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

"Tao Guangyi? But he is the principal of Tao Family Academy in Wucheng, Zhejiang, the Tao Guangyi who wanted to fly and failed?" Zhu Yunheng's eyes lit up.

This person is the first person in ancient astronautics.

Although it failed.

"That's right." Qin Shou nodded.

Zhu Yunxun smiled when he heard this. "I agree. From now on, we will separate the manufacture of firearms from the Arms Bureau and set up an arsenal. You will be the first director and be fully responsible for all matters related to the manufacture of firearms. You will be a fifth-rank official!"

"Thank you, Your Highness. I also have a blueprint for an improved version of the firearm to present to you. I beg Your Highness to approve it. This blueprint solves the shortcomings of the Hongwu cannon. It is even more powerful and more convenient." Qin Shou breathed a sigh of relief.

Fortunately, he was not dragged down and chopped.

Zhu Yunxun asked, "Where is the blueprint?"

"Here is the blueprint." Qin Shou took out a blueprint from his arms and handed it to Zhu Yunhuan.

Zhu Yunhuan took it and unfolded it to have a look.

Pupil was startled, "Isn't this the Red Cannon? Where did you get the blueprint?"

"Red Cannon? I don't know. This is a new type of cannon developed by me and my fellow apprentices. We have proposed it to Eunuch Li many times, but it was always rejected. They said that cannons are the country's most important weapon and cannot be tampered with by a commoner like me. If there is a problem, I cannot take the responsibility, etc." Qin Shou replied.

Zhu Yunhuan took a closer look and said, "No, this is not the Red Cannon. It looks very similar, but it seems to be thicker than the Red Cannon. How far can this thing shoot?"

"Your Highness, according to estimates, the longest range is about twenty to thirty miles, and definitely more than ten miles." Qin Shou replied.

"Bring pen and ink." Zhu Yunhuan ordered.

"Yes, Your Majesty." The eunuch beside him took the order and quickly went to get pen, ink and table.

Zhu Yunhuan began to make some changes to the drawing.

According to the structural modifications of the Red Cannon from memory, Zhu Yunhuan was very knowledgeable about ancient artillery and even made one by hand at that time.

Then before he had time to carry out the experiment, he was dragged away by the people above.

After Zhu Yunhuan made some revisions, he handed it to Qin Shou.

"Look, if we do this, will this cannon be more stable? Will the range be longer? Will the power be greater?"

Qin Shou took the drawing handed to him by Zhu Yunhuan, looked at it carefully, and then started to make detailed calculations on the ground.

When Zhu Yunhuan saw Qin Shou kneeling on the ground and scratching with a stone, he remembered that he had not yet asked this guy to stand up. However, Zhu Yunhuan did not say anything after remembering it to avoid disturbing this guy.

After about ten minutes, Qin Shou showed a look of surprise.

"Your Highness, if this artillery is improved in this way, the overall performance will indeed be greatly improved. Your Highness is truly a talent!" After detailed calculations, Qin Shou found that it would indeed be better.

Zhu Yunhuan nodded slightly, "Get up, I promise you can come to see me anytime, I will pay you if you want, you can recruit people by yourself, you can also arrange people to buy materials by yourself, I will pay for it, as long as it is your request, I will grant it."

"Thank you, Your Highness. Thank you, Your Highness."

Qin Shou kowtowed three times to Zhu Yunhuan before standing up.

"How long will it take to build a door? I want to see the sample and the actual effect." Zhu Yunhuan asked.

Qin Shou replied, "Three days! I'll work overtime, so the day after tomorrow will be fine."

Zhu Yunhuan nodded, "Okay! When this new type of artillery is ready in three days, you should have someone inform me immediately. You should now submit to me as a vassal."

"Yes, Your Highness, I... no, I obey your order."

Qin Shou bowed.

Zhu Yunxun reminded him, "But, after one month, if you don't deliver the data you said, or if you cheat me by cutting corners, then you are a criminal who deceives the emperor! For the crime of deceiving the emperor, all nine generations of your clan will be executed!"

"As long as Your Highness can give enough money, if I fail to complete the task on time, Your Highness does not need to blame me. I will go and ask my nine clans to ascend to heaven myself!" Qin Shou immediately assured Zhu Yunhuan.
