The level Song Shuhang was at was still very far from 'eternity'. When it came to anything related to 'eternity,' he could only brainstorm as to what it might look like.
However, when he saw this small bone, the concept of 'eternity' emerged in his mind on its own.
"In the entire universe, isn't the Wielder of the Will the only thing that's supposed to be truly eternal? What is with this piece of bone from Fairy Skylark, then?" Song Shuhang was puzzled.
Could it be the source of Fairy Skylark's immortality?
"Crackle~"
In the sea of lightning, the countless light cannons continued to bombard the small bone. The bone seemed to be simply taking a bath. It did not receive any damage, and it actually became smoother and brighter instead.
After bombarding it for another 10 seconds, the heavenly tribulation stopped.
