Follow him to a wine shop in Chang'an.

After sitting down, Xu Jingzong asked the clerk to serve a plate of mutton and some dried fruits, and then two pots of Cheng's spirits.

Li Chongyi looked at Xu Jingzong's expression and said, "Brother Xu doesn't seem to be in a good mood today."

Xu Jingzong nodded, "I did encounter some troubles, and I don't understand what Chang'an Ling is thinking."

Li Chongyi nodded and said, "Li Zhenshi has a strange temper."

Xu Jingzong took the drink handed over by his friend and said, "Maybe I am thinking too much."

Li Chongyi said: "The strange people in this world always have some incomprehensible temperaments, and Li Zheng is the same."

Xu Jingzong looked at the file on Li Chongyi's waist curiously and asked, "Why did Young Master Chongyi bring this?"

Li Chongyi ate a piece of mutton and took another sip of wine and said, "A very strange thing happened today."

Xu Jingzong smiled and said, "Some strange things have been happening in Chang'an. Just say, the day when Princess Changle got married, who can explain the strange phenomena in the night sky clearly."

Li Chongyi put the file out and said, "Please also ask Brother Xu to look at this file."

Xu Jingzong took the file and opened it and took a look, and returned it to Li Chongyi without hesitation.

Li Chongyi took back the file and said, "Brother Xu, this file is very strange, right?"

"What's weird? It's just a business of a temple man."

"But he redeems himself."

Xu Jingzong drank wine and said, "That's even more normal. Isn't it normal to redeem himself for himself? How many women in Pingkangfang redeem themselves every month?"

Li Chongyi glanced around, and the winery was very noisy, and he whispered: "The Changsun family suddenly wanted to check a temple man who redeemed himself. Is it strange to say it's strange?"

Xu Jingzong still said calmly: "Maybe this temple man offended the Changsun family."

"Is that true?" Li Chongyi drank suspiciously hastily

Xu Jingzong smiled and said, "We will drink today and don't talk about these troubles."

Li Yifu picked up the wine bowl and said, "Okay, I won't talk about these troubles today."

After a pot of strong wine was eaten, Li Chongyi stood up and said, "Thank you, Brother Xu, for treating me to wine today."

Xu Jingzong smiled and said, "You're welcome."

After helping Li Chongyi to Jingzhao Mansion, Xu Jingzong left Chang'an.

The Changsun family asked Jingzhao Mansion to investigate the things that were satisfactory.

Xu Jingzong was confident in this person.

Even if the Changsun family found this person to be satisfied with?

Even if I feel satisfied, I don’t know anything. If I vomit silently, it’s fine.

I am satisfied with this person, and it is so clean that it makes people feel at ease.

The Dali Temple Minister left Chang'an and was no longer the Dali Temple Minister, and not many people paid attention to it.

Walking very low-key.

Xu Jingzong stood at the entrance of Dali Temple, and a guy who bought naan bread walked away with a smile and said, "Xu Tou, it is said that the weapon case is full of fame."

Xu Jingzong casually picked up the naan bread from this man’s stall and ate it and said, “Is that so?”

The guy said, "Didn't Changsun Chong go to guard Yumen Pass? I wrote a letter a few days ago that he found the man who sold weapons, and he was called Xuxin."

Xu Jingzong was eating naan bread, "You continue."

The guy whispered: "It's a pity that this soothing is now Songtsen Gampo is now a distinguished guest in Tubo. The man from Changsun is now talking to Songtsen Gampo of Tubo to discuss whether he can hand over Suothing to the court. He found the real murderer of the weapon case. Unexpectedly, he was in Tubo, and Prince Changsun made a great contribution."

"I caught a Turkic man in Dali Temple before and thought that the Turkic man was the one who bought and sold weapons. Now the truth is revealed. It turns out that the one who satisfies me."

As he heard that Xu Jingzong was eating naan bread, and before drinking with Li Chongyi, he only ate a few slices of mutton.

However, this time I was found out, and it was safe to vomit silently.

I felt a little glad that I didn't kill me at that time.

Otherwise, once Suixin is arrested, the business will be terminated.

At least there is still a silent vomiting now.

Did Chang'an Ling have long thought of this level?

If it is said that Chang'an Order's magic trick, can even calculate this?

The guy said again: "Tao Xu, how is this news? Not many people know about it now."

This guy is also one of the reporters of Jingyang Magazine.

Jingyang Magazine has a lot of reporters, all of which are from all walks of life.

All kinds of news were also learned from the people of all religions and ranks.

Is it really a great achievement to find out that Changsun Chong was satisfied?

Xu Jingzong sneered, maybe Changsun Chong is still complacent now.

Your Changsun Chong made contributions, but he cut off His Majesty's current wealth path.

"I am really a child of a noble family who is ignorant of the world." Xu Jingzong said disdainfully.

"That's it! If the current queen hadn't been the Changsun clan, where would his Changsun Chong have come from? Chang'an people say that Changsun Wuji relied on his sister to become Duke Zhao."

Xu Jingzong handed the guy a piece of silver cake and said, "Go and check it more,"

After half a month of seclusion, Li Zheng finally walked out of his house and began to plan to build a dam.

This project is very large, and site selection is also a very critical factor.

There are three benefits of building a dam, which can adjust the water volume of a river, form a reservoir, and form a water level difference to provide water power.

The dam in Jingyang does not need to be too large, just a water level difference of about one meter high.

It is obviously unrealistic to want to build a large dam that is the same as later generations.

Pei Xingjian also noticed Li Zheng who was watching the river with the drawings.

After walking forward in a small step, Pei Xingjian bowed a little and said, "Teacher."

When Li Zheng looked back, he saw Pei Xingjianru, who is now fourteen years old.

I came to Jingyang with Xue Rengui.

He and Xue Rengui are fellow townsmen and are both from Hedongdao.

Pei Xingjian asked, "Teacher, are you measuring the river channel?"

Li Zheng withdrew his gaze and said, "I plan to build a building in the river."

Pei Xingjian followed Li Zheng's gaze and said, "If you build a house above the river in front, it will easily collapse because the soil is too soft."

Li Zheng looked at Pei Xingjian in surprise.

Pei Xingjian then said: "Students think it would be better to be in some places upstream."

Of course, Li Zheng knew that the upstream river channel was better, and the upstream river channel was wider than the downstream, so that it could better store water and create a water level difference.

But the upstream river channel is not the territory of Jingyang.

Li Zheng handed the drawing to Pei Xingjian and said, "Look at this drawing."

Pei Xingjian took the drawings with both hands and looked very polite.

Carefully spread the drawings on the ground. The drawings are very large, more than three meters wide and five meters long.

This is also the result of hard work reading these days.

For the printing press for mechanical kinetic energy.

My eyes are almost myopia, and I have been reading books all the time.

Pei Xingjian looked at the outline on the drawing and asked, "Teacher is going to block the waterway upstream?"

Li Zheng explained: "I call this a dam, a building that controls water flow."
