Helian Yi's last memory was not Wen Jike, which surprised me, she said that the last thing she saw was a female teacher, my first reaction at the time was An Rongyue, but I quickly dispelled this idea, Helian Yi's thinking and logic are normal, she mentioned a female teacher, it can be seen that this person is not a patient.

I even took Jiang Xinyu's photo for Helianyi to identify, she shook her head affirmatively and denied it, if Helianyi climbed into the morgue and fainted by herself, then it should be impossible to see other people in this process, right, who is the female teacher that Helianyi saw last?

Nangong Yi said that if Helian Yi had seen other people when she entered the morgue, this was obviously abnormal, and she planned to retrieve the photos of all the incumbents of Hede Medical College ten years ago for Helian Yi to identify.

Yun Duruo and Nangong Yi returned to Hede Medical College to ask Hua Guanwen for photos, and the prince and Han Yu helped deal with the follow-up of Wen Jike's case, wanting to understand this case as soon as possible, Han Yu found me and asked me how to deal with the things left by Wen Jike.

His files are all fake, and he doesn't know if he has any relatives, and he doesn't know who to hand over the items left behind, just thinking about this problem, the prince asked me and Han Yu to go to the evidence room, and I was a little surprised to see the prince's expression, he has always been a calm person, and there must be something unusual with such a reaction.

The prince spread a complete architectural drawing on the table, which he found from the book when he was cleaning up the things found in Wen Jike's room, Wen Jike's case since he detonated the explosive and died on the spot, I haven't paid attention to it, I have seen this architectural drawing before, but that one is much smaller than this, it was hand-drawn by Wen Jike himself, and the one on the table is the most complete professional drawing of the teaching building.

Unlike the sketch, the architectural drawings of this school building are marked in red in more places, and each place is densely annotated with calculations and figures for the amount of explosives planted.

"I went through all the books I brought back from the dormitory, and this booklet was hidden among the many books." The prince handed us a small booklet, which must have been read many times. "This is all about the information about the blasting, it seems that Wen Jike wants to blow up the teaching building is definitely not a matter of one or two days, he has been planning for a long time, if the teaching building is blown up after repeated arguments, and the results and methods have been obtained."

I looked at the architectural drawings on the table and took a deep breath, although I didn't know anything about architecture, but judging from the red marks on the drawings, if there were enough explosives, once Wen Jike detonated the teaching building, it would be razed to the ground in an instant.

"Fortunately, it was discovered early, if you wait for Wen Jike to prepare properly, the consequences will be really unimaginable." I said to them with trepidation. "But until now, I still can't understand and think about Wen Jike's motive for blowing up the teaching building."

"It seems that we all underestimated Wen Jike." The prince calmly placed a piece of paper in front of us. "This is also found in the Wenjike book, you must not guess what is written on it."

Seeing the prince's solemn expression, Han Yu took it and looked at it for a while, and then his mouth slowly began to open, looked at us dumbfounded, and pushed the piece of paper in front of me.

"Wen Jike has already prepared explosives!"

I looked at the paper that the prince found in shock, and Han Yu's reaction was the same, and after reading it, I was shocked and didn't know what to say, this was a purchase list, and my eyes fell on one of them.

Nitroglycerine!

This is the main raw material that can make high-explosive performance explosives, which is completely incomparable to the ammonium nitrate explosives made by Wen Jike at the end, and the power is huge beyond imagination, and I also saw detonators at the back of this list, and the number is amazing!

Wen Jike planned to use a detonator to detonate nitroglycerin explosives, which would have been a breeze to blow up a school building.

What makes me even more frightened is that each item in this procurement list is ticked with a red pen, which shows that Wen Jike has already prepared these materials, and many of the raw materials in the list are extremely strictly controlled, and the time it takes for Wen Jike to prepare them all must not be a matter of one or two days.

"Wen Jike secretly purchased so many dangerous explosives raw materials, but he didn't find it when he searched his dormitory." Han Yu said with a grim frown. "Where will Wen Jike hide these things, no matter what, it is very dangerous for these things to exist."

Once again, my eyes fell on the architectural drawings on the table, and I was shocked that the places marked in red were the weakest parts of the school building, but they were also all in the basement where few people would go.

Thinking of this, the corners of my mouth squirmed, put away the drawings on the table, and the prince and Han Yu hurriedly went to Hede Medical College, and asked the police to immediately notify the bomb disposal team to rush to meet us.

Seeing Nangong Yi and Yun Duruo at Hede Medical College, and learning that Wen Jike had purchased such an astonishing amount of explosives raw materials, their reaction was as shocked as when we learned the news, Nangong Yi immediately asked Hua Guanwen to evacuate the students in the teaching building immediately, and after making sure that there was no one in the teaching building, the bomb disposal team that arrived entered the building with the drawings we provided.

I hope the conjecture is wrong, otherwise this hidden danger is likely to be triggered at any time, and we all retreat to the complete area where the school building will not be affected by the collapse, and the bomb disposal team that enters is always in touch with the outside world by walkie-talkie.

"The first suspected bomb item was found on the bottom beam of the building." The report of the bomb disposal team came from the walkie-talkie, and I took a deep breath to see that my conjecture was correct, and Wen Jike had already arranged these explosives under the teaching building.

After more than ten hours of hard work by the bomb disposal team, in the middle of the night the news that all the explosives were safely dismantled came from the walkie-talkie, and we breathed a long sigh of relief, although Jiang Xinyu next to her had been silent, but I saw her anxiously rubbing her hands nervously, Hua Guanwen kept wiping the sweat on her forehead, and said thank you to us.

