The weapons mounted on the assault tanks are all heavy war machines, so they can't be fired instantly; they need to be charged.
However, their charging speed is very fast, and in just a dozen seconds, they were fully charged.
Once charged, their barrels flickered with dazzling flowing light, which was an almost overflowing mighty energy!
Su Yu did not immediately order them to fire but instead flew above the mechanical battle group, activating various amplification skills:
Warfire Symphony! Electromagnetic Fury! Convergence! Full Firepower! Matrix Battle Group!
In a short time, these five skills were applied to the five assault tanks.
The normal combat power of the assault tanks was already six-star peak.
With these five skills, it immediately rose a full grade, with normal combat power reaching the seven-star level!
Boom!
The assault tanks fired!
Each tank simultaneously launched three thick beams of cannon light, bombarding toward the City of Heavenly Punishment!
