After failing the college entrance examination and working night shifts at an Internet cafe, Li Dan's biggest dream in life is to save more money for instant noodles. Until late that night, his blood-stained keyboard was bound to the legendary [Dragon Blood Evolution System] - absorbing dragon marrow, evolving bloodline, awakening the spirit of speech, and the first appearance of the dragon body. Everyone laughed at him as a 0.37% D-level waste. Only Li Dan knew that his name was originally a dragon egg. The system is in hand, the dragon vein is shouting; the gangsters' counterattack starts tonight.
