standing at the top of the city, heard the rumbling sound, and immediately turned his head and asked Le Jin.

When Le Jin heard this rumbling sound, his first reaction was that Osven could no longer bear it and used the Sun Knight to attack the city, but the next moment, Cao Ren and Le Jin denied this idea. Osven was not a fool, so how could he do this?

Not to mention the darkest time before dawn, when the Sun Knights Legion was the weakest, just the idiot behavior of cavalry siege, there would be no normal generals to do it.

"Can it be?" Le Jin turned his head and looked at Cao Ren and asked.

"It should be a dam breaking!" Cao Ren nodded, "Let everyone go up to the city wall and prepare to survive the last wave. I originally thought Osven would have the patience to fight us here and then use the flood to fight against the lord, but I didn't expect that the other party would use it directly at this time."

Cao Ren, Le Jin and others were on guard against the Kushan dike from the beginning. In fact, the biggest hidden danger of this battle was that Osven broke the dike and flooded the Cao army's fortress downstream.

It is obvious that after three days and nights of fierce attacks, Osven confirmed that the Han army had entered a period of fatigue and decisively excavated the simple embankment that he had arranged in the upper reaches of the Helmand River.

The surging flood hit the fortress guarded by Cao Ren. Even if there was a problem of insufficient water, the fortress built in the upper reaches of the Helmand River was greatly affected. This was the opportunity Osven was waiting for, and this was also the reason why Osven must take advantage of the dawn.

After all, Cao Ren and others are not fools. If Osven suddenly retreated in broad daylight, they would be more or less prepared. However, after three days of fierce attack, even Cao Ren would be negligent when adjusting and breathing.

These negligence and dullness are the opportunities that Osven wants to fight for. The surging floods rushed towards the fortress guarded by Cao Ren.

Unfortunately, this fortress was prepared for water and fire as early as when Xun Yu was building it, and coupled with insufficient runoff from the Helmand River, this impact was not enough to disintegrate Cao Ren's fighting spirit. The flood was about to completely destroy this fortress.

However, Cao Ren knew very well that since Osven prepared the flood, the other party must have prepared the ship, which was the biggest problem.

Not to mention the Sun Knight, the scimitar assaulters led by Salman are actually not inferior to Le Jin and Cao Ren's headquarters. Most of the reason why they were unable to take the fortress before was that they could not rush up to the city wall on a large scale. Now that the flood is coming, it is only a matter of time before Osven and others board the city wall on a boat. Who made most of the river channels in the valley block?

By the later period of flood discharge, Osven may not be able to climb the city wall by relying on the flood, but now, the flood is only one or two meters lower than the city wall.

If it weren't for the influence of mountains here, the warm and humid air currents of the Indian Ocean could not go north, resulting in the rocks on the north side without those century-old giant trees. Otherwise, the giant trees would be cut down and thrown into the flood, and the city would be attacked by gravity potential energy, and the Han army fortress would not be able to defend it no matter what.

However, if a hundred-year-old giant tree could grow here, the ecological environment would not be so terrible, and it would not be called an imperial cemetery or something.

"Let Mancheng not take action first. Be prepared with me. It depends on this wave if you can defend the fortress." Cao Ren ordered Le Jin very solemnly.

After escorting this wave, Osven would not be able to continue attacking the fortress, because it would take several days for the flood to recede, and after the retreat, the remaining mud would not be cleaned up in a short time, which led to the fact that Kushan would not be able to attack the fortress for at least ten days.

For a famous general like Cao Ren, after enduring the most difficult period, he had another ten days of rest. All the advantages Osven had accumulated with hard work before were gone, which was equivalent to starting over, so the next step is very important.

Le Jin also understood this, so he nodded and gathered all his soldiers under his command. At this time, the surging flood was blocked by the fortress and had obviously accumulated. The waves behind him became bigger and bigger. When the morning glow appeared, the flood slapped on the city wall and could even splash onto the top of the city.

At this time, almost sewage flowed in the fortress. Even if Li Dian kept organizing his soldiers to block the city gate, sewage would inevitably penetrate in the end. When Chaoyang appeared in the east, the flood in the fortress had already submerged to its thighs.

Fortunately, Cao Ren ordered a large amount of fried noodles to be made early, and large water jars were also stored on the city walls and in the higher places in the city. After all, when the city was built, it was ready to deal with floods, and now these preparations have been used.

When the water level slowed down slightly, about one meter away from the city wall, Osven and others appeared upstream with ships and vehicles that had been prepared.

This time was the time calculated by Osven. After all, he knew that it seemed unrealistic to directly destroy the fortress of the Han Dynasty, but he didn't need to destroy it. He just needed to rush to the top of the city.

"Cao Ren, surrender!" Salman's evaluation of Cao Ren is not low, because he knows very well that if he doesn't rely on floods, he really has to grind it slowly to win this city, and even if he grinds like this, he may not be able to win it. Thinking of this, Salman couldn't help but sigh that the Han Dynasty is so talented, even an unknown person, has such ability.

