The landmines had been buried for a relatively short time, certainly installed several decades after the Dead Sea Wreck had formed.
But who could it have been at that time?
The previous Ark Chosen Ones who challenged the Dead Sea Wreck?
But they were all Spiritual Ability Users with either the Fifth Sense or Sixth Sense, and there should be no need for them to use landmines.
Or perhaps, they wanted to use the landmines to divert the enemy's attention?
Or was it that, among the ships captured by the Dead Sea Wreck, there were still survivors?
Did they resist the flesh mutations in this dangerous area? Were landmines one of their methods?
As for Scavengers, Li Yelai dismissed the possibility. Located in the deep sea, the Dead Sea Wreck was unknown even to the authorities; Scavengers would not have the capability to come here.
"Jing Lin, do you have the ability to track traces?" Li Yelai asked in a low voice.
