In the rapidly rotating gears of Shenzhen, Lu Zhe bet all his wealth on the new generation of smart home core chip "Linghe No. 1". At a time when research and development is in urgent need, the largest competitor "Huayao Technology" suspects that it has accurately copied its core algorithm architecture. When Shen Wei, Party A's representative and Party B's partner with whom they had been together three years ago, stepped over the plan he had poured so much effort into with cold high heels, the sour smell of instant noodles soaking in the rental house in the urban village, the sad penetrating power of Lin Xiu's out-of-tune guitar across the wall, and the bad logistics news were intertwined. The moment 300,000 original chips were exposed to the downpour, this war originating from the commercial battlefield and complex emotions officially broke out. The old saying "Shenzhen doesn't believe in tears" has turned into a cold sharp knife piercing the chest today. Lu Zhe stepped barefoot through the water in the urban village, and the neon billboards stung his eyes - in the reinforced concrete jungle, the last counterattack horn of the deep drifters was being blown by the determination to pierce the rain curtain.
