The monkeys were swarming toward Lith while squeaking and jumping. He didn't wait for them to close in on him and charged toward them instead.
Lith had learned about this particular species of monkey. They were territorial, a little too much; they wouldn't stop until the creature that intruded their lands died or escaped out of their sight and they were also way smarter than beasts of the same rank and prowess. Trying to run from them was as stupid as they would keep chasing, and having them lose one's trail was an exhausting and difficult job.
Lith, therefore, didn't run away as he knew it was a pointless thing to do. He decided to fight them head-on because that was much easier. The monkeys in front were low rank, and his prowess of a Rank 6 made him too overpowered against this weak bunch.
