If Han Xuhan provided them with no valuable information, then Feng Jun and his group wouldn't have any reason to risk their lives to help him.
People who understood and operated under the rule of equivalent exchange were easy to deal with.
Han Xuhan knew what Feng Jun wanted, Feng Jun understood what Han Xuhan wanted. There was no reason to act like savages and deceive each other when both parties could reap the benefits with a bit of silent cooperation.
And it took only a single exchange of looks between Han Xuhan and Feng Jun to understand each other's intentions.
Han Xuhan didn't hide much from them. Apart from his tussle with Shen Kai and Mu Ran's obsession with the foggy area, there was no reason for him to keep anything else a secret.
Hearing that Mu Ran was fighting a monstrous, reanimated corpse of a mortal, the cultivators from the Stardust Sect looked rather relieved.
