In the Governor's Office, Sun Zikong delivered all the tools he found to Chu Huan's study as Chu Huan's instructions. The outer hall of the study was quite spacious. Chu Huan was carefully checking the tools Sun Zikong was looking for.

When Sun Zikong came in from outside the courtyard, he was holding a very small cloth bag in his hand. When Chu Huan arrived next to him, Chu Huan turned his head to look at him and asked, "Have you taken it?"

Sun Zikong handed over the cloth bag, "Master, this is taken from the kitchen, and this is the salt used in the kitchen."

Chu Huan took the cloth bag and opened it. Soon he saw yellow-brown crystals appearing in front of him. The number was not large. Chu Huan pinched one and licked it with the tip of his tongue. There was a salty smell at first, but in addition to the salty taste, it was mixed with other strange flavors, which made Chu Huan frown.

"Is this the salt we use on weekdays?" Chu Huan looked at the yellowish-brown crystals in the cloth bag, a little incredible, "Do we eat these things every day?"

Sun Zikong didn't know why Chu Huan was so interested in salt today, so he nodded and said, "Master, this is the salt we eat every day, the salt in the kitchen, and it was sent by Mr. Su and the others. Now that Xiguan is short of salt, the kitchen also said that all these salts should be saved. Unlike in Beijing, there is no shortage of salt, so the taste of the dishes may be lighter... They said there is no way. They have been to the market, and salt is difficult to buy, and the price is expensive. Mr. Du temporarily manages the accounting room. According to the previous rules of his wife, the daily consumption of the kitchen is strictly stipulated and cannot be used openly. In the past, buying a pound of salt in Beijing, the same price is five or six times higher, and there is no market price... So the kitchen can only save salt...!"

Chu Huan smiled bitterly and said, "I'm not saying that the kitchen uses more or less, I just... I just think the quality and taste of the salt seem to be too bad, right?"

Sun Zikong looked into the cloth bag and said, "It's worse than the salt in the capital, but it's much better than other places... Master, there are not many people who can use this kind of salt now...!"

Chu Huan then handed the cloth bag back to Sun Zikong, "Go to the kitchen." Sun Zikong took the cloth bag and was about to leave. Chu Huan thought about it and finally said, "Don't leave first."

"What are the instructions for the master?"

Chu Huan pointed to a brown stone with whiteness and said, "Carry the hammer and smash the stone into the yard. The smaller the better... the thinner the better..."

When Sun Zikong saw that the stone weighed at least ten pounds. He found it as Chu Huan ordered, he said a little embarrassedly: "Master, I...I'm not very strong, I'm afraid it will take a while. If you use it urgently, I'll find someone with great strength to come over and quickly smash the cold stone into small stones..."

Chu Huan waved his hand and said, "We should not be known to others. I can trust you so I told you to do this. Don't talk so much nonsense."

Seeing that Chu Huan looked very serious, Sun Zikong didn't dare to say anything, so he went over and picked up the stones and went to the yard, then went back to the house and picked up the big hammer. Chu Huan had already said: "The cold stones are not the same as ordinary rocks. They look very strong, but they are much fragile than real rocks and can easily break. You can't take much time..."

When Sun Zikong began to smash cold stones in the yard, Chu Huan began to set up the hand-cranked stone mill that Sun Zikong had found in the house.

As Chu Huan said, the toughness of the cold stone is much weaker than it looks. Every time Sun Zikong smashes it, a piece of gravel will spread out. Chu Huan didn't wait long. A piece of cold stone that weighs about ten pounds was smashed into pieces by Sun Zikong, all of which are small particles. They use things to hold gravel and send it to the house. When Chu Huan saw Chu Huan put all the tools neatly.

Chu Huan looked very mysterious, so she asked Sun Zikong to take the hand-cranked stone mill to start grinding, while he poured the cold stone particles into the grinding eyes.

Sun Zikong looked confused. If he hadn't known that Chu Huan had always had a reason for doing things, he would have thought it was Chu Huan's prank, something was hard to grind, so he had to find a stone to grind.

Soon, the brown stone powder slowly overflowed from the edge of the stone mill, and Chu Huan collected it carefully. When the stone powder was collected almost the same, he put all the stone powder into the prepared wooden barrels in advance.

Add water to the wooden barrel and stir it with a stick, and the stone powder begins to melt into the water. The originally clear water gradually changes color.

While Chu Huan handed the wooden stick to Sun Zikong, asking him to continue stirring, and he pulled another wooden barrel over it. The barrel was covered with a double layer of linen. Chu Huan looked at Sun Zikong. Sun Zikong was smart enough to put down the wooden stick, picked up the wooden barrel filled with water, and poured the water quality of stone powder in the barrel into the wooden barrel covered with linen.

Soon, the water in the bucket was completely poured out, and Sun Zikong said in confusion: "Master, what are we doing?"

