Just a few days before his death, he became the only Aura user in a world of magic. 
Using his knowledge and experience, he will become an Aura user again, faster than his previous life. 
Accompanied with a shape-shifting black slime, he will make sure to protect everyone he cares about and win against the Evil God Cult.

The Only Aura User In Magic World

After cultivating for a bit in the space, I directly opened a portal to humans' world. Of course, as Victoria told me, I choose a place away from humans' settlements. It's because of the vacuum. If I opened a portal somewhere close to a city or a village, the whole village can be sucked in.

How did I enter the portal even though the power of the vacuum is quite strong? My leg is stronger than the suction force. That's all there is to it.

"…so, this is the aftermath of being sucked in into the space, huh? Horrifying," I commented after seeing so many trees, rocks, and monsters got sucked in into the space.

"But it's good as another method to fight, right? I know that you will choose to use it against the cult one day," Victoria said.
