"Yes. That guy has always seen me as a thorn in his side. He said one day, he would put me in prison!"

"Now, Lu Pei won't dare to arrest you."

"Okay, let's go!"

Li Yunshan was waiting below, not knowing what Lang Xiaobai was doing on the ceiling, only hearing the sound of "gurgling". After a while, he came out of the passage in the wall of the living room.

"The car is waiting outside, let's go!"

Afterwards, the two got into the car and drove down the street late at night. After a while, the car stopped outside Fu Yucheng's house.

"Oh! It's not as serious as I thought. ”

A large hole was blown in the wall, and the glass of the window was shattered. However, the other houses were not much damaged

The crowd waiting outside to watch the excitement crowded into the house to see the scene of the explosion. can

Yes, the security guards are very watchful, and none of them can get in.

After Lang Xiaobai and Li Yunshan arrived at the house, they immediately ran into the study to check, and then returned to the living room. At this moment, the detective and Lu Pei also walked out of the next room.

"Mr. Lang Xiaobai, thank you so much! Thanks to you, we were able to save our lives, and on behalf of all of us, I would like to express my sincere gratitude to you. ”

The detective held Lang Xiaobai's hand tightly, revealing sincere feelings.

However, Lu Pei, who was standing on the side, looked very unhappy and glared at Lang Xiaobai fiercely. "This guy must think that I planted the bomb in advance......"

Lang Xiaobai looked at Lu Pei and secretly laughed in his heart.

"Mr. Lang Xiaobai, I really want to know where the bomb was buried? Who is the murderer?"

"I don't know. However, I am sure that it will not be long before it will be clear. A fifth letter is coming out tonight, and I think that after reading that letter, I will probably get an important clue. The fifth letter should be on the verge of appearing. ”

Lang Xiaobai asked Li Yunshan to turn off all the lights, light candles, and asked all those present to be quiet.

Everyone gathered quietly around the lamp. The candlelight illuminates everyone's face. Lang Xiaobai suddenly raised his head to look at the luxurious and brilliant multicolored lanterns hanging from the ceiling.

"Ten seconds to go...... Five-second ...... Three seconds ......"

Lang Xiaobai counted in a whisper, and everyone looked at his expression. "Look! It's out!" Suddenly, Lang Xiaobai screamed. Everyone couldn't help but look at the ceiling he was pointing to.

A white thing, like a dead leaf blown off by the autumn wind, slowly floated down. Lang Xiaobai reached out and caught it in the air.

"This is it!"

It turned out to be a letter! It's the fifth letter. Lang Xiaobai took the letter and gave it to the detective.

The detective read the letter and found nothing important, and what it said was just a repetition of the past letters, and everyone was very disappointed.

"Where did the letter come from?" The detective looked at the ceiling and asked Lang Xiaobai. "From there!"

Lang Xiaobai pointed to the colorful lanterns and said:

"Li Yunshan, please take off the lamp."

Li Yunshan climbed into a chair, unloaded the lamp, and placed it on the table, and there was a metal box on the multicolored lantern.

Lang Xiaobai opened the box and saw that it was filled with gears, clockwork and other clockwork-like parts, and there was a slender hole under the box.

"Detective, do you see that? The letter was placed in this box, and because of the rotation of the mechanism, it fell out of the hole at a certain date and at a certain time. ”

So, the letter was put in from the beginning

"Of course! It's all made of clock parts, and the explosion is caused by a time bomb that has been planted in advance!"

"Who did this?"

"Of course, it was set up by the murderous devil. He plans to deliver the letters to us in order, and then blow up the living room and destroy the secret mechanism on the multicolored lanterns so as not to leave physical evidence. However, what was not expected was that the explosion was not powerful and did not blow up the box. This can be said to be that people are not as good as heaven!" Lang Xiaobai said.

"But when did they install it? Since the murder of Fu Yucheng's father and son, the security personnel have been guarding here all day and night, and they can hide from so many people and arrange this secret organ, which is indeed not something that ordinary people can do. ”

"Nope! Detective, this is a secret mechanism, which was arranged before the murder of Fu Yucheng's father and son happened. ”

"On what basis do you think so?" Inspector Wu asked.

"Before the demon was poisoned, he installed this mechanism, the purpose was to make everyone think that Xiao Xiurong and Luo Cai were in love, and murdered Fu Yucheng's father and son. Please recall what was written in the second and third letters, Fu Yucheng was afraid of being murdered by Rhodes. ”

"Yes."

In other words, the murderer tried to blame Xiao Xiurong and Luo Cai. When it first happened, even I was deceived. Only later it turned out that they were not only innocent, but also poor victims. ”

Lang Xiaobai continued: "The murderer used a lot of means in order to make Xiao Xiurong unable to get rid of the charge. For example, on the night of Fu Yucheng's murder, Xiao Xiurong would return home within an hour and a half after watching the opera, and there was no way to provide proof of alibi, and Xiao Xiurong's canine teeth marks were also a means used by the murderer. ”

"However, these letters were written by Fu Yucheng himself." Inspector Wu was a little puzzled.

"That's right, he wrote it himself." Lang Xiaobai said.

"Then, your inference is that Fu Yucheng hates his wife and loves Rode. So she wrote these letters, and set up this ingenious machine in an attempt to guillotine her wife and Rhodes. Inspector Wu said.

"Yes, Fu Yucheng is an electromechanical technician, and there is nothing impossible to install such a machine."

"However, when you think about it, it does seem a little unreasonable. Fu Yucheng went to the Security Bureau and kept saying that he was about to be killed, and that he didn't want to die. At that time, his expression was not pretended, no matter how you looked at it. Therefore, I do not believe that this machine is his device. ”

"If you don't believe me, I can give you a more detailed explanation."

Lang Xiaobai looked at the expressions of everyone present, and then said a set of shocking strange news.
