A mortal cultivating immortality can nurture spirit beasts.

Lin He opened the door and, sure enough, saw Xiao Mei, her face streaked with tears. Her eyes were red and swollen, and she anxiously tugged at Lin He's sleeve, pleading...

"Senior Lin, my young lady..."

"Xiaomei, don't rush, tell me slowly, what happened to your young lady?"

"Miss...Miss is sick!"

In fact, Lin He already knew the situation, but he still had to put on an act, so he immediately had Xiao Mei lead the way to Xin Ruyin's boudoir.

Although Xin Ruyin was just a rogue cultivator, women generally pay attention to their appearance. Her boudoir was clean and tidy, and had a refreshing fragrance. Lin He nodded to himself as he looked at her. He went to the bedside and carefully examined the unconscious Xin Ruyin.

At this moment, she was burning up, with heat rising from her body as if she were on fire. Lin He tried to inject a trace of spiritual power, but it not only had no effect, but it was like adding fuel to the fire, making the heat even stronger. Lin He knew something was wrong, so he immediately stopped injecting spiritual power, which prevented Xin Ruyin from dying on the spot.

Lin He broke out in a cold sweat, thinking to himself that the Dragon Roar Body was indeed strange and difficult to deal with.

Xiao Mei, who didn't understand any of this, quickly asked, "Senior Lin, could you use your magic to help my young lady suppress her illness?"

Lin He shook his head and patiently explained, "Your young lady has broken through in her cultivation technique, did you know?"

Xiao Mei was taken aback upon hearing this, and only then did she belatedly use her Heavenly Eye Technique to check. Sure enough, she discovered that Xin Ruyin's cultivation had broken through to the eighth level of Qi Refining. She couldn't help but ask, "Isn't a breakthrough in cultivation a good thing? Why are you sick?"

"It's a good thing for others, but not for your young lady," Lin He continued to explain. "Are you aware that your young lady possesses the Dragon Roar Physique?"

Seeing Xiaomei nod, Lin He continued, "This Dragon Roar Body is very special. As long as the cultivation method breaks through, it is easy to trigger the Dragon Roar Qi in the body, which is the so-called excess of Yang Qi and difficulty in controlling Yin Qi, resulting in an imbalance of Yin and Yang. If this continues for a long time, the entire body will probably collapse. Such people generally do not live for long."

Upon hearing this, Xiaomei panicked and immediately knelt down. "Senior Lin, please save my young lady! I'll do anything you ask, as long as you save her..."

Lin He quickly helped her up. "Xiao Mei, I cultivate yang energy. When I injected my energy just now, it actually amplified the dragon's roar energy within her, so I stopped immediately. I only know two ways to save your young lady."

"First, find a cultivator who practices Yin-cold magic to inject magic into your young lady every once in a while to suppress the dragon roar energy in her body. This cultivator's cultivation level cannot be low. Judging from your young lady's current situation, even a Foundation Establishment cultivator would probably have a hard time doing this. It would be best if he were a Core Formation cultivator."

Upon hearing that it would require a Core Formation stage cultivator to inject icy magical power to suppress it every so often, Xiao Mei shook her head with a wry smile. This method was simply impractical, and she rejected it without even thinking about it.

Seeing Xiaomei shake her head, Lin He began to explain the second method, "The second method is to use the power of spiritual herbs. However, judging from your young lady's condition, spiritual herbs that are a few hundred years old may not be very effective. At least a thousand-year-old spiritual herb is needed, and it must be a thousand-year-old spiritual herb with cold medicinal properties."

Hearing about the second method, Xiaomei was not surprised. She quickly said, "My young lady has also thought of the method that Senior Lin came up with, and she has even obtained the prescription. However, she is still missing a thousand-year-old spiritual herb as a medicinal guide, so she has been unable to implement it."

Lin He looked at Xiao Mei, who was a little puzzled and was about to ask a question when Lin He suddenly took out something from his storage bag. It was the Thousand-Year Cold Star Grass that he had obtained from the forbidden area trial.

