The two returned to the school and reported the matter directly to the General Affairs Office, and the leaders of the General Affairs Office attached great importance to it and arranged for a teacher named Fan Huajin to assist them in finding out the origin of the Yin Snake.

Mr. Fan is about 30 years old, short and stocky, always with a smile on his face, and looks like he is very talkative.

He is a teacher in the Department of Biology, majoring in the breeding and control of Gu worms, and although this Yin Snake is a condensation of Yin Qi, it also has a certain vitality after refining, so it can be regarded as a kind of Gu worm.

Teacher Fan took Zhang Shang and Fang Yu to his laboratory and took out a set of modern glass instruments, including an iron frame, an alcohol lamp, an asbestos net, a thermometer, a distillation flask, a condenser tube, a horn tube and an Erlenmeyer flask, and built a set of distillation equipment.

Then he poured the three Yin Snakes into the distillation flask, added the pre-prepared potion, and began to heat it slowly.

The three yin snakes were relatively quiet at first, lazily soaking in the hot water and swimming slowly, as if they were taking a bath.

However, as the temperature increased, the three Yin snakes began to become visibly agitated, rushing left and right in the distillation flask, but these instruments were all specially made, and the Yin snakes couldn't hit them at all.

When the temperature on the thermometer rose to 160 degrees, Fan Huajin began to control the temperature, and slowly baked over low heat, and saw that the bodies of the three yin snakes began to shrink gradually, turning into wisps of black gas overflowing from the distillation flask.

Fan Huajin immediately turned on the condensate, and the black gas was condensed and turned into a fishy black juice, which fell into the Erlenmeyer flask drop by drop from the horn tube.

Fan Huajin carefully observed the black liquid under the microscope, then nodded thoughtfully, and said, "Judging from the materials and refining techniques of these three Yin Snakes, it seems that the refiner has not undergone systematic training in Gu worm breeding, and his strength should not be too strong. ”

Fang Yu couldn't help but ask, "Teacher Fan, can you find him out?" ”

Fan Huajin nodded: "I don't think it's a big problem, this person actually uses this kind of Gu insect to harm people, which has seriously endangered the lives of ordinary people, and also violated the safety regulations of the abnormal energy world, it is absolutely impossible for our Shushan Academy to stand idly by." ”

As he spoke, he took out his mobile phone and made two calls, and soon after, Tao Hongcheng, a teacher from the Department of Geography, and another school doctor in a white coat came to the laboratory.

Fang Yu and Zhang Shang both knew Tao Hongcheng, so naturally they didn't need to introduce her, and the school doctor was a woman in her thirties, who had been carrying a small medicine box with her, and Fan Huajin introduced her as Ji Haifan.

"In order to prevent that person from escaping and causing frightening to the general public, we need to arrange the formation in advance and close the battle site, so we need Mr. Tao's help." Fan Huajin said to Tao Hongcheng with a smile.

"No problem." Tao Hongcheng agreed.

"In addition, in order to ensure that nothing goes wrong during the operation, we have to trouble Doctor Ji to accompany us on a trip." Fan Huajin said to Ji Haifan again: "Most of the people who domesticate Gu worms are good at using poison, so I have to ask Doctor Ji to bring more antidotes." ”

"Don't worry, I'll take it." Doctor Ji patted his small medicine box.

"Then it's no problem, with Teacher Tao's formation and Doctor Ji providing treatment, there should be no danger in this line."

Speaking of this, Fan Huajin asked Fang Yu and Zhang Shangdao with a smile, "Do you two want to go together?" ”

"Can we both go together?" Fang Yu was a little surprised.

"Of course, this Yin Snake was originally discovered by the two of you, and besides, doing this mission together will not only increase your knowledge, but also earn a certain amount of credits, you should have no reason to refuse, right?"

"Of course not!" Zhang Shang hurriedly said.

"That's good."

Fan Huajin discussed with Tao Hongcheng and Ji Haifan, then took out a piece of paper, folded it into a paper crane in three or two clicks, and then poured all the black liquid in the Erlenmeyer flask on the paper crane.

As soon as it came into contact with the crane, all the black liquid penetrated into it, dyeing the crane black.

Then I saw that the paper crane seemed to suddenly come to life, flapped its wings twice in the laboratory, and then flew outside.

"Let's go, follow this paper crane and you can find that guy." Fan Huajin greeted.

Following the paper crane, Fang Yu and the five of them came all the way to a community near the Conservatory, and the black paper crane flew about two meters above the ground along the way, but the pedestrians around them didn't see anything.

This community is an old community ten years ago, the community is quite large, the occupancy rate inside is also very high, in addition to the residents, many small merchants and hawkers rent the façade houses along the road in the community to do business, it seems that the whole community is particularly life-like.

The crane led them to a building, and then began flapping its wings at a façade on the first floor, apparently signaling the location of the target.

And Fang Yu also found the strangeness here, the location of this façade house is quite good, in the center of the community, the sign hanging at the door shows that this is a flower shop, and there is also a fruit shop, a barber shop and a chess and card room next to it.

It's afternoon, and the other shops are open for business, but this flower shop is closed.

And there is a faint fishy smell coming from the gate, but it is hidden in the fragrance of flowers, so it cannot be smelled if ordinary people don't pay attention.

"Brother, may I ask, why isn't this flower shop open? Is the owner not there? Fan Huajin asked the fruit vendor next to him, and handed over a cigarette at the same time.

"Oh, you said Xiaohu." The peddler took the cigarette and said, "She's a little weird, she usually does business for three days and fishes and two days to dry her nets, but I see that she has so many flowers, and many of them have withered before they are sold, so it's strange that this business doesn't lose money." ”

Listening to what the vendors say, everyone knows that they are in the right place.

"Teacher Tao, this is densely populated, in order not to cause a big impact, please arrange an illusion circle and a closed circle in advance, and then let's catch turtles in an urn."

"No problem." Tao Hongcheng nodded in agreement.

She was ready before she came, so she didn't need to draw on the spot, she just took out two drawn runes from her bag, pasted them on the door of the flower shop, and entered an aura.

I saw that the two rune papers suddenly burned, and a white mist that could not be seen by the naked eye emanated from above, enveloping the entire flower shop and Fang Yu and the five of them.

The peddler was talking and fiddling with his fruit stand, and when he looked up again, he found that the people he had just spoken to were gone, and he couldn't help but feel a little strange.

He didn't think much of it, though, and quickly forgot about it behind his ass.
