Chapter 152: Ten seconds to determine success

In late autumn in September, Tianliang killed.
Whether it is inside the Hai University or within a kilometer away from the school, there are bright lights everywhere, as if it is day and night.
Just--
Not all darkness can be lighted up, night is ultimately night, darkness is its original appearance, just like the people who are classified, understand the killer is usually the killer.
In the night, a shadow that could not tell whether it was a man or a ghost was reaching the offshore campus quickly. This shadow was really more like a ghost than a human, because every time he settled, he was in a deep darkness where the light could not 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 this shadow flashed about a dozen times within a distance of one kilometer, a breeze blew through and dropped a few leaves of a banyan tree in the campus of Haida University. When the leaves fell, a tree suddenly appeared on the tree. people--
The black baseball cap is very low, the black mask covers most of the face, the black trench coat, black pants and black shoes, and a pair of black gloves, except for the strange red eyes flashing strange red Outside of the light, this person has almost completely merged into the darkness—
Liu Yanbo.
A person who is more suitable for living in the night, because he is dark.
The University of Haitian covers an area of ​​about 2.44 million square meters, with a construction area of ​​about 2 million square meters, and now the lights in every building here are on. If you do n’t get general information, you ca n’t get it in a short time. Find the hidden location of the gangster.
Liu Yanbo is not a ghost. He can't search the entire Haida campus in about two hours, which is the main reason why he took the risk of being suspected to find Pan Yuyi.
On the banyan tree, Liu Yanbo did not hurry to enter the library where the hostage was held. He closed his eyes, held his breath, and listened quietly to the surrounding movements—
There is the sound of wind, there is also the sound of leaves and grass moving, and the words of insects ...
After confirming that there were no other living people within tens of meters, Liu Yanbo slowly opened his eyes and disappeared on this 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 appeared again. His most important task now is to determine whether his guess is correct.
If the hostages were really guarded separately, it would be a lot more difficult to rescue.
Probably the gangsters were understaffed. Except for the projection room on the second floor, Liu Yanbo basically read the entire library, but he didn't even see one.
There is no gangster guarding the entrance of the projection room. This is good news and bad news.
The good news is that Liu Yanbo can move closer to it. The bad news is that it really looks more and more like a trap, or bait.
There is only one door in the projection room for people to enter and exit, but there is a transom on the door.
Liu Yanbo was like a gecko, he was all attached to the ceiling, and through the louver, he looked at the situation in the projection room.
He really guessed right--
There are only thirty or forty students in this screening room, and there are only six guards.
Liu Yanbo did not break in, but did not immediately leave to look for other hostages.
The soundproofing effect of this projection room is very good, but after all, there is still a door gap. Liu Yanbo ’s hearing is excellent. After lying on the ceiling for about two minutes, he heard a pattern. It will ring once every five seconds, seven times in total, and each time it rings, a different person is reporting "safety."
The intercom sounded seven times, which means that at least seven groups of people were hidden in different positions. Together with the six gangsters in this projection room, there were eight groups.
Liu Yanbo glanced at his watch to determine the time.
It was 10:33 in the evening, and the four hours away from the city officials and the gangsters said that there were only less than one and a half hours left. He knew he had to find these 25 gangsters who had been scattered into eight groups as soon as possible. .
According to Pan Yuyi's information, the position of five of the eight groups of people has been determined, and only need to find the other three groups of people.
Fortunately--
Liu Yanbo's ability to track and find people has always been good. It took about 20 minutes, and the other three groups of people were found by him one by one.
There is a lotus pond behind the library. There is a birch forest on the left side of the lotus pond. There is a two-person team hiding in a pavilion in the woods, carrying two hostages with their hands and feet blocked.
There is a small auditorium about 30 meters south of the birch forest. There are seven gangsters watching most of the remaining hostages, and Lin Xue is imprisoned here.
The auditorium is a five-story teaching building 20 meters north of NATO. There is also a two-person team on the top of the building, also with two hostages.
……
The six two-person group is twelve, and the two places where the hostages are held are six gangsters and seven gangsters, that is, thirteen guards.
Twenty-five gangsters have been found. Liu Yanbo knows that it is time for him to prepare.
Out of selfishness, Liu Yanbo decided to make that small auditorium the first goal.
Probably to facilitate the action support of the six two-person group hidden in the outdoor. Although all the buildings in the school are lit, the street lights in the campus are not lit, which makes Liu Yanbo's action convenient. a lot of.
Through the cover of the night, Liu Yanbo touched again to the small auditorium where Lin Xue was held.
Liu Yanbo shrank his body in the drainage ditch in front of the auditorium. Before acting, he must ensure that everything will develop in the direction he expected, and there should be no loss.
In September, the weather has already turned cold.
The water in the ditch is also very cool, and the taste is not very good, but Liu Yanbo is lying there motionless, letting the cold running water infiltrate the clothes and sting the skin ...
He was waiting, and the people in the auditorium said that in English: safety. He is also doing the final calculation.
If the gangsters in the auditorium are numbered as the first group, then the two snipers lying on the five-story building are the second group, and the third group in the birch forest ... the eighth group in the screening room.
Gangsters start from the first group and end to the eighth group. This round takes at least 40 seconds. From the eighth group to the end of the first group, this is another round, or about forty seconds ...
This method is very meticulous, but it is also the biggest flaw, because it is too regular.
According to this report method, after the first group of gangsters reported safety once, they had to wait at least eighty seconds before their turn to report the second time. However, it is not without benefits for them to report safety in this regular order. For example, after the seventh group is reported, it is the eighth group, and after the eighth group is reported, it is the seventh group, which means that when solving these two groups , Must be completed within ten seconds, once exceeded, all the hostages in the screening room will die.
The distance between the seventh group and the eighth group is the closest, the horizontal distance is only about ten meters, but these two groups are also staying in two different buildings, one group is on the second floor of the library, and the other group is in another. The fifteenth floor of a building, the shortest time to solve these two groups, but the most difficult-
Ten seconds to determine success or failure.
