Did I Do Something Wrong by Digging a Pit in a Mass Grave? [Book Transmigration]

Yan Ruyu, the most beautiful person under heaven, is widely known as a pretty fool. Beautiful, yes, but completely useless. Yan Ruyu looked at his delicate, frail body and decided, after much thought, that the reputation was well deserved. Especially since he was a coward who had transmigrated into a book. What's more, he had transmigrated into the story decades before its protagonist, who was even more villainous than the villain, was born. As long as he stayed alive, being a coward wouldn't matter! One day, he woke from a dream to find the world transformed, shrouded in mist. He stood up, and with every step, came across another grave. Yan Ruyu's face paled. Wasn't this a mass burial ground? He stumbled, and his frail body crashed to the ground, smearing blood across a blank gravestone. A flash of blood-red light passed, and several characters appeared on the stone. It clearly read: "Tomb of Gongsun Chen!" Yan Ruyu fell silent for a long time before digging some long-buried memories out of his abandoned brain. This Gongsun Chen was probably, possibly, maybe, most likely the protagonist of the book?! How the heck did I end up dead here? * [Historical records] Yan Ruyu was born in the twenty-third year of Tianle and died in a sacrificial formation at the age of fifteen. Gongsun Chen expressionlessly closed the file. How could a stupid fool who'd died sixty years ago keep appearing in his dreams? And in every dream, he was already dead and buried, with weeds growing over his grave! * If you're interested in the upcoming novel next door, Everyone I Used to Know Became a Big Shot, please add it to your collection. Thank you! Pei Yi woke up two hundred years later and found himself lying in a thin coffin. When he crawled out of the tomb, he finally realized how much the world had changed. The little brother who used to cling to his leg had become an elder of the Qingfeng Sword Sect. The little beggar he'd casually saved had joined the Cangliang Sect and become its chief disciple. His old friend, who used to be arm in arm with him, was undergoing a tribulation on Xifeng Peak and was said to be on the verge of becoming an Immortal Venerable... How had everyone he used to know become a big shot? Pei Yi sipped tea as he listened to the storyteller. He thought about all the reckless young men and women he'd known back then, then looked at how respectable they all seemed now. He shook his head and sighed at how the world had changed and people's hearts were no longer what they used to be. The storyteller struck the block on the table. "We've finished talking about the immortal sects. Now, let's talk about Shen Daoyue, the bloodthirsty, mad Demon Venerable..." Pei Yi spat out his tea. Shen Daoyue?! Wasn't that guy born with a sword bone, and a once-in-a-generation genius cherished by the Yunshang Sword Sect? How had he become a Demon Venerable? Pei Yi held his teacup and fretted. It was one thing for everyone else to become big shots, but Shen Daoyue... That man was his sworn enemy. The Demon Realm. [My Lord, the tomb has been broken open.] Shen Daoyue stroked a strand of severed hair and said in a low voice, "Find him." Ten thousand demons prostrated themselves before him, awaiting the Demon Venerable's command. "Search every realm until you find him!" Theme: Strive to save the world
