"Qingcheng, I can tell you without exaggeration that once this thing of yours is popularized, our Laifeng Nation will probably stand at the top of all nations!"

Hua Qingcheng nodded slightly. After all, technology is the primary productive force, and productivity determines production relations, and the economic base determines the superstructure.

The high-temperature forging problem was solved. After lunch, Hua Qingcheng entrusted Mu Lige to Mu Lanjin's care and took Zuo An up Bald Mountain. The two of them chose an open area on the top of the mountain as a place to build a kiln. Together, they built two kilns and could begin practical operation tomorrow.

"What is this?"

After finishing his work, Zuo An was puzzled when he saw Hua Qingcheng handing him a large stack of strange square things with straps on both sides.

"This is called a mask. Remember to wear it when you do the experiment."

After all, there is a lot of dust when dealing with those things, so it is better to take protective measures.

"good."

After taking the masks, Zuo An stuffed them all into his arms.

Seeing that it was not too late, Hua Qingcheng gathered some of the materials for making cement and placed them near the kiln. It was not until the evening that the two of them, each riding a horse, returned to the Hua family's old house.

"Qingqing, what is this?"

After dinner, Mu Lige saw Hua Qingcheng holding a strange pen and writing and drawing after returning to her room. She was curious. Seeing some drawings on the table, Mu Lige picked them up and looked at them.

"That's the blueprint for the bellows. I'm now drawing the blueprint for the new house."

Hua Qingcheng smiled at Mu Lige and took his hand to sit down.

In this era, there was no steel bar. For safety reasons, they didn't build multi-story buildings. Hua Qingcheng didn't have the energy to bother with that right now. She planned to build a brick house with red bricks and cement, then apply cement on the outside and do some minor renovations. The most important thing was that it was strong and durable.

"Bellows?"

It was the strange thing that Zuo An brought back from Qianyi Carpenter's house during the day. After looking at the drawings, Mu Lige's bright eyes couldn't help but light up slightly.

In the middle of the night, on the grass beside the creek near the old house of the Hua family, Moliqi, who had received the message from Haidongqing, had rushed to receive the order.

"Master, what is this?"

Seeing Mu Lige handing him a blueprint of something he didn't know what it was, Moliqi was very confused.

"The blueprint for the bellows. Go back and have someone start making it and use it in smelting. With it, not only can we save fuel, but we can also greatly shorten the forging time and refine better weapons."

"So powerful?"

Upon hearing this, Moliqi quickly folded the drawing and carefully put it in his arms, intending to go back and study it carefully later.

"That's natural."

Mu Lige looked up at the bright moon in the sky, her lips slightly raised, her bright eyes shining.

His young wife's things were naturally his, and it was only natural for him to use them.
