From Doing Good to the World's Richest Man

From Doing Good to the World's Richest Man Plot:

Ordinary office worker Lin Xiao'an has stuck to doing good deeds daily for a decade: fixing neighbors' appliances, escorting lost seniors home, and anonymously sponsoring underprivileged students. Colleagues mocked him as a "silly nice guy" and a "modern fool", and he once stayed up at night wondering if his persistence was meaningful. Until the mountain student he sponsored grew into a top scientist and gave him all his patent earnings; the bankrupt businessman he saved recruited him as the largest shareholder when he made a comeback. As Lin's kind acts linked up one life-changing opportunity after another, he unexpectedly became the world's richest man without even noticing.
