บท 289: The Forbidden Spell Explodes Forth

Before we had even flown a kilometer away, there came a loud rumbling sound that reverberated from behind us. ‘Hong! Hong! Hong!’ A absolutely violent power surged from our backs. There wasn’t any possibility to resist against it so we were pushed forward three times our initial speed by the shockwave. I didn’t dare resist against it, but instead cast a boundary to enclose everyone within to freely move along with the force in moving forward. The impact of the power was too strong. The boundary that I cast constantly vibrated, making me to spit a mouthful of blood. It was only when we were reaching the Ström Fortress that the power behind us weaken.

I stopped my movement and turned back to have a look. The sight before me momentarily made me stupefied.
