Gao Chuang told Meng Chao that the development of Gene Serum and Spirit Energy Martial Dao had its own peculiarities.
Because no two people had exactly the same constitution, entry-level mass-market goods were one thing—labor dispatch companies could find large numbers of Drug Testers in minutes.
But many powerful mid- to high-level Transcendents needed a particular Gene Serum or Spirit Energy Martial Dao technique tailored to their own circumstances.
For example, a mid- to high-level Transcendent who had once suffered some injury that damaged a certain spirit vein would need a Drug Tester with damage to the same spirit vein in order to learn how a particular advanced Gene Serum would affect him.
If some young master from one of the Nine Great Cultivation Families wanted to advance by leaps and bounds in the shortest possible time, attempting to combine seven or eight extremely overbearing Gene Serums with unapproved cultivation equipment into a comprehensive training plan, yet was unsure of the odds of suffering Cultivation Deviation—or how to treat it if it happened—
Then he would find several poor youths similar to himself in age, build, and cultivation school to serve as stand-ins and test the comprehensive training plan's effectiveness and danger first.
Sometimes, the demand came too urgently for legitimate labor dispatch companies to supply it.
At other times, clients did not want anyone to know the content or progress of their research projects.
That was when brokers from the Nine Streams of Three Religions like the "Tailless Monkey," with their extensive connections, became immensely useful.
Through the black market, Gao Chuang had gotten to know a whole crowd of rich and powerful young masters, giving him control over the demand side.
The Tailless Monkey, meanwhile, knew plenty of poor youths who lacked the money to buy scarce resources
