A Business Opportunity

The light film disappeared, and Li Zheng looked around the room slowly. He was surprised to find that there was a material storage tank.

"Hey, this again!"

Li Zheng took out his beloved tool and walked over with a smile.

"It seems like not everyone knows that all the equipment can be disassembled. Xiao Siyuan didn't destroy it when he left the room."

That's right, Li Zheng didn't choose the red dangerous room, nor did he choose the top and bottom doors. Instead, he chose the room Xiao Siyuan came from.

"Just as I imagined, after a player leaves a room, they can't turn back, but it doesn't mean that others can't enter."

"What would people think if they entered the rooms I explored and found nothing useful?" Li Zheng thought about how all the rooms he had passed by were destroyed.

Thump, thump, thump!

After his ribs were healed, Li Zheng no longer had any concerns. He went all out, and it didn't take long for him to break down the material storage tank.

"Disassembled!"

[You obtained: thermal controller x1, type III damaged power core x1...]

"What?"

Li Zheng frowned. He'd avoided the upper left part when he was dismantling the machine, but he'd still damaged the power core. "So, the power core was installed on the right side?"

Keeping this in mind, Li Zheng looked at the three other doors. One was open, and two were closed.

The one that was open was the route that Xiao Siyuan had taken when he entered this place, and the two closed doors were green safe rooms containing materials.

"Xiao Siyuan is quite unlucky, he chose the only dangerous room."

Li Zheng chose one and swiped his card to enter.

In the next two rooms, Li Zheng searched every corner and smashed everything he could. He didn't let anything go.

...

"Finally done with today's quota, let's rest and eat."

"Chirp!"

Chirpy poked its head about and rubbed its hands in anticipation.

"What a glutton!"

Li Zheng patted Chirpy's head which it tried to resist.

"Chirp, chirp, chirp!"

Chirpy flew out and raised its hands high, protesting.

"Alright, alright," Li Zheng said casually.

"Chirp, hmph!"

Chirpy was not satisfied with his reply.

"Alright, move aside. Let me place the capsule."

Li Zheng placed the capsule and went in with Chirpy.

He took out four ginseng flowers and ate them himself. After the glands were thawed, he took out a portion and heated it up before handing it to Chirpy. "Here, this is yours."

After eating, he drank some water.

"Ahh..." This was Li Zheng.

"....burp~" This was Sakura.

"Hahaha!"

Li Zheng pointed at Chirpy and laughed out loud. It copied him again, and burped.

Chirpy's face reddened as it protested, refusing to admit that its burping had destroyed its image as a "lady".

After dinner, Li Zheng threw away the empty bottle and lied on top of the remaining fiber. As usual, Chirpy flew around to digest the food in its stomach.

"Ah…this feels so good!"

Li Zheng's entire body felt sore and limp, and he had no desire to move at all.

"It doesn't take long for the detector to upgrade, let me do it now."

Taking off the detector, he opened the system interface.

"Upgrade!"

[Sufficient materials, confirming upgrade…]

[Materials used: AI core x1, titanium alloy 300g, type IV power core x1, basic module x30.]

[Estimated time to completion: 8 hours.]

He turned around and did a rough check on his supplies. He realized that even though he had been saving it, he only had a bottle of water left.

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

Li Zheng opened the trading room and listed the snake grass needles. One snake grass needle was exchanged for 200 milliliters of water.

Previously, the transaction had been more urgent, so the price was relatively cheaper.

At this time, some of the people who had previously traded with him should have already used up the snake grass needles. After knowing the benefits of the snake grass needles, these people would definitely be obsessed with them. Even if they found out that the price had doubled, there would still be people who would buy it.

"It's a pity I don't have a loudspeaker. Otherwise, I could have announced it on the world channel and sold it faster."

"Now ... I don't know when they'll find out about my offer. "

"Let me list 10 pieces for 2 liters of water."

When he's done, he looked at the time and realized that it's already night time. Suddenly, he remembered the blueprint.

[Air purifier. Bronze-grade. One-time use.]

[Description: can be used to craft an air purifier.]

[Materials required: spare parts x5, iron ingot x5, copper ingot x5, type II power core x1.]

It was the blueprint for an air purifier he received from today's treasure chest.

"I need a type II power core?"

