The woman was strong. Stronger at least than anyone else he had fought until now. But still, she wasn't strong enough to fight him should he fully use his physical strength on top of the sword.
Having to restrict his own strength was more annoying than it was helpful. He wanted to fight to his content.
Alex pushed the woman back, but she came back right away, stabbing toward him. Alex was about to block, but the spear suddenly blurred. To his surprise, the spear had gone invisible.
The woman held her hands in the same position, but there was nothing to say whether she held the spear in her hand or not.
Alex waited until she arrived within his range before searching for the spear with his Spiritual Sense. He had a fraction of a second to locate it and then stop it.
He parried the spear at the last second, redirecting it to the side.
