Pan Tianshi didn't care, after such a while, his brain seemed to be better, and he sighed and said: "Ge Tianshi is a pedantic celestial, how can there be a mistake!" Speaking of this, he sighed and said: "If you want to blame, you can only blame the teacher for being a little anxious?

Listening to his tone, everyone thought that there must be something wrong, and listened curiously.

I only heard Pan Tianshi say: "According to the records of Ge Tianshi, the teacher has been refining for a few days, but he still can't practice the elixir, so that the teacher is anxious, and then I remembered that some time ago, I studied the medical skills of Sun Simiao, the medicine king of the Tang Dynasty, for the teacher, and there are many records of alchemy in the "Taiqing Danjing Tips".

Everyone nodded, and no one was surprised, that Sun Simiao was smart since he was a child, he was determined to study medicine at the age of eighteen, and he treated his neighbors at the age of twenty. He has a profound study of classical medicine, attaches great importance to folk prescriptions, devotes himself to medical clinical research all his life, and is very proficient in internal, external, gynecology, pediatrics, facial features, acupuncture and moxibustion, and has 24 achievements that have created a precedent in the history of medicine in China, especially the discussion of medical ethics, advocating gynecology, pediatrics, acupuncture and moxibustion acupuncture points, etc. He has devoted himself to drug research all his life, and has gone to Emei Mountain, Zhongnan Mountain, Xiajiang Prefecture, and lived in seclusion in Taibai Mountain and other places, practicing medicine, collecting traditional Chinese medicine, and conducting clinical trials, and has devoted a lot of effort to pharmaceutical research. From the collection, processing and performance understanding of drugs, from the combination and compatibility of prescription drugs to clinical treatment, Sun Simiao referred to the medical literature of his predecessors, and combined with his decades of clinical experience, he wrote two medical masterpieces with important academic value in the history of China's medical development - "Qianjin Yao Fang" and "Qianjin Yifang". Among them, there are more than 5,000 prescriptions in the book, which not only contains medical theories such as diagnosis and syndrome, but also clinical departments such as internal and external, gynecology and pediatrics, and involves detoxification, first aid, health preservation, dietary therapy, acupuncture, massage, guidance, and vomiting, which can be said to be a good summary of the development of traditional Chinese medicine before the Tang Dynasty. The book contains nearly 3,000 prescriptions, covering materia medica, women, typhoid fever, children, nourishment, tonics, stroke, miscellaneous diseases, carbuncles, color veins, and acupuncture, etc., making a necessary and beneficial supplement to the "Qianjin Formula". Of the more than 800 drugs included in the book, more than 200 provide detailed information about the collection and preparation of drugs. In particular, it is worth mentioning that the book includes the articles of the "Treatise on Typhoid Fever" that have been scattered to the folk in the Jin and Tang dynasties, and constitutes nine or ten volumes alone, which has become the only research work of "Treatise on Typhoid Fever" in the Tang Dynasty, which has played a positive role in promoting the preservation and circulation of the articles of "Treatise on Typhoid Fever". Then, dig a pit in the ground and place the pot in the pit with the top of the pot flush with the ground, and fill the pot with soil around it. Then three soaphorns were lit with fire, and put them in the pot to make the sulfur and saltpeter burn fireworks. When the fireworks have just been extinguished, fry them with three catties of cooked charcoal. When the charcoal is burned by a third, the mixture is taken out while it has not cooled, which is called "Fuhuo", which is of great help to the later alchemists.

"Then master, old man, why did the explosion happen?" the eldest apprentice continued.

Pan Tianshi said: "The teacher is to grind sulfur and saltpeter into powder in equal amounts, put them into the Dan furnace, and according to the medical records of Sun Yaowang, add charcoal ...... to the Dan furnace?"

Except for the two disciples of Pan Tianshi, who knew a little about alchemy, the rest of the people did not understand the mystery, and one of the officials asked curiously: "It's just some charcoal, how can it explode?"

Pan Tianshi sighed and said: "My lord doesn't know, this recipe for the fire contains carbon, and the sulfur needs to be added to the saltpeter, and the saltpeter needs to be added to the sulfur, which can cause combustion, but somehow there is an explosion?"

Everyone was secretly surprised when they heard this, but Zhu Gaoxu frowned, as if he was pondering something, and he forgot to come to visit.

Pan Tianshi had just woken up, and had not yet seen Zhu Gaoxu, so he hurriedly asked how he came here, and when he heard that it was the King of Han who rescued him in danger, he was immediately shocked: "King Han, King Han, is he okay?"

