After the system entered, Tang Xiao held his breath tightly. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The most unbearable thing for a winner is not knowing how many prizes he has won.

The system interface is very simple, with a vertical row of buttons on the side, and there are currently only four buttons, which are "Information", "Technology Tree", "Exchange", "Recharge", and "Smart Assistant". The first thing that catches your eye is the information about the characters.

Owner: Tang Xiao

Creature Class: Not enabled.

Enabled condition: Not triggered.

Tech Tree Level: Not enabled.

Upgrade Progress: Not enabled.

The information is simple to death, but what exactly does it mean Tang Xiao was confused, looking at the interface information in front of him, Tang Xiao frowned, "I don't understand, let's take a look at something else." ”

Calm down, Tang Xiao's mind moved, and he chose the technology tree, but now he was even more confused, and he clicked to go completely blank, and there was nothing.

"Holy! Nothing, the tech tree is just blank! ”

Secretly scolding, Tang Xiao hurriedly entered the "exchange" interface. This time, there was a big tab, "List of First-Class Civilization Technologies", and a large area of things that could be exchanged was densely packed under the tab. Seeing this, Tang Xiao finally breathed a sigh of relief.

"Whew-"

If it's still like the first two panels, there is nothing affordable, then it will really be disgusting. The saddest thing in the world is to pick up a wallet and find that the wallet is worth more than the contents of it.

After adjusting his mentality slightly, Tang Xiao immediately looked at it with his heart.

"Primary School Mathematics" - 1 energy point

"Primary School Chinese" - 1 energy point

"Elementary School Nature" - 1 power point

……

"Elementary Physics" - 2 energy points

"Elementary Chemistry" - 2 energy points

"Elementary Philosophy" - 2 power points

"I finally saw something valuable, but what exactly does this exchange mean. What are the power points? Tang Xiao thought habitually, but the light screen changed at the same time.

Under Tang Xiao's surprised expression, several rows of text appeared in the air like footnotes.

The handwriting appeared on the screen again, Tang Xiao was already surprised, and even more fortunately, if there was no such help, the system would probably not be able to figure it out for a long time.

"It's like if I just ask a specific question, and the system can read my thoughts and answer." Tang Xiao summed up secretly.

"Redemption means that by spending energy points, you can immediately and directly instill knowledge into your brain to achieve a state of integration."

"Well, that's not the same as a package of learning." Tang Xiao exclaimed, and his breath was suffocated.

"Yes."

Affirmatively, the moment Tang Xiao saw it, he seemed to be soaking in a hot spring when he was extremely tired, and the whole person who was comfortable was fluttering, and his eyes burst out with an amazing look, and his breathing was as rapid as a panting calf.

Of course, it's not because of the indoctrination of knowledge such as "Primary School Chinese" and "Primary School Mathematics", even if you don't indoctrinate it, it's not difficult, and you can say it yourself. The key is that Tang Xiao kept operating the scroll bar just now to turn the pages of the exchangeable products, and the things that can be exchanged in the back are the real attraction.

"Essentials of Electromagnetic Weapon Manufacturing"

"Detailed Explanation of Land-based Electromagnetic Gun Manufacturing"

Planetary Railgun Construction Technology

Theoretical Foundations of Antigravity

"Outline of Spaceship Construction in the Planetary System"

……

Countless technological products that are only in fantasy are displayed in front of you like commodities, and as long as there are enough energy points, you can exchange them.

Tang Xiao, who was originally worried about the arrival of the end of the world in five years, was swept away at this time.

"With these things, even if there will be an end times, there is absolutely nothing to fear!"

"By the way, the most critical thing is the energy point." Tang Xiao controlled his emotions and directly grasped the key point, the core of the exchange function that can be used is the energy point.

"What are the power points?" Tang Xiao asked tentatively.

"Energy points are the currency of the system, as long as there are energy points to save it, it can be exchanged for everything in the system."

"So how do you get power points?" Tang Xiao asked this question and stared at the screen tightly, "I hope the conditions are not too harsh." ”

Just as Tang Xiao was talking, the system had already given the answer.

"The energy point is recharged by absorbing external energy, and the charging method that the current system can support is electric energy. The specific method is as long as the host sets the parameters on the "recharge" interface and directly connects to the power supply with the body. ”

Seeing this, Tang Xiao couldn't wait to enter the "recharge" interface, the interface is simple and generous, and now there is only a lonely power recharge tool application icon on it, and as soon as the idea is selected, a setting option immediately pops up.

Recharge exchange rate: 100 kWh is equal to 1 energy point.

