THIS IS A TRANSLATION!!!
I KNOW THIS NOVEL HAS BEEN TRANSLATED BY OTHERS BUT I WILL ALSO BE EDITING EVERY CHAPTER AND WILL TRY TO MAKE IT MORE INTERESTING

HERE IS THE ORIGIONAL SYPNOSIS:

Good news, traveling to Teyvat has become the heavenly principle.

Bad news, the world of Teyvat doesn't have much time left to live.

Good news, we have a system to annex the two-dimensional world.

Lucifer looked at the countless familiar worlds with sad tears streaming down his face, and announced on the spot.

"I am not only the Heavenly principle of Teyvat but also the Heavenly principle of countless worlds."

"So, my rules are rules."
