When the announcement for the main quest update came, Xiao Tan and Laughing Soul were still exploring the underground tunnel, looking for a way out. Even though the stone told them that they would have completed trekking through the entire cave system in one night and one night, something was obviously wrong with its calculation. Its so-called one day and one night was probably twenty-four hours without stopping to rest. Naturally, Xiao Tan and Laughing Soul could not do that. When their stamina reached the bottom, they had to stop to rest. Both of them were currently level seventeen, so their maximum Stamina Points was 1,700. No matter what, they decided to keep their Stamina Points at least above one quarter just in case they ran into something unexpected. If they did not have any stamina left, how would they survive?
