The craftsmen that Zhao Hai had sent to the secret plane were all the best craftsmen in the city, and some of them were even talented apprentices. He had even asked the city to hire some skilled craftsmen from other cities and send them to the secret plane.
After coming to the secret plane, although the craftsmen had a hard life and had a lot of work to do every day, Zhao Hai was still very good to them. He only allowed them to work ten hours a day, no longer. However, the craftsmen had to take turns. The craftsmen could rest, but the work in the equipment refining room would not stop.
The blacksmiths actually liked the place. The black and white of the secret realm were distinct, and everywhere was green. They didn't have to worry about food and drink. Zhao Hai didn't limit their freedom too much. Although they didn't see many people here, they liked the environment.
