Because the global fertility rate continues to decline, the world's top scientists were ordered to research countermeasures. After hundreds of failures, the scientists developed the abo drug. By injecting the corresponding drug, you can become one of Enigma, Alpha, Omega, and Bate.
Enigma has the highest level, and Bate has the lowest level. Those with higher levels can impregnate those with lower levels. In other words, these medicines can make men pregnant, thereby increasing the global fertility rate, but the children born are still ordinary people.
Later, scientists invented a technology. This technology is simply to add animal genes to the original abo. Of course, the selection of animals also needs to be tested.
After a few years of this, the global population returned to normal, and the whole world was peaceful and beautiful. However, some wealthy Bates were dissatisfied with being Bates and wanted to use their children to change their class. They bribed the examiner when the child was almost 18 years old or used some hidden means to tamper with the test results. For this kind of behavior, governments in various countries secretly set up investigation teams in their own countries to solve this problem.
To put it simply, the job of the investigation team is to investigate those who tampered with the test results. If the situation is true, an assassination will be arranged. This investigation team has a codename called Thorn.
They specially selected some Enigmas and Alphas who had no living relatives but had high strength and IQ to talk to them. After asking them if they were willing, those who were willing would take a more difficult test, and those who passed would become a member of Thorn.
Then they go through ultra-intense training.
