Sha Chen's mood was somewhat heavy.
He clearly hadn't expected that Sun Wukong too might have been breached by Zhunti, which could potentially spoil his plans.
Although Zhunti had sworn his assurances regarding Jin Chanzi, Sha Chen wasn't worried because he was more confident that, although Jin Chanzi might be pressured by Zhunti to resume his Buddhist cultivation for the time being, his heart had changed.
Even if Jin Chanzi remained Monk Tang at that time, a change of heart meant he was no longer aligned with Buddhism in spirit.
The one thing that truly worried Sha Chen was Sun Wukong, a ticking time bomb.
He had the least interaction with him, but his investment was no less for it.
He had intentionally arranged for his alter ego Li Bai to interact with Sun Wukong and to foster his growth, thus establishing an emotional bond.
Later, to diminish Li Bai's presence, he even told Sun Wukong the truth, letting him know that it was he who had always been aiding him.
