Li Yan and others naturally wanted to make contributions, but Li Yan obviously had no good way to defend Luocheng. They knew better than Liu Bei about the defense of Luocheng. As the capital of Guanghan County and the gateway of Shu County, Luocheng's defense was stronger than Nanzheng. He said a lot of suggestions, but it was just a routine of cutting off food and water. However, Luocheng itself had a lot of food. According to Liu Bei, Zhang Ren had already started digging a reservoir in the city as early as when Liu Bei counterattacked. It would take at least a year to break through Luocheng by using the move of cutting off food and water.

Of course, Li Yan also had another trick, which was to drive the people around him into Luocheng and increase the consumption of Luocheng, so as to shorten the time when Luocheng's grain storage can be supported. He could also take the opportunity to send some detailed works to infiltrate and destroy them.

Not to mention the feasibility, this strategy itself alone makes people feel a little disgusted. The surrounding territory was basically occupied by Liu Bei. In other words, the people here are already considered Liu Bei's people. If they really do this, where will Liu Bei's image of benevolence and righteousness be put? This strategy was naturally rejected by Liu Bei.

Liu Yi has seen the city defense of Luocheng. It is not flawless, but there are no major loopholes that can be exploited. There are still so many tricks for siege. Pang Tong couldn't think of any tricks, and Liu Yi was even worse. Now in terms of siege, the role Liu Yi can play is to optimize the siege equipment. Liu Bei used the well railings and catapults seized from Fu County and Baishuiguan. Of course, with the general technology today, these things are not out of date, but they are a bit out of date in Liu Bei's army.

Liu Yi has also studied these siege weapons during this period. Since Li Yan and others couldn't come up with any good ideas, the final problem came back to the siege itself.

Let’s take a look at Zhang Ren’s ability.

Liu Yi called Yang Ren and asked Yang Ren to help him transfer wood and military craftsmen.

"Sir, are you going to make a well railing?" Yang Ren looked at Liu Yi curiously, with a frame of six feet high, and said curiously that this height is basically the same as the Luocheng city wall.

"Yes, no." Liu Yi nodded and shook his head again. This was indeed the frame of the well railing, but it was wider than the well railing, six zhang high, but five zhang wide, and it could be run on it. If it were an archer, the arrow tower on the top could accommodate hundreds of people.

Liu Yi first ordered people to place the wheels. Unlike ordinary four wheels, this well railing is thirty-two wheels. The arrow tower has not been made yet, but Liu Yi has already ordered the craftsmen to make three spiral ladders. This spiral ladder does not lead to the top of the arrow tower, but to the bottom of the arrow tower. When a vertical plate is there, it can be moved through the bearing. The top of the vertical plate has a barb. In Liu Yi's design, this is the same as the barb of the cloud ladder. When siege, as long as the vertical plate is approached, the vertical plate can be placed down and directly hooked on the city wall. The soldiers below can quickly rush up through the spiral ladder and rush directly to the city wall. At the same time, the archers in the arrow tower are higher than the opponent's wall and can also shoot arrows at the opponent to suppress the soldiers to attack the city.

This is a new siege weapon that Liu Yi combined the effects of cloud ladders and well rails into one. However, the effect must be verified on the battlefield.

Yang Ren looked at the well railing that was almost framed by a city wall, and looked at Liu Yi in surprise: "Sir, how can this well railing be pushed?"

Liu Yi was still very satisfied with his design. He said, "There is naturally more manpower required, but there are only thirty-two rounds. If you can push it, let the soldiers go up and try it."

Perfect well railing: Strong +36, range +37, movement speed +37, fighting spirit +39, stable +38

Of course, this movement speed is only relative. After all, it is a bulky weapon. No matter how many attributes are added, no one can run fast.

After hearing this, Yang Ren estimated that more than 30 archers had been sent to climb the well railing. Although the spiral ladder did not lead directly to the arch tower, there was a bamboo ladder protruding from the bottom of the arch tower, just above the top of the spiral ladder. However, those who are afraid of altitude may not have the courage to climb up.

Soon, thirty archers went up to the arch tower, and Yang Ren clicked another thirty-two soldiers to push the well railing. Although it could be pushed, it was quite difficult. Not to mention the movement speed of ordinary well railings, the thirty-two soldiers were all red in their faces and took a long time to move only a dozen steps.

"Add twice the manpower!" Liu Yi looked at Yang Ren and said. There were horizontal bars under the well railing as the driving force, and each wheel could be pushed by six people.

Yang Ren nodded. At this speed, when he pushed to the opponent's city wall, he might have to withdraw his troops.

Sixty-four people pushed the ball faster, but in the eyes of Liu Yi and Yang Ren who were watching, they were still a little slow, not as good as ordinary well railings.

"How much manpower is required for the well railing?" Liu Yi turned his head and looked at Yang Ren.

"Thirty-two people!" Yang Ren frowned. Generally, the well railing is not pushed like this. The territory is a whole. The strongman can only push it outside, and he has to brave the rain of arrows.

