Immortality Begins When I Refuse to Be the Protagonist

Other people transmigrate with a System, dominate the world with boundless arrogance, wield a powerful golden finger, level up and slap faces all the way, and have beautiful women fall into their arms. Lin Gou transmigrated with a System too... but the System crashed! Not only that, it keeps glitching out and assigning bizarre quests, deducting Harmony Points, and even labeling him “extremely dangerous” and recommending that he be “formatted”! To make matters worse, his cultivation technique is messed up too! At the Qi Refining stage, it already attracts terrifying stellar energy. Its fluctuations are abnormal, and at any moment he could be detected by the cultivation world's “antivirus software,” namely the sect's higher-ups and powerful beings, then captured and dissected for research! Trapped at the bottom of the ruthless Xuanxi Sect, with rock-bottom aptitude, a life-threatening cultivation technique, and a System that keeps failing him, what is his only way to survive? Keep his head down! Be more low-key than anyone, better at hiding than anyone, avoid every danger, and live like a mouse... No, live like the cultivation world's ultimate “invisible bug”! Yet this broken System and abnormal cultivation technique unexpectedly grant him **“Bug Compatibility”**. Traditional detection methods don't work on him, energy markers left by powerful beings are completely useless, and even the System's occasional garbled messages might conceal deadly intelligence or “program exploits”! So, while appearing to be a diligent menial disciple of the sect, he secretly “data mines” the sect's garbage dump. The discarded scraps and ancient fragments there turn out to contain “base code” and “unconventional patches” capable of helping him break through bottlenecks!
