Li forgot to worry, rubbed his hands and said with a smile, "uncle, I have an unkind request, too. Old immortal sun wants to trial produce penicillin, but he needs to make a microscope first. Hey hey, can uncle order the craftsman who will be the supervisor to help me make a microscope?"

Li Er glared at him: "you need to cooperate with the craftsman as the supervisor. You can go to Yan Lide. I don't know if you let the craftsman as the supervisor to help you build the vending machine in recent days?"

Li forgets worry a little embarrassed. He lets the craftsman who will be the supervisor do private work. Unexpectedly, Li Er knows about it.

He touched his nose: "Hey, uncle, it's mainly to build telescopes. It needs a lot of high-quality crystals..."

Li Er replied angrily, "OK, I know. I'll ask Shangshe bureau to send you some crystals later."

In Sui and Tang Dynasties, there was no imperial internal Treasury in the imperial palace. There are only six bureaus and twenty-four departments responsible for the management of Court Affairs.

Shangshe bureau is the Department in charge of palace furnishings and travel tents. Most of the crystals are used as furnishings and naturally belong to Shangshe Bureau.

Li forgot to worry and asked Li Er for crystal. Naturally, it was not that the crystal given by Sun Simiao was not enough, but that he thought of many other good things because of the microscope, which could be polished with crystal.

That's why he took this opportunity to ask for more. He can also use the public for personal gain and get some other novelty by the way.

After talking about penicillin, Li Er Cai put his attention back on Li Chengqian.

"Ziyou, can you send Chengqian back to Xiande hall for cultivation now?"

Li forgot to worry and shook his head: "uncle, it's better to let Chengqian rest in this palace. After all, I've detoxified this place with alcohol, and the chance of Chengqian's wound infection is less."

"In that case, it's up to you. But..." Li Er paused and looked at the people in the hall: "but no one can confide half a word about today's matter. I don't want the prince's intestines to be cut off and make a storm all over the city."

Everyone understood what Li Er meant.

After all, it's ridiculous for Tang people to cut people's intestines.

If this matter is spread to the outside world, it may damage the crown prince's reputation.

Everyone naturally bowed down and promised not to spread it. As for the eunuchs in the East Palace, they all knelt down in fear, kowtowed repeatedly, said they were very strict, and swore that they would not leave to reveal any news.

These internal eunuchs often see such things in the palace.

In the palace, the best way to shut them up and keep secrets is to turn them into dead people!

A dead man will never reveal a secret.

Even though Li Er is an enlightened king, he may not be kind to these palace servants.

At the moment, when he looked at the internal attendants, he seemed to be thinking about whether to summon the guards and drag them out and kill them.

Li forgets to worry and sees the internal attendants kowtow like garlic. He can't help but feel unbearable: "uncle, Chengqian still needs to cultivate here for some time and need someone to serve him. These internal attendants are a little hard today. Let them continue to serve Chengqian here."

Hearing the speech, Li Er thought about it and nodded slightly: "in that case, it's according to what you said."

As soon as he said this, the eunuchs felt that they had narrowly escaped death and did not dare to say more. They just knocked a few heads in the direction of Li forgetting worry, and then got up and retreated to one side silently.

"Uncle, Feng Yu and the doctor from Shang medicine bureau probably know how his nephew treats Chenggan. Can they keep it a secret?" Li forgets to give eye medicine to Geng Hong and others.

"It's no problem. They won't believe it if they haven't witnessed it with their own eyes. I'll let the palace guards seal off the palace. No one is allowed to go in and out except you until Chengqian recovers completely."

"Promise!"

Empress Chang sun and Li Tai talked with Li Chengqian for a long time before Li Er persuaded them to go back. And Li Chengqian was naturally left in this palace for cultivation.

Li Qieyou, Sun Simiao and Liu Shenwei also temporarily stayed in this palace to take care of Li Chengqian. After dawn the next day, the beauty boss returned to Dingzhou village to appease the old housekeeper Li Heng and others.

Li Er asked the guards to block the palace in the east palace. He didn't mention Li Chengqian's condition, but it caused a great storm.

There is no secret in the east palace.

Even in this Tai Chi palace, there is air leakage everywhere. Whenever there is a disturbance, I'm afraid Li Er can spread it to the outside world as soon as he knows it.

The prince was suffering from intestinal carbuncle. He was terminally ill and was in danger. At dawn the next day, it was known to all officials in the court.

In this regard, all officials have different reactions.

Those who worry about the life of the crown prince worry about the crown prince's death and whether the newly established crown prince can inherit the throne. After Li Er blocked the news of the East Palace, all kinds of rumors flew around. No one could figure out what happened to Prince Li Chengqian.

Even a hundred officials speculated that the prince had died, but it was just that Li Erhi was not lost.

The aristocratic family headed by five surnames and seven hopes suddenly felt refreshed and felt that they had pinched Li Er's painful feet.

In the Zheng's residence in Xingyang, a banquet was held as usual this night. Several aristocratic family owners hid in the elegant room and whispered.

"Prince, is the news from the palace true? Does Li Chengqian really have intestinal carbuncle?"

"Yes, there is no doubt about this. I asked Feng Yu of Shangyao Bureau and several doctors who diagnosed Li Chengqian. They all confirmed that Li Chengqian was suffering from intestinal carbuncle."

"Tut Tut, in this way, there is no doubt that Li Chengqian will die?"

"I think so. I've asked many famous doctors. There's no cure for intestinal carbuncle. Let alone a yellow mouthed child like Li Chengqian, who is determined not to survive."

"I heard Geng Fengyu say that the little bastard surnamed Li is said to want to open Li Chengqian's belly and treat intestinal carbuncle. Isn't it true?"

"Ha ha, Prince, do you believe such absurd words? If you can cure people by cutting open their stomachs, is it not da Luo Jinxian who came down to earth?"

"Ha ha, yes, that's it."

"But in this way, once Li Chengqian dies, it's worth our good operation. The last time I let Li Shimin's man escape through the so-called Taoist ancestor's holiness. I'll see how he gets away this time."

"Duke Lu, Duke Cui and Duke Wang, to tell you the truth, I have ordered someone to get in touch with the supreme Emperor..." in the elegant room, Zheng Yuanshou lowered his voice and whispered with several aristocratic family leaders.

The candlelight burning in the elegant room threw several people's figures on the wall, which looked particularly ferocious
