No change

Concern is chaos, Xiong Jing saw that Fei Jing was injured and was worried that he would die at the hands of the Qin people, so he couldn't help but order the trumpet to be blown. In fact, the 370-pace-wide river channel in the gutter was not enough for so many cavalry to rush and fight, and the two sides were huddled together after the first hedge.

Fighting on a simple horse, the Qin cavalry is not as good as the Chu cavalry wearing huge armor and comprehensive protection, but huddled together like a synchronous battle, the Chu cavalry can not give full play to the advantages of the dragon horse, and the result is a cavalry battle that both sides are extremely disgusting, before the cannon sounds, people on both sides have withdrawn from the river one after another. When the artillery was dragged up the embankment and fired, the Qin army immediately sounded the cymbals, and the Qin cavalry retreated like a tide.

In the roar of the cannon, Fei Jing came back to restore his life. Before Xiong Jing could speak, he pleaded guiltily and said, "The minister is careless, and he is good at fighting with Qin Qi. ”

According to the shogunate's plan, after the Chu army arrived on the west bank of the ditch, it had to drag artillery up the embankment to protect the workers and dig the earth. Cavalry battles were not only redundant, but could also affect the established plans, but fortunately, the cavalry battles ended quickly and did not stall for time.

"Go to the medical camp first, and then go to the army to be punished." Xiong Jing's face was expressionless, and after speaking, he turned his head to the Qin army formation on the other side of the river embankment.

The camp of the sand sea is on the east side and not on the west side, so the embankment on the east side of the gutter is higher than on the west side. The western embankment is just over a foot above the ground, and the eastern embankment is only a few feet above the ground, about one and a half or six feet. Coupled with the snow cover, all Xiong Jing could see was a dense row of towering chieftains, military flags fluttering in the wind, and a feather on behalf of the general. Unfortunately, soon, as the Chu army engineers ignited a fire on the inside of the opposite embankment, the dense spears suddenly disappeared.

"The Qin people sit down." At this time, the nest car has been erected on the embankment, and the nest car with a height of six or seven zhang can clearly see the actions of the Qin army behind the embankment on the opposite bank, and you can also see Wang Jian and the Qin prince Fusu, the general of the Qin army under Yujing, as well as a cadre of strategists standing on the side of the two.

Liu Chi, who was low eyebrows and pleasing to the eyes, stood beside Wang Qian. He knew the operation of the entire shogunate best, and Wang Jian imprisoned him not to punish him, but to not want him to spread panic. During the decisive battle, Liu Chi naturally had to stand in the middle of the battle, and many things in the battle were not something that Wang Jian could handle alone, only in the presence of Liu Chi, the old man of the shogunate, he could seize the most favorable opportunity on the unpredictable battlefield.

When the nest car reported that the Qin people were sitting, Liu Chi also spoke to Wang Jian again, "The Jing people have many witch medicines, so they must blow up this causeway, and although our army's trebuchets do not retreat, they should also take their horses and prepare to leave." ”

Using the east embankment of the Yin Ditch as a fortification to block it was a defensive plan formulated by the shogunate earlier to prevent the Chu army from attacking the Sand Sea. Now that the two armies are in a decisive battle, it is not impossible for Wang Jian to use the east embankment of the gutter to intercept the Chu army. If the Chu army rushed forward, it would be severely hit by the Qin army's dense crossbows and piles of fire and oil bombs, but the battle of the chasm had already shown that this could not really hinder the Chu army.

Liu Chi's suggestion was very pertinent, and Wang Jian immediately issued an order. Seeing this, Liu Chi said again: "The subordinates think that if the earth is not frozen, they can dig a ditch as a precaution." ”

"Digging a trench for prevention?" At this time, dense fireworks were lit every other section in the Yin Gou River, which was the Chu army engineer burning the frozen soil. Wang Jian was looking at these fireworks and didn't understand what Liu Chi meant.

