Fang Heng traveled through time and came to a world where demons were troubled and ghosts were rampant. More importantly, his qualifications are average, but fortunately his body has mutated. "Ding, your Ji Yuan Body Tempering Technique has reached the basic level. Your stomach has been fused with the Ji Yuan Body Tempering Technique and mutated. From then on, your digestive power has greatly increased and you can better absorb the essence from food." "Ding, your heart has been fused with the Blood Flame Technique. From then on, your heart is like a volcanic furnace. The blood energy explodes and burns fiercely, out of control." "Ding, your kidneys swallowed one yuan of heavy water and mutated. From then on, you have the power to refine your body and be invulnerable to all poisons." … "Ding, your blood is refined into a drop of dragon's true blood. From then on, your blood energy and strength will greatly increase, and you will have the ability to transform into a dragon." Countless years later, Fang Heng looked back and realized that he was already invincible. "The fact that I have such high strength is really earned through hard work." Fang Heng whispered.
