Zhang Buyi looked at Wang Buyi in a daze, and then at the pile driver that was still working.

Then I remembered the process of making weapons.

When this thing is smashed down, the force must be greater than human power.

Not to mention too much, if it hits it once, it can at least stop people from hitting it twice, right?

And this thing won't get tired and will keep hitting it at this frequency.

In other words, as long as the iron can keep up with the preheating, a craftsman can forge weapons non-stop.

"King...King, you...you are really..."

Zhang Buyi looked at Wang Buxu in shock, and simply didn't know what words to use to describe Wang Buxu's wisdom.

However, the good times did not last long.

It seemed to be to resolve Zhang Buyi's embarrassment.

Only a click was heard, the water wheel continued to rotate, and the frequency continued to increase.

But the stone stopped bobbing up and down.

Looking at the sudden failure of the device, the foreheads of several craftsmen were instantly covered with cold sweat. They looked at Wang Buhung carefully while quietly checking the problem.

After some inspection, the craftsman finally found the problem, but he still said cautiously: "Your Majesty, the wooden shaft is broken. The wooden shaft is not durable. If it is used frequently, I...I think it should be made of iron or steel.

This needs to be made of steel."

Seeing the craftsmen's fear, Wang Buxian wanted to laugh but couldn't.

They are all made of wood. Don’t you know if they are used or not?

Although their external image is liberal enough, in front of these craftsmen, they are still worried about being punished after problems arise.

Therefore, Wang Buxian looked at everyone with a relaxed face and said: "Success or failure today is not important. What is important is to verify whether this method is feasible. You must write down every detail of this device and use iron where needed."
