Han Sen and Qu Lanxi continued their journey, and after a dozen miles of walking, they hadn't managed to find a single iron bug. From his slaying of the tree crabs, Han Sen was able to obtain three beast soul armor sets.
They didn't slay any tree crabs they encountered after that, but snuck around them instead. The sack they had brought with them was already stuffed, so killing more would be pointless.
Han Sen walked past a bunch of Blood-Scale Snakes, too. The groups were too large, however. Fighting them was a dodgy prospect Han Sen was keener to avoid at his current strength.
"That's strange. We really can't find any iron bugs, can we?" Once Qu Lanxi told Han Sen about the large host of iron bugs that supposedly occupied that area of Thorn Forest, Han Sen made doubly sure to scan the environment. It was all to no avail, however.
