When the Demon Spirit Mountain King heard Su Qianqian's words, he was actually enraged.
After all, the fact that Su Qianqian had brought the demons from the Demon Immortal Dao Sect and barged into the West Heaven Spirit Temple failed to infuriate the Demon Spirit Mountain King.
Clearly, the Demon Spirit Mountain King did not take the demons of the Demon Immortal Dao seriously at all.
Perhaps it was because the Demon Spirit Mountain King knew that they could not cause any trouble in the Western Demon Realm.
Only Su Qianqian was a threat to him.
The reason why the Demon Spirit Mountain King told Su Qianqian to kneel was to make Su Qianqian submit to him.
However, not only did Su Qianqian not do that, she even publicly called him a Centipede Spirit!
This was the reason why the Demon Spirit Mountain King was angry.
