Tower

On the outside, Tower seems to be a figurine shaped like a tower (Who would have guessed it) in a rundown shape. Early on we are not too sure of its shape but later is confirmed to be a Pagoda.

Tower had followed Chen Feng ever since he could remember, and previously had showed no signs of abnormality. We only see it activate when Chen Feng is struck by the lightning of an ancient tree undergoing Lightning Tribulation. Absorbing the Lightning Tribulation and awakening.

Tower is a mysterious artifact and treasure related to Chen Feng's past and also linked to his father In some important way.

Tower is also an existence of treasure beyond anything the Eternal World should normally have, but due to some unknown war or battle in the past is heavily damaged all the way to the quality of a Prized Artifact, and only gets stronger through the absorption of either other treasures or rare materials. Later being promoted to a Sacred artifact tier existence after absorbing the Immortal Energy within Pot Mountain.

His voice is that of an old man you would expect to be an old scholar or a teacher, but later after reaching power level equivalent to a Sacred artifact he regained the ability to from an appearance inside itself, which surprisingly resembles that of a young boy with a prominent smile on his face. The response given when asked why Tower chooses such a form he responds saying that ever since he was created he had always had such a look and saw no reason to change it.
