The opening of the next chapter I'm writing showed Tantai Jin having a moment with the two immortal disciples. One was a disciple whom Zhaoyao trusted beside TTJ in the drama, and they had a close brotherly bond in the OG. The other he talked to was never explored in neither the adaptations despite their history and connection to a certain someone from the past.
For those who know the OG story, you would know the 2 I'm referring to.
