After casually slaying that Spirit Race Earth Immortal, Lin Baichuan immediately returned to the passage entrance.
Since someone already knew about this place, more people would inevitably find out.
He did not believe that only this Alien Races squad knew of Langya Blessed Land. He could not afford such wishful thinking.
"We must develop Langya Blessed Land as quickly as possible and obtain all its resources..."
Lin Baichuan murmured to himself.
With a thought, an array disk the size of a millstone flew out and fell into the pool, transforming into a grand array that radiated terrifying killing intent and sealed off the entire passage entrance.
This was an immortal array.
Though it was only first grade, it was a genuine immortal array, its might far exceeding that of any spirit array.
Since he knew others would come, Lin Baichuan naturally would not sit around and wait for death. He had to make preparations.
This killing array was merely one part of them.
After setting up the grand array, Lin Baichuan moved with a thought and plunged into the passage.
The stars shifted and the world turned.
The next moment, Lin Baichuan arrived within Langya Blessed Land once more.
Then, with another thought, three more array disks flew out, forming an even more terrifying killing array as they descended upon the passage entrance.
This was the second layer of assurance.
With two layers of killing arrays in place, even if someone truly found this place and broke through the first killing array, the moment they dared step into the passage, they would surely suffer the attack of the second.
This killing array had reached the peak of a first-grade immortal array. Its power was enough to effortlessly kill any Earth Immortal.
Even a Heavenly Immortal expert could very well perish
