Chaos...... Bursts of short-wave signals...... Colorful and fantastical endless wormholes...... Quiescence...... Boundless silence......

Suddenly, there was a rumbling and a roar of machinery, mixed with a chaotic human voice...... Splitting headaches.

"Xiaohua! Andy! …… Andy...... Wake up! …… Andy! ”

"How's it going? Are you awake? ”

"Alas...... This hapless kid ......"

"It doesn't seem like a big problem, it shouldn't be too serious. Breathing seems to be normal. ”

"How did this winch be repaired?! It was overhauled yesterday and there was a problem! It's really sloppy......"

Where is this? Zheng Zhi desperately tried to wake up, he felt as if there were a lot of people around him, and he felt that someone was holding his head with his hand, and he was shouting loudly and eagerly: "Hasn't the director called the car yet?!" ”

"The cars were loaded with coal...... The director is in a hurry for them to quickly unload the coal and drive over...... It should be coming soon......" someone around responded.

What's going on? What's wrong with me? How do you feel like so many people are around you? Did I faint? But how did it suddenly become so noisy? The lab has always been quiet, and my colleagues usually speak softly, is this carrying me somewhere? How can there be so many unfamiliar voices and who are they?

The man holding Zheng Zhi hurriedly slapped Zheng Zhi's face: "Andy! Xiaohua! …… Jianhua! Hi! Wake up! ”

His voice was rough, sounding a little unfamiliar, yet familiar.

Andy? Xiaohua? Jianhua? Don't everyone call me Mr. Zheng...... My head doesn't seem to hurt so much...... It's just that my lungs and throat are a little uncomfortable. Zheng Zhi felt panicked, couldn't help coughing lightly a few times and opened his eyes, and found that around him were a group of people wearing miners' helmets and dressed as miners, all with black and gray faces and hands, as if they had just come out of the coal pit, only the circle of eyes was white.

The old-fashioned steel hard hats worn by these people are plugged in front of the miner's lamp, and this large round miner's lamp with black iron shell is inserted on the same black steel hard hat and looks very atmospheric, just like the xenon headlights on a car, which is very cool. Wearing this kind of sleek looking helmet, wearing a black overalls, a towel tied around their necks, a belt tightly tied around their waists to hang self-rescuers and miner's lamp battery boxes, and high-waisted water shoes on their feet, at first glance, they look like typical coal miners from old black-and-white movies of the 20th century.

"Wake up, wake up! Uncle Yongliang, Zhou Jianhua is awake! A young voice shouted, and the white eyes that were staring at Zheng Zhi immediately flickered and became smart.

"You're awake?! Uh~~ Finally woke up......" The middle-aged man who was holding Zheng Zhi and was called Uncle Yongliang finally breathed a sigh of relief, and then asked, "How do you feel?" Are you okay? Can you speak? ”

How do I feel? I feel stupid right now! Zheng Zhi teased himself, isn't this the scene in front of him before the martyrs sacrificed in the old movie? Isn't it time to cooperate with you to say, "Leave me alone!" Go and rescue other comrades first" is such a bold statement that seems powerful? But watching this scene doesn't look like acting, is it really that I have passed out for a long time, so I was made to such a bloody occasion?

Where is this? What happened before?

…… Noisy human and machine voices...... Colorful and mysterious space wormhole...... Shortwave signals, if any...... Dead silence...... In the laboratory, the radar control instrument is constantly jumping with updated yellow, red and green signal parameters......

Right! That's the signal! However, the memory of this signal in my mind suddenly became so distant.

At this time, another memory flooded into his mind: 1983, Zhou Jianhua, the good seed farm, the widowed mother, the younger sister, the younger brother, the school, the winter vacation, the Tuanlin Coal Mine, and the cousin Lin Yongliang who hugged him in front of him......

His eyes widened suddenly, and his mind flashed like lightning: I've crossed over! I've traveled back in time to 1983! I became a junior high school student named Zhou Jianhua!

Just crossed over like that?! Is it because of that distant interstellar signal? I am now Zhou Jianhua, so where did the original Zhou Jianhua go? Will that Zheng Zhi in my previous life become the walking dead? Or is it the end of it?

Zhou Jianhua's mind was a mess, and he was entangled for a while, saying that the world is impermanent, and creation makes people!

"Hi, hi, hi! Are you awake?! Lin Yongliang saw that Zhou Jianhua had been stunned with his eyes open, motionless for a long time and did not answer, he was in a hurry, one hand hugged Zhou Jianhua and shouted loudly, and the other hand shook back and forth in front of Zhou Jianhua's eyes a few times.

"Oh, my head hurts a little......" Zhou Jianhua hurriedly replied, so that the black palm covered with coal dust quickly moved away from his eyes.

