Muyu's expression was a little heavy. Before he met Zhao Hai, he didn't really care much about the power of faith. However, after meeting Zhao Hai, he realized the importance of the power of faith. Zhao Hai had the power of faith, and his strength was much higher than those of the same level. Zhao Hai could now fight against an immortal stage cultivator, which was something no one else could do.
Of course, Zhao Hai's strength wasn't entirely due to the power of faith. However, to Muyu, the power of faith was the most important factor. Hence, Muyu started to pay more attention to it.
Now that he heard Zhao Hai say that the people from the Tong Tian tower had used power of belief, Muyu could not help but be even more shocked. He finally understood why the people from the myriad world battlefield were no match for the people from the Tong Tian tower.
