Unlimited Blade Works from the Start: Exposed by Bai Yuekui?

[Not purely romance, with interactions among multiple female characters] The protagonist, Shen Moqing, is a college student. While watching the second season of Ling Cage, he thinks Mark is useless for letting Mai Duo, the girl he likes, become Meat Soil. In a moment of bravado, he says he’d do a better job himself. To his surprise, the heavens really do transport him to the world of Ling Cage. As a frail college student, he nearly gets killed by a Spine Gu right at the start. Luckily, with the help of a System, he obtains Unlimited Blade Works from Fate. He gradually becomes the strongest person in this world, saves Ran Bing and Mai Duo, and makes Charles, 4068, and the other people who have done wrong face the consequences they deserve. He also gently persuades the Lighthouse to surrender unconditionally to Dragonbone Village so they can fight the Mana Ecology together. Shen Moqing: “You mongrel, Charles! Get off the City Lord’s seat. You’re not fit for it! What, you refuse? Then take it up with my countless Noble Phantasms!”
