Chapter 564: End(1)
"Why didn't you save the Void beast even though he has originated from your blood?" Aakesh asked Vritrasura as when he exited the world, he only noticed two Void beasts there, whereas the Void beast at the entry point had told him that three Void beasts had entered the portal. Aakesh had promised of helping the Void beasts if he could, so he questioned.
There could only be two reasons that he didn't appear there. First, he didn't enter the world, and second, he died somewhere.
The first option seemed farfetched as when Aakesh had entered the portal; he was even weaker than the Void beasts. If he could grow stronger here fighting, then others can too. It may not be at the same rate as him, but still, they were the owner of pseudo Limitless physique.
So, Aakesh believed there was only one reason that the Void beast wasn't there. They must be dead.
