Daming: I really don’t want to be an emperor!

Most importantly, Zhu Yunhuan wanted to meet Zhu Di.

Meet the future Yongle Emperor Zhu Di and Prince of Ning Zhu Quan, who were instrumental in bringing about the rebellion.

Zhu Yunhuan, the King of the Frontier, was not worried about other people, but he was worried about these two guys because they had heavy troops under their command and were both brave and resourceful.

"Okay, I will make arrangements immediately and send an urgent message of 600 miles to notify the princes to return to Beijing to participate in the enthronement ceremony." Feng Sheng heard the hidden meaning in Zhu Yunhuan's words.

By calling back the princes, Zhu Yunhuan might be planning something big.

Zhu Yunhuan then continued to head to the arsenal.

Look at the true situation of this new type of artillery. In the Ming Dynasty, cannons are the sharp sword of the imperial court!

To forge a cannon is to forge a sharp sword for the imperial court, which will be invincible wherever it points!

"His Royal Highness Taisun has arrived!"

Accompanied by the eunuch's loud shout, Zhu Yunhuan also stepped into the arsenal.

"Long live His Royal Highness the Crown Prince."

Everyone saluted.

Zhu Yunxun gave him a false helping, "No need to be polite."

"Thank you, Your Highness." Everyone expressed their gratitude.

Zhu Yunhuan looked at Qin Shou, "Why, didn't you sleep well these past two days? Why are your dark circles so heavy?"

Qin Shou bowed and said, "I am honored by your majesty's kindness and I dare not let you down. After many attempts and improvements, I finally made a new cannon, and it has passed the test firing, that is..."

"What is it?" Zhu Yunhuan asked. Is there any other problem?

Qin Shou replied, "It's just that the sound is a bit loud. When I tested it before, I directly called the Imperial Guards. But the sound was very loud and the power was also very strong. The abandoned palace wall was blown down by a single shot. The power is far greater than that of the Hongwu Cannon."

Zhu Yunhuan waved his hand, "I thought it was something else, but it's just this. It's okay, take me to have a look."

"As ordered, Your Highness, please follow me." Qin Shou led Zhu Yunhuan through layers of checkpoints and entered an open space. This was the city wall of the imperial city, and outside the wall was the palace.

Once you get out of the city wall, you will be out of the palace.

Behind this city wall is a small forest, which is specially used for testing the Hongwu cannon.

When everyone came out of the palace wall and the city wall, they saw a very majestic cannon standing outside. Zhu Yunhuan recognized it at a glance. These guys really made the red cannon.

I simply modified the structure of the red cannon and combined it with the new cannon they were researching. The combination of the two really turned it into a red cannon.

This is the cannon that was introduced to the Central Plains in the late Ming Dynasty.

Now it’s out ahead of schedule.

"What's the matter with this cannon?" Zhu Yunhuan looked at Qin Shou.

Qin Shou immediately introduced, "Your Highness, after your improved drawings, this cannon was created. Its advantages are that it has a long barrel, thick wall, large caliber, and the overall shape gradually thickens from the muzzle to the breech, which fully complies with the principle that the chamber pressure decreases from high to low when gunpowder burns.

There are cylindrical horns on both sides of the center of gravity of the gun body. The gun can adjust the shooting angle with this as the axis, and change the range by adjusting the amount of gunpowder used. It is also equipped with a front sight and rear sight, and the trajectory is calculated according to the parabola, with high accuracy.

This new type of artillery is nine feet long, thirteen centimeters in diameter, and weighs two thousand pounds. This is also a disadvantage. A two thousand pound artillery is too thick. Although it is powerful, it is difficult to move and consumes more resources. "

Qin Shou introduced this new cannon to Zhu Yunhuan.

Zhu Yunhuan nodded, "It's better to be thicker, it's more powerful."

"Your Highness, it's good to be thick, but it's inconvenient to move, and the demand for iron ore is even greater." Qin Shou replied.

Zhu Yunhuan waved his hand, "It's okay. All the iron will be supplied to your arsenal first. Now fire a cannon, aim at that hilltop, and let me see the power."

"Yes, Your Highness, please cover your ears later. The noise is a bit loud." Qin Shou reminded and then ordered people to fire.

Zhu Yunhuan nodded. He also knew that this thing might be really loud and not as light and convenient as in the future. Zhu Yunhuan covered his ears this time.
