The effectiveness of the mental shockwave startled Lin Zhen.
Under the combined onslaught of Allen and Banahak, his spiritual power finally advanced, reaching the Diamond Middle Stage.
Xiao Nuan's Innate Devouring also manifested in his spiritual power. As such, Lin Zhen was essentially not afraid of any mental shock from people whose spiritual power did not exceed his own.
Those whose spiritual power does not surpass his, won't impact him at all. Mental shocks would not disturb him nor interrupt his teleportation. Instead, it would become nourishment for the advancement of his spiritual power.
However, it is not capable of being absorbed and devoured instantly - it also requires a digestion process.
Lin Zhen naturally couldn't digest the mental shocks launched by these people in an instant. He wrapped these several spiritual power with his own, and the combined forces resulted in an unprecedented giant mental shock.
