The Luanhe River is about 350 steps wide, and more than 2,000 engineers from the engineer battalion, leading more than 10,000 slaves, are in full swing for construction.

In this era, pontoon bridges were erected, and dozens or hundreds of boats (or rafts, bamboo rafts, bamboo rafts) were generally used instead of bridge piers, which were arranged horizontally in the river, with the hull as the piers, and the beams and plates on the bridge deck. The bridge and the river bank are connected by gangboards, trestles, etc., to adapt to the rise and fall of the river. The boat is either fastened to a cable made of brown, hemp, bamboo, or iron, or iron, copper, or stone anchor is fixed to the bottom of the river and both banks, or the cable anchor is used both.

Unlike any army of his time, Li Zhongyi attached great importance to the engineers who opened roads in the mountains and built pontoon bridges in the water.

With the personal participation of Li Zhongyi, Liu Shichang finally found a rapid construction method for quickly erecting a pontoon bridge after continuous exploration and improvement.

On the bank of the Luan River at night, under the guidance of Liu Shichang, the slaves connected the six fishing boats that replaced the bridge piers on both sides of the river into a pontoon unit.

In this arrangement, we can give full play to the advantages of the large number of slaves, so that a large number of construction workers can complete the connection between ships on the bank of the Luanhe River, which undoubtedly saves a lot of time.

At first, only the method of fixing the pontoon bridge on both sides of the river was adopted, and later, due to the strong wind, a cast iron anchor weighing about 100 catties was added to the middle of the river and fixed in the river, instead of a huge cable that was difficult to obtain, so as to speed up the speed.

The sappers also used rafts instead of boats in the rapids of the river to reduce the surface of the water and reduce the water pressure on the bridge. The raft is composed of large wooden rows, with several layers crisscrossing vertically and horizontally.

In order to adapt to the rise and fall of the water level of the Luanhe River, the pontoon bridge must be adjusted at any time, and the method of dismantling or adding a boat section is generally adopted.

Since the Luan River was not wide and the slaves were abundant, the ten pontoon bridges were successfully completed in just one night.

Liu Shichang deliberately found a few two-horse carts full of grain, and galloped back and forth on each pontoon bridge more than a dozen times before sending someone to report to Li Zhongyi.

After Li Zhongyi received the news, he looked at the team of the engineer battalion in front of him, and couldn't help but curl the corners of his mouth slightly, and couldn't help but smile.

Ten pontoon bridges were erected in one night, such a great credit, and if it was a person with a normal mind, he would definitely come to report the good news in person.

Liao Shanhe, who was waiting on the side, rolled his eyes, this Liu Shichang is really a fool, he actually only sent a small team to see the lord, his brain burned out, right?

After Li Zhongyi carefully asked about the process of erecting the pontoon bridge, he rewarded the team with a few red fruits and sent him back.

"Pass my order, the army is ready to go, cross the Luanhe River two hours later, and enter Pingzhou with lightning speed, and hit Yelu by surprise."

Since the pontoon bridge was quickly built, Li Zhongyi decided to simply cross the Luan River in advance, hug the grass and beat the rabbits, take the sheep by the hand, and take Pingzhou first.

At the beginning, when the west went out of Yuguan, the soldiers were very fast, and Li Zhongyi deliberately kept Pingzhou and did not take it, in order to paralyze the Khitan assistant Luanzhou's general Yelu shouted.

Now, it's time for Jerod to shout to pay his debts. If Li Zhongyi is not mistaken, he led the army to surround Yizhou and create a horrific massacre of Yizhou, and the culprit was this Yelu shout.

After several days of carrying heavy supplies onto the ship, the logistics cart of the entire Li Jiajun was already full of grain and other materials, waiting for Li Zhongyi to give the order to set off.

This time when he returned to the division and marched eastward, Li Zhongyi broke the convention, and for the purpose of taking turns to train senior generals, he unexpectedly appointed Song Yunxiang as the commander of the marching army of the school, that is, the commander-in-chief of the former enemy.

Because the strength of Li Yong's cavalry was a little too inflated, Li Zhongyi drew 2,000 Han cavalry and 1,000 party cavalry from him to move with the Guards.

According to the pre-war deployment, Li Zhongyi personally led the Chinese army, including the 3,000 cavalry transferred, to act as the general reserve of the entire army.

After many years of military career, Li Zhongyi has developed a very good habit that no matter how many troops he has at hand, he must always leave behind a general reserve force with full physical strength and super power.

In the Battle of Waterloo, after the emperor made a mistake in judgment and sent out the guards who served as reserves, the Prussian army suddenly appeared on the battlefield, and the emperor could only watch the inevitable defeat without any power to return to heaven.

Li Zhongyi was born as a medical student and belongs to a typical military novice. It's just a coincidence of fate that forced him to transform from a small medical officer to a commander of the army.

Li Zhongyi can't afford to lose, and he doesn't want to lose.

Taking the lessons of the emperor's disastrous defeat in the Battle of Waterloo, Li Zhongyi never dared or forgotten, and has always taken it as a warning.

Before the Battle of Waterloo, in the face of the siege situation in which Britain paid for it and European powers sent troops, the emperor repeatedly won more with less on the frontal battlefield, and the allied forces of the European powers were all over the place.

The French army led by the emperor can be said to have marched from victory to victory, and its achievements were exceptionally brilliant. Because of this, the emperor was carried away by the victory and did not really pay attention to the enemy strategically.

Napoleon overlooked a major event, the generals of various countries were baptized by the French army, a group of famous generals learned war from war, and finally defeated Nathan himself.

