Matthew had also tried to hang himself from a tree by only using one hand and relying on the spider's setules on the palm of his hands to keep himself from falling, which surprisingly worked even though Matthew had predicted otherwise when he remembered how heavy his current body is. But the spider setules proved that he was wrong and showed their true strength, enabling Matthew's whole body to hang without slipping his hand.
Before he tried to jump between trees and possibly become the one and only spidermeleon in this world and swing his body using the silk glands on his wrists, Matthew had tried whether the silk he produced from his silk glands was strong enough to hold the weight of his body.
Which made the three kobolds look at him even with more questioning eyes when they saw a thin white line had suddenly come out of Matthew's wrist and shot forward, sticking itself onto a tree branch.
