Highlights
Chen Yundong, a security guard, unlocks a 'self-discipline system' after completing a task of 100 fist swings for a week. He is rewarded with 'Grandmaster Fighting Technique.' His next task is to resist the temptation of women for three days, promising the skill 'Calmness.' Shortly after, he is reassigned to patrol the underground garage.
Chen rescues CEO Su Li from a kidnapping attempt in the underground garage, using his newfound fighting skills. She is drugged and confused upon waking, initially doubting his intentions, but Chen's sincerity eventually wins her trust. Su Li offers Chen a job as her personal bodyguard with a significant salary increase, which he eventually accepts.
Chen quickly deduces that there's a mole within Su Li's existing bodyguard team, leading her to trust him more. During a negotiation with Jiang Wenlong, who previously kidnapped Su Li, it's revealed that Zhao Shan is the mole. Jiang Wenlong introduces Miaoyin, a master of psychic attacks via zither music, which Chen's 'Calmness' skill surprisingly counters, leaving Miaoyin defeated and forced to play a 'conquering song.'
Chen receives a new self-discipline task: invite an opposite-sex person to practice yoga twice for double physical fitness. He convinces Su Li to join him, leading to some awkward but successful sessions, inadvertently completing the task and boosting his physical strength. Later, the company's network is attacked by the world-renowned hacker, Shadow, hired by Zhang Shaojie. Chen, through another system reward, gains top-notch hacking skills and successfully defends the system, even counter-hacking Shadow and stealing Zhang Shaojie's data.
Chen is appointed head of the company's security department. He receives a new self-discipline mission: practice boxing on the rooftop for a week to earn 'Grand Master Fighting Technique.' During his training, Jiang Wenlong issues a challenge on behalf of the Jiangcheng Martial Arts League and Mr. Cui. Chen accepts, despite Su Li's concerns. In a series of impressive displays, Chen defeats three martial arts masters, including Master Liu (horizontal training), Master Zhang (lightness kung fu), and Master Wang (Tai Chi), even defeating the Grandmaster Cui in an internal strength chess match. He wins the respect of the martial arts community, especially Grandmaster Cui, who recognizes Chen's talent.
Chen gains a 'Hearing' skill, allowing him to overhear Su Li's confession of feelings for him. Meanwhile, Zhang Shaojie orchestrates another plot, using Mr. Qian to steal Su Li's artificial intelligence technology. Chen and Su Li cleverly retrieve the stolen data, manipulating it to turn the tables on Zhang Shaojie.
Zhang Shaojie's modified AI system, now containing Chen's planted vulnerabilities, leads to numerous vehicle accidents, causing a massive scandal and his arrest. Su Li's company is saved, and she thanks Chen. Chen receives a new self-discipline task to live in seclusion for a year to cultivate immortality. He leaves a letter for Su Li, who is heartbroken by his sudden departure. Despite her anger, she eventually chases after him, confessing her love openly, putting him in a bind regarding his new mission.
