"Reviving The Blood Clan's Ancestors" 

The blood moonlight tentacle should not be able to touch the blood tubes because, no matter what, it was just a light in essence. 

How could it be a solid thing and take something with such a body structure? 

But the blood moonlight tentacle didn't really grab the 300.000 blood tubes and just casually touched them with the tip of its tentacles. 

Then, something miraculous happened. 

The blood tubes that were touched by the blood moonlight tentacle slowly floated out of their resting place on their own, moving towards the empty space at the burial hall. 

A lot of blood tubes were stored in this hall and it wasn't possible to just keep them all in one altar, no matter how big the altar was. 

Thus, there were four altars on each side of the Hall, and at the center was a magic circle that Lyod and Caroline used to create when they wanted to revive people.
