Opening mountains and cracking stones?

Yuan Luqian looked at Pei Min inexplicably.

Pei Min thought of black gunpowder. As one of China's four great inventions, the emergence of black gunpowder changed the history of human wars, and changed from cold weapons to the development of hot weapons.

Black gunpowder plays an absolutely important role in promoting the development of world history.

The role of black gunpowder is actually not limited to the battlefield, but as a battlefield killer.

Killing is only part of the function of black gunpowder, and it is also the value of black gunpowder for benefiting the world.

It is actually not difficult to open mountains and build ridges. It is difficult to encounter various difficult problems during the process of opening mountains and building roads. For example, mountain rocks as hard as iron and huge rocks that cannot be lifted by manpower.

In ancient times, when there were no digging trucks and weightlifters, when encountering such mountain rocks and huge rocks, people needed to use manpower to chisel the mountain rocks and huge rocks bit by bit, break them bit by bit, and then transport them down the mountain little by bit.

Most of the time spent on opening mountains and repairing ridges is spent on digging mountain rocks. If there is black gunpowder on top of the mountain rocks, forced explosion of mountain rocks and huge rocks will shorten the construction period by more than half.

As long as there is black gunpowder, all problems can be solved!

Seeing Yuan Luqian's face full of ignorance, Pei Min explained with a smile: "I once read a recipe in an ancient book, saying that as long as the sulfur, carbon, and nitrate are combined according to a certain proportion, they will be made into black gunpowder. Through combustion, it will produce huge power and have the effect of breaking mountains and cracking stones. If we can make black gunpowder and use black gunpowder as the help of the arm to open mountains and repair mountains, even if Longshan is strong and Wushaoling is steep, it will not be difficult for us. As long as the court supports it, it will be enough for a year."

"Black gunpowder?" Yuan Luqian pondered for a while and said, "I have only heard of gunpowder. I have never heard of black gunpowder. Can the book record the detailed formula?"

Pei Min slapped the table in anger, regretting it. As a liberal arts student, he didn't know much about black gunpowder. He just knew what materials, but the proportions, and I really couldn't remember them very clearly. I vaguely remembered that I had memorized an equation of one, two, and three. I couldn't remember what specific one, so I could only shake my head in annoyedly and said, "I just couldn't remember it for a while. The ancient book has long disappeared. However, it doesn't matter. Knowing the materials, there is no reason why I can't make it. I have never lacked Taoist priests who cultivate immortals and refine alchemy in the Tang Dynasty..."

The Tang Dynasty established a country with Taoism. In order to improve the status of the Li royal family in the hearts of the people, the royal family also shamelessly recognized Laozi Li Er as their ancestor and promoted Taoism.

Taoism takes Huang and old Taoist thoughts as its theoretical basis, inherits the magic of immortals since the Warring States Period, and takes "Tao" as its highest belief, believing that "Tao" is the origin of all things.

In particular, Maoshan Taoist Ge Hong combined Taoist magic and Confucianism and the Confucianism and the famous teachings to build a system of immortals, forming the upper-class gentry alchemy Taoism.

Taoism in Danding mainly focuses on alchemy, with sulfur, realgar, mercury, arsenic, and saltpeter as raw materials to practice elixirs for immortality.

Because these materials contain highly toxic, Taoists have studied various methods of removing poison, the most famous of which is the fire method and alchemy, which uses fiery fire to subdue highly toxic, and thus practices the metal and stone medicine that can survive forever or cure all diseases.

Black gunpowder was discovered unexpectedly in this situation, full of accidentality.

Pei Min already has a recipe in his hand. As long as this accident becomes inevitable, black gunpowder will definitely be born early. While it is used to benefit the people of the world, it can also be used in future wars, with the best of both worlds.

"In this way, Brother Lu Qian, go find some Taoist priests who are good at alchemy, and collect some sulfur, carbon, and salt. If we can really develop black gunpowder, we will open Longshan, build Wushaoling, and complete an unprecedented feat!" Pei Min's eyes shone with a few excitement.

The same is true for Yuan Luqian. If everything is achieved, open Longshan, build Wushaoling, and open up the most convenient Western Regions business roads.

Then they will seek thousands of years of convenience for the development of Longyou and become a world of honor, just like Li Bing who built Dujiangyan and Zheng Guo who opened Zheng Guo Canal.

"I'll do it now!" Yuan Luqian went there in a hurry.

Pei Min was thinking about gunpowder and was unwilling to handle official duties. He thought that Chang'an was the center of the world and had many Taoist temples. Ye Fashan, the religious leader of Taoism, was still his neighbor. After a while, he personally wrote a letter and asked someone to deliver it to Chang'an and handed it to Ye Fashan.

************

Chang'an Yuzhen Temple.

As a Taoist priest, Ye Fashan was highly valued by Li Longji. He not only gave him the status of Yin Qing Guanglu Dafu, the Minister of Rites and the Heavenly Master of the State of Guarding the Country, but also named him Duke Yue and became the Duke of the State of the State of the State of the State, which shows his favor.

This is the way of alchemy to his disciples.

Taoism takes nature as its basis and nature as its respect, advocates self-discipline, and serves things in harmony. It emphasizes the art of immortality and is well-versed in health preservation.

This alchemy technique is a must-learn science in Taoism.

Ye Fashan looked at the reserved student under his school and felt a headache. He glanced at the young girl who was excited to hear it, and felt quite helpless in his heart.

