The group saw a vast cave with multiple passages around the cavern with numbers on top of each cave passage. There were a total of 10 cave passages and ten numbers, from 1 to 10.
"The numbers indicate the difficulty."
After Lilith finished speaking, Erix created a portal connecting to their cave.
A few other people were waiting while sitting, talking, or training in this cavern while their companions or subordinates went to challenge Tombs.
They were surprised to see Erix creating a portal and noted the group.
Afterward, Lilith and Reinala stayed at the portal while Erix, Rin, Lily, and Klelia went to the level 1 cave passage.
After entering, they saw three tombs and no people.
Lily walked ahead and said, "These are three level 1 tombs here. We have to touch one of them, and it will absorb us into the battlefield, where we'll fight a challenging individual."
