Lin Chen still trusts Sun Yixiao quite a bit, after all, the two of them have a considerable relationship.
Most importantly, Lin Chen now possesses great strength. If Sun Yixiao has any intentions, he would need to weigh them carefully.
This journey across the Star Sea is extremely dangerous, and Lin Chen will sooner or later have to wield the Linglong Tower. So in the presence of a familiar acquaintance, there's no need to deliberately hide it.
"Senior, you must remember, I saved your life."
Sun Yixiao nodded vigorously: "Yes, yes. Although I'm the Saint of Thieves and usually like to steal things, I still have ethics. Don't worry, I absolutely won't talk about it. If I break this vow, may the heavens condemn me, and let me never steal a thing for a lifetime."
Lin Chen responded with a hum: "We are old friends after all, I naturally trust the senior."
