The thin-film light curtain dissipated, and Li Zheng just took time to look at the room slowly, and unexpectedly found that there was actually a material storage tank here.

"Hey, isn't this a coincidence?"

Li Zheng took out his old friend and walked over with a familiar smile.

"It seems that the settings that can be decomposed after various devices are destroyed, not everyone knows that Xiao Siyuan didn't smash it when he left this room."

That's right, Li Zheng chose neither the red dangerous room nor the upper and lower doors, but the room where Xiao Siyuan came from.

"It's similar to what I imagined. After the player leaves a certain room, it's just that he can't turn back. It doesn't mean that other people can't enter from that direction."

Li Zheng remembered that every room he passed by was destroyed in a mess, and suddenly thought with some wickedness, "If someone enters the room I have explored and finds a mess, there is nothing that can be used, I don't know what they will do. think?"

Boom, boom, boom!

After the rib was healed, Li Zheng had no worries, let go of his hands and feet, and after a while, he smashed the material storage tank to the point where it could be decomposed.

"break down!"

[Disassemble the damaged material storage tank to obtain: Temperature Controller*1, Damaged Power Core Type III*1, …]

"Um?"

Li Zheng frowned. He avoided the upper left half when he demolished it just now, but he still demolished the power core. "So, the power core is installed on the right side?"

Keeping this in mind, Li Zheng looked at the three doors that could be entered, one opened and two closed.

The open door is the route Xiao Siyuan took to enter here, and the two closed doors are green material security doors.

"Xiao Siyuan's luck... He's so lucky that he has a bad mid-band, two-thirds of the safety rate, but the remaining one-third?"

Li Zheng chose a fan and swiped his card to enter.

In the next two rooms, Li Zheng entered and searched, and smashed it after searching, but he would never let one of the things that he could take away.

"Finally got all the exploration shares for today, rest for a while and have dinner."

"Hey!"

Sakura stuck her head out of her pocket and rubbed her little hands expectantly.

"You little foodie."

Li Zheng smiled and nodded Sakura's head, causing the little guy to protest.

"Hey!"

Sakura flew out and raised her hands high, indicating that she was not a foodie.

"Okay, okay, our Xiaoying is not a foodie, but just likes to taste delicious food." Li Zheng said a few words perfunctorily.

"Hey, huh!"

Sakura always felt that this was not right, but she couldn't figure out what was wrong, so she snorted and turned her head away.

"Okay, get out of the way, I'll release the residence."

Li Zheng threw the capsule out, and after the house was enlarged, he opened the door and took Sakura in.

He took out four ginseng flowers and ate them by himself. After the salt-roasted glands were thawed, he took part of it and heated it up and handed it to Sakura, "Here, this is yours."

After eating, add water.

"Tontonton...ha~" This is Li Zheng.

"Ton gulu ton ton...hic~" This is Sakura.

"Hahaha!"

Li Zheng pointed at Sakura and laughed, this guy learned from himself again, and then hiccupped.

Sakura blushed in protest, refusing to admit that her hiccups had ruined her "lady" image.

After dinner, Li Zheng threw away the empty water bottle and slumped on the little fiber mass left, while Sakura flew outside to have fun and digest her food as usual.

"Hey~~~ ah...comfortable!"

Suddenly relaxed, Li Zheng only felt sore and weak, and he had no desire to move at all.

"This time the detector should take a lot of time, let's upgrade it first."

Remove the detector and open the system interface.

"upgrade!"

[The materials for advanced scientific detectors are sufficient, confirm the upgrade...

This upgrade will consume: AI Core*1, Titanium Air Alloy 300g, Power Core Type IV*1, Basic Module*30]

[The estimated time required for this upgrade is: 8 hours. 】

He turned his head to roughly count the supplies, and found that he had spent the whole day and saved again and again, and now there is still only one bottle of pure water.

"There's not much water, let's trade some more."

Li Zheng opened the trading floor, put a snake grass needle, and exchanged one snake grass needle for two hundred milliliters of pure water.

Previously, temporary transactions were more urgent, so the price was relatively much cheaper.

At this time, some of the people who have traded before should have already used the snake grass needle. After realizing the benefits of the snake grass needle, these people will definitely not forget it. Even if they find that the price has doubled, some people will buy it.

"It's a pity that there is no small speaker, otherwise, if you shout on the World Channel, it will definitely sell faster.

Now... don't know when they'll find out about my trade list. "

"Put ten sticks on it first, and change two liters of water."

After he was done, he looked at the time. It was about to enter the dark night, and there was nothing to do. Li Zheng suddenly remembered that he still had a drawing.

[Air Purifier, Bronze Grade, Disposable

Description: Can make an air purifier.

Required Materials: Parts*5, Iron Ingots*5, Copper Ingots*5, Power Core Type II*1]

It was the blueprint of the air purifier that was opened in the bronze treasure chest today.

"Need a Type II power core?"

Li Zheng rubbed his brows in distress, opened the trading floor, and searched for the power core.

The list is refreshed, and all the models of power cores currently listed for sale appear in front of him, and the number is very considerable.

