Great Song

The Baojia method was coming in a menacing manner, and Wang Anshi clearly relied on the support of the emperor, wanting to go his own way.The gentlemen in the court only wish they could put all their heart and soul into it, so that the emperor would wake up.Unexpectedly, the situation suddenly changed, and Baojiafa changed a lot and changed its appearance.

No more recruiting troops for military training, and cancellation of training sessions and teaching readings, but joint households to ensure stability in the village.If a bandit wanted by the government is captured by the insurance household, rewards will be given and taxes will be reduced or exempted.Of course, if the Baozhong secretly hides the bad guys, once they find out, they will even sit down.Although this method still has some shadows of being in a hurry, it is much safer than Shang Yang's "evil method".In fact, what most officials objected to was not the settlement of bonds, but the drill of the militia.Once those mud legs have learned martial arts, guns and sticks, what should they do if they refuse to obey discipline?As for punishing evil and rewarding good, it can also reduce robbery in the village and allow the rich to live in peace.

On the contrary, the saying that the veterans were dismissed, selected and arranged in the countryside, and assisted the county lieutenant in maintaining order, made some people slightly worried.But there are still not many objections.After all, everyone knows that there are redundant soldiers, and the inability of soldiers to fight makes many people of insight worry.It wouldn't be a bad thing if some soldiers who would only eat their pay and avoid laziness could be abolished.As for how to arrange it in the village, that's another matter. It's not impossible to handle it carefully.

For a while, the reformed Baojia law received a lot of praise.There are also well-informed people who know Zhang Zai's role in this matter.This upstart of the Privy Council seems to be appreciated by the emperor.

It's just that I was happy for a few days, and heard about the general's art of war that the Privy Council is going to implement.It is necessary to change the four levels of Xiang, Jun, battalion, and capital of the imperial army into three levels of general, department, and team, eliminate the old and the weak, and merge the barracks.Soldiers no longer have tattoos on their faces, and they must be assigned to specific generals for drills, changing the bad habit of "soldiers don't know generals, generals don't know soldiers".

This caused an uproar again.Many people have brought out the precepts of their ancestors, and they have written a long list of the disasters of the feudal towns in the late Tang Dynasty and the disaster of the rebellion of the Five Dynasties.Some people earnestly persuaded the emperor that Song and Liao had already formed an alliance, so they should not rashly train troops.In case the Liao Kingdom misunderstood, wouldn't there be another war?Of course, the promoters of this law have also attracted various criticisms.Some people yelled at Zhang Zai, calling him a gentleman, how can he have the demeanor of a great Confucian?He is just a villain who seeks fame and fortune and caters to the emperor.

For these, Zhang Zai didn't care at all, and only devoted himself to revising the new law.This art of war will be tried out on Jingyuan Road this year.Cai Ting, the envoy of Jingyuan Economic Strategy, had already started to reform the military. Now that he has the support of the imperial court, he is even more powerful.As long as the new law achieves results in Shaanxi, it will be logical for Cai Ting to join the cabinet as prime minister in the future.

What is rare is that his other recommender, Lu Gong, also agrees with the general's art of war.Now Zhang Zai has no worries and can innovate freely.Even if Prime Minister Fu Bi disagrees with this matter, it is nothing to Zhang Zai.The prime minister can go or stay, but the war waits for no one.How can the fame that I have cultivated for more than ten years compare with the lives of the soldiers of Bianjun?

However, compared to these innocuous criticisms, Zhang Zai is more interested in another statement that has been circulating recently.If the atmosphere in the ball can be evacuated, what should be left?

"Brother Zhen, brother Zhen! Have you tried the suction tube? This thing really relieves fatigue! Look at this bruise on my shoulder, it was just sucked out..."

It was said to be a literary meeting, but Mi Fu rolled up his sleeves as soon as he came up, showing Zhen Qiong the round red marks on his shoulders.

Zhen Qiong's face turned dark: "What's so interesting about this? I'm not sick, so I won't go for cupping!"

Isn't this sick?She ran to cupping for nothing, and her whole body was covered in bumps and reds and purples, which really puzzled Zhen Qiong.

But Mi Fu shook his head: "This is to get rid of the disease in the body. Some people pull out the red seal, and some people pull out the black seal, but the poison gas in the body is different. These are hidden diseases. Who knows when it will happen? Besides, there are Treat illnesses, and strengthen your body even without illnesses. Even brother Zizhan is full of praise for this method!"

Hearing his words, Su Shi on the side really nodded in agreement: "The bamboo tube has been soaked in boiling water, and when it touches the body, it has a huge suction force, which must be due to the different air pressure. Isn't it possible to use the power of heaven and earth to suck out the sickness in the body like this?" Physical fitness?"

Su Shi has dabbled in all kinds of health-cultivating methods, and has also learned some Taoist breathing and alchemy techniques. He has a special liking for this new healing method derived from atmospheric pressure.

Zhen Qiong's head exploded when he heard this: "How can it be used to strengthen the body by curing diseases? Besides, the bamboo tubes for cupping have to be soaked in boiling water. Are you not afraid of blisters and skin ulcers?"

"If the workmanship is good, of course not." Su Shi replied quite calmly, and said with some complacency, "Besides, the heat can also cause the air pressure to vary. Isn't this worth investigating?"

If you want to study it, you should study it carefully. What's the matter with cupping?Zhen Qiong laughed angrily: "So, if you heat the glass jar with fire and put it on the meat, can't you observe more carefully?"

They also have cupping, but who would use this method to study atmospheric pressure?Do these people understand what Gewu is? !

Unexpectedly, his angry words made the eyes of both of them light up at the same time.

Su Shi clapped his hands and praised: "This method is wonderful, Ling Xiaozi is really quick-witted!"

