As the saying goes, learn well for a lifetime and learn bad things all the time.

Zheng Yi is a innocent and kind surgeon. He really didn't expect that there were so many supplies that could be spoken out.

With Du Bin by his side, Zheng Yi knew what good things to ask for.

"Switch to an ultramicro motor."

Du Bin said: "I find that you rarely use the rogue's maximum speed, with an average speed even below 180 kilometers per hour. The heavy oil engine overflows too much for you. The ultra-micro motor is equipped with a graphene battery, which can allow you to travel 30,000 kilometers per hour at 150 kilometers per hour."

"The road conditions outside are really bad." Zheng Yi said helplessly.

Du Bin expressed his understanding and continued: "After changing to an electric engine, solar energy can be converted into electricity, and you can also use tulips to quickly charge the battery. The biggest advantage of this is that you can free up ≥0.3 cubic meters of space."

"Change!"

It's equivalent to one third of the lattice, what else can I hesitate about?

And it reduces the supply burden.

"Brother," Zheng Yi smiled, "After you say that, can you make a tractor? Just be simple and control the volume."

Du Bin's brain operates efficiently and said: "If you don't have high requirements for various parameters, just control the volume of the items you carry as the first indicator, the small engines produced in our factory are now sufficient. Then purchase assembly modules from Rongcheng, and the tractor is easy to complete."

"There is no need for a tow bucket, I just want the front of the car." Zheng Yi smiled and said, "It is best to control it within one cubic meter. If it really doesn't work, it must be disassembled and installed."

Du Bin said he understood and would draw design drawings tomorrow.

Zheng Yi asked Du Bin to make a list again, it would be best if it was not sold on the surface, so that he could bargain with the shelter.

After discussing for a long time, Du Bin perfected his memorandum and prepared to go upstairs to sleep.

Zheng Yi suddenly asked: "Sanctuary, I mean underground, what are the living conditions of ordinary people?"

Du Bin went down for two seconds and said: "Life is more regular and diet is more abundant."

“Is there a big difference with the surface?”

“Very big.”

Zheng Yi ended the conversation, lay on the bed, and thought of a hierarchical society with abundant supplies but everything was cold.

As you can see from the trip to the air city, the shelter is full of crises and pressure, but it is not difficult to maintain a wealthy life for a few people.

The so-called surrender of rule is probably just the wishful thinking of people like Lin Shihong.

What the shelter really needs is a luxury goods trade object.

Think about it, with the current technology and construction capabilities of the shelter, most of the surface can be closed to form an ecosystem.

The reason why they didn't do this is mostly to launch nuclear strikes on the surface at any time.

This is a world that is trapped in crazy war.

Zheng Yi soon fell into a deep sleep.

When he woke up, the surroundings were still quiet.

He simply returned to the gray fog, moved a pig and a bucket of water, and distributed it to the grandchildren of the Ban family and Lao Wei of Rongcheng as a gift.

If it happens, you can also give me one.

These friends maintain the bond between Zheng Yi and this wasteland.

After optimizing the map, the journey from Rongcheng to P203 was shortened to eight hours, and both parties can also transmit electronic files.

Lao Wei, who had Sequence 4, was in charge, with more than 200 disciples and upgraded production equipment. Ajiu brought the assembly parts to P203 on the third day, just in time for supper.

Looking at Ajiu sitting on the table and having fun, Zheng Yi was quite happy and said, "We will go to Rongcheng together tomorrow."

"Um (no) um (ask) um (question)." said Ajiu.

Du Bin left the dining table silently.

He is going to work overtime tonight.

Du Ruo was not moved. Her specialty was planning and design, and her brother did the specific work.

The grandparents and grandchildren of the Ban family were also very happy and were hilarious and eating rare delicacies.

Well, it seems that after I picked up this doctor, I often have "rare" delicacies to enjoy.

"Teacher, do you know how to drive a truck?" Zheng Yi asked.

"That's much simpler than a sand truck." Old Banzhang said.

Zheng Yi could also get the shelter equipped with a official car, so there was no need to save them.

Even if you don’t use it yourself, you can still let the old team run for transportation.

"I will charge you a 1% management fee." Zheng Yi said.

The old man Zhang was ecstatic and hugged his grandson and laughed loudly, almost bursting into tears.

"Small class Jiade stayed to school," Du Ruo said coldly.

The old classmate was stunned for a moment and nodded repeatedly to thank him.

Xiao Banjia smiled awkwardly.

Zheng Yiru took Xiao Banjia's head: "Don't you like to do experiments very much?"

"Sister Ruo wants me to write an essay..." Xiao Banjia said weakly.

"What's the point of writing an essay? Your brother, I wrote a novel that was trembling and trembling," Zheng Yi laughed.

Xiao Banjia didn't believe it, and Du Ruo didn't believe it either.

Ajiu was still having a feast for nothing, and this business trip was so good.

After the five people finished their meal, Du Ruo packed the table, Ajiu went to find others to play cards, and Lao Banzhang took Xiao Banjia back to the sand bike to rest.

Zheng Yi was still energetic. Looking at Du Ruo who was busy cleaning up, he suddenly felt a move in his heart and casually brushed the [Sacred Healing].

Du Ruo looked at Zheng Yi calmly and asked without any ups and downs: "What's wrong?"

Zheng Yi smiled: "Before, due to surgical conditions, I didn't dare to scan you too much lymph...but now it's okay."

Du Ruo seemed to have nothing to do with him, and said softly, "Do you want to make up for your medical expenses?"

"Uh, no need." Zheng Yi saw that he couldn't continue chatting, so he went out for a walk obediently.

P203 rose in a short period of time and became a small market.

Most of the people who come here are truck drivers and the service staff they bring.

Zheng Yi wandered around outside and finally entered the bar.

After ordering a small amount of third-level water and a large amount of chemical waste liquid, Zheng Yi sat down at the bar, his ears were filled with the girl's flirting and the whistling of the truck driver.

Amid the roar of heavy metal music, a fairly fair arm hooked Zheng Yi.

"Doctor!" There was joy in his voice.

Zheng Yi turned his head and said, "So it's you, Asha."

Asha was stunned instead.

With the talent of a Sequence 7 scout, she recognized the "doctor" who escaped from death from her back, but this face...is a bit like another bastard doctor Asha who numbed herself.

As a wasteland young woman who can survive over twenty years old, Asha finally reacted: "You are the bastard who makes me mischief! No wonder you have been wrapping your head before!"

She wanted to tighten her arms, but finally failed.

The doctor was wearing stainless steel plate armor.

Relying on his upgraded body and hardened combat skills, Zheng Yi grabbed the scout's waist with his hands and picked her up and placed it on the high stool next to him.

The scout showed his tiger teeth, probably thinking that he would look more fierce.

It looks pretty cute.

Zheng Yi smiled and flipped his hand to take out a bottle of spring water from Renimo: "Please."

The scout pouted, took the bottle and shook his head, unscrewed the bottle cap with confusion, and sniffed it deeply.

"Extra-grade water?"

Asha suppressed her voice and her eyes widened.

Zheng Yi drank a lot of water at night and was not thirsty at all, so he ordered a glass of orange juice to put it on.
