My Grandpa Really Is an Emperor

Betrayed and beaten into a coma, the hero heard his grandfather's voice, dug up a treasure box, and connected with his grandfather who had traveled back to ancient times. Thinking his grandfather lived in hardship, he burned hell money, which became real silver in the past. His rebel-leading grandfather sent back a magical pill, giving him superhuman strength. He then met a noble daughter. To propose, he burned more paper and received a grand betrothal gift. On the wedding day, he produced the lost imperial jade seal. When everyone thought it a fake, his fiancée stepped up and proposed to him instead.
