Unlike improvised trebuchets, heavy return guns have a longer range and require thicker wood for the beam.

However, the soldiers of the engineer battalion, equipped with all kinds of logging tools, thousands of people acted together, and the speed was not slow at all.

In just three days, the officers and men of the engineer battalion had built ten heavy return guns. These return guns, after a test firing without ignition, were enough to smash the cocktail into Yangping Pass.

Li Zhongyi stayed on the top of the mountain for several nights in a row, and he saw the hard work of the soldiers of the engineer battalion.

So, when the preliminary construction of ten heavy return guns was completed. Li Zhongyi immediately spoke, all the soldiers of the engineer battalion, one is counted as one, and each person will be rewarded with half a catty of meat.

The engineer battalion of the imperial forbidden army is not small, with as many as 6,000 people.

Before the Three-Way Army invaded Shu, Li Zhongyi gave Liao Shanhe and Song Yunxiang, each with 1,000 soldiers of the engineer battalion. The purpose is to open the road in the mountains and build bridges in the water.

Today, there are as many as 4,000 soldiers of the engineer battalion working on Jigong Mountain. Fortunately, in the city of Xingyuanfu, a lot of pigs and sheep were obtained and brought to Yangping Pass.

Otherwise, it would be an exaggeration to get half a pound of meat per person.

It is necessary for the horses to run fast and to eat well, which has always been Li Zhongyi's principle of employing people!

In Li Zhongyi's concept, the reason why talents want to betray you is that in addition to insufficient benefits, they are uncomfortable.

Therefore, in the forbidden army of the imperial court, the military salary has always been unusually sufficient. Moreover, the responsibilities and rights of the officers are clearly defined in detail.

Obeying orders, obeying orders, and abiding by rules are the first priorities of soldiers in the Han Empire. This so-called: soldiers take obedience to orders as their duty!

The soldiers of the engineer battalion were very busy, and Li Zhongyi was not idle, he walked around to take a look, took out a small black book from time to time, and quietly wrote it down.

Wang Ken, the deputy commander of the Guards, has been following Li Zhongyi. Li Zhongyi wandered around to see the scene, but Wang Ken closely watched Li Zhongyi's every move, lest the emperor make a mistake.

As the saying goes, there is nothing higher than the rescue. On the other hand, to put the emperor in danger is the most heinous act.

If you want to do a good job, you must first sharpen your tools!

Li Zhongyi stood alone on the top of the cliff, holding a monocular, looking at the Shu army camp from afar.

Coldly, in Li Zhongyi's sight, a general of the Shu army wearing gold armor appeared. On the wall, in front of and behind the gold-armored general, there were all the generals of the Shu army.

Li Zhongyi estimated that this Jinjia general was probably Yang Yuanji, the chief general of the Shu army, right?

Yangping Pass, the danger of guarding three mountains and one river, is the throat of Shu, and it is impossible for the Han army to bypass it.

Therefore, the battle of Yangping Pass is imperative, and Li Zhongyi has already made up his mind to fight.

Now, since Yang Yuanji is unwilling to submit to the Han Dynasty, a tough battle will inevitably unfold.

Li Zhongyi can see it very clearly, Yang Yuanji is a talent, with clear eyebrows and bright eyes. It's just that the huge fire mouth on the corner of the mouth spoils the handsome appearance.

"Wang Ken, tell me, with the strength of our army, how many days can Yangping Pass be lowered?" Li Zhongyi suddenly put down the monocular in his hand, turned his head and asked Wang Ken, the deputy commander of the Guards.

Wang Ken thought about it carefully, clasped his fists and arched his hands: "Your Majesty, with the might of our army's artillery, I'm afraid we can go down to Yangping Pass in three days." ”

Li Zhongyi's eyes flashed slightly, and he smiled: "You are more confident than me?" ”

Wang Ken smiled and said: "Your Majesty, although this Yangping Pass is dangerous, it has left a big flaw in the close distance of Jigong Mountain. Whether it is our artillery or return artillery, it can be shot and hit. In particular, the return cannon that can be used to send cocktails can have a range of more than 700 steps, and even if it is burned, it can burn and defeat the Shu army. ”

Li Zhongyi put his hands behind his back and said with a smile: "Aren't you afraid of burning the entire mountain into a sea of fire?" ”

Wang Ken said solemnly: "Your Majesty, you once said that the soldiers are fierce and the war is dangerous, how can you take into account the gains and losses of a mountain and a village? ”

Li Zhongyi smiled dumbly, Wang Ken is better at talking than Zhang Sanzheng, and he is actually waiting for him here, he can be regarded as a clever ghost!

Times are already different!

In the era of cold weapons, Yangping Pass, surrounded by three mountains, is indeed a one-man pass, and it is impossible to open it.

However, Li Zhongyi not only mastered a large number of artillery, but also possessed an amazingly powerful return cannon. Moreover, the shells of the return cannon are also ready-made cocktails, not stone shells.

After Li Zhongyi circled around Jigong Mountain, he immediately went down the mountain and arrived at the frontal position that Liao Shanhe was responsible for.

In the monoculars, the construction progress of the front position is significantly slower than the construction speed on the Jigong Mountain.

The reason is actually very simple, the guards of the Shu army are not fools. From time to time, large stones or logs were thrown from the walls of the mountain, which seriously interfered with the construction progress of the engineer battalion.

Shu Road is difficult, it is difficult to only allow one car to pass side by side, and the mountain is steep and rugged, and the back attack from the bottom to the top naturally has a disadvantage.

