At the beginning of the ancient times, thousands of tribes invaded the Tianyuan Continent and demons were raging. The human race was treated as blood-eating livestock by all races and suffered terribly. However, there was no end to the human race. A young human race boy named 'Xuan' was adopted by the dragon race since he was a child. After several years of observation, 'Xuan' discovered that every time the dragon race breathes, a special kind of energy from heaven and earth enters the body and continuously strengthens the dragon race. On his own, 'Xuan' called this energy 'Yuan Li' and based it on the breath of the Dragon Clan. After a few years, he created the first technique in history to absorb vitality, 'Na Yuan Jue'. He later left the Dragon Clan and passed down the 'Na Yuan Jue' to lead the human race to fight against all races and slay the demons, laying a solid foundation for the rise of the human race. He was later named the 'Human Emperor' by the human race. My name is Mu Yunsheng, and I am a time traveler. I am very excited to own the system.
