It is still possible to have one or two children, but it is absolutely extremely rare for people like Xu Huanniang to give birth to nine children in a row at the late stage of foundation establishment.

This made the Ten Thousand Poison Demon King ecstatic, and he couldn't help but roll up a demonic cloud and brought Xu Huanniang back to the Jiuying Blood Refining Sect.

After being brought back to the Jiuying Blood Refining Saint Sect, Xu Huanniang refused to obey at first, so she endured all kinds of cruel torture from the Ten Thousand Poison Demon Lord. Xu Huanniang's will was also extremely firm, even though she was tortured by the Ten Thousand Poison Demon Lord in every possible way.

, she also refused to obey, which gave the Ten Thousand Poison Demon Lord a headache.

In desperation, the Ten Thousand Poison Demon Lord began to torture Xu Huanniang's nine children. The nine children of the Nine Sons Mother Heavenly Demon Art must at least be in the foundation-building stage before they can be refined into demons.

Xu Huanniang's eldest child is only at the eighth level of Qi training, but this is not a problem at all for the Ten Thousand Poison Demon Lord.

After he imprisoned Xu Huanniang, he began to personally teach the immortal skills to nine children. The immortal skills he taught would be regarded as sacred scriptures even in some second- and third-rate immortal sects.

Moreover, he did not lack these low-level immortal cultivation resources, so under his teachings, the cultivation of several children immediately improved by leaps and bounds.

Not long after the boss reached the foundation building stage, he suddenly and inexplicably disappeared without a trace.

More than a year later, the second child also broke through to the foundation building stage, and just like the eldest child, he suddenly disappeared not long after.

This naturally aroused the suspicion and dissatisfaction of the other children, but the Ten Thousand Poison Demon Lord did explain that after breaking through and entering the foundation building stage, he would need to practice in seclusion to consolidate his realm. After all, the children were not old, so they did not have too much suspicion.

In fact, after breaking through the foundation-building period, the eldest and second eldest brother were refined by the Ten Thousand Poison Demon Lord into the Nine Son Demon.