Cao Ren looked at Salman from afar, ready to fight with all his might. He didn't expect the other party to say such funny words, and he couldn't help but show a look of ridicule.

"Surrender?" Cao Ren looked at Salman with a sarcastic look on his face, "Are you worthy?"

"You can't stop it. Your skill in defending the city is indeed good, but when we rush forward, you can't stop it. Not only can you stop it, but the soldiers behind you can't stop it either." Salman said seriously, "And your food and grass have also been destroyed by the flood. We have fought with you so many times. We know very well that your granaries are usually underground."

Because he was still upstream, it would take some time for Salman to come, so he greeted Cao Ren directly from a distance in the valley, with many tricks in his words.

"Hahaha!" Cao Ren laughed. My leader had been frying fried flour for three days, and I wanted to see who couldn't hold on first.

"It's stubborn!" Salman said with a sneer.

"Shoot the arrow!" Cao Ren ordered coldly, "Whatever you want to pretend, just do it. If you can kill it, you will take it away. If you can't kill it, it will be useless if you say anything!

The arrow rain covered the opposite side with dense rain of arrows. The Han army and Kushan simultaneously displayed their own long-range suppression capabilities. At the same time, the Kushan boat flew towards the Han army's fortress like an arrow from a string. It had been moving slowly before, but it was rowing in reverse, but now it was going down the water, rowing with all its strength, and its speed suddenly exploded.

The super high quality even made the first half of the boat go directly out of the water and flew towards the fortress. In groups of eighteen people, they rushed over on a large scale, even when they were about to hit the city wall, they had no intention of stopping the boat.

This kind of bandit-like behavior made Cao Ren stunned. Are these lunatics really not afraid of death? The fortress is so wide that if it hits the top of the city, throws the members on the boat out, fly directly over the city wall, and falls down, then suddenly dies on the spot.

In fact, it is not that they are not afraid of death, but that even the soldiers on Beigui, even carefully selected boatmen, would not be able to stop the ship at such a high speed.

To be precise, after using this flood, Osven realized that he had actually had a little capsized, because most of the people in the mountains in Beigui had never seen the flood and had never rowed the boat. They were just a little confused when they boarded the boat.

If it weren't for the fact that there were a group of backbone soldiers Osven brought from the south, and with this plan, Osven would have found that he had bought more than ten days for his opponent.

From this point of view, Osven is indeed a bit lacking in strategy. He feels too heavy when he cares about his head and tail. Salman actually didn't expect this problem. The reason why his soldiers under him looked stupid this time was that even the so-called scimitar who had played with water was confused after getting on the boat and rushing wildly.

This is also the reason why more than a dozen boats did not stop the ship and directly hit the city wall. More than a hundred people flew from the boats to the top of the city, or even flew over the city wall.

After all, when you walk smoothly, your speed can reach a very outrageous level. As an ordinary Northern Gui soldiers, you don’t have the experience of soaking out of the water in Jiangdong soldiers, and you don’t know how to exert force on the ship at all.

The boat did not capsize, more because the boaters were all experienced southerners...

This scene was very exciting. In Salman's opinion, it was an operational error, but in the Han army's opinion, it was this group of people who decided to fight quickly. So after the scimitar assaulter flew from the boat to the city wall, the battle between the Han army and the Kushan began directly.

Compared to the way of siege that was previously relying on cloud ladders and flying bridges, which could only rush up to a few or even dozens of people at a time, this time, Kushan climbed up hundreds of soldiers in one breath, and then a steady stream of soldiers rushed up to the boats.

Of course, there are also many elite Beigui who have stepped on the air and fell into the water and disappeared directly. After all, the people here are like the inland people in the Han Dynasty. Most of them can't swim, unless they are close to a big river or have a relatively large lake in their residence.

However, even so, the pressure of the Han army increased suddenly. After all, Salman's scimitar assaulter is stronger, and Salman's legion itself is suitable for breaking through the front line. Heavy scimitars can directly cut out a pale arc blade with one stroke out of thin air. This method of near-range attack is inevitable that even the Han army will be a little difficult to deal with.

The reason why they could easily suppress it was more because the opponent had few people and could use long spears to suppress it in the medium and short range. But now the soldiers of Beigui are constantly rushing up, and the front line of the Han army is obviously much more embarrassing. Moreover, the biggest problem in the offensive and defensive battle in the city wall is that there is too little room for maneuver, which is easy to occur. If you take a few steps, you will not be able to retreat.

So much so that in the face of this brutal chopping and killing attack, Cao Ren and Le Jin's subordinates were inevitably embarrassed. After all, the group of soldiers who flew directly from the top of the city over the city wall and fell into the city because of the brutal attack. At this time, they rushed up from the inner city and tried to attack the Han Dynasty together.

"Continue to rush, don't be afraid. Fly over the top of the city. There is four feet deep water inside, and you can't die if you fall." Beigui's soldiers, covered in water, rushed up and roared at their comrades.

