My Granddaughter Wept at the Wrong Grave on Tomb-Sweeping Day, So I Climbed Out to Correct Her

Jiang Yuan was born into a parallel world and lived to the age of seventy. He had no golden finger, no extraordinary encounters, and simply lived an ordinary life from beginning to end. But who could have guessed... that after being laid to rest in the earth, he would awaken the [Long Sleep System]? As long as he slept, he could grow infinitely stronger! And so Jiang Yuan began a long slumber underground. Time flew by, and the years passed. His strength skyrocketed while he slept, and before he knew it, he had reached a terrifying level no one could hope to attain. There are 365 days in a year. Jiang Yuan only wakes for a few minutes on Tomb-Sweeping Day, opening his eyes to see how his descendants are doing. This year, a fine drizzle fell on Tomb-Sweeping Day. His granddaughter, Jiang Yingxue, carried offerings up the mountain. But as she walked along... she stopped in front of the neighboring tombstone! She lit incense, kowtowed, and burned paper money. The whole ritual was for someone else's grave! Underground, Jiang Yuan watched it all, so furious that even the lid of his coffin couldn't hold him down! Paper money fluttered through the air, and incense smoke curled upward. Just as Jiang Yingxue bowed her head to light the incense, a deafening boom shook the earth, sending dirt flying everywhere! A huge hand flung open the coffin lid, and Jiang Yuan suddenly thrust himself out of the ground, pointing at his terrified granddaughter and cursing: “Stop burning that! Whose grave are you visiting?!” “Look carefully! I'm your grandpa!!” Jiang Yingxue: ???!!!
