If a trebuchet is used, the speed of filling the moat may be reduced. But when weighing human lives, Huang Li still chooses the former without hesitation.

The fortifications piled up in front of the trebuchet can effectively protect the soldiers operating the trebuchet. Although it is not absolutely safe, it is quite difficult to hit accurately with the accuracy of the front-loaded artillery.

"I think we can use trebuchets to attack the enemies on the city." Liu Xiang looked at Huang Li and said uncertainly: "If the fortifications are strengthened, the artillery will not be able to destroy them easily."

Huang Li smiled and said, "You are right. From this distance, throwing stones weighing more than ten kilograms can indeed hit the Qing soldiers at the top of the city."

Compared with Li Yue and Yuan Dongbao, Liu Xiang is slightly taciturn.

But Huang Li discovered that although he was poor at speaking, he was good at thinking and was of the languid kind. If he were paired with a pair of thin-rimmed glasses, he would definitely be the dog-headed strategist of a certain big boss.

As expected, Liu Xiang laughed evilly and said, "It's not that we have to use stones. I have an idea, so I have to prepare it."

Huang Li waved his hand and said: "Go ahead and prepare. Anyway, we don't plan to attack the enemy for the time being."

Filling the moat and paving the way for excavation of tunnels are the top priority. The trebuchet only has the ability to fight back, and Huang Li did not expect to use the trebuchet to defeat the artillery on the city.

There is a generational difference between trebuchets and artillery, and they are already obsolete weapons. Even if they are made larger and thrown farther, it will only increase the target and make it easier to be destroyed by artillery.

However, the use of trebuchets to attack the Qing soldiers on the city is not only about the size of the victory, but also has the effect of disrupting the sight and hearing of the Qing soldiers and covering the excavation of tunnels.

Busy work continued until the sky turned white and the trebuchets were all put in place. The ring fortifications were heightened and reinforced, and Huang Li breathed a sigh of relief.

"Mr. Huang, all fifteen gun emplacements have been completed." Ying Zheng finally understood what this fortification was for, and came to ask Huang Li for instructions, "The general thought that more fortifications could be built so that the trebuchets could come.

Release as you go, or move to avoid enemy cannons."

Huang Li admired the bearded general more and more, and said with a smile: "General, you should think carefully, so just do it!"

The distance has been calibrated, and a dozen or dozens of trebuchets are arranged along the moat, which is quite powerful. Anyway, there are plenty of trees, so the craftsmen can work day and night.

Huang Li has already seen the power of ancient artillery. In movies and TV dramas, the cannonballs falling to the ground, the firelight rising, and the smoke filling the air do not exist. They are just pyrotechnics special effects, exaggerations to gain attention.

Although the artillery has a dazzling sound and light effect when it is fired, the power of the big iron pellet is indeed limited. In Huang Li's view, it has a greater effect in frightening the opponent.

The loud bangs and the spitting of fireworks are truly astonishing in power, and they can demoralize the enemy and make them fearful and nervous.

Of course, if there are a sufficient number of artillery and ammunition, the artillery can be used to siege the city, which can minimize casualties.

The sky gradually gets brighter, the white fish belly turns to pink, and the fiery red sun is about to rise above the sky.

The soldiers and civilians who filled the trenches have retreated, and they will eat and rest. Another group of people will take their place and continue the unfinished work.

Judging from the progress, it cannot be said that it has been overfulfilled. However, as Yuan Zongdi and others estimated, in one day and one night, the expected goal can be achieved.

The trebuchet has all been placed in place, the weight box is filled with stone sandbags, and the ammunition bag at the long arm end is also filled with sandbags, ready for test firing.

The Qing troops on the city finally saw the scene below the city clearly. Mounds of earth and sandbags were scattered everywhere. Many damaged carriages were thrown onto the mounds. Curved roads surrounded the mounds of sand and earth.

The moat, which is four to five feet wide, has been mostly filled up in several places, squeezing the water flow until only a foot-wide channel is left. There are even one or two places that have been completely blocked, and water can only seep out.

Mu Shenghui scratched the entrance of the battlements and looked at it for a long time. He was not sure what the opponent had done. What was the semicircular fortification used for? Could it be that the Tibetans were shooting cold arrows at the city?

At this time, Huang Li had returned to the camp, eating hot meals and regaining his energy. It was just that he had lost a few hours of sleep at night, which was nothing considering his age and body.

"Sir, let me take command of the trebuchet!" Li Yue asked Huang Li for help while eating. "I learned a lot when I was in Xingshan. Now, it's time to practice more."

Huang Li pondered for a moment, shook his head and said, "It's better not to take risks. If something happens to you, I won't be able to report it to Linguo Bus."

Being called a bodyguard was to protect his own safety. But because of Li Yue's identity, Huang Li had to treat it carefully, so as not to offend Li Laiheng.

If he was not his bodyguard, but was under the command of Yuan Zongdi or Hao Yaoqi in the army, then the pressure would not be on Huang Li.

In fact, Huang Li felt quite unfree with the three young princes around him. Of course, they were doing it for his own good, so he had to be grateful and understandable, and he couldn't distinguish between good and bad.

In the eyes of others, Huang Li is just a rookie on the battlefield, a talkative recruit. In addition, due to his status, it is reasonable to take care of him in every aspect.

Li Yue said stubbornly: "We are fighting in battle, and our swords and guns have no eyesight. How can my father be blamed for this? Letting someone go with the army also means to gain experience. How can we just hide behind."

Huang Li scratched his head and said helplessly: "Okay, let's go together. There are too few soldiers who have simply learned in Xingshan. We need to train more."

Operating the trebuchet is very simple. You just need to pull down the winch, load the ammunition, and then break the hook to release the long arm. However, it is not easy to hit accurately.

After all, artillery can hurt people by the bounce of the shells, while the trebuchets basically rely on the stone bullets falling from the sky, and the probability of hitting the target is even smaller, unless the number and density of the stone bullets are used to make up for it.

Huang Li couldn't work on paper to calculate the trajectory and range of the oblique throw. Besides, he couldn't remember what the oblique throw formula was!

Moreover, with the level of education in ancient times, there were not many people in the entire Ming army who were literate and able to understand mathematical calculations and physical principles.

Therefore, Huang Li came up with a stupid method, which is similar to mathematical table calculation.

After many practical operations, the data of counterweight, bullet weight and firing range were recorded and compiled into a booklet as a basis for the soldiers operating the trebuchet.

Check it out now. Once you know it by heart, you will be able to operate it freely based on experience.

Among them, ranging is the most critical and basic technology. Not only trebuchets, but also artillery and various long-range weapons. If the distance cannot be measured accurately, there is no hope of exerting much power.

Fortunately, Huang Li also learned the eye-tap technique, which can be taught to soldiers who are smarter and have strong comprehension ability. For example, Li Yue, Liu Xiang, and Yuan Dongbao. Ordinary soldiers are uneducated and may be slower to master it.
