His corpse burned in the flames, turning into black ashes and dust that sank towards the ground, and before it touched the ground, it was encased in ice, turning into crystalline ice dregs.

Captain Murphy let out a surprisingly surprised cry:
"This guy is actually protected by the Death Herald Guild's 'Soul Retreat Crystal'! He is a high-level spy of the Death Herald Guild, not ordinary intelligence personnel!"

"Grett, wait for me here, don't move. I must catch up with that spy, or our plan will be exposed. Mars, you guard here too. If I don't come back in time, take Grett to the first underground level."
"Yes, Chief Officer." Grett answered in unison.
