Gravis felt nervous.
The highest Heaven would appear right beside him? It was one thing to meet a Heaven, but it was something entirely different when meeting someone on his father's level. This was one of the two beings at the absolute peak of the Cosmos.
Gravis waited for some seconds while nothing happened. Meanwhile, his father started looking over to the side with narrowed eyes.
Clink!
The quiet sound of a cup being moved could be heard, and Gravis saw the third cup levitating seemingly out of its own volition. Then, it angled, and the coffee that poured out of the cup vanished into nothingness.
Obviously, the highest Heaven had already arrived, and it had just taken a sip of the coffee.
Yet, Gravis was unable to see the highest Heaven. He knew that it was beside him, but it was simply invisible to him. However, the fact that it was invisible made it appear only more frightening.
