The Spar Arena
William knew the colour appearing over their bodies related to the level of their spirits, the shape of these tattoos with the type of their physical spirits. It was just the same as spirit masters. And from the look of it, he could tell that Lina had the spirit of silver rank.
It was remarkable! Knowing that she never trained her spirit before and reached such a stage was indeed quite the feat. Spirit masters in this tiny world didn't know that the awesome powers Selvators held came initially from the power of their spirits.
As their spirits got mixed with their bodies, forming what was known as physical spirits, their physical strength was directly related to their spirit powers.
William suspected before that Lina's spirit level was bronze just like him. But she was already higher than him by one grade.
And from the shape the lines and tattoos formed, William could tell that she was a steel spirit type. And that explained why she sustained such pursuit before for a long time.
