Whether Wang Zhen could have predicted that the Persians wanted a method to refine black oil, this was answered in the affirmative when Birus found Wang Zhen and told him the results of their discussion and Wang Zhen directly threw the only thick envelope on the table to Birus.

"Inside the envelope is what you want, which is the latest technology from the Tang Dynasty. It can not only guarantee the oil yield, but also ensure safety during the refining process.

After obtaining the secret method, arrange large-scale production as soon as possible, and then find a way to sell it as quickly as possible and exchange it for food. Although there are not many people in the whole of Persia, the post-war resettlement is not an easy task.

Regardless of whether it is in accordance with the Tang Dynasty law or the people-oriented philosophy of our Yuzhou clan, resettling the people has always been the most important thing, and its priority is even higher than war. "

Bilus smiled like a child while holding the thick envelope. With this thing, life would be much better for everyone in Persia in the future. After all, lighting has always been an indispensable thing in people's lives.

Persian black oil is everywhere, and it can be said to be a very profitable business. The only drawback is that Persia is too far away from the mainland of the Tang Dynasty, and it is also by land. Otherwise, if the black oil could be sold to the Tang Dynasty, it would be considered prosperous.

After all, the Tang Dynasty not only had a large population, but was also extremely wealthy, and had many good things. If there were a lot of them going back and forth, it would be truly incredible.

From now on, Persia will implement Tang law. Everyone, including you, the Grand Commander of Persia, will be subject to Tang law. Therefore, you must use Tang law as a guideline when doing things. The most important thing is to keep yourself clean.

Wang Zhen nodded and said, "Not only Nan Sheng, you can also find more young people in Persia to learn Tang law, and then assign them to Xu Zheng. After all, the power of law enforcement will be returned to you sooner or later."

Wang Zhen nodded, looked at Bilus with a serious face, and said, "There are two more things I must tell you first.

Baloch could accept the tax on black oil alone. After all, a country has many ways to collect taxes. Although black oil is important, a 30% tax would not cause much impact on Persia. So Baloch agreed to the first condition without hesitation.

After leaving the Tang army base, Bilus went to find Nan Sheng first, wanting to discuss the issue of law enforcement power with his sister, but was told that Nan Sheng had gone out.

Xu Zheng smiled and nodded, saying: "Teacher taught me that war is only a means, and the ultimate goal must be to make people live a good life. With the means of our Yuzhou system, it is not difficult to win any war. Destruction is not a skill, only construction is a real skill.

Bilus himself was not sure whether he could manage the group of noble officials in Persia and make everyone act according to the Tang laws, so he directly agreed to Wang Zhen's proposal, but also sent Nan Sheng, who was familiar with the situation in Persia, over.

Bilus breathed a sigh of relief. He had originally thought that Wang Zhen would use Tang natives to enforce the law, which would increase the resistance of the Persians. Since a large number of Persians were involved, it didn't matter. So he nodded and smiled, "That's no problem. That's great."

It would be difficult for these people to ask them to strictly abide by the law.

It is only now that I understand why you brought more craftsmen and students to Persia than soldiers."

At this time, Nan Sheng was standing on a small hill, staring at the city below in a daze. Xu Zheng was standing beside him with a smile on his face. Not far behind them were their respective guards.

It just so happens that Xu Zheng has a lot of experience in law. As early as when he was in Yuzhou, he specialized in studying law. When he was in the Western Regions, I also gave him the power of law enforcement."

Wang Zhen looked at Bilus's embarrassed expression, raised his eyebrows and said, "If you feel it's too harsh, you can hand over the law enforcement power to me first. After a few years, I will teach you Persians how to abide by the law and what awe is, and then I will return the law enforcement power to you.

Especially when it comes to corruption, you must not touch it, otherwise, there will be no room for maneuver.”

On the contrary, it was the second request that made Bilus feel a little harsh. After all, Persia had nobles. Although these people had lived in disgrace over the years, their lawless character had not changed much.

Second, all Persian officials are Persians. This is our agreement, and His Majesty has also agreed to it. There is nothing to argue about this, but I hope you can explain it clearly to those Persian officials.

When Wang Zhen mentioned the resettlement of the people, Bilus patted his chest and assured cheerfully: "Don't worry, General Manager, no one wants to resettle the Persian people as soon as possible more than I do. I will make arrangements as soon as I return."

Bilus thought about it, nodded and smiled, "I know this, okay, then I will give him the power of law enforcement, and let Nan Sheng be Xu Zheng's deputy, so that they can spend more time together and get to know each other better."

“The people in your school are really capable. These refugees have only been brought back for more than ten days, and they have basically walked out of the shadow of the war. It’s just that the money and food supplies have been consumed too quickly, but they are still doing well.

First, black oil is a civilian material as well as a military material, so 30% must be deducted as tax, 10% for military use, 10% as national tax, and 10% as salary for the Tang Dynasty support personnel.

As for the matter of money and food, you don't have to worry too much. Our current logistics will be able to support us for three to two months. As for the future, I believe your brother has already obtained the secret method of refining black oil from Second Brother.

With black oil, there is always a place to exchange for various emergency supplies. Not to mention that the people from the Tang Dynasty are already on their way to Persia, even the craftsmen and students we brought with us this time, as long as there is land and manpower, the problem of food and clothing in Persia will no longer be a problem in a year. "

You have to know that this was an era when the land was vast and the population was sparse, and the population of Persia was only a few million. There was a large area for planting and grazing, so the problem of food was still easy to solve. After all, the Yuzhou family was best at people's livelihood.

Nan Sheng nodded and said, "I have never doubted this. After all, a school of thought that can write an encyclopedia cannot be unable to solve the problem of food and clothing.

What makes me curious is, is your school good at divination? Why can you always guess what we discuss here?"
