The aura that broke through the sky retracted as soon as it was released. Chu Qing flicked his wrist and raised the tip of the sword. Looking at the rusty sword in his hand, Chu Qing frowned slightly. His vast starry eyes stirred.
This was because this sword had become new. The rust on the spine of the sword had faded a little. Although this was not detectable with the naked eye, Chu Qing could still acutely sense it because this sword had accompanied him for 300 years in that lonely world. In his heart, it was equivalent to his life.
Therefore, even the slightest change in the rusty sword would attract Chu Qing's attention, let alone the current change. The rust had become lighter, which was definitely not a good thing.
When the rust disappeared and the sword looked brand new, it would probably become a piece of ordinary iron. A large part of the reason why the rusty sword became Chu Qing's intrinsic divine weapon was because of the rust on its body.