"100 kilowatt-hours of electricity to exchange for 1 energy point?"

"I remember that in 2026, the earth's resources will be further tightened, the progress of the earth's new energy will still not make much progress, and the electricity bill will continue to rise, and it will cost 2 Huaxia coins for one kilowatt-hour of electricity."

"Two yuan for one kilowatt-hour of electricity, then one energy point will cost 200 Huaxia coins!"

"Shhhh

Thinking of this, Tang Xiao hurriedly switched to the exchange page, and saw that it was now useful, not counting those leading technologies, but just those more cutting-edge technology exchange points, and couldn't help but gasp.

"The cheapest one starts at 10,000 points, that is, at least 2 million!"

"I'll go! Where did I get so much money! ”

"Host, don't worry, when the system is initialized, the host will be gifted the main technology of the first-level civilization technology tree. The host has not yet claimed it. Once claimed, the host will receive the main trunk of the Tech Tree that upgrades from a Level 1 civilization to a Level 2 civilization. ”

"Oh? Are you sure? Tang Xiao was overjoyed, "What is the trunk of the technology tree?" Is there still a tech tree branch? ”

"Intelligent assistants don't deceive people, the so-called backbone of the technology tree is the main technology nodes when the current civilization is upgraded from the current level civilization to a higher level civilization in the process of civilization upgrading, these technology nodes cannot be omitted, and the technology tree branch is not a necessary condition for civilization upgrading, it can be omitted."

"However, for example, if the exam has a full score of 100 points, and 60 points are considered to be passed, then only completing the main trunk of the tech tree is considered to be just passing, and the richer the branches of the tech tree, the higher the civilization score will be obtained at that stage, and correspondingly, the higher the potential for civilization to upgrade in the future. Otherwise, even if there is a super system, the development of civilization will be unsustainable or even interrupted. ”

"How so? The high-level ones will be all over, so the low-level ones should be easy, right? Tang Xiao exclaimed, "It is natural that it will be easy for advanced civilizations to learn things from low-level civilizations. ”

"The progress of civilization has a strong inertia, and there is really nothing wrong with comparing a limited number, and I even think that it will be easier to learn the advanced ones and then return to learn the lower ones. However, in essence, the inertia of civilization not only promotes civilization, but also promotes the cognition of civilized individuals, just as ants cannot understand elephants, elephants cannot truly understand the behavior patterns of ants. Zi is not a fish, how do you know the joy of fish? ”

"Zi Fei Fish, how do you know the joy of fish?" Tang Xiao was suddenly shocked, and suddenly brightened.

Not to mention the understanding of higher civilizations and lower civilizations, there are huge differences in the cultures of different races and ethnic groups among modern people. Tang Xiao sighed.

That's when a line of words appears on the screen.

"Do you want to receive the reward for the main trunk of the first-level civilization technology tree?"

Seeing this line of prompts, Tang Xiao was nervous and excited, and her fists clenched tightly.

No one knows the helplessness of seeing their loved ones engulfed in the apocalypse.

No one knows the fear and displacement when the real end strikes.

No one can appreciate the darkness of humanity in order to survive in the end times.

Jinling City is the last fortress in China, Tang Xiao, as an ordinary person, survived to the last moment in the apocalypse, not lacking courage, not lacking wisdom, but lacking the strength to contend with it!

Now, eight years ago, we finally have a source of strength to fight against the apocalypse, and we have the foundation to change the world. Tang Xiao clenched his fists fiercely and held his breath.

Resolutely silently said: "Receive!" ”

Whew――

At the same time, time seems to be frozen, and the whole body instantly loses consciousness, this moment is very weird, obviously conscious, but can not think, obviously can feel the body, but can not trigger action.

It seemed like a long time, but only a split second, and everything was back to normal.

"Reward Claim Successful!"

Tang Xiao had no intention of observing this line of prompts, and suddenly countless knowledge appeared in his mind, which looked very unfamiliar, but he was extremely proficient.

"Number Theory of First-Class Civilizations", "Computer Technology of First-level Civilizations", "Detailed Explanations of Quantum Computer Manufacturing", ,...... "Research and Development of Supermaterials for First-level Civilizations", "Linguistics of First-level Civilizations", ...... "Philosophical Systems of First-level Civilizations", ......"

The mind is like an ocean of knowledge, and the mind is like the speed of light to browse through all the catalogs in an unhindered instant, and every time I read a catalog, the knowledge in it is as if I have integrated it myself, and I can use it when I take it out.

"It's all true." Tang Xiao's tone trembled, and he couldn't help pinching himself a few times, and his painful mouth trembled a little, "It's true." ”
