For some reason, the past had resurfaced in Zero's mind. Maybe it was because he was close to achieving his goal, maybe it was because he could see that dreaded weapon in the ground.
The one that had nearly taken his life, either way those days were soon to be behind him, as he had one last thing to do. There were no more requests, this was it.
Pretending to swing the sword towards Peter, Zero then swung it behind him, as he aimed right for Erin's neck. He knew about her ability, because he knew a lot about Leo as well. She was able to sense any kind of energy fluctuation, allowing her to predict when an attack was coming before it did.
Which was why, with this strike, the only thing Zero used was the first stage of Qi to enhance the strength of his muscles and only that. He condensed his Qi down, focusing on not making it move a tiny bit, and swung the sword.
