Sucheng really doesn't need magic weapons at hand now.

When he followed Miao Shan to the "Wuji Heavenly Lord", Miao Shan dealt with all the disciples of Wuji Heavenly Lord. At that time, Su Cheng completely took away the magic weapons that imitated the Ancient Sect in the hands of these disciples. Apart from the "Fire-avoiding Dragon Cover" that was pierced by Miao Shan, the remaining magic weapons of the Immortal Mountain, the Yin-Yang Two Qi Rope, the Desolation Bell, the Cloud Clothes and the Demon-Subduing Pestle, the Snake Escape Pot and other magic weapons were all in Su Cheng's hands.

Of course, these magic weapons are not as powerful as Lingbao, but for Su Cheng, it is enough. As for Lingbao, it should be very likely to be successful in practicing Taoism with Laojun.

After Miaoshan and Laojun's bet was completed, he also took it back to Yuqing Heaven.

Su Cheng was nostalgic, but he knew that Miaoshan could not be retained now, and in the future, there would naturally be a long life for two people.

"Brother Su, please send me a gift."

Miaoshan said softly.

Su Cheng nodded naturally, and the two of them carried their clothes and told each other with all their hearts. Su Cheng knew that Miaoshan was a gentle person, and Miaoshan also knew Su Cheng's character. The two of them moved forward step by step, reluctant to leave.

Their separation is based on years, which is too long for the two who fall in love with each other, but compared to the long and endless life span of the two, it is not long.

"Brother Su, my family master has orders, but the immortal way will never last, and we will eventually have a long time."

Miaoshan said in a warm voice.

"Take off the silk skirt and embroidered skirt, and the fairy will definitely come to the mortal world."

Su Cheng held Miaoshan and said, "Qingjing is given to Youyou Dream, and the treasure tent is born with dark spring... The next time we are together, my foundation of my immortal path has been settled, and then we..."

"spit!"

【Miaoshan】 reached out and pushed Su Cheng away and said coldly: "Dream!"

Fairy Cihang and Miaoshan are one mind. If Su Cheng and Miaoshan are intimate, she will naturally be able to perceive and clearly convey the matter to her heart. This is completely unacceptable!

"Just as long as you two have the intention, don't think about the rest!"

[Miaoshan] As he said, his figure rose into the air and left slowly. There was a hint of irritation on his cheeks that was difficult to fade.

Su Cheng looked at Miao Shan's figure until she disappeared.

After Miaoshan left, Su Cheng returned to his usual days. Su Cheng no longer cared about everything outside. He allowed Ji Meng and Ji Chao in Luoyi City to fight in the internal struggle, and he returned to the days when he used to listen to the scriptures under Laojun's door and then hurried in the library to read the Taoist sect.

"Junior Brother Su, what are these you wrote?"

On this day, Wang Fangping suddenly came to Su Cheng, holding a thick stack of paper in his hand and placed it in front of Su Cheng.

These days, when Su Cheng was reading the Daozang, Wang Fangping couldn't see what it was in the outer alchemy technique, and could not add it to the Daozang, so he came to Su Cheng to ask for advice on the contents.

"Oh, this is the simplicity."

When Su Cheng saw something on the paper, he said calmly: "The most important thing for those who practice Taoism refine essence into qi, and qi into spirit is to transform one into one, and those who use external alchemy are also transformed."

Su Cheng took the paper, pointed to the things on it, and said to Wang Fangping: "We are under Taiqing. We are practicing the first-class alchemy in this world. We have many elixirs that can be refined into external alchemy. Therefore, we naturally know what can be made into elixirs and what can not be made into elixirs. However, there are many false people in this world. The alchemy methods they practice are extremely shallow, so they use various cinnabar, gold, silver, black lead, and sulfur to mix them together to condense the elixirs. Such external alchemy will be of no benefit to eat into the human body, but it will have all kinds of harms."

Wang Fangping nodded when he heard this.

He followed Taishang Laojun to compile the Taoist sect. Many of the things in this Taoist sect were oralized by Taishang Laojun, but there were also a small part of them, which were miscellaneous books in this world, and needed to be recompiled, sorted and eliminated. In this small part, Wang Fangping saw many inappropriate external alchemy methods.

For example, gold, silver and copper pills, only those who have become immortals can swallow them. This can regulate the five qi of the whole body and have some benefits. Ordinary people will definitely die if they take them. However, the most extensive alchemy methods in this world are all made of more metal and stone and fewer herbs, which is of no benefit to people.

"What I have written is the transformation of burning elixir."

Su Cheng pointed to what he wrote and said to Wang Fangping: "Look at this scripture, this person said that he used lead to make lead powder and lead elixir..."

Lead pills are mostly used for medicinal purposes at this time.

At this time, lead powder is mostly used in pottery production, and women apply faces, and some aspects are also medicinal.

"What I am writing here is the process of the change of lead to lead powder and lead elixir."

Su Cheng pointed to the other side and said, "Lead powder is alkaline lead carbonate, and lead elixir is lead tetroxide. This is their production process..."

Since the last time he taught Wang Bao how to rescue disasters and taught the poor to grow fungi, he has gained some merits, Su Cheng has always wanted to make another profit, but he did not want to go out and get stuck in the matter. When he accidentally read Daozang, he found a way.

No matter how good the Taoist philosophy is, it is undeniable that when Taoism was passed down, many people died because of the alchemy method, and even some emperors died because of superstitious elixirs and swallowed too much.

Therefore, when Su Cheng saw the alchemy method of some alchemy scholars in the Taoist sect, he couldn't help but get in mind and explain it on the alchemy method, so that people can truly understand the physical properties and chemical properties.

This will also be the basis for people to explore higher levels.

"For example, this cinnabar burns into mercury, and the mercury accumulates into cinnabar."

Su Cheng pointed to this sentence and said, "The previous sentence is a process of cinnabar mercury extraction..."

There are also various alums, such as alum, alum, yellow alum, and bile alum, which are all sulfates.

The alchemy of folk alchemists is actually like the pioneers of later experiments. They also included the changes in the process of burning the alchemy, and accumulated a lot of people's understanding of nature. However, after the chemical changes and physical properties of Sucheng appeared, they could avoid this detour.

“Are all that you said useful?”

Wang Fangping frowned and asked after hearing Su Cheng's words.

After listening to Su Cheng's explanation, Wang Fangping already knew the meaning of the name Su Cheng said, such as lead tetraoxide. Under the perception of the immortal, he did not need any instruments at all. He could see the microscopic changes in this directly, so he naturally knew that the name was very appropriate.

But Wang Fangping didn't think there was any meaning in it.

"It's just that people understand the world, and they also help people avoid wrong paths in external alchemy."

Su Cheng looked at Wang Fangping and smiled and said, "Senior Brother, just include all of these and classify them in the method book. This is also a trivial contribution I have made for Daozang."
