Xu Yingdong stayed in the laboratory for another hour and a half after getting off work before leaving. He took off his white coat and changed into his usual clothes, and walked quickly out of the hospital gate.

Judging from the appearance, Xu Yingdong is tall and well-dressed, this is a fashionable young man, if he hadn't seen him in the hospital, no one would have thought that he was already an internationally renowned hematology expert.

Xu Yingdong aspired to study medicine from a teenager, and approached his goal step by step with excellent results, in the choice of major, many powerful mentors persuaded him to choose surgery that is easier to achieve fame and fortune, but he seems to have chosen the hematology department very early, and then became a specialist doctor without accident. In the exchange and study with foreign countries also quickly attracted the attention of the industry, he could have easily stayed in those international medical centers with a thunderous name, but he resolutely chose to return to China, of course, the domestic first-class hospitals have also thrown olive branches, the reason why he finally chose the first hospital in the city, because the hospital leaders agreed to approve a laboratory with complete facilities for him to use.

A young talent like him has naturally faced a lot of temptations, beauty and money have appeared, but his life has always been very simple - either at work or on the way to work, there are many senior sisters and sisters who pursue him and fail to say half jokingly and half complaining after touching the nail, Dr. Xu seems to be marrying his beloved blood virus, and now it seems that there is really such a trend......

Xu Yingdong's apartment is not close to the first courtyard of the city, about five or six kilometers away, but he never drives, but commutes to and from work on foot.

The road from the hospital to the apartment is almost the most prosperous area of the city, with shops, large shopping malls and amusement parks along the way, so there are also a lot of children's laughter, Xu Yingdong occasionally smiles unconsciously when he sees them, but sometimes subconsciously thinks of himself as an "ominous" person, and quickly avoids them when he sees them rushing towards him.

Today, as usual, it was dark when Xu Yingdong left the hospital. He lowered his head slightly, thinking about the little girl who had just been admitted to the hospital.

Because most of the time he doesn't smile, Xu Yingdong was marked with a "cold" evaluation, only he knows in his heart that this is actually an occupational disease or a professional habit, in this professional practice, he has seen too much life and death, if he really wants to cry and laugh with patients, I am afraid he would have collapsed long ago. So he could only force himself to be numb.

Wu Doudou suffers from a very typical acute leukemia, the degree of malignancy is very high, although there are examples of cure, but can not be used as an ordinary clinical reference, modern medicine has developed so far, the most dangerous liver cancer lung cancer has been gradually overcome, even if it is advanced, as long as the method is appropriate, there is a fight, but Wu Doudou's disease is still the executioner who makes most families helpless. Xu Yingdong has been working on a new experiment recently, and he has made little progress, but as long as Wu Doudou's family does not give up easily, he is willing to fight with this girl.

Xu Yingdong thought about the next treatment plan and several possibilities of accidents, he left the main road and turned into a small alley, the purpose of which was not to get closer, but to covet the silence here.

A heavy footstep followed behind Xu Yingdong, which finally caught his attention.

Since he can remember, Xu Yingdong has found that things within a radius of 200 meters cannot escape his ears and nose, that is to say, within 200 meters, whether you are muttering or rumbling in your stomach, or even putting a fart that is so slight that only you know, Xu Yingdong can hear and smell clearly, he will never forget that he sat in the classroom at the end of the corridor, heard the head teacher in the office at the end of the corridor and other teachers whispering about the principal's gossip, when he and other classmates asked for verification, the classmate was at a loss.

Yes, it took Xu Yingdong a longer time to discover that others did not have the same abilities as him.

When he was called a parent by the teacher because of Xu's strange behavior, his father told him a secret that night - he was a member of the strongman clan. After that, his father was secretive and rarely mentioned this matter again, and it took Xu Yingdong for a long time to finally figure out that most of the other members of the so-called strongman clan were different from him, they were better at fighting and self-recovery, and Xu was a special example in the strongman clan: his ears and nose were exceptionally sensitive, and as for eyesight, needless to say, as long as he wanted, he could see the hair on the nose of the driver in the car a kilometer away without any equipment.

His father told him that if he wanted to be safe, he had to hide his abilities, and that if he was discovered, he would be sent to a psychiatric hospital or a research institute, and unlike those tough clansmen, he had no ability to protect himself.

For so many years, Xu Yingdong has strictly fulfilled his father's instructions, and by the way, he has developed the habit of never mixing things that have nothing to do with himself, because of the convenience of his body, he can inadvertently find out a lot of secrets. Over the years, the work has gone to society, and it is a realm of refinement, even if a colleague says bad things about himself next door, he just smiles slightly, most of the time, he only takes the sound he hears as a background sound and does not delve into it, and you can't study it deeply, you can't hear the two people 200 meters away saying that so-and-so's wife gave a certain green hat and follow them to see what so-and-so looks like, and you don't have to hear a few CEOs in a passing luxury car secretly discussing which stock to make red and follow the trend. Xu Yingdong has his own things to do, he deliberately trained himself to turn a deaf ear to those voices, and the results of these years of training are satisfactory to him.

The strongman clan can't be dual-minded, as long as they focus on one thing, other things can be automatically ignored.

But the heavy footsteps had followed him all the way. Turning a deaf ear does not necessarily mean turning a blind eye to potential dangers.

Xu Yingdong turned sideways slightly, let his nose inhale, he smelled a smell of rust, a bit like a wallpaper knife that has not been taken care of for a long time, and then ...... There is also the smell of blood on the knife!

Without looking back, the young blood doctor could tell by the sound of footsteps and the smell that he was followed by a strong, armed man who had probably been murdered!

Lei Yuanzheng didn't think much about it, he followed Xu Yingdong safely, and when he saw the other party enter the apartment, he also entered.

Xu Yingdong judged the distance between the other party and himself according to the footsteps, and at this time an elevator arrived, he got into the elevator and pressed the 3rd floor first, and then the 6th floor.

Lei Yuanzheng took a step too slow and didn't get on the elevator, he stared at the numbers on the screen, stopped on the 3rd floor, and then went up to the 6th floor, according to the full occupancy of this apartment, it may be that there are people on the 3rd floor, so the target is on the 6th floor. He walked into another elevator that arrived, pressed 6 directly, and after thinking about it, he pressed 3 again.

Xu Yingdong was indeed on the 6th floor, and he wasn't sure if the person was following him at this time, so he stood in the straight and deep corridor on the 6th floor and listened intently.

Another elevator opened on the 3rd floor, and the footsteps of the big man walked out of the elevator, and the footsteps lingered on the 3rd floor, probably because he was exploring the corridor, and the footsteps returned to the elevator and ran upstairs!

As the elevator approached, Xu Yingdong smelled the smell of blood again. Now he can confirm that the man is stalking him!

Xu Yingdong walked up the stairs to the fifth floor, heavy footsteps sounded overhead, and the people who followed him seemed to be searching. Then the man also walked towards the stairs.

Xu Yingdong once again began to calculate the distance between the other party and himself based on the sound and smell, and he did not escape from the stairs again, but steadily intercepted an upward elevator and went up to the 6th floor.

The big guy ran from the stairs to the 5th floor—

The big man seemed a little confused, and he returned to the stairs and began to walk slowly in small steps, presumably looking for his footprints-

The big guy followed the footprints to the elevator again, but he obviously didn't know whether to get on or off.

Xu Yingdong found out the location of Lei Yuanzheng from the air, took an elevator that was out of place with him to the ground floor, and left the apartment quickly.