And Mi Fu happily nodded vigorously: "Yes! I changed to a glass jar, and it is much cleaner than a bamboo tube. Then burn it with fire, and it will definitely be gone!"

He was also worried about the uncleanness of the bamboo tubes. Every time he went for cupping, the store had to change the tubes, and he had to boil them carefully before using them.If I use my own glass jars in the future, wouldn’t it be enough to wash them well if they get dirty?

Zhen Qiong: "..."

All right, pull it out if you like!

Shen Kuo smiled and said, "Physician Qian also said that some people in the palace began to study the method of sucking cylinders. Maybe they can really form their own school in the future, like needle stones. But the principle of suctioning cylinders is not that the air pressure will decrease when it is heated. But once the air is heated, it will expand, and it will suddenly cool down and shrink when it is buckled on the body, which creates a pressure difference and can suck up the flesh."

Listen, this is what people say!Zhen Qiong suddenly felt a confidant, and Shen Kuo was the most reliable!

However, Su Shi was aroused by this topic: "I used to condense water into ice in winter. The ice cube would bulge out of the bowl, which was obviously bigger than before. How can I replace it with air, and it will shrink when it gets cold?"

"When water turns into ice, it changes its shape. The heat expands and contracts, and it must be the same thing. It's like the floor at home. If the material is not good, it will suddenly swell in summer and shrink again in winter. The seams are exposed because the wood expands with heat and contracts with cold." Shen Kuo patiently explained.

This is easier to understand, and even Mi Fu nodded thoughtfully: "When boiling water, the water vapor can push open the lid of the pot, is it also expanding with heat and contracting with cold?"

"Water turns into gas, and gas condenses into water. It's not just a change in air pressure, but another kind of force. I'm still researching this matter with Brother Zirong, and I can't answer it for a while..." At this point, Shen Kuo suddenly stopped mouthed.I saw that Mi Fu's eyes were a little bit empty, and he looked like a cloud.He couldn't help laughing, "However, the suction cylinder method is indeed due to the pressure difference caused by thermal expansion and contraction."

Only then did Mi Fu regain his composure: "Your way of making good fortune is really troublesome!"

Zhen Qiong's face darkened again: "This is the way of investigating things, not the way of fortune!"

Investigating things is the study of the nature itself, while good fortune is studying its changes. How can they be the same? !

Mi Fu pretended he hadn't heard it, and said excitedly: "Brother Boshi has been at home these few days and devoted himself to painting Baoying's performance diagram. He said it was sixteen horse-drawn horses, which inspired him."

Did this person only see marathon balls?Isn't atmospheric pressure amazing?

Just as Zhen Qiong was about to say something, Su Shi had already remembered the topic of the day, and hurriedly asked: "These days everyone is discussing, what is there in the ball when the air is drawn out? Such a big iron ball, there is no water and no air in the middle. Is it really empty?"

Hey, finally got to the point.Zhen Qiong nodded quickly: "Isn't it just a vacuum. Brother Cunzhong and I have also discussed this issue. The vacuum is the end of the world and the beginning of all things. Then get angry and evolve all things."

This is a theory that Su Shi has never heard before, his eyes lit up: "This statement is quite mysterious!"

Zhen Qiong: "???"

What does this have to do with mysteries?

However, Su Shi had already turned his head and said to Shen Kuo, "Brother Cunzhong also thinks there is a vacuum in the world?"

This has touched his hidden secret, and now it's time to uncover a corner.Shen Kuo took a light breath, nodded solemnly and said, "There should be a vacuum, but this thing is not around you and me, but above the sky. There is no atmospheric pressure, and everything is chaotic, supporting the sun, moon and stars."

Su Shi hissed lightly: "Is this what Xuan Ye said?"

He is also a person who has read hundreds of schools and is knowledgeable about the past and the present, so he has naturally heard of "Xuan Ye Shuo".It's just this way of saying that the sun, moon and stars float in the air, and their movements are driven by the air.Now it was in Shen Kuo's mouth, but it became a vacuum, and the stars floated on it.The sun rises and the moon sets, and the stars move, what is it that depends on it?

Su Shi couldn't figure it out, so he asked.Shen Kuo also shook his head: "I haven't realized this matter yet. It's just that if the stars are Qi, wouldn't they dissipate? Only floating in a vacuum can they take shape."

This is also a theory that Xuan Ye said. The sun, moon and stars are all composed of air, which can emit light and heat, but there is no solid earth, so they can float in the sky.

But how can the stars made of gas not disperse?Herein lies the paradox.However, Xuan Ye's theory can only be explained by Qi, and after all, it can't convince the public, which makes Huntian's theory become the mainstream.

Now Shen Kuo has come up with a new idea.Void is indeed "empty"!It is precisely because of this that all the stars made of gas can have a fixed shape and float in the sky.Xuan Ye, who was once discarded in the pile of old papers, also exuded a new life because of this!

For a while, Su Shi was also a little crazy, and kept stroking his beard: "There is some truth in this statement, in front of Wencai..."

Seeing Su Shi's expression, Shen Kuo was slightly relieved.Su Shi was born with a strong curiosity. When encountering unknown things, he couldn't help but study them and write amazing majestic essays.With the blessing of his wonderful pen, the theory of vacuum can spread even further, right?

The author has something to say: the suction tube method is the name of cupping in the Song Dynasty. The bamboo tube is soaked in boiling water to generate suction, but it is mainly used to treat trauma.But after a toss, it will be close to modern therapy.

Xuan Ye's theory of infinite universe, the stars are all made of gas, and gas is the origin of all things. In fact, it is quite similar to modern discoveries, but it cannot explain the trajectory of celestial bodies.
