A cold light flashed.

"Ahh

Bai Wenyu was pressing his right shoulder, he curled up, as if there was a weight on his shoulder, which pressed him so that he couldn't stand upright, he was sweating like rain, his face was red, his breathing was short, and then he began to twitch uncontrollably.

"What is this?"

Mr. Security instinctively took two steps back, clutching the spear in his hand, as if he could still control the situation as long as he had it in his hand.

Ten seconds ago, when he thought he could control the whole situation, he made an important suggestion: "Is it a murderer, find someone to take a look at her desk in the classroom, don't you know!" ”

Li Wutong said: "I'll go!" ”

"No, I'll go!" Bai Wenyu said, "I don't believe Wenwen will be a murderer!" ”

How could Mr. Bao let Li Wutong out of sight, Captain Xu was downstairs, it was not good to give up all his previous efforts.

"Let's go with Bai!" Mr. Bao held a spear and pointed it at Li Wutong and Wu Tongguang.

Bai Wenyu turned around and was about to walk outside the lounge.

Li Wutong first took pity on him for being coerced by Xu Bohao, and at this moment he was repeatedly blinded by him, she had a strong temper, and was about to attack, and said: "This girl has put up with you for a long time, but I'm afraid that you can't control this burning stick......"

Before Li Wutong's words fell, Mr. Bao really couldn't control the scene, and with Bai Wenyu's scream, it meant that the situation had changed.

Bai Wenyu couldn't leave the lounge.

Wu Tongguang and Li Wutong looked at each other like torches, and they could see that it was Situ Wenwen on the side who suddenly slapped Bai Wenyu on the shoulder. A few seconds later, Bai Wenyu changed from a violent convulsion to a stop convulsion, and he was dying.

The people in the field were taken aback, Mr. Bao was already standing at the door, and at this moment he instinctively took two steps back and exposed the door, and the rest of the people flashed to the four corners of the room, Wu Tongguang and Li Wutong immediately became vigilant - what is so powerful.

I saw that Situ Wenwen's expression remained unchanged, and she still said coldly: "Classmate Bai, what's wrong with you?" ”

She asked very ordinarily, as if it was none of her business, Bai Wenyu probably didn't even think that Situ Wenwen, who he had always had a crush on, would take his life.

Another "Situ".

"Y-What are you doing?" Mr. Bao raised his gun and aimed it at Situ Wenwen. Bai Wenyu died violently, and the closest to Situ Wenwen was Mr. Security at the door, and he said in a trembling voice: "Don't come here!" ”

Xu Zhihan and Wang Nianru were so frightened that they hid in the corner. And Wu Tongguang and Li Wutong, who were in the innermost part of the room, became the people farthest away from Situ Wenwen.

"Watch out for her hands." Wu Tongguang shouted, leaning forward, he wanted to rescue.

"Ahh

"What is this?" The sight frightened Mr. Guard, and his wrists fluttered on their own, and even the spear fell to the ground. The tremor was accompanied by a heart-rending pain, which then spread from his wrist to his arm, and from his arm to his shoulder, and he could no longer bear it anymore and fell to the ground. In a short time, he should be in the same situation as Bai Wenyu.

Situ Wenwen poisoned the two of them one after another, and was about to walk out of the lounge door quickly, presumably to return to retrieve the things he had hidden. Who is the murderer has been revealed.

"Poisoned!" Li Wutong thought to himself: "It's so poisonous." She shouted loudly: "Wu Tongguang be careful! ”

Those who are accustomed to poison must not be hard-handed. Situ Wenwen must be poor, if she is as strong as Situ Jing, she doesn't need to use poison as an aid. But the power of such a poison is something Wu Tongguang has never seen.

Wu Tongguang didn't dare to be careless, tore off half of his sleeve, wrapped his right hand, and grabbed Situ Wenwen's shoulder hard, hoping to capture her in one fell swoop.

As soon as Situ Wenwen turned around, she returned her hand with a palm, and she was facing Wu Tongguang's approach. Wu Tongguang fixed his eyes and saw that Situ Wenwen was wearing a copper and iron ring on the index finger of his right palm, and there was a small needle prick on the ring, although this needle was small, it was like the tooth of a poisonous snake, which could easily devour people's lives.

