In the middle of the night, a black figure with a gloomy aura suddenly landed in the middle of a small courtyard with a touch of cyan.

After the black figure settled, he looked at the man in Tsing Yi who was shrinking and hugging his right arm tightly, and said, "Let go, it's already here." ”

Zuo Qiusheng shrank his shoulders and carefully stepped on his feet back and forth, and after confirming that the ground under his feet was hard, he slowly opened his eyes, let go of the demon lord's arm with some grievances, lowered his head and said, "Your Majesty, let's ...... Can you ...... in the future? Don't fly around all the time, I ...... I'm most afraid of heights. ”

The Demon Lord was not annoyed, reached out and touched his head, and said lightly: "Didn't you say it yourself, you want to come to study the medicine residue." ”

"Hmm...... Yes. "That's exactly what happened.

Some blushed and scratched his head, and Zuo Qiusheng lowered his head again.

The Demon Lord glanced up at the courtyard and asked, "Here, can you find the medicine residue of that recipe?"

Zuo Qiusheng raised his head when he heard the question, stretched his neck and sniffed gently, and laughed: "Yes, this is it." ”

As he spoke, he took a gentle step forward following the taste, explaining as he walked: "The taste of each medicine is different, and it is even more different when mixed up." I smelled Miss Fengyin when I came during the day, and I knew it was here, but the Ghost King said that I couldn't mess around during the day, and I had to wait until the evening. ”

After walking a few steps, the pungent smell gradually became stronger. Zuo Qiusheng confirmed that the same fishy bitter smell as Miss Fengyin's body was emanating from under a small tree not far ahead.

With joy in his heart, he hurriedly took a step and ran over.

When he arrived under the tree, the fishy smell became even stronger, and Zuo Qiusheng hurriedly frowned and covered his nose.

Squatted down and took out a small shovel the size of a palm in his arms, Zuo Qiusheng covered his mouth and nose with one hand, and began to dig the soil with the other hand.

Zuo Qiusheng no longer covered his nose, picked up the scattered medicine residue one by one, and raised it under his nose to identify it by the smell.

"Dendrobium, Atractylodes, Atractylodes, Wheat Winter...... These are all good medicines. ”

After a while, Zuo Qiusheng shook his head a little puzzled, "Strange, why isn't it?If it's all tonics here, then how did Mr. Ji make Miss Fengyin look like that?"

Zuo Qiusheng has a characteristic, when he encounters a problem related to medical skills, he is fascinated, and the more difficult the question, the more confused he becomes, and he will never give up until he studies it thoroughly.

This Mr. Ji's prescription really stumped him, as soon as his stubbornness came up, his temper also came, and he was no longer patient to distinguish them one by one, so he simply knelt on the ground with a "plop" sound, and leaned down like a puppy to sniff at the large pile of medicine residue.

After discerning for a long time, a faint hint of sweet taste wafted into his nose, Zuo Qiusheng sniffed hard and closed his eyes, carefully searching his mind for the memories related to it.

Some fields flashed through his mind, and Zuo Qiusheng's eyes suddenly widened. As if he didn't dare to confirm this, he frowned, dug deeper into the soil, bent as low as he could to discern carefully, closed his eyes and sniffed for a while, until he was sure that it was correct, and then slowly straightened up and smiled contentedly.

I found this method myself!

Fortunately, although the taste is extremely light, it can't be dissipated due to the accumulation of time, and it is still noticed by myself.

Zuo Qiusheng shook his head and re-paved the mound, got up and patted the soil on his body, and became a little annoyed: "The doctor should have been benevolent and saved the wounded. But this Mr. Ji actually abused medical advice to abuse Miss Fengyin like this, he is really unworthy of being a doctor!"

Suddenly saw the small tree that was growing thin beside him, Zuo Qiusheng's eyes dimmed, he touched the trunk of the tree with sympathy, and sighed: "It's really hard for you, you can't grow up well because of these bitter things all day long, it must be very uncomfortable!"

A cool breeze blew, and a few weak branches at the top of the trunk were blown lightly, and Zuo Qiusheng nodded as if it was it, and hugged the trunk with pity before shaking his head and turning around.

But the moment he turned around, Zuo Qiusheng was suddenly stunned, the entire courtyard was empty, except for himself, there was not even a shadow.

So, where did the Demon Lord go?

Zuo Qiu was in a hurry all of a sudden, the demon lord is gone!

How could the Demon Lord be gone, how could it be gone? Just now, he was standing in the middle of the courtyard waiting for him!

If the Demon Lord is gone, how can he go out, what will he do! Looking up at the high courtyard wall, Zuo Qiusheng was so anxious that tears flowed out, he couldn't fly!

Afraid of alarming people, Zuo Qiusheng didn't dare to shout indiscriminately, so he could only search in the small courtyard little by little with a very aggrieved face, hoping to find the figure of the demon lord somewhere.

But after searching the entire courtyard, he didn't even let go of the horns, and Zuo Qiusheng finally found out in despair that the Demon Lord was really not in the courtyard.

Zuo Qiusheng slowly moved back to the center of the courtyard, and finally squatted on the ground and hugged his knees and cried. Strings of bean-sized tears rolled down from his eyes, but he was very careful not to make a sound, and only a little sobbing whimper overflowed from the tip of his nose, which was really aggrieved.

Suddenly, a cold wind blew, and the door of Miss Feng Yin's house in front of Zuo Qiusheng's eyes swayed gently with the wind, making an extremely dry "crunch" sound, which was particularly harsh and clear in the silent dark night.

