Yu Yan came from a Mortal Beast-grade Beast World Continent, but his true strength was at the peak of the Spirit Rank.
"The last Holy War didn't have a rule that said Spirit Ranks with offspring couldn't participate. All Spirit Ranks were eligible. The female I followed roped in all the Spirit Ranks of the entire continent into the Holy War.
I was forced to take my brother's place. My brother was only at Earth Rank, not Spirit Rank. That female seduced my brother, gave birth to four sons for him, and offered the condition that I fight in his stead."
"If there were no restrictions, why didn't she have children with you?" Zi Qi asked.
Yu Yan glanced at Sally.
Sally said, "She probably couldn't. The Offspring System can't cross ranks. At that time, she was still a Mortal Beast-grade system, only able to bear children up to Heaven Rank."
Zi Qi touched Sally's round head, "So what you said was true."
