Joan of Arc stood outside the hull, in a weightless environment, she calmly suspended in mid-air, commanding a large wave of skilled workers, she patiently recited: "The hull part of the spacecraft is a double-layer armor with a thickness of about 350mm+800mm, using 75% of molecular-grade materials mixed with ordinary alloys, and the total weight accounts for 35% of the total hull, which can be said to be the most important part of the ship." ”

"For this part, our process indicators are that there must be no more than 50 impurity molecules per unit area of the material, and the degree of molecular dislocation must not exceed 0.01%, and everyone must be proficient in vacuum processing technology to make the spacecraft perfect."

It is impossible to imagine how much it would cost to build such a spaceship a few decades ago, at least 5 trillion, which is enough to exhaust the GDP of the East Galaxy for a year, and it is impossible to fight even a war.

Times are changing, since the research department overcame the difficulties of biological machines, and Cao Chuan accidentally created molecular machines, the price of molecular grade materials has plummeted to the extent that they are acceptable to ordinary wealthy people; Similarly, the scientific community and quantum computers have discovered new molecular-scale materials with different properties that can replace traditional materials in more contexts.

Naturally, a spacecraft like Galaxy Echo will use all molecular-level materials, but on the contrary, it will bring higher performance data, and there is a way to complete a jump of more than 10 times, with the speed of conventional space, so that the spacecraft will officially reach the speed of light.

On the other side, Nana is responsible for "supervising" the internal structure of the Galaxy Echo, a spaceship cabin with a variety of functions, especially this kind of nearly 300-meter-long big guy, the function is as complete as a city. It is a great test of people's overall planning ability.

She strolled down the makeshift aisles, "Remember, all the cabins have to be tested to make sure they're of the right quality." ”

In the past few weeks, she has found a lot of technical workers who have made mistakes in construction, so much so that everyone is extremely afraid of this loli. Think of her as if she were a demon.

White Lotus is responsible for the installation and commissioning of weapons and equipment, as humans go deeper into the universe, the greater the probability of encountering aliens, whether it is the ubiquitous unknown, or the alien creatures that have not yet given birth to intelligence, or other aliens with all kinds of strange shapes, once the force is used, weapons and equipment are necessary.

For example, the Galaxy Echoes is loaded with two 500-ton Dawnhammers and a deathlight cannon. In addition, the gun barrels neatly arranged on both sides of the hull, front and rear, and up and down, and the import and export of unmanned units, from the perspective of comprehensive combat effectiveness, are not much different from the Changyang-class flagship developed several decades ago.

With so many weapons and equipment, it takes time to gradually move from installation, to commissioning, and even to coordinated operations. But only by doing this well at the time of manufacture can we not drop the chain in a real war.

In the beginning. The engineers and skilled workers who had never worked with them did not approve of the guidance of the 3 Lori, and Pluto was relatively closed to the news, so they didn't realize what the real body of the 3 Loli was.

Only an old engineer who has worked in the factory for decades will find the nightmare of decades ago from Nana's voice and demeanor, the girl who once "supervised" the construction of the Queen Nana.

The old engineers, of course, will not tell this secret to the youngsters, this is their black history. Therefore, the young man is unknown, trying to challenge the authority of the three loli.

However, when they discovered that Lori's understanding of science and technology was far above theirs, and she was even more omnipotent, surpassing them in the spaceship assembly they were best at, the sense of superiority in the hearts of these challengers was immediately suppressed. The only way to do this is to follow the command.

Inside the shipyard, Nana is still reviewing the progress of building the spaceship. An engineer approached and said anxiously, "Miss Nana, there is a serious problem, the ship's reactor has been inspected and found to be flawed. ”

"Is it an inferior product?" The corners of Nana's mouth lifted slightly.

"No!" The engineer wiped the beads of sweat from his forehead, "It should be radiation contamination that caused the materials of the reactor components to decay into something else that should have been well preserved." ”

"This is not easy to do, the fusion energy reactor of the Galaxy Echo is specially built, do you have to wait for half a year to rebuild it?" Nana was a little dissatisfied, "When the time comes, we must investigate the responsibility of the party who caused the problem." ”

Her stern expression made the Engineer even more nervous, and she said, "But now... I think the host has a way to solve the problem. ”

Nana contacted Cao Chuan and told him the cause of the incident.

Cao Chuan looked inexplicable: "So, what is the use of expecting me for this kind of process problem?" This is not something that can be solved by rule simulation. ”

Nana said, "Isn't there a molecular manipulation by the master? Filter out the decayed impurities, and the reactor will be fine, and it will save time. ”

Cao Chuan has to admit that her words are really right, but unfortunately I always feel like I am being called as a coolie, but who called the brain domain to be developed a few times, and the 3 Loli have not gained any ability, but the evolution of the brain domain part is higher?

Although there is no ability, after the development of the brain domain, the speed of human thinking, memory, reflexes, and energy will rise significantly, basically the IQ limit of ordinary people is 250, after the development of the brain domain, the IQ will rise to 1000, and the benefits are very obvious.

In fact, Cao Chuan originally wanted to let them get some interesting abilities, such as "super electromagnetic cannon", "vector manipulation", "unyuan matter", "atomic collapse", "mind mastery", "absolute stationary", "telekinetic cannonball" or something, but unfortunately, a few loli were interested, and the problem was that no one had the time to wash the ability repeatedly, so they still gave up.

"Well, if it is a reactor, according to the harsh process requirements, in fact, there is a problem with a certain number of molecules on the surface, which affects the operation of the reactor, and it can be done in about two weeks."

Cao Chuan comforted himself with this, he had tried ability development, and as a result, the efficiency of his current molecular manipulation ability was several times higher than in the past, and the workload was actually not large.

Cao Chuan expected that the Galaxy Echo would probably take about half a year to build, although it was a long time, in fact, he had important things to do.

That is, you have to deal with the internal affairs of the solar system, and if you leave a mess, it will definitely make people complain. (To be continued.) )