"Add another sixty-four people!" Liu Yi estimated silently in his heart and said in a deep voice.

"Here!" Yang Ren agreed and added sixty-four more people to go up. This time, the speed of the well railing was significantly faster and very stable.

"I'll ask my lord to try this item next time I attack the city. If it works, make a few more!" Liu Yi's eyes also flashed with excitement. Just five or six frames were used, and then set up a baffle in front to protect the strong men responsible for pushing the well railing. Liu Bei's army could ignore the city wall and rush up the city wall directly along this new well railing. The arrow tower could also suppress the defenders. In this way, siege would be much easier.

"Sir, I think you can make a few more of this thing, maybe you can win in one battle!" Yang Ren smiled at Liu Yi.

"Don't worry, let's see how the enemy responds first." Liu Yi shook his head. This thing is not out of the technical level of this era, let's see how the other party deals with it.

When Liu Bei saw the giant well railing made by Liu Yi, he was also amazed.

"Bojun, change your defense." Zhang Ren brought his personal guards to the city and smiled at Deng Xian with a sleepy face.

"It's just a matter of work." Deng Xian nodded and did not sleep all night. At this moment, he looked listless and needed to rest. He complained: "I don't know when Liu Bei will withdraw his troops?"

When Zhang Ren heard this, he sighed. He was afraid that some people would wait. He was not as optimistic as Deng Xian for Liu Bei's withdrawal.

Liu Bei is coming in a fierce manner this time, and has already established a foundation in Shuzhong and has Hanzhong as a backing. How can he retreat at any time? Luo City must be defended, otherwise, once Luo City is lost, the entire Guanghan will become Liu Bei's territory. At that time, it will be even more difficult to retreat Liu Bei.

Deng Xian turned around and was about to go downstairs without waiting for Zhang Ren to answer. He suddenly heard a horn sound in his ears, and his face changed suddenly. This was the horn of Liu Bei's army. However, on weekdays, the time for Liu Bei to attack the city is basically fixed. Why is it much earlier today?

Zhang Ren's expression became solemn. While ordering people to change defenses quickly, he set up a canopy with his hands and looked out into the distance. The fog in Shu was quite heavy in the morning. Generally, the war would only start after the fog dissipated.

"What is that?" Deng Xian, who was standing beside him, widened his eyes and pointed to the blurry outline in the distance and shouted loudly.

Zhang Ren's eyes narrowed. His eyes were not as good as Deng Xian, but he looked in the direction Deng Xian pointed, and his expression gradually became solemn.

At this time, it was when the sun was about to come out before it was coming out. The fog wrapped around the mountains and ridges was rapidly dissipating. Through the fog that quickly dissipated, a huge creature seemed to be moving towards this side.

The Liu Bei army spreading around him had already appeared in sight, and was like an ant tide, thinking about the sweeping here. The speed was not too fast, and it seemed that he was deliberately waiting for something.

As the behemoth approached, the fog gradually dissipated, and the appearance of the behemoth finally became clear in the sight of the soldiers guarding the city.

The huge creature was a city wall, seven feet high and five or six feet tall. At the top was a wooden arrow tower, and the wall below was covered with wooden boards.

Deng Xian looked at the arrow tower that was taller than the walls of Luocheng, and said with a somewhat ugly expression: "Minglan?"

Zhang Ren's face was not good-looking, and he nodded silently. Judging from his appearance, it was undoubtedly a well wall. But whose well wall was so big? And when did they build it? How did such a large section of the city wall move?

In fact, the so-called wall of the well railing is just an empty frame, but the visual impact caused by the city wall moving out of thin air made the Shu army guarding the city feel inexplicably depressed.

"Takemaster!" As the other party was getting closer, the archers on both sides had already begun to fight. The people on the other party's arrow tower were at a high altitude, with an extremely long range. The arrows were shot at nearly 150 steps away. The clusters of arrows could be shot directly onto the city wall. The bows and arrows on the city wall could not reach the other party at all. Zhang Ren ordered the shield hand to come first to block the sparse arrows, and ordered the catapult to turn the direction and start an attack on the well railing.

Generally, the accuracy of the catapult is very poor, but the other party's well rail is a bit too large. For the catapult, it is a living target.

As the well gate approaches, the arrow clusters of the city walls can also shoot to the well gate, but the archers on the arrow tower have a large number of barriers to block them, and their lethality is limited.

The distance between the two sides was getting closer, and Liu Bei's army's ladder had already been laid on the city wall. Naturally, the defenders' attention could not only land on a well railing. The battle between the two sides began. Zhang Ren looked at the giant creature and ordered all the catapults to aim at the well railing to attack.

Boom boom boom boom ~

Amid the continuous bombardment, many holes were smashed on the well railing. After all, they were wooden boards. Even if they had solid properties, they could not withstand the smashing of stones as big as human heads. However, for the well railing, most of these stones smashed the wooden boards and did not hit the frame, and were still as stable as Mount Tai.

Hollow?

Zhang Ren looked at the cracked gap and could vaguely see the Liu Bei army soldiers below, and the divine light in his eyes moved...
