Rex has felt helpless a moment before when the thought of not being able to get back to the castle and notify the others lingered in his mind, but now he was not lost anymore. A convenient meeting between him and Delta happened, and the journey has become way faster compared to earlier.
If before he would arrive back in a few days, now he can arrive back at the first streak of light.
"Keep going straight, when you see a river turn left," Rex told Delta the way while pointing with his index finger. His body doesn't move at all, he was lying on Delta's back with a tired and pale expression on his face.
Due to the pain and fatigue gnawing at his body, he was not able to keep his body straight.
Rex can only lie his chest and head on Delta's back while his arms and legs dangle on the sides, he has little to no strength left. It would be bad if they encounter a problematic opponent throughout the way, so they have been taking a longer but safer route.
