At the door of the laboratory, Lan Kexue was waiting anxiously. "Why has it been so long? Lan Kexue complained as soon as she saw Ji Sanhai, but soon saw Teacher Jin in the back. "Mr. Jin, why are you here? Teacher Jin smiled and said, "I heard that you are going to use the instruments of the biology laboratory to study biology-related problems, and I just didn't have a class, so I came over to see if I could help." Teacher Lan, you won't mind, right?" Ji Sanhai said in his heart, this Teacher Jin obviously came here because he was afraid that her biology laboratory would become a place for dating.

Lan Kexue smiled, "Since my sister is free, of course it's good, I heard that my sister is stronger than many biological experts." Teacher Jin opened the door of the laboratory, "There are several instruments in my laboratory that are my own, not from the school, but Sister Lan needs it, and I am very willing to borrow it from you." Ji Sanhai was stunned when he listened to it, why did these two people suddenly become sisters? It's just that these words sound so awkward, where do they look like sisters!

After some preparation, Lan Kexue took out the test tube, "It's the liquid in it, and I need Mr. Jin's help to analyze it." When Mr. Jin saw this test tube, he believed that these two people were really here to do experiments, not to use her laboratory to do something they loved.

"No problem, it's a trivial matter. Mr. Jin skillfully sucked out a little liquid with a straw, applied it to the glass piece, and put it under the microscope to view. "Huh, this liquid seems to be ...... I don't remember exactly, so you can take a look first, and I'll check the information. "Mr. Jin did have some impressions when he saw the filaments in this liquid.

There seem to be some long, narrow filamentous objects floating in the liquid under the microscope, which do look a little unfamiliar. Lan Kexue and Ji Sanhai couldn't see the origin of this liquid, so they looked at each other and had to wait for Teacher Jin to come back. "Xiaoxue, this Teacher Jin seems to have some opinions about you?"

"I don't know, but I heard that she seems to have had a fight with her boyfriend recently, maybe she is not in a good mood. Lan Kexue carefully put away the test tube containing the liquid, "We can't pin all our hopes on Mr. Jin, we have to think of some other way." This is supposed to be the liquid left by the murderer, and it is very difficult to find the murderer with just this drop of liquid. ”

Ethereal Lingyue appeared beside Ji Sanhai at this time, "Xiao Ji, it's just the two of you now, you still don't give her that thing." Ji Sanhai suddenly realized, "Sister Yue, you're right, I'll give it." Thinking of this, Ji Sanhai took out a pendant, "Xiaoxue, this is my gift to you." Lan Kexue was thinking about how to find the murderer, and suddenly found the jade pendant in front of her, and she didn't react for a while, "This, give it to me?"

"Yes, this jade pendant is a talisman that can keep you safe. Ji Sanhai looked at Lan Kexue's expression, he didn't seem to like it very much, and his heart couldn't help but tighten. Lan Kexue took the pendant, and her face slowly glowed, "This thing is so beautiful, even if it can't keep it safe, I like it very much." But why are you giving me a gift?"

"Uh...... I just saw that this pendant was beautiful, so I wanted to buy it for you, for no particular reason, hehe. Ji Sanhai couldn't tell Lan Kexue about the future predicted by the dream, so he had to answer casually. The huge laboratory was extremely quiet, Ji Sanhai didn't know what to say or do for a while, and Lan Kexue seemed to be waiting for something, and it was difficult to hide a trace of shyness.

Although Ji Sanhai knew that Lan Kexue was likely to be his future wife, he was actually timid at this time, and the nightmare of killing Lan Kexue with his own hands was probably not so easy to get rid of, unless he had a way to prevent that kind of thing from happening. Suddenly, Ji Sanhai thought of something, "Xiaoxue, can't your instrument find this liquid?" We searched the attachment of the convenience store, and maybe we can find the same liquid." ”

Lan Kexue shook her head in surprise, obviously not expecting him to suddenly mention this problem, "This method is theoretically feasible, but the actual use of it is a big problem. As you can see, my device is just a portable detector that I carry with me, and it's actually used for body searches, and it has some reaction to different energies. Unless we search every inch of land in the vicinity, but time does not allow it, the longer the time, the less remnants of the alien energy remain, and these few drops of liquid are not volatilized because of the large amount of blood. ”

"Doesn't country M have an ability detector similar to an alarm device?Isn't there one in country C?" Ji Sanhai remembered the alarm he had snatched from Hongye's house before, and it couldn't come in handy because it lacked the main control part. "Hehe, I didn't expect you to know a lot, that's the latest product of country M. We in country C have only bought a few sets, and it will probably take a year or two to imitate them. However, if I really have that instrument, a little modification to connect it with this instrument in my hand may really really improve the detection range of my instrument. Lan Kexue said casually.

