Wu Zhi looked at the strong confidence on Liu Laosan's face and couldn't help but feel a little more confident that he could overcome the crisis in front of him this time.
Wu Zhi reached out and took out a drawing from his arms. It was a drawing he had sketched on the carriage these days, a drawing for the production of a jet cannon to disturb the enemy.
Above, not only the appearance of the enemy-disturbing jet cannon is described in detail, but also the manufacturing process of this object is clearly depicted in the form of a cross-section next to it.
Liu Laosan was very interested in Wu Zhi's extremely realistic painting method.
While carefully observing Wu Zhi's painting techniques, he pondered the feasibility of developing this kind of weapon.
However, after all, a good woman cannot make a meal without rice. No matter how good Liu Laosan's craftsmanship is, there are still some links that cannot be created in the current environment on Shuibo Liangshan.
Of course, the most typical object is the barrel that serves as a jet cannon to disrupt enemies and launch vehicles.
That thing must not only hold cannonballs, but also a certain amount of gunpowder to serve as propellant.
Although Liu Laosan didn't know much about gunpowder, he could tell from Wu Zhi's words that the power of that thing's explosion was quite astonishing.
If an ordinary bamboo barrel is used, its strength may not be able to withstand the force of the instant explosion of gunpowder.
But what if a metal barrel is used?
Although the metal gun barrel is enough to meet the requirements of firing, the craftsmanship is not what can be achieved on Shuibo Liangshan now.
When Liu Laosan told Wu Zhi what he was worried about.
Wu Zhi also knew that what Liu Laosan said was true.
But there was nothing he could do.
You can't build the shells that disturb the enemy's jet cannon, and then let your soldiers hold those things and throw them at Song Jiang's army, right?
We can leave aside the question of whether it is dangerous. Simply speaking, the throwing distance is not far enough.
Gradually, the silence of the past returned to the hall.
The old man, the young man, and the young man all fell into deep thought over such a technical problem.
Suddenly, Liu Laosan's eyes lit up.
Because of him, he thought of a very good alternative.
"Brother, I have thought of a very clever idea."
"Besides, the difficulty of manufacturing is definitely much simpler than that of an iron gun barrel."
When Wu Zhi heard the news, his frown instantly relaxed.
So he quickly urged Liu Laosan who was sitting next to him in a hurried tone.
"Quick, quick, hurry up."
Liu Laosan glanced at Wu Zhi with some embarrassment.
"But that thing belongs to the control machinery of the imperial court."
"Although I have seen it once or twice, I may not be able to create it."
Wu Zhi glanced at Liu Laosan angrily.
"In that case, what's the use of telling me?"
But as soon as Wu Zhi finished speaking, Liu Laosan started talking.
"Although I don't know how to make this kind of thing, there are at least two or three leaders on Liangshan Mountain who have definitely seen those instruments."
"Maybe, they may have used it themselves."
"Even if they don't know how to do it, as long as they explain the principle of emission and the materials used to the little ones."
"Then it won't take long for the little old man to build a few planes for the big brother."
After Wu Zhi heard this, he nodded firmly.
Then, he pulled Liu Laosan and walked out of the hall.
The leaders they are looking for are the flower monk Lu Zhishen, the leopard-headed Lin Chong and the green-faced beast Yang Zhi.
One of these three people once served as a prefect under Laozhong Jinglue Xianggong and Xiaozhong Jinglue Xianggong.
One, was once the instructor of the 800,000 Imperial Guards in Tokyo.
And the other one was once the envoy under the commander-in-chief of Tokyo Palace.
The three of them have seen countless military equipment.
When Liu Laosan told the three of them about the equipment he was thinking of.
The three people laughed one after another.
Among them, the first one to speak was Lu Zhishen.
"Oh, the Sa family thought it was something rare."
"Isn't that the catapult used in siege?"
"This kind of thing is very simple. Although I have not personally participated in building it, I know the principle clearly."
Immediately afterwards, Lin Chong and Yang Zhi, who were standing next to him, were also describing the catapult in their impressions.
When Wu Zhi saw that these people knew so much about this object, he immediately asked the four of them to temporarily form a catapult research team.
Lin Chong, Lu Zhishen and Yang Zhi were responsible for providing production direction, while Liu Laosan transferred two platoons from the construction and manufacturing army to be responsible for the specific implementation of production.
Bai Sheng, on the other hand, led the remaining platoon of the construction and manufacturing army to repair the bamboo arrow towers destroyed by Song Jiang's army under the cover of night.
While the catapult research team was stepping up the development of catapults, Song Jiang, Wu Yong and others continued to attack Liangshan Dazhai.
A large number of rockets were used in an attempt to burn the gates of Liangshan Dazhai and the bamboo arrow tower to ashes.
They launched a surprise attack at night, hoping to break into the village while the soldiers guarding the gate were tired.
There are many other means.
However, they were all blocked out by the soldiers guarding the gate of the village and the V-shaped bamboo arrow towers providing crossfire cover.
At present, although Liangshan Dazhai has done a good job in defense.
But persisting in this way is ultimately not an option.
What's more, the initiative in the war is now firmly in the hands of Song Jiang.
As long as he wants to fight, he can use any method and any time to carry out uninterrupted attacks on Liangshan Dazhai.
As for the brothers led by Wu Zhi, for now, they can only stay in Dazhai fearfully.
If a good strategy to defeat the enemy cannot be found in time, the isolated and helpless Liangshan Dazhai will inevitably end up with the village destroyed and people killed.
Not only Wu Zhi knew this, but Wu Yong on the other side of the Song River also knew this truth.
Therefore, the Song Jiang army, which had been unable to break through the Liangshan Dazhai for a long time, gradually slowed down their offensive.
Its purpose is also extremely simple.
Just waiting for the best opportunity to fight, and then take down the Liangshan Dazhai in one fell swoop.
Of course, not everyone in Song Jiang's army could understand this kind of foresight.
At this time, Li Kui, smelling of alcohol, barged into Song Jiang's tent.
The purpose of his coming here this time was to ask his brother Song Jiang and his always resourceful military advisor brother.
Why have they been calling for formation for days, but they still refuse to lead all the leading soldiers to fight and seize the stronghold with all their strength?
