Chapter 277

"When Professor Naduo died, the little beggar was the ghost later?" Lele recalled the scene when the ghost told his life story again, not only sighing, "he is also a poor child!"

"If so many professors don't die, maybe the Ghost won't become like that later. He hates everything except our Jiajia..." Zhang Dian looked at the atmosphere and joked.

Only Wang Yanke and song Xiaojia didn't speak. Song Xiaojia was regretting the ghost. She had a special feeling about the man, but she couldn't say what it was. In fact, it can also be said that he died in her own hands.

Wang Yanke, after a long silence, slowly said his concern: "there are two what professors say, do you know?"

Xu zhe shook his head: "this is also a problem I haven't figured out for more than 20 years. What many professors, like human prophets, said at the last moment must be very important. However, neither Lin Tao nor I guessed the answer to this problem. It may be an unsolvable mystery."

"Oh..." Wang Yanke suddenly said, "did you send someone to kill so many professors?"

Xu zhe was surprised. The girl's thinking was really quick. She could see through it so easily

"Yes, do you remember the last word commander He Gang said in my ear before he died? He explained two things. First, he washed away Lin Tao's memory. He was too impulsive, curious and reckless. He was not suitable for contacting so many state secrets. Second, he killed so many people, took his brain and studied their knowledge!"

"Sure enough, it is the cruelty of politics to kill former comrades in arms and companions for the sake of interests!" Wang Yanke said coldly.

"There is no way. Many professors who had cancer at that time refused to tell the final way to prolong human life. If he died, he would bring these secrets to the grave forever, which would be a great loss to the motherland and people, and we have no way... Moreover, once this generation of Heroes died, we would not want history to give us the next one Know how many years it will take! The only way is to take it out while his brain is still alive. When people die, there will be no personal emotions and political positions. We only extract the knowledge... "

"Did you succeed?" Wang Yanke asked with a sneer.

"It's half successful. Professor Naduo doesn't know how to shield the part about bioengineering in his memory. Maybe he forced himself to forget. However, we found the technology of biological mechanical synthesis, which is also the key to all war cats' research and development. In addition, the technology of manufacturing advanced robots like Xiaobing that can carry human consciousness is also that Many professors get it from their brains. "

"Well, whether the past is right or wrong, what happened later? Did you wash away Lin Tao's memory?" Hao Zhi didn't care about this. He wanted to hear the story and asked hurriedly.

……

Lin Tao returned to the military area command compound with a heavy heart. The people of the municipal Criminal Investigation Brigade took away the bodies of many professors for autopsy. The guards did not track the mysterious gunman, or even the shadow of the other party.

An old man in his seventies should not have any enemies. The motive of the killer is unknown, and the identity of the killer is even more suspicious. The identity of a person who has worked in a state secret unit for so many years is protected by top secret. Except for a few insiders, it is impossible for outsiders to know the true identity and appearance characteristics of those professors, Even Lin Tao used almost all his networks to find out.

In other words, someone in the military region has betrayed!

Only after the ballistic test results of the bullet come out, can we see whether the bullet belongs to the army. Besides, ordinary criminals can't get that kind of sniper weapon with micron accuracy.

Suddenly, Lin Tao thought: could it be Xu zhe who ordered people to do it?

He speculated for a while, and then leaned on his sofa and massaged his temples. It should not be Xu Zhe. He and many professors never met. Moreover, in terms of time relationship, they are colleagues. Their interests should be common. They will not and are unlikely to involve the motive of killing people

Too many things have happened recently. Lin Tao felt very tired, so he fell asleep on the sofa. Many messy dreams floated before his eyes while he was half asleep. Suddenly, an emergency telephone ring woke him up: "report to the political commissar, the autopsy analysis results of many professors have come out..."

"Oh?" Lin Tao immediately woke up, wiped his face with his hand and asked, "where's the bullet?"

The other party hesitated, and then replied in a very uncertain voice, "no bullets!"

"What?" Lin Tao stood up. The distance between the killer and the professor at that time was not too far. If it was an ultra long-range sniper rifle, the bullet could indeed fly through the body.

"What about the area near the scene of the incident? Have you searched the range in the direction of the ballistic trajectory?"

"In fact, the bullet did not penetrate so many bodies, because the back of the wheelchair blocked it. There was a plank inside the back, and the outside was wrapped with sponge and leather. Therefore, the bullet did not have much power after penetrating the back of the chair, but just shot into the body of so many professors. The bullet did not penetrate, but remained in the body!"

"Then why can't you find it?" Lin Tao didn't understand.

"We conducted a very detailed search in Professor Naduo's body, and there was no warhead left. However, we found that some blood had abnormal coagulation, that is, the blood of the human body had temperature, and it would solidify only after a certain period of cooling. The blood coagulation rate near Professor Naduo's wound was much higher than the normal rate..."

