It was two days of deliberation.

After many discussions with artificial intelligence Alice and Nuwa, Chen Jin made the final decision.

Make!

Starships, they must be built.

But instead of starting to build right away, wait until you have enough resources at hand to start building.

The estimated start date is expected to be in 7 years.

The construction period is about five years, about the 12th year, and in Chen Jin's hands, he will be able to have the first F-class interstellar battleship (F-class, the weakest class).

The largest number of ships will be built, which will be used as a scientific research test ship to test the power system, weapon system, and control system, and serve as a test platform to test various technologies...... It provides valuable data support for the development of more powerful warships of the next level.

Yes, the realism of the virtual game "Galaxy Home Online" is more than 99.9999%, and the "Prototype No. 1" battleship designed by Alice can theoretically become a usable battleship in reality, but no matter how realistic the virtual environment is, infinitely close to reality, there is still a certain error.

There is about a one-billionth error.

There will be no big problems on such a device with a small error, but on a large and complex device like a starship, the error will be relatively large.

If it weren't for the construction of a "prototype No. 1" battleship in reality, obtaining a large amount of real data, and correcting errors, Alice is unlikely to develop a more advanced starship.

So, prototype No. 1, must be built!

But due to the weak combat effectiveness, at most one was built, and on this basis, the "prototype No. 2" with stronger combat effectiveness was developed.

If the strength of the prototype No. 2 is strong and meets the needs of use, then several more ships will be produced and put into service in batches.

If the strength of Prototype No. 2 is relatively weak and cannot meet the needs, then only one can be produced as a scientific research platform to assist in the development of "Prototype No. 3".

Until the first type of interstellar battleship with combat effectiveness that satisfies Chen Jin!

Then the production capacity will be exploded, and the quantity will be mass-produced to be sufficient.

This development model is called "small steps and fast running".

Having said that such a development is a bit too "petty", in case the danger suddenly comes, and there are not even a few decent warships in hand, what can you use to resist the opponent?

In fact, Chen Jin thinks about it this way, and he has a reason.

Because there is a concept of "generational difference" between weapon systems.

For example, swords and strong bows are to stones and sticks.

For example, rifle artillery is for heavy cavalry.

For example, airplanes, tanks, and linear arrays.

For example, the nuclear bomb, the final weapon, is a conventional weapon.

There is a huge generational gap in between.

In the event of a collision, the exchange ratio will not be 1 to 1 to 1 or 1 to ten, but 0 to infinity.

The strongest weapon of the same generation, in the face of the next generation of "weapons", will be immediately beaten and eliminated.

For example, the "Prototype No. 1" battleship designed by Alice, if you are facing an E-class battleship with a combat strength of more than 10, it will be difficult to see the exchange ratio above 0:10; If you encounter a D-class ship with a generation difference, the exchange ratio will exceed 0:100.

Therefore, no matter how many technologically backward starships there are, they are not as good as the most advanced ones.

Under the premise of rapid development of technology, taking the road of small steps and running fast is the best choice to avoid the waste of resources and obtain sufficient self-defense capability as soon as possible.

Before a warship with satisfactory performance is successfully developed and produced, there is only one measure that Chen Jin can take to defend itself in the long gap between it -- early warning.

"Alice, your top priority is to develop an early warning satellite, produce hundreds of thousands, and then let the Nine Heavens Xuannu take these satellites and release them to the periphery of the planet Helfa, and establish an early warning system, the wider the monitoring range, the better! At the very least, we have to be able to spot the enemy when they come in, so we have enough time to deal with it! Chen Jin said.

"Good master, I will immediately start the development and production of early warning satellites and establish a perfect early warning system." Alice said.

Nuwa said that with the base's current technical capabilities, the early warning system established can cover all corners of an area with a radius of 100 astronomical units, and with the propagation speed of electromagnetic waves, this is equivalent to 13.8 hours of early warning capability.

13. Hours?

Chen Jin nodded, for most of the day, there may not be a way to defeat a strong enemy, but there is no problem in running to the other side of the earth, rolling up his belongings and running.

Even the nearly 30,000 tons of gold accumulated in the Dakeng base can be moved to the other side of the earth......

"Anyway, why do I always think about running away?"

Chen Jin shook his head vigorously, those mysterious and powerful forces made him a little nervous, he actually just wanted to plant fields with peace of mind, and build the planet of Helfa a little better, and didn't want to provoke any forces.

But after witnessing the situation after the destruction of Planet Helfa, no matter how big he was, he didn't dare to take any precautions.

Even he had a vague premonition in his heart that the idyllic time of quiet development would not last forever, and those mysterious and powerful forces, he would deal with them sooner or later, and there would be conflicts, collisions, and even life and death, and finally the winner and loser.

Chen Jin will also experience these collisions, with all kinds of forces.

Because he will live until that time.

In the research area of the Dakeng base, one of the medical research institutes has recently successfully implemented a medical technology based on the collected technical data and medical equipment.

Risk-free life extension technology!

It is possible to extend the life expectancy of human beings to about 220 years without any medical risks.

The specific principles of life extension include "enhancing cell activity", "prolonging DNA telomeres", "enhancing cell antioxidant capacity", etc., and a variety of effective pharmaceutical ingredients are all contained in a light golden liquid of "life extension injection".

After one injection, the effect is extremely obvious, and in just a few days, you can find that the person has become younger, the skin is smoother and firmer, and the body is full of vitality.

With just such an injection, the effect is only three months at most.

Unless you get an injection every three months, in the long run, you will not only live to be 220 years old, but you will also be young and beautiful forever.

But the cost is extremely high, and the cost of injecting a "life extension injection" requires a full 100,000 meters of gold.

Four needles a year, that is, 400,000 meters of gold...... And the annual income of the vast majority of ordinary people will not exceed 300,000 meters of gold.

Therefore, this is destined to be a medical service that only the rich can afford.

However, the artificial intelligence "Crimson" (Crimson was not formatted, and Crimson was reactivated after Alice entered 'Sakura') said: "The production cost of life extension needles is very low, up to 10 meters of gold needles, as long as the raw materials are sufficient, the base can be mass-produced." ”

How much does 10 meters of gold cost?

Chen Jin shook his head: "The profit of this thing is more exaggerated than drugs!" The pharmaceutical company called 'Angel' has a darker heart than a drug dealer. ”

Now this kind of life extension needle base can be produced, not to mention an injection every three months, and there is no fear of waste every day.

However, the effect of life extension needles can only be maintained until about 220 years old, beyond this age, more and more toxins and heavy metal elements accumulated in the human body will reach a life-threatening level.

If you want to prolong your life, you must go to a lunar convalescent facility or a space hospital to receive "low-risk life-prolonging treatment" in microgravity or zero gravity to remove all kinds of toxins from your body.

After the toxin is eliminated, the life expectancy is extended to 300 years, and there is basically no problem.

After a person's lifespan is 300 years old, if he wants to prolong his life, the medical risks he faces will gradually increase, but he has the means to do it.

However, the history of the development of Helfa Planet is not long, until the destruction of civilization, the longest-lived rich man is only 289 years old, and he will never have the opportunity to use medical technology to extend his lifespan for more than a thousand years.

Therefore, Chen Jin wants to prolong his life to more than 1,000 years, and this kind of medical technology can only be developed by himself.

But all in all, immortality is not a delusion for him, but completely achievable.
