Laws were invisible and untouchable, but sometimes they could be felt. It was just like how Zhao Hai's strength had increased. Whether it was on the ark continent or the Protoss, he couldn't stay there because the laws were rejecting him. He couldn't see or touch the laws, but he could feel the laws rejecting him. This was the power of the laws.
Before Zhao Hai became an expert in the longevity stage, liquid silver was rejected in the leaping Dragon World. This was also the power of the law. Every world had the power of the law. Once one's strength exceeded the power of the law, the power of the law would naturally reject one.
However, Zhao Hai had never thought that the power of a law could actually strengthen everything in an interface. It was clear how powerful the power of a law was.
