Spirit Worm.
This was the name sent by Sos, whose true form whereabouts were unknown, after Chen Zhixing retrieved this worm from Zhang Wen's mind.
The Spirit Worm, which appears like a caterpillar, behaves much like one in reality.
It parasitizes the Sea of Consciousness of others, thriving in its caterpillar state by devouring the scattered thoughts of others, and while doing so, it excretes some evil thoughts to pollute the host's Sea of Consciousness, making the host irritable, angry, and impulsive.
