Colin didn't have much time to think. After pondering for a moment, he quietly descended into the cavity and completely sealed off the passage behind him.
Using the last of his energy, he carefully inspected the small cave in front of him, then deployed the Silver Chamber and sat cross-legged.
"Phew!"
As soon as his body relaxed, a dark red clot of blood surged out and fell to the ground, emanating bizarre fluctuations.
Whoosh!
An orange-yellow flame immediately landed on the blood, burning it up completely.
Colin's face was as pale as Golden Paper. He took several deep breaths, which finally brought him some relief.
The translucent stream of light used by Calvin wasn't as simple as it looked. That was a Fourth Rank attack, and strictly speaking, its full power should have been even stronger than the modified Robert Explosion Skill he had used when escaping.
