Zhang Qian frowned when she saw Xiang Ning's two fingers, and secretly cursed: Obscene!

The construction of cities in the north went very smoothly. By the beginning of spring, the construction of the three most important cities had been completed.

It turns out that to build a fortress, you had to dig out rocks and transport wood.

Stones can be mined on site, and large wood is scarce. Each time a fort is built, it is a huge expense.

But this time, because of the cement, only hard stones were mixed together to build a solid city.

Coupled with the prisoners in Nanliang, there was almost no consumption this time.

Daming Palace.

The empress sat on the phoenix chair, and Bai Qiulian, the Minister of War, was reporting on the construction of the city in the north.

"The construction of the seven fortresses in the north has been completed, with a total cost of 1 million taels of silver and the recruitment of 10,000 laborers."

The empress looked at the memorial and said: "The seven fortresses in the north were built by the previous dynasty. They have been built for more than 50 years. They have always wanted to rebuild them, but because of the treasury, they have never started."

"This time Long Chengen invented the magical powder, and with the help of Nanliang prisoners as coolies, it only took 5 months to complete the construction. This is a great achievement."

"Long Chengen solved the problem of burning firewood and rebuilding the fortress, and he was responsible for his duties as Minister of Industry."

"Long Chengen."

Long Chen came out and said, "Wei Chen is here!"

The empress announced on the spot: "Today I officially appoint you as Minister of the Ministry of Industry, with an official position of the third rank."

Long Chen bowed and said, "I would like to thank God for His kindness."

Yingfeng held a seal ribbon, which was the official seal of the Ministry of Industry, and walked up to Long Chen.

"Congratulations to Long Shangshu."

Yingfeng smiled and gave the seal ribbon to Long Chen.

"Thank you."

Long Chen accepted the seal ribbon.

From today on, Long Chen officially became the Minister of Eastern Zhou Dynasty.

"What else?"

The empress is in a good mood at the moment.

At this time, Jing Heng, the Minister of Household Affairs, came out, his eyes flashing like the eyes of a mouse.
