More importantly, the virtuous lamia was also three-dimensional.
Actually, it was completely understandable that Fairy Virtue was in three-dimensional mode. In her previous life, Fairy @#%× was a Ninth Stage Tribulation Transcender of the ancient Heavenly City. Moreover, she had come into contact with the merit network long ago and knew about the path to immortality hidden in the merit network that had yet to be verified by anyone.
However, she did not choose to take this path of immortality and left it in the Ninth Stage Tribulation Transcender Realm. Now, the path to immortality hidden in the 'network of virtue' was given to Sage Monarch Melon Eater, who was transcending the heavenly tribulation of the Ninth Stage.
Before she died, the virtuous lamia was already a Ninth Stage Tribulation Transcender, so she was naturally able to maintain her three-dimensional form in the Tribulation Transcender Void.
