The Secret Technique of Conquering the Country

All the six kingdoms of Middle-earth have secret techniques, such as refining elixirs, refining weapons, or refining souls. It's just that people need to be used to refine demons. As a result, many cultivators became possessed by demons, lost their minds, and committed more killings. In order to seek peace, the six countries signed an alliance to prohibit the use of humans to refine demons. The secret technique was originally sealed, and the secret technique was deleted and optimized to eliminate risks. But originally they were all sealed in the Demon Suppression Tower, and not even the king could read them. I don't know when, a rumor appeared in various countries. If you collect the six secret secrets of the country, you can directly become a true immortal and ascend to the immortal gate. Qi Qianchou ate the candied haws and said: That's impossible. Things with that kind of power must be seven.
