Prosperous Tang Soul

Chapter 304
Among the civil servants, Pei Ji's martial arts is the best, and among the military officials, Qin Qiong's culture is the highest. Although Zhang Yi's culture is not high, his handwriting is something that even Niu Jinda can't catch up with.

Although it can't be said that the silver hook is painted with iron, it is better than neatness. With a few strokes, the formula of the two gunpowder was completely written down by Zhang Yi.

"General, this is the formula for gunpowder bombs, please have a look!" Standing up, Zhang Yi handed two pieces of kraft paper to Niu Jinda with both hands, and said: "Concocting gunpowder bombs is very simple, it is nothing more than the fuse, the body and the seal. There are no technical requirements for this part. However, the formula of the gunpowder is the most important thing, and it must not be disclosed to the outside world!"

"Snapped!"

I got a slap on the forehead.

"I don't know how serious it is at this age?" Niu Jinda was addicted to beating people, glared at Zhang Yi angrily, and then sat down on the low couch, comparing the text on the two formulas one by one, After confirming that it was correct, he took out one of them, put it in an envelope together with the previous letter, then skillfully sealed it with wax, and ordered outside the account.

"Come on!" Niu Jinda shouted.

Immediately, a personal guard quickly opened the tent and entered.

"General!" The guard cupped his fists and saluted.

"The general ordered you to bring a hundred elites, and send this letter to Chang'an as soon as eight hundred miles away, and hand it over to His Majesty!" Niu Jinda ordered: "Don't let it fall into the hands of the second person. Trust is in the person. You must destroy the letter before you leave!"

"Yes!" The soldiers shouted, and immediately understood the importance of the letter, and once again clasped their fists in a hurry to remove the tent.

Niu Jinda took the remaining formula, weighed it for a while, and finally made it into a paper ball and stuffed it into his mouth. After chewing hard with his teeth a few times, he swallowed it in one bite.

"Boy, are you the one who gave the big firecracker the name of the gunpowder bomb?" Niu Jinda stood up again and looked at Zhang Yi.

"Ah, yes!" Zhang Yi quickly said with a smile: "The general is indeed wise, it is the gunpowder bomb!"

"What a wise man! Don't make fools of this old man!" Niu Jinda waved his hand, and said seriously: "Gunpowder bullets are so powerful that they are unique in this world, and their power is still higher than that of the eight-ox crossbow. According to this old man, it is the best for defending the city." No more! Boy, tell me honestly, this secret method comes from "Taiping Essentials"?"

Zhang Yi was shocked when he brought up the important technique of peace again!
Then there was a slight chill in my heart.

Niu Jinda's words can be said to be on point, but on the other hand, it is also a reminder to Zhang Yi for the last time.

The power of gunpowder bullets can be said to be an insurmountable gap in the era of cold weapons. It would not be an exaggeration to say that it is a magic trick of the fairy family.

Such an artifact, as long as it is used properly, is simply an invincible existence, so it is logical that it is mistaken for it to come from the essential technique of peace.

Regardless of whether it is a family or a king, or even a treasure that every ambitious person wants to obtain, once people know that it is in Zhang Yi's hands, the consequences will be disastrous.

"Of course not!" Zhang Yi hurriedly explained: "Gunpowder, which is the most critical material for flame bombs, is actually not the first thing I discovered! If you want to go back to history, it actually appeared as early as the pre-Qin period, but The gunpowder at that time was different from the current one, and it was discovered by accident, and no specific formula was sorted out.”

"Already appeared in the pre-Qin period?" Niu Jinda couldn't help being taken aback.

Zhang Yi's answer made him a little bit at a loss. In his memory, there had never been such a domineering weapon in the pre-Qin period!

If it appeared, how could it be lost?

"That's right!" Zhang Yi continued: "In the pre-Qin period, there were a hundred schools of thought contending, and Daoism is actually one of the hundred schools. I don't know if General Niu can agree with it!"

"Although I come from a slightly cold background, I have heard that the Taoist school was one of the hundreds of schools in the past!" Niu Jinda nodded, agreeing with Zhang Yi's statement, and asked immediately: "However, what is the Taoist school?" What is the connection between gunpowder and Taoism?"

"Of course there is a connection!" Zhang Yi excused: "Taoism emphasizes the nature of all laws and the unity of man and nature. Since ancient times, there has been a theory of outer alchemy and inner alchemy! This inner alchemy focuses on the cultivation of the spirit and the human body. There are many stories about ascension to immortality, but they have always been legends. Of course, apart from the classics, no one I know can really ascend to the ascension. That's all."

"Well, that's true! Leisurely asking is actually bullshit, and the old man doesn't believe it!" Niu Jinda nodded, motioning Zhang Yi to continue.

"And the so-called outer alchemy is the alchemy we are familiar with!" Zhang Yi said: "For example, the five stone powder that is popular in Chang'an now, and the Dragon and Tiger Pill refined by Sun Daochang are actually in the category of alchemy. It's just that the former is for the promotion of immortality. Daoist Sun is for saving people, but the essence is the same. I was lucky enough to see such a record in a Taoist miscellaneous book in the past. It is about the alchemy of lead and mercury. During the long refining process, he accidentally added a medicinal material, which caused an explosion. Although he survived in the end, he was dying. In order not to lose the formula, he recorded the compatibility of the pill formula and the last added medicinal material. Come down!"

Niu Jinda regained his energy immediately, and hurriedly asked, "Is there anything else?"

"General Niu, do you think the kid dares to tell lies in front of you?" Zhang Yi made an appearance that you are an uncle and I dare not lie to you: "So, I conducted research based on that house, and finally recovered. It was something that exploded at that time, and it was named gunpowder. Not only that, but in the process of recovery, I also found that if the medicine was added to water, it could completely absorb the heat in a short time, so that the condensed water would freeze, which is also true. It is the origin of the summer ice-making method!"

Niu Jinda's heart was full of turmoil.

If Zhang Yi's method didn't come from the essential techniques of Taiping, then Zhang Yi is simply a monster!
To be able to restore gunpowder with a few words in miscellaneous books, and to find other magical uses from it, this is undoubtedly the name of a ghost!

He has eaten ice cubes before, and a piece of ice cube is very beneficial in the scorching summer.

And the power of gunpowder bullets is the ultimate weapon for defense and killing the enemy!

A person who can come up with so many things is simply a living treasure!

but
Niu Jinda thought again, but what if Zhang Yi lied?If these methods come from the essential techniques of peace.
For a while, the entire camp fell into silence again!
　 It's been a long time since there was an explosion, how about a chapter 5 explosion today?
