Su Xing rubbed his temple, absorbing the memories in his mind.
Blood Demon Sect... or rather, the entire Blood Demon Realm, had a crude and brutal method for producing low-rank cultivators!
Within the entire Blood Demon Realm, there were not only cultivators.
There were also many cities and ordinary people.
Moreover, the number of ordinary people was exceedingly large, with a population exceeding tens of billions in a single realm!
Subsequently, the Blood Demon Realm massively encouraged reproduction.
Every year, children who turned ten had to undergo a... battle of the immortal path!
The so-called battle of the immortal path was actually about letting those ten-year-olds start practicing the Blood Immortal Scripture.
After cultivating for a year, a thousand children would enter an enclosed environment.
Eventually... through slaughter!
The one surviving child would become a Qi Cultivation cultivator... and could absorb the blood sacrifices obtained from the slaughter.
