His name is Zhang Bairen, and patience is the first thing he learned after traveling through time. Endure the boring practice, endure the cruel battles, and even more endure... The ubiquitous "rules" in this world. As an engineer, he instinctively sought the logic behind rules. In the end, he was shocked to discover that the entire universe of cultivation was actually a huge extra-dimensional system! Heavenly Tribulation is a system cleaning tool, and ascension may seem like a supreme honor, but it is actually a "data migration agreement" that cannot be refused. Once you accept it, your past, present, and even future will be uploaded to an unknown "fairy world server", and your destiny is no longer up to you. Did those ascended ancestors gain eternal life, or did they become part of the system? Fairyland, is it a paradise or a prison? Zhang Bairen was silently accumulating strength, but his hacker instinct was ready to activate. He began to spy on the frequency of the catastrophe, analyze the composition of the guiding light, and even tried to deceive the system... He wanted to find the loopholes in the "Ascension Agreement" before the next catastrophe came. Either, find a way to refuse ascension and stay in the world; or, hack the system and rewrite the rules! When the final thunderstorm illuminated the world and opened the passage to the immortal world, Zhang Bairen raised his head. What flowed in his eyes was no longer aura, but an endless stream of data. "Protocol analysis completed. Tiandao OS, I found your vulnerability."
