All three injuries were fatal injuries to many cultivators and talents below the Dao Soul Realm. But then, Zi Xiang never expected that even after estimating Xiao Ming's worth as being blessed with the thirty six meridians and a unique heavenly physique which brought him great luck and success, he still underestimated the son a divinity too much.
Against the earlier crisis, it had all happened too suddenly so he wasn't willingly able to seize the initiative and meticulously plan a means to save himself. It could be said that he was sneaked on and assassinated by Zi Xiang.
As expected, assassination flowed in the bloodline of the Zi Clan. It was a trait that appeared on both father and son.
So right now, Xiao Ming was in between a state of being safe and unsafe. He could move on with the 72 sacred meridians and the other two Xiantian cores treat today's injuries like they weren't existing in the first place.
