In a rental house, Zhang Tao is playing the most popular game at the moment, the keyboard is pressed wildly, and the mouse is flying. The pen "Fun" pavilion www.biquge.info body sways from side to side with the game characters.

“ACE！” The computer screen shows Zhang Tao's record.

"I'm number one!" Zhang Tao slapped the table with his excited palm, and the second-hand computer desk bought from the thrift market cracked. "My more than 200 dollars!" The water cup on the table was also shaken, and the water flowed out, Zhang Tao hurriedly wiped the table with a rag, and the water flowed down the crack of the computer desk into the socket, and a blue current rushed out of the socket and flowed down the water to Zhang Tao's body, and Zhang Tao was tragic.

"Huh? Didn't I go to see Marx? Where is this? Zhang Tao looked at the white and tender face in the mirror, as well as the long-lost biceps muscle, and determined that he was reborn. Looking at the furniture and furnishings in the rental house, I determined that this year was 2007, and I had just graduated from university and worked in a company in the capital for more than half a year.

In my previous life, I lived a boring life of two points and one line every day, and I had enough of it, and there was no way to make a living. I must live a wonderful life in this life.

"What should I do?" Zhang Tao thought. Stocks! No, I don't know which stock will go up. Lottery ticket! I bought it twice, I didn't hit it once, and I didn't buy it. It's okay to get five yuan, and my brother's requirements are not high. Flip the house! OK! If you don't have capital, you need capital to do everything.

I'm doing a business without a book, I'll go home and pick mushrooms, and I'll do it. I remember that in my previous life, the world had already made an electronic dog to replace the search and rescue dog, and I had studied the principle for a while. If I had invented an animatronic dog to find mushrooms, wouldn't the mushrooms, matsutake mushrooms, monkey heads, and reishi mushrooms on the mountain all be mine? When the time comes, the money will flow into the pocket. Ha! Ha! Ha!

Wiping the words on his lips, Zhang Tao straightened his collar in front of the mirror, found a piece of paper and notes what he wanted to buy in a while.

First, go to the wholesale vegetable market to buy some mushrooms that are common in the mountains and markets, and after researching and making soup, you will not waste it. Matsutake mushrooms and reishi mushrooms are too expensive. Then go to Wujiaohua Building to buy resistors, capacitors, diodes, small transformers, batteries, relays, a roll of copper wire, a roll of solder, a box of solder paste, an electric soldering iron, a multimeter and a small motor, and a set of electrician tools. Test tubes and beakers also have test strips. Magnifier, microscope, monitor, CPU, mouse, keyboard.

Zhang Tao went to the market and bought a lot of things, and brought them back to the rental house in large bags and small bags. After spending half a year's salary, I will go to the company tomorrow to quit my job, and we won't do the work of serving tea and pouring water, didn't Grandpa Deng say that science and technology are the first productive forces! Let's go and do the business of the first productive force.

On the way home, I caught a few ladybugs on the side of the road, and it is said that a female ladybug emits a smell, and the male ladybug can smell it from 20 miles away, so he rushes to mate. It's not bad to study ladybugs as well.

When I went back to the rental house, I took out all the things, and the mushrooms were hazelnut mushrooms, and the hazelnut mill could not be cultivated, and the price was medium, so it was suitable for my own research. I took out the hazelnut and smelled it, the smell was fragrant and the smell of fungi was unique, and I tried to smell it far away, but I couldn't smell it at a distance of a few meters from the hazelnut. The human sense of smell is really not good.

When I went out for a walk, I was hungry, so I took out four or five mushrooms from my pocket, washed them, cut them into shreds with a knife, threw them into a pot, put oil, salt, coriander and water, covered them and boiled them. The life of a single man is simple, just familiar.

After washing his hands, Zhang Tao put on insulated white gloves, and carefully took the electronic components out of his pocket and put them on the table. Put the vial with the ladybug on the windowsill, the ladybug will be fine if it doesn't eat for a few days, it will hibernate.

Take out the multimeter, install the battery and the meter pen, and measure whether the resistance and other components are qualified. I checked it all over, and the new goods are good, and they are all within the standard.

Take out the test strip and test the pH, alkalinity! Kindness! As in the experiment done in the previous life, the resistor was taken and broken to an angle with pliers, several solution bottles were opened and poured into the test tube, shaken and poured into the beaker, and after a while, the beaker was full, and the blue solution looked beautiful.

A hole was drilled in the glass groove with a small 5 mm drill bit, and halfway through, the glass shattered. Maybe it's because I haven't eaten. Drill another one after eating. Zhang Tao had long expected this to happen, and bought a few more glass troughs.

The soup in the pot boiled, and a mushroom fragrance wafted out. Zhang Tao washed his hands and took out two steamed buns, broke them into pieces and put them in the pot, and the mushrooms were good for soaking in the buns. Great and affordable.

After eating, Zhang Tao continued to drill holes, drilled slowly for an afternoon, and drilled well. Solder the modified gas resistor with a thin copper wire, insert the other end of the copper wire into a glass tank with blue solution, and then connect the capacitor, battery, transformer, light-emitting diode, CPU, monitor, mouse, and keyboard.

Zhang Tao clapped his hands, and it was done, and then it was up to him to see if the memory in his mind was right.

Turn on the power display and light up, there is a white X and Y axis cross line in the middle of the screen, and it is dark around, normal. Then open the blue solution tank, only to see that the upper layer of the blue solution gradually turned purple, and as the purple spread to the bottom of the solution, the upper layer of purple solution gradually turned from purple to red. The two-quadrant area of the monitor shows a large red blob, which flashes from dark to bright.

The erythema flickering is a matter of the solution, and it is good to purify the solution. This is easy to do, and it should be better to buy some good solutions on the market. Test the distance, Zhang Tao picked up the bag containing the mushrooms and walked away, and when he walked to the door, the red on the screen disappeared and turned black, the distance still needs to be improved, it seems that the next step is to study ladybugs.

It's getting late, let's go to the Wujiaohua Building tomorrow to buy a better solution, and you can also get a sum of money to buy a memory and CPU to solve the problem of three-dimensional imaging of the display. A CPU can't handle too complex images.

The next morning, I got up and had breakfast, went to the company to quit my job and settle the bill, there is no shortage of talents in the capital, I will have a doctor in the morning, and I can have a doctor in the afternoon, not to mention Zhang Tao, an undergraduate, so Zhang Tao explained the situation and settled the salary.

I went to the Wujiaohua Building to buy a high-grade solution, and I went to the computer city to buy a memory. It's all brand new, and the old ones can be used, but the resistance value may drop, so it's still not risky. After thinking about it, I bought a spare USB flash drive, in case the things that were delivered back to my hometown were broken, I could look at the information in the USB flash drive.

When you get back to your rental house, connect your CPU to your storage, USB flash drive, and monitor. The solution has also been replaced with a high-grade solution. The image on the monitor has become a three-dimensional image, the red spot in the two-quadrant area has become several small red dots, and there is an H-axis that shows the height between the X-axis and the Y-axis.

Zhang Tao picked up the bag containing the mushrooms again and walked to the door, the red dot on the monitor did not change, it was successful, and now it is up to the ladybug's sensory research.
