Chapter 152

In the late autumn of September, it's cool.

No matter inside or within a kilometer outside the University, there are lights everywhere, just like in the daytime.

It's just -

not all the darkness can be lit up. After all, the night is night, and the darkness is its original appearance. Just like the classified people, it is usually the killers who know the killers.

In the night, a shadow that can't tell whether it's a human or a ghost is approaching the campus of Haida University. This shadow is really more like a ghost than a person, because every time he stays in the dark, the light can't shine. And every time he left the darkness, that is, when he disappeared, there was no shadow, no sound, nothing, as if he had never appeared in the light.

After the shadow flashed about a dozen times in the distance of one kilometer, a breeze blew and dropped several leaves of a banyan tree in Haida campus. When the leaves fell, a person appeared on the tree --

the black baseball cap was very low, the black mask covered most of the face, the black windbreaker, black trousers and black shoes And a pair of black gloves. In addition to the strange red light flashing in the black eyes, this man has almost completely integrated into the darkness -

Liu Yanbo.

A better person to live in the night, because he is the darkness.

Haida school covers an area of about 2.44 million square meters, with a building area of about 2 million square meters. Now, the lights in every building here are on. If you don't get general information, you can't find the location of the gangster in a short time.

Liu Yanbo is not a ghost. He can't find the whole campus of Haida in about two hours, which is the main reason why he risks being suspected to find pan Yuyi.

On the banyan tree, Liu Yanbo didn't rush to the library where the hostages were held. He closed his eyes, held his breath, and listened quietly to the sound of the wind, the sound of falling leaves and grass, and the singing of insects and birds

After confirming that there was no other living person within tens of meters around, Liu Yanbo slowly opened his eyes and disappeared on the banyan tree. When he reappeared, he was already in the shadow behind a rockery.

Disappear Appear Disappear

After about ten minutes, Liu Yanbo was already in the library when he reappeared. His most important task now is to determine whether his guess is correct.

If the hostages have been held separately, it will be a lot more difficult to rescue.

Probably the gangsters were short of manpower. Except for the screening room on the second floor, Liu Yanbo basically looked through the whole library, but he didn't see any human figures.

It's good news and bad news that there are no gangsters at the gate of the screening room.

The good news is that Liu Yanbo can easily get closer to it. The bad news is that it looks more and more like a trap, or bait.

There is only one door for people to get in and out of the projection room, but there are air windows on the door.

Liu Yanbo is like a gecko. He sticks his whole body on the ceiling and looks at the situation in the projection room through the air window.

He was right.

there were only 30 or 40 students in the screening room, and only six criminals were on guard.

Liu Yanbo did not break in, but did not immediately leave to find where the other hostages were held.

The sound insulation effect of this screening room is very good, but there is still a crack in the door. Liu Yanbo has excellent hearing. After lying on the ceiling for about two minutes, he hears a rule that the gangster has a walkie talkie, which rings once every five seconds, a total of seven times. Each time, different people are reporting "safety".

When the walkie talkie rings seven times, it means that at least seven groups of people are hiding in different positions. In addition, six gangsters in the screening room are counted as a group, which is eight groups in total.

Liu Yanbo looked at his watch and determined the time.

It's 10:33 p.m., less than an hour and a half from the four hours when the city officials agreed with the gangsters. He knew that he had to find the 25 gangsters who had been divided into eight groups as soon as possible.

According to pan Yuyi's intelligence, the positions of five groups of people in the eight groups have been determined. It is only necessary to find the other three groups.

Fortunately -

Liu Yanbo is always good at tracking people. It took him about 20 minutes to find the other three groups.

There is a lotus pond behind the library. There is a birch forest on the left side of the pool. There is a group of two hiding in a pavilion in this forest, with two hostages tied with hands and feet and mouth blocked.

About 30 meters south of the birch forest, there is a small auditorium, in which there are seven gangsters guarding most of the remaining hostages. Lin Xue is locked here.

About 20 meters to the north of the auditorium, there is a five story teaching building. On the top of the building, there is also a group of two with two hostages.

……

There are 12 members in the six two person groups. There are six gangsters and seven gangsters in the two places where the hostages are held, that is, 13 guards.Liu Yan, I've found twenty-five gangsters by myself.

Out of selfishness, Liu Yanbo decided to set the small auditorium as the first target.

It was probably for the convenience of six two person team operation support hidden in the outdoor. Although all the buildings in the school were on, there were not a few street lamps on the campus, which made Liu Yanbo's action more convenient.

Under the cover of the night, Liu Yanbo once again touches the small auditorium where Lin Xue is held.

Liu Yanbo shrinks his body in the drainage ditch in front of the auditorium. Before taking action, he must ensure that everything will develop according to his expected direction, without any mistakes.

In September, the weather has already turned cool.

The water in the ditch is also very cold, and the taste is not very good, but Liu Yanbo just lies in it, letting the cold water wet his clothes and prick his skin

He is waiting for people in the auditorium to say that sentence in English: safety. At the same time, he is doing the final calculation.

If the gangsters in the auditorium are numbered as the first group, then the two snipers lying on the fifth floor of the building are the second group, and those in the birch woods are the third group In the projection room is group eight.

From the first group to the end of the eighth group, it will take at least 40 seconds for the gangsters to finish this round. From group 8 to group 1, this is another round, or about 40 seconds

This method is very careful, but also the biggest flaw, because it is too regular.

According to this method, after the first group of gangsters reported safety once, they had to wait at least 80 seconds before it was their turn to report again. However, it is not without benefit for them to report security in this regular order. For example, when the seventh group finishes reporting, it is the eighth group, and the eighth group is the seventh group. That is to say, when solving the two groups, it must be completed within 10 seconds. Once exceeded, all the hostages in the projection room will die.

However, the shortest distance between the two buildings in the second group is the shortest distance between the second and the seventh floor.
