No one answered. Xu Qianqian held her breath, as if her little voice would be heard by the air beside her.

If what was just now like a reasoning game or a thinking exercise, now it's starting to enter the cold reality.

Apparently their own people, replacing bearings, placing magnets, pointing directly at the in-house engineers. The threshold is already very low, not only Liu Ruiyang can do it, almost any relevant engineer in the factory can.

That's still a lot of range.

"He's in India."

"Why?" Liu Ruiyang's voice was a little dry. The four engineers who came to India were naturally the most outstanding, and Liu Ruiyang's decision to bring them here also meant to experience and cultivate.

"You didn't see a magnet just now, did you?" Huang Ligong said coldly.

Liu Ruiyang naturally didn't see it. The saboteur had to be in India in order to get the magnet back in time afterwards and erase the traces. "Maybe you didn't use a magnet." Liu Ruiyang said weakly.

"Changing bearings, and all sorts of small actions, is always appropriate in India, right?"

Liu Ruiyang didn't speak. No matter how unwilling he is, he can only accept it, the saboteurs are among the four people, three engineers on the scene, Li Jia, Chen He, Guo Weiqiang, and one maintenance engineer, Wang Shun. Four elites.

"He's got to get him out tonight." Huang Ligong turned around, he had already made a decision in his mind. "We're in two ways. The first way is to go directly to them and talk to them one-on-one. After a few minutes of talking, you might be able to see it. ”

Liu Ruiyang and Xu Qianqian both nodded. Most of the time, positive communication is the most effective way. Liu Ruiyang knew his right-hand men, and he didn't believe that they would be so-called professionally trained spies.

He also subconsciously felt that direct communication was also a chance for them to defend themselves.

Huang Ligong looked at Liu Ruiyang. Liu Ruiyang met his eyes and waited for him to speak. Huang Ligong didn't speak, still looking at him with a smile. Liu Ruiyang's face gradually became a little stiff and shook his head.

"Shouldn't it be you?"

Huang Ligong looked at him stubbornly and said, "Of course you are the most suitable." I know yourself better than you do. ”

He has good reason. Liu Ruiyang is the spiritual symbol of Kunpeng engineers, very popular, the engineers in the factory like him, like to ask him for advice on work, and are willing to talk to him about things outside work, unlike seeing Huang Ligong, respectful and respectful, polite with distance. Liu Ruiyang also soaked in the engineer pile every day, and he ate and lived together, and he was very familiar with them. In this situation, it is obvious that Liu Ruiyang is more suitable to talk to them, and he can be more aware of their subtle discomfort and abnormality.

"If you want me to trick them, I'm afraid I'm more nervous than them." Liu Ruiyang is now a little nervous, more precisely, annoyed. Huang Ligong smiled mysteriously and took out his mobile phone, he had a better plan.

Wooden horse.

The Trojan program that has been disguised, Liu Ruiyang only needs to find a reason, technical documents, internal documents, photos, or whatever, as long as it sounds credible, and forwards it to a few engineers. When they click on it, the Trojan program is automatically downloaded, secretly installed in the mobile phone, and listens to calls, text messages, and even the input of the system's built-in keyboard, which is automatically sent to the designated mailbox.

Liu Ruiyang frowned, clasped his hands to his chest, looked at the ground, and did not speak.

Huang Ligong's mobile phone has reached the last step, as long as he presses "send", the Trojan will be transmitted to Liu Ruiyang's mobile phone. "Ruiyang, this is not a trivial matter." His hand hangs over the screen of his phone. "It's not a trivial matter for Rui Li, a mole, a small move, will ruin your hard work for more than a year. Can we afford it again?! For that person, it's not a trivial matter either. The evidence must be conclusive, we can't chase the wind and catch the shadows, we can't rely on subjective determination, no matter who it is, no matter how sure we are in our hearts, if there is no evidence, do we dare to make a move? What if you wronged the good guys and let the real bad guys go? We must have hard evidence. ”

He paused for a moment, seeing that Liu Ruiyang had not reacted, coughed dryly, and said a little sadly, "Now I use unconventional means, just to avoid worse results." If there is no conclusive evidence and we can't find out the mole, what should we do? Worst of all, you want me to fire all four of them......"

Liu Ruiyang raised his head, "After finding that person, can the Trojan be deleted?" ”

"Yes. Just let it fail, it's a dead file, and I won't be able to activate it in the future. ”

"What the Trojan horse sends back can only be seen by you and me. Except for the direct evidence, everything else has to be deleted. ”

"Deal!"

Huang Ligong pressed the "Send" button.

After being silent for a while, Liu Ruiyang had no intention of moving, and asked, "What about you?" What is the second way? "Gotta find a topic to continue the silence. What Huang Ligong just said is like a life-saving straw, and tonight must solve the problem, and the troops must be divided into two ways.

Huang Ligong actually hadn't thought it through, and said in a deep voice, "The suspects have all been found, and if you go to interrogate, I don't seem to have anything to do." Unless it's ...... "Tonight is like doing a scientific experiment, come up with ideas, narrow down the scope, compress the huge possibilities to the smallest scale, and then screen them one by one." Just now, they've narrowed the range to a very small scale, four people, two parts. He spun in circles, it was his habit of thinking. "Those two parts ......"

