I Awakened Ancient Bloodline and Modern Abilities Due to Fever

Zhao Yu, who was born into a wealthy family, chose to run away from home because he was tired of the wealthy life. He has been suffering from fever since he was a child. One day when he had a severe fever, he accidentally discovered that he had awakened ancient bloodline and modern powers. He also inherited the legacy of the Zhao family's ancestors thousands of years ago and an immortal fire phoenix as a bodyguard. It's a pity that the bodyguards are not good enough. I always feel that Zhao Yu will not live long and is unreliable. However, even with the ancient treasures, he can only rely on his own development and upgrades to open up the legacy of his ancestors...