Kutuzov took advantage of the strategy of defense in depth, starting from logistics, and implemented the policy of fortifying the walls and clearing the wilderness, preferring to abandon the capital rather than leave half a grain of grain for the emperor, and finally dragged down the emperor's most elite troops.

Wellington's Battle of Waterloo not only delayed the Emperor, but also lured him to send reserves, and when the Prussian army led by Blücher arrived, the Emperor was gone.

Now, the Li family army under the leadership of Li Zhongyi has also achieved invincibility and defeat, in a sense, it is roughly the same situation as the emperor before entering Russia.

Li Zhongyi always warned himself that today's illustrious military might was not easy to come by, and he must be careful and cautious, cautious and cautious, and would rather avoid strong enemies than be too confident.

When the army set off in echelons, Li Zhongyi sat in the second hall to review the official documents, and Ye Xiaolan wrote an abridgement on the small book table on the side as usual.

Li Yong, who was transferred to fight with the Guards, leaned over with a salivating face when Li Zhongyi put down his pen and drank tea, and whispered: "Master, I think about it, many captured Khitans have grown up on horseback since they were children, and it would be a pity if they were abandoned." ”

Li Zhongyi understood in seconds when he heard it, Li Yong, a party barbarian, has more eyes than anyone else, he probably saw the crisis that the cavalry battalion was about to be divided into two, right?

"How do you know?" Li Zhongyi put down the teacup in his hand and deliberately pretended to be confused and asked Li Yong.

Li Yong has been following Li Zhongyi for a long time, and he doesn't dare to say that he knows the temper of his master, at least he sees one thing very clearly: separation of powers and checks and balances has always been a constant theme.

Yang Lie is not only Li Zhongyi's protégé, but also an extremely outstanding deputy marshal of the army, but Li Zhongyi used the rotation method to promote Song Yunxiang to be the inspector of the school and the march deployment.

Li Yong remembers very well that Li Zhongyi once said a gossip that you must not put all your eggs in one basket.

This may not be the original words, but Li Yong pondered the connotation, in fact, it is to cultivate talents in an all-round way, and then select the best of the best.

If Li Zhongyi knew Li Yong's careful thoughts, he would definitely sneer at him and scold him for thinking too much!

There are still many things to be done in the future, such as the Khitan in the north, Annan in the south, Tubo in the west, and the Jurchens in the northeast.

He likes to take precautions, take advantage of the opportunity to take turns to preside over the march, and constantly train his generals, so that he can be stationed in all directions in the future.

As for the idea of dividing military powers, it is not just starting now, but as early as when Hechi was building the army, there was already a rudimentary form, but the current system of separation of powers and checks and balances is more perfect and effective.

Li Yong didn't dare to tell the truth, he smiled and said: "Master, the little ones are just thinking about it, the Khitans are more capable of fighting than the party members, and it would be a pity to only let them be slaves." ”

Li Zhongyi smiled, Li Yong, this kid deserves to be a party barbarian with a ravine, he deliberately exalted the Khitans and belittled the bravery of the party members, this is a disguised expression of loyalty, right?

"Xiang Ming, we haven't chatted for a while, right? So, you sit down and have a cup of tea, rest your legs, and when I finish dealing with the official documents at hand, let's talk about it again, how about it? Li Zhongyi looked at Li Yong with a smile, and the excuse was above board.

Li Yongming knew that Li Zhongyi wanted to hang him, but he didn't dare to behave untamily, so he hurriedly beat his chest and saluted, and said in a trembling voice: "In front of the Lord, how can there be a villain's seat?" The little one has just ridden a horse for a while, and his butt is very upset, so it is better to stand for a while first, and there is no harm in activating the qi, blood and muscles. ”

This is said very beautifully, Li Zhongyi was difficult to find the flaws for a while, he almost laughed, but deliberately scolded with a straight face: "If you are told to sit, you will sit, and Lao Tzu will talk so much, could it be that the skin is itchy again, and you can't smoke it?" ”

Li Yong's stop was two hours, and when Li Zhongyi finally finished reading the official document at hand and ordered him to accompany him to dinner, the heart that Li Yong had been carrying finally reluctantly fell back into his stomach.

Li Zhongyi knew very well in his heart that so far, although Li Yong has been a little cautious, he is generally a trustworthy general.

On the prairie, the strong have always been respected, and it is a matter of course that the weak eat the strong.

As the saying goes, a good bird chooses a tree to perch on. Li Yong is a smart man, and when the Li family's army is becoming more and more prosperous, he borrows 800 courage from him, and he does not dare to move the idea of rebellion.

After eating, Li Zhongyi pulled Li Yongdong for an hour, and after tossing him enough, he said lightly at the end: "Since you think that the Khitans are natural cavalry warriors, then I will give you a warrant." After this battle, how about you select 3,000 Khitannus and add them to the cavalry to serve as a 'burden'? ”

In the old military system of the party members, each tribe took one soldier for every two dings, which was for the "regular army", and it was equipped with one "burden" who served with the army and miscellaneous service, which was collectively called "one copy".

"Yijiao" is the smallest military combat unit of the party. After Li Jiqian rebelled against the Song Dynasty and established the Western Xia Kingdom, he changed to two regular soldiers sharing a "burden" and living in the same tent, which was a new "copy".

Li Yong was overjoyed when he heard this, and he bowed his head, it was not important to have an extra 3,000 "burden", the important thing was that Li Zhongyi trusted him and reused him as always.

PS: It's later, and there's at least one more!
