The Live-In Son-in-Law of the 1960s: The He Family's Six Sisters Fight for Favor

Qin Weifeng was reading a novel when he fell asleep and woke up transmigrated to the 1960s.

His home is bare, and supplies are scarce? No problem!

By chance, Qin Weifeng awakens the Spacetime Koi System, which opens a portal connecting him to the modern era.

Ration coupons and antiques from the 1960s are priceless treasures in the modern world;

Cheap modern goods are hot commodities that everyone in the 1960s scrambles to buy.

Taking advantage of the information gap, Qin Weifeng thrives on both sides and makes a fortune.

Looking at the lovely He Jiali beside him, Qin Weifeng grins. “Stick with me, and I’ll make sure you eat well and live in comfort!”
