Bab 1401: The Trump Card.

It is not a suitable condition for one who is about to undergo tribulation. Fortunately, he has divine life energy. Thanks to Legion-9, he will be in the best condition for his tribulation by the time he reaches the void. 

"We have to survive this," Legion-5 said and all of Legion agreed. 

They have invested a lot into Legion-5 so he must survive the tribulation. For that purpose, back for this tribulation. 

Not only will he surely die if he fails but so will Legion-7. Legion-7's death will mean that Legion-1, Soverick, Ragnarok, and the tree father will also die. That is 6 out of 9 of them dying at once. That is a massive loss to Legion even if it is temporary. 

They will be resurrected by the void universe since they are Origin god's now and the Tree Father can be saved through the soul sphere. But Legion-7's death might be permanent. After all, the void universe will never allow him to exist again.