"I've seen it, and you've got a bag on your head, and it's not bleeding...... Can you move? Lin Yongliang asked again.

"It should be fine" Zhou Jianhua tried to sit up with his hands propped up, his mind quickly searching for his previous memories, trying to remember how his head hit.

"The mine manager is here!" Someone next to him reminded that everyone turned their heads to look, and some people turned sideways to dodge a pathway.

Zhou Jianhua looked up and saw a burly man in his 40s wearing a half-worn gray tunic, jumping out of the passenger seat of the old liberation truck that had not yet stopped, and was walking towards this side.

With the memories that just emerged in this life, Zhou Jianhua recognized that the person who walked quickly was Chen Guodong, director of the Tuanlin Commune Management Committee and the mine manager of the Tuanlin Coal Mine, who was the leader of this small coal mine of the commune with hundreds of people.

"How's it going?! …… Yes...... Woke up? …… It's good to wake up. Chen Guodong, who rushed over and squeezed into the crowd, immediately relaxed a lot when he saw Zhou Jianhua, who had already sat up on the ground.

Someone rushed into the office and shouted, saying that someone had crashed into a flatbed truck and fainted, Chen Guodong didn't care about asking carefully, so he hurriedly went to find a car and prepared to send him to the hospital.

"Andy, how are you feeling, can you stand up?" Chen Guodong then asked loudly again.

"Okay, Director Chen, I'm fine." Zhou Jianhua reluctantly stood up and replied, took two steps in place, twisted his neck, and felt that there was indeed no big problem, but there was still a faint pain in his head, and he was a little stuffy in his chest, and he always felt like coughing, probably because the coal dust here was too big.

"It's okay if there's nothing to do." Seeing Zhou Jianhua's relaxed appearance, Chen Guodong finally breathed a sigh of relief and said happily, and then he turned his head to Lin Yongliang next to him: "What the hell is going on?!" ”

"Just now, the flatbed truck slipped, Andy hit his head on the car and fainted." Lin Yongliang replied. Lin Yongliang is the squad leader of the second class of coal mining, and Zhou Jianhua is in his class.

"Why did you slip again?! Didn't you just overhaul it yesterday? Chen Guodong asked annoyedly.

"There's no way, it's the fault of the winch, it's been more than a dozen times." Fang Guisheng, the leader of the mechanic squad standing on the side, replied.

"Another problem with the brake control circuit?" Chen Guodong asked.

"Yes." Fang Guisheng replied helplessly.

Zhou Jianhua stood beside him, listening to the Q&A between Chen Guodong and Fang Guisheng, and gradually heard some clues.

In the straight inclined roadways of many coal mines, most of them use winches set up at the wellhead to haul flat trucks to transport personnel and materials. Because the quality of the winch is not up to standard, slipping is a frequent phenomenon, and most of this phenomenon is due to the problem of the brake control system of the winch.

Tuanlin Coal Mine is a township coal mine, and its technical strength is weak, and only fitter Fang Guisheng and electrician Zhuang Minghui are responsible for equipment maintenance.

Fang Guisheng was hired to work in the coal mine after retiring from a state-owned enterprise, and he has good fitter skills, and he is an all-rounder who has a few times to turn, grind, mill, cut, weld and crane, but he does not understand circuit maintenance at all. Zhuang Minghui is a township electrician, and he is blind when it comes to installing electric lights and replacing fuses.

In the past, when encountering problems with equipment control circuits, the Tuanlin Coal Mine could only ask the state-owned Changhong Coal Mine to send technicians to help, but now it is winter, it is the peak season of coal consumption, and each coal mine is the most tense and busiest time for production, so it is not easy to ask Changhong Coal Mine to send someone to help.

"The winch has to be solved immediately. If you don't get it right, you'll die. Chen Guodong said: "Master Fang, you are from the county town, and you work in a factory, and you know more people who know how to do it - no matter who it is, as long as he can help us repair this winch, I will give it to him...... Well...... 30 yuan! ”

Hearing Chen Guodong grit his teeth and say 30 yuan, the surrounding members immediately turned their heads and ears into a commotion. At this time, the average monthly income of the members is only a dozen yuan, and a pound of pork on the market is only 0.7 yuan, and an egg is only 0.04 yuan, how many eggs are worth this 30 yuan!

"30 yuan is a lot, but ...... Where can I find it? Fang Guisheng said at a loss.

In this era, talent is scarce, all kinds of technical personnel trained by the state are uniformly assigned to work in state-owned enterprises, and if the in-service technical personnel of state-owned enterprises privately undertake private work outside their own units to make money, even if they use their spare time, they will also be investigated and punished, and there will even be the risk of imprisonment. Fang Guisheng had read in the newspaper that a technician in a neighboring province was imprisoned for helping other companies do private work in his spare time, and was charged with "speculation in technology."