The young girl is Princess Yuzhen Li Chiying. This princess who is already graceful and elegant, listening to the class with relish.

However, her innate princess aura made her disciples and disciples around her dare not breathe and shrank, and she would occasionally take a look from afar from time to time, so how could she listen carefully?

"Go down, go down!" Ye Fashan waved helplessly.

Most of the disciples and grandchildren breathed a sigh of relief, bowed silently to Li Chiying, and hurriedly left.

Li Chiying laughed and said, "Why doesn't the Heavenly Master teach? Chiying is listening with relish!"

Ye Fashan held his forehead with his hands and said, "This alchemy technique is truly a niche knowledge. The princess is talented and has a clear understanding of everything. There is no need to learn this alchemy technique."

Li Chiying was very careful and said: "Taoism focuses on cultivating one's own nature, regulating yin and yang, harmonizing qi and blood, and protecting spirit as the principle, and using the method of diagnosing the spirit, guiding breathing and inhaling, adjusting the four seasons, Feng Shui environment, Taoist calligraphy and painting, tea, food and medicine to harmonize yin and yang, unblocking qi and blood, nourishing essence, exercise muscles and bones, and nourishing the internal organs. Alchemy is regarded as one of the health preservation, what is a small technique?"

Ye Fashan had nothing to say. Over the years, he knew his special disciple so well.

She was not very interested in Taoist theory, but she was extremely talented. She listened to him from time to time over the years and knew the basic theories of Taoism. It was not easy to hide them from her. She could only say: "The art of alchemy is too dangerous. How can the princess's daughter be in danger?"

Li Chiying said enthusiastically: "Zhi Ying has no great interest in the art of refining alchemy and immortality. He dared not disbelief, but he dared not believe it deeply. The reason for each of them is not said, and the Heavenly Master knows it. What I am interested in is the fire in Yuzhen Temple back then. The fire in Yuzhen Temple in the past has been clear. It is actually the thief who intends to assassinate the Duke and involves the Duke in the Palace. But according to the assassin's instructions, he set fire only to lead the Duke out of the Duke, rather than burning the entire Yuzhen Temple in the Palace. It is actually the fire spreading to the Danfang, and accidentally ignited the sulfur, cinnabar and other things in the Danfang. For some reason, the Danfang collapsed and was destroyed, and even the alchemy cauldrons cracked four times, thus making the fire uncontrollable. If the Duke was not in the proper command and the Emperor's rescue was timely, the entire Yuzhen Temple in the Palace would be turned into ashes."

Ye Fashan looked embarrassed. He did know this, but people in the world attributed the mistake to the assassin. He was happy that he did not say it out loud, but he didn't think that Li Chiying had already known it clearly.

Li Chiying continued: "In recent years, my palace still remembers the fire freshly and often wakes up from nightmares. I can't help but read ancient books to understand clearly and calm my heart. I accidentally discovered that this matter is not uncommon in books. There is an essay that records: In the early years of the Sui Dynasty, Du Chunzi's people visited an old alchemy man. He woke up in the middle of the night and saw that there was "purple smoke on the house" in the alchemy furnace, and the whole house burned. The alchemy book "The Essay on the True Yuan Wonderful Dao" also talks about the incident of using sulfur, saltpeter, realgar and honey to refine alchemy together. Jiying was curious and secretly took small sulfur, saltpeter, realgar and other things. Sure enough, the flames were raised, but I don't know why?"

Ye Fashan stammered and couldn't tell the reason. They already knew that the alchemy objects were easily fired and even bursting sounds, but the reason was not something they could know. He paused and said, "The princess really asked me to tell me why, but I couldn't tell the reason. I only knew that after research, the medicine king Sun Simiao found that elixirs such as sulfur, cinnabar, and mercury were toxic and harmful to people and could save people. In order to reduce the toxicity of gold and stone drugs, he summarized the "Fuhuo"

Method, intentionally make the drug easily catches fire and burns itself to remove its toxicity. It is recorded in Qianjin Fang that it uses 2 taels of sulfur and 2 taels of saltpeter each, grinds it into powder and puts it into a pot; Chiang uses three soap beans to cause fire, saltpeter and sulfur to burn, after the fire is extinguished, stir-fry with raw and cooked charcoal until the charcoal is eliminated. As for why it burns, I have discussed this with Doctor Sun in the past. Doctor Sun could not say it, but said that this method should be cautious, and it is not used well, and may even harm human life."

Li Chiying looked at Ye Fashan in shock.

Ye Fashan said solemnly: "So princess, please listen to my advice. You are a golden branch and a jade leaf. It is better not to touch such dangerous things."

Seeing that Ye Fashan was serious, Li Chiying could only respond: "I know! I won't bother Master Tian!"

Ye Fashan looked at Li Chiying's departure and felt relieved. After thinking about it, he sent an order to remove all the alchemy objects from Yu Zhenguan before he felt relieved.

That night, Ye Fashan received a letter from Pei Min.

Ye Fashan attached great importance to Pei Min. The two had no contacts except for their previous encounters. However, it did not hinder Pei Min's deep friendship with a close friend in the heart of this leader of the Taoist sect in the world.

The reason is nothing else. Ye Fa is good at emphasizing Taoism over Buddhism, and he is extremely repulsive of Buddhism and has repeatedly defamed Buddhism. Pei Min's idea of ​​destroying Buddhism has caused severe damage to Buddhism all over the world, which has greatly attracted his spleen and stomach.
