Although Duan Ling Tian was young, Sun Yu Qian respected Duan Ling Tian and addressed Duan Ling Tian as 'senior' due to his strength. Moreover, in his eyes, Duan Ling Tian was his savior. As such, he naturally spoke up to reassure Duan Ling Tian, saying that Duan Ling Tian could also leave the Cyclic World and go to the Outer Boundary through the Sun clan's Transportation Formation.
Seeing how insistent Sun Yu Qian was, Duan Ling Tian no longer stood on ceremony. He said, "Since that's the case, I'll have to trouble the two of you. On account of the two of you allowing me to use the Sun clan's Transportation Formation to go the Outer Boundary, please consider the favor repaid. We don't owe each other anything after this."
