Chapter 47: Ch 47: Four-direction Death Swamp

Getting his hands on the secret technique, the middle-aged man immediately thought of refining the Blood Sulphurous Stone, but he didn't want to be high profile and attract the attention of other powerhouses. So, he stayed put and silently lured a few hundred people to the abyss first before killing them, extracting their blood essence and letting the soon-to-be Blood Sulphurous Stone bath in them.

After that, he again lured a few hundred people and did the same to them. He used this strategy and lured thousands of people inside the abyss and killed them. Finally, when he settled everything and knew he has to wait for a few hundred years of time, he laid down countless deadly illusion formations and even ordered the Evil Spirit, that born from the grievance and other negative emotions of people he killed, to stay here and protect the Blood Sulphurous Stone.
