Grai's peculiar change in that instant was felt most clearly by his opponent, Zhao Tianlong, as his accumulated strength and exuberant fighting spirit had appeared to spontaneously collapse and disappear.
Zhao Tianlong did not know exactly what had happened. However, he was certain that it definitely had to be related to Grai's weakness his youngest had mentioned.
He had seen the expression on Zhao Zimo's face. Being all too understanding about his youngest brother, he was able to understand precisely what had happened upon seeing Wang Zhong's eyes.
Although he would have deep regrets for being unable to fight all the way to the end against Grai, being a member of the Zhao Family, he wasn't a naive little kid. To them, victory was their one and only goal. If there were anyone that he would feel hatred towards, it would be himself; he could only hate himself for being too weak.