"Haha, it's rare for the Heavenly Master to look like this and still cherish this king, so that the king is very happy, the Heavenly Master can rest assured, Hong Fu Qitian, the small alchemy room can't hurt this king?" A loud voice sounded behind everyone, and they quickly dodged the air, only to see Zhu Gaoxu walking to Pan Chun.

Pan Chun was startled when he saw Zhu Gaoxu, and said, "Lord, poor road, poor road, poor road, poor road, ......poor road,

Zhu Gaoxu looked at him, laughed and said: "It's just a few houses, it's a big deal to rebuild it, but the Heavenly Master is the right-hand man of this king, and there can't be anything?

"Thank me?" Pan Tianshi was a little confused, and looked at Zhu Gaoxu with a puzzled expression.

Zhu Gaoxu looked at him, and laughed again: "Listening to the words of the Heavenly Master just now, this king thought about it carefully, if this king thinks well, the Heavenly Master has put three drugs of sulfur, nitrate, and carbon in this Dan furnace, if these three drugs are put into the Dan furnace alone, it will be fine, but the three drugs put together, can constitute an extremely flammable medicine?"

"An extremely flammable medicine?" Pan Tianshi glared at him, "Then what is this?"

"Well, I don't know about this king?" Zhu Gaoxu has read a lot of books recently, although he doesn't dare to call himself a literati, it can be seen that he has a little more knowledge, but let him explain this, he really can't say it for a while, and his face is a little ugly.

"Is it gunpowder?" said a sharp voice.

Everyone followed the prestige, only to see an old man about fifty years old walking in outside the door, with a wide forehead, a round face, a smooth chin, and light eyebrows and thin eyes.

Zhu Gaochu and everyone got out of the way, and the old man walked to the bed, first bowed to Zhu Gaoxu, and then said: "The Dan family often uses the method of cauterizing sulfur, arsenic and other poisonous gold and stone medicines before using them, and "volt" means to subdue. Losing or reducing toxicity is called "fire". The fire contains sulfur and nitrate, and the Heavenly Master will have a violent reaction when he adds carbon to mix and ignite, and it is inevitable that an explosion will occur?"

"Gunpowder!" Pan Tianshi said with palpitations as he remembered the scene just now.

When Zhu Gaoxu heard that it was gunpowder, he immediately said with a happy face: "Gonggong Huang, is it really gunpowder?"

This old man's surname is Huang Dan's name, originally the inner servant of the Yan Wangfu, when he was in the Yan Wangfu, he was not on good terms with Zhu Gaochi, the son of the Yan Wang, and the second son Zhu Gaochu and the youngest son Zhu Gaosui were very close, especially Zhu Gaosui, Huang Yan was his sworn friend, in the early years of Jianwen, Yan Wang Zhu Di launched the "Battle of Jingyan", and attacked Emperor Jianwen to the south in order to seize the throne. At the time of Zhu Di's expedition, the history books recorded that "Huang Yan of the Eun Temple loved Gao Sui as a child, and the plan to win the heir for the matchmaker would be his own benefit, so that his party contacts were rare and the emperor (Zhu Gaochi) was short, and the emperor was also said to be the emperor for the imperial court to stick to Beiping to reject his father." Huang Yan kept saying bad things about his son Zhu Gaochi, and at this time, Emperor Jianwen adopted Fang Xiaoru's opinion and decided to use a counter-plot to separate Zhu Di's father and son, and sent a letter to Zhu Gaochi, promising that if he betrayed his father, he would be named King Yan. After Huang Yan got the news, he preemptively told Zhu Di first, but fortunately, Zhu Gaochi had already sent someone to send Fang Xiaoru's letter to Zhu Di intact, so Huang Yan's conspiracy did not succeed, but the relationship with Zhu Gaochi was getting worse and worse.

After the efforts of Xie Jin, Yang Shiqi, Yang Rong, Hu Ying, Yang Pu and others, in the second year of Yongle, the son Zhu Gaochi was canonized as the crown prince, and Zhu Gaochu was named the king of Han, and Zhu Gaosui was named the king of Zhao. King Han and King Zhao both have the heart to seize the heir, King Zhu Gaosui Yunwen Yunwu, smart and extraordinary, although ambitious, but deeply hidden, so he is deeply loved by the ancestors. Huang Yan also attached himself to King Zhao, ready to serve his coveting of the throne. Huang Yan was a celebrant eunuch during the Yongle period, with a high position, and he really sought a lot of benefits for Zhu Gaosui, the king of Zhao.
