Nalan Lingyun lives in the most secluded small courtyard of Tianchi Medical Village, and there is an alchemy room and a residence in the courtyard.

At this time, Nalan Lingyun was refining the pill, however, she couldn't calm down.

During the day, the words that Sima Jiu said to her have been haunting her heart.

Her father has been gone for a long time, and the father she remembers has not done anything strange.

After my father left, he didn't leave anything special behind.

The only thing special is the golden koi in the pond in the small courtyard.

Strange to say, the koi was sent by my father when he left, but after so many years, the koi has not changed much.

It seems that birth, old age, sickness and death have nothing to do with it.

In the pond, the golden koi swims with its tail wagging and its eyes glowing a strange red light in the water.

What Nalan Lingyun didn't know was that although the appearance of this fish was no different from that of ordinary koi, it was full of traps and gears on the inside, and it was a clever trap fish.

In the belly of the koi, a golden fragment was hidden without any flaws.

Nalan Lingyun was the most careful, and he had doubts in his heart, but he never mentioned this matter to the second person.

Many times, she had the idea of catching the fish and finding out, but in the end, she resisted the impulse.

When Nalan Lingyun was refining the elixir, his mind was full of thoughts, and it was difficult to calm down, and he almost wasted a furnace of precious Linglong Pill.

There are many similarities between medical alchemy and Taoism, and there are many kinds of fire and Dan furnaces.

The difference is that the materials used are very different.

Taoists use gold and stone as alchemy raw materials, while doctors mostly use herb and tree essences as medicine.

Nalan Lingyun has studied medical skills with her predecessors since she was a child, whether it is acupuncture, decoction or alchemy, she has a deep attainment.

In the early hours of the morning, Nalan Lingyun returned to the house and fell asleep after confirming that the Linglong Pill he had practiced was flawless.

Day 2.

Heavy rain fell, lightning and thunder.

At one o'clock in the afternoon, it was the time agreed by Nalan Lingyun and Xu Zhizang and others to evaluate Dan.

In the main hall of Tianchi Medical Village, everyone was talking.

Sima Jiu and Li Jiancheng exchanged heads and talked about something.

Feng Li behind him yawned, and Yuan Feng looked like he had nothing to do with himself.

The father and daughter of the Xu family and Wei Yingtian stared at the dark circles under their eyes, looking at the back hall with blank eyes, as if expecting it, and even more hoping that Nalan Lingyun's alchemy would fail.

Today's evaluation of Dan is an internal matter of the doctor, and Sima Jiu and the others are just bystanders.

It's just that Feng Li and Yuan Feng don't seem to have the intention of watching, whether he took out his sword, as if measuring the size, and like comparing how big the pit to dig.

Poor doctor elder Xu Zhizang, holding Bian Que's order, but he was worried and uncomfortable.

Sima Ruohua sat behind Sima Jiu, she disliked Li Jiancheng blocking her sight, and naughtily pulled his hair.

The affairs of men and women were not much cared about, and since Li Jiancheng did not object, they did not feel inappropriate.

At one o'clock in the afternoon, Nalan Lingyun appeared on time.

A medical disciple appeared in the main hall with a plate containing Linglong Dan and Tianyun Dan.

Linglong Dan is completely different from Tianyun Dan.

The Linglong Dan is white and crystalline, like the white characters of Go.

Tianyun Dan is black and shiny, like a sunspot in Go.

Xu Zhizang glanced at the Linglong Pill refined by Nalan Lingyun, picked up another one and put it in front of his nose and sniffed it, his face slowly gloomy.

As soon as the so-called connoisseur makes a move, he will know if there is one.

Although Xu Zhizang's medical ethics are corrupt, the Xu family is actually good at pills.

With the shape and charm alone, Xu Zhizang knew that Linglong Dan was extraordinary.

Xu Yanyun pretended to come forward to comment, and before she could taste it carefully, she asserted that the grade of Linglong Dan was far below that of Tianyun Dan.

Xu Zhizang's eyes lit up after glancing at the medical disciples in the main hall.

According to the rules of the doctor's family, only the disciples whose strength has been recognized by the elders of the doctor have the qualification to evaluate the pills of Doudan.

In the process of fighting pills, if the grade of Dan is difficult to distinguish, the result of Doudan will be judged by the principle that the minority obeys the majority.

Today, among the disciples of the medical family, the disciples who are really qualified to taste the pill are either out of the house or are urgently recruited into the imperial capital.

