[No system + single female protagonist + upgrade flow]
After traveling into this world for eighteen years, everyone will awaken a [Gate] after adulthood, which replaces the spiritual root and realizes the cultivation of immortality by all people.
Others are either the Fire Gate, the Water Gate, or the Dark Gate, but Mo Yuan is different. He is the rarest one - the Gate of Space.
"What door is yours?" The teacher asked him.
"Bullshit." Mo Yuan answered truthfully.
"Bullshit?" Hearing this, the whole place fell silent.
"It turns out it's a Void Sect without any attribute abilities, but it's okay. Don't be discouraged. Void Sects can also build foundations and are no weaker than other sects." The teacher patted his shoulder and comforted him gently.
"No." Mo Yuan shook his head slightly.
The teacher paused: "Didn't you just say that it was empty?"
Mo Yuan nodded: "Yes, the gate of space."
As soon as these words came out, the whole place fell into silence.
Teacher: "?"
Students: "What is this guy talking about?"

In fact, Mo Yuan still has a secret that he has not told, that is, there is a door in his body that can ignore taboos and offset side effects. When others are still weighing whether to use forbidden techniques in this death battle, Mo Yuan's starting move is ten forbidden techniques...
(The introduction is weak...)
