No need, no want, no worry

Rei woke up as he felt the lack of weight on his chest. Sitting up, Rei yawned slightly as it was the first time he slept in a million years.

Rei got up as he went to look for Bai Wu, it didn't take long for Rei to find her as she returned from the forest carrying some fruits.

"Ah! Lei, you're awake." Bai Wu waved as she jogged over. As she go close to Rei, she blushed remembering what she did and paused.

"Mn?" Rei was confused as to why she suddenly paused in her steps.

"Bai Wu?" Rei asked as he walked closer to her wanting to see what's wrong.

"Ah errr...nothing! Nothing is wrong, just thinking!" She said averting eye contact. She cupped her cheeks as she felt them burn up.

'AAAHHHHH!!!!! Stop blushing cheeks!!!! Bai Wu will get found out!!!' She shouted mentally.

Rei only raised an eyebrow as he looked at Bai Wu cupping her cheeks.

Rei only chuckled as he walked behind her. Leaning forward, Rei smiled.

"Bai Wu?" He said close to her.

"AAHHHH!!" Bai Wu jumped in shock hearing Rei's voice so close to her ear. But as she jumped, her head collided with Rei's head causing her to fall forward.

"Uuuuuu~, why is Lei's head so hard?!"

(╥﹏╥) Bai Wu said as she clutched her head with her hands.

"Hmmm, because I train my body up. We should work on your combat techniques. It'll help you out in the long run." Rei said with a smile seeing Bai Wu's expressions.

"So Lei is teach Bai Wu how to fight?" She asked standing up still rubbing her head.

"Yeah, I'll teach you so that you can protect yourself." Rei nodded.

"But can't Lei protect Bai Wu?" She asked.

"I can, but we need to think about when I can't protect you." Rei said.

'Does Lei mean when Bai Wu had to escape with Lei? So....Lei want's Bai Wu to protect Lei!' Bai Wu thought as her eyes glowed with determination.

"Hmm Lei so shy. If you want Bai Wu to protect Lei just say so." Bai Wu smiled.

"Hmm, half and half. I want you to get stronger so you can protect yourself." Rei said emphasising the yourself.

"Sure sure, so what does Bai Wu need to do?" She ask.

"We're going to have a spar.You attack me with everything you got and I'll see what your capabilities are." Rei said.

"But Bai Wu doesn't want to hurt Lei." She said frowning slightly.

"You think your kicks can hurt me?" Rei raised an eyebrow.

"Oh yeah. Lei has very tough defence." Bai Wu said as she remembered how Rei has a ridiculously high defence.

"Ok Bai Wu is attacking now." She said as she teleported towards Rei. Appearing besides Rei, she kicked out with her right leg.

"Power is roughly Super Rare." Rei muttered as he grabbed her ankle and pulled her towards him. He was about to flick her in the forehead when she teleported behind him again.

"Reaction is roughly High to King." Rei muttered once more as he ducked under her kick.

Seeing that Rei ducked under her attack, Bai Wu brought up her other leg as she created a scissor motion with her legs attacking from two directions.

"Hmm battle instincts roughly Super Rare." Rei said as he blocked the two kicks. Bai Wu bent her back with incredible flexibility as she put strength into her legs trying to lift Rei up and smash him against the ground.

Rei wasn't about to let her have her way as he flicked the back of legs forcing them off him.

Using the momentum of being thrown off, Bai Wu teleported behind Rei as she tried to kick him behind his head.

Rei swung his legs upwards as he countered.

"Hmm, battle instincts are around High to King instead." Rei muttered as he made a mental note.

"Let's test defensive measures." Rei said as he put force into his legs pushing her back, Rei dashed forward as he flicked her forehead causing her to stumble.

"Hmm definitely needs work..." Rei said as he flicked her forehead a few more times as Bai Wu tried to teleport away but was hit each time.

"Lei stop it!! Don't flick Bai Wu's head!!" She said holding her slightly red forehead with tears in her eyes.

"Fine, I'll punch instead." Rei said with a smile holding up his fist.

"Eh? ( ゚ヮ゚)" Bai Wu replied with a dumb look on her face.

Rei was about to move when he scared Bai Wu out of her trance.

"Wait wait wait wait!!!!! Hahaha Bai Wu was kidding...errr flicking the forehead is ok, no problem at all." Bai Wu nodded her head quickly.

Rei raised an eyebrow in humour.

"Really? I was sure I heard you say something about don't flick your head anymore?"

"Nope, Bai Wu didn't say that. Lei must have misheard hahahahaha..." Bai Wu laughed nervously.

Rei chuckled seeing her act like this.

"Fine I'll just use spirit energy to repel you then." Rei said causing Bai Wu's eyes to light up.

"THANK YOU!" Bai Wu said gratefully.

"Alright that's enough. Come on we have a spar to finish." Rei said as he resumed the spar.

He and Bai Wu sparred for a few hours as Rei got a general view on Bai Wu's powers.