At the scene, only Nalan Lingyun and the father and daughter of the Xu family were qualified to taste the pills.

As long as you have a clear conscience and insist that the grade of Tianyun Dan is better than that of Linglong Dan, the Xu family's wife and daughter will win.

"Linglong Dan, there is indeed something outstanding, but after all, the junior sister is young, the dispensing is unbalanced, the heat is not right, and she has not played the great role of Linglong Dan cold supplement, and the rating is indeed below Tianyun Dan." Xu Yanyun had a proud face.

Xu Zhizang shook his head and kept glancing at the expressions of Sima Jiu and the others.

Li Jiancheng saw Xu Yanyun talking nonsense, he was angry in his heart, and he was about to go crazy, but he was stopped by Nalan Lingyun gently shaking his head.

"Linglong Dan, moisturizing people with cold, and nourishing the five internal organs and six internal organs by walking the yin and dimensional veins, is a good medicine for healing. Tianyun Dan is the medicinal property is positive, and the bones are strong. ”

"Uncle Shi's Tianyun Pill is indeed good, but just based on Senior Sister's words, it is judged that Linglong Pill is inferior to Tianyun Dan, which is sloppy, Senior Sister, do you know that the medicinal properties of Black Moon Lingzhi are far inferior to the Spotted Bear Heart." Nalan Lingyun's tone was calm.

Although Xu Zhizang had something in his heart, he couldn't say it.

After all, he was an elder of the doctor's family, and the way of medicine had long been immersed in his soul.

He can do it if he buys murder, but if he wants to speak with his conscience, he really can't say it.

Xu Yanyun had no scruples, and said: "Drugs with contradictory properties, the efficacy is really difficult to judge, and the world's medicines, if you only use the grade of medicinal materials to judge the efficacy, wouldn't it be a self-smashing doctor's signboard?" ”

She looked mean, the corners of her mouth were slightly raised, and she sneered.

"It's better to evaluate the pill according to the rules of the doctor, and now, the medicinal effect of Linglong Dan and Tianyun Dan is difficult to evaluate, so it is better to follow the principle of the minority obeying the majority."

Xu Yanyun recalled the money spent on the Heavenly Fire Killer, and glanced at Wei Yingtian with a smug look on his face.

Seeing Xu Yanyun being so rude, Nalan Lingyun had a faint bad premonition in his heart, and his brows furrowed.

The master has not returned from the house, and in the medical village, he is now the only one who has the qualifications to evaluate Dan, could it be that all this is related to the father and daughter of the Xu family.

"Nowadays, the grade of Dan medicine cannot be determined, but there is a way to do it." Feng Li saw Xu Yanyun playing tricks and said loudly.

"Oh?"

"How?" Many of the disciples of the medical family were suddenly curious.

"Doctors help the world, the quality of the pill, when judged by the efficacy, the two medicinal properties are contradictory, it is better to conduct a direct test, the effect will be known as soon as you try it, just right, Wei Yingtian Wei Gongzi can act as this test product."

When Wei Yingtian heard this, his expression changed greatly.

Since he knew Li Jiancheng's identity, he has kept a low profile a lot, and there are faint signs of breaking away from the father-daughter front of the Xu family.

He knew the relationship between Feng Li and Li Jiancheng, and in the face of Feng Li's suggestion, he didn't dare to refute it openly except for scolding Feng Li for being a bastard in his heart.

"There's nothing wrong with this, the two pills are from the hands of a medical master, and they are naturally worth a lot of money, and Wei Gongzi can enjoy them for free, which is also a kind of fate." Wang Qi clasped his hands in front of his chest, and his face was full of playful expressions.

Feng Li walked towards Wei Yingtian with a smile, wanting to take him to test the medicine.

"This ...... I'm afraid this is not appropriate, the lower body is cold and hot, and if you delay your evaluation, won't it be a pain in the villain. Wei Gongzi was anxious and wise, and said while retreating.

Nalan Lingyun looked at Wei Yingtian's ridiculous movements and smiled.

Sima Jiu stood up and was about to say something when there was a sudden commotion at the gate of the villa.

Afterwards, a disciple of the medical family shouted, "The real person is back." ”

Sima Jiu and the others looked over, and saw that in the direction of the entrance of the medical village, the white yam king was holding Mr. Miaochun, accompanied by a fat-faced monk, and walked towards the main hall.
