Li Yan and others naturally want to make meritorious contributions, but for the defense of the city, Li Yan obviously does not have a very good way, they know the defense of the city better than Liu Bei, as the seat of Guanghan County, and it is also the gateway of Shu County, the defense of the city is stronger than that of South Zheng, and said a lot of suggestions, but it is nothing more than a routine of cutting off food and water, but there is a lot of grain in the city itself, and according to Liu Bei, Zhang Ren has begun to dig a reservoir in the city as early as when Liu Bei counterattacked, and wanted to rely on the trick of cutting off food and water to break through the city. It will take at least a year.

Of course, Li Yan also has a bad move, that is, to drive the surrounding people into the city and increase the consumption of the city, so as to shorten the time that the city's grain storage can support, and he can also take the opportunity to send some fine work to mix in and sabotage.

Let's not talk about the feasibility, the strategy itself alone is a little disgusting, and the surrounding territory is basically occupied by Liu Bei, that is to say, the people here are already Liu Bei's people, if you really do this, where will Liu Bei's image of benevolence go? This strategy was naturally rejected by Liu Bei.

Liu Yi has seen the city defense of the city, not to mention that it is invulnerable, but there is no big loophole that can be exploited, there are still so many siege routines, Pang Tong can't think of any tricks, Liu Yi is even worse, now in the siege of the city, Liu Yi can play a role, is to optimize the siege equipment, Liu Bei used from Fuxian, Baishuiguan these places seized well fences, catapults, of course, in terms of today's general technology, these things are not outdated, but in Liu Bei's army, it is a little outdated.

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

Let's take a look at that Zhang Ren's ability.

Liu Yi called Yang Ren over and asked Yang Ren to help him transfer the timber and the craftsmen accompanying the army.

"Sir, are you going to do a well?" Yang Ren looked curiously at Liu Yi's frame, which was as high as six zhang, and said curiously, this height is basically the same as the city wall of Yucheng.

"Yes and no." Liu Yi nodded, and shook his head again, this is indeed the frame of the well block, but it is wider than the well wall, six zhang high, but also five zhang wide, and the top can run horses, if it is replaced by an archer, the arrow tower on the top can accommodate hundreds of people.

Liu Yi first ordered people to place the wheels, different from the ordinary four wheels, this well fence is thirty-two wheels, the arrow tower has not been done, but Liu Yi has ordered the craftsman to make three swing ladders, this swing ladder is not to the top of the arrow tower, but to the bottom of the arrow tower, a vertical plate when there, can be moved through the bearing, the top of the vertical plate with a barb, in Liu Yi's design, this is a function with the ladder of the ladder, as long as the siege is close to the city wall, the vertical plate is placed down, directly can hook the city wall, The soldiers below can quickly rush up through the swing ladder and rush directly to the city wall, while the archers of the arrow tower are a little higher than the opponent's city wall, and can also shoot arrows at the opponent to suppress and cover the siege of the soldiers.

This is Liu Yi's new siege weapon that combines the effects of the ladder and the well fence into one, but the effect has to be verified on the battlefield.

Yang Ren looked at this well, which was almost the frame of a city wall, and looked at Liu Yi in amazement: "Sir, how can this well be promoted?" ”

Liu Yi was still very satisfied with his design, and said: "The manpower needed is naturally more, but thirty-two rounds, when it can be promoted, you let the soldiers go up and try it." ”

Perfect Well: +36 Sturdy, +37 Range, +37 Movement Speed, +39 Fighting Spirit, +38 Stability

Of course, this movement speed is only relative, after all, it is a stupid heavy weapon, and no matter how many attributes it adds, no one can run fast.

Yang Ren heard this, estimated it, and sent more than 30 archers to climb up the well, although the spiral ladder is not directly leading to the arrow tower, but there is a bamboo ladder sticking out at the bottom of the arrow tower, just above the top of the spiral ladder, but those who have fear of heights may not have the courage to climb up.

Soon, thirty archers went up to the arrow tower, and Yang Ren ordered thirty-two soldiers to push the well, although it could be pushed, but it was quite difficult, not to mention the speed of movement compared to ordinary wells, the thirty-two soldiers were red and red-faced, and it took a long time to move only a dozen steps.

"Double the manpower!" Liu Yi looked at Yang Rendao, there are horizontal bars as a driving force under this well, and each wheel can be pushed by six people.

Yang Ren nodded, at such a speed, when it is pushed to the opponent's city wall, maybe he will have to withdraw his troops.

Sixty-four people pushed, and the speed was a little faster, but in the eyes of Liu Yi and Yang Ren, who were watching, it was still a little slow, not as good as ordinary Jingqi.

"How much manpower does it take to build a normal well?" Liu Yi turned his head to look at Yang Ren.

"Thirty-two!" Yang Ren frowned and said, Generally, the well is not pushed like this, the territory is a whole, and the wrestlers can only push it outside, and they have to brave the rain of arrows.

"Sixty-four more!" Liu Yi silently estimated in his heart and said in a deep voice.

