In the Year 350 of the Anping Dynasty, humans were faced with a huge crisis. Earth was invaded by monsters from another dimension. Fortunately, Su Yu awoke a power where he possessed a scripture that allowed him to contain everything in existence. With that power, he was able to face the coming apocalypse.
The armies of the heavens were only under the orders of invincibility!
As for the armies of the heavens battlefield, they only listened to the commands of the manor heads or the Great Qin King.
Before the upper echelons had completely fallen out, the military would not start a war.
It was also because of this that these tens of millions of soldiers still had their morale. They would not scatter like birds and beasts just because a few invincible soldiers had died.
