President Yu told Chu Ge that this is a special parasite and microbial reaction reagent.

Because the ecological environment of the Immortal Cultivation Realm, the Illusion Realm and the Earth is different, there are many unique parasites and bacteria in the three worlds, and even some very common microorganisms, such as E. coli, have also given birth to many variants.

Whether it is an earthling, an immortal cultivator, or a magician, they all carry large bacteria and parasites on their bodies, and if they cross into the other world, these bacteria and parasites will also be brought together.

Then, if you find a biochemical agent that is very sensitive to these microorganisms, and if you come into contact with each other, you may have an allergic reaction and determine the identity of the other party.

Even, if the information is sufficient, it can be accurate to the other party's hometown.

Because the Immortal Cultivation Realm is actually not a complete world, but countless "archipelagos" connected by teleportation arrays, each of which has a unique ecosystem with small sparrows and complete organs, and many bacteria and parasites have different forms.

For example, Dongman? Tiezhu's hometown "Hundred Wilderness" and the hometown of the little palace master "Luofeng Mountain" have unique features, animals, plants and microorganisms, all of which can be tested.

And this time......

"Oops."

Chairman Yu looked at the spray used by the technician and sighed, "Judging from the microbial and parasite reactions, the other party is from the 'Yanruin' of the Immortal Cultivation Realm. ”

President Yu told Chu Ge that Yanxu was a place very close to the inner circle of the Immortal Cultivation Realm, and there had been a splendid civilization and several great sects that had flourished for a while, so that many immortal cultivators who had traveled to the earth had heard of its prestige.

However, the good times did not last long, perhaps the ups and downs of the spiritual tide caused the drastic changes in the heavens and the earth, in short, the ruins of the flames had collapsed hundreds of years ago, turning into a volcanic eruption, magma flowing, and a terrifying area full of sulfur and mutated beasts, just like the Hell in myths and legends, even immortal cultivators regarded it as a land of poor mountains and bad waters.

After the collapse of the once prosperous wealthy clans, countless ferocious evil demons were born on their corpses, and they marched in all directions with great ambition - just like after the collapse of the regular army on the earth, countless wandering soldiers became warlords, mercenaries or bandits.

Therefore, for more than a hundred years, the evil cultivators from Yanxu have always been a very troublesome existence in the entire immortal cultivation world.

Different from the "Hundred Wilderness" that is also poor and bad, the Hundred Wilderness lacks resources from the beginning, has a very low level of development, and is in the stage of primitive tribes. Iron Pillar" is such a murderer, more than arrogant, not enough treacherous.

However, the evil cultivators of Yanxu have superior wisdom, cunning strategies, and magical powers and powerful magic weapons inherited from ancient times, which are a hundred times more dangerous than the hundred barbarian tribes.

"It turned out to be a Yanxu evil cultivator who crossed over to Lingshan City, and I don't know how long he has been dormant and how much knowledge on the earth he has absorbed, this is a big deal!" Chairman Yu said worriedly.

The findings in the rental house confirmed her judgment.

Although most of the space is clogged up with garbage and rags, a desk in the corner is quite tidy, and under the table, there are mountains of seemingly inconspicuous old books.

From the left-hand side, there are dictionaries and elementary school textbooks.

Open a look, each page is densely filled with small characters, the strokes seem to be immature, but there is a faint hidden bit of muscles, the identification results of the forensic technicians, the pen and ink are very new, should be left within a year.

In other words, it was all the handwriting of the "Yan Luo", who used dictionaries and elementary school textbooks to study the words of the earth seriously, and even copied each textbook hundreds of times.

At first, he could still see a little immature, but gradually, he was able to write simplified characters as handsome and elegant as the immortal cultivation runes, and even many natives of the earth, such as Chu Ge, couldn't write such beautiful characters.

Then, he began to learn about computers and surfing the Internet.

The first textbook I used was called "Learning to Surf the Internet in 30 Days - Teach You to Be a New Human".

The technicians of the forensic department carefully opened the textbook and saw that it was written like this:

"Boys can call themselves gg, girls can call themselves mm, the moderator is called Banzhu, the master is called prawns, and goodbye is called 886......

"Example sentence: Hey, such a coincidence, you also surf the Internet, I'm gg, are you mm?"

"What the hell is this?" Chu Ge was completely blinded, what kind of textbook is this!