"Filter." Chu Huan said lightly: "Remove impurities inside..."

Chu Huan's explanation is equivalent to Bai Shuo for Sun Zikong. Sun Zikong doesn't understand what the so-called impurities are, and he doesn't know why he needs to remove impurities.

He just saw that there was a layer of gray-brown residue on the linen at the mouth of the bucket, densely packed with residue. Seeing that Chu Huan had removed the linen from the mouth of the bucket, he looked at the wooden barrel and found that the water quality in the barrel was already brown, much lighter than the previous color.

Chu Huan held his chin, as if he was talking to himself: "It's not enough, it needs to be filtered, the impurities inside have not been completely removed..."

Sun Zikong could only follow Chu Huan and filtered it several times in a row. When there was almost no residue on the linen cloth and the water in the bucket gradually turned light red, Chu Huan smiled and said, "Then it's time to get rid of the poison... If it's not, it's not eaten." After taking a huge funnel that had been prepared long ago, Sun Zikong was instructed to smash the charcoal that had been prepared in advance, and then put the charcoal particles into the linen cloth. The linen cloth was wrapped tightly and stuffed into the funnel.

Sun Zikong saw that Chu Huan had to filter it with a funnel, and couldn't help but say, "Master, this linen wraps charcoal and puts it in the funnel, and it's blocked inside. Can it still be used?"

At this time, Zheng Zheng fixed the funnel to the rack, and did not look back, and fixed it carefully, whispering: "What can't be passed is the dross, and what can be passed is the absolute essence..." He looked into the wooden barrel, and there was still half of the bucket of water, and told Sun Zikong to put the clean wooden barrel that he had never used under the funnel. Then he explained to Sun Zikong: "The water in the bucket is poured into the funnel, the speed should be very slow this time, don't worry..."

Sun Zikong and Chu Huan had been struggling for a long time, but didn't know what to do. Chu Huan seemed to say just now that he would not be able to eat it if he didn't take it away. He was really surprised and wondered if Chu Huan had been tinkering with it for a long time to make something edible, but this is a stone, no matter how much he tinkering with it, it cannot be made into food.

Sun Zikong carefully poured the already sticky solution in the bucket into the funnel. Chu Huan squatted under the funnel and stared at the leak of the funnel. After a while, he poured the light red solution into the funnel from the bucket. After filtering it again on the charcoal linen, a light green solution flowed out of the leak.

Chu Huan breathed a sigh of relief.

He already knew at this time that if nothing unexpected happened, his experiment would definitely be successful. The light green solution that flowed out in the end was something he wanted to get with all his efforts.

After Sun Zi Kong's half of the bucket of water came down, no solution flowed out of the funnel. Chu Huan knew that the residue was all in the bun and it was really blocked. He had prepared a bun with charcoal and stuffed it into the funnel. This time, Sun Zi Kong poured out all the water in the bucket, and the wooden barrel under the funnel had also caught half of the bucket of light green solution.

Chu Huan poked out a finger, stuck on the solution, put it in his mouth, closed his eyes, as if he was tasting some delicious food, and soon raised his mouth, opened his eyes, stood up, and said, "You can make a stove..."

A stove was prepared in the house and a pot that was not too big was set up. Sun Zikong hurriedly set the fire, and Chu Huan poured the light green solution into the pot, then put the lid on the pot and ordered: "The fire cannot be stopped, it will keep burning..."

Sun Zikong naturally did not dare to disobey. Sweat was already oozing from his forehead. Chu Huan stretched his waist, but felt a little sore in his waist. He knew that it would be cooked for a long time and said, "You burn here first. Without my instructions, you can't open the lid of the pot... Also, even if you remember what we did just now, don't say a word to the outside world for the time being, otherwise..." He raised his head and made a gesture of slashing his head. Sun Zikong shivered, but he felt that Chu Huan was making a big deal out of the matter.

Sun Zikong didn't think anyone would try this strange trick. After working on it for a long time, he still didn't know what the purpose was.

Chu Huan had already entered the study room, closed the study room door, and was about to take advantage of the gap to practice the Dragon and Elephant Sutra.

Chu Huan has broken through the third path of the Dragon and Elephant Sutra and transformed the Du, Ren and Chong three paths of the eight extraordinary meridians. When he first practiced the Dragon and Elephant Sutra, Chu Huan did not know that the essence of this martial arts lies in transforming the eight meridians and rebuilding a physical body that ordinary people cannot match. Now that the three meridians have been transformed, Chu Huan naturally understands what is going on. After Luo Duo helped him break through the Pure Land Path and transform the Chong meridian, Chu Huan has been attacking the fourth treasure elephant path.

The first three ways: practicing qi, refining bones, and practicing skin. Chu Huan knew the mysterious benefits. He wanted to know what kind of benefits he would gain when he transformed the belt meridian and broke through the Baoxiang Dao?
