Yang Xiao's skills were indeed formidable. Not only had he once penetrated the Zhang Family's defenses alone, but he also managed to leave them half-dead without breaking a sweat.
At that time, the Zhang Family's masters were not at home, and he had gone alone to find Chen Yufei, so Yang Xiao's true strength was never fully revealed. Despite that, the fact that Yang Xiao was not weak was undeniable.
After all, during that visit to the Zhang Family, although their masters were not present, there were still many bodyguards protecting the family.
The strength of those Zhang Family bodyguards was not to be underestimated, yet Yang Xiao was able to defeat them single-handedly, which speaks volumes about his powerful abilities.
Therefore, Zhang Yang did indeed have some apprehension about Yang Xiao.
The unknown often invoked fear in people.
To Zhang Yang, Yang Xiao's strength was an unknown factor.
That's why Zhang Yang took Yang Xiao's warnings to heart.
