The Heavenly Gate Altar, from an outside view, appeared to be a nine-layer tower, but as Yusuf Zuck stepped through the door crack, he discovered that the inside of this altar was, in fact, a separate space.
He obviously squeezed in through the doorway, but once inside the space, he began to fall from great heights. Looking into the distance, all he could see was yellow sand, and he could hear the whistling wind by his ears, with sand grains hitting his face painfully hard.
The visibility here was very low, and the sense of direction was unclear because there was no sunlight or magnetic field, so Yusuf Zuck did not know what kind of wind was blowing.
However, it was clear that the fierce winds here were enough to blow and kill an ordinary Nirvana Realm. If Dominick Sheppard came in, he probably wouldn't last long before being blown to death.
Here, even Yusuf Zuck, at the Eternal Life Ninth Layer, felt pain and discomfort, so the outcome for a Nirvana Realm would be dire.