Liu Ruiyang said in a dull voice, "You said that the bearings and magnets should have been thrown away." ”

Huang Ligong smiled bitterly, "Yes, it's useless to raid the room." After a pause, he added, "It must not be far." ”

"It's useless to dig three feet into the ground here, and even if you find it, you don't know who threw it."

Huang Ligong scratched his head.

Liu Ruiyang pointed to the robot, if someone is really sabotage, then the bearing of the culprit is there.

"Hey, can you find anything out of this bearing?" Xu Qianqian suddenly saw a glimmer of hope and asked. "If you have done warehousing registration, there will be a record of delivery, and you can find out who took out the used bearings."

Liu Ruiyang and Huang Ligong shook their heads at her. Kunpeng is a start-up, and the cleaning robot is a project under development, everything is based on speed and efficiency, and there is no standardized inventory management for defective products, so that an engineer can get the discarded parts at hand.

She didn't give up and asked, "Can you check, how did he bring it?" ”

Huang Ligong's eyes lit up and looked at Liu Ruiyang. The saboteurs must be prepared in advance. It is still possible to get the magnet in India, but the bearing must be stolen from the factory and brought to India. Moreover, these two parts were installed on the robot after arriving in India, and if they were installed in advance in China, it would be too easy to be exposed. There will always be another debugging once or two times before bidding, and the robot will fail in advance. "So, these two parts, at least the bearings, are on him all the way."

"Hmm...... The idea is yes, but a node is needed. You have to leave a clear record so you can track it down, right? ”

Huang Ligong seems to have been poured cold water. Indeed, he can't travel through time and space, and even if he can, he has to travel four times to track down four engineers. There must be a node that retains traces of the time, or is kept as a clear record. He struggled to map out the man's whereabouts in his head. He sneaked into the small storeroom, took out the bearing, and put it in his bag. He didn't dare hide in his workstation, he had to take it home. Pack your bags and hide them in your suitcase. On the morning of departure, assembled at the unit, a pickup truck and a sedan pulled everyone to the airport. Queued up separately to go through the security check, and when I arrived in India, I queued up separately to enter the customs. Then a bus pulled everyone to the photovoltaic base and checked into the rooms separately......

Even if records are kept in these places, they are also personnel information, and even the suitcase is not registered, let alone a small part inside.

"Warehouse...... Pickup...... Aerodrome...... This side of the airport...... Bus...... Accommodation room ...... The bus ......" Huang Ligong muttered, counting back and forth. Suddenly, he knocked heavily on the table, his face flashing with excitement, "There is." ”

"What?"

"Airport."

Aerodrome?

"It's a long story. I'll leave quickly, and I'll report back to you when I get back. ”

Huang Ligong picked up his coat and put it on, touched the car keys inside, and turned around to go out. Liu Ruiyang was hovering in his heart with awkwardness and questions, and rushed out, "Hey, you have already thought about implanting a Trojan horse in their mobile phones, so you say that I am the most suitable, right?" ”

Huang Ligong laughed, saw Liu Ruiyang's face, put away his smile, and said loudly and undoubtedly, "Ruiyang, you should know me!" He waved his hand vigorously, said goodbye to Liu Ruiyang, didn't give him a chance to speak, and walked out quickly. walked past Xu Qianqian and said casually, "You come with me and do activities." ”

Xu Qianqian followed behind Huang Ligong. A few more steps, she stepped out of the light of the house and into the cold night. Looking at Huang Ligong's blurred back, Xu Qianqian suddenly had a strange feeling, as long as she followed him out of this door, the self she worked hard to find tonight, the self who was full of laughter and anger, would sneak back. No, maybe she had already sneaked back earlier, when she got more praise from Huang Ligong and voted for him, trying to give advice for him, not for the thing itself, when Huang Ligong casually called her just now, she didn't ask anything, just obediently followed.

"Miss Xu......" Liu Ruiyang's voice came from behind him. Well? Xu Qianqian stopped and turned her head. Liu Ruiyang wanted to speak again and again, and finally said, "The story I just told about the Soviet spy who used a magnet to get U2 is just a wild historical legend, don't take it seriously." ”

Liu Ruiyang didn't know why he wanted to say this to her. Xu Qianqian looked at his face with distinct features, completely under the light, with nowhere to hide, and there was an indescribable meaning in her heart. She nodded.

"Boring." Liu Ruiyang smiled bitterly and was a little tired, "No matter how boring history is, you can make up interesting stories, right?" ”

Xu Qianqian walked up to him and hugged him gently.

The storeroom was deserted again. Liu Ruiyang looked into the air, the headlights above his head shone down, the dust in the air rippled slightly, the more the light faded to the edge, and the walls on all sides—walls that protect and restrain people—retreated vaguely behind the shadows. Lighting comes at a cost, dams are built, coal is burned, nuclear materials are burned, sunlight is captured, high-voltage power grids are built, and they are transmitted to every corner before they fail, and finally you have to pay the electricity bill to let the light shine into the darkness with a single touch.

Liu Ruiyang felt tired for a while, and forgot to sit down just now. He sat down in his chair, bent over, and looked at the shadows on the ground. After a long while, I exhaled deeply, clutched my phone, and walked out of the warehouse.
