Gu Qing Shan walked up to the second Fiend King.
He crouched down, looked at him and said: "Tell me how you're going to return"
The Fiend King smirked: 『 I can bring you back with me 』
"No need" Gu Qing Shan looked at the rest of the evil creatures: "I still haven't decided which one of you I'll visit"
As the Fiend King saw him raising his sword, he hurriedly replied: 『 In total darkness, use your fingers as a source of light and your voice as a guide, you need to say a total of 39 incantation mantras 』
He then recited a long series of incantations.
Gu Qing Shan carefully listened and memorized it.
As the Fiend King finished reciting, he slowly disappeared in front of Gu Qing Shan.
He had returned.
Gu Qing Shan came for the next Devil King.
That Devil King's eyes turned a bit before speaking: 「 Recite the following incantation 」
Gu Qing Shan immediately drew his sword and heavily slashed the Devil King.
