Boom...!
But just as before, the military formation's collision still failed to break through the fourth level of the barrier.
Rumble...
Instead, it met a backlash from the power of thunder atop the barrier, forcing that military formation to retreat another several hundred zhang.
Seeing this, the veteran general Jiang Yu, standing beside Gu Huai, let out a long breath and said:
"The Nine Abysses won't find it so easy to break our Heavenly Thunder City's barrier."
By now, all thirty-odd veteran generals had arrived atop the city wall.
They were all ready to descend from the walls and meet the enemy at any moment.
Rumble...!
But before their relief could last long, another demonic army charged out of the billowing yellow sand behind the first.
Boom...!
Under their astonished gazes, the two demonic armies merged into one, and in the hands of another demonic general, their battle intent fused into an enormous spear shadow.
Before anyone could recover, that demonic general hoisted the enormous spear shadow and hurled it at the fourth level of the barrier ahead.
Bang-!
Amid a deafening collision, the enormous black spear shadow actually pierced straight through Heavenly Thunder City's fourth barrier.
Boom...!!
Then, under the torrent-like charge of three thousand demon-armored troops, the fourth barrier shattered with a crash.
Rumble...
More terrifying still, after breaking through the fourth barrier, the merged force of three thousand demon-armored troops began charging even more fiercely.
Boom...!
As they neared the fifth barrier, the demonic general Shanxiao and the other demonic general each held a demonic spear formed from battle intent.
Boom...!
The next instant, the two demonic generals hurled their enormous spear shadows together.
Bang...!
Though the spear shadows did not pierce the fifth barrier this time, fine cracks had already spread all over it.
Bang-!