Because of the flood infiltration, the city was only thigh-deep in its trunk, but now it is about 1.23 meters long. This water depth is enough for most soldiers to fall off the city wall, then choke a few mouthfuls of water, climb up to continue fighting.

"No!" Cao Ren's face turned pale. He had never expected that Kushan's previous behavior would have such a deep plan. He immediately did not dare to have any reservations and directly activated his legion talent. He saw layers of golden luster appearing on the bricks on the city wall, covering all Cao Ren's command.

"Form a formation to deal with it!" Fighting hard will only suffer, especially when Kushan hit the wall wildly, people kept flying into the city, then got up from the water in the inner city, rushed up quickly to the city wall, and attacked the Han army. Cao Ren did not dare to delay.

The light golden glow appeared on the Han soldiers like a barrier. It had no other special effect, it was pure defensive power, a manifestation of the city wall's defense ability, and a manifestation of Cao Ren's army's talent.

The pale arc light cut on the layer of light golden translucent glow, bringing up a piece of fine golden sand, but it did not directly hurt the soldiers of the Han army like before, and the scratch that was even worse was constantly recovering.

This is Cao Ren's legion talent, a talent that can only be used near the city. Its ability is also very reliable, pure defense, but unlike other defenses that are destroyed if they are blown up, this thing is cut and can be restored by itself as long as the city wall is not broken. To a certain extent, it is a thing close to idealistic defense.

By the way, this thing has a strong defense, roughly equivalent to the defense brought by the stone used for building a city, and it has a certain resistance to all types of strikes. The only disadvantage is that the further away from the city, the smaller the strengthening.

In the past, due to the situation in the Han Dynasty, Cao Ren's talent was not available at all. This time it was the first time that he used it formally.

As the defensive strength of Jiancheng Stone, its ability to fight slash is not very strong, but the thickness of Jiancheng Stone is often longer than the weapon itself.

In this way, the performance of this legion's talent reflected in Cao Ren's legion became. Salman's scimitar slashed with a knife, and the arc light cut out a lot of golden debris, and then the force dissipated and ended, leaving behind a gradually recovering golden light wall.

Cao Ren is actually not afraid of sharp attacks on the city wall. Unless it is an extraordinary level, there is no way. If you can really cut through the standard stone for building this city wall at one stroke, you can only solve the problem by relying on attack speed.

This is also the reason why Cao Ren generally did not bring shield guards later, because his talent itself was very similar to the situation of shield guards, and he could withstand a sharp attack by himself. However, he would suffer from the talent of heavy weapons attacks and shield guards. So later Cao Ren felt that the army he should lead the most was light infantry with high attack speed and high killing.

Simply put, Cao Ren wanted to lead Ruiz, but later found that Ruiz took action and directly penetrated his legion talent from the inside...

That's right, the second shortcoming of Cao Ren's talent is that talent itself is equivalent to the actual stone for building a city. If you take action from the inside, you will be blocked. This leads to Cao Ren being able to use a relatively normal legion, fighting to the death while fighting.

However, Cao Ren has a clear positioning of himself. He is a general who defends the city, so he can just bear it. If he really can't beat him, he will just stand in line to keep it. He can't get the city and be forced to give up. Even if he will be beaten very much, then so what!

Le Jin also exuded his own legion talent. After so many years of adjustments and the influence of the immortal slaying Taoism, Le Jin can be regarded as being able to exert his own legion talent to interfere with reality, allowing soldiers to feel their own mental and mental abilities.

Although there is no way to exert his extraordinary ability like Guan Yu, his normal level of performance is enough to allow Le Jin Legion to quickly exert a considerable combat effectiveness.

"General Zixiao, you defend the rear, I will fight back!" Le Jin shouted loudly at Cao Ren. If you have to defend for a long time, you will lose. Moreover, Le Jin himself is not good at defense, so after the Beigui Legion climbed the city wall on a large scale, he directly chose to open up the army's talents and fight Salman to the death!

The light blue luster bloomed directly from Le Jin's body. The subordinates all felt Le Jin's beliefs, and the interference in will was directly displayed on individuals. Even if the difficulty of will interfering with reality increases significantly after the change of heaven, Le Jin's legion talent is still pure, which means that Le Jin can still interfere with reality!

"Die!" Le Jin led his personal guards to rush towards Salman with a gun. At the same time, Salman did not dare to keep any reservations and fully unfolded his own mental image.

Originally slashed out from the scimitar, it could only last for a few seconds. When it was thrown out from the blade, the maintenance time exceeded one second. This little time gap directly caused the attack range and attack intensity of the scimitar assaulter to explode.

This is the continuation of the mind symbols developed and expanded by Salman in the past decade. The intensity of this mind symbol is not very high, but Salman devotes almost all the power of the mind symbol to the continuation aspect.

The continuation of blade light, the continuation of wind, the continuation of empty cuts, and the continuation of very, very important muscle strength. Although Salman wanted to continuate his life, he finally found that his mental image could be developed, but in just one second, he did not even explain his last words.
