Devouring Lord

No one knew where they came from. They only remembered that day when the sky was torn apart and countless alien beasts descended from the sky and wreaked havoc among the cities, catching humans off guard. Human technological weapons even had zero damage to the alien beasts. It only took ten days. After ten days, the alien beasts disappeared, leaving only dilapidated cities, corpses everywhere, strange portals that appeared all over the world, and a thirty-day countdown. People know that this horrible thing is not over yet... (PS: Newbies write books, and they only write when they find time when they are busy. It's really cool to hit something you want to read. You can choose to save it. Maybe you will open the bookshelf a few years later and find that, eh, this book... He hasn't finished it yet. In addition, if there is anything unreasonable, you can leave a message and it will be corrected. )
