Internally, Daniel wasn't as confident about his side as he appeared to be.
He was more than aware of the level of power the king possessed.
What he was hoping to achieve by showing the dead monsters to the leaders of the tribes, was for them to come to admire Daniel enough to subconsciously accept him as their leader, and obtain the bonus in battle prowess that the rest of Daniel's group received.
The King of Monsters was currently looking back at Daniel with intrigued eyes. He could not understand who this twenty years old man was. How he was able to grow in power so quickly, or how everything he did was easily countered.
But aside from some interest, he felt no other emotion towards him. Just like Daniel, he was absolutely aware of the power he had, and the distance wasn't something that a group of four or five late or peak chief warriors that cooperated to kill him could compensate.
