On that day, the boys had just returned to the base after reading the book from school. They were familiar with the various environments of the base and suddenly found that there was some fresh soil on the edge of the base wall. Everyone looked at each other and was sure that they had never done such soil work. So they came all the way to the birthplace of the soil - in front of a hole next to the factory, with curiosity.

When you walk to the edge of the cave, the first thing that comes into view is a bunch of toy cars busy back and forth on this "construction site". These toy cars include excavators and mud trucks. Each large toy car is doing their own work in an orderly manner like a person driving. Two excavators are loading one claw of dirt onto the mud truck. After filling a car, the mud truck drives it drippingly to the wall and pours the soil in the truck's bucket on the corner of the wall. The whole scene is like a human construction site that has been reduced by several times.

"Damn, what are these things?" The curious first mate and the ashes intercepted a mud truck passing by, and picked it up regardless of the soil on it falling on their feet. What surprised them was that there was no shrinking human and no alien creature in the mud truck driving inside. The empty cab made the boys full of questions.

"I guess this was something Budi made... The most I made two days ago was to modify some small mechanical equipment..." Duan Guoyu took over the mud truck. Unlike the big pair of dust machine, he only looked at the cab. What he paid more attention to was its mechanical part. He noticed that the power used by this mud truck was the modified electric power drive, and a familiar energy block replaced the fuel tank that should have been installed there. However, the dump system of this car was not too heavy because the load was not too large, so it did not use a hydraulic system. Instead, the traditional mechanical top arm simplified the chassis system at the bottom. Looking around, the original plastic bucket and mechanical arm on the excavator were replaced with metal parts.

"Go to the factory Qiuqiu..." The strange scene successfully aroused the boys' curiosity. They put down the mud truck and other toy cars in their hands, and trotted towards the factory. However, when they put down the mud truck, Duan Guoyu noticed that the emptied mud truck, which had been basically emptied by accident, did not continue to drive towards the corner of the wall like the automatic control of the program, but turned aside and returned to the excavation site to queue up to load new soil; while other mud trucks did not drive directly when passing through this pile of soil obstacles. Instead, they automatically avoided the obstacles and drove around...

"Hehe!! Are you back?" Before the boys entering the factory were shouting and looking for Budi, they saw a familiar Bala bear's head drilling out of a pile of toy vehicles.

"Damn, what are you doing?!" The most curious gray machine rushed to Budi and asked impatiently.

"Be careful! Be careful! Don't ruin my car!!" Budi reminded Gray Machine to pay attention to his feet. At this time, everyone discovered that there was a modified large all-terrain toy car on foot. Budi climbed his clumsy body onto the somewhat weird all-terrain car. The special seat on the vehicle immediately stretched out the lock to connect its body and the vehicle. In this way, under the gaze of everyone, Budi controlled the all-terrain car with each wheel that was the size of a fist and suddenly accelerated, and ran around the factory. Although the all-terrain car was a toy car, the speed and sensitivity of this all-terrain car were quite high. Under Budi's precise control, it could even make a series of special driving skills such as tail swing and high-speed turnover. Moreover, it was not dragging at all when passing through various obstacles. Its accuracy was comparable to that of a special driver like a first mate.

After walking around the factory for three times, Budi then controlled his car to rotate and drift accurately at the feet of the machine. Looking at the machine who was startled by being startled. Budi smiled at the first mate with a smug smile: "How is it, my driving skills are no worse than you..."

"Not a lot!" Without waiting for the first mate to answer, the ashes who were shocked by Buddy were naturally unhappy with it's so proud and hit it. He pointed to the one-meter-high workbench and said disdainfully: "This thing can only run on the ground. When you encounter such obstacles, you will have no choice! And don't forget. Not only workbenches, but also stair obstacles like stairs!"

"Hehe..." Seeing the grey machine belittled his car like this, Budi did not directly refute, but just smiled and pointed his little paw towards the workbench: "Go forward!!"

Under Budi's control, the all-terrain toy car drove to the workbench at a constant speed. Just as everyone was wondering whether Budi was going to fly up or jump up, they saw that the suspension system of the all-terrain car was growing magically. In less than two seconds, the body of the all-terrain toy car was already so high than the workbench.

