The thought of this sent shivers down Alex's spine. As someone who aimed to betray the Briggs family and form a new family, if something like this should happen only death awaits him. Thinking about it, he was stunned by the power of the gold tier combat techniques and wondered about the origin of these martial techniques strong enough to suppress the genes of a person. He knew little about the origin of the demon-kin secret art but he knew that any power that can make a man a superhuman just from practicing it is not normal. It's so strong that the offspring of all those who practiced it is born with the defensive genes only capable of practicing that secret technique.
This is the power only a gold-tier martial technique can have.
