Not a transmigrator

Dashing a considerable distance away from Astin into a dark, hidden alley far away on the outskirts of the city.

Andrew fell to his knees, breathless. Black mana ever remained gnawing at his inside.

He puked large amounts of black matter; his immune system functions to compel impurities.

Ryan watching him on the side wasn't fairing well either.

Although he only used a downgraded, nothing but a mere imitation version of Hiro's power to fool Astin, it took a toll on his body while he was still in recovery mode.

Nonetheless, seeing how the black mana failed to corrode Andrew's soul, Ryan was surprised. The sight in front of him serves to show that a world law user, no matter the odds, cannot be killed by a regular mana or radiation user.

However, Andrew himself could not be considered a world law contractor.
