Just as Wu Weiyi and Du Yu were talking on the city tower, they heard someone hurrying up the city tower. When the man arrived at the city tower, he saw that the princess and Wu Weiyi were talking about something, so he wanted to wait on the side first.

The two turned around and saw that it was Mo Zhai, and Wu Weiyi called to him:

"What's the matter? But it doesn't hurt to say that. ”

Mo Zhai saw that Mr. Wu opened his mouth and asked first, so he immediately replied:

"Mr. Wu, the Jingma River is now dammed into a lake, if you want to do it, you can do it immediately!"

It turned out that as early as when Wu Weiyi first arrived in Picheng, Mo Zhai had discussed with Wu Weiyi, saying that a small dammed reservoir could be built in the upper reaches of the Jingma River, which could be used for the defense of Picheng on the one hand, and on the other hand, it could also reduce the danger of river flooding during agricultural time.

Wu Weiyi thought that this plan was feasible, so he asked Mo Zhai to lead people to the upper reaches of the Jingma River to fill the river and build embankments.

I saw Wu Weiyi step forward again and whispered to Mo Zhai and asked:

"Are the bamboo rafts all ready? Have all the gates been carefully inspected? Also, is your newly invented Moon Dam really capable of keeping the flood out of the city? Are you sure? ”

Mo Zhai listened, but saw that he patted his chest and said:

"Mr. Wu can rest assured that everything has been arranged, and I have told the skilled craftsmen to assist at all the city gates, and to ensure that every city wall is tightly fitted and solid! As for the Shuiguan Moon Dam...... Mr. Wu can also rest assured, although he has never tried it, it stands to reason that there will be no mistakes. ”

Wu Weiyi nodded, then turned to the princess and asked:

"Princess, now that the damming of the Jingma River has become a flood potential, it can open the flood gate at any time, and the Shu master stationed here can be flooded in an instant. As for when to do it, I still ask the princess to decide. ”

When Du Yu heard this, he couldn't help but feel a shock in his heart:

"Sir, do you want this? …… The water of the Ma River flooded the Shu division of Dujiang?!...... It's a clever idea, but it's ...... The water outside the city will inevitably pour into Picheng, and at that time, what should happen to this Picheng? ”

I only heard Mo Zhai sneering on the side, and said to the princess:

"Princess, relax, my Mo Zhai has lived with the uncles in the clan since he was a child, and under the influence of his ears and eyes, he also has some experience in making instruments. When Mo Zhai first came to Picheng, he found that Picheng was low-lying, and the Jingma River was suspended between the mountains, so it would be a big disaster if the river flooded. Therefore, some time ago, I mobilized the craftsmen here to set up a set of water gate moon dams for each of the four gates of Picheng. When there is no flood, the sewage flow from the city can be discharged outside the city as usual, and once the flood hits, the Moon Dam will immediately block the flood water from entering the city, preventing the flood water from flowing through the sewage pipes and causing backflow. ”

Du Yu was stunned when he heard this:

"Is there such a strange tool in this world? What kind of 'water pass' alone can save Picheng from flooding? It's unheard of! Brother Mo Xiaoxian, if you have such superb skills, you will definitely be able to achieve something in the future. ”

Mo Zhai listened to the princess's unhesitant praise, but he didn't like it at all, but said in a serious euphemism:

"The princess praised me falsely, my Mo Zhai was just a slave, thanks to Mr. Wu's refusal to abandon me, treat me like a brother. Moreover, Mr. Wu is a great sage in the world and understands righteousness. Now I have no other wish, but I hope that from now on I can always be by Mr. Wu's side, help the justice of the world, and help the people of the world. If this can be done, Zhai's wish will be enough."

The princess looked at Mo Zhai's loyal and honest appearance, and couldn't help covering her mouth and nose with one hand, and laughed out loud:

"Hey, it seems that the position of this chief disciple of Mr. Wu, this palace can't snatch this Mo Xiaoxian brother? But it doesn't matter, this palace has always been elegant, so let you, the chief disciple, be ranked! ”

Wu Weiyi naturally heard the meaning of Du Yu's words, but Wu Weiyi himself could no longer understand it clearly. In the final analysis, he Wu Weiyi is not in the same era as these people after all, sooner or later, he will leave after all. Moreover, Wu Weiyi also knew very well that the Zoroastrian Fire God Sect he was facing now could be described as having deep roots, and being an enemy with it was by no means a one-time achievement. If you want to overcome the dangers and finally achieve the restoration of the order of time and space in the future, and return to the future, it can be said that every step in the future will be extremely dangerous. If it's just Mo Zhai following him, then it's okay, after all, this Mo Zhai is a generation of Mo family giants who will start a sect in the future, so it doesn't matter if he follows him. But Du Yu is just a weak woman, and she is the princess of Shu. So she can't be implicated in any case!

