After a long time, the light lights illuminated the bamboo slips in Cao Chong's hand. He looked at the bamboo slips carefully. Suddenly, a trace of memory in his mind was connected.

One nitrate, two sulfonates, three charcoal!

This was what Cao Chong saw on a post in a later generation. He found it interesting at the time, so he continued to read it. Now, seeing Zhang Wen's formula and the ratio of saltpeter charcoal sulfur, I can't help but think of that post.

As the saying goes: One nitrate, two sulfonium, and three charcoal, but actually making gunpowder is not that simple.

For example, saltpeter is not that simple to produce.

First, use a large iron pot for ordinary people to cook rice, add water, then put the earth and nitrate into the pot, boil the water, so that the nitrate dissolves in the water, and the debris in the earth and nitrate floats on the water surface, then use cowhide glue to make glue, pour it into the pot, stir and make the debris sinking at the bottom of the pot float up, and then use an iron spoon to make it out.

Repeat this repeatedly, and the aqueous solution of nitrate in the pot will be cleaned. Then lay a thick layer of dry wood ash on the ground, and then lay a piece of white fine cloth on it, and place the crystalline nitrate in the pot on a white cloth to absorb moisture. After repeating this for 2 to 3 times, it will be made of pure nitrate.

This is the purpose of making salt, and the balls of gunpowder-like things in Cao Chong's hand are made of earth-silt nitrate. The power is greatly reduced, but the key is that it may not sound!

Charcoal is not simply charcoal made from wood. Charcoal is made of willows grown in Huaibei. Later, because the source of willow trees gradually became scarce, they used hemp straw to place them in empty diesel barrels and burned them into charcoal by sealing them. The quality is better than willow charcoal.

Of course, this diesel barrel is a modern object, but Cao Chong can also make an iron barrel. As long as it meets the two conditions of sealing and calcining, it will meet the requirements.

The final process is mixing.

When mixing, they first dissolve the pure nitrate in water, then put the sulfur into the pot and stir, then put the charcoal of the hemp straw and suck it dry before preparing to roll it.

The black powder dried after crushing has powder, particles, and blocks, and the combustion is very uneven. They then use a sieve until uniform powder particles are made.

Of course, Cao Chong won’t recall the post for the time being, but the information he remembered alone is tens of thousands of times better than the recipe of the bamboo slips on Zhang Wen’s hand!

One is the scientific crystallization of five thousand years, and the other is the result of the alchemist's short-term thinking. The difference between the two is self-evident!

Cao Chong pinched the toy bullet-sized gunpowder particles in his hand and fell into silence, but this made Zhang Wen feel a little anxious.

Isn’t this Mr. Cao Qi going to break his promise, right?

"Young Master?" Zhang Wen called Cao Chong weakly, which awakened Cao Chong from deep thoughts!

Zhang Wen wrote a whole article about the contents of the bamboo slips, and he lost too much blood and did not faint. It was a good thing!

But Cao Chong was not going to let him go!

As the saying goes: Cut the grass without eradicating the roots, and it will grow again when the spring breeze blows!

If you kill him with one arm today, you will definitely be jealous of Zhang Wen, and he has the Golden Pill Immortal Medicine in his hand!

Well, although Cao Chong doesn’t believe that this is an immortal medicine, he can’t stand the superstition of this era. Eating a fairy pill can make you immortal. Who doesn’t want to!

If he touches some big shots, it will be very bad for him!

This risk cannot be taken!

Besides...

Cao Chong looked up at Huanye who served Zhang Wen like a slave, and knew that if he didn't let him see Zhang Wen's true face, he wouldn't have woken up from this so-called dream of immortality!

If he was obsessed with immortality and ate this heavy metal chronic poison, Cao Chong felt that his death was in the moment!

His death is naturally harmless, but Mrs. Huan is not easy to fool. What's more, although Huan Ye is incompetent, his loyalty is definitely much better than those of the Xin family's newly encamped families.

Cao Chong naturally had to do this to save his loyal subordinates!

"Zhang Wen, what's wrong with you?"

What's the matter?

Zhang Wen glared at his eyes, and he had an urge to curse in his heart. You, Cao Chong, are you the kind of person who is ruthless, oh no, you turn your back on others, right?

I said it well before, but now I have changed my mind?

So Zhang Wen had to remind Cao Chong again.

"Young Master, it's the previous agreement!"

"Oh! I promise, count naturally, Taoist Zhang doesn't need to worry!"

Before Zhang Wen could recover, Cao Chong said something again.

"But, I have a condition too!"

Zhang Wen was naturally angry, and his originally pale face turned red now!

You, Cao Chong, are a well-known person, you can't be so shameless!

"Please tell me!" The man had to bow his head under the eaves. Even if Zhang Wen felt uncomfortable, he had to swallow this breath.

"You ate this golden elixir on the spot!"

Did you eat the golden elixir on the spot?

Zhang Wen looked confused and thought he had heard it wrong!

"You want me to eat an immortal golden elixir on the spot?"

Guru...

As soon as this sentence was spoken, Cao Chong could easily see Huan Ye's saliva and his expression of not moving his eyes.

hehe!

The so-called golden elixir is just a poison. Besides, Zhang Wen lost too much blood. Now that he has taken this poison, it is very likely that he will go directly to see the Lord of Taishan Mansion and send you to death in advance. You don’t need to thank me!

"Yes, Taoist priest, you wrote the recipe for gunpowder for Cao Chong. I will give you an immortal golden elixir now, and also give you a golden elixir!"

"What the young master said is not false?"

Cao Chong's face showed a row of white teeth, a innocent face, and a young smile.

"Of course, I, Cao Chong, have a word that is as good as I can do!"

"Okay! The young master is indeed a hero!"

Zhang Wen was overjoyed, not knowing whether the young man in front of him was really stupid or fake. This is the immortal medicine!

Zhang Wen claimed that he had opened countless furnaces and practiced the immortal medicine of this type today. This is the first time that the efficacy of this immortal medicine may really achieve the so-called immortality.

You Cao Chong don’t want it!

Wow hahaha!

Zhang Wen laughed wildly in his heart, thinking about how to use this golden elixir to benefit himself, or even... avenge him!

The pain in Zhang Wen's body seemed to disappear in an instant. He picked up the box in his hand, opened it with pilgrimage etiquette, and finally kowtowed to the stone statue of Taishang Laojun, and then swallowed the golden elixir the size of a longan in one bite.

Once the golden elixir was swallowed, Cao Chong could see a touch of loneliness in Huanye's eyes and Gao Yi's trembling hands!

This is an immortal medicine!

Eat one and you will be immortal!

Cao Chong touched the short sword around his waist in his hand, and a sneer gradually appeared on the corner of his mouth. He quietly watched Zhang Wen's performance!

After swallowing a golden elixir, Zhang Wen had a smile on his face and a red face. When he looked at it, he felt much more energetic.

But Cao Chong knew that this was not so-called spiritual, but the psychological effect. The psychological effect was invincible and could scare a person to death!

Of course, you can also give your body some hints to make your condition better.

Tick ​​tick tick…

Time passes by moments!

Sudden!
Chapter completed!
