Backing Up Her Sister

Nan Yan clicked on a post because of a particular name.

It was a post offering a substantial reward for T-1 drug.

This drug was the predecessor to the T-2 drug she had developed.

While it wasn't as potent as T-2, it was still an incredibly valuable drug.

The T-1 drug she had created in the past had been sold for exorbitant prices on the black market.

A single vial of the drug started at a minimum of one million.

Despite the high price, it was still in high demand.

Three vials of T-1 drug had once been auctioned, with the highest one selling for seven million US dollars.

Nan Yan's expression became serious.

Whether it was T-1 or T-2, only she had the real formula.

This was perhaps the only area where she was possessive—Xi Shijin had reversed the order of ingredients in her formula.

With that formula, Xi Shijin couldn't possibly produce a genuine drug, no matter how many attempts they made.