"Bai Wu, we'll need to work on your power, defence and reactions the most. However, we can also focus more on speed than defence so that you can evade attackers easily." Rei said as he watched Bai Wu laid on the floor panting and drenched in sweat.

"I'll test your will power later but first get some rest and wash up to relax." Rei said as he sat down on a rock.

"Hmm ok." Bai Wu said as she pulled her tired body away.

"Do you want to join?" Bai Wu asked with a grin.

"Hmm seems like you have enough energy to spar some more." Rei smiled as he turned around. Rei raised an eyebrow as he saw Bai Wu already half way through running away to the lake.

Rei chuckled as he started making a mental status board for Bai Wu.

'System, save this status board if you can.' Rei thought.

[Status board for (Bai Wu) saved.]

"AHH!!!!"

Rei was cut off when he heard Bai Wu scream and ran over to where she was. Having learned his lesson from last time, Rei didn't cover her area with his senses. However, he regretted it the moment he ran towards her area.

Bai Wu stood nude as she slowly tried to dip her foot into the lake.

Rei slapped his hands over his eyes as it made a loud sound from the force and speed.

"Bai Wu, why did you scream?" Rei asked turning around away from her. However, the image of Bai Wu in full nude trying to dip her foot into the lake had firmly imprinted itself into his mind.

"Lake was too cold." Bai Wu said as she turned around to see Rei covering his eyes and facing the other way.

"Lei saw?" Bai Wu asked with a blush.

Rei nodded slowly.

Bai Wu blushed as she slowly sat down into the water hoping it would cool off her blush and hide her body.

"Don't scream out randomly." Rei said as he sat down. He decided to stay just incase something did happen and wasn't just another one of Bai Wu's pranks.

Bai Wu nodded slowly as she submerged her body till her nose was just above the surface. Her entire body felt hot as the cold water didn't help cool her down at all.

"How much did Lei see?" She asked looking at Rei's figure.

"More than what I wanted." Rei said as the image couldn't help but resurface in his mind. Rei shook his head as he tried to get rid of the image.

"You just thought of it again didn't you?" Bai Wu said seeing Rei shake his head.

'Again, why the hell is she so sharp when it comes to things like this.' Rei thought.

"Finish washing up and go have some rest." Rei said as Bai Wu nodded and started to wash up. She couldn't help but blush even more as Rei was near by. Rei on the other hand was the same, just by listening to the sound the lake made Rei could picture every movement. Paired that with the image he couldn't get rid of, there were no different to seeing it with his own eyes and imagining it.

'Fuck!' Rei cursed in his mind as he felt a certain body part react.

'No need, no want, no worry. No need, no want, no worry. No need, no want, no worry....' Rei started to chant a mantra in his mind as he tried to clear himself of his dirty thoughts. It started to work as he could feel his 'little brother' calm down once more.

"What are you doing Lei?" Bai Wu asked as she finished bathing and got dressed. Her body was still wet as the clothes stuck onto the curves of her body.

Rei's senses were tuned to the max as he could feel the water elements trace the entirety of Bai Wu's body. Especially since she was standing so close to him.

"Nothing, I'll be right back." Rei said as he stood up and walked away quickly.

"Lei is flustered." Bai Wu muttered though she was confused.

'Hmm charm never worked before since Lei's will power too strong. Charm also need target to find Bai Wu attractive. Does Lei find Bai Wu attractive?! Is that why Lei became flustered?!' Bai Wu thought as she blushed happily finding out that Rei is attracted to her.

Rei on the other hand....

'No need, no want, no worry. No need, no want, no worry. NO need, NO want, NO worry. NO NEED, NO WANT, NO WORRY. NO NEED! NO WANT! NO WORRY!!!!!' Rei screamed out in his mind as he tried to calm the revitalised body part.

Walking into the forest, Rei smashed his head against a large boulder destroying it as he breathed deeply.

"Why the fuck is my body like this...this never happened in 7 sins world..." Rei muttered as he clenched his teeth. He sat down in a lotus position as he chanted the mantra to calm his mind. As a master of body control, Rei only took a few minutes as he exerted his will power forcing his 'little brother' to calm down.

"Fuu..." Rei breathed out deeply as he prepared to walk back. This time however, he made sure to keep a constant control over his little brother.

The first thing Rei saw when he returned was Bai Wu still sitting with her wet clothes sticking to her body. Seeing her sit with wet clothes, which are almost see through, almost made Rei lose control instantly even with his will power.

"...Bai Wu, why haven't you dried your self yet?" Rei asked exerting a continental amount of will power over his little brother while he held a slightly awkward smile.

"Mn? Oh yeah, can Lei help Bai Wu?" She asked seeing Rei's awkward smile.

"I'll help with the hair but you can dry your body." Rei said throwing a towel to Bai Wu and walked away.

'Hmmm, seems like Lei has his guard up again...oh well at least Bai Wu made Lei react.' Bai Wu thought with a smile as she dried herself up.
