Fusion System: Rebirth in a Courtyard - Bird Fighting Chronicles

In his previous life, Lin Chen died of cold and starvation due to his kindness being betrayed by his neighbors. Reborn, he activates the "All Things Fusion System," which allows him to consume spiritual power or points to fuse non-living objects and create new items. With the meticulous logic of an engineer and the decisiveness of a vengeful spirit, he navigates the complexities of a traditional courtyard house, dealing with a group of people, including the "moralistic" Yi Zhonghai (who schemes to provide for the elderly) and the "temperamental" Liu Haizhong (who has a twisted family). He uses the system to fight back and survive, eventually shedding his violent tendencies and venturing into business. The story intertwines the era's imprints with the struggles of human nature, showcasing the protagonist's growth from revenge to a more principled and adaptable character, as well as the complex ecosystem of the courtyard house neighborhood.
