Across the Heavens, I, Xiao Yan, Didn't Use Cheats

What if Xiao Yan had transmigrated a few years later, into an age of information explosion? What if, in his darkest hour, he gained a golden finger that could project him across myriad worlds? What if he truly acted like a proper transmigrator? When a butterfly flaps its wings, fate derails from its original track. As he strides through the heavens, unleashing his full talent, what kind of spectacle awaits? Standing before Ace, he refines the Mera Mera no Mi—stripped from him as payment—into a crimson pill in an instant. Fixing his gaze on Akainu, Xiao Yan smirks. Sorry, but he's a cultured man, and this is a story about hard work and sweat. "Buddha's Wrath Flaming Lotus!" "Teacher, have you also lost your beloved?" Xiao Yan scratches his head and hands over a thick catalog. "Actually, I do have a few ways to revive the dead. Not to mention the combination of Reanimation and Rinne Tensei..." Yao Lao stares dumbfounded at the massive tome of resurrection arts. "What's this about using grass-type magical beasts' life force for repeated sacrifices? This secret art has no cost?" "And if necessary, I can sacrifice a large number of beasts at night to revive someone, then swap them back without loss during the day?" Years later, at the gate of the Soul Realm in Zhongzhou. "I remember sending an elder to deal with things back then—what went wrong?" Staring at Xiao Yan's towering ten-thousand-zhang emperor body, Hun Tian looks up to the sky, speechless, wondering how it came to this. The Soul Hall Dou Ling who was ordered by Protector Wu to eliminate the Xiao clan—only to be one-shotted by a cheating Xiao Yan—has no comment.