After the explosives were dismantled, the bomb disposal team inside re-inspected the entire school building, and finally confirmed that it was complete, we were notified that we could enter, and the experts of the bomb disposal team led us to the place marked in red on the drawings, and we were shocked to find that Wen Jike had hidden the assembled explosives in inconspicuous debris, these explosives were equipped with timed detonation devices, and the fuses of the explosives had been installed and could be detonated at any time when they were found.

Experts say that the initial estimate of the yield of these explosives, if they were detonated at the same time, the school building we are standing on today would be in ruins in an instant.

"Since Wen Jike has prepared everything a long time ago, since he can sneak back to the chemistry laboratory, he has every chance and time to detonate these explosives, but why did he reassemble the ammonium nitrate explosives that are not very powerful?" Yun Duruo asked in surprise.

This is also something I haven't figured out until now, and there is no one more familiar with the explosives than the experts of the bomb disposal team, and I took them to the place where Wen Jike hijacked us, and where Wen Jike was killed on the spot.

"It was here that the murderer detonated the explosives, and according to his thoughts at the time, his purpose was to blow up the building." I pointed to the place where Wen Jike died and said to the experts. "Will the blast damage the building here?"

The experts of the bomb disposal team surveyed the scene and asked us in detail about the explosives used by Wen Jike at that time, and looked at us with great confusion.

"The amount of explosives on the assailant's body, if you say, has almost no effect on the main body of the building, if there is any loss, it is close to the exterior wall of the school building, and if the explosive yield is sufficient, it will cause damage to the exterior wall of the building, but at best it will cause cracks in the exterior wall of the building."

I frowned, judging from Wen Jike's preparations, he is actually an extremely thoughtful person, since it obviously has no effect, why should he do this.

"If the murderer wanted to blow up the building, he could have detonated the nitroglycerin explosives that had been installed, and he obviously did more than this here, judging from the nitroglycerin explosives assembled by the murderer, he had mastered the technology of making high explosives, and at the same time controlled the amount of explosives just right." The expert looked at us and said with certainty. "He's perfectly capable of blowing up the building, and I don't think it's a mistake for him to detonate the explosives here, it's clear that the killer had other intentions in doing so."

I was about to ask the question again, but the expert asked where the hostage who was taken by Wen Jike at the time was standing when the explosives exploded, and I told the expert that Yun Duruo and I were at the scene at the time and witnessed everything, and retreated to the place where they were standing at that time.

"The murderer was detonated here?" The expert walked to the place where there were obvious traces of the explosion, looked at me and Yun Duruo and asked in surprise.

Yun Duruo and I both nodded, and the expert frowned as if he was thinking about something, and then took a step, each step of the same size, and walked in front of us from the place where Wen Jike exploded, and I realized that he was measuring the distance, and when he stood in front of us, his brow furrowed even deeper.

"The murderer told you to retreat here?"

Yun Duruo and I nodded blankly.

"That's a little weird." Experts go back and forth at the point of the explosion and the distance between us, talking to themselves in doubt.

"What's wrong?" Yun Duruo asked curiously.

"The murderer clearly knows that you are standing beyond the reach of the explosion, and the murderer ......" the expert hesitated, clearly puzzled. Based on the extent to which the perpetrator knows the yield of explosives, he should be able to measure the lethality and scope of the explosives...... The murderer doesn't want to hurt you at all. ”

Wen Jike didn't think about ......, "I looked at the bomb disposal expert in surprise." So what did he bring us here to detonate explosives? ”

"He used ammonium nitrate explosives, which were extremely unstable and easy to detonate, and the murderer had every chance to detonate himself in a dead corner behind the wall, but he retreated to the range of a sniper, and he didn't need to borrow the impact of a bullet to detonate the explosive, and the only reasonable explanation for his doing so was ...... The murderer fears that the explosion will hurt you if he gets too close, so he steps back to calculate the safest distance for you. ”

……

I was stunned and speechless for a long time, Wen Jike did everything possible to hold me and Yun Duruo hostage here, I always thought that he was planning to use us to accompany the burial, since he never thought of killing us, then what did he want to bring us here for.

Do you want us to know that he is not dumb, and let us talk to him......

Talk!

I suddenly remembered what Wen Jike said before he died, and the last sentence was.

Since you believe what I say, then I will prove the truth to you with facts, and I hope that my blood will not be shed in vain......

I read this sentence carefully and repeatedly in my mouth, Wen Jike seemed to have been emphasizing to me and Yun Duruo that what the eyes see may not be true, and the facts are the best way to prove the truth, but often the facts are written in blood.

Blood!

I frowned and slowly walked towards the corner of the wall that Wen Jike leaned on before he died, it was a mess after it was detonated, it had not been cleaned up, the ruins and broken walls were piled up messily, and there were red blood stains on the ground that Wen Jike left, I squatted in the corner of the wall where Wen Jike used to sit, and began to clean up the stones covering it.

The moment I removed the last piece of mottled and peeling wall skin, the corners of my mouth involuntarily squirmed, Wen Jike's blood has been spreading here, there are some black lines under the dark red bloodstains, I remember that Wen Jike sat here and smoked before he died, it was written with cigarette butts, I half-knelt on the ground to blow off the dust on the ground, and a line of numbers appeared in front of my eyes.
