"You're a buyer?"

"You're a seller?"

The woman was wearing a black suit on her upper body, a short skirt on her lower body, and a pair of sneakers on her feet.

The two questioned each other, and after confirming their identities, Chen Feng moved the battery off the electric car.

"The thing is here, are you inspecting it now, or?"

"You said that this thing can be used for a 3P air conditioner to run for 24 hours, I must verify it, 80,000 yuan is not a small amount, you have to at least come with me, right?"

Chen Feng was a little anxious because he didn't buy the production materials, and he was a little impatient when she asked him like this.

"Since I sold this thing, I definitely won't lie to you, if you don't believe it, this is my ID card, you take a photo, if it's fake, you call the police to arrest me." After speaking, Chen Feng took out his ID card and lowered it.

The woman took a photo with her mobile phone before she left with the battery satisfied, and the woman had just walked for less than five minutes when there was a prompt sound on the phone that the payment had arrived.

The selling platform is bound to a bank account, and the buyer will stay on the selling platform for a period of time after paying the money, and then the buyer will click to confirm the receipt of the goods, and the money will be automatically credited to the seller's account.

After sending things home, Chen Feng began to find materials on the Internet again, and he was busy all afternoon, but there was still nothing.

It wasn't until about eleven o'clock in the evening that Chen Feng finally gave up and leaned on the stool in a daze.

I didn't expect that I had just made such a fortune technology, and it was scrapped after only earning 70,000 yuan, and the platform took a part of his commission, so Chen Feng's real one-handed money was more than 70,000 yuan.

I was depressed for a while, and the time came to eleven fifty-nine, just when the number on the computer screen jumped to 00:00, suddenly a prompt sound popped up in Chen Feng's head.

"Today's Redeemable Technology Update"

"Dailies refreshed"

"Whew~ It's finally here!"

He had been looking forward to this moment when he didn't find the materials in the morning, and the search for materials in the afternoon was just to kill time.

Chen Feng couldn't wait to pull out the system panel and click on the Stardust Technology Mall, which was refreshed with three redeemable options.

The first one was just looking at the exchange price, and Chen Feng gave up.

Controlled Nuclear Fusion Boiler Material Synthesis Technology (with Basic Crafting Materials), Price: 100,000 credits

Human cryonics blending technology, price: 30,000 credits

Synthesis technology of neutralizer for harmful gases to humans, price: 2000 credits

The first two Chen Feng don't have to think about it, then he can only think about the last one, and this thing seems to be the most practical.

It just so happened that yesterday's newbie gift package gave away 2,000, and Chen Feng exchanged it for the synthesis technology of harmful gas neutralizers without thinking about it.

It's just strange that neither the refrigerant nor the neutralizer comes with basic materials, and yesterday's solar energy storage battery and controllable nuclear fusion boiler material synthesis technology all come with basic materials.

Does this mean that the materials of the first two are not easy to obtain, while the materials of the latter two are relatively easy to obtain?

It was easy to verify this statement, Chen Feng immediately opened the technology mall, took out the neutralizing agent, and spent five minutes learning this technique.

Sure enough, the synthetic materials for neutralizers are very readily available and can be bought in supermarkets.

It seems that the previous conjecture was correct, and the intimate system would provide the basic crafting materials for technologies that cannot collect materials.

The technique is in hand, but the points are empty, Chen Feng pouted and clicked on the daily task.

"Daily Mission: Random, Anywhere, Plant Five Trees (Reward: 10,000 Points)"

“？？？”

Chen Feng looked at the task question for five minutes, and finally he began to wonder if the tree word was a tree word.

"Planting five trees at random? Big or small? ”

The main thing is that it's already one o'clock in the morning, where to find the tree species?

Just when Chen Feng was at a loss, suddenly a bonsai reflection on the balcony attracted him.

Although it is a potted plant, it is a tree, this pine tree was replaced by Chen Feng with an air conditioner, of course, it is Feili Skin, the air conditioner of the beautiful heart.

Now there are four trees, and one is still missing...... Suddenly, Chen Feng had an idea, and there seemed to be a fortune tree in the doorman's uncle...... As......

In order not to cause unnecessary trouble, Chen Feng took advantage of the security guard sleeping and unknowingly pulled out the fortune tree in the flower pot, without considering whether it cut off the security guard's road to fortune.

After Chen Feng dropped two hundred yuan and walked away, after leaving the community, Chen Feng went directly into the community park.

Just next door to the community, this park also has a lot of activities for the elderly on weekdays, but there is no one at night...

After casually finding a flower bed and planting a tree, Chen Feng opened the system, and sure enough, the daily task showed that it had been completed.

The points have also arrived, but this point is still not enough to exchange for the other two technologies.

After that, Chen Feng bought the synthetic materials of the neutralizer at the 24-hour convenience store at the entrance of the community and returned home.

At this time, it was already two o'clock in the morning, Chen Feng was not sleepy at all, and his mind was full of scenes of neutralizers selling well.

If this thing is made, find a manufacturer to cooperate and get a package, which should be more profitable than light energy saving batteries.

The main materials are ethanol, deionized water, menthol, and the other three common materials are purified, and the neutralizer is formed after different proportions, which can be thrown with a humidifier.

Chen Feng has distillation and purification equipment at home, as well as centrifuges, of course, the latter is second-hand, which shows that Chen Feng sells a wide range of second-hand goods.

After returning home, Chen Feng immediately started to work, he didn't buy a lot of materials, only made three copies, because of the lack of some tools, the proportion of these three bottles is a little uneven.

Therefore, Chen Feng plans to find a suitable testing agency tomorrow to test its neutralizing effect on nicotine, formaldehyde, and some common harmful substances to people.

……

Early the next morning, Chen Feng was woken up by a phone call, it was the female buyer who called, and Chen Feng sat up from the bed with a cleverness.

At first, he thought it was something wrong with the battery, but the other party didn't seem to be because of this.

The other party asked him to meet, and his tone was not as cold as before, a mouthful of Mr. Chen, and this time the appointment was not a subway station, but a famous restaurant in Guangming District.

Chen Feng didn't refuse, just said that he was busy and went to the evening, hung up the phone and got up.
