Mo Shu's twins in his belly, as they would say in their world, were twin Spiritual Embryos.
Spiritual Embryos were already very rare, and twin Spiritual Embryos, even in their world, were incredibly scarce.
If not for those with high status and authority, who always looked forward to the birth of such infants, and bestowed blessings and much Spiritual Power, it would be impossible to conceive a Spiritual Embryo.
Thus, the parents who usually conceived such embryos were extraordinary in their cultivation, and no one would dare to provoke them.
Sao Zha first realized that Mo Shu's children were extraordinary when she was unconscious.
Soon after Mo Shu had requested to save the twins, a qualitative change occurred in the infants.
Initially, he too was shocked, but then he was secretly relieved, thankful that it wasn't happening in the otherworld.
Otherwise, with his abilities, he truly wouldn't have been able to protect Mo Shu, and those two much-sought-after infants.
