After Yang Jingtian's mood calmed down, Liang Fei pulled him and squatted down by the fish pond together.

Asking a worker to fish out a koi fish into the small fish tank in front of him, Liang Fei began to observe the fish carefully.

Obviously, this koi fish is of a very good species, it is a purebred Showa tricolor from his own island of Wakoku, and it is in good condition, so it is no wonder that it can be sold for a high price of 500,000 pieces.

But now Liang Fei is not paying attention to the color and quality of this koi, but in his gradually unfolding perspective eyes, he clearly sees that the vitality of this fish is slowly fading, if it is not rescued as soon as possible, even if this fish can drag on for a few days without dying, it will be wasted!

The experience of treating sick fish is not unexperienced before for Liang Fei. In the past, at the auction, he had forcibly revived a dying supreme Fulong Emperor.

And now the situation of these fish is obviously much better than the situation of the original Fulong Emperor. If you want to be treated, you only need to put them into the fairy lake water of the space, and they will be rejuvenated in a few days.

Liang Fei knew it in his heart, but he had to figure out what Li Changqian had done to these fish to make them slump. Moreover, it can hide from the eyes of so many fish farming experts, so that everyone can not find the real cause.

"Ah Fei ......"

Seeing Liang Fei staring at the fish in the fish tank, but there was no reaction for a long time, Yang Jingtian couldn't help but be shocked, and just wanted to ask Jiao Sheng, but saw Liang Fei gently shake his head at him, signaling him not to speak for the time being.

At this time, Liang Fei stared intently at the koi lying in the fish tank for a while, and finally slowly reached into the fish tank, and then pointed at the back of the koi with his right index finger.

Although his actions seem simple, in fact, he is using the finger of gold, combined with the eye of foresight, to begin to probe the changes and abnormalities in the breath in the fish's body.

Under his fingers, the koi, which should be extremely lively in normal times, was like a schoolboy who had made a mistake, lying there motionless, at the mercy of Liang Fei.

Looking at Liang Fei's actions, Yang Jingtian was also confused. Although he knew that Liang Fei was a traditional Chinese medicine practitioner, and his medical skills were very high. But Chinese medicine healers, I haven't heard of it, you can also heal fish. Taking a step back, even if it can be cured, this method of healing is ...... Doesn't it seem too unusual? Is it taking the pulse of the fish?

While Yang Jingtian was looking at it puzzled here, Liang Fei suddenly stretched out his hand from the water and asked Yang Jingtian, "Brother Yang, did you buy this fish from Li Changqian?"

"Well, yes!"

Yang Jingtian glanced at the fish, nodded and replied without thinking about it.

"Good!"

Liang Fei also nodded, and then said to the workers on the side: "Quickly catch a fish from your own family and give it to me." ”

Although the worker didn't understand Liang Fei's purpose for doing this, he still fished out a Taisho tricolor koi from the fish pond according to his words, put it into the fish tank, and said to Liang Fei with a wry smile: "Liang Shao, this was originally the best species we raised here, but who knows that now it is like an infectious disease, and it has withered like this." ”

Contagious disease!

Although this worker said it casually, the speaker was unintentional, and the listener was intentional, and after listening to his words, Liang Fei was shocked in his heart, and he was even more in mind.

Not only Liang Fei was like this, but Yang Jingtian also frowned and asked Liang Fei, "Ah Fei, what do you say...... Did Li Changqian's bastard infiltrate some diseased fish into that batch of fish, and then there would be such a large-scale infection?"

"Brother Yang, didn't you go through a serious inspection when you bought fish?" In response to Yang Jingtian's question, Liang Fei's expression sank, and he asked instead of answering.

"This ......"

When Yang Jingtian heard this, his brows couldn't help but lock tighter. Ban Xiang shook his head in distress and said: "When we bought the fish, we all invited fish industry experts to carefully screen each fish to ensure that there were no problems before we could pay with confidence." ”

Speaking of this, Yang Jingtian's expression couldn't help but look stunned. Because, without Liang Fei's explanation, he himself had already denied his question just now.

However, if it is not a very serious infectious disease, how can so many fish get sick at the same time?

