"Wei Wenlong. I settled down, said a word in a calm voice, and slowly approached the figure in front of me. Yu Wenlong looked at me and didn't say a word, just slowly stuffed the mobile phone in his hand back into his cloak.

"What a situation. I walked up to Yu Wenlong and looked at him face to face.

Wei Wenlong's face was calmer than I expected, or rather, a little colder:

"Gao Qinghua, violated Xiao Tian. As he spoke, Wei Wenlong's grim face showed a strange smile, and that smile didn't know whether to say it was cold, self-deprecating, or sad and angry.

"Gao Qinghua violated ...... "I don't quite understand what Wei Wenlong means, but I already know that I'm afraid things will develop beyond my expectations. "But it's sweet...... Isn't that your sister who was taken from the orphanage?"

"Mengxin is Xiao Tian. ”

Yu Wenlong said bluntly.

My brain buzzed, and it took me two breaths to calm down.

"You...... I see. I understand. I didn't expect her to lie to you for so long. ”

"That's right, I've been lied to all the time. I've been deceived by that girl. All my life, I have always believed that I was smart, and today I realized that I had been toyed with by my sister. DO YOU THINK I'M THE STUPIDEST PIG IN THE WORLD?"

Yu Wenlong smiled sadly, although he was laughing, but his voice was sad and sad, and I saw a thin line of cold tears, slowly sliding down from the corners of this rational man's eyes.

Wei Wenlong hung his head, turned his face away, and then he took a crumpled piece of paper from the inner pocket of his slightly crumpled cloak and handed it to me.

It was a pink piece of stationery.

I hesitated, but finally took the paper he handed me.

I unfolded the pink letterhead, and on it was written a paragraph that looked like a little girl.

It reads as follows:

"Brother Wenlong. Dad has found a carpenter job in Shanghai, and we're moving out tonight. Brother, I'm sorry I lied to you for so long in the past two years. Actually, I couldn't help but want to tell you that I was Britney several times...... But I don't want you to know that the boss who adopted me gave me away because of debt, so I kept pretending not to know you and hiding it from you...... Brother Wenlong, thank you for being my tutor for teaching me to learn for the past two years. Although I don't understand a lot of the things you taught me so smartly, I still like the feeling of being with you. However, I can't delay your future, and the school won't let you open the restaurant, so my dad and I have to leave. Brother, I heard that you stabbed someone in school recently, I was really worried when I heard this, I was so scared, I know you are not that kind of person, I am really worried about you, I don't know if you will go to jail or be kicked out of school. But I have to go, and I'll be glad if you're okay and can go back to school. Brother, you have to make sure you're in good health. In the future, you must no longer be partial to eating, because no one will give you red dates anymore. ”

The following bylines are:

"Britney. ”

This was the end of the letter, and when I saw the final signature, I felt a wave of sadness in my heart, and I couldn't help but sigh.

Everything fell into place.

Xiao Tian is Meng Xin, and Meng Xin is Xiao Tian.

Xiao Tian, who was supposed to be adopted by a nouveau riche, fell into the hands of the owner of the small restaurant because of the nouveau riche's middle way, and became his daughter.

It's just that Wei Wenlong never knew about it.

The smart Xiao Tian has been hiding this from Yu Wenlong.

Hiding this brother from himself, just to ...... Don't let her brother think that she is having a bad time and worry about her.

That's all.

Suddenly I heard a sobbing sound, I slowly turned my head, only to see Yu Wenlong pinching his face with both hands, as if he wanted to pinch back the tears flowing down his face.

I didn't bother Wei Wenlong, just quietly watched his reaction, I knew that at this time, he needed catharsis and a calming process.

A night breeze blew and tickled the ends of my hair.

Long.

The tremor of Yu Wenlong's hand pinching his face slowed down slightly, and Yu Wenlong's voice that forcibly kept calm came out slowly:

“...... This letter was found under the roll door of the old restaurant at the school gate...... Later, I sneaked into Gao Qinghua's office and found this ......" As he spoke, Wei Wenlong threw me a ring-shaped thing.

