"Lord, the enemy's reinforcements are coming." Fazheng said solemnly: "I just saw Chen Deng's figure on the city wall."

"Chen Deng?" Yuan Shu frowned and whispered: "This man's strategy is extraordinary. He is far from being as easy to deal with as Cao Xiu. I'm afraid we won't be able to attack Tongguan as easily as before."

"Yes." Fazheng nodded: "Today our army was attacked by huge rocks before attacking. I guess it was Chen Deng who placed the catapult on the city wall, otherwise the range would not be so far."

You must know that the catapults under Yuan Shu's command have been carefully improved by countless craftsmen in Jiangdong. The core parts are all made of fine iron, and their range is far beyond that of the catapults under Cao Jun. For the sake of safety, Yuan Shu will use the catapult every time.

The catapult was placed at the edge of the firing range from Tongguan, but this time it was counterattacked by the opponent.

Fazheng didn't believe that the poor Cao Cao could improve the catapults in the city to be so sophisticated in a short period of time. The other party must have modified the catapults and placed them on the city wall. With the height of the Tongguan City Wall, Cao Cao's army originally

The catapult range should be able to barely reach the catapult in front of Yuan Shu's army.

"Chen Yuanlong is really smart, turning a weapon for attacking the city into a weapon for defending the city." Yuan Shu sighed. Although it seems to be a very simple transformation, in this era, few people can turn this corner. Just like

The single-sided stirrup was invented for a long time before anyone thought of the double-sided stirrup.

"Chen Yuanlong has a lot of tricks up his sleeve, and he is not an easy person! This time he only showed his sharpness, and I'm afraid there will be more tricks waiting for us in the future." Fazheng sighed softly.

"But in this case, it will probably be impossible for our army to use catapults to suppress the morale of Tongguan. Instead, we will have to worry about the opponent's slings." Yuan Shu shook his head with a wry smile.

Throw stones without attacking the city, and attack the city without throwing stones. Although the catapult is useful when attacking the city level, it can only be used for consumption before the battle. If you continue to throw stones when your own army attacks, the catapult will be frustratingly accurate.

It is estimated that the enemy troops were not hit, and our own soldiers had to rest first.

But if it is used to defend the city, there won't be so many scruples. Our own army is on the city wall, and the trebuchet can hit the outside of the city wall casually. As long as the deflection is not too outrageous, it can always hit the opponent's soldiers. This is a city siege.

Sharp weapons used to defend a city are even more terrifying, and Yuan Shu knows this very well.

"Chen Yuanlong's move not only directly eliminated the role of our catapults and prevented us from participating in the battle. It also made our subsequent siege of the city more difficult and the losses more heavy." Fa Zheng frowned.

"How about using the secret passage in Tongguan?" Yuan Shu thought for a moment and then said.

"Lord, the opponent's trump card has not been revealed yet. Cao's army in Tongguan is currently so large that even if it is used, it may not be of much use. This method should be reserved for when our army has no other way to use it. Now the opponent will use the catapult.

Placing it on the city wall will only prevent our catapults from functioning and cause greater losses," Fazheng said.

"Throwing stones is good for defending the city, but it is not difficult to dodge. Didn't we kill many Tongguan defenders when we bombarded the Tongguan city wall before? It is only suitable for deterring and damaging the opponent's morale. As long as our soldiers lie down when the stones fall.

If you dodge down, the loss shouldn't be much."

Hearing Fazheng's relief, Yuan Shu nodded slightly.

"I hope this Chen Yuanlong will not make other bad moves."

...

Above Tongguan, the officers and soldiers of Cao's army looked at the slender, seemingly frail young man beside the city wall with great admiration. The other party's small arrangement directly forced the enemy to retreat, and also greatly reduced the defense's ability to defend the city.

The difficulty really convinced them.

"Military advisor, you have such a clever plan. In this way, our army not only no longer has to worry about the disaster of flying rocks, but also has an extra weapon to defend the city. It's great!" Cao Xiu said excitedly.

An expert would know if something was wrong as soon as he made a move. Instead of being strict and defensive by following the rules, Chen Deng directly reversed the situation with a few strategies. Cao Xiu really admired this, and became more and more respectful to Chen Deng, and began to ask for advice in private.

Got up.

"The trebuchets only damage the opponent's morale. If we want to defend Tongguan, we can't just rely on these dozens of trebuchets." Chen Deng said calmly without any complacency.

"Military advisor, why did you build an inner wall on top of this wall? This inner wall built in a hurry is not very strong, and the Tongguan wall is not low!" Cao Xiu asked shamelessly.

When Chen Deng heard this, he looked at Cao Xiu with hatred, shook his head slightly and said, "Don't you think there are too many archers under Yuan Gongli and their range is too far? It's true that you made so many wooden shields.

Yes, but it still cannot solve the problem of our archers being suppressed. Build a higher inner wall and place the archers on it so that you will not be afraid of the opponent's archers suppressing it. While protecting the archers from the opponent's attacks, it also

It can increase the striking surface of our archers from a high position."

After saying that, Chen Deng said with some displeasure: "If Zhicai had not taken away all the wells used to attack the city, why would I have bothered? There is no need to build an inner wall, just place the wells directly on the city wall.

Enough."

"Wonderful!" Cao Xiu said excitedly: "Commander, you are indeed very resourceful. In this way, Yuan Shu's two biggest advantages have been eliminated by us, and it will be much easier to deal with the opponent's attack next."

Facing Cao Xiu's praise, Chen Deng did not feel happy at all. These are small tricks. Although they are of great effect, facing Yuan and Liu's combined army of more than 100,000, it is definitely impossible to defend Tongguan with these two tricks.

. If we want to solve Tongguan's dilemma in one fell swoop, we have to start with Yuan Liu.

"In the past two days, you asked the patrolling soldiers to be more vigilant to guard against the other party's plot. In addition, prepare a school of soldiers and let them have a good rest. In two days, we will go out to attack the enemy." Chen Deng said in a low voice.

"What?" Cao Xiu said in surprise: "Military advisor, do you know that Yuan Shu and Liu Bei have elite soldiers and generals under their command. We may not be able to defend the city. Wouldn't it be a recipe for death to go out to meet the enemy?"

"I'm not stupid." Chen Deng rolled his eyes at Cao Xiu who wanted to dissuade him: "Who said I was going to have a head-on confrontation with Yuan Liu? Night attack, night attack, do you understand? Yuan Shu kept harassing our army at night, Yuan Shu

Liu all thought that we would not be able to get out. So we did the opposite, wouldn't we attack Liu Bei at night?"

"But I'm afraid that Liu Bei is prepared! Both Guan and Zhang are powerful generals. Even if the night attack is successful, we may not be able to achieve good results. Maybe Liu Bei's army will be restrained, and Yuan Shu will come up and make the dumplings in the end." Cao Xiu.

He said still very worriedly.

"It's okay. I didn't plan on achieving much results with this night attack, so I just asked you for a school of soldiers and horses. By the way, how many armor weapons of Sergeant Yuan Shu do you have in your hand?"

Although Cao Xiu was very puzzled by Chen Deng's inquiry, he still said honestly: "There are only two hundred sets of armor and weapons, and they are all damaged, but there are more clothes, six or seven hundred."
