I became a villain in a book. Why did the heroine turn evil first?

She looked at her senior sister with a smile and spoke.

"Senior Sister, no matter what you become in the future or what bloodline you have, I will always stand by your side."

That day, it was the first time that her senior sister cried since she had known her.

The senior sister leaned in her arms, crying like a child, and no matter how hard she tried to comfort her, she still didn't stop.

In the past, Senior Sister always showed her gentle and reliable side in front of her. Now that she suddenly saw Senior Sister's vulnerability, she felt that her love for her became even deeper.

So she secretly decided in her heart that no matter what happened in the future, she would never let go of her senior sister's hand.

After coming out of the Shura battlefield, the two acted as if nothing had happened, but in order to prevent her senior sister's Shura bloodline from awakening again, she still found ways to study many things.

But fortunately, in the next few years, Senior Sister's bloodline was very stable and there were no sudden outbreaks.

The elder sister also told her everything about how she met the great Shura in the sword immortal inheritance and received his inheritance. And just like before, she taught her how to practice the Yuandan system step by step.

When they were promoted to the Spiritual Immortal Realm, the Immortal Palace threatened the peace between the two realms and forced the Demon Realm to open up the access to the Demon Abyss. They demanded that the Demon Lord agree that the next time the Demon Abyss was opened, the cultivators of the Immortal Palace would be allowed to enter as well.

That time, the Demon Abyss was open for a full ten years, and they also stayed in the Demon Abyss for a full ten years.

The concentration of spiritual energy in the Demon Abyss is very high, and it is very compatible with the Yuandan cultivation system. In the past ten years, the two of them were even just one step away from breaking through to the Chengxian Realm.

After coming out of the Demon Abyss, they returned to Jiuzhou Immortal Palace, and the senior sister's Shura bloodline also completely subsided.

Just when they thought that the Shura bloodline would be hidden, an accident happened.

When the senior sister broke through to the sixth level of the Immortal Realm, the Shura bloodline erupted again, and it happened in full view of everyone in the Jiuzhou Immortal Mansion. This time, it was impossible to hide it even if she wanted to.

Overnight, my senior sister went from being a favored girl who had the potential to ascend to the immortal realm a hundred years ago, to a descendant of the Shura clan who was hated and wanted to be killed by everyone in the immortal cultivation world.

Not only did several palace masters lock up the senior sister, they also called in the medical immortal Yan He to study the senior sister's Shura bloodline.

Qian Liao of Jiuzhou Immortal Mansion also told her that a talent like her senior sister's would only appear once in tens of thousands of years, and they would not give up on her. They only brought the Medical Immortal here to restrain her bloodline so that she could practice normally in the future.

She was half-believing and half-doubting Qian Liao's words. However, with her current strength, she really had no way to save people from the hands of the palace masters.

Therefore, she could only practice desperately and secretly look for opportunities to at least visit her senior sister and see how she was doing now.

She didn't have to wait too long for this opportunity. A year later, the five palace masters went out at the same time to discuss things with the Demon Lord.

After seeing that all five palace masters had left, Su Yunyao quietly went to the place where her senior sister was imprisoned.

But when she saw her senior sister again, Su Yunyao felt that the blood in her body seemed to have been boiled by the anger in her body.

The white clothes on the senior sister's body had long been stained with blood, and there were many wounds of varying sizes on her body. With the strength of the senior sister's body, she could not recover from them. This was enough to prove how much suffering the senior sister had endured in the past year.

After rescuing her sister, she found Yan Helai's residence and directly cut the tendons of Yan Helai's hands and feet, destroying his cultivation. Just when she was about to take Yan Helai away, two Jinling elders appeared to stop her.

That night, two Gold-rank elders and more than forty Silver-rank elders died in Jiuzhou Immortal Palace, and the medical immortal who was a guest there disappeared.

As for Yan Helai, he was dragged for tens of thousands of miles by Su Yunyao and thrown directly into the nest of a group of Zhenyuan realm monsters.

Although Yan Helai's cultivation in the fairyland was destroyed, his body was still strong. He screamed for several hours before finally dying after being eaten by the Zhenyuan realm monster.

Su Yunyao left with her senior sister only after Yan Helai was eaten up.

Fortunately, she was lucky. She thought she would have to live a life of escape with her senior sister, but she unexpectedly discovered a small world of her own. At this time, the way of talisman formation she learned from her senior sister came in handy.

After some research, she finally succeeded in cracking the entrance to the small world. Hiding in this small world, she no longer had to worry about being found by the people in the Immortal Palace.

However, Yan Helai had poisoned her senior sister with several kinds of poisons. Although she had already extracted the antidotes to these poisons from Yan Helai, it would take at least a few years to completely eliminate them.

As the two of them spent more and more time alone, the feelings in her heart became more and more uncontrollable. One day, she finally confessed her love to her senior sister regardless of the consequences.

However, to her surprise, although the senior sister was shocked at first, she did not show any resistance. She could even feel a hint of joy in the senior sister's eyes.

However, in the end, the senior sister still rejected her. However, the senior sister was not very good at lying, and she easily understood that the senior sister's rejection was not because she didn't like her, but because the senior sister's current identity would bring her endless troubles.

Would she care about this? Of course not.

So, in order to express her determination, that night, while her senior sister was still weak, she pushed her down on the bed.

Now that the matter was settled, the senior sister had no reason to push her away.

A few years later, an uninvited guest suddenly broke into this small world. That person was Huo Tutu, the current Demon Lord of the Demon Realm.

Huo Tutu was murdered by five masters of the Immortal Palace. He was poisoned and his cultivation level plummeted. He accidentally entered this small world.

Having also been harmed by the Immortal Palace, the senior sister felt sympathy for Huo Tu Tu. After accidentally discovering that Shura blood could restrain the poison, she spared no effort to help Huo Tu Tu recover his cultivation.

Because of this encounter, she became friends with the Demon Lord Huo Tu Tu. Finally, with the help of the power of the Demon Realm, the two of them finally killed the five palace masters.

At this point, all the forces that could threaten them were finally eliminated. After living in peace for decades, the two of them finally faced their own tribulation of ascension.

With their talents, they passed the heavenly tribulation smoothly. After they created the last three source blood treasures, they opened the ascension channel with the blessings of their friends.

However, the accident came very suddenly. After the passage was opened, an immortal soldier came down from the passage first, pointing his spear directly at the senior sister.

After the two fought hard, they were still no match for the immortal weapon. In the end, the senior sister used up all her spiritual energy and sent her into the ascension channel, but the senior sister herself died at the hands of the immortal weapon.
