Yang spent the rest of the day resting and getting to know her new partner. Penny had initially been shocked at her predicament. The last memory she had was entering the ring to fight Pyrrha. That wasn't so bad, Dr. Marcin had been worried that her memory core would be far more corroded. Though Penny was initially distraught at the situation, she quickly adapted. The doctor had added a hologram projector for her, which allowed her at least the mirage of self. Yang did think it was a bit creepy to see Penny's old body spontaneously appear to talk, but it gave her something to speak to other than her arm. They took a few days to get in sync combat wise. While Yang was the predominant force when it came to movement, Penny did have the ability to move herself and could act completely independently in combat if she wished. While this initially hampered them, they found their rhythm while they trained at a new dueling platform that Dr. Marcin had put together for them.
Yang panted with exertion, the dummy spinning in all directions. Penny's hologram observed from the sideline, clapping silently whenever Yang executed a particularly fast or crafty block. It was the only way she could comment on Yang's training without breaking her concentration. Yang executed a quick flip, planning to kick the middle post away from her while simultaneously dodging the upper portion. Things went wrong when her foot failed to connect and switch the direction of the middle bars as planned. As Yang bent her head back, she saw a blade mere inches from her face and approaching quickly. There was no time react, but luckily she didn't have to. As her left arm continued to the ground to finish the flip, her right arm rose seemingly on its own and caught the incoming blade. Without missing a beat, Yang used her new hand hold to twist out of the hurricane of oncoming blows.
"I'm sorry," Penny squeeked, "I didn't mean to interrupt. You looked like you needed help." Yang was far from angry.
"That. Was. Awesome! Penny, how did you do that?"
" Well, all my scanners are intact. I could tell you were going to miss the kick, as well as the impending result. So I took action."
" I want to try something. Are you up for more of that Penny?"
"Absolutely! But are you sure you want me moving your arm that much?"
"Penny, it isn't 'my arm'. It's you. We're partners now, and we need to learn how to work in tandem. It can't just be me throwing punches and you just watching. You aren't a spectator in this. So, are you read?" The hologram Penny was projecting smiled a wide grin before fading away.
"I'M COMBAT READY!" With that Yang walked back up to the dueling platform and started it spinning again. After a few seconds to pick up speed, Yang stopped moving and closed her eyes. Penny reacted beautifully. Yang felt her move to block three hits in rapid succession, then heard a pressure release as Penny deployed her daggers. The daggers acted as tertiary limbs, blocking points that Penny couldn't quite reach with Yang perfectly still. Yang felt the speed of the spinning grow in intensity. She decided to see all that Penny could do. Without warning she leapt backwards.
"Penny fire the cannon," she said quietly as she continued to arc through the air.
"Right!" The blades retracted to about three inches from her forearm and began to spin rapidly around it. As Yang landed she pointed her palm at the training dummy and was greeted immediately with a bright pulse of green light. Her eyes dimmed momentarily from the aura drain, but she quickly recovered. What she saw was a thing of beauty. Roughly a third of the dummy had been reduced to slag. Beyond that she watched as a tree collapsed, its mutilated trunk crumpling under itself. She took a breath and activated her semblance. The amount of aura that the cannon drained had apparently been immense, she could feel her muscles tighten with newfound strength. She lept back towards the dummy and swung Penny wide toward it. without any communication, Penny shifted all three blades to the inside of Yang's forearm. The combination of the blades and Yang's immense strength cleaved the top off the dummy as if it were hot butter. Without missing a beat, Yang pulled her normal arm back and batted the free chunk of the dummy into the forest. Yang was the first to laugh. Penny quickly followed. Both had forgotten what it had felt like to feel this powerful, this in control. It felt good.
The doctor had promised to remain at his lab, never more than a scroll call away. He hated to watch Penny leave, but she was meant to save the world. He also had the utmost confidence in Ms. Xiao Long to protect his daughter, she was an exceptional fighter in her own right. He sadly waved goodbye as Yang and Penny began their journey.
Yang had walked in silence for around an hour when Penny's hologram popped up beside her.
"So what's the plan Yang?" she asked, beaming.
"It's time to get the team back together, Penny. I don't know where Ruby is, but at least she has Ren and Nora with her. She isn't in immediate danger. Weiss is safe with her father, it's just a matter of smuggling her out of Atlas when we get a chance," Yang's voice hardened, " that only leaves one to find, and I don't think she wants to be found. But she owes me answers, whether she wants to give them or not. It's time to find Blake."
"Do you have any idea where she is?" Yang gritted her teeth.
"No. The last place anyone saw her was beacon, we'll have to start there."
"Beacon is still crawling with grimm, Yang."
"That's why I'm worried. She doesn't have any backup. I don't know what she's doing but she won't last long if she stays there. Whether she wants it or not, she needs her team."
