Xiao Zhang, with a layer of cold sweat, hurried back to the campus.

The 741 robot that had saved his life followed behind, running crunching, if it weren't for the fact that it was just a low-level robot with less than 1 life intelligence, it would definitely scold its owner for having no conscience.

Xiao Zhang's concern now is not his life, but the cleaning robots at school.

As soon as Fang stepped into the campus, he couldn't wait to take out the computer, and with just one glance, his face turned white.

The cleaning system showed that the cleaning robot that was still alive, plus the one at his feet, made a total of 724, and the other 300 were all out of touch, needless to say, all fell in the grass. If yesterday 40 was bearable, then today 300 will let him go berserk, and someone is going to put him to death.

He didn't have time to think about who was fixing him, carrying his schoolbag, running around the campus like a mad dog, from the dark corners, among the flowers and plants, and behind the big trees, twisting out the cleaning robots with their heads drooping.

Just like last night, these robots all smelled of burning, and when they opened the maintenance window behind them, they could see that there were scorched marks on the control board of the energy cabin, needless to say, it was the damn high-frequency electromagnetic wave that penetrated the microcircuit group.

Repairs are imperative.

But he didn't want to go to Luo Li again, so he called her over at half past ten yesterday, and scolded him with a slap in the face, and 40 robots offered 10,000 yuan. It's eleven o'clock today, 300 robots, even if he can endure the scolding of little Lori, he can't stand her lion opening his mouth. If he really invited this little aunt and grandmother to come over, he was sure that he would not be able to satisfy her appetite after sweating and bleeding for a month.

Fortunately, he looked at the general process of Lori's little beauty welding yesterday, although it was vague, but after careful pondering and trial and error, he will definitely find the maintenance know-how. There is also welding equipment, and his neighbor Huo Laotou's small yard in the garbage heap, just throw a small gray box at random, he paid special attention to it last night, it is fully equipped, and it will definitely work.

Ten minutes later, 300 damaged robots were carried by the cleaning robot into the basement of the hangar, and all of them were piled up in the A02 courtyard.

Old man Huo had already slept, and from the half-open door of A01 came the sound of snoring like a pig, and the chaotic footsteps could not wake him up from his sweet dream.

Xiao Zhang took the welding box from the courtyard of Old Man Huo's house, put on a good posture, put on blue light welding sunglasses like a little beauty in Lori, and pondered the essentials of the little beauty in Lori, and finally buried his head in the damaged microcircuit group.

In the blue sunglasses, a small and complex world is revealed, with thousands of electronic circuits with a diameter of 10 nanometers distributed like spider webs in an area the size of a thumb. There are several holes in the middle of these nano-electronic circuit networks, and only by filling these burnt holes completely, it should be done.

However, things are not so simple, because many of those burnt lines are curled together, it is difficult to tell who corresponds to whom, and it is difficult to accurately solder them.

He took the micro nano welding torch and welded it meticulously.

Fifteen minutes later, the first robot was finished, he wiped a handful of sweat from his head, breathed a long sigh of relief, turned on the computer, and tried to activate it.

Unfortunately, there was no reaction in the computer, and the first welding failed.

"Come again!" Xiao Zhang gritted his teeth and buried his head on the maintenance port......

After another five minutes, he raised his head again and tried again, still failing.

"Come again! I don't believe that little Lori can do it in ten seconds, I can't do it in an hour. Xiao Zhang muttered to himself.

……

An hour passed in the blink of an eye, and what made Xiao Zhang's classmate vomit blood was that he tried twenty times in a row, and the first damaged cleaning robot was still stubbornly lying on the ground.

His limbs were numb, his eyes were full of stars, and he had the urge to stomp on the damn cleaning robot on the ground.

"Scumbag, you don't sleep so late, what are the cats doing here?" There was a lazy question behind him, and Old Man Huo yawned, wiping his eyes and looking at Xiao Zhang weakly.

Xiao Zhang glanced back at the little old man, and said angrily: "Didn't you see that I was repairing the robot?" ”

"Yo, you can also fix robots? Is it fixed? The little old man asked, scratching his hair like a chicken coop.

"Nope! This is delicate work, how can it be so easy to repair, okay Huo Gong, go to sleep with your big sleep, don't hinder my work. Xiao Zhang waved his hand and continued to bury his head.

The little old man didn't leave, but took a step forward, put his hands behind his back, lowered his head, and looked at the maintenance port with a pair of confused old eyes.

Three minutes later, the little old man's face showed obvious disdain, and he raised his hand and gave Xiao Zhang a slap: "Dead boy, just if you weld like this, you can't repair it in 10,000 years!" ”

"Huh?" Xiao Zhang turned his head, took off his blue light welding sunglasses, and looked at the old man strangely, "Huo Gong, listen to your tone, do you know how to weld?" ”

"No!" The little old man rolled his eyes and snorted.

"Then what are you hitting me for?" Xiao Zhang was angry and funny.

"Cut! My old man stopped playing with this toy forty years ago, which is the most basic job, and the average junior high school student would. You're such a scumbag, I don't want to pay attention to you, sleep! The little old man shook his head again and again, turned around and walked out of the courtyard gate.

Xiao Zhang hurriedly got up and grabbed the old man's arm: "Huo Gong, I know you will, teach me, right?" You see there are 300 damaged robots piled up here, if I can't go to work before 5 o'clock tomorrow morning, I will be kicked out of Harvard by Director Qiao, you finally have a neighbor, you won't be ruthless to let me leave, right? ”

The little old man scratched his head and glanced up and down at Xiao Zhang: "What benefits can I get?" ”

"This ...... You make an offer! Xiao Zhang caught the old man's thief light and nodded solemnly.

The little old man laughed: "How much did that little Lori take from you last night?" ”

"Ahem! Thousand! Xiao Zhang blinked.

The little old man pondered for a few seconds, seemed to believe Xiao Zhang's words, stretched out his hand and nodded: "Okay, 25,300 for each one, then 7500, pay in cash or transfer?" ”

Xiao Zhang smiled dryly: "Huo Gong, I am a student, there is money there, in two days, when my mother comes, I will pay you immediately." ”

"Really? Why did you have money when you kid secretly stuffed money into Lori's chest in the grass yesterday? It seems that you are very dishonest, let the little Lori come and serve you, the old man is asleep! The little old man took Xiao Zhang's hand away and pretended to take a step.

"Wait! Huo Gong, how do you want to cultivate? Xiao Zhang understood that this was the little old man's deliberate manipulation, and estimated how much he paid to the little Lori, and the little old man was clear.

The little old man turned around and stretched out a dry finger: "10,000 on credit, 5,000 in cash." The little old man doesn't have a black belly like a little Lori, so he won't kill you casually. If you can, just sign and draw, and I will arrange the maintenance immediately, and ensure that it will all be done for you in an hour. Comes with a tutorial on how to solder a microcircuit bank. ”

After the little old man finished speaking, he took out a card-type electronic contract from behind his buttocks, and handed it to Xiao Zhang with a smile.
