Although Murong yuan was surprised, he slightly raised his eyebrows. "This is the crossbow machine that ah Chu is satisfied with."

Su Yunchu smiled with a smile, "not yet, but combined with the current level, I think I should be able to make such a crossbow machine. Now, it is difficult to make such a crossbow machine to my satisfaction."

Murong yuan's eyes flashed slightly, "ah Chu wants to make these in the picture?"

Su Yunchu looked at him with a smile, "how does Huaiqing feel?"

"Try it first, if you can, make plans." this is the most conservative statement. Murong yuan will not blindly indulge Su Yunchu.

Su Yunchu naturally understood the meaning inside, but looked at Murong yuan and said, "we need a trusted and experienced craftsman who specializes in making crossbow machines. Huai Qing, I want to try before returning to Beijing."

Murong yuan nodded, "well, I'll prepare for ah Chu tomorrow."

Hearing this, Su Yunchu said, "in fact, these in the picture are not the best. If you can, I think there should be plans for the next step."

Murong yuan raised his eyebrows. "What's achu's plan?"

Su Yunchu sold him a pass, "secret!"

Murong yuan smiled and said nothing, but connived at her "concealment and non reporting"

On the second day, Murong Yuan found an old man with many years of experience in making crossbow machines for Su Yunchu. Among the blue eagles, the equipment was complete. Su Yunchu only communicated with the old man and took out the atlas she had reprocessed last night. She was too familiar with crossbow machines. No matter which dynasty or generation, she was familiar with all famous ones. Therefore, There were few obstacles to the conversation with the old man.

After su Yunchu took out the design drawing, the old man brightened his eyes, "this..." he has been making a crossbow machine for decades and is constantly exploring and transforming, but he has never seen such a delicate and complex thing. Even holding the design drawing, his hands trembled slightly.

"Military division... Where does this picture come from?"

Su Yunchu looked at the old man with an excited look, and his face was still a faint smile. "I'm not talented, what do you think?"

After listening to this, the old man looked even more excited. At the beginning of Su Yun's age, it was incredible to be called a military master, not to mention the design drawing that he had never seen in his life.

But although he was excited, he didn't say much, "OK! I will try my best to see such a crossbow and make it. I should have no regrets in my life."

Su Yunchu could understand the mood of people obsessed with some things and said no more, "then please bother the old man. How about the three-day period?"

The old man bowed his head a little and pondered for a while. Then he raised his head, but he said, "can!"

Su Yunchu nodded. "If there is anything unclear in the drawing, the old gentleman can ask me."

The old man said no more, but took Su Yunchu's design drawing and studied it carefully.

In these three days, Su Yunchu spent most of her time with the old man. She didn't pay much attention to the things previously handed over to blue eagle. In fact, she hopes to make a crossbow like a military crossbow in this era, but she also understands that making such a crossbow requires great accuracy. Now, it's really difficult to do it, but even if it's difficult, She still has the heart to try.

Therefore, these days, the old man is making the crossbow machine she made according to the level of the Song Dynasty, while she is studying greater possibilities.
