In the past thousand years, my appearance has finally changed somewhat, from fifteen or sixteen years old at the beginning, to about thirty years old now, from which I also summarized a rule, thirst blood brings me not eternal immortality, but the speed of aging is a hundred times slower than ordinary people, ordinary people are one year older, and I am one year older......

After the establishment of New China, life became more and more peaceful, and I had to go abroad to find war and chaos, but I didn't want to live that kind of life at this time.

First, I am accustomed to the Chinese way of life and am reluctant to live abroad, second, in the era of cold weapons, I surpass the strength, speed, reaction and physical strength of ordinary people, and can ensure my safety on the battlefield, but with the advancement of the times, the weapons used in modern warfare are becoming more and more advanced, large-caliber bullets, high-power shells, may cause harm to me, I am no longer invincible on the battlefield, for safety, I have to stay away from the battlefield, and strive to adapt myself to peaceful days.

In the past 30 years, I have felt more and more that it is really difficult to move forward in this society without a legal real identity. So, taking the opportunity of the census, I pretended to be a black household with amnesia and couldn't find his family, applied for a new identity named Du Lin in the civil affairs department, and took the college entrance examination.

With the knowledge accumulated over the millennium, I was easily admitted to the College of Traditional Chinese Medicine of Zhonghu Medical University to study the major of integrated Chinese and Western medicine.

Needless to say, I can be a teacher for these TCM teachers, so I focus on Western medicine.

After graduating, I opened a clinic in Zhonghu City, focusing on blood tests, which started with one of my talents.

As early as when I studied medicine under Mr. Sun Simiao, I found that I could clearly know what disease a person had by tasting a person's blood, with a 100% accuracy rate, which I called "tasting blood to recognize disease".

This is also one of the means of making a living for thousands of years, I have been mixed in the wars of various dynasties and generations, specializing in the army as a medical officer, both to easily obtain human blood and to help the wounded. After the establishment of New China, there was no war for decades, so I had to open a clinic.

Due to the decline of traditional Chinese medicine in recent years, most people believe in the test results of Western medicine, so I also did what I liked and engaged in a gimmick of "blood test to diagnose the disease".

There are big hospitals for Western medicine testing, and Chinese medicine treatment is also more popular with old Chinese medicine, and I opened a small clinic when I was young, neither of which are accounted for, so naturally there is no business.

However, I have also accumulated a lot of wealth over the past thousand years, it doesn't matter whether I make money or not, it is naturally best to cure diseases and save people, and I can also take the opportunity to "embezzle" blood bags if there are no patients. Zhonghu City stipulates that medical institutions rated above B level in the city must have one unit of plasma for each of the four blood types, that is, the hemoglobin extracted from 200ml of blood, about 100ml, plus 20ml of anticoagulant, the total amount is 120ml, and the four blood types are 480ml. This blood is almost enough for me to use for two months, and as long as I prescribe a few random blood transfusions during these two months, I can justifiably "use" these four units of plasma.

For the rating of this "B-grade" or above medical institution, I spent a lot of money to purchase several world-class blood analyzers and laboratory equipment, some of which are even more advanced than the city's top three hospitals.

Thousands of years of experience have taught me that there is no oil and salt shop that is not open. Soon, the Zhonghu City Criminal Police Team needed to do an analysis of a drop of blood sample left at the crime scene when investigating a case, because the samples extracted were too small, the city and even the provincial identification center could not do it, I heard that there was such a clinic in the city that "people are stupid and have a lot of money", and purchased the most advanced analysis equipment, so the criminal police team sent someone to me with the sample, that is, the Li Xian mentioned earlier, he was only the deputy captain at that time.

I remember it was a burglary and murder case, a family of three was tragically killed, and the murderer left no traces at the scene, no fingerprints, no footprints, no hair, no murder weapon, nothing. The police speculated that a deceased person had scratched the killer during the struggle, and the murderer was afraid that the police would extract blood or skin from the fingernails, so he simply cut off the hand and boiled it in boiling water. Still, the police found a small patch of blood on the switch of the faucet.

I admire the policeman who found the bloodstain, that is, Li Xian, because the bloodstain is only a drop the size of a millet grain, which can be said to be difficult to distinguish with the naked eye. Generally speaking, such a small amount of bloodstains has no laboratory value, because the amount is too small to even be recognized by ordinary instruments, but this small bloodstain is the only valuable clue to the whole case, and it has become a lifesaver to solve the case.

The head of the criminal police team of the city bureau asked all the major identification centers in the city and even the province, and they all said that they could not analyze such a small amount of samples, and overheard that my clinic had introduced a batch of the most advanced blood analysis equipment, so they came to try their luck here.

That blood sample was indeed too small, if Li Xian hadn't pointed it out to me, I really thought he had given me a blank slide (sample carrier, glass product).

I said to Li Xian: "I can analyze, but I need to dilute such a small amount, and after dilution, I am afraid that there will be no evidence, can you accept it?"

Li Xian looked at me, hesitated for a few seconds, and asked me, "Are you sure?"

"I'm sure of myself, I just don't know if you're sure of me. ”

Li Xian gritted his teeth, "Damn, I've seen a lot of confident people like you, one is really confident in what you have, and the other is not confident in pretending to be confident, but I don't think you are like the latter, Lao Tzu believes in you today, you test it, if it's gone, it's gone, anyway, you can't test it here, and it's useless to keep it." ”

"Okay, you wait, it'll be fine soon. ”

I took the slide, entered the laboratory, locked the door, separated the two glasses, and licked the side of the bloodstains, although the amount of blood was very small, but I was extremely sensitive to blood, and immediately analyzed the physical condition of the owner of the blood.

I threw the slides in the trash and worked on the computer in the lab for a while to make a fake test report.

"Here you go," I handed the fake report to Li Xian, "and the results are out." ”

Li Xian looked at it for a while, and returned the report to me with an embarrassed face, "You are tired, just tell me the results, I know every word on your paper, and I can't even understand a word together." ”
