Sickly Little Sizi Knocked on My Door, and I Became a God to All Dynasties

After finishing a grueling night shift, Lin Xuan went home and found a girl in ancient clothing burning with a high fever on his sofa. Acting on instinct, he gave her modern first aid. What he didn't know was that enormous holographic sky screens had suddenly appeared above every dynasty, livestreaming his living room to the entire ancient world!

He then opened a space-time portal and frantically sent box after box of gold and top-grade Hetian jade to the modern world as child support!
