Chapter 395 Li Si Dengmen, the secret technique of making ice with saltpeter!
For people like Li Si, even if he is a minister of the Qin Dynasty, he only half-believes him.
In history, Li Si has already made a choice and exposed his true character. He is a person centered on self-interest. Therefore, in Ying Gao's view, as long as the same history continues, Li Si will still choose the same
road.
Such people should not only use it, but also guard against it.
"Young Master is a great talent, but after all, these hundreds of schools of thought have existed for hundreds of years, and their influence is very great. At this time, it is very difficult to weigh these hundreds of schools of thought!"
Li Si visited Ying Gao's residence. He actually didn't know why, but he didn't think highly of Ying Gao. He studied under Xunzi, so he naturally knew how deep the foundation of various schools of thought was.
However, Ying Gao was extremely ambitious, and such ambition was unacceptable to all schools of thought.
Li Si knew in his heart that Ying Gao's move would inevitably be met with a joint counterattack by hundreds of schools of thought, and even the Legalists would be involved. After all, this was the danger of the demise of the Taoism, and no one would ignore it.
........
"No matter how difficult it is, I will give it a try. Hundreds of schools of thought are powerful, but are they as powerful as our Qin Dynasty?" At this moment, Ying Gao took a deep look at Li Si, and his tone became more fierce: "Everyone in the world.
Below, we are all the king's land, and within the four seas, we are all the king's ministers. Who dares to resist? Maybe he wants to test whether my master's sword is sharp under the banner of the python swallowing the dragon?"
The murderous aura broke out, making Li Si's face suddenly become ugly. He felt great oppression from Ying Gao. This kind of young master who grew up in the war is definitely not comparable to the young master who was born in ease.
He had also met Young Master Fusu, but when compared with Ying Gao, there was a world of difference between the two in terms of momentum. At this moment, Li Si finally understood why there were all the young masters in Great Qin, but Ying Gao was just one
The third son, but the reason why the eldest son Fusu and the general Lu did not compete with Ying Gao.
It’s not that there won’t be a fight, it’s that the strength gap between the two sides is too big and there is no possibility of a fight.
As soon as his thoughts changed in his mind, Li Si made a decision, then bowed solemnly to Ying Gao, and said: "Whatever you plan to do, Master, if Li Si is needed, Li Si will go all out!"
"Um!"
Nodding, Ying Gao looked at Li Si and said, "Don't worry, Chang Shi. If necessary, Ying Gao will pay a visit. The Legalists of Great Qin should also understand what law is!"
"Does Chang Shi want to become a legalist giant in Qin?"
Finally, Ying Gao looked at Li Si and asked a question that made Li Si breathless. Obviously, in this era, becoming a giant is an honor and a recognition. (I only found out that the Mohist family is called giant, but for convenience
Let’s call them all giants!)
"think!"
Suddenly, the whites of Li Si's eyes quickly became bloodshot, and his breathing became heavy. For him to become a Legalist giant in the Qin Kingdom, this was recognition and an honor for him.
At this moment, Li Si's heart moved.
Li Si raised his head in vain, looked at Ying Gao, motionless, and said, "What do you plan to do, Master?"
"My master plans to make all the giants of the hundreds of families Qin ministers, so that the Qin court has the qualifications to dethrone the giants!" Ying Gao's words made Li Si's eyes flicker. He knew in his heart that what Ying Gao meant was him.
It will give all schools of thought a way out.
As long as you surrender to the Qin Dynasty, you can live.
He didn't understand why Ying Gao had such confidence, but what Ying Gao said made Li Si's heart beat.
In an instant, with happiness in his heart, Li Si raised his hand towards Ying Gaoyi and said: "Li Si will always be a minister of Qin. This fact can be learned from heaven and earth. You don't have to doubt it!"
"I believe in Changshi, just like my father believes in Changshi!"
.........
Li Si left.
I left very satisfied, and I also gained a lot from this meeting with Ying Gao.
Therefore, looking at Li Si's leaving figure, there was a smile on the corner of Ying Gao's mouth, which made Tie Ying very curious: "Young Master, Li Si does not have a close relationship with you, and the legalists of Qin are not weak, why should we make friends with you?"
give him?"
"Because he is the first person to come to see me. Success is reserved for those who are prepared, not just anyone. Li Si has an unlimited future!"
"As for the Qin Legalists, it's time to set up their own school!"
Fan Zeng chuckled lightly. He was very optimistic about Ying Gao's decision. He knew in his heart that Li Si was the sword in Ying Gao's hand. The Legalists of the Qin State, or the Legalists of the Central Plains, from now on, nine out of ten
Bow down to Ying Gao.
The young man in front of me would be really terrifying once he starts planning something.
Feeling the change in the weather, Ying Gao ordered Tie Ying, "Tie Ying, collect some saltpeter, the more the better!"
He remembered very clearly that the use of saltpeter was very early in ancient times. It was originally called "xiaoshi" and was used in medicine during the Warring States Period.
Saltpeter in nature is often formed by the decomposition of nitrogen-containing organic matter in the soil under the action of bacteria, oxidizing it into nitric acid and then combining it with potassium in the soil.
Therefore, whenever the air is crisp in autumn, it usually precipitates in the form of crusts or salt flowers, covering the ground and wall bases. This is the so-called ground frost. It is especially common in corners near pig pens, stables, and toilets.
Saltpeter farmers swept up the nitrate-containing soil, placed it in a bucket, and soaked it in water. After filtering, the filtrate was boiled or dried in the sun to obtain saltpeter crystals.
In addition, it is occasionally found on certain rock surfaces, caves, or salt marsh areas.
Therefore, it was not difficult to find saltpeter in this era.
"promise."
Nodding in agreement, Tie Ying turned around and left.
Seeing this scene, Ying Gao smiled slightly. This was the benefit of his confidant. As long as his orders were followed, Tie Ying would carry them out without asking any questions.
Ying Gao needs subordinates like Tie Ying. He knows that some things cannot be explained clearly, and it is very troublesome to explain them. He explains them one by one in a tone of voice, which is better than not explaining them at all.
Saltpeter was later often used to make black powder, fuses, glass, matches, fireworks, and was also used as potassium fertilizer, nitrogen fertilizer, etc. Saltpeter could be used to prepare malachite green glaze, and could also be used as a colorful and pastel pigment.
Even at the end of the Tang Dynasty, people mined saltpeter when producing gunpowder. They discovered that when saltpeter dissolves in water, it absorbs a large amount of heat and cools the water until it freezes. Since then, there has been a method of making ice in summer.
But this time, Ying Gao aimed at the art of making ice with saltpeter.
In the summer, when the weather is extremely cold, a large amount of ice is naturally needed. Maybe this will be a large sum of money. With this thought, Ying Gao became more concerned about this matter.
What's more, his mansion is stationed with Wan Shengjun and Iron Eagle warriors, so it is extremely safe. Generally speaking, no one can leak the secret technique of making ice with saltpeter.