"This is a textbook a long, long time ago, when the Internet was just emerging, and it can be seen from this textbook that the other party is definitely an immortal cultivator."

President Yu said with a solemn expression, "Children on the earth have been surrounded by the Internet since childhood, and the speed of information update is extremely fast, even if they are new to the Internet, they will not say such old-fashioned words as 'surfing the Internet', only the immortal cultivators who have just crossed over do not understand the development of the earth and the Internet at all, and it is impossible to ask outsiders these strange questions, so they will randomly find a seemingly basic textbook to learn."

"However, he learns very quickly, and you can read this textbook again."

Chu Ge glanced at it, and gasped, and the other textbook was "JAVA from Beginner to Mastery".

When I opened it, I saw that the first dozen or so pages were all note-taken, exactly the same as the handwriting in the elementary school textbook.

However, it can be seen that this "Yan Luo" is not very good at facing object programming, and there are a lot of question marks in the notes, and the more you go to the back, the more messy the handwriting is, the more impetuous, and it is a bit of a meaning to go from getting started to giving up.

"This guy crossed over, it shouldn't be more than a year, at the beginning I learned how to 'surf the Internet', and now I have begun to learn JAVA, its wisdom is excellent, the heart is forbearing, and the learning ability is strong, which can be seen."

Chairman Yu frowned deeply, "Even if he can't learn how to program, at least, he is familiar with most of the common knowledge on the earth, and it must be no problem to disguise himself as an ordinary earthling, such a person has been hiding under our noses for so long, and we don't know anything, it's really terrifying!" ”

Indeed, the threat of immortal cultivators is not simply based on progression.

If it's Dongban? Tie Zhu, a guy with well-developed limbs and a simple mind, even if he has the strength of the Dan period, he can always solve it by mobilizing the army to bomb indiscriminately.

But such a sinister and cunning person as "Yan Luo", who is hidden in the city with ill intentions, even if he only has the strength of the foundation building period, he has come and gone without a trace, and using the army to deal with him is like using anti-aircraft guns to fight mosquitoes, and he can't hit him at all.

And the series of evidence that was discovered next quickly confirmed that this gentleman was indeed not a law-abiding and good person, but an extremely dangerous demon murderer.

It was translucent cans filled with formalin-soaked organs.

When you open a pile of garbage, you can see hundreds of such jars, heart, liver, spleen, lungs, kidneys, all kinds of deformed and twisted organs, like a bloody nightmare.

In such a terrifying scene, several special police officers couldn't help but faintly gause, and Chu Ge also felt dizzy, like a few pieces of rancid minced meat in his throat and eyes.

The good news is that many organs do not appear to come from humans, but from livestock such as pigs, dogs, cows and sheep.

The bad news is that there are still some organs of unknown origin and covered with tumors, as if they have special research value.

Among the second-hand books collected by "Yan Luo", many of them also involve human anatomy and oncology.

Moreover, it seems that he is very interested in the field of "spontaneous combustion of the human body", and has collected a lot of books on this subject.

At this time, there was an exclamation from the bedroom.

Chairman Yu and Chu Ge hurriedly ran in to take a look, and found the technicians of the forensic department who found a corpse from under the open bed.

Under the bed, the ground was full of dense runes, as if they were made of rune ink mixed with blood mixed with special animal fat, and they actually outlined a three-dimensional effect on the plane, and the light of thousands of runes was still flickering, interlaced from a raging red lotus.

Above the red lotus, there was a black charred corpse, burned to the size of a doll, but without the slightest twisted posture of pain and struggle, as if a person had been reduced in equal proportions and painted black, sitting cross-legged on top of the fire lotus talisman array, and even a little bit of benevolence and joy.

"Is this 'Yan Luo'?" President Yu whispered to the technician of the forensic department.

I'm afraid not.

The forensic technician extracted a small piece of fabric from the charred corpse and quickly analyzed the material.

This is the fiber on a middle school uniform, and primary and secondary schools in Lingshan City will use this material to make school uniforms.

Moreover, judging from the analysis of the charred corpse's teeth, he is very young and has received orthodontic treatment before.

This is an Earth Boy.

may have been deceived into a rental house by Yan Luo's rhetoric.

But he didn't have the same good luck as Ye Feng, but was burned alive by Yan Luo.
