Kong Yingda was confused when he looked at the chemical formula in front of him and couldn't understand it at all, but he still said, "Can I give me some time?"

Wang Ding nodded and said, "Don't worry."

Kong Yingda then accepted the letter.

Wang Ding returned to the palace and reported to Li Shimin: "Your Majesty, you have already handed it over to Master Kong Yingda, saying that it may take some time."

Li Shimin nodded and said nothing more.

Wang Ding said again: "Your Majesty, Lu Dongzan has entered the pass and is about to arrive in Chang'an. He said that he is rushing to congratulate His Majesty this New Year, and the envoys of the countries are on the way."

Before we knew it, it was about to reach the tenth year of Zhenguan.

Li Shimin felt a little moved in his heart that he had been an emperor for ten years.

Putting down the memorial in his hand, Li Shimin said: "When Lu Dongzan arrives, he takes the people to Jingyang, and the other envoys from the countries will be handed over to the Ministry of Rites to receive."

"I understand, but now the position of Minister of Rites is still vacant."

Only then did Li Shimin remember that the affairs of the Ministry of Personnel were handled by Li Xiaogong, and Li Xiaogong later handed them over to his son Li Chongyi.

Now Li Chongyi has gone to Jingzhao Prefecture again, and the position of Minister of Rites has indeed been vacant for a long time.

Li Shimin sighed melancholy, "Then let Li Xiaogong go."

Jingyang

Li Jiangshan has also been staring at Li Zheng during this period, but he doesn't know what Li Zheng is doing.

Since the things dug out from outside came, Li Zheng seemed to have done nothing, and the laboratory has been rebuilt, and Li Zheng has never used it.

Can't see through what Li Zheng wants to do?

The saltpeter sand that was transported was right in front of me, but since it was transported, Li Zheng had never touched them.

I came to the Jingyang River again and looked at Li Zheng who was fishing with the King of Wei from afar.

This guy is fishing so comfortable?

Li Zheng looked at the fishing line and said to Li Tai: "I recently left the village."

Li Tai looked ahead with his eyes blank and replied weakly: "Oh? What does it have to do with me?"

Li Zheng sighed and said, "Actually, it has nothing to do with His Highness King Wei, but after I left the village, I always felt that someone was following me."

Li Tai smiled disapprovingly, "That's natural. You, Li Zheng, are young and have offended many people."

After saying that, Li Tai counted, "Buddhist, five surnames, powerful people, some royal relatives, and Eastern Turkic people don't know whether Ashi is dead or alive. If he is alive, he would fight for you. There are also Songtsen Gampo of Tubo who wants to swallow you alive, and... "

"Okay, okay, you need not say anything." Li Zheng interrupted, "You always say I always feel that it is my life to go back to the village alive this time."

Li Tai patted Li Zheng on the shoulder, "What a pity, if I can be the crown prince and ascend the throne and become emperor, maybe..."

Li Zheng looked at Li Tai, "Maybe he will help me eradicate these enemies."

"Wrong!" Li Tai said solemnly: "I will chop your head to comfort the suffering of the whole world Li Zheng has been doing for a long time."

Li Zheng smiled self-deprecatingly: "It's really something you can do."

Li Tai touched his chin and said, "Li Zheng, although I am not in Chang'an now, I still have some connections in Chang'an. I asked a few days ago and told my father some time ago that it was an adult prince who left Chang'an. Many officials who advised him were more or less related to the prince."

"Fatty, I don't want to get involved in your royal affairs."

Li Tai said again: "I don't have the heart to oppose the prince now, but I can't say that I'm going to do whatever I want. Although Li Tai is honest, he can't bully honest people, right?"

Li Zheng glanced at Li Tai and then looked at the sky.

Li Tai also looked at the sky, "What's wrong?"

Li Zheng withdrew his eyes and said, "Nothing."

"Huh?" Li Tai also withdrew his eyes, and then said something wrong: "Li Zheng, do you think I'm talking lies with my eyes open, God will hit me with lightning."

"No, Your Highness the King of Wei is thinking too much."

After the two of them were quiet for a while, Li Tai stood up and said, "Forget it, let's not catch any more, all the fish in Chang'an have become energetic."

Li Tai left without any fun when he spoke.

Li Jiangshan watched this scene from afar. After Li Tai left, he watched Li Ji walk towards Li Zheng.

"I heard from Dahu that you have something to look for me."

Li Zheng said to him: "Are all the things sent to Tubo ready?"

Li Ji sat next to Li Zheng, "I knew you had a lot of things to tell me this time, just talk."

Li Zheng put the fishing rod aside and said, "I have a truckload of things next to the laboratory. These things will be delivered to Tubo at that time, and handed them to Mouu, and let him hand them to Daniu."

Li Ji nodded, "I understand."

Li Zheng continued: "There is also to let Xingxin enter Tubo, and let him find the big bull in Tubo to help Da Niu do things."

"Is there anything else?"

“That’s all now.”

Li Ji wrote down Li Zheng's arrangement in his heart, "I'll make arrangements now."

Li Ji was quite happy that the weapons business could open.

Li Zheng caught a grass carp. Fishing requires patience. Like Li Tai's temperament, he sat by the river for less than half an hour.

Carrying the fish caught, Li Zheng returned home and planned to make fish soup.

Let Xu Jingzong arrange the letter sent to Daniu. In the letter, there are chemical equations for the burning of gunpowder and the usage of gunpowder.

Only Daniu can understand this letter.

The letter was delivered to Daniu, and the raw materials for gunpowder transported with weapons were added.

Big bull can make gunpowder in Tubo.

Nowadays, the big guys have the guards of Wang Xuance and Jingyang, and the King of Shu has returned to Jingyang.

In terms of the detailed ratio of gunpowder, only the Jingyang Guards in the hands of Daniu and Wang Xuance can know.

If he handed the recipe to Li Shimin now, Li Zheng suspected that Li Shimin would kill him without hesitation after getting this weapon.

The secret recipe is completely confidential, and Li Zheng is confident that even if Li Shimin intercepted the letter he wanted to hand over to Daniu.

They also can't understand it. Chemical equations are leading the basic knowledge of chemistry in primary and secondary schools in this era for nearly a thousand years.

It's hundreds of generations away.

In addition to saltpeter, charcoal, and some silt and sand were sent out.

Only four of these materials are very important.

The rest of the things are useless and are all materials that can be seen everywhere.

These things were transported out together, and even if Li Shimin wanted to break his mind, he couldn't figure out what these things were used for.

Hearing the laughter of the little rhino outside the door, Li Zheng came to his senses and continued to kill the fish. Today he could make a bowl of tofu fish soup.

Lu Dongzan rode his horse on Longyou Road, following Tang Xuanzang beside Lu Dongzan.

Tang Xuanzang looked at the environment of Longyoudao, "I haven't returned to the Central Plains for a long time, and there is still no change here."

Hearing Tang Xuanzang's words, Lu Dongzan said, "That's the holy monk, you didn't see Jingyang."
