Zhao Huan stroked Roujia's head indulgently.

Zhao Chen on the side said: "Dad, the steam locomotive is too bulky, and the child thinks it is not very useful, so why do you have to spend so much manpower and money to make it? The child can't figure it out."

Zhao Chen is twelve years old this year. At the age of curiosity about the world, he has also begun to have some of his own ideas.

Zhao Huan said seriously: "Chen'er, I ask you, two thousand years ago, what kind of bows and arrows did people use to shoot white deer?"

"The workmanship is rough, and the arrows may be stone."

"What about now?"

"Strong crossbow, even divine arm crossbow."

"No, now I have started using muskets." As he said that, Zhao Huan took out a short flintlock rifle.

This flintlock rifle is engraved with cloud patterns, which looks very exquisite.

"Chen'er, remember that everything needs to be constantly improved, not very good from the beginning." Zhao Huan poured a glass of wine for his son, "The steam locomotive is running slowly now, which does not mean that it is still very slow in a year, and it does not mean that the speed cannot exceed the horse in three years!"

"Boy remember!"

"Since the steam engine can push the turbo, it can push the ship. King Kang's naval warships will have to be equipped with steam engines in the future. Not only that, the artillery must also be installed on the warship!"
