With that said, Cheng Jing took out a very small paper bag from his arms, popped it open, and placed the powder inside in front of Zhou Yu: "Your Majesty, this is gunpowder reconstituted according to the method in your Majesty's booklet. I have already prepared it."

It has been tested in the workshop. It is far more powerful than the gunpowder we used before. Tomorrow there will be craftsmen to test the explosive bags and grenades. I have already made people watch and report any news to the emperor as soon as possible.

."

"Okay, okay!" Zhou Yu laughed and said, "These craftsmen are really amazing, they must be rewarded."

Cheng Jing nodded, a little puzzled: "Your Majesty, I already know the usefulness of this gunpowder, but what is the use of this cement?"

"This is a good thing." Zhou Yu smiled and ordered: "Xing'an, go find some gravel and river sand and bring it back. Then call a craftsman over and be quick. I will let you see what this cement is like later.

What's the use?"

"Slave, go right away."

Zhou Yu knew that cement could be made quickly, but he didn't expect that Cheng Jing would bring back the finished product so quickly. Not only did he make the cement, but he also adjusted the new gunpowder. Zhou Yu took a look at Cheng Jing's belt.

When the sample comes back, you will know it tastes right.

"Let's go to Qianqing Palace."

Soon after, Xing'an brought things and craftsmen to the Qianqing Palace. Then, under Zhou Yu's command, the craftsmen mixed the cement and sand together with water in proportion, and then divided the mixed cement mortar into several pieces under Zhou Yu's command. One portion was placed directly in the barrel, another portion was filled into a small hole on the ground, and the last portion was made into a square stack about thirty centimeters wide and tall, framed by a template. .

Everyone couldn't understand what it was, but it didn't affect their understanding of what to do. After everything was done, Zhou Yu asked Xing'an to reward the craftsman with ten taels of silver, send him a bath, and take good care of him.

It is true that this means taking good care of him, but in fact it is also a disguised form of imprisonment. The craftsman also understood what the situation was and was taken away after thanking him. The next period of time was just about eating and drinking, resting and enjoying it. , whether it is a fortune or a disaster depends on how big the secret is.
