Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

He died in an accident and was reincarnated into another world. The Gundam works he had read before his death and the techniques in various military novels could be brought to another world.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?

Li Wei lived a dull, overworked life—until destiny (or a rogue truck) intervened, catapulting him into a world of mystical cultivators and deadly power struggles. Waking up in the body of Li Wei, the infamous and lazy heir of the Immortal Ice Sect, he finds himself in a precarious position: surrounded by enemies, burdened by a reputation for arrogance, and targeted for assassination. The only thing worse than inheriting this life? Realizing his new body’s cultivation potential is off the charts... if only the previous owner hadn’t been an idle narcissist.With the sect matriarch as his coldly disappointed mother, a stoic yet dangerously competent protector in the ice-cold beauty Leng Yue, and a mysterious “Young Master System” pushing him toward reckless behavior, Li Wei must balance survival with ambition. Every quest forces him to embrace the absurdities of an over-the-top cultivation world—whether humiliating enemies or accumulating riches—while concealing his true identity as a transmigrator.But as he’s exiled from the safety of his sect and thrown into the chaotic world below, Li Wei quickly learns that charisma, cunning, and a knack for manipulation might be even deadlier than swordsmanship. After all, why fight fair when you can command, deceive, and dominate?With ancient relics, feuding clans, and dangerous beauties complicating his journey, Li Wei's rise through the cultivation ranks is anything but conventional. What starts as a quest for survival may just become a path to unstoppable power... assuming his outrageous system quests don’t get him killed first.Will Li Wei overcome his past’s shameful legacy, outsmart his enemies, and become the true master of his destiny—or will his laziness, scheming rivals, and shameless arrogance bring him to ruin?
