Han Daring just thought of the word policeman, looked at the hand that pinched the brim of the hat, and realized that after pressing the clothes just now, there was a round mark on the palm, which was the same size as the mark on Hua Si'er's hand, but it was caused by the opening on his police uniform, and the print on the button was vaguely similar to the pattern of the circular mark on Hua Si'er's hand.

Isn't this a confirmation from the side, the message left by Hua Si'er! The killer masked man is actually a police officer.

From such a high position on the roof, it is not easy for Hua Si'er to rely on a small mirror to see the human appearance of the mask. If the masked man was a police officer, then he must have taken off his robe to bandage his wounds, and then quickly changed into police clothes and prepared to leave.

At this time, Hua Si'er was found, and when he was dragged off the roof, Hua Si'er casually removed a button from the masked man's police uniform and clutched it in his hand, so the button traces were printed on the palm, but it was later discovered by the masked man and snatched the button from his hand.

When the Zhenxian Temple was broken before he got off work, the director of the department gave a temporary notice that all the police officers of the headquarters must report for duty before 5 o'clock in the morning of the next day, saying that important officials from the Nanjing government were coming to inspect, and everyone must report before dawn to arrange tasks. In fact, in order to wait for Han Dadaer and others to break the True Immortal Temple at night, they arranged for the police to raid the True Immortal Temple before dawn.

That night, after the True Immortal Temple was smashed, the director of the hall mobilized police forces to check the True Immortal Temple in various important places, and gathered police forces before dawn to raid the True Immortal Temple. If the masked man was really a police officer from the main hall, after the True Immortal Temple was broken, he would definitely think that the task in the early morning of the next day was to raid the True Immortal Temple. So after he bandaged the wound at the foothold, he immediately changed into a police uniform and had to leave to report to the main hall immediately, and there was no time to deal with Hua Si'er's body.

And he must know that Tianjin Wei has set up cards everywhere, and it is impossible to escape with Hua Si'er's corpse, so he faked the scene and left the corpse in the small bungalow.

It's a pity that because of Zhu Tianfei's death that night, Han Da'er was overly sad and didn't pay attention to other things at all, even if someone in the police department of the headquarters had white ash on their clothes and a sloping roof, or their arms were injured, he didn't notice it at all.

Han Daring just thought about this, but quickly dispelled this idea again, and said secretly, no. The people of the Sanyang Sect have pigeon blood cinnabar tattoos on their bodies, and after breaking the true immortal view, the headquarters strictly checked it from top to bottom, and everyone poured wine to check it, and indeed found out a few traitors of the Sanyang Sect.

But among the few people who were found out, if there was really a master like the masked man, how could he let the police lock it, and he could completely stomp his feet into the room, even Lu Songtao and a few people in the True Immortal Temple were present, and the peripheral police were there, they couldn't stop him, and if he really moved, how could he be easily caught.

There is also a possibility that the masked man is indeed a policeman, but not a police officer from the main office, but a police officer from the various administrative offices, or a police officer from the night patrol and horse patrol. Hua Si'er wanders the streets all day long, and the policemen he knows are not only Han Daringer, but almost all the policemen patrolling the streets are familiar.

Moreover, it is not only the police who wear large-brimmed hats and uniforms, but also those who serve as soldiers in the army, including postmen, who are also treated with large-brimmed hats and uniforms. It seems a bit arbitrary to infer that it is a police officer based on the large-brimmed hat and uniform alone.

But if this masked man is indeed a policeman, and he is also a policeman from the General Hall, then the news of Yucong was released before, and he ambushed people at home, arranged traps, and wanted to invite you into the urn, but in the end he found nothing, so it makes sense.

Because the masked man is lurking in the main hall, and he is in the police in charge of the ambush, the plan to catch the turtle in the urn is just in vain.

Han Da'er made up his mind and planned to screen carefully in the main hall again. Since the masked man has an injury on his left arm, let Mei ask the director of the department to make up a name and check the arm of every policeman in the headquarters from top to bottom.

Although it has been more than a month since the masked man was injured, the gunshot wound has long healed, but there will always be a scar, as long as you check the new wound on the arm, regardless of whether it is a gunshot wound or an abrasion, there is a suspicion, first control it, and then carefully investigate.

