Since the revolutionary progress of graphene battery materials, all kinds of all-electric driven machinery and equipment have begun to sweep the market rapidly at low prices, driving the traditional fuel drive method out of the territory that was once firmly occupied, and can only survive on some special occasions. Pen, fun, pavilion www. biquge。 info

That's why Ye Tianlong's caravan can run around with solar-powered charging vehicles without worrying about losing fuel supplies.

However, in the current era, the remaining scientific and technological level around the world is actually quite uneven, and there is no large-scale manufacturing capacity like in the pre-industrial era. Even for a large caravan like Ye Tianlong, the main mode of transportation still relies on animal power, and it does not have the ability to use mechanized transportation.

In fact, Ye Tianlong never thought that he would see a vehicle that could move himself in such a remote and small place.

Now looking at the crane that appeared in front of him, he was dumbfounded, and it took a long time to remember and ask Huo Si, "Is this Cheng Bin's caravan?" ”

He knew that Cheng Bin's caravan had already gone north, and if they came back early, it would be reasonable to appear in this direction.

Huo Si looked at the two people in front of the crane dumbfounded, and said with a wry smile: "It's not Cheng Bin, it's our people." ”

"Our people?" Ye Tianlong was stupid and couldn't tell the difference, and repeated: "Why don't I know each other? ”

"Because it's our people." Huo Si accentuated the word "we", and in order to cooperate with the explanation, he also pointed to himself and then to the apartment, and then waved his hand at Ye Tianlong, "It has nothing to do with you." ”

Ye Tianlong then remembered that the man next to him was not his subordinate, and the "we" he said really had nothing to do with him.

Since Hoss recognized that the two people walking in front were Zheng Yu and Rogge, of course, he immediately guessed who was sitting in the car behind. In fact, if it were a different person, he might not be able to believe what he saw in front of him, but since it was Ding Chen, it seemed that even outrageous things would become possible.

After receiving the news that the alarm had been lifted from Hoss, and finding that the car had no offensive power, the people in the caravan also relaxed, except for the person on the guard duty, who was still vigilantly watching the approaching armed men, the others gathered together in twos and threes, looking at the slowly approaching crane, guessing the origin of this thing.

The people of the caravan are out all the year round, and they have seen more from south to north, so they naturally know what it means for this scene in front of them to appear at an ordinary gathering point, or they have picked up a car that can still be driven, and the battery on this car still has electricity. Either someone has restored a car from the past and found a way to recharge the battery.

The probability of the former possibility is negligible, and if it does appear, it can already be used to write a novel, and maybe it can be used on an omnichannel or something. But although the latter possibility seems more reliable, if it occurs in an ordinary gathering point with a serious fault line in knowledge, it is even more shocking than the previous possibility, and the degree of unreasonableness can simply make people shout "If you don't blow it, you can die". After all, doing all this from scratch, and putting it where they came out, it also requires a top-level maintenance team.

The most important thing is that there are only a handful of places like the cities they came out of, which still retain a lot of technological heritage and can still claim to be a civilized world.

Compared to this speculation, the two young men and women who appeared on the road with fully automatic rifles are simply not worth mentioning.

Compared with the caution of the caravan, the people in the apartment were much more welcoming. Rogge's popularity is not good for the time being, but Zheng Yu is a native of the apartment, and the star of tomorrow is his son properly. Not to mention Ding Chen, he never stopped when he arrived at the apartment, and in more than a month, he not only helped Ye Dai make so many things, but also successfully captured the hearts of beautiful women. Now many people look at Ding Chen, and they already have the mentality of a mother-in-law looking at their son-in-law.

Now that my own son and son-in-law have come back with things, of course everyone is not welcome, and everyone comes out to watch.

