Bad Luck (1)

They returned the way they had come and chased after the fork in the road where Estelle and the others had left.

The passageway was very wide at first, and there were two sets of footsteps on the ground. It could be seen that Estelle's team had walked side by side in two columns. However, after walking forward for a while, Yu Huang discovered a small pool, and the footprints on the ground had long been washed clean by the water.

This was the bad thing about underground passageways. There were too many underground rivers. Every day, the water rose and fell, so it was easy to erase the traces of footsteps on the ground. Yu Huang and the others discovered that the stone wall of one of the passageways had been marked by someone. They followed the marks and chased after them for more than an hour. They actually discovered that there were also marks on the stone walls of the other passageways.
