An Lai left, Li Hong called Zhou Xing to his side and asked, "Zhou Xing, is this errand still going well?" ”

"Back to Your Highness, I have done this errand very well, and I also like to deal with torture instruments very much." Zhou Xing said happily. He used to just like the law, but now that he has come into contact with these torture instruments, he has fallen in love with them after playing with them again. At the same time, a strange idea also popped up in his mind, that is, what kind of effect would be the effect of changing these torture instruments?

"If you like it, do it seriously, and when you win the imperial examination this year, I will recommend you to go to Dali Temple." Li Hong said, "If you want to play with torture instruments, Dali Temple is a really good place." ”

The Dali Temple Prison in the Tang Dynasty is full of felons, and many times interrogation has become a technical job, seeing that Zhou Xing likes torture so much, Li Hong doesn't mind putting him in Dali Temple. Li Hong's secret guard just lacks a master of torture, if Zhou Xing is polished for a few years, and then recalled to the East Palace to entrust him with a heavy responsibility, let him and Wei Chi Xunyan take charge of the secret guard together, it is a good move.

Although Li Hong trusts Wei Chi Xunyan very much, how can there be a situation where one person dominates the secret guard system? Although Yan Zhuang is part-time, it is difficult to control the situation because of many things, and the person who can contain Wei Chi Xunyan in the future, Li Hong feels that only Zhou Xing is the only one who can contain Wei Chi Xunyan.

"Thank you, Your Highness!" Zhou Xing said overjoyed.

What he likes is not that the prince said that he recommended him to serve in Dali Temple, but that the prince said that he would recommend him to Dali Temple if he was promoted, isn't this telling himself that he will definitely be able to win this year?

In fact, with Zhou Xing's current age and knowledge, as long as he polishes for another two years, he can go to the dark guard to serve, and there is no need to take the road of the imperial examination. But Li Hong didn't think so, the large-scale popularization of books would promote the progress of the imperial examination, and after he solved the problem of Tibet, the next plan was the imperial examination, he wanted to change and enter the imperial examination system, and wanted to improve the chances of the children of the poor family taking the scholars.

Therefore, for the sake of Zhou Xing's future, he felt that Zhou Xing must pass the imperial examination in order to have a better future.

After Zhou Xing left, Li Hong returned to the East Palace. When he left the palace this time, he missed Zhou Juan very much, but he didn't go to her again. Because he was afraid that looking for Zhou Juan too often would cause dissatisfaction among Gaozong and Empress Wu.

As for whether Gaozong and Empress Wu knew about his every move, Li Hong's answer was that they were very clear. The reason why he didn't point it out in front of him was because he didn't do anything out of line. If you go to Zhou Juan three times and twice, it is estimated that Gaozong and Empress Wu will not be able to stand it.

As soon as Li Hong returned to the East Palace, Yan Zhuang came to see him and said that he had spread the news to the mansions of the two princes. Li Hong nodded slightly after listening, he held this dog fighting competition just to give Li Xian and Li Zhe a warning. Everyone is a brother, and speaking too obviously will hurt the harmony, and it will also make Gaozong and Empress Wu dissatisfied, so you can only convey your meaning in this way.

After Yan Zhuang finished reporting, he still stood in the study and did not leave.

Li Hong asked, "Do you have anything else?" ”

"Your Highness, Prime Minister Xu sent someone to send an invitation, and I want to invite you to his mansion for a banquet in the afternoon." Yan Zhuang said, "I don't know how to reply? ”

Xu Jingzong invited himself to the banquet, this is the first time!

Li Hongwei thought about it, then nodded and replied, "You just said that Gu is going to visit in the afternoon." ”

Yan Zhuang was slightly surprised, the prince had never taken the initiative to participate in the family banquet of the ministers, this was the first time, could he have said anything? However, seeing that after the prince said this, he ignored him, and Yan Zhuang didn't dare to ask again, but bowed down and exited the study.

Yan Zhuang left, and Li Hong began to write and draw in the study again.

Yesterday, the drawings he handed over to Yan Zhuang were about the process of steel smelting in the late Ming Dynasty, and now Datang can only smelt raw iron, and then forge and decarburize pig iron, or use wrought iron into a furnace to heat and carburize into steel. Li Hong's smelting process yesterday was the method of frying steel. It is to connect the iron-making furnace and the iron-frying furnace in series, so that the molten pig iron smelted by the iron-making furnace flows into the iron-frying furnace, and stirs it with a willow stick to oxidize the carbon in the molten pig iron and mature the iron. Steel can be produced without the need for cooling and reheating, reducing fuel consumption and significantly increasing production.

Then with the new technology of smelting steel, iron ore has become a big problem. Abundant iron ore can support the smelting of the volume and the steel needs of Datang. Therefore, what Li Hong did today was to follow his memory to see if he could find a few good iron mines in Datang.

Of course, his ambition is not so small, since he can find iron ore with the memories of his previous life, can he also find a few gold or copper mines?

Li Hong thought while drawing a picture with his memory, and marked the place name on the map.

After a short time, he marked several place names, namely Liaodong and Liaoxi, Chengde, Tangshan, Zhangjiakou and Jiaojia, Xincheng, Yinan, Rushan and other places. These places are rich in gold in history, and the names marked by Li Hong are different from the place names in the Tang Dynasty, so they need to be revised again. Then the locations of several historically famous iron mines were also marked by him and written on paper.

After writing these two pieces of paper, he put the paper marked with iron ore and the paper from the gold mine on the table separately, and called Yan Zhuang into the study.

"Yan Zhuang, clean up, let's go to Xu's Mansion for a banquet." Li Hong said.

"No!" Yan Zhuang was ordered to leave.

Li Hong put the paper marked with the distribution of iron ore in his sleeve.

Mining iron ore is not his strong point, and besides, his dignified prince mines iron ore privately, and he has a bad reputation. He is ready to hand over this task to Xu Jingzong, Xu Jingzong loves money, he must know the profits here, and Xu Jingzong is the prime minister of the Tang Dynasty, let him mine iron ore, it will be much cheaper in all aspects. Another point is that Xu Jingzong is not a disciple of the gate lord, and if he cooperates with Xu Jingzong, he will definitely take the lion's share and have more right to speak.

When Li Hong and his entourage arrived at the gate of Xu's mansion, they saw Xu Jingzong leading the people of the mansion to greet him at the door. Li Hong exchanged a few words with Xu Jingzong, and then followed Xu Jingzong into the gate of Xu's mansion.

The Xu Mansion covers a large area, and the decoration is very yellow, even Li Hong, who is used to living in the East Palace, walked into the Xu Mansion and was attracted by the magnificence in front of him.

Xu Jingzong saw that the crown prince was surprised when he saw the decoration of his mansion, so he smiled faintly, "The old minister has no preferences, just such a little interest, but it makes His Royal Highness smile." ”

"Xu Xiang said that when you go there, people work hard all their lives, isn't it just to eat well, drink well and live well?" Li Hong said. Xu Jingzong nodded slightly, because Li Hong's words were very appetizing to him.