Thinking of this, Wu Weiyi respectfully said to Du Yu:

"Hehe, the princess laughed, how could Wu accept the princess as an apprentice. The princess is kind and benevolent, and she will need the princess to preside over Shu in the future to protect the peace of the Shu country. Wu was originally a wanderer, and he wanted to say goodbye to the princess after all. ”

The princess seemed to feel a little sad when she heard Wu Weiyi's words, but she also knew that it was not beneficial to dispute these at this time. So he stopped talking about it, but deliberately led the topic out:

"Hehe, let Mr. Wu smile, this palace is just joking, Mr. Wu doesn't have to be so nervous. Anyway, since Mr. Wu has everything ready, this palace can also relax. It's just that...... There is still one thing to ask for in this palace. ”

"I don't know what? The princess said that it didn't matter, as long as Wu did what he could, he would definitely share the princess's worries. ”

Du Yu nodded, but his face was solemn:

"Since Mr. Wu is trying to divert water to flood the enemy, it will be very tragic outside Picheng at that time. Every time this palace thinks of the thousands of dry bones at the foot of Qingcheng Mountain yesterday, this heart is always at peace. Therefore, I just hope that Mr. can try to save as many Shu sergeants here as possible, these sins are all caused by Du Jiang, the elder brother of the palace, and these Shu people are innocent. If he buried the lives of tens of thousands of Shu soldiers in vain because of his sins, this palace really can't bear it. Besides, for these Shu soldiers, if they lose their lives in vain, there is no fairness at all! ”

As soon as Du Yu's voice fell, before Wu Weiyi could speak, Mo Zhai showed off and replied to the princess:

"Hehe, the princess can rest assured, Mo Zhai has been taught by Mr. Wu for a long time, so he naturally knows the truth of 'too much', and he must have a scale for doing things. On several occasions, I have inspected and measured the valley and the landscape of the valley here, using the light and shadow of the sun to measure the height of the mountain and the amount of water in the damming of the Jingma River. But when the lake poured into this valley, the deepest part of which was only a foot deeper, it should make them cowardly, but it should not cause them to die or injure them too much. ”

Du Yu listened to Mo Zhai's countermeasures with such confidence, and this was the real letting go of the boulder hanging in his heart. Then he said with concern to Wu Weiyi:

"Mr. Wu has also been running around with the palace for a long time, and I ask Mr. Wu to take care. The palace went to discuss with Zijuan about the evacuation of the people in the city. Tomorrow, when the people in the city have settled down, the palace will arrange for them to withdraw to the high ground in the city, just in case. At that time, the gentleman can open the sluice gate and release the water to ward off the invading enemy. When the fighting subsides, we will discuss the matter of going to the country of Yelang for refuge. ”

After that, Du Yu walked all the way down the city tower accompanied by the maid, and then got into the carriage and galloped away.

At this time, on the top of the city tower, only Mo Zhai and Wu Weiyi were left, and when Mo Zhai saw the princess walking away, he began to joke with Wu Weiyi playfully:

"Hehe, dare to ask Mr. Wu, are you really confused or pretending to be confused? I, Mo Zhai, didn't understand it at all. ”

Wu Weiyi heard Mo Zhai ask like this, but instead he was confused, and he didn't know what Mo Zhai meant by this.

What did Brother Mo Zhai mean by this? I really don't understand? ”

Mo Zhai shook his head and sneered:

"Are you all so unkind? The princess has made it clear that she already likes you, but you are still pretending to be stupid here? I, Mo Zhai, have fled all the way to this point, and I can be regarded as having served more than a dozen masters, but there is no heroine as gentle and virtuous as Princess Nishikori. If you can marry a wife like a princess, what more can a husband ask for! ”

Wu Weiyi was told by Mo Zhai, and his face was immediately flushed, and he was ashamed. I didn't know how to answer for a while.

"Mo ...... Don't talk nonsense! Virtuous Brother...... I think you're only twelve or thirteen years old now, but why are you so busy? What do you understand? ”

When Mo Zhai heard this, he was quite unimpressed, and continued to answer with Wu Weiyi:

"Sir, don't say that I'm still young and unqualified. In fact, I can see many things clearly. An older man like Mr. always looks far-sighted, but many things seem to be blindfolded. As everyone knows, how can there be the best of both worlds in this world? If people's hearts are insufficient, the snake will swallow the elephant, and after all, it will be burdened by it! It's better to talk about things on the basis of the situation, and be at peace with the situation, but on the contrary, you can end up at ease. Sir, do you say yes or no? ”

Wu Weiyi was speechless by this Mo Zhai for a while, and secretly thought in his heart:

"It's really worthy of being a person who will start a sect in the future, and this kung fu is really comparable to ordinary people."

Thinking of this, Wu Weiyi also had nothing to say, just shook his head with a wry smile, and said to himself:

"Hey...... I really don't know when this catastrophe will come to an end! If it's a dream, how can it be so real? ...... I'm afraid, I'm afraid, in the end, it's just a dream......"
