Lu Di nodded, the water was besieged, and Lu Di didn't know when he would be able to break out of the encirclement, so the sergeant's water must be careful to prevent large-scale diarrhea or even plague. After all, in this battle of Zhengdu, the corpses of the dead soldiers did not have time to be completely cleaned and buried in the ground.

So from a distance, you can still see floating corpses of soldiers everywhere in the water from time to time.

"No matter what, you have to leave this place as soon as possible, no matter what the cost" Lu Di patted the female wall and said to the generals behind him.

"No"

Two days later, the three veterans of Jing, Guan, and Sandi, Gongsun Jie, Tian Kaijiang, Gu Yezi, and Qi Guo got the news that Lu Di was trapped by the flood in turn.

This news was naturally conveyed by Xinying.

The three generals were stunned at first, and then secretly happy, because they finally had a place to use.

These three armies stationed on the south bank of the Great River were originally intended to prevent a sneak attack by South Korea, but now because South Korea is completely mired in a big war with Zhao, the three armies are not of much use.

The three generals immediately beat the drums of war and gathered the generals, preparing to return to the army to rescue Lu Di.

According to the strategy explained in the secret letter, the three generals led the army to detour westward, sneak attack the back road of the Wei army, destroy the land, and then divide the troops into three routes, and then besiege the secret city of the Wei army's grain and grass land one after another, forcing the Wei army to withdraw from the city, so as to ensure the safe breakthrough of the main force of the Qi army.

The Great Tent of the Wei Army's marching commander was located on a huge raft, surrounded by countless small rafts, each of which had Wei soldiers sitting or standing, wiping weapons, or napping and resting, as if bees were maintaining their nests.

Wang Xu walked out of the marching tent and was about to stretch his waist, in order to plan and succeed in this battle, he was really tired. At this moment, a Wei general hurriedly came here on a raft.

"Prime Minister, it's not good, the Qi army sneak attacked our army's grain storage place, the secret city"

General Wei hadn't jumped on the raft of Wang Xu's military tent yet, and when he saw Wang Xu, he couldn't help but scream.

Wang Xu was slightly stunned when he heard this, the Qi army secretly attacked the secret city where the Wei army's military food hoarding was located? How can it be? Aren't the Qi armies all besieged in Yidi? Where did it come from? Could it be that Lu Di deliberately got it to trick me into retreating?

Wang Xu fell into deep thought, and after the Wei general jumped on the raft, he saw that Wang Xu was silent, thinking that he had not heard his own shout, so he repeated it again.

Wang Xu said lightly: "Oh, how did you learn about this?" ”

Yan Yan carefully observed the Wei general.

Na Wei hurriedly handed over what he had gotten to Wang Xu, and then explained the situation before and after.

It turned out that the Wei general was idle, and when he saw a falcon hovering in the sky, he had the desire to hunt, so he picked up a longbow, bent the bow and shot an arrow, and by chance, shot a falcon, and after scooping up the falcon from the water, he found that the falcon was tied with a cloth silk.

The cloth silk is naturally a silk letter written by the three veterans of Qi to Lu Di, the letter said that the army has been ordered to assemble, and it will definitely live up to the expectations of the king, and within half a month, the land and the secret city will definitely be taken by our army. King Wang, no matter what, will hold on for another half a month.

Wang Xu looked at the water-soaked letter, his brows furrowed, is this true, or is it a deliberate ecstasy trick by Lu Di and Sun Wu to induce him to withdraw from the army?

There are two kinds of people in this world, one is the person who sees the mountain is the mountain, and the other is the person who sees the mountain is not the mountain, the person who sees the mountain is the mountain lives simply and happily, and the person who sees the mountain is not the mountain lives a painful life.

But even this kind of nerve-wracking and painful living people still think that they are superior to others.

Wang Xu and Lu Di belong to the latter, if you show him a mountain, he thinks that the mountain is not a mountain.

Was it a trick or is this really the truth?