"Brother Yang, the common infectious diseases of fish are roughly divided into three types. The first is hemorrhagic disease, in which the muscles, mouth, and base of various fins are congested, especially the anal fin. Peeling off the skin, punctate bleeding can be seen in the muscles, and all the muscles of the severely diseased fish are red. Sometimes the body of the fish can be seen to be red, which can be judged without peeling it off. Sometimes the gill covers, large jaws, eye circles, and intestines are also congested, and the gills lose bright red or are pale.

The second is enteritis, the fish body is red and swollen, and in severe cases, there is blood pus or yellow mucus flowing out of the abdomen, and the intestine is partially or completely inflamed, and it is purple-red. The third is coccidiosis. The gill filaments are pale, and in severe cases, the abdomen is slightly distended, and there are many rice-grained coccidiosis cysts on the inner wall of the front end of the intestine. ”

Liang Fei used the same way before, touching the Taisho tricolor koi with his fingers, and explained to Yang Jingtian: "Most of these infectious diseases can be detected by the naked eye. However, if you look at these fish, their various body features are very normal, and from the outside, they are completely indistinguishable from healthy fish except that they have no energy. ”

"yes, I've found out about that a long time ago. The fish experts I asked were also very strange, but they couldn't figure out what kind of disease these fish had.

Liang Fei's statement immediately aroused Yang Jingtian's resonance, he shook his head in distress, and said with a gloomy expression.

"Mr. Yang, will it ...... These fish are getting an infectious disease that hasn't been discovered yet?"

When Yang Jingtian was sighing, the workers on the side suddenly came over and put forward their opinions.

"Impossible!"

While they were talking, Liang Fei had already made careful observations and examinations of the two fishes, and he already had a clear understanding in his heart.

When he heard the opinion of a worker, he immediately shook his head with a smile and said: "In fact, fish, like people, as long as they are sick, they will inevitably have various physiological reactions and external manifestations.

Even if they get some kind of undetected infectious disease, it can't behave like this. At least it can be seen from beyond their body surface. ”

Any conceivable speculation was denied by Liang Fei, which made Yang Jingtian and the workers feel even more helpless.

However, looking at the look of confidence on Liang Fei's face again, Yang Jingtian couldn't help but feel a glimmer of hope in his heart, and asked in a sparkling voice, "Ah Fei, have you discovered something?"

"Yes, I did find out!"

Liang Fei didn't want Yang Jingtian's heart to hang uneasily like this anymore, so he replied with a smile.

"Oh, what's that? Tell me?"

When Yang Jingtian heard this, he suddenly felt refreshed, and hurriedly pulled Liang Fei's sleeve and asked urgently.

"Brother Yang, don't worry!"

Liang Fei was not in a hurry to answer, but pulled Yang Jingtian, pointed to the two fish in the fish tank, and asked slowly: "Brother Yang, you might as well take a look first, what do these fish look like with dull eyes and irritability?"

"Like what?

Yang Jingtian's gaze at the two fish was a little dull, and he couldn't figure out what Liang Fei meant for a while.

What else can a fish look like besides a fish......

Liang Fei glanced at Yang Jingtian and didn't say anything, then turned his gaze to the workers on the side and asked, "You say, what do they look like?"

Just from the fact that the worker just said that these fish were suffering from some kind of undiscovered infectious disease, Liang Fei could feel that this guy was an extremely imaginative person. And in many cases, the richer the imagination, the easier it seems to grasp the crux of the matter.

"Like ...... This ......"

Seeing Liang Feixiang ask spontaneously, the worker also stared at the fish in the fish tank, touched the back of his head and thought for a long time, and then muttered: "I don't think they are like anything else, but like people who smoke opium......

"Xiaodai, don't talk nonsense!"

Before the worker's words were finished, Yang Jingtian scolded him speechlessly.

"Brother Yang, what he said is not bad at all!"

However, Liang Fei smiled and stretched out his hand to stop Yang Jingtian, patted the worker's shoulder, and said firmly: "These fish really look like drug addicts!"

"Ahh

Seeing Liang Fei's serious look, Yang Jingtian couldn't help but be shocked in his heart, and suddenly seemed to think of something in his mind, and asked in surprise: "Ah Fei, do you mean ......?"

"Not bad!"

Before Yang Jingtian's words were finished, Liang Fei's expression suddenly became extremely serious, and he nodded in a deep voice and said, "These fish have all been injected with drugs!"
