It was the emperor of the Roman Empire, Commodus, who spoke. Hence, Sartonilos could not disobey the order. He then glared at Zhang Heng with his murderous stare and returned to where he stood helplessly.
Sartonilos felt that although Commodus stopped the battle, it seemed he was leaning a little more towards Zhang Heng. However, he was not an idiot. He quickly figured out why Commodus stopped the battle. At the last moment of the fight between the two, Zhang Heng transformed his hand into a hand knife. And he slit his neck with it. If he held a knife or a sword in his hand, Sartonilos would have been dead by now.