The more Wang Xu thinks about it, the bigger his head becomes, he can make decisions quickly for others, but for Lu Di and Sun Wu, he doesn't have this confidence, after all, everyone is a smart person, who would make such a low-level mistake?

"General Ren, what happened?" Xiang Lu also jumped on the raft at some point, and when he saw Wang Xu in a daze, he couldn't help but ask the general next to him strangely.

General Ren is also the Wei general who bent the bow and shot the eagle before to report that the Qi army was going to sneak attack the land and the grain and grass hoarding.

When General Ren saw Xiang Lu, he hurriedly clenched his fists and explained.

For this hunchback Xiang Xu, General Ren did not dare to slack off, although Xiang Lu did not have a title and official position, but he still did not dare to offend, one Xiang Lu is Wang Xu's disciple, and he General Ren is a five-body surrender to Wang Xu, the so-called love house and Wu is also; Second, there are rumors in the palace that Xiang Lu is about to become the master of the little prince, with Xiang Lu's talent and connections, that is, the future minister, of course, it is more likely to be a supplementary minister.

Therefore, combining these two aspects, General Ren will be respectful when he sees Xiang Lu.

Wang Xu only woke up from his thoughts at this time, and he handed the letter to Xiang Lu and asked him to see if he could find some clues. Xiang Lu quickly glanced at it, thought for a while and said: "Master, the disciple suggests that the commander immediately attack the city, if you can't take it within three days, you should immediately withdraw the troops, and ambush on both sides of the road before the reinforcements of the Qi army arrive in the secret city."

"As long as we eliminate the reinforcements of the Qi army, even if we lose all the land we have seized from Zheng and retreat back to our own country, in fact, we will win."

"Because of this battle of alignment, we are not for Lu Di's life, but for the defeat of Qi and the contradictions in other countries."

Xiang Lu's words were loud, Wang Xu slapped his forehead, and suddenly woke up, in the game, he almost forgot his original intention, and scolded himself for being confused!

Then the Wei army mobilized, and an offensive against the army began.

Will the Qi army be able to withstand this attack?

Tens of thousands of rafts attacked the water-soaked city at the same time, which was spectacular, and the rain of arrows in the sky harvested the dense life gathered on the city wall. At the same time, rows of stone-throwing trucks, throwing stones, smashed into the attacking Wei army.

The battle lasted until dusk, and the number of dead on both sides was uncountable. In the end, the Wei army did not break through the city wall and returned in despair.

Lu Di watched the Wei army retreat on the water, and his heart did not cheer like others, because he knew in his heart that if this city wall was soaked in the water for a few more days, he was afraid that it would collapse directly.

The city walls of this era are all mud walls, although Lu Di invented bricks when he was a child, but that kind of thing is not something that can be used casually, not to mention, the technology of burning bricks has been strictly controlled by the Qi domestic government, and there is no rumor, although Zheng Guo has money, but in order to build such a large and thick city wall, he can't afford it, and he can't afford it, and he doesn't have his own brick-burning factory, so he can only have the traditional soil method to water the city wall.

The so-called soil method of watering the city wall, that is, first use the wooden mold base, make a wall, and then pour the soil into the mold base to form an independent soil mold base wall, and then cover a large amount of firewood on the soil mold base wall, ignite it with fire, and wait for the firewood to burn out, the mold base burns out, and the earth wall is built.

It is said that this method of watering the earthen wall was invented by Fuxi, which is very ancient and vicissitudes, but it can be used in a long history, and I have to say that this method of watering the earthen wall is still very good, otherwise it will not be recognized by time.

This kind of earthen wall is usually very strong, but once it is flooded, the earthen wall will be finished, and it will soon collapse.

The walls of Yidi are all earthen walls, which cannot withstand the soaking of heavy water at all, and the Wei army deliberately destroyed the key parts of the earthen wall before leaving, so the collapse of the earthen wall is even faster.

"Reinforcements must come soon!" Lu Di said silently in his heart.
