"Are you a traitor? I'm at your level, don't embarrass the traitor! ”

Zong Shu felt that Cai Xiu was a little overwhelmed.

The "Six Traitors of the Northern Song Dynasty", which was recognized by later generations, were all first-class masters, and their level was all leveraged.

At Cai Xiu's level, as soon as he was admitted to the Jinshi, his tail was cocked to the sky, thinking that he could be on an equal footing with his grandfather Cai Jing.

actually called yourself a traitor, Cai Xiu, you are embarrassing the traitorous ministers.

also said that what is a traitor personally sealed by His Majesty, no matter how mediocre Huizong is, he will not be able to play with such a name.

"Young Master Zong, I have participated in the examination, and I am a dignified jinshi and so on, why can't I be appointed as the eunuch of the country?" Cai Xiu was very strange.

Guozi Jian Cheng? No... Traitor?

It turned out that Cai Xiu was awarded the post of eunuch by His Majesty, but Zong Shu heard that he was a traitor.

The term so-called traitor did not appear until after the Yuan Dynasty.

Before the Song Dynasty, the ministers who misled the country were called tyrants or ministers.

……

Zong Shu walked out of the hall and couldn't help but get angry, he was so busy during this time that he didn't even have time to go to the Qinglou to eat flowers and wine, and he was delayed by Zhao Kai for half a day for no reason.

Rushing back to the Great Song Academy of Sciences, Zong Shu found Lin Lingsu again.

After Zong Shu's loud shouting in the court, the horn he had just made was deformed and lost his voice.

In order to make a loudspeaker, Zong Shu asked Lin Lingsu to find a few people and give everyone a special lesson on sound.

The propagation of sound mainly depends on vibration, and the human voice mainly depends on the vocal cords.

After talking about the basics, Zong Shu drew another sketch, which is the core component of making a horn: the diaphragm.

There are four types of diaphragm materials: paper cone, plastic, metal and synthetic fiber.

Paper cone diaphragm is the earliest and most common speaker diaphragm material.

To make the paper cone diaphragm, the pulp should be poured into the designed mold first, and then a series of subsequent processing should be carried out after drying.

The sound characteristics of this diaphragm are smooth and natural.

The disadvantage is that the paper cone is sensitive to temperature and humidity, and is obviously affected by the environment, and may produce irreversible deformation after withstanding several extreme environmental changes.

After Zong Shu drew the drawing, before the mold could be made, Lin Lingsu went to the paper mill to order special paper.

It is the kind of brittle white bamboo paper, and the effect of vibration is better.

The main function of ordinary rice paper is to reduce sound, and it cannot be felt even if there is vibration.

Through the vibration of layers of bamboo paper, the most primitive paper cone diaphragm can be made.

A horn was made from Lao Feng, a porcelain workshop, and the paper cone diaphragm was installed in it.

The amplification efficiency of this kind of speaker is far worse than that of later speakers with batteries.

Even if the horn is so primitive, it is enough to shock everyone.

It is not difficult for Lin Lingsu to understand that this horn is equivalent to the shape of people who put their hands together in front of their mouths when they shout.

It's just that this horn has an extra paper cone diaphragm. With just such a small device, the human voice can be amplified several times.

Everyone is convinced, the teacher of the national teacher is different, and any thing can have amazing effects.

Zong Shu was very dissatisfied, this horn could only make the ancients drop their jaws, and in modern times, it could only make people laugh off their big teeth.

In terms of materials alone, plastics, metals, and synthetic fibers are not yet available.

Plastic has to be refined from petroleum.

If you want the speaker to amplify the sound without distortion, you must use electricity!

Just to make an electric horn, you have to use magnets and inductance coils.

There are magnets, inductance coils can also be made, and the copper process of the Great Song Dynasty is also relatively mature, and the copper wire is coated with lacquer, and it becomes enameled wire after many baking.

The most important thing is to make a battery.

Just such a small electric horn, to make it, requires too many processes and materials.

Not to mention making a simple DC generator or the like.

Zong Shu believes that rejuvenating the country through science and technology can completely overtake in corners.

The invention of the steam engine started the industrial revolution of mankind. Soon after, the invention of the electric generator greatly accelerated the process of the industrial revolution.

