Yurmuk wanted the chance to be truly one hundred percent chance of hitting him. Only then would he throw that battle axe at him
Killing him in one blow, that would surely embolden his army and the morale shift would be hard for the other deputies of the Khagai tribe to handle.
"retreat" he thought to himself.
Now, after a few minutes of fighting with Yurmuk he also has figured out what kind of warrior Yurmuk is and his pattern.
Ota smiles
"I win this battle" he thought to himself
Neigh!
Ota horse neighed as Ota pulled his horse back.
Yurmuk saw this and he shouted
"Is Ota the Great warrior of Khagai is retreating! Coward! " this time it did not seem like Ota is retreating only to come back and fight him again.
This is Yurmuk judgement.
It is like he is retreating to avoid the sharp edges of his attack.
"he has seen through it" Yurmuk thought to himself
