the name of the this volume is Nexus of Death, so i think that Wang Wei will die from this confrontation, but at the last second or something comprehend a Dao or a way to cheat death, or maybe release a few of his seals in his soul and create another attack that resonates with his paragon soul that will be strong enough to bypass the enemy's Op dao. Although it is very cliche, the guy is literally his nemesis, and i would not find it surprising if he did not have 1 or 2 Chaos treasures, along with several Innate treasures that can perfectly counter Wang Wei, like the mirror.
Although it would be nice if he became a fateless person, i dont see how that would help him in this situation. Its not like if he became fateless that his enemy would instantly lose intest in Wang Wei and on his revenge like an Npc would. i honestly have no idea on how WW will survive the test, hopefully on tomorrow's chapter we will have an answer
