I Have the All-Ability System

At 23, Lin Lang is reborn in 2000 and accidentally unlocks the All-Ability System, forcing him to earn money to survive. He uses the system to identify item values, making his first fortune by finding treasures at an antique market and later winning a rare imperial green jade at a gambling stone street. During this time, he meets several women including the sexy landlady Gu Keqing, high school classmate Zhou Mengyao, and the cool CEO Zhao Xeruz. He frequently clashes with the villain Zhao Longwu, foiling his conspiracy with the Morgan financial group. He also establishes Honghu Technology, launches the Hongguo smartphone, builds a vast business empire, and ultimately gains 500 years of lifespan.