Lin Tao's eyes stared very big and muttered to himself, "ice bomb!"

"Yes, the current speculation is that the bullet warhead used by the other party is made of dry ice!"

"Impossible!" Lin Tao said. "That's just nonsense in the movie. In real life, the quality and density of ice can't be made into bullets. It's too light. Even if it can be fired, it can't cause fatal damage to the target! Have you ever seen people killed in a snowball fight?"

Indeed, when Lin Tao was studying at the military academy, he specially studied such future concept weapons because of his interest. Later, he found that ice bombs are simply impossible in reality - the density of lead used to make bullet heads is 11. 34 grams per cubic centimeter, while the density of ice is only 0. 9 grams per cubic centimeter, and the density of dry ice is 1. 5 grams cubic centimeter. Obviously, a bullet made of ice has the mass of a normal bullet and is 12 times larger than a normal bullet. 6 times. Dry ice is 7 times larger than normal bullets under the same conditions. 56 times.

It's like a pound of iron is only half a fist ball, but a pound of down can make four down jackets. Under the same quality, the volume is much larger. You can hit a dead person with an iron ball, but you can't kill a person with a down jacket.

Moreover, you have to have such a big gun or gun to launch such "huge" bullets... If it's so troublesome, you might as well find an ice pimple and throw it upstairs to kill each other.

The other end of the phone confirmed his statement, and then the technician slowly opened his mouth: "obviously, the other party's purpose is not to kill so many professors..."

"Two shots hit the heart, not to kill him?" Lin Tao was stunned.

"Those two shots were extremely accurate. They didn't hit the heart at all, but just rubbed the edge of the heart..."

"What? So many professors are still alive?"

"No, he's dead..."

Lin Tao was confused. Do you want to kill him or not? Why is it so complicated?

"Don't worry. Let me explain. As you know, ice is too light as a bullet and can't hurt people. Therefore, the other party wisely mixes water and mercury, and then freezes them into the shape of a bullet... And the density of mercury is greater than that of lead. Even if there is only half of the mercury in a bullet, it can be used as a bullet, Kill the target... "

"Then why did the other party avoid the heart?"

"I think the main purpose of the other party is, first, not to leave bullets as evidence, because the ice will melt into water, and once the ice melts, the remaining Mercury will be absorbed by the human body. Even the unabsorbed part will soon volatilize into the air. Then when we dissect the corpse, we will not find any traces of bullets... Second, the other party's purpose is not to kill on the spot Professor Naduo died. His hidden purpose is to kill him with mercury poisoning, that is, a relatively slow death... "

"You mean that Professor Naduo didn't die, but fainted?"

"Yes, the real time of death should be on the way to the hospital. In fact, if we send the patient to the hospital in time, we have a way to give first aid. However, a group of people gathered on the road suddenly and inexplicably, resulting in a traffic jam. The ambulance was delayed for a period of time. When it was sent to the hospital, we already had very serious poisoning symptoms. We are really incompetent To help... "

"Why is it so coincidence that there are people blocking the road? The area where the sanatorium is built usually has a small flow of people? Wait, in order to die slowly, it's time difference..." Lin Tao straightened his mind, that is to say, the other party didn't want to kill so many professors at that time. What's the main purpose of leaving him some time? By the way, is it to ask the last "two secrets" from so many professors?

Well, the person who can ask this last sentence must be in the ambulance! Thinking of this, Lin Tao immediately ordered: "immediately organize the police to control all those who have contacted so many professors, and there must be no leakage!"

"Yes!" the phone on the other side hung up. Lin Tao fell decadent on the sofa with a brain lawsuit. In his mind, he recalled the words that many professors said at the last moment: "two... Two..."

Two killers? One shot, one hidden in the ambulance?

Or are there two of his notes? What was in the memory he handed over to himself on his deathbed?

Lin Tao was thinking. Suddenly he heard the lock of the door ring slightly!

It's already 11:30 midnight. It's very quiet around the military region's family compound. Unless they have special work to do, most of these professional soldiers maintain good sleep habits. Because the high school where their son wants to study is far away from here, Lin Tao's wife and son live with their father-in-law on the other side of the city. Who will come at this time?

Out of a soldier's instinctive reaction, Lin Tao had a hunch that something was wrong. He knew that the more intense the reaction at this time, the more he would expose his position at the first time. With the curtains pulled, people outside could not see the house at all.

Guns! The holster and the cover were thrown on the shoe cabinet at the door when he entered the door. Lin Tao was ten steps away from the gate. He stood up as gently as possible, took his feet out of his slippers, held his breath and walked quietly towards the door

Over there, the inner lock handle of the anti-theft door is tilting bit by bit, tilting, making a slight click
