Han Sen left the shelter with Bao'er. He killed a few primitive class bugs at first, to see if that would draw the ape out.
Not long after, it had indeed come to steal his kills. It crept near to Han Sen and watched him.
It was possible the ape knew Han Sen was special, more accomplished than the others fighters it had boorishly stolen from. This time, it did not make an immediate appearance and try to tackle Han Sen before running off with the goodies; it just waited and watched.
Han Sen was aware of the ape's presence, but pretended he wasn't. If he revealed he knew it was close by, there was a chance the ape would scarper. And if so, he'd most certainly be unable to pursue the ape if it was empty-handed.
Han Sen faced away from the ape, and holding Bao'er, he looked for more prey he could kill. When he started to move, so did the ape.
Han Sen found a black scorpion lying ahead, and noted it was primitive class. He fired an arrow.
