After Han Muye triggered the condensation of the Lightning Sea in the primordial world, heavenly tribulations had reappeared within the primordial times.
Those divine beasts wishing to enhance their cultivation realms needed to attract heavenly lightning.
Especially to step into the level of a Divine Beast Overlord, they had to bathe in the Lightning Sea.
Other divine beasts might not need to trigger tribulation lightning, but Wood Attribute Divine Beasts needed heavenly lightning to transform.
In the past, there were no tribulation lightning in the Desolate Wilderness, thus these wood-attribute divine beasts lacked the ability to move.
They could stand undefeated in one place, yet they couldn't extend their power and deterrence beyond their control.
Like those of the Wood Attribute Divine Beasts on Bu Zhou Peak, although they were at the Overlord Level, they could only control Bu Zhou Peak and were unable to leave Bu Taishan.
"Boom——"
