Lin Chen was truly willing to let go!
Although the Sun Moon Divine Dragon Cup is an Innate Spiritual Treasure, it is clear that one's own life is obviously the most important.
The things that a dying quasi-saint wants to do are likely not trivial matters.
As a top big shot of the Bitter Sea Immortal Domain, the True Person Tai Xu definitely knows Taoist Duan Tian. Telling him about this and asking for his idea, Lin Chen believed, would be very secure.
As for whether the True Person Tai Xu would trick Lin Chen, Lin Chen had not considered this point.
If it hadn't been for the True Person Tai Xu, Lin Chen would have died at the hands of the Sea God long ago. If the True Person Tai Xu wanted the Sun Moon Divine Dragon Cup, he would just give it to him. Lin Chen would do so willingly, after all, he owed him a life-saving favor.
