Vengeful spirit of ten thousand years

"Ten-thousand-year-old vengeful spirit?" Li Tian's eyes widened. He suddenly realized something and said,""You know him?"

After a long while, the man said,"in the abyss, the spirit-sealing formation suppresses countless dark spirits. Naturally, it has accumulated an endless amount of dark energy. Over the years, it has only increased. It was originally one of the vengeful spirits of ten thousand years. However, it entered the spirit-sealing formation by chance and absorbed a lot of dark energy. It grew up until now ... The moment the spirit-sealing formation was broken, it should have escaped."

"It entered Wang Lei's body. How strong is it?"

Li Tian asked. This was the most important question.

"Ha," the man laughed coldly and said with a hint of disdain,""Even if it can't use its full strength now, it's more than enough to deal with you."
