Chapter 228 The Vast Sea of ​​Stars

The Hundred Years Plan has increased the size of the human fleet from a few mountain-class warships to a thousand lake-class warships. Together with other types and functions of spaceships, the total number of human spaceships is as high as 1,300.

This is only the lake-class warship level. If the mountain-class and small frigates are included, the size of the human fleet has reached 2,000.

During this period, humans also upgraded the residential spaceships. Well, it is not an upgrade, but because of the improvement of shipbuilding technology, larger residential spaceships were built.

A new residential spaceship can accommodate 500,000 residents. It can be said that a ship is a town. Humans have 150 such spaceships, of which 110 have been filled.

That is about 55 million people, plus the number of soldiers on each warship, the human population has now reached almost 60 million.

The preset departure time soon arrived.

Yue Yuan also returned to the internal bridge of the Tianqin, preparing to issue the departure order.

Before this, humans had packed all engineering ships, scientific research ships, biosphere spaceships, and various ground facilities.

As early as a year before the departure of the large fleet, a batch of unmanned exploration spaceships had set off first. The fleet is the whole of the new human civilization, so we can't set off rashly. It is very necessary for the exploration spacecraft to go first.

"Connect the whole fleet communication and issue the departure order!" On the Tianqin, Yue Yuan turned and floated to the commander's seat, and said to the communication personnel at the same time.

He had already done the mobilization for departure. In fact, humans don't need any mobilization for departure in their current state. He just said a few simple words to express the sense of ceremony.

As the order was issued, the huge fleet adjusted its posture and kept pace with the entire fleet.

The ship personnel also returned to their positions as before, ready to meet the upcoming acceleration impact.

Because it was a normal departure, the fleet did not pay attention to the acceleration buffer and did not enter the overclocking mode. After all, the preset acceleration was not large, and it could be completely withstood by the hard flesh of humans.

At the moment the fleet set sail, the long tail flame of heavy nuclear fusion first illuminated the surrounding asteroids, followed by the explosive pulse propulsion of the cold nuclear pulse engine.

"Goodbye, Aldebaran!" Looking at the gradually shrinking Aldebaran on the external screen, many people silently said in their hearts.

The huge human fleet, driven by two propulsion technologies, slowly accelerated from a relatively static state, 1% light speed, 2% light speed, 10% light speed, 15% light speed.

In the flashing cold nuclear pulse explosion, the fleet easily broke through the 15% light speed that the first-level civilization could not break through, and then continued to accelerate, 16% light speed, 20% light speed, 25% light speed, until 30% light speed, the fleet began to enter the uniform speed stage.

Of course, if the thrusters continue to be turned on, the fleet can still continue to speed up, but since it has almost reached the maximum speed of the cold nuclear pulse's reverse thrust particles, the cold nuclear pulse can no longer provide too much power to the warship. It is of course possible to continue to accelerate with light pressure alone, but the "no-fluid" thrust brought by that little light pressure is already a drop in the bucket for the huge warship.

So 30% light speed, like the 15% light speed of the first-level civilization at that time, has become a thick speed barrier standing in front of all second-level civilizations.

As the dual-core engine gradually shuts down and the secondary engine maintains thrust, it also marks that humans will enter a long voyage again.

In such a voyage, humans can naturally live normally, but in the vast sea of ​​stars, the safest thing is hibernation. Because all the supplies and fuel on the warships are prepared for navigation, not normal life.

In order to reduce unnecessary damage, hibernation is naturally the most suitable.

Of course, this is also related to the new human's goal of running to a farther star field.

The rotation duty system is activated again.

Humans, no, it should be said that new humans, have once again embarked on a long journey to the stars.

New humans, since the overclocking mode technology has been fully opened, humans have realized that they are really different from before, so they gave themselves the name of new humans.

It is indeed a new human. As far as Yue Yuan himself is concerned, he now has more than the strength of the first physical enhancement. When the overclocking mode was popularized by the whole people, he also gave himself an overclocking mode transformation.

To be honest, Yue Yuan's control talent in overclocking mode is not bad. Just after the transformation, he can easily control the entry and exit status freely.

After several days of training, he has mastered the switches of various parts. Of course, because it is activated by the "goose bumps" mechanism, this "part" will not be accurate to a small area, at most it is only large parts such as the upper and lower body, hands and feet.

In addition to the overclocking mode, Yue Yuan also underwent bio-alloy bone transformation like other soldiers.

The change stage of this transformation is different from the overclocking mode, which completes the energy supply through injection and overeating. Because it is a bone change, it is more troublesome.

The person who undergoes the transformation must undergo the first stage of genetic transformation so that the body can generate some cells that can use metal elements. After that, he must regularly inject himself with a metal-rich injection for a long time.

This injection period will probably last for one to two years.

In fact, the original plan took longer, but later scientists suddenly had the idea to combine the Kuntai people's "abnormal development" technology with this bone metabolism transformation, which shortened the transformation time to two years.

The bio-alloy bone transformation technology is naturally derived from Wolf's biosphere research, which is based on the biological genes with a steel appearance.

Of course, as a human body transformation, it naturally cannot become a real steel skeleton, after all, steel is too easy to attract magnetism.

So after countless experiments, the new humans have made many kinds of deformations, among which the best one is an alloy with a high titanium content.

It is considered a titanium alloy.

When this transformation is carried out, the original human calcium skeleton will be slowly replaced by titanium alloy. The person who completes the transformation will have a titanium alloy skeleton.

Combined with the overclocking mode, it is really superhuman.

Of course, the alloy skeleton transformation is naturally impossible to only involve the skeleton. After all, the skeleton has changed, and the weight will naturally increase. The ligaments originally used to drive the calcium skeleton will of course be overwhelmed, so this transformation actually involves the skeleton and various parts connecting the skeleton.

The technical difficulty is very high.

However, during this hundred years, the accumulation of the new humans in Wolf's biosphere research and the Kuntai people's biotechnology research results have created new sparks, allowing the new humans to make rapid progress in human body transformation technology. Various related human gene transformation technologies have sprung up like mushrooms after a rain, allowing humans to master these various body transformation technologies.
