Zhang Nan's meaning, Chen Jin understood.

Because Zhao Xin is about to be upgraded to become a father, the car can't be racing, dangerous things can't be done, and he, an unruly prodigal son, has to return to the role of "a woman's good husband" and "a child's good father".

Zhao Xin, a man who has been debauched for 25 years, has to become mature and steady, and he cares more about his small family.

Maybe...... When his children grow up and learn to listen, Zhao Xin may proudly tell about his demeanor when he was young, and look forward to the glorious moment when he won the title of "car god" in the eyes of the children.

I thought of this scene in my head.

Chen Jin was shaken all over his body.

A voice in my heart said, "I don't want it!" It's horrible! ”

Zhao Xin, who was sitting across the table, was indifferent, and used chopsticks to clip a dish for his wife Zhang Nan.

Chen Jin: ......

……

Far beyond Zhao Xin's expectations.

Chen Jin, who said that he wanted to learn some car repair skills, insisted on it for seven days in the maintenance garage of the 4S shop.

The learning attitude is very correct, not afraid of hardship, not afraid of tiredness, serious learning, and successfully achieved a quick start.

Even on the sixth day, he helped Master Sun repair a broken Tesla Model-S, and it took a lot of effort.

Master Sun was impressed by him, and said in front of Zhao Xin in private: "I have seen those who are more serious than him in learning to drive, but there are not many apprentices who repair cars with me who are so serious as him...... Boss, didn't you say that his family is rich, just come over and have fun? ”

Zhao Xin opened his mouth, his eyes were full of surprise, and he spread his hands helplessly: "How do I know?" This kid wasn't in this style before. ”

On the eighth day, Chen Jin didn't come over much.

On the planet Helfa, he devoted himself to the vigorous transformation of the expedition vehicle.

There are actually several difficulties in this work.

The biggest difficulty is how to transfer the agricultural machinery truck in Tris City to the Dakeng camp?

The weight of an agricultural machinery vehicle is about ten times that of an ordinary family car, weighing more than a dozen tons.

After thinking about it carefully, Chen Jin took two measures.

One is to increase the number of robots and expand the number of robot exploration teams from two to four.

The total number of robots rises to 20.

Each robot can move 200 kilograms of goods, and 20 robots can work together to lift seven or eight tons of goods.

Secondly, the agricultural machinery that should be a combine harvester, although it is bulky, but it is also composed of multiple module components, disassemble those modules with lighter weight, and carry them separately, except for the motor and transmission module, other modules, the robot can be transported back to the big pit camp.

Remaining components that are difficult to disassemble, such as tires, chassis, electric motors, gearboxes...... With a weight of about five or six tons, it was pulled by the Blue Angel in front and pushed hard by more than a dozen robots in the back, and it took more than two days to slowly move into the Dakeng camp.

When Chen Jin finished learning vehicle maintenance and returned to the Dakeng camp, the parts of each module of the combine harvester were all placed in front of him.

The price is: the robot is vigorous, the power in the body is basically exhausted, and the power of the Blue Angel has also dropped below the safety line, and all of them are queuing up next to the charging pile to be charged.

Subsequently, the more difficult work was placed in front of Chen Jin.

How to repair and modify this combine harvester with a length of 9 meters, a height of 4 meters, a width of 4.5 meters and a total weight of about 13 tons?

It took about half a day for Chen Jin to think about and determine the modification plan.

The first is to do subtraction, remove the harvesting device on the body of this harvester, such as the front harvesting drum, which can be removed; The intermediate conveyor belt and threshing device can be removed...... Most of the devices related to agricultural harvesting functions can be castrated.

After some subtraction, the weight of the harvester will drop to about 10 tons.

The barn at the rear has been converted into a large cargo compartment that can hold a lot of things and make it easy to explore.

In addition, a bucket must be installed in front of it, in case of any roadblocks, it can be cleared to enhance the passability of the expedition vehicle.

There are also cable pulling devices, emergency self-rescue devices, water pumping and fire extinguishing devices, backup power generation devices, etc...... These things must all be added and prepared to increase the safety factor of outdoor adventures.

So in the next half month, Chen Jin's work focus was all on the transformation of the expedition vehicle.

It took a lot of effort and money to finally complete the repair and modification of the expedition vehicle.

An expedition vehicle named "Expedition No. 1" was placed in front of Chen Jin.

After the exterior is sprayed with a layer of silver paint.

The "Expedition No. 1" in front of you is tall, mighty, elegant and full of industrial beauty.

He let out a long sigh of relief.

Chen Jin crossed his waist with his hands, and his heart was full of emotion and a sense of achievement.

In the past half a month of modification work, in order to get this "Expedition No. 1" right, he has solved countless problems, large and small.

For example, the problem of tire matching, the four tires of the Expedition 1 were rotten to the point that they could not be used, and the city of Tris could not find good tires to replace, so they could only buy them from the other side of the earth.

The problem is that the tires used by Expedition 1 are 1.5 meters in diameter, and the diameter of the portal is only 1 meter, so the full tires can't fit into them at all.

At this time, Chen Jin could only consult Zhao Xin and ask if there was a tire that could be assembled, and could combine multiple small tires into one large tire?

"Uh~ This kind of tire, it doesn't seem to be there." Zhao Xin shook his head.

Master Sun on the side interjected: "I have heard of a kind of tire, it is not made of multiple pieces into one, but by a circle of thin tire skin, stacked together to form a large tire, a bit similar to a solid tire, does not need to be inflated, will not burst the tire, the disadvantage is that it is more bulky." ”

"Yes, yes, that's what I want!"

Chen Jin was very excited, and under the guidance of Master Sun, he contacted a factory that produces modular tire leather and put forward his needs.

But the tire leather produced by that factory does not have the size that Chen Jin needs, and the factory will not open the mold for production, unless it receives an order of more than 2 million yuan.

"2 million, I'm out! But I'm going to get the product I need in five days! ”

Chen Jin gritted his teeth and said, isn't it money, he has it!

The director of Song was stunned for a moment, and then patted his chest and promised: "After five days, I promise to let you see the product!" ”

Five days later, after the quality of the combined tire leather was produced, Chen Jin took it to the Dakeng camp and wound a circle of thin tire leather into a large tire, the size of which fully met the needs.

Then glued with special industrial strong glue, the tire quality will not be too much worse than conventional tires, and there is no need to worry about punctures.

So far, the expedition vehicle has been basically modified, and it has been driven around in the big pit, which is very stable, and the acceleration and deceleration performance is very good, which can definitely meet the preferences of heavy vehicle enthusiasts to "drive a big car".

But new problems arise.

Energy is insufficient.

There are a total of 100 large high-energy batteries in the battery compartment of Explorer 1, which is 10 times the size of the Blue Angel's body!

It can charge more than 3600 kWh.

Even if the 30KW output power of the charging pile is used to charge the Expedition 1, it will take five days to fully charge.

But the robot also needs electricity, and the charging power cannot be all given to Expedition 1.

The problem of insufficient power must be solved immediately!
