I Swallowed the Whole Abyss

If someone else travels through the system, I will be transported directly to an abyss of sin where countless demons are imprisoned? Whatever is lacking, it is up to oneself to devour it. Don't know the exercises? It doesn't matter, the skills of thousands of monsters can be swallowed up at will. Weak? There are all kinds of constitutions including metal, wood, water, fire and earth. Not satisfied? What about the chaotic body of gods and demons? Lack of equipment? Do you want to use the teeth of the Abyss Spiritual Dragon to make a sword, or do you want to use the scales of the Heavenly Void Holy Dragon to make armor? Unstable foundation? Small things, there are countless ancient artifacts here to help you upgrade stably. Is it too much trouble to swallow them one by one? As long as you have the ability, you can just swallow up an abyss. You said you wanted to become the Great Demon King, open the abyss and launch a doomsday war? It is still recommended that you swallow a few more Beast Emperors and Demon Emperors that can be summoned to make it more stable~