"Xiaomei, look what this is?"

"This...this is..."

Xiao Mei's tongue slurred, and she stammered. This Thousand-Year Cold Star Herb was extremely cold in nature; the moment Lin He took it out, the entire room seemed to grow colder. Seeing this, Xiao Mei couldn't help but swallow hard. "Senior Lin, this... this could be... a thousand-year-old spiritual herb?"

"That's right," Lin He nodded. "This spiritual herb is called Cold Star Grass. It has extremely cold medicinal properties and is over a thousand years old. I originally wanted to use it to refine pills, but since your young lady urgently needs this herb, then I'll let her use it."

Xiao Mei was dumbfounded. Even if she had a slow reaction time, she knew how precious the thousand-year-old spiritual medicine was. It was something that many cultivators would fight tooth and nail for, yet Lin He had actually taken it out on his own initiative.

"Senior Lin, this thousand-year-old spiritual herb is so precious... how can this be?"

Xiao Mei was filled with mixed feelings of joy and worry. On one hand, she was overjoyed because her mistress was saved, but on the other hand, she was extremely worried. The thousand-year-old spiritual herb was too precious, and she owed such a huge favor that she didn't know how to repay it.

"Saving lives is urgent, and your young lady's condition can't wait much longer, Xiaomei. Do you really want to watch your young lady suffer and die?"

At this point, Lin He's tone became stern, and Xiao Mei could only nod and say, "Senior Lin, I will never forget your great kindness. Miss has already bought the other auxiliary medicinal materials, and now that we have this thousand-year-old spiritual herb as a medicinal guide, everything is ready. I will go and decoct the medicine now."

After Xiaomei left, Lin He walked to the bedside. He was about to take her pulse to check her condition when Xin Ruyin suddenly broke out in a cold sweat, and pain appeared on her face. She was clearly suffering inhuman torment.

It's unclear where she got the strength, but she grabbed Lin He's hand as if she had grasped a lifeline, her nails digging deep into Lin He's flesh.

Lin He was somewhat helpless. He could only endure being held so tightly by Xin Ruyin. However, Xin Ruyin seemed to think that this was not enough. Just as she was grimacing in pain, she suddenly grabbed Lin He's right hand and bit down hard, as if that would make her feel better.

Fortunately, he had amazing willpower and managed to hold back. He let her grab and bite him, and after who knows how long, Xiaomei finally came in with a bowl of medicine.

"Miss, it's time to get up and take your medicine!"

As soon as they entered, they saw Lin He's miserable state. This man, who had killed Xu Yan and his group without batting an eye, was now being forced to retreat in the face of Xin Ruyin's sharp teeth.

Perhaps it was Xiaomei's voice that woke her up, for Xin Ruyin slowly awoke. She opened her eyes to a handsome face and a comical expression of pain in someone's face. She immediately understood what was happening, quickly loosening her grip on her fingers and teeth, her face flushed red, and she apologized with a look of shame.

"I'm sorry, senior, I... I bit you!"

Seeing that she had let go, Lin He immediately breathed a sigh of relief. He tried his best to maintain his composure and waved his hand, saying, "How could I, a dignified Foundation Establishment cultivator, be bitten? Cough cough... Miss Ruyin, your teeth are far more powerful than top-tier magic weapons."

Upon hearing this, Xin Ruyin's face turned as red as an apple, and she was so ashamed that she wanted to hide away.

"Miss, it's time to take your medicine!"

Fortunately, Xiaomei hadn't forgotten the important matter, but Xin Ruyin asked with some suspicion,

"Xiaomei, what kind of medicine is this?"

"This is..." Xiaomei naturally didn't hide anything and recounted what had happened. When the thousand-year-old spiritual herb was mentioned, Xin Ruyin fell silent for a while for some reason. Then she suddenly said...

"Xiaomei, you can go out now. I want to talk to Senior Lin alone."