"So much?" Li Zheng was slightly surprised, "I didn't get a few power cores in one day, and there are people who have extra to trade?!"

Li Zheng looked at the list on the trading floor and screened the power cores that he could afford one by one.

"Power Core Type I, trading a liter of clean water? Is it so cheap?"

The first transaction list surprised Li Zheng for a long time. After that, he realized that he had explored twenty rooms in two days, even with the initial gifts, but only saw three bottles of water.

Only 1.5 liters in total.

Scrolling down, Li Zheng found that there were quite a few players who traded water resources with Type I power cores.

And most of the set transaction requirements are between one liter and one and a half liters.

After reading it, he rubbed his chin with a thoughtful look in his eyes, "If you use a water purifier, one Power Core Type I can convert up to two liters of sewage, and the conversion ratio is close to 100%.

Then use the purified water to trade the power core of Type I, can I earn 500ml to one liter of water inside and outside? And what about this good thing? "

It's incredible, but after calculating, Li Zheng found out that there really is such a good thing!

The facts are in front of us. No matter how incredible it is, it has happened. Li Zheng can't help but believe it.

"This is obviously not normal... If it's so profitable, didn't someone buy the water purifier that William re-sold before? He didn't find this bug? Shouldn't he have died in the matrix?"

Thinking of this, Li Zheng suddenly sat up and was shocked, "It's not impossible!"

In the matrix, I don’t know how many players will die every hour. Maybe the bad guy went to see God during this period?

"But with such a large matrix, it's impossible for me to get the drawings of the water purification equipment alone, right?"

Li Zheng turned his head and searched for the word "purifying water" again. After changing the list, he found that most of them were actually black iron-grade props called "purifying water effervescent tablets".

"Water purification effervescent tablets, consumables, put it in 100 ml of sewage and let it stand for three hours to get 90 ml of purified water. The price is... good guy!" Li Zheng exclaimed: "It takes 80 ml to clean it. Only willing to sell the water? I would like to call you the most rapist!"

Looking at the seller's name again, Li Zheng was speechless on the spot.

William Houston!

"How come you can see this B's name everywhere?"

Skipping off the unpleasant names, Li Zheng took a look at other water purification equipment, such as: sand and gravel water filters, distillation machines, water molecule extractors and the like.

However, these devices are all set to rental mode, and none of the players have taken them out for sale.

And there are more or less some disadvantages.

Like a sand and gravel water filter, while filtering water, it also consumes "sand and gravel" materials, and it is difficult to find just this sand and gravel.

After all, in the Matrix, most of the rooms are sci-fi metal rooms, and it is difficult to find some rocks to break them.

Moreover, not to mention the long water filtration cycle, the 100% conversion of the water purifier cannot be achieved.

Or like a distillation machine, although it is the same as a water purifier, it only needs to consume the power core, but the energy consumption is slightly lower than that of the water purifier, and the conversion ratio is very low and the time is long.

The water molecule extractor does not consume much, but the water purification cycle is long. It takes ten hours to extract one liter of water, and the efficiency is extremely low.

In comparison, the price/performance ratio of the water purifier is the highest among all water purification props.

Although the energy consumption is the largest, the conversion rate is high and the speed is fast!

"I feel like I can make a lot of money tonight!"

Li Zheng was completely excited and began to search for sewage.

"One hundred and fifty milliliters of sewage, traded for one hundred milliliters of clean water? I bought it!"

"Two hundred milliliters of sewage, UU reading www.uukanshu.com to trade an item to develop genetic abilities? Get out!"

"Twenty milliliters of sewage, trading any matrix biological blood? Want to eat shit?"

"Fifty milliliters of sewage, trading the flesh of any matrix creature? My urine is yellow, and if you don't wake up, you will be ashamed!"

Picking and choosing, Li Zheng replaced the 500ml of clean water in his hand with 800ml of sewage.

"There's not enough water."

When he opened the regional chat channel, Li Zheng didn't care what was being chatted inside, and sent a message directly.

Li Zheng: [Snake grass needle] Change the power core type I, the price is private if you are interested.

Fengshan: @李正, shouldn't the price be clearly marked?

Lu Li: 9494.

Li Zheng: @Lu Li, dear son, what are you talking about?

Lu Li: Ahem, I mean nine snake grass needles for four power cores.

Li Zheng: @Lu Li, change! I can't take it out and kill you!

Lu Li: Dad, I was wrong!

Fengshan: @Lu Li, I'm your uncle, call me first before being beaten to death!

Li Chun: Then am I not an aunt?

Yanguang: Blind student, did you discover Huadian?

Li Zheng: Change ten snake grass needles for one power core, only one, speed, first come first served!

Passerby: I'll change it!

Li Zheng: Okay, it's up to you, the trading floor will name you.

Fengshan: ? ? ?

Land from:? ? ?

Passerby: [Snake Grass Needle] @李正, thank you big guy! @Fengshan, thank you for bargaining! Mua!

Fengshan: Get out! !

Lu Li: Does this count as snipe and clam fighting for the fisherman's profit?

Fengshan: You also get out of here!

Lu Li: Good!
