The powerful being that was blocking their way did not have a body like most living beings. It was in a state of colourful gas that was constantly changing its colours. But when this being initiate an attack, it could make its body solid and very hard.
As for this being's powers, from what Rein had observed, it was unable to use any kinds of long distance attack. But it was very compatible with the space of the void, so this being was capable of moving very fast, almost instantly in this void. So the lack of long distance attack was not even a problem for it.
As for how this entity attacks, it did nothing special and just attacked in a straightforward way.
But that simple straightforward attack was able to split the solid and compact space of the void like a knife through butter. Its attacks were extremely fast and dodging them was almost impossible. So Rein would be trying to keep this monster as far away from him and his lovers as possible.
But there was one thing that they needed to be careful about. Even though this monster did not have a long distance attack, sometimes it would suddenly start to randomly expand its gaseous body. If anyone came in contact with the expanding gas, then that person would immediately be attacked with this being's full force.
Avoiding that would be the most important thing as this expansion happened randomly and the pace was also very fast.
So Rein would be covering his lovers with his space manipulation technique and would try to stay away from the powerful being as much as possible. He had investigated this monster very thoroughly and had also managed to find out some patterns in its movements. He was going to use those patterns to plan his route.
The space around the monster was always under its control as their compatibility was so high. So if this monster came close to Rien's location, he would not be able to hide everyone's presence anymore.
As soon as the process of breaking the space started, there was a violent fluctuation in the void. The powerful entity immediately noticed this fluctuation and saw through the barrier that Rein was using to hide their presence.
When this monster was still unaware of their presence, Rein's barrier was able to hide it. But as soon as this entity tried even a little bit to see through the barrier, it was able to do that immediately.
Rein dispelled the barrier as it was useless now and went toward this entity. He wanted their fight location to be as far away from his lovers as possible. Rein was still worried if this entity would follow him or not as it might also target his lovers. In that case he would not be able to prevent this being from disturbing Colinde and Lan.
But fortunately this entity judged Rein to be the most dangerous person present here and went after him. Rein did not fight this being head in and instead used his Spatial manipulation to avoid its attacks.
Not only that but Rein also used his eye of Truth to find weak points of this being and attacked them. Those attacks did not do too much damage but it was at least able to stagger the entity and that bought more time for the ladies.
Rein was obviously not able to dodge all the attacks and was badly injured. But with his perfect body's regeneration and his own willpower, he was somehow able to hold on. But his situation was not looking good and if this continued Rein would definitely die even with his overpowered self healing.
After a few moments, Rein suddenly felt the presence of the world very clearly. This was the sign that Colinde and Lan were able to successfully open a portal. Now Rein just needed to somehow reach the portal while holding this monster back.
That looked like an impossible job but as this being moved using the space as a medium, Rein used his space manipulation beyond his limit to block the perception of space for this being. Then he used this slight chance to go toward the portal.
Just a moment before this portal closed, Rein was able to pass through it and was able to escape the void. That was definitely a close escape.
