Before he knew it, a month had passed.
The demon-slaying cannons of the monster-eating city had stopped firing recently because the heaven and earth energy in the illusion had been used up.
As a result, the enemy was unable to absorb the world Energy, which led to a slow decline in strength.
Although the energy of heaven and earth could be replenished, the area outside of the demon-eating city was very special. Because of the bombardment of the demon-slaughtering cannons, it had become almost a vacuum.
Even if it was replenished, it would be consumed in a very short time, and then a vicious cycle would continue.
Unless the heaven and earth energy exploded and formed a scene similar to a tide, it was impossible for the heaven and earth energy to recover to its original density before these enemies were all dead.
Without earth and heaven energy, the cannonballs couldn't ignite the flames, and they couldn't cause a large scale damage to the enemies.
