For Chen Hui, it's a very simple thing to configure drugs that can make people feel feverish and weak. It doesn't take much time.

Even Chen Hui can prepare it the first time he goes back.

However, Chen Hui still spent some time. After several experiments, he made a kind of pill from a bronze tripod according to his own formula, and let the pill melt in water.

Of course, the first thing Chen Hui did when he returned to his residence was not to immediately study the combination of this medicine, but to completely hide the tunnel entrance leading to the palace of the king of the Mu nationality and the bedroom of the Qing emperor.

Two days later, Chen Hui had prepared the medicine, and the Qing emperor sent someone to call Chen Hui into the palace.

The people sent by the Qing emperor were the officials in the imperial palace. They didn't ask the wizard who drew Chen Hui in to take him into the palace as before.

However, this news can not be concealed from the wizard who wooed Chen Hui.

On the way to the palace, Chen Hui saw the wizard who drew him in. They nodded their heads tacitly, which was a kind of greeting.

There is no doubt that this time Chen Hui was summoned to the palace by the Qing emperor, he must have watched the process of alchemy.

In fact, it is true. After Chen Hui entered the palace, the Qing emperor took Chen Hui to the alchemy wizard, the location of alchemy.

There is a special room for alchemy in the Imperial Palace, and the room is only used for alchemy. The alchemy will be kept by the Qing emperor. No one knows where the alchemy made by the Mu clan is.

Danfang is not only one house, but a row of houses.

"The sorcerers in the capital city of our clan have very low level of cultivation. They are not up to the level of alchemy!" Standing outside the alchemy room, the Qing emperor explained to Chen Hui, "some of the Wizards in Hengcheng are not up to the level of alchemy, only a few of them are in Hengcheng. When they reach the level of alchemy, they also choose the way of alchemy, but they can only go back to the Royal city to alchemy!"

Hearing this, Chen Hui nodded silently. This is the basic information of the wizard who is responsible for alchemy.

At this time, some alchemists came from a distance and walked into the room.

After they met the emperor, they simply saluted him with their fists. Without saying anything, they went into the danfang.

It can be seen that the relationship between the Qing emperor and these alchemy witches did not pay much attention to such things as etiquette.

It can also be understood that the Qing emperor's management of these alchemy witches was quite relaxed.

"Most of the alchemists are those who can really calm down and study alchemy." At this time, the green emperor said: "therefore, I will not have too much to say to them, to them, to me, and to other people, and I will not take other people's thoughts into consideration."

Hearing this, Chen Hui understood that the witches who chose the way of alchemy were all those who were really learning in the world he came to.

This kind of people often have very high IQ, but their EQ is average, and some even have very low EQ, because they devote all their energy to alchemy.

Only by focusing on one thing can we do a good job. This is an eternal truth.

"Why did you take so long to prepare for alchemy?" Chen Hui asked at this time.

The so-called long preparation is only relative to Chen Hui, because the Qing emperor had already told Chen Hui that he had to watch the process of alchemy, but it had been delayed for so many days.

"Not long, actually." The green emperor replied: "every time the alchemy, all the alchemy wizards will alchemy together. The raw materials they need must be prepared completely. They can start alchemy only once they have alchemy. Basically, they keep the frequency of alchemy once a month."

At this time, smoke came out of one of the danfang. The green emperor pointed to the danfang, walked forward and said, "let's go in and have a look!"

Chen Hui followed the emperor and entered the danfang. He was stunned.

Because Chen Hui saw a very familiar object, bronze tripod!

If Chen Hui didn't know that the bronze tripod was on him, he would think that the bronze tripod in the room was his own!

"Is this what alchemy uses?" Chen Hui pointed to the bronze tripod and asked.

The green emperor nodded and said, "this is the cauldron for alchemy!"

"Can I come and have a look?" Chen Hui asked at this time.

The Qing Emperor gave up his body and naturally indicated that Chen Hui could watch it up close.

The bronze tripod in this danfang is not very big. Its diameter is about one meter. It is not directly placed on the ground. Instead, it is supported by stones under each tripod. The height of the tripod is just level with the chest.

Among the three stones supporting the three legs, another stone slab was connected. On this stone slab, firewood was burning. The smoke from the danfang was formed by the burning of firewood.

Chen Hui went over to have a close look and found the difference between this bronze tripod and the magic weapon he used. This bronze tripod has no pattern, and the whole body has no pattern. He can't see it clearly at the door because the tripod is covered with a thick layer of soot under the constant fire of alchemy. He can't see whether it has any pattern.

Chen Hui looked into the bronze tripod and found it empty!

Chen Hui stepped back, pointed to the bronze tripod and asked, "there is nothing in it!"

"It's still on!" The Qing emperor explained: "before alchemy, the furnace must be opened first. That is to say, wood is used to heat the cauldron body first, so that the materials left by the last alchemy will disappear through the heating of the cauldron body!"

"I see!" Chen Hui said with a sudden look.

At this time, there was a very slight sound outside. Chen Hui turned his head and looked out. Many warriors appeared around the row of danfang and surrounded the row of danfang.

"Every time the alchemy is done, the warriors will be responsible for guarding it and killing it if they are close to it." Qingdi light said.

"Is this the rule of alchemy, or is it?" Chen Hui didn't ask what he said. Obviously, he wanted to ask the Qing emperor whether it was always such a rule or whether the Qing emperor set such a rule.

"This is the rule of alchemy." Qingdi explained.

Chen Hui nodded in silence, with the help of a warrior and the presence of the Qing emperor in the imperial palace. Even if the Qing emperor was not here in the danfang, the secret of the wood family's Alchemy would not be revealed.

At this time, the alchemist of the danfang went to the cauldron furnace and put his hand into the cauldron furnace!
