signed a contract to borrow 10,000 yuan, and Xiao Zhang felt that the burden on his body was getting heavier and heavier.

Old man Huo was not worried that Xiao Zhang would not be able to pay the bill, and after putting away the electronic contract, he took out a thumb-sized mini remote control from behind his buttocks and pressed the first button on it. A few seconds later, two small wood-colored round stools slid out of room A01.

The small round stool is two feet high, with four legs, and a large bag is raised at the bottom of the two legs, and there are three small lights flashing on the edge of the stool, and two large bags bulge out on both sides of the stool, like two ears.

Just when Xiao Zhang was surprised, a voice came out of the 'ear' on the left side of the small round stool: "Doctor, what are your orders?" ”

"You two, clean up this garbage, the time limit is one hour, one hundred and fifty pieces per person, whoever doesn't meet the standard, I'll sit on someone's head all day tomorrow, do you hear?" The little old man bowed his head and commanded the two "round stools".

The two "round stool" robots didn't answer first, and the small red light in the middle of the stool emitted a beam of red light, which swept over the damaged cleaning robot, and finally spoke in unison: "Doctor, these garbage robots are just broken down by the microcircuit group, small problems, half an hour to solve." ”

The little old man straightened up and smiled, smiling brightly: "Hehehe! Good! That's half an hour. After completing the mission, I will give you three days off. ”

The two round stool robots didn't ramble anymore, only to see that they each raised their two legs, and the two convex bags under the legs unfolded, stretched out three small silver claws from them, and flexibly turned around to Xiao Zhang's side, a round stool robot took out another nano welding gun from the small box, and quickly lay on the robot maintenance port that Xiao Zhang didn't get an hour to get it just now, and welded it directly without using blue sunglasses.

And another round stool robot stretched out its little paws: "Scumbag, give me the welding torch in your hand." ”

Xiao Zhang swallowed his saliva, and handed the welding torch to the round stool robot in a novel and depressed manner. With that, the first round stool robot had been welded, and it quickly slid to the side of the second damaged cleaning robot.

The little old man waved his hand at Xiao Zhang very proudly: "Inspect the goods, boy, how about seeing the craftsmanship of the old man's grandchildren?" It's only ten seconds, it's not worse than that little Lori. ”

Xiao Zhang took out the computer with a little suspicion, and soon, his mouth opened wide.

In the system, there are four cleaning robots that quickly start to activate, less than ten seconds, after activation, they all get up from the ground, stretch their limbs, and do groups of test actions, with coordinated movements, quick responses, and smooth connections.

Xiao Zhang still didn't give up, opened the repair port of a repaired cleaning robot, and used blue sunglasses to check the welding point.

In that complex world of microcircuits, thousands of nanometer electronic circuits are working vigorously, and the holes that have just been broken are gone, and there is no trace of repair. There is a slight subtle change, though, with many lines having the R character flashing.

"Huo Gong, what does R stand for?" Xiao Zhang was finally convinced, took off his sunglasses, and asked sincerely.

The little old man yawned, stimulated his biological clock, and then pulled Xiao Zhang's arm: "Boy, I'm not a teacher, I'm not obligated to give you popular science, stimulate your biological clock, I'll give you a set of maintenance manuals, it's very practical, not only microcircuits, but also chipsets, communication bionic generators, energy exciters, and even life intelligence controllers, etc., all have detailed maintenance instructions." It doesn't cost anything, it's given to you for free. ”

"Really? Thank you so much! Xiao Zhang was overjoyed, and without hesitation, he activated his biological clock.

The little old man pulled Xiao Zhang's arm and tinkered, and after a few minutes, he let go of his hand, patted Xiao Zhang's shoulder, and said with a pleasant face: "Go to sleep, you have time to study again, you can't eat fat people in one go." ”

Xiao Zhang checked the biological clock interface a little and found that there was one more system maintenance project, and after entering, there were dozens of e-books in it, such as: "Microcircuit Welding Techniques", "Chipset Modification and Repair", "Life Intelligence System Maintenance", "Three Secrets of Excess Blue Light Energy" and so on.

