Tang Yin did not return to the old woman's cave on Four Seasons Island. Instead, he headed towards the dome of light so he could leave the island and start the last part of his plan.
Once Tang Yin reached the dome of light, a gap opened. He moved through the gap and left the island. Just as he was about to speed off into the distance, the aloof voice of the Elder overseeing the dome of light rang out.
"Eh, didn't you just enter the island? Why are you leaving in such a hurry?" The Elder asked, there was suspicion in his voice.
"Senior, I came back to the island to collect the rewards of my mission and to make an exchange. Now I'm leaving to complete another mission I've accepted." Tang Yin made up another lie. To make any lie believable, one had to mix it in with the truth.
"Hm, Alright. I won't pry into your business." The Elder left after a cursory glance.
Tang Yin continued to leave the island. He did not expect the Elder to stop him, but in the end, everything worked out.
