Zhen Cheng soon knew that Yao Lao Weishenme was going to throw himself out and fall into the hot spring ditch, and before Zhen Cheng had time to think about it, his stomach told Zhen Cheng Weishenme.

Zhen Cheng felt as if his stomach was on fire, and the fire was burning and swollen uncomfortably.

"Huh-" As soon as Zhen Cheng's head came out of the water, he couldn't help but spit out a burnt taste, mixed with the smell in his body, Zhen Cheng was very suspicious that he had some bad breath.

When his stomach was empty, Zhen Cheng felt uncomfortable with his weakness; Now that his stomach is full, Zhen Cheng has an urge to die.

"Whoa-whoa-whoa-"

Yao Lao didn't let Zhen Cheng run out of the ditch, which was very reasonable, and when his stomach was uncomfortable, the best way was to run and digest it.

Herbs are planted on both sides of the ditch, and there is no place to run at all.

The depth of the ditch is one and a half meters, the width is less than two meters, and the bottom of the water is quite smooth, Zhen Cheng's face, like a hen about to lay eggs, is red and purple, and he keeps running back and forth in this long ditch.

A small waste pill gave Zhen Cheng the feeling that he was eating a big pot of rice, and his stomach was stretched out big and bulging.

Zhen Cheng felt an uncomfortable desire to die, watching his belly grow a little bigger, but there was nothing he could do.

"Puff-grunt-grunt-grunt-"

There was a muffled sound, and a series of blisters appeared behind Zhen Cheng, and Zhen Cheng felt a lot more comfortable all of a sudden.

"It's okay, I can fart, so I can't die!" Zhen Cheng felt that his sense of smell was numb, and he couldn't smell the smell of stinky farts, and he wondered that the smell of stinky farts was almost the same as the taste of exhalation in his mouth.

After a fart, Zhen Cheng was much calmer, speeding up, and with the help of the resistance of the water, he kept running around digesting the damn waste pill.

"Zhen Cheng, you are a pig, how can you swallow the amount of food in a day?!" The more Zhen Cheng thought about it, the more angry he became, and scolded himself loudly.

"Even if you eat it, you have to eat it with ginseng leaves wrapped in pills, that can slow down the speed of expansion! How could I forget such a simple truth? Zhen Cheng recalled everything just now with great annoyance, and gradually understood the reason why Yao Lao was angry.

There must be a special way to eat such a special breakfast, Yao Lao hasn't told how to eat it, he is as impatient as Zhu Bajie and eats the waste pill, there is no death, it is already considered creation.

Thinking of death, Zhen Cheng thought of the historical stories about the pill.

Many of the deaths of the emperors of Huaxia were because of pills, and the most singable and weeping of them was the Tang Dynasty of Huaxia.

In the 290 years from the establishment of the Tang Dynasty to its demise, there were a total of 21 emperors.

Of these 21 emperors, at least five died because of poisoning with pills: Tang Taizong, Tang Xianzong, Tang Muzong, Tang Wuzong, and Tang Xuanzong.

A Ming lord like Tang Taizong, although he was able to establish the most powerful empire in Shijie at that time, he was killed by a small "pill", and even his descendants repeated the same mistakes.

In his later years, due to a serious illness, he took the "medicine of prolonging life" refined by Zhongtianzhu Fangshi, which caused his condition to worsen and died, at the age of 50; Xianzong of the Tang Dynasty was also a good emperor, and he tried to prosper in the Tang Dynasty, but when he was in his 40s, he searched for remedies for immortality, and finally he was poisoned by taking pills and could not go to court for several months. Although Zuihou was killed by the eunuchs, if he was not killed, he would not have lived long.

After Tang Muzong ascended the throne, he punished the priests who refined the pill for Xianzong, but later he repeated the mistake of taking the pill and died of poisoning at the age of 30; After Wu Zong took the pill, the poisonous fever was unbearable, his temper became moody, and he could not speak for ten consecutive days before he died, and he was only in his 30s when he died.

