Cheng Rui left the first floor of the Creation Master Association silently and immediately headed for the breeding room where his grandfather was in seclusion. Just as he was hesitating to open the door and call for his grandfather, his face revealed a complex expression. It was a mix of resentment and fear.

Cheng Rui didn't expect that his grandfather would end his seclusion at this moment. He quickly greeted, "Grandfather, after this seclusion, your hair is now completely black. It is another progress!"
The elder laughed, but his laughter contained a little feminine tone. "During this seclusion, the Gold Ring Spine Gu has upgraded from Fantasy IV to Fantasy V. I didn't waste ten years of effort for nothing!"
