Xu Jingzong was still a little worried, "I think I still have to be careful. If something happens, it will probably affect the Chang'an Order."

Seeing that Li Zheng was still looking at the book, it seemed that he didn't care so much.

Maybe Li Zheng never regarded Changsun Chong as an opponent and did not take the Changsun family seriously.

That's what I think.

Xu Jingzong said again: "I wrote to you that Persia has been very uneasy recently, and Dashi and Persia have fought."

"Dashi and Persia?"

"Yes, it is said that the Persian prince has asked for help from Tubo and Western Turks."

"Songtsen Gampo should really want to win over the ally of Persia."

Xu Jingzong nodded, "The letter does say that the Persian prince and Songtsen Gampo have been very close these days."

Persia was indeed very strong during the Northern Wei Dynasty, but it began to decline during the Sui Dynasty.

During the Zhenguan period, the Dashi period had already begun to have the idea of ​​an Eastern Expedition.

In less than thirty years, the food in Persia was calmed down.

Many Persian nobles fled to Tochar.

The next twenty years will be a very chaotic era in the West.

Persia, India, Western Turks, Tochar and India will all enter a melee.

Perhaps this is another huge business opportunity.

Xu Jingzong looked at Li Zheng's expression suspiciously, "Why does Chang'an Ling laugh?"

Li Zheng came back to his senses and said, "Hey, did I laugh just now?"

Xu Jingzong whispered: "Chang'an Order smiles like this every time he sees silver cakes."

Li Zheng sighed, "Actually, I am not a person who loves money. You all misunderstood me."

Xu Jingzong said skeptically: "Is that true?"

Dai Zhou, the minister of Dali Temple, came to the village outside Jingyang and saw His Highness King of Jin and a group of children planting trees.

The wasteland that could not have been planted with food now looks green at first glance.

I thought in my mind that there are now several unsolved cases, weapons cases, ghost fires burning Chang'an, temple collapses, and strange phenomena in the night sky not long ago.

He is so old that he originally wanted to retire.

But now there are several unsolved cases.

I don't know what's wrong with this world.

I always feel that I just can't get along with myself.

The most questionable person is Li Zheng.

But there is no evidence.

Seeing that King Li Zhi of Jin had also rested, Dai Zhou walked up and said, "Your Highness of Jin, are you planting trees?"

Li Zhi looked at the old man in front of him, "You are the minister of Dali Temple, I have seen you before."

Dai Zhou stroked his thumb and said, "I wonder if His Highness King Jin can speak with one step?"

Li Zhi greeted Daniu and others and followed Dai Zhou to the distance.

Li Zhi looked at Dai Zhou and said, "I don't know what the Dali Temple Minister has to give."

Dai Zhou smiled and said, "I haven't seen you for many years, Your Highness King of Jin has grown so tall."

Li Zhi grinned and said, "I have eaten a lot recently, and the teacher's cooking skills are very good."

"His Highness King Jin's teacher? Li Zheng."

"Yes."

Li Zhi nodded and said.

Dai Zhou nodded slightly, "Since His Highness, King Jin, is a disciple of Li Zheng, I guess he is very close to Li Zheng."

Li Zhi looked at Dai Zhou in confusion and said, "I live in the teacher's house now."

Dai Zhou whispered: "Have Li Zheng made any strange moves recently?"

"A weird move, what weird move?"

Dai Zhou sighed and said, "Some unsolved cases have been reported in Chang'an recently. I have found some clues."

Li Zhi said: "Dali Temple Master is suspicious of the teacher?"

Dai Zhou whispered: "It's just a suspicion. Of course, I will definitely make a case impartial."

Li Zhi thought about it and said, "If the teacher does something strange, it will be true."

Dai Zhou nodded and said, "What's the move?"

Li Zhi whispered: "Recently, the teacher has read books every day, neither fishing nor taking naps anymore, saying that he wants to learn more knowledge to increase the output of Jingyang Printing Bookstore."

“Knowledge? Yield?”

"right."

Dai Zhou fell into deep thought again. Is this matter related to weapons?

It seems that there is no connection.

The big bull's shouting came from a distance. When Li Zhi realized that he was going to class, he hurriedly said, "I only know this. I'm going to go to class even if it's time."

Dai Zhou came back to his deity and said with a smile: "I'm disturbing His Highness, King of Jin."

Li Zhi bowed and said, "Goodbye."

After Li Zhi left, the smile on Dai Zhou's face froze.

Walking towards the village in Jingyang, there are a group of spies from Dali Temple looking for clues.

Saltpeter, charcoal, sulfur, these three things are in the collapsed temple, and the night sky vision not long ago.

These fragments were found around the temple, and they were also found on the bamboo tubes on the ground after the vision.

Dai Zhou couldn't figure out what the relationship between these three things was, but it can be concluded that it must be artificial.

Otherwise, it wouldn't be possible that such a thing would happen so much.

"Report!"

The spy from Dali Temple came to report: "Report! We found someone transporting saltpeter on Jingyang New Road."

Hearing this, Dai Zhou hurriedly said, "Save people, I will go and have a look."

Li Zheng also gave the newly built pipeline a name called Jingyang Xinlu.

Hello everyone, our public account will find cash and red envelopes every day. You can get it by following it. The last benefit at the end of the year, please seize the opportunity. Official account [Book Friends Camp]

It's really strange that someone else would name the road.

On the new road in Jingyang and looking at the lively scene here, a group of officers and soldiers from Dali Temple stopped a group of civilians transporting saltpeter at the intersection.

"No one is allowed to leave when investigating the case in Dali Temple!" Some officers and soldiers from Dali Temple drank.

Dai Zhou came to the scene, and there was a car full of saltpeter.

"I am the Minister of Dali Temple. What do you want to do with such saltpeter?" Dai Zhou asked.

"So it's the Minister of Dali Temple, who is rude and rude." A group of kids immediately changed their previous rebellious expressions, but they only eased a little.

Dai Zhou looked at them and said, "I asked you, what do you want these saltpeters to do?"

"We are the army of General Cheng Yaojin's family. The saltpeter was transported to Chang'an to make ice. I don't know how this incident disturbs Dali Temple."

Looking at the expressions of the few people, Dai Zhou assigned two officials from Dali Temple and said, "You go to Chang'an with them to see if this is the case. The Cheng family's saltpeter must be approved by Dali Temple when it is used in the future."

"Here!" Several officers and soldiers from Dali Temple bowed and agreed.

Dai Zhou thought that there were actually a lot of saltpeter in Chang'an, and it took huge manpower to take care of all these saltpeters.

And it may be that the other party will continue to use these saltpeters to commit crimes.

There is no clue at all. Salter can make ice. Since Li Zheng's use of saltpeter has come out.

More and more people use saltpeter to make ice in summer.

The weather in Chang'an is a little hot in May.

Summer will begin in two months.

Then more people will dig saltpeter.

How can I investigate this case?