In terms of the current level of science and technology in the Great Song Dynasty, the difficulty of manufacturing a steam engine is far less than the difficulty of manufacturing a generator.

Watt's invention of the steam engine was based on water vapor to open the lid of a teapot, which was the first combination of science and technology.

The materials and processes required to make the generator do not exceed the steam engine, but the principle of inventing the generator is more complex and abstract.

The generator must be guided by the most basic and lowest theory, and if you don't understand the theory of electromagnetic induction, it is impossible to build it.

As long as a steam engine can be built, then it is not a problem to build a generator.

Because, Zong Shu understands the theory, especially the theory of electromagnetic induction.

Then, you can do it in one step and directly engage in generators.

Zong Shu immediately started and began to compile "Fundamentals of Electricity", and taught it himself.

All this, the reserves of the Great Song Academy of Sciences are very small. At the end of the day, there are still too few talents!

If there are more people like Su Yi, everyone can tackle key problems separately.

Hiring! Keep hiring! Zong Shu gave Lin Lingsu an indicator.

At the same time, Zong Shu ordered Lin Lingsu's glass workshop to make a few things and hand them over to him within a month.

After explaining the task, the crown prince Zhao Huan suddenly came, and he was accompanied by Wu Fei.

Wu Fei sighed when he saw Zong Shu, Zhao Kai listed Zong Shu's big crimes, and so many civilian officials concentrated their firepower to attack Zong Shu.

But Zong Shu didn't do anything at all, but scolded Zhao Kai and dozens of officials so much that he couldn't raise his head.

Zong Shu held a thing shaped like a blow needle in the court, which could expand the volume, and it was this equipment that helped Zong Shu win a verbal battle.

When this news came out, it changed its taste, and it was rumored that after Zong Shu robbed the law field, he took a blow needle and made another big fuss in the court.

After Zong Shu came out of the Zichen Palace, Zhao Huan made a suggestion to let the seed master Dao be the prefect of the daimyo, and let Zong Ze be the prefect of Puzhou.

Cai Jing raised objections, he believed that the failure of the Northern Expedition to Liao was mainly blamed on Tong Guan, but the cultivation of the master itself also had a big problem.

Zong Shu also said that the seed master was too arrogant and did not take the Liao people in his eyes, which led to various improper responses by the seed army.

Although it is a kind of demotion to let the Seed Master Dao be appointed as the prefect, this Daimyo's Mansion is the gateway city to the northern border of the Great Song Dynasty, and it is very important not to let the Seed Master Dao come here.

As for Zong Ze, he is also very old.

Besides, Zong Ze was dissatisfied with the imperial court's policy towards gold at that time, and now letting him go out of the mountain, doesn't it mean that the imperial court's policy has changed?

Cai Jingjing should oppose any opinion put forward by the crown prince, and he is a staunch supporter of Zhao Kai, the king of Yun.

Zhao Huan sighed in his heart, the grandmaster gave such a task, but he did not complete it.

When he was frustrated, Cai You suddenly supported Zhao Huan's proposal, thinking that the prince's proposal was very right.

Cai You said that Liang Zimei, the prefect of the Daimyo Mansion, colluded with Zhao Gou and Tong Guanxin in the process of the Northern Expedition this time to jointly entrap the family army.

Liang Zimei detained a lot of the military supplies transported by the Privy Council, especially iodophor, resulting in the seed army not having a bottle of iodophor.

Cai You and Cai Jing, the father and son, actually disagree in the court!

At that time, Cai Jing was so angry that his face turned pale, and it was understandable that others opposed him, and Cai You was his eldest son, wasn't this open infighting?

When Zhao Huan said this, he couldn't help but ask Zong Shu, why did he predict two months in advance that Cai Jing and Cai You would definitely turn against each other?

Lin Lingsu also knew about this matter, Zong Shu said at the time: In the face of power and interests, no one is calm.

Cai Jing and Cai You will definitely turn against each other and turn against each other.

Looking at it now, Zong Shu proposed to let Cai You serve as a member of the Privy Council at that time, not at all to please the Cai family, but to nail a nail in the Cai family.

It was this nail that made the Cai family's plank crack.