Before the boys were amazed at this strange way of lifting, the four wheels supported on the ground operated simultaneously to move the car body forward, and the strange suspension column supporting the car body tilted forward, steadily supporting the car body on the workbench. What made the boys curious about was that the strange suspension column seemed to have a certain flexibility. When touching the workbench, it could not only bend at will, but also immediately contracted after the car body was sent to the workbench and retracted, and the four large wheels on the ground strangely retracted like a yo-yo... The whole process was not only extremely incompatible with the principle of mechanical transmission, but also extremely beyond the boys' imagination.

"Hehe... This is my new car, named Tour No. 1!"

Seeing the boys surprised, unbelievable and other expressions, Budi was very satisfied with the psychological effects his new car brought to the boys, and then he explained to the boys the various new scenes they saw.

"Not to mention the traditional part of this thing, the most critical position is that I used a new generation of biochemical muscles, which replaced parts such as transmission and suspension systems. Not only can it greatly enhance its ability to pass, but it can also directly climb over vertical obstacles. In the future, you won't have to hold me under your armpits and run around. I can also go to the base when you are not there. In the future, I will also redesign the Tour No. 2, and directly suspend it with an ion thruster at the bottom." Budi patted the all-terrain vehicle under his body and said that he was quite satisfied with its ability to move. Indeed, with this thing, Budi's ability to move will definitely be greatly enhanced; and if the so-called Tour No. 2 is really transformed as it plans to do in the future, then the thing doesn't have to consider ground obstacles or other things...

But Duan Guoyu was very sensitive to a word in Budi's words - a new generation of biochemical muscles. Has this thing made a new breakthrough? But before he could ask about this situation, Huijie suddenly remembered the construction machinery toy cars outside that automatically dug holes and asked: "What's going on outside?"

"Outside? Are you talking about those engineering cars? That's when I transformed some of the engineering machinery, and then used a super central processing unit to make a clone, and controlled them to start digging an underground base; some equipment development and production still require a special environment, and don't you think everything is too crowded and casual in the factory and warehouse? Old Duan knew about the plan for this new base... Time was too tight so I didn't have time to redesign the automatic engineering robot, so I directly modified the toy cars I bought outside..."

Duan Guoyu knew about the plan for the new underground base of Budi, but he originally thought that he would dig it by himself after everyone finished the exam, but he did not expect that Budi would actually make such a thing and start digging automatically.

"You made it yourself? Brother Duan has been reading a book a little longer these days, but he didn't help you get the parts?" Zhen Lan, who was very familiar with Budi's previous workflow, was a little strange because he also noticed that the transformation parts of the toy machinery was not easy to get so many metal parts.

Seeing Xiao Zhengta's puzzled little face, Budi smiled and took a sneering smile to take pictures of Zhen Lan's expression. He manipulated the car to a device placed on the workbench, picked up a few pieces of scrap iron and put it into its feeding mouth, and used the modified wireless network to control the computer screen. At the terrifying calculation speed of the super central processing unit, he quickly made a 3D model of Zhen Lan's face shape on the screen. After clicking the red button after translation "production", the equipment was humming, and the scrap materials were quickly decomposed. The metal molecules, atoms and even smaller units were in the equipment's operation.

The control was accurately combined together, and a metal face model or parts appeared on the processing table of the equipment. The boys saw that this face was exactly the same as the expression Zhen Lan had just photographed, and even the tiny metal hair such as eyelashes, eyebrows and small velvet on the mouth were made with slight exposure. Seeing this boy, he knew where Budi got so many metal parts, with such a powerful automatic parts processing machine, or metal 3D printer... All parts only need a drawing to be produced immediately! Unless their size exceeds its production and processing capacity!

The person who is most happy to see this scene is naturally Duan Guoyu. With this equipment, it means that he no longer needs to slowly produce parts on the fitter table one by one. This will greatly improve the research and production speed of the equipment, and also have a lot of time to do more training for himself. He and the boys only need to assemble these parts, and a set of equipment will continue to strengthen the boys' strength.

"Hehe, there are more fun things..."

Budi waved and controlled his car to take the boys to the other side of the workbench...