However, according to Li Zhongyi's observation, Liao Shanhe found a way to deal with interference, that is, to build layers of fortresses and keep pushing upward.

Contrary to the perception of ordinary people, the fortification operation under the command of Liao Shanhe was based on felling wood and erecting walls.

To put it bluntly, as long as the wooden wall is stable, even with the continuous interference of the Shu army, the impact is very limited.

"Your Majesty, this place is dangerous, and it is not advisable to stay for a long time."

When Liao Shanhe learned that Li Zhongyi was coming, he hurried over, and as soon as they met, he persuaded Li Zhongyi to leave the dangerous area quickly.

"Your Majesty, this place is dangerous, you can't stay ...... for a long time"

Li Zhongyi waved his hand and said with a smile: "This place is far enough away from the camp of the Shu army, there is no need to be so panicked." ”

"Your Majesty, you are the Emperor of Ten Thousand Golds, or leave here......" Liao Shanhe still persuaded him with no heart.

Li Zhongyi smiled and said: "Don't worry, I have a god and Buddha to protect the body, so it's okay." ”

Liao Shanhe was in a hurry, but he couldn't do anything, because he knew the emperor's temper very well.

Li Zhongyi didn't see Liao Shanhe's appearance of scratching his ears and cheeks, handed the monocular to Wang Ken's hand, and continued to walk up the mountain.

It was too late, it was fast, and a big stone fell quickly from the mountain, mixed with the sound of wind and thunder, and smashed towards Li Zhongyi's side.

"Your Majesty...... Be careful...... "Wang Ken didn't have time to think about it, and when he turned around, he threw Li Zhongyi under him.

Almost in an instant, Liao Shanhe also pounced, and subconsciously lay on Wang Ken's body, and the two of them covered Li Zhongyi to death.

The "click...... slammed into a large tree with a frighteningly loud sound.

"Huh......" Liao Shanhe looked around carefully for a long time, and then let out a long breath of turbidity, "It's so hanging." ”

Wang Ken stared at him twice, watching the boulder roll down the mountain, and then he secretly breathed a sigh of relief, and lowered his head to look at Li Zhongyi carefully.

"Bastard, do you two want to suffocate me?" Li Zhongyi was almost out of breath by Liao Shanhe and Wang Ken, and he counted them down angrily.

"Your Majesty, are you alright, are you alright?" Liao Shanhe stretched out his hand and touched Li Zhongyi's body for a while, fearing that the emperor would be hurt.

Li Zhongyi smiled angrily and reprimanded: "Hurry up, I'm fine." ”

Waiting for Liao Shanhe and Wang Ken, they hurriedly helped Li Zhongyi to stand firmly, and looked Li Zhongyi up and down vigorously, for fear of a slight discomfort.

After Li Zhongyi stood firm, he did not continue to count Liao Shanhe and Wang Ken. After all, they are faithful, and their actions are beyond reproach.

"Your Majesty, you better go back, you can't stay here for a long time."

The rocks still rolled down from time to time on the mountain, and Liao Shanhe was extremely worried, and persuaded the emperor to leave.

Li Zhongyi glanced around, and saw that the guards with knives were also looking at him worriedly, so he smiled and said, "Since you all dislike me, then I will leave." ”

Li Zhongyi's character has always been that after making a decision, he is relieved to boldly let his subordinates play freely.

So, Li Zhongyi did what he said and really returned to the big account.

The soldiers are the elite soldiers of a hundred refinements, they will be the generals of a hundred battles, and they are supported by heavy return artillery and artillery, as long as Liao Shanhe and Wang Ken do not take the enemy lightly, this battle will be won.

The only thing that worries Li Zhongyi is that the casualties of the soldiers may not be small.

After all, the mountain road was narrow, and the soldiers were attacking from low to high. The Shu army has been prepared for a long time, and there should be a lot of weapons such as rolling wood and stones.

However, the general will inevitably die in battle, the crockpot will not be broken from the well, and people will always die if they take the danger!

After Li Zhongyi left, Liao Shanhe and Wang Ken didn't care about their image, and sat directly cross-legged on the ground.

"Dagong, according to the battle plan of the General Staff Division, the general attack will start after dark. Now, the soldiers and horses who climb the mountain have been lurking in place, and the rest is up to Dagong. ”

Wang Ken's qualifications are relatively shallow, and it is appropriate to call Liao Shanhe Dagong, in order to show respect.

Liao Shanhe said with a smile: "Night fighting has always been the strength of our army, as long as you can attract the attention of the enemy with your return artillery and artillery, our main attacking army will definitely be able to quickly break through the enemy camp." ”

Wang Ken said confidently: "Previously, it has been experimented, and the cocktail is no less than ten times lighter than the big stone bullet, but the burning power is huge. If a certain family is not talented, out of ten shots, there must be more than nine shots, which can hit the enemy camp. ”

Liao Shanhe knew very well in his heart that the key to this battle was whether the cocktail and artillery could disturb the enemy's morale and make it impossible to dispatch smoothly.

In this operation, Liao Shanhe was the main attacker, but in fact, it was Wang Ken's department that took the lead in attacking.

After all, the two armies were far apart, and the timing of Liao Shanhe's general offensive could only be called a fire in the Shu military camp.

Taking advantage of the fact that it was still early, Liao Shanhe and Wang Ken got together and discussed for more than two hours, and finally reached an agreed attack plan.

In the dead of night, Li Zhongyi slept soundly, and suddenly, an earth-shattering sound of artillery suddenly woke him up from his sleep.

"Woo ......" Li Zhongyi let out a long breath of turbidity, turned over and sat up, well, it finally officially started.
