Reincarnated as an Energy with a System

Ning was running across the city with a massive sound coming off of him. Wherever he found zombies, he would kill them and take away the Yin Qi from them. 

Very soon, he came across a problem. It was night time and natural yin qi was everywhere. He couldn't separate Yin Qi from the Unique Yin Qi. 

So every once in a while, he would stop the technique. The Natural Yin Qi would disappear in the atmosphere, while the Unique Yin Qi would just attack his body, rotting it very fast. 

He would have to run away each time and gather the Unique yin Qi even further. 

"This should be enough," he thought as he started the Sun God's Morning Cleansing technique. Soon, the Unique Yin Qi was destroyed. 

Once it was gone, he started going to a different place and doing it again. He didn't know any other way to remove this Unique Yin Qi, so he didn't even bother trying to do anything other than help the people right now. 

The fire had gotten under control a bit, but the number of zombies were increasing. Everywhere he went, he shouted at people to not touch the dead. The information was slowly being spread around, but that wasn't enough. 

'It won't be enough until the people behind this are taken care of,' Ning thought.

Ning had started from the outer circle of the city, so it was taking him time to get towards the center. It was taking him even longer because he was helping people along the way.

He barely reached the outer circle of the inner city when he was done with using the Sun God's Morning Cleansing technique for the 7th time. 

He looked around at the death and destruction. This was just too much. People were running around, screaming as dozens of zombies followed behind them.

"The enemy gets stronger the longer we keep this up," Ning thought.

BAM

A house next to him was brought down as a man was thrown through it. Ning immediately ran towards the man after seeing that he was part of the Pure Cleansing sect.

"Brother are you okay?" Ning asked while checking for any injuries or bleeding. 

"Urghh… I'm fine.  She's just too strong for me," the man said as he got up. 

"HAHA, you cannot beat me. Just give up and become my servant," A voice spoke from beyond the dust and smoke where the house had just fall from. 

Ning turned around to see a woman walk out of it. The woman had an evil smile and a head full of unkempt hair. However, the thing that caught Ning's eyes was the slightly blue skin. It made her seem like she wasn't human, or if she was, she had just come out of the refrigerator. 

"Like hell, I will," the man stood as he held her staff in front of her. However, Ning could see that the man was clearly scared. 

'Just how strong is she?' Ning wondered and silently checked the lady. 

7th Qi Condensation Realm.

'That's not very strong. I'm stronger than her,' Ning thought. He then turned to look at the man to see if he was weaker than the woman. 

7th Qi Condensation Realm.

'What?' Ning was surprised. 'How is someone is the same cultivation base stronger than the other? Does she have higher body cultivation?' Ning silently checked, but neither had body cultivation.

"Hiyah!" the man shouted as he ran forward and swung his staff horizontally. The woman stepped back and swung her sword as well. 

The man had the range, but the woman had the speed. She started closing the gap quickly and slammed away the staff. The staff skipped out of the man's arm and flew to a wall near them. She then cut the man's leg, stopping him from moving any further.

The woman didn't continue, however. "Alright, become my servant," she said as she went forward put her palm on the man's bald head. 

BAM

Ning kicked her in the stomach, but the woman was fast enough and used her sword to block his attack. "Hehe, I was wondering when you were going to help," she said. 

'She survived that?' Ning said in surprise. His body cultivation was way higher than her, yet she had survived that. 

'Is it a skill?' he wondered and quickly checked her lists of skills. However, he didn't know what many skills did and as such didn't know what hers did. None of the skills there were self-explanatory at all.

"How about you become my servant as well?" the woman said as she licked her lips. 

Ning pulled the Blood-red spear from his storage and said, "No thanks. I would rather die than have anything to do with a blue-skinned B*tch like you."

The woman's smiling face immediately turned ice-cold as she ran forward and slammed her sword at him. Ning blocked the sword and parried it with his spear as he started to move it around. 

He swung it from the side and attacked her. The woman blocked it directly with her sword. Ning took the spear back and spun it around to attack from the other side. 

The woman blocked it again. However, before she was even ready, the spear came from the other side, aiming for her head.

The woman dodged but was still cut a little on her face. 

Black blood started spilling out of her cheeks. The woman placed her palm on her cheeks in disbelief at what had just happened.

"You dare cut my face!" the woman said angrily and her sword started lighting blue. Ning didn't know what she was doing, but he wanted to finish her quickly. 

So, he brought the spear back for a final blow. 

However, the woman swung her sword before his spear could reach her, and immediately large blue energy escaped from it throwing Ning all the way to the wall on a house on the other side. 

He stood back up and soon realized his mistake. 

"You poor fool. You didn't even remember that you had someone to protect," she said as she placed her palm on the bald man on the ground, and soon, his head started growing wrinkled and decrepit.