Although the masked man has an old voice and a gray beard under the mask, it should be a means to hide people's ears and purposes, just imagine a long beard, dangling in the police pile all day long, can it not be noticeable, so the masked man may not be really an old man.

In this way, the identity of the masked man is even more likely. But first of all, the director of the hall and Mei can't be masked people. They were very clear about the deployment of the True Immortal Temple, and the director of the hall was mobilizing the staff to play the card at that time, and Mei was in the True Immortal Temple, and the mask man had appeared at the same time.

Secondly, You Fei, Zhang Biao, and Fan Tong are not very likely. Earlier, because Han Daring lied that the ghost ball was handed over to the main hall and was collected in the evidence room, it attracted the mask man to visit the main hall at night.

It happened that You Fei and Zhang Biao were patrolling the main hall that day, and You Fei was also injured by the masked man. Although You Fei pretended to be sick and suffered an internal injury, it was true that he had a dislocated shoulder and a cracked bone. If it weren't for the ghost work ball that the masked man was aiming at in the evidence room at that time, and he was unwilling to entangle more, You Fei and Zhang Biao might have died in the hands of the masked man.

Besides, You Fei, Zhang Biao and Fan Tong are all different from the masked people. Zhang Biao is too tall and strong, Fan Tong is too short, and You Fei's height and body are shorter than the mask man, and his body is also thinner. So these three people are unlikely.

Others are like Wang Zhen's thin and monkey race, Liu Fang is as fat as Dunzi, but Li Huan's height and body shape are not much different from that of the masked man.

Then there are some old fritters in the main hall, as well as Feng Qin and Wu Shou in the reserve team, who are similar in size to the mask man, and these people must be carefully investigated.

Hua Si'er's parents died early, there was no third brother and no fourth brother, he was alone, and several relatives in his early years had long since stopped moving. Now there are no close people except for a few good ones, and the only one that is good is the nose.

Han Daring informed Hua Si'er of Hua Si'er's death, he was afraid that if he told him the truth, he would be involved and would give his life. After all, Nose still has a few younger siblings to support. So I only told him that it was an accidental death.

Nose is also a person with a cleaner face, so he can only hastily collect Hua Si'er's corpse, Han Da'er paid some money for funeral expenses, and buried him outside Xiguan and set up a grave bag.

Although Hua Si'er has a bad character, usually fools around on the street, and occasionally blackmails Lao Tan'er and his wife for money, but he has never really harmed anyone, at most he is blind with his little daughter-in-law. So his death, Han Da'er was not very happy in his heart. In any case, Hua Si'er also wanted to find out the identity of the masked man, and he was killed.

Han Da'er secretly made up his mind that he must find out the identity of the masked man and give Hua Si'er and his uncle Zhu Tianfei an explanation.

He thought that he would first be in the same breath as Mei and the director of the hall, and check again inside the main hall to see if there were any injuries on everyone's left arm. But in addition to the director of the hall, there are also deputy directors and several other leaders, who take the liberty of asking people to open their clothes to check themselves, which is probably enough.

Han Daring thought about it a little and felt that in the name of a collective physical examination, it was a good way for everyone to secretly investigate when they were undressed during the physical examination.

In the old days, unlike now, there was no concept of physical examination at that time, only some sailors who went to the sea, before boarding the ship, they had to do a simple physical examination to see if there were any infectious diseases, otherwise they would be at sea for as little as a month or two, and more than half a year, and the ship on which they died was relatively light, and if the whole ship was infected, the vast sea, but they all had to die with a piece.

Now that I suddenly arrange a medical check-up, on the one hand, it seems a bit abrupt, and on the other hand, I don't know which hospital to look for. So Han Daring found Mei Ruohong to discuss, wanting Mei Ruohong to come forward and conduct a police physical examination or something in the name of Bath's laboratory.

