Unlike the intense corrosive feeling from taking the Mercenary pathway's Secret Medicine, when He Ao swallowed the red reagent, he felt as if he'd forcefully ingested a red-hot piece of charcoal.

The searing heat spread throughout his mouth in an instant and followed his esophagus down into his stomach.

Then, unimpeded, the burning sensation spread from his stomach walls to his internal organs and limbs.

In this moment, He Ao felt as if numerous tiny, fierce flames were burning every inch of his body, scorching his skin and his flesh.

Right after, the massive 'flames' moved upwards along with his circulating blood, soaking into He Ao's head.

A wave of intense, joint physical and mental burning surged forth in an instant.

It was as if someone were rolling a red-hot iron rod around on He Ao's brain.

The pain was so severe it far surpassed all the physical pain he had accumulated to this point.
