Stop Chasing Me, I'm a System, Not Your Wife

Xiyue was an ordinary System employee at an interstellar interdimensional travel company, responsible for issuing and reviewing all kinds of transmigration assignments (yes, those various Systems you have in mind). Later, the company's technology made great strides, and it discovered how interdimensional transportation worked. But during a research trial, Xiyue was transmigrated to the world of her Host, Yan Ziwei. Since the equipment she carried could only communicate over short distances, she had no choice but to get close to Yan Ziwei. To meet the company's performance targets, she risked being discovered, but in the end, she was found out anyway...

Xiyue thought everything would be fine once she teleported back. But what do you mean the two worlds have merged?
