When he returned to his universe, Xu Jingming looked at the high-dimensional door.
I was smacked flying by the cosmic spirit in the auxiliary universe's starting area on my first visit! Xu Jingming smiled. He didn't feel embarrassed; instead, he was very excited!
The stronger the cosmic spirit, the richer the auxiliary universe's heritage. Weak auxiliary universes couldn't produce powerful cosmic spirits.
The probability of others discovering this auxiliary universe is negligible. After all, it wasn't found for so long. Even if someone discovers it, nobody below a high-dimensional lifeform can destroy the high-dimensional door. Xu Jingming was still very at ease. This was also the reason why he spent a lot of money setting up the high-dimensional door.
Once it was set up, it was his.
