Lancelot "awoke."
To be precise, only his consciousness awoke. Lancelot found himself currently nothing more than a glowing shadow with a vague outline, situated on a barren island. In the center of the island floated an object he was very familiar with—a gigantic azure bamboo scroll, which was the treasure left to him by Han Tiansun.
So it was not difficult to guess where this place was: deep within his own Sea of Consciousness. In the past, when he occasionally "descended" here unintentionally during cultivation, he struggled to stay for long. According to the bamboo scroll's records, one must reach the Core Formation Stage to freely enter their own Sea of Consciousness space, and Divine Sense is precisely the focus of cultivation at that stage.
