The Demon Spirit Mountain King had already deeply realized how terrifying Su Qianqian was.
He did not want to give Su Qianqian another 15 minutes of life.

Since that was the case, why should he take them to heart?
However, Su Qianqian was different.
The Demon Spirit Mountain King had used two consecutive sorcery techniques that could kill the Five Grand Demon Patriarchs instantly. However, they were nothing to Su Qianqian.
Moreover, Su Qianqian had easily resolved them both.
