Answer 1

If the male protagonist did not have the ability to inherit the recognition of the first War God and inherit his divine power through hard work, then this story might not make sense. Usually, after the male protagonist inherited the divine power, he would go through some hard work and challenges before he could truly display his strength. If the male protagonist did not work hard to inherit the recognition of the first War God, then he might not be able to truly inherit the divine power, which might cause the entire story to become unreasonable.
