Lin Lei glanced at Officer Han and Officer Chen, and said lightly: "You all know very well in your hearts that no one can overcome gravity and levitate in the air without the help of external forces. For example, there is a Western magician named Davis, who has performed various kinds of air levitation many times, and is known as the magician of miracles. One of his most famous levitation techniques is to hover on a double-decker bus with one hand, and the whole person is suspended in the air. ”

Officer Han was a little puzzled and said, "How did he do it? His arms can't be so attractive!"

"Hehe, it's just a simple ruse to say it. Lin Lei said disdainfully, "Later, it was revealed that the hand that Davis paid for the bus was a prosthetic, and his right arm was actually hidden in his clothes, and the whole person was connected to the body through this prosthesis." ”

"There are many such performances using prostheses or other supports, such as some yogis who claim to be able to levitate, but in fact they have a frame in their wide clothing that can be supported. Lin Lei said slowly.

Officer Han nodded as he pondered, "Detective Lin, did Liu Changqing really use a similar method?"

Lin Lei's eyebrows twitched slightly, and he shook his head and said: "Liu Changqing's 'floating on the water' and 'floating in the air' are not the same, and two tricks are used......

Although Officer Han was not at the scene at the time, he had also watched TV programs, so he was no stranger to Liu Changqing's performance.

Officer Han thought for a moment and said, "I once watched Liu Changqing's water rafting show, and after he jumped off the water and got into the water, half of his body was not in the water. He should be wearing a brac-like outfit at this point, right?"

Lin Lei shook his head again and replied, "If you are wearing a support frame on your feet, which is similar to stepping on stilts, then this technique is too low-level, and it is easy to be exposed. ”

"Uh......" Officer Han then asked, "And what method did he use?"

"Those two moving feet are fake. Lin Lei explained, "His real foot sank into the water and stepped on the support frame. And two false feet peeking out of his trouser legs, moving one after the other with his pace. The audience is far away, and from their point of view, Liu Changqing seems to be walking on water. ”

Officer Han suddenly realized, and immediately reacted again: "In this case, there is a support device under the surface of the water? So Liu Changqing is colluding with the theater management of the lake? Otherwise, they are doing these tricks, and the theater management has no reason not to know?"

Lin Lei thought for a moment and replied, "It's possible! But in my guess, Liu Changqing won't let his tricks be known to the management. It is more likely that it is nothing more than to send a large sum of money to the theater manager, and then ...... Everyone understands what he does, and the theater doesn't care. ”

Officer Han and Inspector Chen glanced at each other, and they were silent.

Yes, things that money can solve, generally speaking, are not called problems......

Soon Officer Han diverted the topic and continued to ask Liu Changqing's "Hanging Technique": "Detective Lin, what happened to the Suspended Technique that Liu Changqing performed later?"

After a pause, Officer Han continued: "I once watched a TV show, Liu Changqing sat on a futon, rose from the ground little by little, and finally rose into the air, and someone checked it before the performance, and there was nothing like a steel wire on the scene......

Lin Lei smiled slightly and said slowly: "That's true. Many people who perform the art of hanging in the air actually use extremely thin steel wires to play ghosts. Liu Changqing obviously disdains this, if he also uses steel wire, it will be too low-level. I watched it for a long time, and finally confirmed that Liu Changqing was indeed suspended in the air, without any supporting props. ”

"Detective Lin, this ...... This is not scientific!" Officer Han was a little confused.

Lin Lei smiled and said lightly: "It's very scientific! Liu Changqing understands science very well!"

"Uh-"

Lin Lei's eyes narrowed slightly, and he uncovered the mystery: "Officer Han, you should know the jet engine of the plane, right?"

"Jet engine?" Officer Han slapped his thigh suddenly, "Detective Lin, do you mean that the futon where Liu Changqing is sitting has a mechanism?"

Lin Lei nodded and replied, "That futon is not cheap, it must be very expensive, because it is a small jet engine. The futon spewed out a large amount of gas downward, these gases were colorless, and the audience could not see them at all, with the help of the air flow generated by the jet, Liu Changqing rose slowly...... To put it bluntly, he's just sitting in a small, modified, improvised version of the plane!"

"I see!" Officer Han and Inspector Chen said in unison, both of them showing convincing expressions.

Lin Lei suddenly changed his words, directly locked the biggest possibility of Liu Changqing's fire case, and pointed out the direction of solving the case: "I don't have time to investigate the ins and outs of this fire case for the time being, but at the scene, I smelled a pungent smell, which should be produced after the combustion of flammable gas." If my guess is correct, someone has manipulated Liu Changqing's futon and added some kind of flammable gas to the gas stored in the futon. This gas is extremely unstable, and I am afraid that it will burn when it sees air...... Officer Han, you have to investigate these situations carefully, who understands the relevant knowledge, who has an enmity with Liu Changqing, who has the conditions to move Liu Changqing's futon or who keeps the futon, or who designed the futon...... As long as these circumstances are investigated in detail, it is not difficult to find out who the real culprit is. ”

As soon as Lin Lei's words landed, Officer Han immediately replied loudly: "Yes!"

Inspector Chen nodded again and again, stretched out his thumb and said: "Detective Lin is worthy of being a master of solving cases with the title of detective, Officer Han, Detective Lin is tantamount to teaching you how to solve this case, you must not let Detective Lin down!"

Officer Han smiled and said, "I understand! I will immediately interrogate those disciples and investigate the relevant situation of the futon in detail!"

"Don't go yet!" said Inspector Chen.

Officer Han immediately turned around and left, and then Inspector Chen said to Lin Lei: "Detective Lin is really broad-minded, and many people are reluctant to say their ideas for solving the case......

Lin Lei waved his hand slightly, and said lightly: "It's okay." It's all about catching the murderer, and you don't have to hide it. ”

After a pause, Lin Lei suddenly opened his mouth and asked Inspector Chen, "What the hell is going on with that headless ghost case?"

Police Inspector Chen took out a stack of materials from the briefcase he was carrying and handed them to Lin Lei: "Detective Lin, take a look......

Lin Lei took the material and looked at it carefully......