Tang Xuanzong was a relatively accomplished emperor in the late Tang Dynasty, known as "Little Taizong". After he ascended the throne, he immediately killed and exiled the Taoist priests Zhao Guizhen, Xuanyuan Ji and others who poisoned Wuzong with Jindan. But then he also began to take the elixir. Due to the poisoning was too deep, an abscess grew on his back, zuihou, and Xuanzong set foot on the Huangquan Road with the poison of Jindan.

In addition to the above five, there were several Tang Dynasty emperors who were also obsessed with pills. Tang Gaozong once took pills in the second year of Kaiyao; In his later years, Wu Zetian took the pill of Taoist priest Hu Huichao; Tang Xuanzong also ordered Taoist priests to watch alchemy in Songyang, and after the Anshi Rebellion retreated to the emperor, Xuanzong still remembered the matter of burning the elixir in the golden stove; Wenzong of the late Tang Dynasty also took pills, but after he took the golden pill refined by Zheng Zhu, his condition improved, but there is no history to examine, I don't know if it is true or not.

The tragedy of the Tang Dynasty also continued to the Qing Dynasty. Yongzheng was an emperor of the feudal dynasty of Huaxia who died of pills.

When Yongzheng was not the emperor, he became interested in pills.

He once wrote a poem "Burning Dan": "Lead sand and medicine, pines and cypresses surround the cloud altar." The furnace transports yin and yang fire, and the power is both internal and external. It can be seen from this that Yongzheng had considerable research and interest in alchemy in his early years.

After Yongzheng became the emperor, he strongly admired Zhang Boduan, the patriarch of the Jindan faction, and named him "Ziyang Zhenren", and Yongzheng especially praised Zhang Boduan for inventing the essentials of Jindan. Since the fourth year of Yongzheng, Yongzheng has often eaten a kind of pill called "Jiji Dan" refined by Taoist priests. From his comments on Tian Wenjing's performance, it can be known that he felt that it was effective after taking it, and he also rewarded the elixir as a gift to Ortai, Tian Wenjing and other ministers.

According to the archives, from the eighth year of Yongzheng to the thirteenth year of the five years, Yongzheng successively issued 157 orders to deliver the items needed for alchemy to the Old Summer Palace, including 234 tons of coal for alchemy alone, in addition to a large number of mineral products such as silver, red copper, black lead, and sulfur.

"Whoa! Real TMD pervert! Zhen Cheng kept turning back and running, while thinking back to some of the pill allusions he had learned from Miao Siren, and the more he thought about it, the more angry he became.

"The old immortal, what a pervert, don't eat rice and wheat, take pills! Even if you take pills, you should eat some finished products, right? Isn't it harmful to eat waste pills? ”

Zhen Cheng finally understood that Weishenme was so polite just now, he didn't eat it, let himself, and told himself that he was full. With Yao Lao's familiarity with the properties of medicine, he will definitely not eat waste pills.

The more Zhen Cheng thought about it, the more angry he became, but he ran faster and faster, watching the herbs on both sides of the ditch continue to retreat, and doubts rose in Zhen Cheng's heart.

With my own understanding of pills, it seems unrealistic to simply use medicinal materials for alchemy, right?

In the high-risk prison, Miao Siren and the High Poison King collected thousands of classics on medicine, Zhen Cheng did not believe that the prescriptions of the classics collected by the entire Huaxia Kingdom would be fewer than those of the old medicine.

Whether it is "Thirteen Prescriptions of Surgery" or "Huaxia Alchemy and Pills", the pills recorded in it are not simply refined with medicinal herbs.

In the second part of "Huaxia Alchemy and Pills", Zhen Cheng clearly remembers that the book describes the typical pills in the three unique internal types of mercuric chloride, mercuric sulfide, and mercury oxide.

At the same time, the book also describes the promotion of Dan, the reduction of Dan, and the burning of Dan, and more than 140 Dan prescriptions in the four types of Dan, which are classified into categories by teacher, friend and related literature, and a brief table is attached to each type of Dan prescription for reference.

