An Academy Life: 9
/*unedited*/
A life force and aura fluctuation detector is was what Shin Jiao has in mind. He wanted to create a machine that would enable them to detect and differentiate between beast-men and humans. This way, even those with a high level of concealment can be detected.
As a spy, he knows how dangerous he is when it comes to a city or a civilization's security. Spies can infiltrate and even become leaders of a country and it would be too late before anyone can know it. And Shin Jiao didn't want that to happen since his new family lived in the city.
If the city would fall then his family would also be affected and be caught in the destruction. This is the thing that Shin Jiao didn't want to happen the most and one of the reasons why he wanted to share this technology.
