Chapter 710: God Phenomena

Time flew by in what seemed like a blink of an eye.

Everyone watching simply could not look away from the divine light show. None of them had even felt that a half an hour had already passed. 

It was at this time that Cain and Kali's Dao Source Cores were near their last completion. Only a few more specks of Supreme Divine Law essence would finish its evolution. 

However, before they could take the last step, an unstoppable block halted the sibling duo. 

Neither of them had even stimulated it. But the black dragon rune marking had suddenly emerged at the center of their forehead. 

At the same time, an immortal light boomed with a thunderous roar throughout the entire sky! 

'BOOOM!!' 

Complete blackness filled everything. Flashes of horrifying black electricity rippled across everything.
