Tang Yin did not return to the same cave, he chose to carry on towards Treasure Bank City.
Every time he thought back to what happened with the old man and his disciples, a bitter smile appeared on his lips. Tang Yin was very astute, by now he had pieced everything together.
From Qin Yan's memories, he had learned that her Master and Senior Brothers had come out on a mission, It was more of an errand. Qin Yan had wandered off from her Master's temporary cave abode, and her 2 infatuated Senior Brothers naturally followed along.
Qin Yan and her Senior Brothers were far away from their Master's cave when the rain poured heavily. Tang Yin's cave happened to be near which was quite unlucky.
After Qin Yan saw Tang Yin, she thought of him as some weakling since Tang Yin did not spread out the aura of his cultivation. That's why she had intended to plot against him and take over his cave for shelter.
