"Hard to say..."
Shen Yi's brows knitted tightly, and his expression darkened.
The fundamental purpose of this trip was to protect Blue Star. If he could eliminate the threat of the Black Fog once and for all, that would naturally be the best option. However, the Boundary Stele sounded like a solution, but in reality, it was a double-edged sword whose pros and cons were hard to separate.
If the Black Fog's corrosion had happened elsewhere, that would have been one thing, but Blue Star's situation was exceptionally complicated.
Although the power of the Black Fog had been forcibly sealed by Winnie, its roots and infiltration had not been completely cleared. They might even be hidden deeper than before.
Once the Boundary Stele was used, its compulsory purification scan might not only lock onto the remaining Black Fog, but could also judge those who had been slightly affected, had not yet fully transformed, and even special existences like Wen Ke'er as sources of corrosion as well. They might be erased outright.
At that point, the people and things on Blue Star closely tied to him would probably be unable to escape. That ran completely contrary to his original intention of protecting Blue Star.
Alvin keenly sensed Shen Yi's hesitation, and the information he transmitted carried a hint of understanding.
"If the world you come from, or even the entire star region it belongs to, has long had traces of Black Fog corrosion, then I suggest you had better not use the 'Boundary Stele' lightly. The smallest scope it was designed to affect is at the level of a 'small star system.' A single planet is insignificant on the scale of the universe. To the Boundary Stele, it does not even count as a 'target.' It is more like a speck
