Before Doomsday, My Wife Bound Herself to a Supply Rebate System

They say a man's knees hold gold.

When Ji Xiu met the future Empress, Liu Yuyan, on the eve of the apocalypse, he knew it was time to cash in that gold.

System: [You are the System's master. The Host can only be the Host. Our permissions are different.]

[Master, are you sure you want to begin the System's initial setup?]

Ji Xiu: “Begin.”

“Confirming System Host: Liu Yuyan.”

“Set the target she can bind to and invest in as unique. The System has found the only person who meets the criteria: me, Ji Xiu.”

“Can power be returned too?”

[Master, power can only be returned to you at double the Host's strength.]

“Good. I'm still used to being on top.”

The apocalypse was about to begin.

From then on, all the resources and money Liu Yuyan spent on Ji Xiu would be returned to her a hundredfold or even a thousandfold.

But when it came to strength and cultivation, he would receive double what she had.

Ji Xiu: “System, you're truly my perfect sugar-baby assistant.”
