The difficulty has undoubtedly increased exponentially compared to before.

After the Blue Star people's technology developed into the artificial intelligence era, they took a wrong path, which led to internal disagreements.

But the fundamental reason is that it is really difficult to break through the original technological upper limit, which ultimately leads to conflicts.

As for the other energy-driven route, it seems that the upper limit is much higher than that of technological civilization.

According to the analogy of human research progress.

Even though the Blue Stars have developed nuclear fission and iterated it into several versions.

Research on the human body is still at its rudimentary extreme, and the secrets of evolution have not yet been mastered.

That's why the Kyushu Rift Valley Research Institute became so interested after discovering that Earth players could improve so easily.

However, the upper limit is the upper limit, and the difficulty is the difficulty.

Although the upper limit of technological civilization may not seem high for the time being, its advantage lies in stability.

As long as we copy the development of human beings on earth step by step, we can quickly achieve the same progress in the wasteland.

And this process should not be very difficult.

Although the upper limit of energy-chasing civilization is higher, the difficulty is visibly exaggerated.

Choosing this option means that you will definitely accept a severe challenge next.

At least those upgrade conditions will no longer be easy to complete. It will probably take a lot of effort. It may even be impossible to complete.

What to choose?

He hesitated for less than half a minute, staring at the majestic warning wall in front of him.

Soma paused for a moment and concentrated his thoughts.

It seems like a decision that doesn't require too much ambiguity.

Compared with the options that required double selection in the past, the advantages and disadvantages often overlap with each other, making it difficult to choose.

The advantages and disadvantages of this civilization upgrade choice are obvious, and the difficulty of making a decision is almost zero.

After all, I missed the energy-chasing civilization, and if I want to get in touch with this power beyond the scope of human cognition, I basically can't find any other suitable way.

If you miss the dark civilization, existing technology will not be affected.

At best, the development is just a little slower.

Even now, the technology of the territory has completely deviated from the previous research direction of mankind in some aspects. A series of new products derived from energy stones have overtaken the market, and the use experience has completely surpassed modern products.

Thinking about it this way, why is there any need to hesitate?

"System, I choose to upgrade"

"The Era of Chasing Energy."

[Record]: The direction of civilization upgrade has been selected.

[Record]: Civilization upgrade has officially begun. This wonder upgrade will be affected by your choice.

【Record】:5,4,3

Boom.

There was thunder on the ground, and the sound spread hundreds of thousands of miles.

As the countdown in the system panel ends.

In an instant, a pale golden lightning flashed across the sky like a long dragon and hit the warning wall heavily.

Under the stunned eyes of hundreds of guards, the originally thick black wall suddenly turned into a dazzling light gold.

It's like it's been covered with a layer of armor, and it's like it's completely changed the material structure on the surface.

Electric arcs continued to fly out of the wall, causing bursts of crackling sounds.

What's going on?

Seeing this scene, Sumo couldn't help but feel a little happy.

Sunny Harbor Shelter named its giant wall ‘Lightning Wall’, which means that even lightning cannot break through it.

But now, comparing the two parties, the warning wall in their own territory is more fitting for this name.

About four or five minutes passed before the current stopped slightly.

After absorbing that magical golden lightning, the wall originally made of ordinary materials has truly acquired capabilities that are beyond the scope of this technology, and the light golden color on the surface has completely disappeared into the interior.

As the second wonder of the territory, when all the dust has settled.

Just from the appearance, you can't tell much difference from the previous warning wall.

The only thing that has changed is probably that some of the mistakes originally made by the workers during the construction process have disappeared.

For example, the position of the bricks is deviated, or the amount of cement applied is too much.

Now that these mistakes have disappeared, the entire warning wall looks more rounded and natural, and even the potholes on the surface look unusually unique, like works of art.

[Record]: The wonders have been upgraded. Please enter the game panel to check the specific attributes after the civilization upgrade is completed.

[Record]: Civilization upgrade is in progress, current progress: 24.5%

[Record]: The estimated remaining upgrade time is six minutes and fifteen seconds.

The main event is completed.

The next upgrade seemed to be much gentler, and there was no such strange phenomenon that shocked the entire New World.

Glancing at the surprised looks of the surrounding guards, Sumo didn't bother to explain anything and was ready to blame it all on Yugi.
Chapter completed!