Li Zheng frowned and opened the trading room to search for power cores.

There were a lot of offers.

"So many of them?" Li Zheng was curious, "I didn't get that many power cores from today's explorations, but there are so many people offering them?"

Li Zheng looked at the listings and looked through them.

"Type 1 power core for a liter of clean water? So cheap?"

The first listing surprised Li Zheng. Then he realized that he only found 3 bottles of water after exploring 20 rooms in 2 days.

There were only 1.5 liters in total.

As he scrolled down, Li Zheng realized that there were quite a number of players trading power cores for water.

Moreover, most of the trading requirements were between 1 to 1.5 liters.

After reading it, he rubbed his chin and pondered. "A power core can be used to convert up to 2 liters of sewage into clean water, and the conversion rate is close to 100%."

"Then, trade the water for a type I power core, isn't that great?"

It was great indeed.

"But that doesn't make sense…if it's that good, why did someone sell the water purifier for cheap? Did he not discover the bug? Or is he dead?"

Li Zheng suddenly sat up, "it's not impossible!"

A lot of players died every hour, perhaps the person was dead.

Then, Li Zheng searched for "clean water" in the trading room and found many items with the title "bronze-grade water purification effervescent tablet".

"Water purification effervescent tablet, consumable. Place it into 100ml sewage for 3 hours to obtain 90ml of clean water. The price is…damn!" Li Zheng was stunned, "they are asking for 80ml of clean water? What a profiteer!"

Li Zheng was speechless when he saw the seller's name.

William Houston!

"Why do I keep seeing this b*astard?"

Skipping the unpleasant name, Li Zheng looked at the other listings, such as "sand and gravel water filter", "distillation machine", "water molecule extractor'" and the like.

However, these equipment were all for rent, so none of the players were selling them.

Moreover, they all had some flaws.

For example, the sand and gravel water filter required sand, which was not easy to find.

In the matrix, most of the rooms were sci-fi style metal rooms. It was difficult to find some sand and stones.

Moreover, the filtering cycle was long, and it could not achieve 100% conversion like the water purifier.

Although the distillation machine only requires a power core like the water purifier, the energy consumption was slightly lower than the water purifier. Moreover, the conversion ratio was lower and the time was longer.

The water molecule extractor did not require much water, but it had a long cycle. It took ten hours to extract a liter of water. Its efficiency was ridiculously low.

In comparison, the price-performance ratio of the water purifier was the highest among all the devices.

Although the energy consumption was the highest, the conversion rate was high and the speed was fast!

"I think I'm going to make a fortune tonight!"

Li Zheng was excited as he began to search for sewage.

"150 ml of sewage for 100 ml of clean water? I'll take it!"

"200 ml of sewage for an item to develop special abilities? Get lost!"

"20 ml of sewage for the blood of any matrix creature? No way"

"50 ml of sewage for the meat of any matrix creature? Dream on!"

…

After some careful selection, Li Zheng exchanged the 500ml of clean water he had with 800ml of sewage.

"I don't have enough water."

Li Zheng opened the regional chat channel and sent a message.

[Li Zheng: "Exchanging snake grass needles with type I power cores. Those interested please let me know."]

[Feng Shan: "@Li Zheng, shouldn't you state the price?"]

[Lu Li: "9494."]

[Li Zheng: "@Lu Li Son, what are you saying?"]

[Lu Li: "Ahem, I mean, 4 power cores for 9 snake grass needles."]

[Li Zheng: @Lu Li Deal! I'll kill you if you're bluffing!]

[Li Li: "Sorry, dad."]

[Feng Shan: "@Lu Li, I am your uncle.]

[Li Chun: "Then I'm your aunt?"]

[Li Zheng: "10 grass needles for 1 power core. First come first serve."]

[Passerby: "I'll take it!"]

[Li Zheng: "Sure, see you at the trading room."]

[Feng Shan: "???"]

[Lu Li: "???"]

[Passerby: "@Li Zheng, thank you boss! @Fengshan, thank you for bargaining! Muah!"]

[Feng Shan: "Get lost!!!]

[Lu Li: "Is this the fisherman who benefits from the fight between the sandpiper and the clam?"]

[Feng Shan: "You get lost too!"]

[Lu Li: "Okay."]
