It's the Emperor?! (1)

Approaching the mark, Lin Yan saw that there was a line of small words drawn by a weapon beside the mark. It was the words left behind by Liu Lanqing. The general meaning was that they would leave first. If Lin Yan saw the words, he had to follow carefully.

Liu Lanqing and the others naturally did not know about the Dragon Absorbing Water Pond. However, Lin Yan had mentioned it to them when they arrived at the ruins, so they knew they should leave in this direction.

Lin Yan immediately dove into the water and swam towards the tunnel.

The ground collapsed, and even this tunnel was buried. However, Liu Lanqing and the others had already left previously, so they should still be able to safely reach the underground mine.
