After the space is upgraded, Ye Quan no longer has to worry about how to green the newly expanded land, how to plant and breed to increase the spiritual energy value, etc.

Ye Quan asked, "How much is the spiritual energy value now?" ”

"You haven't been useful for more than half a year, plus what you have retained before, you have saved up to 213 million."

"It's still too little." Ye Quan sighed, 200 million psionic energy value was astronomical in the past, but as soon as the civilization level of the item was high, the price of exchange would increase by tens or even hundreds of times, and Ye Quan also needed to be careful in his calculations.

Lingxi said: "What do you want to exchange?" ”

"There are too many things I want to exchange, but I think the most important thing at the moment is that there is a universal machinery manufacturing base for the third-level civilization and a fourth-level civilization, and now that the earth has been shrouded in a crisis, chaos has appeared, I must make some preparations in advance."

Lingxi gasped, "Two universal machinery manufacturing bases, which add up to 336 million spiritual energy points!" ”

Ye Quan said: "Yes, I think this is the most cost-effective, it can be used in all aspects, with it, most of the fourth-level civilization products do not need to be exchanged." ”

336 million psionic points are enough to exchange for nearly two Tier 4 civilization's ultimate weapons, the Space Battleship, with such two powerful warships, they can dominate in the remote areas of the entire galaxy.

The previous universal machinery manufacturing base of the psionic space was only a second-level civilization level, and the products produced were more than a hundred years more advanced than those of other countries, and the psionic value only cost 800,000, and the manufacturing base of the third-level civilization was only 16 million, and the manufacturing base of the fourth-level civilization needed 320 million psionic value.

Ye Quan wants to let the human beings on Earth enter the space age as soon as possible, and not go around the solar system. Fly straight to a distant star field hundreds of light-years away.

To that end. You can only skip a vehicle that can't exceed the speed of light from a third-level civilization. Use the spaceship of the fourth-level civilization to travel faster than light through the warp engine, and go to Yanhuang Star for exploration and immigration.

The base of the fourth-level civilization can be used to build the most important power systems, control systems, weapon systems, and protection systems of spaceships.

The base of the third-level civilization is used to manufacture secondary components such as the hull.

As for the interior decoration with minimal technical content, it can be completely left to the outside world.

In this way, Ye Quan can build a spaceship that approves a fourth-level civilization in a short period of time, and if he keeps spending psionic points to exchange it, it is too cost-effective and impossible to do.

Of course. The universal machinery manufacturing base is not really "omnipotent", it can only manufacture about 90% of the four-level civilization products, and some products that are too large and have reached the peak of the four-level civilization at the scientific and technological level are not good.

The biggest limitation is that there are so few types of mineral resources on the planet that even 40% of the product range cannot be reached.

In order to produce more products of a Level 4 civilization, Ye Quan would have to expand his mining range to tens of light-years away.

Relying on the resources of the earth alone cannot support a civilization to enter the age of interstellar exploration.

Therefore, the improvement of the overall civilization level still has to be taken step by step, and you can take some shortcuts, but it is impossible to make a direct leap.

What's more, the universal machinery manufacturing base is like a relatively all-round production line. Even if it runs 24 hours a day, it can't avoid a capacity problem. If you produce this kind of product, you will occupy the production capacity, and you will not be able to produce anything else.

"Since there is still more than 100 million left, let's break down a batch of jadeite and diamonds."

Now the Hualong Kingdom, which is the former Burma Kingdom, has been completely controlled by the Black Dragon Army, and almost all the jadeite mines belong to Yequan and are being mined at full strength, while the small amount of jadeite flowing out of the Hualong Kingdom is actually man-made.

In addition, through various means, more than one-third of Africa's diamond production, as well as some diamond mines in Australia and Rakshasa countries, are controlled by Ye Quan's forces, and man-made diamonds produced by high technology are also used to replace the market.

Therefore, there are now more than 400,000 tons of jadeite and more than 500 million carats of diamonds stored in the space, as well as a large number of other jades, gemstones and crystals, which are equivalent to more than a billion spiritual energy values, in case of emergency.

Ye Quan dismantled the jadeite and diamonds worth more than 140 million spiritual energy and exchanged them for two universal machinery manufacturing bases.

The shape of the universal machinery manufacturing base is similar, like a semi-circular cover, but the higher the civilization level, the larger the area occupied, the fourth-level civilization base covers an area of nearly 6 square kilometers, and the height is more than 1000 meters.

The interior of the site is divided into more than 1,000 functional areas, where various raw materials are melted, formulated, processed, manufactured and assembled.

Now that the base is in hand, Ye Quan has too many things to make in addition to ordering the production of the core components of the spaceship.

For example, Ye Quan wants to establish a "galaxy monitoring system" through unmanned observers, space telescopes, energy monitoring, light wave scanning and other means, and the first step requires that the star field can be observed at a distance of trillions of light-years, and can monitor any movement within 200 light-years of the solar system.

Ye Quan also wants to form a space fleet as soon as possible after completing the earth defense system, build a peripheral space fortress, and build a defense system for the entire solar system.

He even asked for the production of a batch of intelligent robots.

YD-60 liquid robots like Rogues are almost "immortal", with comprehensive capabilities and amazing combat power, but the level of science and technology is also a fourth-level civilization.

Niu B's Transformers, if Ye Quan is willing, can also be produced through the manufacturing base of the fourth-level civilization, and the combat effectiveness is even more powerful than in the movie.

First of all, a batch of underwater robots at the level of fourth-level civilization were created, which were much stronger in combat than those produced by the Crystal Palace itself, and could be used to hunt sea monsters, open up safe passages, and guard major mining sites and submarine bases.

In the coming months, nanorobots for special operations, large anti-gravity robots for land attack, all-round combat robots with the ability to fly more than 10 times the speed of sound, super robots with space combat capabilities, etc. will also be produced.

These robots will form a legion and serve as Ye Quan's strategic reserve force on Earth to deal with various crises that may occur.

Leaving the space, Ye Quan did not return to Taoyuan Village first, but went to a seaside storage area in Jiangning City and received a batch of hundreds of tons of raw materials; Then he went to the Crystal Palace base and received tens of millions of tons of purified metal mineral resources, which are the raw materials for the production of the three universal machinery manufacturing bases.

There are also hundreds of frozen sea monster carcasses that can be used to decompose, because it is difficult to captive and control, and only 9 sea monsters have been captured alive so far, and they are all small cubs.

Ye Quan even released two sea monsters into the ocean of space, wanting to see how far these sea monsters could eventually grow.

Governments around the world, including some qualified private scientific research institutions, are conducting research on sea monsters in all aspects, and the marine research center at the Crystal Palace base is the most technologically advanced and has achieved the most results, and has even disclosed many studies to the outside world, and officially named the sea monsters that have obviously been artificially modified as "biochemical beasts".

The largest scientific research results show that more than 99% of the biochemical beasts on the earth are not yet adults, and once these biochemical beasts reach adulthood, they will have energy attack and defense capabilities, and at that time, the difficulty of destruction and the destructive power caused will increase exponentially.

These cyborg beasts can continue to grow as long as they have enough food, and they don't have much weakness, and if they want to destroy them, they can only rely on weapons in the hands of humans. (To be continued......)
