He wasn't merely thinking of using the barrier he created to block the invasion of those strange insects or other things. He had also considered invasions from other worlds!
But would this really work against spatial teleportation that could directly pass through the spaces and positions of two different worlds?
For a moment, Fei Mi hesitated as well.
She had no idea how such a situation should be handled, much less whether the barrier Shen Yi wanted to create could achieve the same effect.
Because if it could, the effort Shen Yi would save would not be limited to a day or two. That thing would be a one-and-done solution!
"If it were really that easy to cross over, our Elf race wouldn't have been left there waiting to die for so long."
Xilos let out a somewhat resentful sigh, looking thoroughly miserable.
She prided herself on being a rare genius in the Shadow World, perhaps even one that appeared only once in several centuries. Yet ever since meeting Shen Yi, she had realized that whether in age or strength, he surpassed her by far.
And after coming to Blue Star, that fact had become increasingly obvious.
Blue Star was a planet whose level and power were far below those of other worlds. Though its area was much larger than the Shadow World's, even the pinnacle of Blue Star's technology, multiplied tenfold, could never compare to the Shadow World. Not to mention that many powerful old monsters were hidden within the Twilight Abyss.
Yet despite that, Shen Yi, this freak, had appeared.
It was clearly a barren land, without even much spiritual energy suitable for cultivation or any heavenly treasures. Yet somehow, this world had produced Shen Yi, and his strength had reached a level she found impossible to comprehend.
