Chapter 770: Chen Ke's Blood Letter

After hearing the truth about the Hidden Island, Zhan Yun and Yuchi Feifei felt somewhat heavy-hearted.

At this moment, Yuchi Feifei said, "No, we must rescue Brother Xu. We have been walking in the Misty Forest for so long without encountering a single gene warrior. This indicates that all of North America's gene warriors are on the Hidden Island, and there are too many of them. Once the Marquis of the Border raises the water level in the lake, Brother Xu and the others will have no chance to prevail against such an overwhelming number."

Zhan Yun also looked somber. Then, he asked Li Chan, "I heard that the Hidden Island also possesses certain fortunes that can advance one's cultivation. Can these fortunes really enhance someone's strength?"

Zhan Yun had some unrealistic fantasies. He hoped that Xu Quanyao could quickly improve his strength on the Hidden Island and perhaps hold out for a while longer.
