"I just remembered a story." Liu Ruiyang seemed to have figured out all the key details, he clasped his hands in front of his chest, but the expression on his face didn't look very excited, with the tiredness of the long-pending problem suddenly solved.

In the 1950s, during the Cold War, the United States developed the U2 reconnaissance aircraft, the famous "Black Widow". This is a masterpiece that makes other countries desperate, U2 can fly at an altitude of more than 20,000 meters, fly over the airspace of other countries wantonly, reconnoitre, snoop, photograph classified military facilities, although the Soviet radar quickly discovered, but U2 really flew too high, not to reach it, let alone intercept. However, in 1960, the Soviet Union miraculously shot down a U2 plane and also managed to capture the pilot alive.

The United States is puzzled. The Soviet MiG's aircraft and anti-aircraft missiles cover far from enough altitude, which is more than 10,000 meters, how can it be possible to shoot down a U2 of more than 20,000 meters? It seems that there is only one possibility, the flight altitude of the U2 at that time was not enough, and it was more than 10,000 meters, so it was knocked down. There is no problem with the plane, and it will not be so outrageous if it goes wrong; There is no problem with the pilot, otherwise it would be good for him to land directly in the USSR with the plane, and shoot it down. The United States thought of the most realistic scenario, which was spies.

The doubts lie here, and it is not difficult to understand that it is a Soviet spy who infiltrated, touched or even blew up a U2 plane. But to say that hijacking and tampering with the flight system is a fantasy. U2 was a top-secret project, and it was impossible for the Soviet Union to obtain its technical information, let alone "jailbreak". If you can get the technical information and have such a thorough understanding, the Soviet Union will build the U2 by itself, and there is no need to shoot it down and take the wreckage to reverse it.

When they arrived here, Huang Ligong heard it, and it was indeed quite similar to their current situation. He thought for a moment, shook his head, and couldn't figure it out.

"The Americans don't understand it either." Liu Ruiyang comforted him. In order to solve this mystery, the United States did not hesitate to secretly make a deal with the Soviet Union, exchanging the captured high-ranking spies of the other party for its own pilots. However, the hapless pilot recalled all the details and couldn't figure out what the situation was. The mystery was gradually revealed later.

The truth is simple. It was indeed a Soviet spy who did it, a spy who did not know how to fly at all, in a very simple way.

A small magnet.

"You wait!" Huang Ligong didn't let Liu Ruiyang continue, and his mind quickly worked, "...... Barometer...... No, no, it's too strenuous...... Dial...... Dial ......"

He slapped his thigh hard, "Altimeter pointers!" ”

Liu Ruiyang smiled, "Guess fast enough." ”

It's that simple way. The real challenge of the spy is to get close to the plane, the idea to get into the cabin, and one minute is enough. As soon as he entered the cabin, he pulled out a small magnet from his boot, found a suitable place under the altimeter dial, placed the magnet, and slipped out as if nothing had happened. U2 took off, flew normally, entered the airspace of the USSR, raised the altitude, the altimeter needle gradually turned, eight thousand, nine thousand, ten thousand...... Getting closer and closer to the small magnet, the magnetic force became stronger and stronger, dragging the pointer to a higher scalar number, and finally pointing to 20,000, in fact, the real height was more than 10,000. This height was enough for three MiGs to follow it unconsciously, biting tightly, interfering and flanking, and the panicked U2 aircraft struggled to protrude from the encirclement, while another MiG rushed out diagonally and crashed into its long wings.

A spy, a gadget for less than $1, two minutes, get a plane worth tens of millions of dollars.

"Miss Xu's words inspired me. Lao Huang, we all fell into a preconceived misunderstanding, and we subconsciously believed that if the accident was man-made, those interlocking links must have been carefully designed. ”

Huang Ligong suddenly brightened. Yes, it is really impossible to say that someone controlled the accident precisely. But why is it necessary to be accurate? Perhaps, the troublemakers themselves did not expect such a perfect result? Is it possible that he just wanted to step on it and cause some damage, but it turned out to be an avalanche, a perfect storm?!

From this perspective, there are some factors that can be ruled out. The fine grains of sand in the Indian desert, the sealing level, the electromagnetic interference of the Indian photovoltaic power plant, and the worst of all, the cumulative error, are all beyond the knowledge of the designers. If Liu Ruiyang and the team are not aware of it, and have not done in-depth research, it will be difficult to become the design basis of the disruptor.

There are few factors left.

"Bearings." Liu Ruiyang raised a finger. The bearing, which was a little worn, did not seem to be entirely attributable to the quality of the product and the Indian sand.

"Magnets." Liu Ruiyang raised his second finger.

"I'm afraid ordinary magnets won't work."

"Electromagnetic fields are superimposed. Or, what if it's a neodymium magnet or something? The right location, close to the control system, can interfere with accuracy and can cause time lag. ”

Huang Ligong nodded vigorously. "There's no third one, is there?"

Liu Ruiyang moved his third finger and thought for a while, "Not at the moment." ”

Once the key threads are reached, hidden patterns can easily emerge. The saboteur may have only done two small things, one is to replace the bearing, replace the worn bearing that is not good enough, and interfere with the precision measurement and precision behavior; The second is to put a strong magnet such as a neodymium magnet in a suitable position to interfere with the sensor and reduce the position accuracy. From this point of view, his real intention is only to influence the performance of the Kunpeng robot and make it perform poorly in the examination room.

Not vicious, but stealthy enough. The robot that made its first public appearance did not perform as well as it should, and it was commonplace that it would not be easily associated with sabotage. It's just that I didn't expect that a series of unexpected factors caused things to get out of control. The fine grains of sand in the Indian desert exacerbate the damage effect of wear bearings, and the electromagnetic interference of Indian photovoltaic power stations superimposed on the magnetic interference of strong magnets not only disrupts the control system, reduces its calculation accuracy, but also causes cumulative errors, and finally becomes a dramatic accident.

Huang Ligong paced quickly in the room. Liu Ruiyang solved the problems in front of him, and then his field was in the back. Xu Qianqian saw the Huang Ligong she was familiar with again, the Huang Ligong who was full of energy and sent a war letter to the other party with a provocative smile on his face, and the Huang Ligong who was decisive and fierce.

"That's the last key question left."

"Huh?"

"Who did it?" Huang Ligong stopped, facing the dim red robot, his tone with a fierce aura.
