In this life, he has supreme medical skills, and he has the ability to defy the sky, even if the sky does not allow him, he must go against the sky.

Mu Xiyun has been weak since he was a child and is very prone to illness, and the head of the family cares for him, and he is never stingy with all kinds of precious medicinal materials.

When Mu Xiyun was six years old, it was detected that he had a dark spiritual vein, which was called a great misfortune for hundreds of years.

According to the scriptures, a person with a dark vein is born weak and sickly, and the dark vein will devour the lifeline and become angry, unless the spirit vein is sealed, or the spirit vein is awakened, it will definitely die.

In the entire Yuncang Kingdom, I have never heard of a person with a dark spiritual vein who can live past the age of fifteen, because no one knows the method of awakening and sealing at all.

Since then, the head of the family has regarded Mu Xiyun as a treasure, and he is reluctant to fight or scold, for fear that he will hurt him if he is not careful.

Just two years ago, his father Mu Tian heard the news of "the existence of a strange grass 'Sealing Spirit Grass' that seals the spiritual veins on Heiyun Mountain".

In order to seal the dark spiritual veins on Mu Xiyun's body and prevent his lifeline from continuing to lose anger, but he didn't want to make too much noise about it, so he went to Heiyun Mountain alone to find this strange grass, but he was ambushed by a group of black-clothed people halfway and was seriously injured.

Mu Xiyun was reminiscing, there were bursts of footsteps outside the door, and he looked at the door along the sound, his heart trembled suddenly, his eyes were stunned, and his face suddenly showed the joy of reuniting after a long absence.

"Squeak!" The sound of the door opening was particularly clear, and a slender figure slowly walked in from outside the door, and in an instant, the four eyes met.

"Ah, brother, you're awake!" The woman saw Mu Xiyun sitting on the bed, her face was full of surprise, she exclaimed in surprise and quickened her pace.

Soon, a beautiful girl appeared in front of Mu Xiyun. She wore a light blue dress with a light blue upper body and a cloud-white waist, and a small pendant around the hem of the dress shimmered with a slight red glow. The small face is delicate and delicate, the light red lips are delicate, the smile is gentle and moving, and the black hair hangs down to the waist, which adds a little more agility to his already slender figure.

Mu Xiyun looked at the girl who was close at hand, her eyes were slightly distracted, as if all this seemed a little unreal.

Looking at her eyes that were as clear as spring water, and the deep worry that filled them, Mu Xiyun only felt a warm current rushing into his heart, because this was his sister Mu Xin'er, who had been the best to him since he was a child, and was also his closest sister.

Mu Xin'er walked quickly to Mu Xiyun's bed and sat down, the back of her warm jade hand was attached to Mu Xiyun's forehead, and she felt that Mu Xiyun's body temperature had dropped a lot, and the worry on her face eased a little.

But Mu Xin'er didn't let go of her heart because of this, and the hand she just put down directly grabbed Mu Xiyun, then bent down slightly, and gently stroked the back of her head with her other hand, and then gently pressed her forehead against the other party's forehead, and felt her body temperature again.

Feeling Mu Xin'er's warm and smooth skin, as well as the girl's exclusive charming fragrance, the corners of Mu Xiyun's mouth twitched slightly, and a warm current rose silently in her heart.

If there is anyone in this world who is the best and gentlest to him, then there must be no need to think about it, it must be Mu Xin'er.

After a while, Mu Xin'er's forehead moved away, and the tension and worry on her face suddenly dissipated.

"Sister Xin'er, why are you here?" Mu Xiyun smiled as she struggled to hold up her weak body and look in good spirits.

"Thankfully, the temperature is almost back to normal. Mu Xin'er didn't answer the question immediately, but breathed a sigh of relief, fortunately.

Then, Mu Xin'er took Mu Xiyun's hand and slowly put it down, let him lie flat on the bed, and covered him with a quilt.

At this time, looking at each other, Mu Xin'er held Mu Xiyun's hand tightly, and said with some fear: "The day before yesterday, you suffered from a cold, and then inexplicably launched a high fever, and soon after you fainted, I went to invite Master Chen to see a doctor for you, but Master Chen said that you have no power to return to heaven, do you know..."

The more Mu Xin'er spoke, the more excited she became, and in the end she was so choked that she couldn't speak, and unconsciously, her eyes were slightly red, the corners of her eyes gradually moistened, and even her delicate body trembled.

"Did you know that my father and I were worried about you. Mu Xin'er finally couldn't help crying, her voice was obviously a little hoarse, and there was a lost and recovered emotion in her sobbing, which made people feel sour when they heard it.

"It's great that you're awake now, and I know that you're not going to be so prone to accidents, brother. Mu Xin'er quickly wiped away the two lines of tears on her face, smiled at Mu Xiyun, and tried to restrain her emotions.

Mu Xin'er calmed down her excitement a little, her clear eyes looked at Mu Xiyun, patted her chest a few times, and smiled with a big sister attitude: "Don't worry, my sister will always be with you, don't be afraid!"

Looking at Mu Xin'er in front of her, her eyes that were still a little hazy, and the tears that had not yet dried out, Mu Xiyun only felt a deep sense of self-blame stinging her heart.

"I'm sorry for worrying my sister and father!" Mu Xiyun pursed her lips and said softly.

When Mu Xin'er heard this, she instantly stopped choking, and tried her best to prevent the tears from flowing again, for fear that Mu Xiyun would blame herself for this, and hurriedly said: "It's okay, as long as you're okay, my father and I will be very relieved." ”

"You rest obediently, I'll go tell Daddy first, Daddy will be very happy if he knows that you are awake. ”

Mu Xin'er seemed to have thought of something, said something to Mu Xiyun, and then left the room.

"With these tears you shed for me, I'm afraid I'll never be able to pay them back, since I'm reborn again, then use my life to protect you, make you happy forever, and never let anyone hurt you, unless I die. Looking at Mu Xin'er's back as she left in a hurry, Mu Xiyun thought in her heart.

How good Mu Xin'er is to him, only Mu Xiyun himself knows.

Countless times when I was sick, I always accompanied the person by my side.

Countless times by others ridiculed and snubbed, people who stand in the way.

Countless times secretly gave him various resources divided by the family, and if he didn't accept it, he would get angry......

I'm lucky to have such a sister, I'm glad that I'm still alive...
