Threshold

In 2069, mankind's wild imagination of the future has been basically realized. However, a small number of wealthy people are not satisfied with the current status quo. They do not hesitate to spend a lot of money to invest in a cutting-edge scientific team, just to develop life reagents that can make life longer. After ten years of sharpening the sword, these people's desire to pursue eternal life was realized by a team from the Principality of Gilan, headed by Professor Liu Shaoxuan, who developed the HP-19 reagent. Just one tube of reagent can maintain the body's optimal condition for three months.