Ji Sanhai heard it clearly, his heart was excited, and his voice was a little louder, "Xiaoxue! I ...... "cough! Teacher Jin walked in from outside at this time, obviously he heard Ji Sanhai's affectionate name just now, and glanced at Ji Sanhai with great meaning, "Don't talk about it yet, I know what this liquid is." ”

"Mr. Jin, please tell us quickly. Ji Sanhai hurriedly asked. "This liquid is supposed to be a saliva mixture, which is saliva. I did have some impressions of the filaments inside, so I went to check the information, and it turned out to be very close to a chameleon unique to country M. The chameleon's oral epidermal cells will fall off from time to time, which is the filament seen under the microscope, and I don't know that there are other creatures that have this kind of saliva. I'm curious, where did you find this liquid?" Mr. Jin looked at the two of them.

This conclusion is a bit too incredible, the chameleon of country M? Could it be that the murderer brought a chameleon pet with him? When she heard that it was saliva, Lan Kexue was really happy, if it was the saliva of a criminal, it would be possible to find the murderer by comparing the DNA, but I didn't expect it to be the saliva of the chameleon. "Mr. Jin, are you sure?" asked Ji Sanhai tentatively. Lan Kexue was also puzzled. "What I just said is just a preliminary judgment, it is not difficult to prove that it is not difficult, just do a DNA test, I happen to have one such device. Mr. Jin also seems to be interested.

"Wow, Mr. Jin, you even have this kind of instrument, it's expensive, right?" Ji Sanhai couldn't help but reach out and touch the DNA detector when he looked at it. "Don't move around, it's really ridiculously expensive, and I borrowed it too. Mr. Jin connected the instrument to a computer and began to analyze. After a short time, a set of DNA sequences was displayed on the computer screen. "Now I'll find the DNA sequence of the chameleon and compare it. Mr. Jin called up the relevant data of the chameleon from the database for comparison, "Hey, it's not exactly the same, but it's close." Most likely a variant of the chameleon. ”

Ji Sanhai and Lan Kexue looked at each other, it seemed that it was really related to the chameleon of country M? The two of them thanked Mr. Jin and left the laboratory. "Xiao Ji, you seem to have something to say to me when Mr. Jin came in just now. Lan Kexue remembered Ji Sanhai's excited expression at that time, there should be some good news.

"By the way, I mean to say that I have a part of that country M ability alarm at home, why don't you try to use it. As soon as Ji Sanhai's words fell, Lan Kexue picked up Ji Sanhai and ran downstairs, "Without further ado, take me to your house!

Lan Kexue's speed Ji Sanhai was no longer strange, and it didn't take long to arrive at Ji Sanhai's doorstep. Ji Sanhai quickly took the ability alarm out of his home, and Lan Kexue couldn't wait to study it in the car. "Yes, it's really a domestic product. You got this stuff too, it looks like I really underestimated you. ”

Ji Sanhai smiled, "Actually, I also grabbed it at that time, I thought it could be used as an alarm." Later, I learned that this instrument could not be used alone, and a host was needed. Lan Kexue took out her detector from her bag, looked for a few more data cables, and found that one was just right. "It's almost usable, and when you put it together like this, the accuracy is naturally worse, but it doesn't matter. I'm going to write a simple program and then synchronize the two instruments. Lan Kexue stared intently at the display of the instrument, her fingertips fluttering.

"In order to save time, you can drive, I will need a lot of time to complete this, first go to the scene of the crime to find clues. Lan Kexue said this, got off the car and swapped places with Ji Sanhai. Ji Sanhai naturally won't have any problems driving this car, but it is much slower than Lan Kexue.

When the two men came to the convenience store again, they found that the police had left. The cordon is still there, and the door is sealed. "How is it?" Ji Sanhai looked at Lan Kexue for a while, and was testing the assembled instrument. Lan Kexue took a deep breath, "Cheng Cheng Cheng will look at this." After that, he restarted the instrument, and then an excited look appeared on Lan Kexue's face, "It's successful! Haha, Xiao Ji, look." "On the screen of the instrument, you can see several different curves pulsating, and you can hear the sound of electromagnetism.
