The film light curtain dissipated, and Li was in good condition. He slowly looked at the room and accidentally discovered that there was actually a material storage tank here.

"Hey, isn't this a coincidence?"

Li Zheng took out his old friend casually, showed a familiar smile, and walked over.

"It seems that not everyone knows that various equipment can be broken down after being destroyed. Xiao Siyuan didn't smash it when he left this room."

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

"It's similar to what I imagined. After the player leaves a certain room, he just cannot look back, which does not mean that others cannot enter from that direction."

Li Zheng remembered that every room he passed by was destroyed in a mess, and suddenly thought with some bad taste, "If someone entered the room I had explored and found it was messy and there was nothing to use, I wonder what they would think?"

Dong, Dong, Dong!

After the ribs were cured, Li Zheng had no worries and let go of his hands and feet. In a short while, he smashed the material storage tank to a decomposition level.

"break down!"

【Decompose the damaged material storage tank, obtain: temperature controller *1, damaged power core type 3*1,…】

"Um?"

Li Zheng frowned. He avoided the upper left half when he was demolished and smashed, but he still broke the power core. "So, is the power core installed on the right?"

Taking this in mind, Li Zheng looked at the three doors that could enter, and once they opened and two gates were closed.

The one that was open was the route Xiao Siyuan entered here, and the two closed were green material security doors.

"Xiao Siyuan's luck... is so bad. He just chose the remaining one-third of the safety rate?"

Li Zheng chose a mobile phone and swiped the card to enter.

In the next two rooms, Li Zheng entered and searched, and smashed them after searching. He would never miss any of the things he could take away.

...

"I finally got all my exploration share today. Let's take a break and have supper."

"Yeah!"

Sakura poked her head out of the pocket and rubbed her hands expectantly.

"You little foodie."

Li Zheng pointed Sakura's head funny, causing the little guy to protest.

"Yeah!"

Sakura flew out and raised her hands high to indicate that she was not a foodie.

"Okay, our Sakura is either a foodie, but she just likes to taste delicious food." Li Zheng said perfunctorily.

"Yeah, hum!"

Sakura always felt that this was wrong, but she couldn't figure out what was wrong, so she had to snort and turn her head.

"Okay, you get out of the way and I'll let go of my residence."

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

Take out four ginseng flowers and eat them by yourself. After the salt-baked glands are thawed, take a part, heat it up and hand it to Sakura, "Here, this is yours."

After eating, replenish hydration.

"Tons of tons...ha~" This is Li Zheng.

"Ton of Guru, tons of tons... burp~" This is Sakura.

"Hahaha!"

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

Sakura blushed and protested, refusing to admit that her hiccups destroyed the image of "lady".

After using dinner, Li Zheng threw away the empty water bottle and collapsed on the small remaining fiber balls. Sakura was a routine, flying outside to have fun and eating.

"Oh~~~ah...comfortable!"

Suddenly relaxed, Li Zheng felt his whole body sore and had no desire to move.

"This time the detector should take a lot of time, so I will upgrade it first."

Remove the detector and open the system interface.

"upgrade!"

【Advanced scientific detector materials are sufficient, confirm the upgrade...

This upgrade will consume: AI core*1, titanium air alloy 300g, power core type 4*1, basic module*30]

[The expected time for this upgrade is: 8 hours.]

I turned around and roughly counted the supplies, and found that I had saved all day long, but now I still only have a bottle of pure water.

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

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

Before, temporary transactions were urgent, so the price was relatively cheaper.

At this time, some of the people who have traded before should have used the snake grass needle. After experiencing the benefits of the snake grass needle, these people will definitely be obsessed with 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 I would have shouted on the World Channel and sold it a little faster.

Now... I don't know when they will find my trading order."

"Put ten pieces first and replace them with two liters of water."

After finishing it, I looked at the time. It was almost dark and there was nothing left and right. Li Zheng suddenly remembered that he had a drawing.

[Air purifier, bronze grade, disposable

Description: An air purifier can be made.

Required materials: Parts*5, Iron ingot*5, Copper ingot*5, Power core type 2*1]

It is the air purifier drawing that was opened in the bronze treasure chest today.

"Need a Type 2 power core?"

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

The list has been refreshed, and all the power cores of the models currently on sale have appeared in front of him, and the number is very considerable.

"So many?" Li Zheng was slightly surprised, "I haven't gotten a few power cores in a day, and someone has taken it out to trade it out?!"

Li Zheng looked at the orders in the trading hall and screened out the core of motivation that he could afford one by one.

"Power Core Type 1, trade a liter of clean water? Is it so cheap?"

The first trading order surprised Li Zheng for a long time, and then he realized that he had explored twenty rooms in two days, along with the initial gifts, but he only saw three bottles of water.

It's only 1.5 liters in total.

After flipping down, Li Zheng found that there were quite a lot of players using the Type 1 Power Core to trade water resources.

Moreover, most of the trading requirements set are between one liter and one liter and one liter.

After reading it, he stroked his chin and looked thoughtful, "If you use a water purifier, a power core 1 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 1. Can I earn 500 milliliters to one liter of water inside and outside? What about this good thing?"

It's incredible, but after calculation, Li Zheng found that this is really a good thing!

The facts are all in front of you. No matter how incredible it is, it has happened, and Li Zheng has no choice but to believe it.

"This is obviously abnormal... If it's so easy to make money, didn't a sucker buy the water purifier that William resold? He didn't even notice this bug? Could it be that he died in the matrix, right?"

When Li Zheng thought of this, he 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 that sucker will go to see God during this period?

"But the matrix is ​​so big, 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 "purification of water". After converting the list, he found that most of them were actually black iron-level props called "purification of water effervescent tablets".

"Water effervescent tablets, consumables, put them in 100 ml of sewage for three hours and you can get ninety ml of purified water. The price is...good guy!" Li Zheng exclaimed: "You actually need 80 ml of clean water to sell it? I really want to call you the most raper!"

When Li Zheng looked at the seller's name again, he was speechless on the spot.

William Houston!

"How can you see the name of this B everywhere?"

Skipping the unpleasant name, Li Zheng looked at other water purification equipment, such as: sand and gravel water filters, distillation machines, water molecule extractors, etc.

However, these devices are set in rental mode, and no player sells them.

And there are more or less some shortcomings.

Like a sand and gravel water filter, while filtering water, it will also consume "sand and gravel" materials, and it is difficult to find sand and gravel alone.

After all, in the matrix, most rooms are science fiction-style metal rooms, and it is difficult for you to find some stones to break them out.
