Black technology: a super empire spanning two worlds

Chapter 5 [Even breathing air is charged]

Before Xiao Yu decided to spend money to rent a house, his first purchase on Blue Star was a set of breathing masks. Without a set of breathing masks, he could not leave the trading market because the outdoor air on Blue Star was not directly breathable.

In fact, Xiao Yu had long noticed that this trading market was a fully enclosed single building, isolated from the outdoors.

Moreover, almost every passerby in the trading market had a breathing mask and air bag hanging around his waist. Xiao Yu also saw through the transparent isolation wall of the trading market that passersby walking outside were all wearing breathing masks.

Why is this happening? Xiao Yu still had a lot of questions in his mind, but he could only suppress them temporarily and wait until his affairs on Earth were settled before conducting a systematic exploration and understanding of the situation on Blue Star.

"Fortunately, it's in the trading market..." Xiao Yu wandered around for a while and found a store selling respirators.

Xiao Yu entered the store and chose a set of breathing masks. He read the instructions and quickly understood how to use it. He immediately said to the store owner, "Boss, I'll buy this set. Please fill up the oxygen tank for me."

"Okay, a breathing mask costs 88 star coins, and a full tank of oxygen costs 5 star coins, a total of 93 star coins." said the boss.

Xiao Yu took out a 100-yuan bill from his pocket and handed it to the boss, who gave Xiao Yu 7 star dollars in change, then took the air bag to pressurize and inject oxygen.

After finishing the job, Xiao Yu left the store and found the exit of the trading market. Many people who were going out put on breathing masks, and Xiao Yu himself also put on the breathing mask he had just bought.

In front of you is a curved structure made of transparent material, and outsiders can see your facial features clearly even when you put on a breathing mask.

"It's actually a smart screen?" Xiao Yu was secretly surprised when he saw some data information displayed in front of him. The display material was obviously more advanced than that on Earth. At such a close distance from the breathing mask, it seemed like a front-view eyepiece.

Xiao Yu immediately became interested in this material. One of the core businesses of Prism Technology, which he founded, is semiconductor display, that is, display screens, including mobile phone screens, computer screens, etc. Prism Technology is also a supplier to several mobile phone manufacturers, but of course it is not a major mobile phone manufacturer.

But at this moment, Xiao Yu followed other local natives into a passage cabin, and then the door on the other side opened, and he followed everyone out of the trading market and came outdoors.

The outdoor atmospheric composition data was quickly displayed in front of the mask. Xiao Yu couldn't help but mutter: "Nitrogen 76.88%, oxygen 16.87%, carbon dioxide 1.89%, argon 0.95... Hmm? No, did I misread the carbon dioxide concentration?"

At this moment, Xiao Yu's attention was quickly focused on the carbon dioxide content, and he confirmed again that he was not mistaken, the content was 1.89%.

"Why is the carbon dioxide content in the atmosphere of Blue Planet so exaggerated?" Xiao Yu was surprised. He remembered that the carbon dioxide red line broken by his hometown Earth in 2019 was only 0.041%. The carbon dioxide content in the atmosphere of Blue Planet is actually 46 times that of Earth.

"No wonder we have to wear a breathing mask." Xiao Yu suddenly realized. You know, 0.2% carbon dioxide content in the atmosphere is enough to make sensitive people breathe poorly. If it is increased five times, even people with strong physiques will suffer from carbon dioxide poisoning.

The carbon dioxide concentration in the atmosphere of the Blue Planet is so high that humans can only sustain it for about 10 to 15 minutes at most. If they do not leave such an environment in time, they will face the risk of shock or even death.

"In this world, even breathing air costs money..." Xiao Yu shook his head with a smile.

About half an hour later, Xiao Yu found a house in this town and successfully rented it. Originally, identity registration was required, but Xiao Yu used Star Yuan to settle the matter with the landlord.

Money can also be used to open the way in the Blue Star world. The house that Xiao Yu rented was fully equipped and ready for immediate move-in. He then went out again and returned to the trading market to buy a lot of products and materials, and then returned to the newly rented house with a full bag.

“Pick out any one of these products and it will cause a huge sensation on Earth.” Xiao Yu placed all the things he bought on the table and felt excited looking at these products.

After a while, Xiao Yu picked up one of the exquisite boxes and took out the products inside.

It is a smart holographic bracelet, a wearable smart communication device. Its functions and positioning are the same as those of smart phones on Earth. But it is no surprise that the holographic bracelet is definitely a black technology product that is decades or even hundreds of years ahead on Earth.

"Incredible, so many precision components are integrated into a ring structure the size of a bracelet..." Xiao Yu was shocked when he looked at the holographic bracelet product in his hand. He was engaged in technical research and development, so he was even more shocked. How high is the integration of the chip? And how to dissipate heat? How high is the energy density of the battery? Many technical questions quickly popped up in Xiao Yu's mind.

The holographic smart bracelet in Xiao Yu's hand is in "Mist Silver" style. He went to a local store and spent 399 star dollars to buy the flagship version, while the standard version is 299 star dollars.

At this moment, Xiao Yu compared the holographic smart bracelet he had just bought with the teleportation star ring on his left wrist.

The size of the two are actually similar, but the difference is that the surface of the teleportation star ring is extremely smooth, it is extremely smooth, and at just one glance, the intuitive feeling given is that the teleportation star ring is more advanced.

Until now, Xiao Yu still didn't know the origin of the teleportation star ring. When he woke up, he found that he was wearing this star ring inexplicably on his hand, and he couldn't take it off at all.

Xiao Yu estimated that this star ring might be the product of some advanced civilization and was definitely not formed naturally. Its powerful ability had already exceeded Xiao Yu's cognition, and he could only regard it as a product created by some great god-level civilization.

Although the technology of the Blue Star world is far superior to that of the Earth, it is basically within Xiao Yu's cognitive scope and is under the same framework of physical laws. However, this teleportation star ring has obviously surpassed Xiao Yu's understanding of science and technology.

Looking at the holographic bracelet I just bought again, there is a structure similar to a camera hole with a diameter of 3.5 mm on the outer ring surface, and the holographic image is projected outward from this position.

Xiao Yu already knows how to operate it, and the learning cost is very low. Basically, as long as you can use a smartphone, you can easily play with the holographic bracelet. The difference is that the interaction method is different. The smartphone interacts by touching the physical screen, while the holographic bracelet interacts by touching the virtual panel.

At this time, a two-dimensional holographic panel formed a two-dimensional holographic display panel above the structure similar to the camera hole.

Xiao Yu tried it and found that the size of the panel can be enlarged or reduced at will. He only needs to touch the holographic screen with his hand, and then he can enlarge or reduce the size of the holographic panel just like he zooms in and out a picture on a smartphone.

At this moment, Xiao Yu enlarged the holographic panel to about 12 inches. He slid it on the two-dimensional desktop and clicked on some applications.

"Wow, there's a 3D desktop mode?" Xiao Yu was slightly surprised. After switching to the 3D desktop mode, all the applications became three-dimensional. Xiao Yu couldn't help but murmur as he tried it: "If this product is released on Earth, it will compete with smartphones and will definitely easily kill all smartphone brands..."
