In the knife skill assessment, every Immortal Chef's knife power would be tested. Based on the knife skill's power, they could see and assess the chef's strength.
Bu Fang had wanted to use Cutting Immortal Style, but after considering it, he decided not to.
Although the Cutting Immortal Style was stronger than the Overlord Thirteen Blades, he hadn't completely controlled it yet. So, if he were to use such a technique, there would be some danger.
Hence, Bu Fang used the stable Overlord Thirteen Blades.
As soon as the overlord phantom appeared, Bu Fang's power increased unceasingly.
An invisible wave of energy expanded, affecting the Immortal Chefs around him. Their power shattered at a speed naked eyes could see.
The Overlord Thirteen Blades was the technique provided by the system, so he was really confident in it. Anyway, all of his knife skills were provided by the system.
