After this mutant beast appeared, it headed straight for Xiao Zhan's location, without even sparing a glance at the defensive line, as if it knew at first sight that Xiao Zhan was the biggest threat.
Xiao Zhan frowned in realization; the mutant beast's target was him, disrupting his plans.
He had no choice but to give up.
But just as he was about to make a move, the voice of Ghost Abacus suddenly rang out.
"Try my newly improved Seventh Grade Crystal Core Energy Cannon!"
On the defensive line's wall, a turret as large as a small villa extended a cannon barrel, ten meters long with a fifty-centimeter caliber, aiming at the Seventh Grade mutant beast charging towards Xiao Zhan!
Ghost Abacus inserted a crystal core of a Seventh Grade mutant beast into the drive core.
As his finger pressed a button switch, suddenly, a low hum of energy absorption sounded within the turret.
Following that, a mass of red energy gathered at the nozzle of the barrel.
