Today's engines are complicated, consume a lot of energy, have a large volume, and are inconvenient.

The dog should say, choose an engine part, and select the available ones for assembly; Lines are reorganized, and unnecessary lines are disassembled.

"Master, the engine is too large and requires you to refine it with mental power."

"Bring it."

"Yes." Dog eggs clean up the parts that need to be refined and send them in.

Zhong Yuxiu put down the work at hand first and refined the parts one by one, the shape of the parts has not changed, but the size has changed; When the parts change, the size of the shell will also change, and Zhong Yuxiu re-planned the size of the shell and drew a drawing and handed it to the dog.

"Pick it up and give it to Hao Nan, he knows how to do it."

"Yes, master."

Dogan took something and turned to go downstairs; The sensor sensed Hao Nan's location, and went straight around the living room and out of the small building; Hao Nan and Tian Shangguo were training outside to fight, and although they had to follow and protect the characters every day, they couldn't fall behind in training.

"Didi." The dog gave a warning and signaled that it was coming.

Hao Nan and Tian Shangguo looked back when they heard the movement, and they all stopped, "Dog, why are you here?" ”

Goudan stepped forward, handed him the paper in his hand, turned around and walked away.

Hao Nan looked at the dog who walked into the small building, and looked down at the drawings again; When you see the above parts, model terms, busy covering your chest.

"What is it?" Tian Shangguo was aroused by curiosity.

"It's Comrade Zhong's blueprint, I need to go out, you look after the house." Hao Nan hurriedly went to the house to change his clothes, and when he came out, he said, "Let Sister Li send some fruits and other things to Comrade Zhong, and I also need snacks." ”

Tian Shangguo nodded, "Got it." ”

Li Yun heard the voice, "Where are you going?" ”

"I'm going to go out, you remember to send snacks and fruits to Comrade Zhong; She's busy at the moment, just knock on the door and say a word. Hao Nan threw off his coat and put it on, tied up the standard gun, and walked away like the wind.

"In such a hurry, what are you going to do?" Li Yun was puzzled.

Tian Shangguo shook his head, "I just know that it is a drawing given by Comrade Zhong, and I think it is going to be used." ”

"That's it!" Li Yun thoughtfully cleaned up the kitchen, brought the prepared snacks, and went upstairs with the newly delivered fruits in the morning, "Knock knock, Comrade Zhong, I'm here to bring you snacks and fruits." ”

Zhong Yuxiu's ears moved, "Dog, go get it in." ”

"Dididi......." Goudan walked to the door, opened the door and stretched out his hand.

Li Yun glanced into the room, which was tightly covered by the dog's mechanical body, and he didn't see anything; The tray was put into the dog's hand, "Comrade Zhong, don't just focus on studying things, the body is the capital of the revolution; Remember to eat snacks and fruits. ”

Dogan held the tray with one hand instead, closed the door, and returned to the laboratory.

Zhong Yuxiu frowned and said in a low voice: "What's the matter with this Sister Li, she often comes upstairs to hang around." "Her room doesn't need to be cleaned, and the dog can wrap up the second floor.

"Master, Li Yun is still outside." Dog Egg controls the volume to a minimum.

"What does she want to do?" Zhong Yuxiu took a deep breath, "Did you send her to find out what I was doing?" It's not like that! There are Hao Nan and Tian Shangguo, and they don't need her at all. ”

Goudan said: "It's not the one sent from above to find out your details, it's a spy." ”

Zhong Yuxiu nodded lightly, didn't speak again, and devoted herself to scientific research; The engine problem was solved, and the data was calculated three times, and the plan was decided. Turning her head and going to calculate and study the sensor, the sensor's sensor of the robot is a bit big, she wants to apply to the sensor of the car, and at the same time, how to install a chip in the sensor and then enter the map is also a big problem.

Nowadays, there is no Internet to talk about, and it is not practical to connect with satellites.

For this reason, Zhong Yuxiu had a headache for two days, until Yan Lao sent the shell of the car and the lithium battery, and the generator shell sent by Hao Nan; She put it down for the time being, and studied the lithium battery, how to make it to the extreme, can be used repeatedly, and use it with high power.

Due to limited materials, Zhong Yuxiu spent more than half a month to shrink the lithium electron to the size of a fist; It can store up to 500,000 milliamps, which is the best she can do. If the material is better, it can reach hundreds of milliamperes of storage power, then it can be used for a week, and now it can be used for up to three days.

"That's it for now." The conditions did not allow it, and she could only do her best.

Zhong Yuxiu put down his things, and turned his head to study the sensor and the chip, wanting to combine the two; She spent another whole month, during which she never went out except to go to school to order, eating and drinking in the laboratory, Li Yun sent it, and the dog egg was responsible for picking it up.

"That's it!"

The dog's mechanical head writhed. "Congratulations to the master, the research and development has been successful, from today onwards, you are also a car owner."

Although this car is too rudimentary, it cannot be compared with those flying cars of the interstellar age.

"Tongxi, I owe your success to you." People say that it is difficult to go from luxury to frugality, which is really the case; The ones used in the interstellar are the best, and everything back here is the simplest and inferior, and it's not easy to study.

Yes, in her case, these materials are just inferior.

"Does the host want to have a big meal to celebrate?"

"You're cooking?"

Dogan said, "Okay, master; Make you love Dongpo meat, fish-flavored shredded pork, and kung pao chicken. ”

"Go quickly, my saliva is coming out." I stayed in the research room for nearly two months, and although I ate and drank well, I didn't have the heart to eat properly.

"Yes, master, I'm going."

Dogan walked out of the laboratory on his mechanical legs and went downstairs to the kitchen; Li Yun was startled, and said in a lost voice: "Dog?!" ”

"Didi, Didi."

Goudan didn't speak, passed her to check the ingredients, and then pushed out of the kitchen and closed the door; Began to prepare the soup and ingredients, the host worked hard, and he had to be treated.

Li Yun looked confused, and he didn't know what to do.

"Sister Li, what's wrong?" Hao Nan and the others heard the movement and came over, and saw Li Yun standing outside the door.

Li Yun's snort moved slightly, and he turned around and said, "Do you know who is inside?" ”

"Comrade Zhong came out? Then why kicked you out? "Tian Shangguo has no waves.

"It's good if it's Comrade Zhong," Li Yun said angrily: "Dog Egg, it's a robot dog egg developed by Comrade Zhong; I was pushed out when I went in, and I didn't know what to do; My soup is still stewed, don't let it dry for a while. ”

Hao Nan was noncommittal, "Dogan is a robot, and there is no independent thinking....... how can he push people out.

Li Yun: ........

"Sister Li let me." Tian Shang National Road.

Li Yun moved to the side, if she didn't believe it, she could still tell this kind of lie?

Tian Shangguo gently opened the door and looked inside, Goudan was busy with his mechanical hands, and his cooking skills were not inferior to humans, and he was shocked.

Dogan sensed that someone was coming to check, but he didn't look back, and the speed of his hand didn't slow down; It's just that the movements are a little stiffer, and the limbs don't seem to be coordinated by humans.