Wu Tongguang didn't dare to take her shot hard, first avoided her edge, and then walked around her, frequently making tentative shots, wanting to win from behind. Situ Wenwen was not in a hurry, and her face still had that expression of not eating the fireworks of the world. Her body also moved with Wu Tongguang, a pair of young eyes stared at Wu Tongguang, as long as Wu Tongguang's body paused slightly, the poisonous snake teeth on her fingers would jump out!

Li Wutong and Wu Tongguang have a deep tacit understanding and know Wu Tongguang's intentions. Wu Tongguang's fight, even if he doesn't win, he will definitely be able to drag Situ Wenwen down. And what Li Wutong has to do now is to take a break and find the diary left by Lei Yin!

She quickly dodged out and ran all the way through the long hallway of the school building, the gray-white walls on both sides of the corridor had a bit of history, and the sunlight shone in at one end of the corridor. She could only hear her own heartbeat and breathing, and she knew that Wu Tongguang's judgment had always been very accurate, so she must have made something when she ran into Situ Wenwen's classroom.

Li Qingfeng has been sacrificed for so long. Tracking all the way from the train to here, Wu and Li are already physically and mentally exhausted, and now the diary left by Li Qingfeng is in front of them!

The mother copy of "Guiyan" is right in front of you!

Li Wutong couldn't hold back the excitement in her heart, she slammed open the classroom door, the classroom was empty, there was still chalk handwriting on the blackboard of the classroom that Professor Chu had not completely erased after the lecture, the orientation of the classroom was not very good, half of the area was shrouded in shadows, and the other half was shining under the sunlight, dust and fine debris floated in the air, like a thin layer of fog.

She found Situ Wenwen's seat, where there was a desk with a big butterfly padlock, the lock was an ordinary lock, the desk was an unusual desk, just because it contained this important information, and this information must be related to the blood and bones on the battlefield of the two armies.

She tugged the padlock with her right hand, but it didn't open. She pulled out a steel needle and tried to open the lock through the keyhole.

Suddenly, she felt a sharp pain in the palm of her right hand.

"Ouch, not good!" Li Wutong was shocked.

This butterfly-shaped padlock is also highly poisonous!

She had seen the poison needle on Situ Wenwen's ring just now, and knew that it was terrible. She calmed down, consciously felt the touch of the palm, the numbness did not come very quickly, she calculated in her heart, the reason why the poison needle on Situ Wenwen's ring can immediately take a person's life must be related to the poison needle piercing the skin, the venom directly enters the blood and attacks extremely quickly, and at this time she touched the poison on the padlock, and its drug attack was naturally much slower.

Even so, she didn't have the ability to accurately open the padlock with a steel needle. Her hands were trembling, and she couldn't even hold the steel to aim at the keyhole, and she scolded: "The straight lady thief who kills a thousand knives." ”

Li Wutong was so resolute, she gritted her teeth, grabbed a bench, and slammed it hard against the padlock.

"Bang-" The butterfly padlock attached to the desk door was smashed to the ground.

Got it!

She almost forgot the condition of her right hand, and she took out a book-like object, and the handwriting on it was very familiar, that of the man in the gold-rimmed glasses on the train. She turned a page and saw that the header of the album had time elements such as year, month, day, weather, etc., and she flipped back casually and found that the pages were densely packed with many contents, which was the diary that Li Qingfeng left for Professor Chu to keep.

At the same time, she found that there is a very special feature of this diary that records daily life, that is, the spacing of every word in it is almost the same, the line spacing of each line is almost the same, and the spacing of each paragraph is almost the same, just like filling the blank book with uniform writing grids in advance, and then filling in the words one by one.

Li Wutong is almost certain that this diary is a cipher master. This arrangement of writing is to avoid mistakes when using the literal code, that is, numbers, to find the Chinese characters in the parent text. In order to protect this information, her comrades warned her with death, the person she loved was in danger repeatedly, and now her own life was on the verge of death, and at this moment she finally got her mother's book, and she was almost so excited that she was about to cry.

The pain in her palms was unbearable, suppressing the joy and excitement in her heart. "We have to find a way to alleviate it." She saw a washbasin on the right side of the back of the classroom, and the poison on the padlock was nothing more than getting on the skin, and it should be able to ease down with plenty of water.

"Why was you so careless?" Li Wutong scolded herself secretly, she pinched the pulse of her right wrist hard, trying to stop the poison from flowing rapidly upward, her head was like beads of sweat, she gritted her teeth, and walked towards the sink step by step.

But at this time, Li Wutong didn't know that there was a pair of eyes behind her........
