The tigers are not leaving Sam alone. Even though Sam never stayed in the sights of the tiger and the cultivators also didn't manage to catch him in their sight, he is still being sensed faintly even without any contact with the trees and the ground.
Sam thought of how to escape and soon found a way, he came to the area where Sam found some traces of claws and smell of urine.
He entered into another beast's territory and from the looks of it, the beast has the same habits as a canine.
Sam activated his Raiju aura showing his weak strength as he drifted into the territory. After he went deeper, but not deep enough to piss the beast off, he saw that the tigers halted in their tracks and didn't want to come in.
Even the riders on their backs are looking at the scene curiously. They didn't speak all this while for some reason and even now they are not making a single sound.
