Seven Deadly Sins System

Warning: This chapter should be read before the previous chapter, [500 Years].

The order of these chapters is messed up because of a mistake with Inkstone and I can't delete them because I'm afraid that some readers may be confused and buy the same chapter twice.

Chu Wuyao leaned back in the chair with a serious expression on her face, while her fingers rhythmically tapped on the wooden desk in front of her.

"It seems that my current cultivation is too low and my skill proficiency is not enough to complete the experiment...", Chu Wuyao thought and opened the book in front of her, picked up the pen and started writing down her findings.

"Experiment Number 1."

"Hypothesis: Through a combination of the Blood Essence Analysis skill, the Blood Slave Creation skill and the Devil bloodline, it is possible to create a Human-Devil hybrid."

"Result: Although the experiment didn't result in the test subject's death and it has obtained some Devil characteristics, it failed to become a Human-Devil hybrid."

Writing this, Chu Wuyao stopped for a split second, but then continued.

"Moreover, for some unknown reason, the test subject's mental stability seems to have deteriorated as a result of the experiment."

"Conclusion: Although the idea of combining the Blood Essence Analysis skill with the Blood Slave Creation skill and the Devil bloodline seems to be possible, more experiments are needed to confirm it."

Chu Wuyao's right hand moved dexterously, writing down every single one of her thoughts and guesses on the first page of the thin book.

In fact, since Chu Wuyao obtained the Blood Slave Creation skill and awakened her Devil bloodline, she had always had the idea of turning other people into Devils, or at least, Human-Devil hybrids.

However, it was only after she obtained the Blood Essence Analysis skill and she became a little more familiar with her Devil bloodline that she finally chose to put that idea into practice.

Luckily, just when she was wondering how she could obtain a suitable test subject, Lu Yuan arrived and solved her worries by "gifting" her Yue Zhilan.

Otherwise, it wouldn't have been so easy to conduct this experiment.

After all, the test subject needed to have a certain strength and it couldn't be a mere mortal.

After Chu Wuyao put down the pen and closed the book with a wave of her hands, she lowered her head and looked below.

Even without looking, she could feel that her index finger was inside a wet, soft thing, while a smooth object was constantly rubbing against it, leaving behind a sticky liquid.

When she looked down, she instantly found who the culprit was, Yue Zhilan.

At this moment, Yue Zhilan was kneeling right in front of her, holding Chu Wuyao's hand and putting her index finger into her mouth, then licking it.

Her eyes were filled with a strange obsession and her cheeks were flushed, while her breathing was uneven.

When Chu Wuyao looked at her, Yue Zhilan seemed to have noticed it and the movements of her tongue became even faster, swirling around her finger.

Seeing this, Chu Wuyao should have been happy to have a beautiful woman kneel in front of her and lick her like this, but now, a flash of disgust flashed in her eyes.

"Trash!", she couldn't help but scold and kicked Yue Zhilan away.

Instantly, Yue Zhilan's charming body flew across the room and hit the wall, before falling to the ground and causing gravel to fly everywhere.

However, when the dust settled and Yue Zhilan's figure appeared again, no injuries could be found on her body.

In fact, if anyone was here, they would find that Yue Zhilan's aura had somewhat increased compared to not long ago, faintly surpassing the Qi Accumulation Realm and almost reaching the Shackles Realm.

This was not because Yue Zhilan was talented, but the result of Chu Wuyao's experiment.

Although Chu Wuyao felt that the experiment was a failure because Yue Zhilan failed to become a Human-Devil hybrid, Yue Zhilan still managed to obtain some strange characteristics, including a powerful defense and extraordinary healing capabilities.

This should have originally been a good thing, as it proved that Chu Wuyao's idea was indeed correct, but this came with a few side-effects...

"Senior sister Chu, I'm sorry, I didn't mean to."

"I swear! I'll never do it again! Please forgive me!", Yue Zhilan's loud voice reached Chu Wuyao's ears, while her eyes became red and tears started flowing from them.

In the blink of an eye, Yue Zhilan started weeping, as if she couldn't handle all the sadness and had become completely overwhelmed.

Seeing this, Chu Wuyao could only roll her eyes and walk next to her, and then stretched her hand and ruffled Yue Zhilan' hair gently.

"It's okay, it's okay. I don't blame you. As long as you know that you're wrong.", she tried to comfort her.

"You really don't blame me?", in response to her words, Yue Zhilan stopped crying and raised her head to look at her, her eyes filled with expectation.

When she saw Chu Wuyao nodding her head, Yue Zhilan immediately became happy and after she wiped the tears off her face, she jumped at Chu Wuyao and hugged her like a koala.

"Senior sister Chu, you're the best!"

Secretly speechless, Chu Wuyao could only return the favor and patted her gently on the back.

In her mind, she complained that she should have never done that damn experiment!

Yue Zhilan's changed attitude was not a result of Chu Wuyao's "education" nor a result of her change of mind, but the side-effect of the previous experiment.

Chu Wuyao guessed that this was because Yue Zhilan's blood was partly assimilated by her blood essence, making her instinctively feel attached to her.

By now, Yue Zhilan had completely forgotten their previous grievances and treated Chu Wuyao as her idol.

"But why are the people around me getting more and more strange?", Chu Wuyao wondered and subconsciously glanced at the people in the room.

Apart from her and Yue Zhilan, there was a black cat sitting in a corner of the room, its eyes glued at Yue Zhilan and filled with jealously and a hint of murderous intent.

In another corner, a red flag was standing upright, with a small transparent figure floating right above it.

A Devil, a crazy woman, a cat and a Magic Weapon...

Chu Wuyao almost thought that this was the start of a sick joke...

Seeing that Yue Zhilan had calmed down a little, Chu Wuyao gently shook her off.

Just when Yue Zhilan was about to complain, a bunch of souls appeared in Chu Wuyao's right hand and she threw them towards her.

A hint of crimson color flashed in Yue Zhilan eyes and the next moment, the blue hair on her head turned into countless black tentacles.

These tentacles were eerie, covered in a strange sticky liquid and they instantly rushed towards the souls in the air.

The black tentacles wrapped these souls up and brought them towards Yue Zhilan's mouth, which had now turned into a black hole packed with countless razor-sharp teeth, before they threw them in.

As she gulped down these souls, Yue Zhilan's appearance returned to normal and an expression of contentment appeared on her face.

As if she was satisfied with her "meal", Yue Zhilan showed a look of gratitude at Chu Wuyao and soon after, she lay on the ground asleep.
