Li Yuanba did not wait for the Great Cultivator Spirit Medicine to mature at the Great Cultivator resource point, as he was certain that news of this place would soon spread.
Next, he feared that Great Powers would come to investigate. Anyone who learns that a Half-step Great Power has appeared within their domain would come to check.
Upon seeing that the Great Cultivator Spirit Medicine needed several more days to mature, he decided to leave early.
Though the Duke of Thunder's combat power isn't weak, he learned the true strength of the Duke of Thunder from this battle.
The Duke of Thunder's combat power is roughly equivalent to Half-step Great Power strength, and is primarily close combat.
The Duke of Thunder isn't without ranged attack methods, as thunder is a ranged attack. However, in Li Yuanba's view, its power is far less than his close combat strength.