In the trivia after the compilation, some trivial questions are explained one by one, and readers can quickly appreciate the preparation and application of the pill after reading.

Zhen Cheng is no stranger to pills, although he doesn't know how to make them, but Zhen Cheng still likes to read this kind of miscellaneous books.

In the most authoritative "Dan Materia Medica" in Huaxia, it also talks about the composition of Danyao, oxides, sulfides, chlorides, sulfates, carbonates, silicates, arsenides, other compounds, and non-metallic products, including more than 60 kinds of inorganic drugs.

"Could it be that the alchemy mastered by Yao Lao can only use medicinal materials? Could it be that the medicine is so old that the pill is not a mineral pill, but a medicine pill? Zhen Cheng frowned, puzzled.

Among the knowledge of pills that Zhen Cheng knows, pills are a synthetic medicine based on minerals in medicine.

Alchemy originated very early in our country, about the time of Emperor Wu of the Han Dynasty, when the monk Li Shaojun "turned dansha into gold" as a eating and drinking vessel, that is, smelted the golden pill.

Wei Boyang of the Eastern Han Dynasty wrote "Zhou Yi Shen Tong Deed", using yin and yang to discuss Jindan, and was known as "the king of the ancient Danjing".

Ge Hong of the Eastern Jin Dynasty summarized the Wai Dan that circulated at that time, wrote the book "Hug Pu Zi", divided the Wai Dan into three kinds: Shen Dan, gold liquid, and gold, and called Jin Dan as medicine, the longer it is burned, the more wonderful the change, the more refined it will not disappear, and it will be immortal for the whole day, and people will not die if they take it.

In general, the pills are some heavy metals and minerals, and do not have the function of prolonging life.

The knowledge of pills has been passed down by word of mouth for thousands of years, and there are not too many monographs in the world.

Since the Qing Dynasty, Western medicine has been gradually introduced into Huaxia, which has hindered the development of pills to a greater extent. In the pen of some quacks and novelists, the pill is very terrible and mysterious, but in fact, the clinical application of the pill from ancient times to the present day is extraordinary!

The pill originated from the alchemy of Taoism, and it is also the continuation and development of Taoist alchemy, alchemy and the pill are an inseparable whole, without Taoism, there can be no modern pill.

Dan is also known as Dan medicine, which is commonly found in traditional Chinese medicine and its preparations, but it is mostly used as surgical drugs and dermatological drugs. Today's elixir also benefits from ancient alchemy. It is also the continuation and development of alchemy. However, judging from the current trend of the use of pills, there are fewer and fewer varieties, and the scope of application is getting narrower and narrower.

Pill is a branch of traditional Chinese medicine medicine, which was created by the ancient warlocks of Huaxia Kingdom, in ancient times, the meaning of the pill is two, one is the elixir, and the other is the ordinary medicine.

The title of the pill profession practiced by the ancient warlocks is Wai Dan, which refers to the use of furnaces to smelt gold stones, prepare them into medicinal bait, and make immortal gold pills.

Regarding the medicinal pill, it has never been recorded in the classics of the Huaxia Kingdom. But Zhen Cheng clearly remembered that Miao Siren and the High Poison King had argued about this.

"Could it be that the medicine elixir refining method mastered by Yao Lao?" Zhen Cheng is a person who likes to use his brain, and although he usually speaks little, he likes to think in his heart. This kind of doubt, Zhen Cheng can't ask Yao Lao.

But judging from the perverted and weird kung fu of Yao Lao, Thousand Mountains Annihilation, and Thousand Feather Han, according to the current cultivation method, it is impossible to raise it to that level of perversion. Yao Lao's life is at the peak of the entire Kaikabo Peak, which is very illustrative of the status. Could it be that the people here are cultivating with the help of pills?

"Han Tie, the thirty-eighth generation disciple of Kaikabo Peak, has come to transport guano, please allow me to enter!" When Zhen Cheng was thinking wildly, a deep young voice spread through the entire medicine garden through that passage. The sound was not only there, but it shook the surrounding stone walls and buzzed, and there was a faint echo in the small space.
