I woke up to find myself as the villain's older sister.

"Then do you know what's wrong with me?"

"Although I am skilled in medicine, I cannot give a diagnosis just by looking at someone. So, miss, could you tell me what happened?"

“Hmm…” Yun Qingyi pondered for a moment and then told him about a piece of her lost memory.

"At that time, not only was my sister's expression strange, but her whole aura also changed dramatically. Her eyes turned crimson in an instant, and she murmured something, but it was impossible to tell what she was saying."

Yun Qingrou recounted the details, revealing that she was the only one who was constantly watching over Yun Qingyi at the time.

"Red Eyes, without any warning, her personality changed drastically, and she inexplicably lost a piece of her memory..." the boy murmured, his expression somewhat strange.

The boy's attitude toward Yun Qingyi afterwards was completely different from his previous fawning and obsequious demeanor.

He knelt down directly before Yun Qingyi, his expression respectful and his gaze firm: "There is indeed a case in my family's ancestral books that matches this description."

"But... I'm sorry I can't tell you the reason right now, Miss."

After saying that, he continued to kneel on the ground, adopting an attitude of resignation.

The hot-tempered elder couldn't resist kicking him again.

"You! You, you, you! What the hell! You're the one who came to heal people, and you're the one who didn't! Are you here to make fun of us? Do you really think I got my Nascent Soul stage cultivation by cheating?"

"calm down!"

The three elders stopped him again.

In an instant, a sword was pressed against the boy's throat.

“I’m not as patient as my older sister.”

Yun Qingyi did not stop him, and looked at the boy kneeling on the ground with a leisurely air.

"I'm sorry to have to obey."

The longsword sliced ​​across his throat, and beads of blood gushed out.

"explain."

The boy stubbornly held his head high, remaining silent.

Just as Yun Qingrou was about to end him with a single sword strike,

"Arou."

……

Yun Qingrou glanced coldly at the boy and sheathed her longsword.

Okay, now it's her who's feeling aggrieved.

"When can you tell me?" Yun Qingyi looked at him with a languid expression, a half-smile on her face.

"Once Miss reaches the Nascent Soul stage, I will tell her everything I know."

Yun Qingyi raised an eyebrow. "Then how am I supposed to know if what you're saying is true or false, and how am I supposed to find you?"

"I will acknowledge Miss as my master."

Huh? What??

Seeing the astonished looks on everyone's faces, the boy realized it was a misunderstanding and said seriously, "I am not human."

……

"There's no need to be so self-deprecating."

juvenile:……

“I am not human. I am a spiritual herb that my master picked. My master said that I was blessed by the heavens and that the essence of heaven and earth was rushing to let me absorb it. Before he could use me as medicine, I transformed into human form. My master was furious. He couldn’t bear to kill me, so he raised me, took me as his disciple, and taught me how to make medicine.”

"Spirit beasts can form contracts with their masters, and so can I."

The boy looked at Yun Qingyi, whose expression was unclear, and explained with a serious face.

……

"your name."

My name is Cao Changle.

"My name was given to me by my master. My surname is Cao, which is a homonym for grass. He hoped that I would live a long and happy life."

“A very good name. From now on, I will be your master.”

Cao Changle stood up with joy, and with a thought, a contract array appeared beneath his feet.

Once the others could see the patterns of the great formation clearly, they left the formation with peace of mind, leaving only the young man and Yun Qingyi behind.

"Then, Master, let's begin the contract ceremony."

Cao Changle forced a drop of blood from her fingertip, which fell into the great formation. Yun Qingyi nodded and hummed in agreement, also forcing out a drop of blood.

The blood droplets merged in pairs, eventually transforming into a long blood streak that spread across the patterns of the great formation.

This contract is called the Contract of Life and Death. When the servant dies, the master lives; when the master dies, the servant dies. Their souls will follow each other for eternity.

As the contract was being executed, Yun Qingyi also had images of the contract in her mind.

This contract... almost entirely benefits her, which makes Yun Qingyi feel somewhat complicated.

Never mind, since he trusts me, I will protect him for life.

……

After a long time, the formation gradually faded, and a small mark appeared a little above Yun Qingyi's brow, resembling neither a flower nor a blade of grass.

Yun Qingyi wasn't bad-looking, so she didn't bother to hide it.

"Changle."

"Master, I am here."

……

There's no need to call her "master" all the time. She was just having a fit of chuunibyou (middle school syndrome) moment, and it sounds rather embarrassing now.

"You...you don't need to call me master anymore, just call me Qingyi."

Cao Changle blushed slightly and stammered, "Qing...Qingyi."

Yun Qingyi patted his shoulder and smiled, "I didn't expect you to be so shy. It's okay, you'll get used to it."

Yun Qingrou watched their interaction, picked up the sword in her hand, picked it up, put it down, picked it up again, and put it down again.

In the end, she decided to let it go. Oh well, he was just her older sister's little dog, and she wouldn't stoop to his level.

"By the way, you must have lived for a long time, right? What is your bone age now?" Yun Qingyi asked Cao Changle, remembering something.

Cao Changle scratched his head sheepishly: "I've been a grass for quite a long time, but I've only been a human for fifteen years, so my bone age is only fifteen years."

Yun Qingyi nodded. At fifteen years old, she had reached the Great Perfection of Qi Refining. Although she was already exceptionally talented among ordinary people, she was nothing special in the Xuanmiao Sect, where geniuses gathered.

If it were a normal recruitment ceremony, entering the inner sect would be more than enough, but now that they are recruiting personal disciples, Cao Changle's hopes are very slim.

"It's a pity, you're only at the Qi Refining stage." Yun Qingyi shook her head regretfully at Cao Changle.

"Hmm? What's a pity? Does Qingyi not like me being in the Qi Refining stage? Then what stage does Qingyi like? I can be in the Foundation Establishment stage, Golden Core stage, or Nascent Soul stage, but nothing higher."

Although Cao Changle couldn't understand what Yun Qingyi was saying, he still wanted to fulfill her request.

……

"What did you say?"

Upon hearing this, Yun Qingyi was shocked. Even when he said he wasn't human, he hadn't given her this much of a shock.

The four elders were stunned at first, then seemed to breathe a sigh of relief as if they had been comforted.

The hot-tempered elder laughed loudly, looking up at the sky.

"I knew I'd fallen for the trick of a mere Qi Refining stage cultivator."

Yun Qingrou remained expressionless. She pursed her lips, thinking, "Damn it, this makes it even harder to kill him."

"I said I could be at the Qi Refining stage, Foundation Establishment stage, Golden Core stage, or Nascent Soul stage. What's wrong, Qingyi?"

Cao Changle looked at everyone, puzzled, and asked in a weak voice.

After a while, Yun Qingyi calmed down.

Ask that crucial question.

"So your current level is actually?"

"I am now in the mid-stage of the Nascent Soul realm."

Although it was the expected result, I still couldn't help but gasp.

What's wrong with you? Is it better to be a blade of grass than a human?

Actually, Yun Qingyi was just making a small complaint. If she really treated it like grass, she might have fed it to pigs somewhere!

Cao Changle, this blade of grass imbued with countless blessings, is someone to be admired from afar, not to be coveted.

"Then how did you manage to lower your cultivation level to the Qi Refining stage without being detected by people with higher cultivation levels than you?"

Cao Changle smiled gently and said, "Is that what Qingyi is concerned about? Actually, Qingyi can do it now too. It's one of my own talents, and I can share it with Qingyi."

At this moment, Yun Qingrou frowned. This person was useful to her elder sister, so she couldn't kill him.
