The Scarlet King noticed the look in the man's eyes, but he showed little concern. Janiro, Old River, Blue Crow, and all the others had something in common; they were all chess pieces in his mind, and their feelings and goals mattered very little as long as they followed his instructions.
"Before I go..."
A meaningful light appeared in the Scarlet King's eyes as he generated a new 9 Revolution Flame and took Slaughter and Blood Nails from his heart. Tribulation Enhancement could also be done on artifacts to improve their power.
Actually, that was the primary purpose of Enhancement since there were very few people crazy enough to do it on the body of a person, much less themselves.
The Scarlet King put the Natural Holy Weapon into the Refinement Cauldron with the Revolution Flame and triggered the Enhancement. As soon as the flames covered the weapon, the world's energy began to flood into them.
