After going through the sword crystal's modifications, the Thunder Light Sword Skill had become stronger and stronger with each successive move. The attack that had directly killed three people in a second was the Thunder Light Sword Skill's seventh move.
After exterminating those three martial artists, all of the body refining sixth level martial artists had been cleared out by Leo. Next up, he would be facing body refining seventh levels.
Taking a deep breath, Leo did not delay and took another step forward!
After going through the Thunder Light Sword Skill's first seven moves, currently, Leo's accumulated power was at its peak. The next move would be the last one and would be a thunderbolt attack.
