When Ouyang Lishang used a secret method to engrave patterns on the magical helmet, he had shocked the group of master refiners. Ouyang Lishang had used actual actions to tell them that inheritance was very important if they wanted to refine weapons.
Refining weapons did not simply involve researching materials and using Spirit Qi to achieve resonance. It was like programming. You had to learn computer language before you could speak to the world.
The lines of power on the magical helmet were like a computer program. In Ouyang Lishang's words, it was a magical symbol.
The professional refiners faced Ouyang Lishang like a group of children facing a university professor. They were helpless and admired him.
Just like what the veteran had said, to many of them, they were obsessed with researching weapon refining techniques. If they were able to learn the truth in the morning, they would not be afraid to die at night. This was very real.
