Sun Mo is running around the forest for his life because he can't sense Gani Bartolome anywhere and if he cant even sense or see his enemy, then how can he even fight?
Sun Mo tried to do the same as Chiyou, he also tried to sense his surroundings to find Gani Bartolome but he couldn't do so.
So, he is running for his life while he also keeps avoiding the arrows that come after him.
*boom
boom
Booom*
One after another big explosion took place but Sun Mo managed to avoid all of the arrows that are thrown at him and soon he reached a small mountain which is attached to the big mountain, where he was, and then he jumped off the small mountain.
The main reason he was running around the forest is because he wanted to get into the open field and once he is out in open, he can find Gani Bartolome.