"Whoa!" Yang Ren agreed, and added sixty-four more people to go up, this time, the speed of the well was obviously a lot faster, and it was very stable.

"I'll go and ask the lord, try this thing next time you attack the city, if it's useful, I'll make a few more!" Liu Yi's eyes also flashed with excitement, as long as five or six planes go up, and then set up a baffle in front of them to protect the wrestlers who are responsible for pushing the well, Liu Beijun can ignore the city wall and directly rush to the city wall along this new-style well, and the arrow tower can also suppress the defenders, so that the siege can be much simpler.

"Sir, I think this thing can be made into a few more fights, maybe it can be won in one battle!" Yang Ren looked at Liu Yi and smiled.

"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 copes.

Liu Bei was also amazed when he saw the giant well made by Liu Yi.

"Bojun, change the guard." Zhang Ren took his guards to the city, looked at Deng Xian, who was sleepy-eyed, and said with a smile.

"There is justice in labor." Deng Xian nodded, he hadn't slept all night, at this moment he looked depressed, and he needed to take a rest, and complained in his mouth: "I don't know when this Liu Bei will be willing to retire?" ”

When Zhang Ren heard this, he sighed, I'm afraid that some people have to wait, for Liu Bei's retreat, he is not as optimistic as Deng Xian.

Liu Bei is menacing this time, and he has already laid a foundation in Shuzhong, and has Hanzhong as the backing, how can he say that he will retreat, this city must be defended, otherwise once the city is lost, the entire Guanghan will become Liu Bei's territory, and when the time comes, it will be even more difficult to retreat Liu Bei.

Deng Xian didn't wait for Zhang Ren to answer, turned around and was about to go downstairs, when he suddenly heard a horn in his ears, and his face suddenly changed, this is Liu Beijun's horn, but on weekdays, Liu Bei's siege time is basically fixed, why is it so early today?

Zhang Ren's face became solemn, while ordering people to quickly change the guard, while building a pergola with his hands, he looked far away, the fog in the early morning in Shu was relatively heavy, and the general war would start after the fog had dispersed.

"What's that?" Deng Xian on the side widened his eyes and shouted loudly as he pointed to the blurred silhouette in the distance.

Zhang Ren's eyes were fixed, his eyes were not as good as Deng Xian's, but looking in the direction Deng Xian pointed, his complexion gradually became solemn.

At this time, the morning sun is about to rise, and the fog that is entwined between the mountains and mountains is rapidly dissipating, and through the rapidly dissipating mist, it seems that a huge thing is moving towards this side.

Liu Beijun, who was spreading around, had already appeared in sight, thinking about it like an ant tide, and the speed was not too fast, as if he was deliberately waiting for something.

As the behemoth approached, the fog gradually dispersed, and the appearance of the behemoth finally became clear in the sight of the defenders of the city.

The behemoth is a city wall, seven zhang high, five or six zhang high, with a wooden arrow tower at the top, and the wall below is also covered with wooden planks.

Deng Xian looked at the arrow tower that was higher than the city wall of this city, and said with a somewhat ugly face: "Jing Yan? ”

Zhang Ren's face was not good-looking, and he nodded silently, judging from the shape, there is no doubt that the well is so big, but who has such a big well? And when were they built? How did such a large section of the city wall move?

In fact, the so-called wall of the well is also an empty shelf, but the visual impact caused by the city wall seems to move to this side out of thin air, but it makes the Shu army defending the city feel inexplicably depressed.

"Trebuchet!" Seeing that the other party is getting closer, the archers on both sides have begun to exchange hands, the people on the opponent's arrow tower are condescending, the range is unusually far, separated by a distance of nearly one hundred and fifty steps, they have begun to release arrows, and the cluster of arrows shot can be shot directly on the city wall, and the bows and arrows on the city wall cannot reach the other party at all, Zhang Ren ordered the shield hand to come over first to block the sparse arrows, and at the same time ordered the trebuchet to turn around and want to attack the well.

Generally, the accuracy of the trebuchet is very poor, but the opponent's well is a little too big, and for the trebuchet, it is a live target.

As the well is closer, the arrows of the city wall can also be shot into the well, but the archers on those arrow towers are blocked by a large number of baffles, and their lethality is limited.

The distance between the two sides is getting closer, Liu Beijun's ladder has been set up on the city wall, the attention of the defenders naturally can't just fall on a well, the battle between the two sides began, Zhang Ren looked at the behemoth, and ordered all the trebuchets to focus on the well.

Boom boom boom~

In the continuous bombardment, a lot of potholes were smashed out of the well block, after all, it is a wooden plank, even if it has solid attributes, it can't withstand the slamming of stones as big as a human head, but for the well block, most of these stones are smashed into wooden planks, and they do not hit the frame, and they are still as stable as Mount Tai.

Hollow?

Zhang Ren looked at the gap that was smashed out, and could faintly see Liu Beijun's soldiers below, and his eyes moved......
