Wallace, who had been busy with his master after getting involved with the Celestial Being, was now spending his time in one of the floating islands where Aeolia was staying at.
The floating island was unlike the others as it has a special laboratory where Aeolia specifically made to conduct his study for the seventh generation mana artifacts.
The young man had already seen them before as Aeolia had introduced it to him and his master when they first met at the deepest floor of the Z-Tower. He showed them bottles of dark liquid and was introduced as 7th Gen by Aeolia.
A liquid can also be a mana artifact? It was a question that came to their minds after seeing it the first time.
But even though they were surprised to learn about it at that time, he remembers the person's identity. This made them calm down and admire his creation instead.