"Yes, yes." Liu Chi nodded deeply: "The Jing people hit me with a witch weapon, and after the bullet of the witch weapon was fired, it fell and bulleted, killing and injuring our army." If our sergeants dig the ground into a ditch, the whole army will hide in the ditch, and the bullets of witchcraft will be harmless. ”

In the past few days of captivity, Liu Chi was both worried and afraid, and had nothing to do but think about how to win this decisive battle. Like the cavalry shock artillery array, some things can still be solved as long as you think about it, and for the artillery of the Chu army, he naturally thought of the trenches of later generations.

Trenches are a natural product of heavy artillery bombardment, and they do not originate from the Civil War or the Russo-Japanese War, but have an earlier history. In the 16th century, the Spaniards had already learned to dig field trenches and allow infantry to hide from French artillery fire (Battle of Ravennes, 1512), and even earlier in Italy in the 15th century, where Italian generals were adept at using field fortifications.

Liu Chi didn't say that it was okay, as soon as he said that Wang Qian's whole person trembled, he looked at Liu Chi for a while before looking down at the ground under his feet: "The earth is frozen, how can I dig a ditch?" ”

Wang Jian was a little stunned because of his excitement, and the question he asked didn't need Liu Chi to answer, and Chu Jun had already told him the answer. Knowing this, he even called someone, Liu Chi stopped him and said, "Why is the general like this? ”

"Our army dug a ditch to wait for the Jing people, the Jing people attacked, our army climbed the ditch and attacked it, why do you need the cavalry to attack the witch weapon array again! Alas, why didn't you say it sooner! The more Wang Jian spoke, the more excited he became. In order to delay the artillery fire of the Chu army, the Qin army had to place 15,000 cavalry in front of the formation to attack the artillery array, but these were solved by only one trench. "Someone! Quickly find combustible things, and then order Lifu to dig a ditch......"

Liu Chi thought of digging a ditch to avoid the artillery bombardment of the Chu army, but he didn't expect that this would save the suicidal link of the cavalry charging into battle. When Wang Jian gave the military order, he turned his mind and hurriedly said: "General, it's too late." ”

"Why not?" There was already some anger in Wang Qian's words. If he can save 15,000 cavalry, he will definitely be able to hook the back of the Chu army. The 30,000 cavalry broke through the defense of the Chu cavalry, and as described by Bai Di Taifu, they hit the back of the Chu army, and the army formation would collapse. "Hurry!" He waved his hand to let the military officials go quickly, and then he spoke to Liu Chi.

"If the general wants to dig a ditch, how deep is it, how wide is it, and what is its length?" Liu Chi asked. "Its depth is at least five feet, its width is at least six feet, and its length is at least eight miles. And our army poured the city, and the land of the sand sea was already muddy, and now it is muddy and frozen, and it cannot be set on fire until two or three days. ”

The length and width are fine, but as soon as the ditch is eight miles long, Wang Jian was deflated. He knew how the Chu army bombed the city, and the Chu army could dig holes in the city, not the entire section of the earthen embankment had to be chiseled and flattened. He knew very well that the mud in the sea of sand was now frozen, and it was indeed not something that could be dug up in a day.

"Alas!" Wang Jian sighed, but Liu Chi thought of other ideas at this time. "If you can ask King Jing to delay the war for two days in the name of the eldest son......"

"Our army is baking fire here, King Jing doesn't know?" Wang Jian pointed to the black smoke rising from the gutter in front of him, and didn't think Liu Chi's plan was feasible.

"Then dig it up at this moment, and for every mile you dig, you can hide a mile of pawns; If you dig eight miles, you can hide the pawns of the front. Liu Chi also knew that this strategy was not feasible, and the king of Chu might not agree to help Su delay the war.

The Chu army used fire to bake the frozen soil in the earthen embankment, and the Qin army dug up the snow and even baked the frozen soil under their feet. When the lookout on the nest car reported that the Qin army was preparing to dig the soil with a rake, Xiong Jing's brain suddenly buzzed, Qin Jun was going to do civil engineering work and dig trenches.
