Struggling barbecue shop owner Chen Kao was planning to close down when two old banyan trees at his shop entrance unexpectedly connected to the ancient world. Distressed noble family young lady Su Mingyue accidentally time-traveled over and used a golden hairpin to settle the barbecue bill. Chen Kao discovered the secret of two-way shuttle, where modern snacks and groceries could be exchanged for gold, silver, and antiques. While using the night market to disguise the two-realm passage and conducting cross-time-and-space business, he also helped the Su family resolve their crisis.
