"promise!"
Seeing Liu Deng's tired look, Shunzi responded and hurriedly retreated.
"Your Majesty, are you looking for me?"
A few moments later, Cai Xin came to Liu Deng's study in a hurry.
"How is your research on the artillery issue? Have you made any breakthroughs in the past two days?"
After Liu Deng asked him to sit down, he was served tea, and then he asked.
"There is still no good solution, we are still trying..."
When he said this, Cai Xin was really ashamed. In just a few days, he had spent tens of thousands of dollars, but he had gained nothing.
"If I give you three days, can you possibly make a pure copper cannon?"
Liu Deng said with a frown.
"It is possible, and it can guarantee that at least ten rounds will be fired, and the chamber will definitely not explode within ten rounds! It's just that the cost of this thing is too expensive, and it has no practical significance at all..."
There is certainly no problem with the performance of a cannon made of pure copper. The only problem is that the cost of making this thing is too high!
An artillery piece easily weighs tens of thousands of kilograms. If converted into money, it would be at least fifty or sixty thousand kilograms.
If this thing was equipped on a large scale, even Liu Deng wouldn't be able to afford the expense.
"Don't be afraid of spending money. I need a heavy cannon that can shoot more than five miles. Can you complete it in three days?"
Liu Deng looked at Cai Xin seriously. This thing will be exposed sooner or later, and as long as he can keep the secret of gunpowder secret, they can't make it even if they give the drawings to the Huns!
Besides, with the national strength of the Huns, if they really wanted to build artillery, they would fall into Liu Deng's trap.
The fighting methods of the Huns and the Han Dynasty are completely different. All the Huns are cavalry, so they can come and go erratically like the wind.
But once they carry such heavy artillery, their traveling speed must slow down.
If this happens, their biggest advantage will be gone.
As for the three countries of Nanyue, Dongou, and Minyue, Liu Deng has now begun personnel training.
Attracting their attention to artillery and shipbuilding would be of great benefit to Liu Deng's next plan.
So after Liu Deng thought about it, he decided to use this thing that was still in the experimental stage to shock people.
"promise!"
Cai Xin didn't know what Liu Deng was thinking, but he had an advantage. As long as Liu Deng could do it, he would never ask more questions about the reason.
"In that case, I will be waiting for your good news in three days!"
"promise!"
Cai Xin responded, then turned around and went out.
Liu Deng then returned to his dormitory and was about to leave again, and it was already the end of October.
After entering Beijing this time, it would probably be the first month before he came back, and Liu Deng felt really uneasy.
"Your Majesty, what's wrong with you?"
Seeing Liu Deng's tired look, Liu Ruyan quietly came up and reached out to help Liu Deng press the temples on his head...
"You clean up in the past two days, and come to Beijing with me this time!"
Liu Deng closed his eyes and whispered.
"Slave..."
When she thought of staying and flying together with Liu Deng, Liu Ruyan felt like she was dreaming.
But she was a little afraid in her heart. She really didn't know what kind of woman the queen she had never met was...
After all, she came from a humble background, and she was really afraid that the queen would be difficult to get along with...
"I know what you are thinking. In the final analysis, I am sorry for you. This kind of thing should be done wholeheartedly, but I am too greedy..."
Liu Deng's voice was very calm, but these simple words made Liu Ruyan's eyes feel a little red...
"Your Majesty, I will follow you to the capital..."
After carefully wiping away the tears from the corners of his eyes, Liu Ruyan said firmly.
Asking herself, she sees quite a few men in this world, especially those noble sons from aristocratic families.
Including Liu Yishui, in terms of appearance, there are indeed many people who are better than Liu Deng in appearance, but women have always been just playthings in their eyes.
How can there be a person who respects her so much like Liu Deng...
In the huge palace, only Liu Ruyan and Liu Deng were left.
Liu Deng reached out and held Liu Ruyan's hand, and took her into his arms somewhat roughly.
"Don't move. I'm a little tired. Let me rest for a while..."
Liu Ruyan was originally worried about Liu Deng's next move, but unexpectedly Liu Deng simply hugged her and closed his eyes...
Her somewhat stiff body slowly softened. Feeling Liu Deng's gentle breathing behind her, Liu Ruyan was immersed in happiness...
In this life, if you get a son-in-law like this, what else can you ask for?
When Liu Deng opened his eyes again, the sun had already set.
"Your Majesty, Mr. Chao is ill..."
Liu Deng had just stepped out of the palace and came to report with a strange look on his face.
"sick?"
Liu Deng was stunned for a moment, and then he realized that Chao Cuo was really cautious in handling things now.
"In this case, let's go find the imperial doctor and give him a good look, and tell the imperial doctor that Master Chao has had a hard time traveling all the way. He must have become ill from overwork, and it will take him two or three days to recover!"
A smile appeared on Liu Deng's lips, then he patted Shunzi on the shoulder and said.
"promise……"
After all, Shunzi is a straight person and doesn't quite understand what Liu Deng means.
Although he had some doubts, he still turned around and went to find the imperial doctor.
Since Chao Cuo was ill, the matter of catching the wind was naturally avoided.
Liu Deng simply returned to his study again and wrote down several things he wanted to do next.
Liu Deng could only leave all the issues of sweet potato promotion and storage to Chen Qi to prepare.
Fortunately, it is going to snow soon. Judging from the situation this year, the Huns should not be able to worry about invading the other side.
As for the issue of the Prime Minister, at this time, Liu Deng could only hope that he could communicate smoothly with the emperor, and then promoted Feng Jing.
The third day of November is a good time to travel.
Chao Cuo, who had been ill for three days, finally got up today.
Fortunately, Liu Deng was finally ready.
The two looked at each other and smiled, saying nothing.
"Since Mr. Chao is already well, I think we should get up and set off today! Your Majesty must be waiting impatiently!"
"What the king is saying is that I'm just too weak and it's causing trouble for the king!"
Chao Cuo also raised his hands towards Liu Deng and said.
"What are you talking about, sir? No one will get sick if he eats whole grains. Everything is ready here. Let's set off now!"
"Your Majesty, please!"
