The space is full of supplies, and the little milk bag can't be used up.

"The doctor... came, but... it was useless." Song Nanyao uttered a few more words with difficulty. He knew very well that even if the doctor came, it would be useless.

At this time, Doctor Li was sorting out medicinal materials at home when he suddenly heard a hurried knock on the door. He opened the door and saw that it was Li Kangze. Li Kangze said anxiously, "Doctor Li, please come with me!"

"Slow down, slow down. My old bones can't run anymore!" Doctor Li waved his hands quickly.

"Human lives are at stake! It will be too late if we delay!" Li Kangze anxiously dragged Doctor Li out.

The two of them trotted along and soon arrived at the courtyard. After entering the inner room, Doctor Li saw a little boy lying on the bed with his face as pale as paper, holding his chest tightly with both hands, looking very painful.

"Stretch out your hand and let me see it." Doctor Li said solemnly.

Song Nanyao used up all his strength before slowly extending his other hand.

Doctor Li carefully felt the patient's pulse, but his frown deepened. After a long time, he still couldn't figure out what was going on.

This pulse is really strange, it is neither like a common disease nor a sign of physical weakness. It is rare for someone to survive with such a weak pulse.

"Doctor Li, what happened?" Ye asked anxiously.

Doctor Li sighed and shook his head helplessly: "I can't cure this disease. I have never seen anyone alive with such a weak pulse. It's really strange." He paused, then continued: "Maybe you can go to the capital to find a more famous doctor and try. Maybe they have a way." After that, he picked up his medicine box and prepared to leave.

"I understand. I'll bring Brother Nannan in..." Li Youran didn't finish his words, but Ye and Li Kangze understood.

Ye took out some silver and gave it to Doctor Li, and then Doctor Li left.

"Ze'er, come in with Ran'er!" Ye looked at her daughter worriedly, her tone full of concern and uneasiness.

"Okay, Mom." Li Kangze responded softly. He knew very well how much his mother cared about his sister.

Li Youran carefully led Song Nanyao and Li Kangze into the space.

The moment she stepped into the space, she moved Song Nanyao into the purification pool without hesitation.

Yumian happened to catch a glimpse of the young master walking in, and her eyes immediately fell on the little boy in the purification pool.

He was as pale as paper, lying weakly in the purification pool, with one hand tightly covering his chest.

"Young master, what happened?" Yumian was full of suspicion and asked quickly.

"I'm not too sure. Brother Nan Yao suddenly became like this. Yumian, you know more and maybe you can help see what happened to him." Li Youran was anxious and hoped that Yumian could find a solution to the problem.

Yumian walked forward with light steps, staring intently at Song Nanyao's heart.

The more he looked at it, the more strange it seemed. "He...he is definitely not a mortal."

Li Youran and Li Kangze were both stunned after hearing this. What? Not a mortal? Could it be a ghost?

"Yumian, please explain it to me clearly!" Li Youran was frightened by Yumian's words.

"Yes, he is really not an ordinary person, and he should have had a sword with him, but now the sword should have been lost." Yumian told everything she knew.

After hearing what Yumian said, Song Nanyao was stunned. How could this little fox know all these things? Could it be that it knew some other inside information?

Because his chest was hurting so much at the moment, he was temporarily unable to speak, and the purification pool could only relieve his pain slightly.

"Then...if we can't find the sword, what can we do to save him?" After hearing the news that the sword was lost, Li Youran's tears, which she had just held back with great difficulty, burst out from her eyes again like a flood breaking through a dam.

Is this handsome boy going to die like this? She really can't accept this fact.

Li Kangze felt heartbroken when he saw his sister crying.

He reached out his hand and gently stroked Li Youran's hair, and said softly, "Ran'er is so outstanding, he will be safe and sound. Don't cry anymore."

Li Youran felt a little comforted after hearing his brother's words.

She recalled her ability to sign contracts with those beasts and was convinced that she would be able to help him.

While she was thinking, Yumian beside her said in a heavy voice: "Young Master, you have a way to save him, you can use your blood."

Li Youran nodded without hesitation, indicating that she was willing to try.

She bit her fingertips and blood oozed out. Although the pain was unbearable, she clenched her teeth and endured the pain.

Then, she stretched her bleeding finger to Song Nanyao's lips. At first, Song Nanyao was a little resistant, but when he saw the little girl's tear-stained face and red and swollen eyes, his heart softened and he gently sucked a mouthful of blood.

Li Youran endured the stinging pain and then put his hand into the purification pool.

The wound on her hand healed quickly, as if she had never been injured.

At this moment, balls of pink light bloomed around Song Nanyao.

These lights were like warm streams, slowly flowing into Song Nanyao's body.

In an instant, the unbearable pain completely disappeared.

The lotus flower in the center of Li Youran’s forehead appeared faintly, and then disappeared.

Li Youran felt a splitting headache, as if countless steel needles were stirring in her brain, making it almost unbearable for her.

Her vision gradually became blurred, her body became extremely heavy, and finally, as if she had lost all her strength, she collapsed to the ground.

Li Kangze, who was standing by, witnessed all this and was horrified.

He rushed forward without hesitation, supported his sister who was about to fall to the ground, and called out anxiously: "Sister! Sister! What's wrong with you? Wake up!" His voice was full of panic and anxiety, and his face was as pale as paper.

However, in response to Li Kangze's calls, Li Youran did not respond, his eyes were tightly closed, and he seemed to have fallen into a coma.

Li Kangze's heart was instantly filled with fear. He hugged his sister tightly, fearing that she would disappear if he let go.

At this moment, a gentle voice came into his ears. "The little master is just too tired. Take her to the cabin to rest for a while. She will wake up soon." It was Yumian who spoke. It knew that the little master would be exhausted and even collapse every time she used her blood to save people.

Therefore, it was well thought out when it provided this method to its little master.

After hearing Yumian's explanation, Li Kangze finally felt relieved.

He let out a long sigh, quickly picked up his sister, and walked hurriedly towards the cabin.

Every step seemed so cautious, as if he was holding the most precious treasure in the world.

On the other side, Song Nanyao felt his body suddenly relaxed a lot, and the original pain seemed to disappear in an instant.

He looked at Li Youran with gratitude, but found that she had fainted on the ground.

Looking at her haggard face, Song Nanyao couldn't help but feel an indescribable feeling of heartache and guilt.

His heart seemed to be plucked hard by an invisible hand, causing unbearable pain.
