"I wonder if the Goblin Wolf Cavalry that I intentionally spared just now will be able to successfully send a message and bring troops to besiege me."
Zhang Yanhang was indeed looking forward to being besieged, but he was more excited about what good things might come out of the treasure box dropped by the Goblin Wolf Cavalry.
After releasing the Death Wave Skill, Zhang Yanhang had landed on the ground and was quietly waiting for the treasure box to refresh.
Yes, this is also a drawback of the Flying Technique, as he still needed to return to the ground to pick up a treasure box since Zhang Yanhang hadn't eaten the rubber fruit and couldn't extend his arms.
As for whether Mage's Hand could help Zhang Yanhang pick up a treasure box? It technically could, but it was rather slow; after all, the original purpose of Mage's Hand was simply to assist the mage with menial tasks, such as passing materials or a magic scroll.