I caught it, frowned, and realized that it was a red hair ring.

I suddenly remembered that Mengxin's long braid did have this hair ring.

"This is what I gave to Xiao Tian. It has the word 'Yolanda' written in Spanish. Yu Wenlong said to me in a somewhat choked voice.

I flipped the inner ring of the hair tie to the outside, and sure enough, I saw a line of "Yolanda" on it.

"Violet ......" I know that Yolanda is violet in Spanish, and the flower language of violet is ...... Pure love.

"I also found four of Sweetie's hairs...... Her hair smelled of red dates, and I knew it when I smelled it...... What Gao Qinghua did that brute did, everyone knows it......"

Yu Wenlong said bitterly, "At that time, I had already guessed what was going on. So I followed Gao Qinghua to the police station to record a confession, and finally tracked him to his house, where he lurked downstairs...... In the end, I took the opportunity of him going out to see his son Gao Xueqin at night and found him and forced him to tell the truth...... The truth, too, is the same as I guessed...... He took away Xiao Tian's red pill. ”

I took a slight breath of cold air.

The heartbeat was slightly twitching.

At this point, I don't really know what to say.

From Yu Wenlong's understatement, I can guess that Mengxin ...... Or Xiao Tian, for her brother, how much did she pay behind the scenes. I've had a similar position, and of course I feel the same way.

At that moment, just a sentence flashed in my mind over and over again:

No matter how smart a man is, he can't be as smart as a woman after all.

"What do you have in mind now?, do you want to run away?" I asked, looking at Yu Wenlong.

"No, you don't. Yu Wenlong shook his head, "I didn't reveal my identity, and no one found me." Originally, I wanted to kill Gao Qinghua a few days later, but today Gao Xueqin was hospitalized, and Gao Qinghua's wife was also accompanied by the hospital, Gao Qinghua was alone at home, and because of the investigation, he didn't get home until midnight, so I found a chance to start. ”

Didn't show the horse's feet...... Hearing Yu Wenlong say this, I was relieved. It seems that the situation I feared most did not happen.

"How did you kill him?" I wondered. Seeing Wei Wenlong's relatively thin body, I was a little puzzled by his method of killing.

"Plastic bombs. Yu Wenlong said an astonishing sentence, "I did it myself." ”

"C4......? Where did the material come from?" I was a little shocked by Yu Wenlong's words.

"TNT was obtained four years ago at the blasting site of an adobe house contracting project. White phosphorus was obtained by infiltrating the laboratory when I was in junior high school. The likelihood of a police finding out is almost negligible. Wei Wenlong said, "I know the basic process of the police laboratory team, generally the police use ethanol, acetone, carbon tetrachloride and other organic solutions, and then cover the filter paper on the explosion fragments for extraction, and finally separate gunpowder particles, metal powders, and combustion products." Separation tests and smoke reaction experiments can best figure out the chemical composition of my plastic bombs, but it is almost impossible to figure out the source of TNT and white phosphorus based on the residues. ”

When he said this, Wei Wenlong was surprisingly calm and confident.

"I put a double layer of highly absorbent oiled paper on the surface of the gunpowder inside the plastic bomb, with magnesium and sodium metal sheets in the middle of the double-layer oiled paper, and then the outer layer is coated with distilled water, and the outer layer is alcohol. As long as the gunpowder explodes, the metal magnesium that ignites when it meets the fire will burn the internal structure of the plastic bomb and some evidence at the scene, and the molecular structure of many components will be disrupted, and it is even more difficult for the police to test it. ”

"Didn't leave any other clues?" Although Wei Wenlong expressed full confidence in his actions, I, who had not witnessed it, could not be 100% assured.

"If there was a one percent chance of falling short, I wouldn't have taken this step. Wei Wenlong replied calmly, "Don't worry." At best, the police will suspect me, but there will be no evidence. ”

"Yes, in that case......" I looked at Wei Wenlong calmly for a full two seconds, and then grinned, "I have to praise you for a good job." ”

After that, I laughed, stretched out my hand and patted Wei Wenlong's thin shoulder.
