After Zhao Zhen returned to the court, he did two major things. One was to issue an order to revise the Constitution, and the other was to confirm Xiao Ren's identity. It seemed that the latter had no effect, but in fact it was more difficult than revising the Constitution of the Emperor and Song dynasties.

Zhao Xu's actions undoubtedly helped Zhao Zhen solve a big problem. As the queen, Wang Yuyan could not object. If she said that her son was wrong, not only would Zhao Xu be affected, but Zhao Zhen would be unable to bear it.

The current situation is very happy. Xiao Tali entered Zhao Zhen's harem, and Xiao Ren was divided into the King of Chu. The people did not object to the emperor's sudden extra sons, and the focus was all on Zhao Zhen.

Even a man would not raise other people's children as his own sons. He calculated the time five years ago. It happened to be when the officials fought against the Khitan in the Western Regions, and the officials also went to the Khitan Emperor's camp for the so-called "state visit".

In this way, does Xiao Ren still have any questions about whose bloodline is?

The Khitan Emperor said at that time that the child was born by her and the gods. This is okay to deceive the Khitans, but it cannot deceive the people of the Song Dynasty. How could the gods have the ability to create humans with you, a mortal woman?

So the hot topics of the people became Zhao Zhen's health and "power".

In the secret pavilion of Chongwenyuan, Emperor Zhao Zhen of the Song Dynasty sat on a rocking chair and looked at the memorial of a master of the court. There were some drawings in the memorial. Zhao Zhen saw a conical projectile, and the black representing gunpowder was drawn behind it.

This is probably the brand new artillery ammunition they imagined. Zhao Zhen found it very interesting. This is a bold attempt to explore the unknown. The cone shape seemed very suitable for the artillery of the Song Dynasty.

Gradually, the head can reduce resistance, while the large-area tail can better fit the barrel and produce a greater bore out speed. The idea is exactly the same as the shells in later generations.

The cone that is not worth enough to later generations is columnar, but the cone proposed by the craftsmen of the Song Dynasty is a real cone. If viewed from the cross-section, it is completely triangular.

Zhao Zhen knew that this thing would not comply with the aerodynamic principles, and such a cone shape greatly reduced the loading of gunpowder in the shell.

He reached out and waved his hand in the air. Sancai on the side immediately handed over a pen with cinnabar ink. The red cinnabar on the tip of the pen was absorbed just right, not much at all, not much at all.

Zhao Zhen added a few strokes to the original cone shape, making a cylindrical shape behind the cone, and the top is not pointed but a slightly rounder shape.

By the way, the shells were marked as pellets and the gunpowder inside was marked as charge.

The artillery technology of the Song Dynasty was quite mature. It has been decades since the emergence of gunpowder to the proficient use of it. The gunpowder bullets of the Song Dynasty are no longer the trump card in the army, but they are still an indispensable existence in war.

The speed of artillery progress is changing with each passing day. This is the development of the entire scientific and technological industry of the Song Dynasty. The advancement of gunpowder technology, and the technology of iron and steel making keeps up. After producing gun steel and reloading drugs that can mature the power of artillery explosion, the craftsmen of the Song Dynasty began to study the new shape and function of artillery shells.

Artillery has always been the genius of the Song Dynasty, and the Geju Academy and the Firearms Department are directly responsible to Zhao Zhen, the Emperor of the Song Dynasty. Therefore, their every step from research to design, manufacturing, equipment of the army, etc. requires Zhao Zhen’s personal review.

Compared with large-caliber artillery, the caliber of the Song Dynasty's gun has not only not increased, but is decreasing. This is an inevitable manifestation of technological progress. Although the shells are getting smaller and smaller, their power has not changed, and they are even constantly increasing.

The shells are reduced and the loading of drugs can also reduce the weight required to carry in the army. This is an improvement, and the gunpowder in the Song Dynasty has changed from the original attack that relies on gunpowder inertia and mass to an explosion attack.

In front of the clever Song Dynasty craftsmen, the problem of changing shells to explosives was quickly solved. They found inspiration from the muskets, who fired the bullets from the bottom fire with the bullets behind the gun.

The explosion of the Song Dynasty's shells was used to use the impact of the shell head to squeeze the internal striker to detonate the internal loading of gunpowder.

The simplest reason why the Song Dynasty artillery shells changed was that the Song Dynasty artillery began to change. It had been using front-loading cannons before, but now the craftsmen of the Song Dynasty's Geju Academy have developed the rear-loading cannons.

This is thanks to the accessory provided by a plant from America, rubber.

The rubber production in the Song Dynasty had already entered a period of rapid development. Various rubbers were tried to be made, and rubber had an amazing airtightness, which seemed to appear as if it was born with sealing.

Almost all the steam engines in Dasong used rubber as a means of sealing, from the steam engines on trains to the steam engines in factories, to the bulttles installed behind the cannon, the role of rubber is everywhere.

So after everything was done, the craftsmen of the Geju Academy and the Firearms Department began to work together to improve the shells of the Song Dynasty. The cannons were reduced and no longer so bulky. The power of gunpowder increased and did not require a large amount of charge, which a problem arises.

The size and weight of the shells will change accordingly, but soon they and the gunners drawn from the army discovered that the size and mass of the shells will determine the power of the cannon when the charge is reduced and the power remains unchanged.

So an explosion of flowering shells was used, but the Firearms and the people were not satisfied. For them, the flowers were too old and the lethality was not good. So the Firearms and the craftsmen of the Jiewu Academy developed this new conical shell and creatively installed a large number of steel balls in it.

This is the result of their continuous testing. The steel balls are more powerful when they explode and have more stable flight. If they are replaced with other shapes, they will not work. The power and coverage area are not as large as the steel balls.

Zhao Zhen handed the drawings in his hand to Sancai and said: "Let the attention of the personal guards. Strengthen the escorts of the Geju Academy and the Fire Equipment Department during this period. If there is a little mistake, I will let him Zhao Li not be able to take it."

Sancai nodded and said, "I obey the order!"

After receiving the memorial, Sancai hesitated for a moment and whispered: "Official family, Chen Hong, who complained to the emperor, is still waiting in the corner hall of the palace. Do you want me to send him out?"

Zhao Zhen shook his head, took a breath and said, "Let him wait in Qingliang Hall. I will go there now. The people's hearts should not be deceived. If I don't see him, what will the people think? Wouldn't I become a king who has no faith?"

"I will send someone to pass the imperial edict now. This kid will be summoned by the official family if he receives great blessings!"
