Technical genius Lu Ze, to repay Shen Zhaoshan's kindness, spent three years living under an alias assisting his daughter Shen Qingwan in running Qizhi Technology. After securing a major order from Xinghan, he was publicly dismissed from his position as Technical Director, forced to sign a credit transfer agreement, and had no choice but to resign in anger. As soon as Lu Ze left, the company's security system rapidly paralyzed; Chen Yu, the Silicon Valley director relied upon by Shen Qingwan, was a fraud of no real talent, even colluding with overseas hackers and nearly leaking core data. Lu Ze stepped in under the identity of Xiao, the top-ranked red hacker, repairing the system within an hour, rooting out the mole, and exposing Chen Yu's truth of impersonation and treason. Shen Qingwan was filled with remorse, while Lu Ze headed towards a brand new career, proving that crossing the river and breaking the bridge will ultimately reap its own bitter fruit.
