The small snake tried its best to straighten its neck, attempting to give itself a more menacing countenance.
This was also the most common posture of serpent-like creatures when encountering an enemy. However, because it wasn't that large and wasn't poisonous, it was just a bluff no matter how much it changed its posture.
From the expression on Ma Lu's face, it could be seen that he did not take the small snake's threat seriously. However, his ease only lasted for a few seconds, and then he heard a rustling sound.
If the rustling sound before was like someone shaking a piece of white paper, now it was like tens of thousands of pieces of white paper being shaken together. The sound was not loud, but when it gathered together, it made one's hair stand on end.
Ma Lu felt all the blood in his body freeze, especially when he saw the scene in the tunnel through the light of the flashlight.
