"Mr. Knight, you might want to check and see if there is any crystallization phenomenon inside them."
Fang Hong followed the suggestion, used a dagger to cut open a branch, and indeed found crystallization inside. He placed the red powder in his palm, realizing it was crystal dust, essentially no different from those magic crystals.
Luo Yu's later magic guided reactor malfunction further confirmed this point.
During an casual inspection of his magic guided reactor, Luo Yu noticed the pressure gauge had risen. Although the differences between the two readings were subtle, it caught Fang Hong's attention.
After a thorough check, he discovered that it wasn't an issue with the pressure gauge but rather the ambient magic concentration affecting the reactor's reading. The magic concentration in the Blood Thistle Woods was noticeably higher than outside. Furthermore, after his tests, he noticed that the closer one gets to Aimumu Fortress, the more pronounced this phenomenon becomes.
