Urban High Martial: I Have a Blade That Can Cleave the Heavens

Ji Xun dies suddenly after staying up all night and transmigrates to Blue Star, a world where spiritual energy, technology, and Awakened professions coexist. He takes over the body of an orphan with the same name. At his awakening ceremony, he manifests the once-in-ten-thousand-years SSS-grade potential, but, of all things, his profession is the universally mocked and supposedly most useless support class, making him a laughingstock across the internet. However, the "Myriad Worlds Rental System" that came with him lets him temporarily rent abilities from countless realms, while its "one slash" mechanic lets him keep them permanently for free. When everyone laughs that a support can only hide behind their teammates, Ji Xun raises a hand and unleashes the Eighteen Dragon-Subduing Palms, then summons Susanoo with his other. To his team, he seems like a harmless healer, but behind the scenes he's an overpowered, calculating schemer who can both heal and fight. From protecting Jiangcheng to fighting the evil cult "New Heaven Sect" as it infiltrates the world, and finally facing the Abyssal demons as they tear through the barriers between planes, Ji Xun will come to understand that his awakening was no joke: it is the only key to saving the world. Seven realms, seven colors, the galaxy as an offering.
