Humanity is missing, luckily I have billions of clones.

Chapter 165 Great Development of Science and Technology

Excessive gravity is extremely harmful to the human body.

It not only causes mechanical injuries, such as muscle strain, bone injury, and internal organ damage, but also seriously affects the human body's endocrine system, nervous system, etc.

The key is that the high gravity on Jupiter does not last for a moment and then disappear like the acceleration of a spacecraft, but exists forever.

As long as you get within a certain range of Jupiter, you cannot escape this influence.

If a clone stays in this environment for a long time, it will become disabled in a few years.

Therefore, in order to maintain the operation of this energy collection system, Li Qingsong had to have the clones adopt a rotation system, working on Jupiter for a period of time and then withdrawing to recuperate.

But even so, on average, hundreds of clones die or become disabled due to gravity every day, losing their value and having to be destroyed.

The losses in the Jovian system were indeed heavy, but could this be an obstacle?
Li Qingsong’s answer was no!

Compared with the journey of developing the entire solar system, compared with one's own technological progress, compared with the operation of factories, what are dead clones and destroyed planes?
I can afford the loss!
Even in this situation, supported by the endless supply of deuterium from Jupiter, Li Qingsong's entire industrial system was operating vigorously and technology was rapidly improving.

At this moment, controlled nuclear fusion technology is close to maturity and has entered the stage of large-scale application. The only thing that has not been conquered is miniaturization.

With the guidance and information from the Blueprint Man, Li Qingsong already has a specific idea and believes that a breakthrough will come soon.

While conducting research on controlled nuclear fusion, Li Qingsong was also simultaneously conducting research on another crucial technology.

High-speed ion propulsion technology!
Like controlled nuclear fusion, high-speed ion propulsion technology is also one of the essential technologies for interstellar travel.

Secondary pressurization propulsion technology still requires a huge amount of chemical fuel as a working fluid, which is unthinkable in interstellar travel.

Because no spacecraft, no matter how big, can carry that much fluid.

At best, it can only be used for navigation within a solar system, as it is now.

Li Qingsong had also begun researching high-speed ion propulsion technology long before the Blueprint people arrived.

But the research at that time could only push a piece of paper at best and was completely impractical.

Since defeating the Bluetuk civilization decades ago, capturing enough Bluet people, and obtaining a large amount of scientific and technological information, high-speed ion propulsion technology, like controlled nuclear fusion technology, has also made rapid progress.

From the initial ion injection speed of only 30 kilometers per second and the total thrust being only enough to push a piece of paper, the continuous advancement of technology has allowed its thrust and efficiency to gradually increase.

Kilogram-level thrust, ton-level thrust, hundred-ton-level thrust, ion injection speed increased from the initial 30 kilometers per second to 100 kilometers per second, 500 kilometers per second, 1000 kilometers per second...

After decades of all-out development, Li Qingsong's ion propulsion technology can now eject ions at a speed of 1500 kilometers per second, thereby obtaining a large amount of reverse thrust. It can even propel a Mercury-class spacecraft with a mass of tons, and its maneuverability is no worse than when it used secondary pressurization propulsion before!

But this isn't the end of the road for ion propulsion technology. Compared to secondary pressurization propulsion, which has reached its technological limit and is virtually impossible to improve due to the laws of physics, there's still significant room for improvement.

Especially when combined with a small ship-borne nuclear fusion device, high-speed ion propulsion technology has been greatly enhanced. Now, it can be applied on a large scale!

Therefore, Li Qingsong's spacecraft system underwent a comprehensive upgrade.

All cargo ships, scientific research ships, exploration ships, passenger ships, etc., which have been replaced with controlled nuclear fusion power, have all had their secondary pressurization propulsion modules removed and replaced with high-speed ion propulsion modules.

In addition to warships, Li Qingsong owns tens of thousands of spaceships of all sizes. The nearly one million high-speed ion engines equipped on them are working almost all the time, constantly feeding back huge amounts of work data to Li Qingsong, providing support for subsequent improvements and upgrades.

Ion propulsion technology, like the miniaturization of nuclear fusion reactors, has currently reached a bottleneck. However, this is not a problem; there are no fundamental obstacles to its continued development. As long as research continues step by step, performance can be continuously improved.

In addition to these two most critical technologies, Li Qingsong also digested and absorbed the knowledge that originally belonged to the Blueprint people in high-speed layered scanning radar, high-speed electromagnetic gun, high-power laser gun, materials science, etc., and integrated it into his own system at a speed that shocked the Blueprint people.

Time passed by little by little, and in the blink of an eye, another 20 years had passed.

At this moment, a small warship with a total fully loaded mass of only 300 tons appeared in the spacecraft assembly plant and appeared in front of Li Qingsong.

After ignition, it suddenly climbed into space at an incredible speed and disappeared from the clone's sight.

Driven by its bright blue tail flame, it deftly maneuvered through space, its high-speed layered scanning radar continuously scanning all movements in the surrounding space.

Supported by high-speed bogies, the electromagnetic cannon unleashed projectiles at a rate far exceeding previous speeds, reaching speeds exceeding 20 kilometers per second. High-powered laser cannons unleashed destructive laser beams, scorching everything in their path, visible and invisible...

Looking at this latest Mercury-class battleship, Li Qingsong's heart was filled with joy.

At this moment, all performance indicators of this Mercury-class battleship have fully reached the level of the battleships of the Bluetook civilization, and in some places they are even slightly higher.

The birth of this Mercury-class battleship means that its technological level has fully caught up with the Bluetook civilization!
Even if another Bluetook civilization in its heyday comes, he can destroy it.

Although we have the same technological level, our industrial production efficiency is many times higher than theirs.

This means that I now truly possess the ability to travel across the stars.

That being the case...

time to go.

We have already wasted so much time. If we don’t leave now, we may not be able to leave.

So, build a fleet.

Let's build a real interstellar fleet that can truly handle the interstellar range of several light years or even dozens of light years, which is tens of trillions or even hundreds of trillions of kilometers when converted into kilometers.
