Chapter 298: That is a Mature System

The battle outside the mountainous region had ended in a short amount of time. Although brief, the battle was exceedingly brutal. Of the thousand Skeleton Flying Dragons I had, nearly a hundred had been lost.

Although the ground fortresses were few in number, their Combat Power was fundamentally strong and their firepower even more terrifying.

Even because they were thicker, my Death Energy took some time to completely penetrate them. That's why they could hold out for so long; if not for this, my losses would not have been so great.

But if I had used other combat forces, the effect would probably have been even worse.

Without Death Energy that could directly penetrate the enemy's defenses, other attack modes would definitely be slower. Even if the Undead do not fear death, the killing efficiency of technology is well recognized.

"Damn it, they died so quickly, the enemy's strength is really too strong."
