Rex spent his 4th day in Planet Tioron like a man on a mission.
He was really on a mission, a mission to train under the special energy surrounding this planet and improve with it to become the perfect Blood Spartan Warrior and to become the leader of the Blood Spartan Tribe.
Just an hour of training in this planet told Rex all that he needed to stay motivated to continue jacking throughout the whole day to improve himself.
The concentration of mystic energy made training so beneficial to mystic warriors, more so to mystic warriors like Rex who was experiencing it for the first time. He was like a child, he just kept on assimilating the changes.
This time, Rex really had access to the best training conditions possible to any mystic warrior. Not only did he have the perfect training chamber for swordsmen, he also had one of the best instructors.
