Chapter 154

the amount consumed is 10 times that of the previous era.

For example, Lin Yi unlocked 2020 artillery, which consumed 200 million US dollars,

then by 2030, it would be 2 billion US dollars.

However, even if 2030 artillery became laser cannons,

Lin Yi felt it was still not worth 2 billion US dollars.

Of course, this fee is not static. If the era Lin Yi is in reaches 2020,

then unlocking would become a 2-fold multiplier again.

Spending a total of 705 million US dollars, Lin Yi unlocked all existing weapon catalogs to the latest era.

He then began to focus on the material technology tree, equipment technology tree, and biological technology tree.

Especially the equipment technology tree,

which has many branches such as industrial equipment, semiconductor equipment, medical equipment, etc.

For example, in industrial equipment, there are metal cutting, lathes, milling machines, pumps, compressors, fans, electric motors,

and the types are varied.

And semiconductor equipment includes single crystal furnaces, ion implanters, etchers, lithography machines, optical lenses, etc.

As for medical equipment, there are X-ray machines, CT machines, MRI equipment, blood analyzers, etc.

In short, basically all important equipment is in these sub-directories.

It's just that like the weapon catalog, the most advanced of these instruments are products of the 80s.

Take lithography machines as an example; they are still products of the micron era of the 80s.

Clearly, this kind of lithography machine can no longer keep up with the times.

Opening the material technology tree, various metals and alloys made Lin Yi dazzled.

However, special ceramics, carbon fiber, hydrogen energy materials, lithium battery materials, and graphene technology made Lin Yi very envious.

Of course, these are also material technologies of the 80s.

Among them, technologies like graphene, which was born after 2000, are still empty inside.

Lin Yi asked the system after unlocking these last time.

The result was that these sub-directory technologies all need money to upgrade the era.

And the amount required is consistent with the weapon catalog.

Still taking lithography machines as an example, upgrading to the 90s only costs 5 million US dollars,

but upgrading to the 2020 level requires 200 million US dollars.

Note that this is just unlocking era technology.

Specifically purchasing equipment still requires continuing to pay money according to different manufacturers and models.

However, even so,

Lin Yi is very satisfied with the system's functions.

This basically allows him to no longer need to purchase those advanced equipment from overseas that might be "choked."

As long as he upgrades and unlocks, he can purchase equipment beyond his era,

and even as long as the money is in place, some equipment that does not exist in reality and only belongs to the future will appear.

Of course, the premise of all this is having money.

Super-era technology, a 10-fold money multiplier is no joke.

However, from here, Lin Yi finally understood

why the system said it could accelerate the civilization process.

War and technology can be said to be the accelerators of civilization.

Of course, the premise is not to play too hard; the other side of war is destruction.

The next day, the world seemed to have no changes.

But compared to the nearly 6 billion people who knew nothing,

millions of people in this world witnessed an auction worth 12 billion US dollars last night.

The Ford-class aircraft carrier, this world's most advanced aircraft carrier, is like returning to its original owner,

about to return to the embrace of the Ugly Nation.

According to the transaction time agreed upon by Lin Yi and the Ugly Nation's network liaison,

this aircraft carrier will appear in the coastal area of the Ugly Nation in a week.

At that time, as long as the Ugly Nation drags the ship back, that's it.

By the way, the ship has no nuclear fuel and is just an empty shell aircraft carrier.

And after selling this aircraft carrier obtained from the lottery,

Lin Yi's wallet can be said to have bulged.

Because it was the Ugly Nation's money, he spent it quite comfortably.

As for whether that aircraft carrier will improve the Ugly Nation's combat effectiveness when it reaches the Ugly Nation, this is certain.

But the problem is, no matter how many aircraft carriers come near the Dragon Nation, they are just iron coffins on the sea.

With the current military strength of the Ugly Nation, the difference between having one more aircraft carrier and one less is not big.

In fact, the combat power improvement of a Ford-class aircraft carrier for the Ugly Nation is very limited.