Huo Si was the closest, and he didn't care about accompanying Ye Tianlong at this time, so he trotted all the way over, met Zheng Yu and asked, "Where did this come from?" ”

Zheng Yu thought he was asking about his rifle, and proudly patted the barrel of the gun and said, "I found it on the mountain." ”

Hoss gave him a pop directly, "I asked about the car. ”

Zheng Yu touched his head very aggrievedly and asked Rogge, "Why do you all like to hit me on the head?" ”

"Because you're stupid." Rogge said. Then she asked Hoss, "Who are those?" ”

"A caravan from the south." Hoss said. Then he told Rogge, "Don't deal with those guys. ”

"Why?" When they saw the cars and solar panels on the road just now, Zheng Yu had already told her that it was a caravan. However, this was the first time that Rogge had seen such a large-scale caravan, so he confirmed it with Hoss. Hearing Hoss's warning, she felt a little strange: "Could the caravan offend the locals?" ”

Huo Si smiled bitterly, of course, the caravan would not offend the locals, but Ye Tianlong's caravan was too strong, and if something really happened, it would be difficult to pursue it, so the measure taken here in the apartment was to clear the wilderness. Fortunately, Ye Tianlong is not Su Ying, so he usually doesn't stay here for too long.

He didn't have the will to explain to Rogge, looked up at the crane, and just in time to find Ding Chen sitting in the cab waving to him

Hoss asked, "Why is he walking so slowly?" ”

Hoth and Luther had seen caravanserai of electric vehicles, not to mention that even the bulky solar cell car could run much faster than the crane.

This question Rogge had discussed with Ding Chen several times, so he pointed to the crane very happily, "See for yourself." ”

Hoss was shocked just now, and at this time he really looked at the car in front of him carefully, and then found the difference at a glance.

Poor Hoss didn't even know there was a word for chaintracks.

"What is this?" He was stunned and asked, "How is it iron...... Wheel? ”

"Be quiet." Ding Chen leaned on the window of the car and shouted, "Beware of forbidden words." ”

Thanks to the all-electric drive, the noise of the vehicle is very low, so he can hear Hoss's words clearly.

Like the chain rail, Hoss didn't know what the forbidden word was, so he directly classified Ding Chen's words into the ranks of intermittent madness. He looked at the three of them, and finally stopped his gaze on the relatively reliable Rogge, waiting for her to explain.

Rogge sighed, motioned to Hoss as he walked, anyway, the crane can't go fast, and the remaining more than 100 meters is enough to explain.

There are only two people to maintain such a large power plant, and of course the maintainers can't be allowed to run around the mountain on their legs on weekdays, especially if something goes wrong, do they still let them run with parts? So there are definitely the necessary vehicles. In fact, in addition to this crane, there is also an all-terrain type vehicle and a trailer.

However, these cars do not have the treatment of the machinery in the apartment warehouse, and those agricultural machinery are sealed and stored in a plastic sleeve, and these vehicles are parked directly in the warehouse, many metal parts are rusted and rotted, and one of the axles of the all-terrain type car is even rotten.

During the time that Ding Chen stayed on the mountain, he mainly chose a usable battery and demolished the east wall to make up a car that could be driven.

Compared with the all-ground type car, this crane can be very expensive because it is an engineering vehicle, so in order to reduce weight, the body is made of a large number of lightweight composite materials, and the degree of rust is the lowest, so it has become a preferred choice.

Ding Chen can use the gear set of the thresher to assemble the gearbox in the apartment, and it is easier to repair the vehicle with a modular design by replacing it. In fact, it didn't take much effort to even solve the power supply problem. Although he can't solve the high-voltage transmission fault, it is still very simple to find a fan that can still generate electricity, and then repair a set of rectifier filters to charge the on-board battery.

What really gave him a headache was the lubrication of the mechanical parts and the aging of the tires.

There are a large pile of sealed and preserved phospholipid soft oils in the warehouse, and you can pick them up for emergencies. This is also thanks to the simple structure of the electric drive car, if it is a fuel car, he really can't solve the problem of high-temperature lubricating oil for internal combustion engines.

He really can't help it when the tires are aging. The tires of these cars have been left for so many years, poke a hole with your fingers, and drop the slag when you touch it, and it is estimated that there will be only wheels left when you drive out of the warehouse.

Fortunately, Ding Chen later found two wheels as spare parts, which solved half of the problem. Then he found that in order to adapt to mountain operations, the crane could also be modified to run in a half-track mode, so he really found a way to drive the car back. Of course, he doesn't have rubber pads, so don't expect too much speed or anything.
