A cage, a huge cage!
The Sky Prison Valley was a cage to begin with, but no one knew that apart from being a cage, the Sky Prison Valley was also a supreme treasure, a supreme treasure controlled by Daeva Warden.
Even a Supreme Daeva would be suppressed and killed by him!
Infinite pressure converged on Lin Feng. Daeva Warden smiled sinisterly. "How can a mere Titled Daeva like you know how powerful I am? I'm not afraid to tell you why there are so many Daevas imprisoned in the Sky Prison Valley. I am using them to study bloodlines. Moreover, all these years, I've been relying on them to strengthen the bloodline in my body. One day, I will definitely be able to strengthen my bloodline to the level of the Progenitor's bloodline!"
Boom.
Daeva Warden took a step forward. Even the void seemed to be shaking. Infinite pressure piled on Lin Feng's body, crushing down like a mountain.