Seeing these maintenance books, Xiao Zhang looked at the little old man in front of him with a smile, and no longer thought that he was just a dispensable hangar manager. In the past, the little old man always called himself "Dr. Huo", but none of the classmates believed it, they only called him Old Man Huo, and the slightly respectful one was called "Huo Gong". Over time, he could only accept the titles of Old Man Huo and Huo Gong, and rarely mentioned Dr. Huo.

"Huo Gong, I also want to ask you a question, are these robots broken down by high-frequency electromagnetic waves?" Xiao Zhang hurriedly asked.

"Of course, three-year-olds can see it, do you need to ask?" The little old man hummed unceremoniously.

Xiao Zhang scratched his head, and continued to ask with a shy face: "I suspect that someone is doing sabotage, although I can roughly guess who did it, but there is no evidence, and I can't go to the door, what do you say?" ”

"Ahem, ahem! There are many ways to learn scum, it depends on whether you want the best or the worst. The little old man's eyes flashed, and he said slowly.

Xiao Zhang was stunned: "What do you say?" ”

The little old man touched his sloppy short beard and cleared his throat: "Okay, the old man reluctantly provides you with three methods to refer to:

First, squat, your cat is in the corner, spend ten days and a half months, you will definitely be able to catch that little ghost, no money. But you should always be mentally prepared to repair microcircuits. 40 yesterday, 300 today, maybe 1,000 tomorrow;

Second, all these garbage goods are eliminated, and the latest model of intelligent robots with defense systems is replaced, no matter how strong the electromagnetic wave is, there is nothing to do with it, and the troublemakers will naturally not be withdrawn. It's just too expensive, I heard that there are tens of thousands, and you can't afford it.

Third, upgrade the system, add a unique solid-state memory to the body of these junk goods, and then implant some programs, such as a small tracking system, which is not expensive, and it will only cost thirty or fifty yuan to upgrade one. 1,000, only 350,000, it's a good deal. ”

After the little old man's words were finished, the courtyard was silent for a long time, and only the sizzling sound of the welding torch was heard.

Xiao Zhang finally understood, this little old man was trying to squeeze his own oil and water. After talking for a long time, it is nothing more than wanting him to upgrade the system, and it is certain that the little old man has this system himself, and maybe he only needs a little action of the "round stool" robot to complete the upgrade.

Sure enough, thirty seconds later, the little old man couldn't hold back: "Hehe, don't believe it, I can upgrade you ten for free, if you're lucky, these ten robots may be able to help you catch the little ghost......"

"Just tell me straight, how much?" Xiao Zhang rolled his eyes.

The little old man grabbed the chicken-nest on his head, muttered for a few seconds, and said, "Thirty thousand, it's all done." ”

"Ten thousand, I want to know the source code of this tracking system." Xiao Zhang unceremoniously cut two-thirds of the price, he thought that he was ruthless enough, and he could get thirty or forty yuan just by adding a piece of solid-state memory.

However, the next second he regretted it.

The little old man grabbed his arm and laughed again and again: "Quack! Scumbag, it's up to you, the old man is so poor now that he can't open the pot, and it's not a matter if some of the inventory he collects is rotten in his hands, and he can earn 10,000 is 10,000. Sign the contract! ”

Xiao Zhang slapped himself on the forehead, and the words were already out, and he was embarrassed to take it back, so he had to reluctantly sign the second contract to sell his body tonight with a shy black face.

After completing the formalities, the little old man happily pressed the second button on the mini remote control, and a few seconds later, two bench robots ran out of room A01 again, with a large bag of various types of solid-state memory removed from there on the stool, and ran straight to the small courtyard of Xiao Zhang's house.
