章 46: Chapter 46 Spirit Swallowing Formation

A two-inch silver black flying knife gripped in his palm, Zong Shou generously injected spiritual energy supported by true qi to wash through the flying knife.

Pretty much every half an hour, Zong Shou would absorb a beast spirit stone and beast crystal to replenish the true qi and spiritual energy in his body.

He also rubbed a special beast oil on the body of the knife to prevent this flying knife from being damaged by the purification and training of true qi and spiritual energy.

The flying knife in his hand was mainly fine steel, however the supporting materials were not just red copper, as there was also obsidian and some black iron.

The knife body itself was also slightly wider than the Willow Mark flying knife from before. Although it was slightly uncomfortable, he was still barely able to use it.
