"Ahh It's so embarrassing, you solid creatures seem to look the same thing, I'm afraid it's too late to change the name now, and the name Qichen is also very good! ”

Ruan Lin had a rough guess: they did hide something, and then thought of what they said at the beginning, "The last time we met, it didn't go well." ”

There is no need to wishfully assume that the cognitive bias of the Seck civilization, if this sentence is really just a literal meaning, then the ship called the "Dust Civilization" is no different from ours.

The design and development of the ships of this civilization are exactly the same as those of the current civilization on Earth?

This is obviously impossible.

Ruan Lin decided to get to the bottom of it:

"Qichen Civilization, what is the relationship with you?"

This time the wait lasted more than ten minutes.

"They have known us for a long time, and we thought that your meeting with us would be an unexpected encounter. I'm so sorry, but you are indeed another civilized race, thank you, Earth Civilization! ”

It seems that the Seck civilization is simply indistinguishable from the appearance of physical ships, which is equally unimaginable.

They then sent another message:

"Thank you again, dear Earth Civilization! May the currents keep you from falling. ”

Ruan Lin laughed from the bottom of his heart, this is just a small blessing, but it can also make the incomparably cold starry sky warm up a little.

Perhaps, this is what the galaxy should be, giving up endless suspicion and killing, and some small help can also move other civilized species.

"Wit, let those ships come back."

If you want to realize the galaxy system one in your heart, you still need to work steadily and develop yourself.

Ruan Lin continued to order: "WIT, the Titan needs to vacate the space of two light calculation planes inside the Titan and remove the redundant internal facilities. ”

"Okay, Dr. Nguyen."

With the precedent of the first light-volume computer, the construction and commissioning of the second computer took only three years, during which the Seck civilization did not communicate with Nguyen Lin, and they should have developed steadily.

And today, it's the day to move into a new home.

Under the lifting of dozens of cranes, a light computer slowly approached the Titan, followed by the supporting "Little Black House".

Ruan Lin planned to move the original quantum computers to the surface and perform some simple logical operations.

The robots inside the Titan are still busy dismantling, and they are dismantling the small dark rooms of the two quantum computers and placing them outside.

With the quantum computer completely exposed, Ruan Lin finally ordered: "WIT, turn off the liquid nitrogen refrigeration, stop the operation, and the transfer of data is about to begin." ”

After the two old and new computers were docked, the data of WIT began to be transferred.

The data transfer took a full 5 hours, and the WIT announcement rang out again: "Thank you, Dr. Nguyen. I'll help you with the hosting transfer next. ”

Ruan Lin also successfully moved into his "new home" with the help of WIT.

He ran the password sorting test again, and the solution process was very different from before, the calculation was no longer just a 0 and 1 superposition, but an extra calculation between 0 and 1 on the way to 0 and 1 overlay.

Nguyen Lam decided to move on to the next stage of his goal: the transformation of a controlled nuclear fusion engine.

Looking back, thousands of years have passed since leaving the solar system.

On a spatial scale, he is 22.7 light-years away from the solar system, compared to the 100,000 light-years diameter of the Milky Way.

And within 65 light years around, except for a few civilizations that he has come into contact with, there is already a dead silence.

It would take 3,145 years to get out of this uninhabited area at a limit speed of 6,200 km/s, and this is when the fleet does not stop, in fact, each deceleration takes a lot of fuel, and it takes a long time to refuel the journey.

Optimistically, it would take at least 4,000 years to cross 65 light years, which is extremely unrealistic.

Ruan Lin manipulated his body and walked into the laboratory again, and he already had an idea for this engine transformation.

The problem is that a large part of the ship's transportation space is used to carry fuel, which has led to a significant reduction in the transportation space for other supplies.

Previously, the collection of atomic remains took up only 30% of the ship's interior space, and 42% of the interior space was used to load controlled nuclear fusion fuel.

If a controlled fusion engine needs to carry fuel at all times, then the Bassard ramjet is a local source.

He also envisioned replacing the engine, and the "Bassard ramjet" was currently the easiest for him to achieve, but after careful consideration, he abandoned the change.

This idea seems feasible, but it is actually too inefficient to be realistic at all.

And the alternative "fuel-free EM engine" was also falsified as early as the age of the earth.

As for the curvature drive and short-distance jump engine, Ruan Lin has not even fully developed the relevant theories, let alone the relevant substances, just like the era when the automobile first appeared, people fantasized about the 21st century cars flying in the sky.

The only thing that can be done now is to tinker with the controlled fusion engine, but the research on the new engine cannot be left behind.

"It seems that there is still a long way to go before we can realize a non-working quality ship."

Ruan Lin is still optimistic about this, and the boat will naturally go straight to the bridge.

There are two main points for the transformation of the controllable fusion engine: to speed up the exhaust gas injection and to minimize fuel consumption.

Within a few days, a controlled fusion engine appeared in the laboratory, and Ruan Lin decided to extend and amplify the entire engine.

The internal magnetic coils have been lengthened by Ruan Lin to 1.2 times the previous size, and they are now several times more binding on the plasma.

The magnetic nozzle in the tail has been thickened, and now as long as there is enough fuel, the exhaust gas will be sprayed faster, the reaction force will be stronger, and the speed of the ship will be faster!

Ruan Lin envisioned that the ship's tail gas would eject at about 21% of the speed of light in a vacuum, and that the final velocity would be 10% of the speed of light in a vacuum.

According to the rocket formula, it costs 5.664 tons of fuel for the ship to accelerate to 10% of the speed of light in a vacuum.

This is already the result of improvements, and it is almost impossible for these figures to be improved again.

Even if it can be improved, the fuel consumed is still unimaginable.

According to this calculation, the consequence of the ship's speed increased to 30,000 km/s is that the Earth's civilization fleet will have to refuel almost every star system it visits.

This is the price of increasing speed, and there must be a trade-off between the two, increasing speed or reducing fuel.

The controlled fusion engine needs to be put to the end for the time being, and accelerating the ship to 10% of the speed of light in a vacuum is already its limit.

And the research and development of new engines also needs to be put on the agenda.
