Demonic liquid's amazing effects

After Max went to his room and closed the door, he took out his bed and sat cross-legged on it. He mediated for a while, regulating his breathing and entering a calm state of mind. Because he wasn't used to meditating, it took him more than half an hour to do so.

He then took out a bottle of 'core strengthening demonic liquid' and drank half of it, according to what Amara had told him.

"Fuck…" As the liquid entered his mouth and travelled down his throat, he felt as if he had drunk boiling hot lava and couldn't help but curse in pain. As the liquid entered his stomach, the pain caused by the burning sensation grew manifolds. Moreover, the taste was also disgusting.

He hurriedly used his mana to cover the insides of his stomach, only then the pain lessened.

'The demonic medicine is indeed different from the medicine humans use.' He thought.