Mei Ruohong saw Han Daring returning to Tianjin Wei, and it seemed that the haze above her head had also dissipated, and she was more relieved. But when he said that he wanted the Pasteur laboratory to arrange a physical examination, he said coldly:

"I'm just a laboratory technician, do you think Pasteur is my family's driver? Besides, at this time, the chemical laboratory, not a hospital, where does it come from to give people the qualification for physical examination! ”

Han Daring was also a little embarrassed, the laboratory was not good, or he would go to the epidemic prevention hospital to find Lao Su to try, but Lao Su only took care of the autopsy, the epidemic prevention hospital has the normal management of the medical system, and he knows the director of the epidemic prevention hospital and most of the doctors, but the friendship is not deep, and people may not be willing to help.

If you try to find Bai Chongwei, with his relationship, you should be able to find a suitable hospital, but I heard him say that he has a good relationship with the director and doctors of Madaifu Hospital, and it should not be difficult for him to arrange a physical examination, anyway, the cost will be paid by himself, and he will not need to pay for it.

Mei Ruohong saw Han Daring thinking for a while, turned around to leave, and said:

"It's not practical to have a physical examination, but I have a way!"

Han Daring actually didn't want to take a favor, although he had saved Bai Chongwei before, and now he and he are good friends, but he always troubles people, and Han Daring feels embarrassed in his heart. Since Mei Ruohong had a way, he stepped forward to ask for advice.

Tianjin Wei had an epidemic of typhoid fever and malaria some time ago, although the Japanese colluded with the Sanyang Sect to conduct germ experiments, but in the end, they did not get any substantive evidence, so these situations were not made public.

The vaccines and special drugs seized by the True Immortal Temple used by Pasteur Laboratory were copied in batches, and the people who were infected in Tianjin were basically cured, but the people did not know the inside story and only thought it was a general infectious disease.

Mei Ruohong proposed that it is not so much about physical examination as about preventing typhoid epidemics, sampling tests, and vaccination. It just so happened that the Pasteur laboratory also wanted to conduct sampling tests on patients and ordinary people in view of the epidemic situation some time ago, so it simply chose the location in the main hall.

The police handle cases every day throughout Tianjin Health visit and investigate, contact with many people, the probability of infection is also high, there are many patients who are police officers of the General Department before, and now sampling and testing in the General Department is also targeted, compared to the sudden arrangement of physical examinations, it will not arouse suspicion.

After Mei Ruohong asked the director of the laboratory for instructions, he was quickly approved.

Han Daring also shared his thoughts with Mei Ability, Mei Ability's whole family was plagued by the Sanyang Sect before, and he had long hated the Sanyang Sect to the root of his teeth, and when he mentioned it to catch the traitor of the Sanyang Sect, it was useless for Han Daring to talk nonsense, so he quickly reported the matter to the director of the hall.

The director of the hall experienced what happened to Luo Xiaoliang last time, and this time he didn't even beat Ben'er, so he approved Han Da'er's suggestion.

In fact, he also has selfish intentions, he and the deputy director were originally a little incompatible, the relationship between the two has not been very good, the deputy director also has a lot of cronies in the main department, and he has been operating outside recently, hoping to be promoted to the central government, directly climb on his head, so he is also holding back to find an opportunity to pour some dirty water on the deputy director, maybe this is an opportunity.

Two days later, everything was ready, Mei Ruohong, two laboratory technicians from the Pasteur laboratory, and two young nurses invited from Madaifu Hospital for injections, accompanied by Han Da'er, came to the main hall.

In the main hall today, even the policemen who were on leave and sick were all called back.

The big guy heard that it was a sample survey, and maybe he had to take a shot, so he was a little resistant. But when I heard about vaccination, I immediately came to my senses. After all, when typhoid fever and malaria were epidemic before, many people who were infected with the disease returned to the West. Everyone didn't know what a vaccine was, but they only heard that it could prevent typhoid fever and malaria.

One by one, the policemen opened their arms, lifted their clothes, exposed their left arms, and underwent blood tests, while Han Daring observed secretly.

From top to bottom, everyone has checked enough, You Fei, Fan Tong, Zhang Biao and others, and even Li Huan, who is very similar to the masked man, but they didn't find that someone had a gunshot wound on his left arm. Only Lao Liu of the General Affairs Section has a large burn on his left arm, which is said to have been scalded by boiling water in his early years, and it looks like an old injury.

At this time, Han Da'er suddenly remembered that the mirror fragment found in the place where Hua Si'er's corpse was displayed, and he had another guess in his heart......
