Chapter 1140 Directional Choice
Song Zhong frowned and didn't say much to Yuan Shu.

He really wanted to go one step further and go to Taixue to make a sacrificial wine, but it was useless to talk to Yuan Shu about these words, he would only be ridiculed by him.

"You just arrived in Wancheng?"

"Well, it's been less than half an hour since I entered the city."

"Then do you know that many people are forced to go west today?" Song Zhong snorted. "Including your son, Brother Yuan Tan."

Yuan Shu was taken aback. "Leave today?"

"I've already left, I just went to see Zong Shilin off..."

Before the words finished, Yuan Shu turned around and rushed out.Song Zhong opened his mouth, watched Yuan Shu's back disappear outside the door, and shook his head after a while.

"This brat, who is almost fifty years old, is still so useless."

Yuan Shu left the county school, jumped on his horse, rode fast with his entourage, and left the west gate to catch up with Yuan Tan and Yuan Mai.

Seeing Yuan Shu chasing after him, Yuan Tan was both surprised and happy, and couldn't help crying.

This time he was exiled to the Western Regions, he never thought that there would be a possibility of returning.Before parting, the person he most wanted to see was Yuan Shu.Mrs. Yuan said that she had already delivered a letter to Yuan Shu, but she was not sure whether Yuan Shu would come in time.

He was already on the way, but Yuan Shu arrived, and his wish was fulfilled.

The uncle and nephew held hands and looked at each other with tears in their eyes. For a moment, they didn't know what to say.

After a long time, Yuan Tan wiped away tears. "I'm really ashamed to implicate Ah Heng."

"Hey, it's all a family." Yuan Shu waved his hand, signaling Yuan Tan to stop talking.

He was also at a loss about this matter, not knowing what was going on.He wrote a letter to Yuan Heng asking what happened, but he has not received a reply yet.

But the benefits are obvious. This time when he came to Wancheng, many people on the way treated him well, at least much more politely than when he came to Nanyang last time.

At least according to public opinion, Yuan Heng should have played some role, but he didn't know it.

"Can you hold it up?" Yuan Shu patted Yuan Tan's shoulder and looked him up and down.

"It's okay." Yuan Tan said with a wry smile, "These four years of hard work have not been in vain."

Yuan Shu glanced at him, wanted to laugh but didn't.Of course he knew what Yuan Tan's hard work was for these four years, but he didn't expect that it would be used for it in the end.From here all the way to the Western Regions, it is really impossible without a good body.

He turned his head to look at Yuan Mai, and smacked his lips. "Who is responsible for the escort? Do I know him?"

"Uncle, please rest assured." Yuan Tan said in a low voice, "The emperor arranged for Gao Rou to be escorted along the way, and there is no intention of embarrassing him."

Yuan Shu raised his eyebrows and immediately understood.He patted Yuan Tan on the shoulder. "When you go to the Western Regions, don't let that kid from the Xun family look down upon you. You and Xianyi go east and west to see who can go further. In the future, I will write your names on the genealogy."

"Here." Yuan Tan felt much better, and bid farewell to Yuan Shu.

Yuan Shu stood on the side of the road, watching Yuan Tan and the others gradually move away, thoughtful.

After a long time, he sighed. "The situation is bigger than the people, so choosing the right direction is very important."

-

Back in the city, Yuan Shu went directly to the imperial camp.

Liu Xie is discussing the experimental plan of gunpowder with Wei Ao, Yu Ji and others in the lecture hall.

The composition of gunpowder is not complicated, and the ratio is also clear, but he did not tell them directly, but let them experiment slowly, sum up the rules from it, and find out the optimal ratio and processing technology.

For him, scientific thinking and methods are far more important than results.

His greatest contribution was just changing the direction of research, changing how to avoid explosions into how to explode more violently, and turning the elixir of longevity into a sharp weapon for killing people.

Of course, explosives are not just weapons for killing people, they can also be used in mining.

This is already in his plan.

Industrialization is a whole system, not just a few technologies.

Hearing that Yuan Shu was visiting, Liu Xie was a little surprised.

He didn't call Yuan Shu to Nanyang, and Yuan Shu was not a county official, so he didn't have a mission to count, so why did he come to Nanyang?
Are you here to intercede for Yuan Tan, or to cry out for Yuan Heng?

Liu Xie thought for a while, but didn't summon Yuan Shu immediately and told him to wait outside.

Wei Ao finished his recent research progress, and then asked a question: Why can gunpowder burn in a sealed container?
After many experiments, they have come to a conclusion that gunpowder has an extremely strong burning ability, which is essentially the same as burning other things, only more violently.

But what they can't understand, why can't other things burn in a sealed container, but gunpowder can?

What exactly is in here?
Hearing Wei Ao's question, Liu Xie almost laughed out loud, the joy in his heart was not inferior to hearing the news of gunpowder for the first time.

As expected of a genius who could write "Zhou Yi Can Tong Qi", he discovered the root of the problem so quickly.

The dawn of the scientific revolution will soon appear with the bang of dynamite.

At the beginning of the third decade of the [-]st century there is a new theory that the so-called scientific revolution can be subdivided into revolutions in two disciplines.One is physics, represented by the mechanics of Galileo and Newton.One is chemistry, represented by Lavoisier's combustion theory.

The emergence of these two disciplines is inseparable from gunpowder.

The emergence of mechanics was originally to solve the problem of artillery shooting accuracy.The emergence of combustion theory is to solve the performance bottleneck of gunpowder itself.

These are the most realistic questions.

It is practical needs that gave birth to modern science, not some apples that fell from the sky.

Now, he has created this need, and he has completed the birth of science.

Wei Ao in front of him is the most typical example.Without him, Wei Ao would only be a Taoist alchemist, not a real chemist.

Of course, Galileo and Newton were also alchemists in essence, and then scientists.

"What was the result of your discussion?"

"I think that if anything wants to burn, it needs not only flammable wood and fire to ignite, but also breath. This breath may be similar to the breath of breath, but the opposite of the breath of breath... "

Wei Ao talked eloquently, which was completely different from the reluctance and helplessness when discussing the power of gunpowder.

He explained his findings in detail.

After experimenting, he found that the residual gas after the explosion of gunpowder is similar to the gas spit out of the mouth, and the gas generated after the burning of ordinary wood, which can make the clear lime water turbid.

Therefore, it can be deduced that the three substances that make up gunpowder must contain the vitality that can make charcoal burn.

Considering smoldering with charcoal, even if there is gas, it will be burned away. He guessed that this gas is in sulfur or saltpeter.He intends to test these two things separately to see what results he can get.

Liu Xie was very emotional.

This is the difference between a scholar and a craftsman.

The craftsman only asks the result, not the reason.They pay attention to the accumulation of experience, but do not explore the principles behind it.Scholars, on the other hand, want to understand the principles behind it rather than the specific results, which is the so-called Tao.

As an alchemist with both practical experience and theoretical pursuit, Wei Ao was born to be an excellent scientist, but his pursuit was in the wrong direction.

There will be no results in refining alchemy, but refining gunpowder can.