Zuo Qiusheng was startled by this voice, and immediately stretched out his hand to wipe his eyes, and stiffened his back to look at it.

"Quack--squeak--", just as Zuo Qiusheng looked intently, the wooden door gently swung back with the breeze. Although he was taken aback again, this time Zuo Qiusheng was relieved, there were no demons and monsters, but the door was not closed tightly.

Zuo Qiusheng wiped his face again, sniffed, and then stood up and walked towards the door. The weather is so cold, and Miss Fengyin is not in good health, so she will definitely get cold if she doesn't close the door when she sleeps.

As soon as he walked to the door, Zuo Qiusheng keenly smelled a familiar breath, and he walked into the house and looked in without thinking about it for a moment of joy and surprise, sure enough, it was the Demon Lord!

Zuo Qiusheng's mood rose suddenly, and he walked to the back room with a smile, forgetting to close the door.

When Zuo Qiusheng approached, the Demon Lord was standing in front of a bed in the bedroom, quietly looking at the sleeping person on the bed. Zuo Qiusheng looked down and saw that it was Miss Fengyin.

Miss Fengyin was very asleep at this time, and she was unaware of the two people who came in the house, but even after she had fallen asleep so far, she still frowned lightly and looked very uneasy.

The Demon Lord sensed the movement behind him, slowly turned his head, looked at Zuo Qiusheng, and said, "Found it?"

Zuo Qiu was startled, looked at Miss Fengyin and said, "She?"

The Demon Monarch looked calm and said, "It's okay, she won't wake up." ”

"Oh. "It turned out to be a spell.

Only then did Zuo Qiusheng take his eyes off Miss Fengyin's face, looked at the Demon Monarch and said, "Well, I found it." ”

As he spoke, he took out a tied silk handkerchief from his arms, untied it in his hand, revealed the black soil, raised it forward to the Demon Lord's eyes, and said, "That's it, you smell it." ”

The Demon Lord glanced at the soil, and without saying anything, he looked at Zuo Qiusheng again.

Zuo Qiusheng took his hand back, tied the silk handkerchief and carefully put it back in his arms, before he said: "This soil has the smell of Tianhe grass, presumably it is dried and ground into powder and mixed into medicine." ”

"Crane grass?"

"Well," Zuo Qiusheng moved his gaze to Miss Fengyin's face and said, "The Crane Grass itself is not very toxic, but it will make people weak and weak. But it is recorded in ancient books that there is a kind of insect that feeds on it, and that kind of insect is called the hidden ruler. ”

Zuo Qiusheng looked at Miss Fengyin's eyes with a thick unbearability, pursed his lips and continued: "The hidden ruler is an ancient poisonous insect, they feed on the crane grass and live on the sojourn, once they enter the body of the living being, they will secrete a kind of mucus to build a nest, and this mucus will block the blood veins and corrode the meridians step by step, and the sojourners will eventually die due to the burst of the meridians and become the 'ruler nest'. Many creatures have died at its hands before, so it was exterminated a long time ago, but I didn't expect to find traces of it here. ”

The Demon Lord's gaze cooled, and there was a hint of surprise in his tone: "Into the body?"

Zuo Qiusheng nodded and sighed, "That's right, there should be a hidden ruler worm in her body." ”

The Demon Lord was silent, looking at Feng Yin and frowning tightly.

"But since she is still alive, it means that the worm should have been dealt with, not enough to kill people, and that Mr. Ji has not completely lost his conscience. ”

The Demon Lord took a step forward, stretched out his hand to smooth Feng Yin's eyebrows, and said, "This child shouldn't have lived like this. ”

Zuo Qiusheng heard the pity in the Demon Lord's words, and comforted: "When I checked Miss Fengyin's pulse that day, I didn't notice that her illness was so abnormal, it should be that the worm starved to death after she stopped taking the medicine, and it stands to reason that it should have been excreted from the body, so you don't have to worry too much." ”

The Demon Lord withdrew his hand and said nothing more.

Zuo Qiusheng suddenly became a little curious, took a step forward and walked to the side of the Demon Monarch, leaned over to the side, opened his eyes wide, and asked in a low voice, "Your Excellency, do you like Miss Fengyin to help her like this?"

The Demon Lord's eyes were slightly gloomy, and he turned his face to look at him, and said, "Why do you think so?"

Zuo Qiusheng scratched his head, pouted and muttered in a low voice, "The Ghost King said that you have taken a fancy to Miss Feng Yin." But...... I used to ...... I thought you liked Sister Pipit, and many people said that Sister Pipit would become the queen of demons. ”

The Demon Lord glanced at Zuo Qiusheng lightly, turned around and walked towards the outside of the house, and said, "If I didn't say it, you don't have to believe it." ”

Zuo Qiusheng hurriedly followed his pace and asked again, "What's that...... Do you like Miss Windyin, the Ghost King said that you would take her back to the Demon Realm. ”

The Demon Lord stopped, turned his head to look at Zuo Qiusheng, who almost bumped into him, and said, "You were also brought back to the Demon Realm by me, don't you remember?"

"I, that'...... That's ......" Zuo Qiusheng didn't know what to say for a while, frowned in distress and closed his mouth.

Seeing that he didn't ask any more, the Demon Lord turned around and walked out the door.

Zuo Qiusheng scratched his head with some annoyance, hurriedly chased after him, and didn't forget to turn around and gently close the door after going out.
