At the same time the Undying Devouring Sky Beast Avatar hid within the Chaos Divine Palace.
Xu Nian himself experienced earth-shattering changes.
Initially, as Xu Nian and his team continued mining, they obtained a large amount of Rock Iron Energy Metal.
Xu Nian's physical strength also improved rapidly.
In the end, Xu Nian absorbed nearly six hundred thousand tons of energy metal to reach a state of bodily saturation.
As such, Xu Nian's physical strength directly reached a level comparable to the Peak of Heavenly Gang Realm.
It's worth noting that Xu Nian's cultivation was only at the Peak of Cave Void, and his Body Cultivation had only just reached the Wanxiang Realm, yet his physical strength was at the Heavenly Gang Realm level.
This was simply a defiance of the heavens.
With the addition of Divine Demon Energy, Xu Nian could completely crush late-stage Heavenly Phenomenon Realm experts.
This crossed nearly two major realm levels.
