Seven Deadly Sins System

Since her body cultivation had already reached the peak of the Qi Accumulation Realm, even though Chu Wuyao didn't have the Sin Points to improve the Blood Demon Body, it only took her a few days to breakthrough to the 10th Level, which was equivalent to the Shackles Realm.

Chu Wuyao felt the strength of her physical body and the boiling blood that rushed everywhere in her body, and she felt that she could now kill a Shackles Realm cultivator with just a punch.

Of course, this was just an illusion caused by her sudden increase of strength and she soon calmed down.

"Although my current physical strength is lower than the physical strength I obtained in my True Form, it is still very powerful."

"Moreover, as my strength increases, the power of my True Form will also increase and I will be able to stay in that form for a longer time.", Chu Wuyao analyzed.

If that was just it, Chu Wuyao would have been very happy.

But...

"...But I have reasons to suspect that I'm going more and more astray.", she thought speechlessly as she looked down at her own body.

At this moment, every inch of her body was covered in illusory white scales and her figure was surrounded by faint white mist, making her look as if she was piloting a mecha.

If any outer disciple was here and saw her current appearance, they would find that these illusory scales were quite familiar, very similar to the scales of the Mist Dragon that appeared during the sect competition.

With a thought of Chu Wuyao's mind, the illusory scales suddenly disappeared and she stared at the skill description in front of her eyes.

[Blood Essence Analysis: By swallowing the blood essence of any bloodline creature, you can analyze its bloodline and obtain some of its abilities. If this skill is practiced to perfection, the cultivator will be able to transform into that creature.]

[Note: You can only analyze bloodlines that are weaker or equal to yours.]

Just like what happened when Chu Wuyao practiced the Blood Demon Body for the first time, with her breakthrough, she obtained one more skill.

When she read the the skill's description, Chu Wuyao unconsciously thought of one of the options she had while advancing to a Lower Devil, becoming a Shapeshifter Devil.

According to the system, Shapeshifter Devils were able to mimic other creatures' appearance and use their abilities.

She remembered this because Chu Wuyao found this ability quite interesting at the time.

Now, when she saw this skill, she had a strong hunch that the reason that that option appeared was exactly because of it.

"Since you can only analyze bloodlines that are lower than yours, this skill is quite useless for the vast majority of cultivators."

"After all, most cultivators are humans and the cultivators that have awakened special bloodlines are very rare."

"But for someone like me, this skill is perfect."

Chu Wuyao knew very well that the Devil Bloodline was a top-level bloodline not only in this world, but in the entire universe.

This could be seen by the fact that she was able to analyze the bloodline of a Mist Dragon, a creature whose bloodline is known to be extremely powerful in this world.

Thinking of powerful bloodlines, Chu Wuyao suddenly remembered something.

With a thought of her mind, a space crack appeared right in front of her and the next second, a black creature flew out and rushed towards her, as if it was pouncing at its prey.

Chu Wuyao however remained calm and stretched her hand, clutching the creature's constantly swinging tail.

"Master, show mercy!", Cthulhu begged in a loud voice.

Chu Wuyao chuckled when she saw its reaction and then threw it to the ground.

She didn't talk any nonsense and went straight to the point.

"Give me some of your blood essence."

"No! Master! Doing so will cause my strength to decline and I will have to spend a lot of time to recov-", Cthulhu wanted to argue, but when it raised its head, it found that Chu Wuyao was silently looking at it.

For some reason, when it looked at its master, it felt that she had become a little more majestic.

This was not because of the improvement of her strength, but because of a more hidden, a more deep-rooted reason.

Cthulhu felt a little afraid as it noticed the trembling of its bloodline.

"Master, don't worry! Your faithful servant will not hesitate and will sacrifice everything for you!", it yelled and with moist, reluctant eyes, it opened its mouth and spat out a scarlet drop of blood.

This drop of blood was not ordinary blood, but its blood essence.

When Cthulhu felt the decrease of its strength, it became heartbroken.

Stretching her hand, Chu Wuyao grabbed the drop of blood essence and glanced at the black cat with some curiosity.

Despite the fact that its aura was fluctuating and had become a little unstable, Chu Wuyao noticed that its aura was stronger than ever before, heaving reached the 8th Level of the Qi Accumulation Realm.

This made her wonder if her perception was wrong.

After all, just not long ago, Cthulhu was only at the 5th Level of Qi Accumulation.

While it was wiping its tears with its small paws, Cthulhu seemed to notice Chu Wuyao's doubts.

"Master, you don't know. In fact, the Devil World is many times larger than this world and there opportunities everywhere."

"Most Devils don't practice like humans, but they are constantly looking for these opportunities."

"According to my bloodline inheritance, there was once a Young Devil that was lucky enough to obtain an immortal fruit and after swallowing it, they instantly advanced to a Higher Devil."

"My mere progress is nothing.", Cthulhu hurriedly explained.

However, although Cthulhu didn't mention it at all, Chu Wuyao understood that these opportunities should be accompanied by danger and to obtain them, one had to go through endless killing.

Her eyes when she looked at it changed a little.

She didn't expect that this seemingly unreliable, stupid cat was somewhat talented.

Suppressing these thoughts, Chu Wuyao glanced at the drop of blood essence in her hand and then, she put it in her mouth and swallowed it.

Immediately, she felt the blood inside her body rushing towards her abdomen and wrapping this drop of blood essence, as if it was swallowing it and forcing it become a part of it.

This process was quite fast and it only took a few seconds until the blood essence completely disappeared.

Instantly, Chu Wuyao noticed that there was another bloodline that had been "analyzed" and if she wanted, she could partially transform into that bloodline temporarily and obtain some of its abilities.

Of course, she immediately chose to do so.

She was originally expecting that the transformation would be similar to that of the Mist Dragon bloodline and she would obtain some illusory characteristics of a cat, like claws or fur, but she soon found that she was completely wrong.

Under her eyes, two fluffy ears appeared on top of her head, while a swinging tail grew at her back.

When she saw these changes, Chu Wuyao was stunned and became a little dazed.

Only when she heard Cthulhu's excited voice did she wake up.

"Meow! Master, are you actually my long-lost sister?"
