Of course, Li Yi understands the truth of specialization, and he also knows that even if he is a demon who knows business, if he is so scattered to study, he may seem a little mediocre for a long time.

But Li Yi thinks that playing through is not just playing?

Is it necessary to specialize in one with some purpose, and then to satisfy your ignorant vanity?

Everything in this time and space, whether it is the land war mode or the space star war, whether it is the development of resource planets or scientific research and manufacturing, and even the various influences brought by the knowledge of business, are extremely novel and interesting experiences for an earth traveler, and he doesn't want to go too fast, so as not to miss too many scenery.

Anyway, the life span of human beings in this time and space is very long, Li Yi is not in a hurry now, he is not in a hurry at all, he has a lot of time to develop comprehensively to experience and enjoy the life of the new time and space, not to mention that with his own knowledge and quotient, it is also very fast to make up his mind to specialize in a certain item, and now let those natives mistakenly think that he will be greedy and not rotten, which can also dispel the vigilance of these people.

After completing the handover task of Li Yi's fighter chip, Althea led Li Yi on a sightseeing tour in Manning Space City.

The so-called space city, in fact, is a super starship, but the scale is very large, by analogy, the area is equivalent to a second-tier city in China on the earth, of course, because it is three-dimensional, so the facilities inside far exceed the capacity of the second-tier city, all kinds of work, life, entertainment service facilities are available, can accommodate more than 30 million people.

Since it is a super starship, it can naturally fly and move in space, but because the mass is too large, it can be converted according to the mass-energy equation, and the energy consumed by the space city is astronomical if it wants to move or change direction, and it is difficult to maintain a large acceleration.

Of course, even if you accelerate to a speed of 350 m/s and enter the jump state, once you get out of the jump state, it will take several hours to slow down to 0 m/s and hover to a standstill - this is a very dangerous behavior, it is very likely that you will hit a planet headlong after the jump, or rush out after arriving at the battlefield and there is no turning back.

Therefore, Space City is generally only attached to a certain planet in a high orbit and flies, rarely going out to participate in combat, which can be regarded as a huge artificial satellite and space fortress.

In fact, due to the synchronous orbit of Althea Star in the high orbit of Manning Space City, its speed has reached 18.3 km/s, which is the first cosmic velocity of the Manning Galaxy, below this speed, Space City will gradually double the gravitational pull of Althea back to the ground, above this speed, it will get rid of its gravitational pull and fly to the Sun of Manning System.

How the space city was accelerated to this speed and how much energy it took to maintain this speed, Li Yi didn't know at all, he still had a lot of knowledge to learn, but at least he understood one thing - the space city was not built on land, but directly in space.

In fact, not only space cities, almost all starships are built directly in outer space, and the starships in the old time-space movies and novels can fly directly from the planet land to space and directly from space to land landing, although they exist in this time and space, they have not reached the level in the movie.

In fact, people with a little scientific knowledge know that the mass-energy equation determines that it is difficult for massive objects to resist the gravitational force of the planet and fly into space, because the energy required is really astronomical, which is not economical, and the requirements for various technologies are extremely high, which is completely unnecessary.

So in this time and space, let alone the space city, that is, ordinary mining ships and assault ships cannot fly from land to space, let alone landing, whoever dares to do this, entering the atmosphere will become a meteor on fire, because when the starship is manufactured, the outer wall titanium alloy material is only suitable for the space environment, not for the high-temperature environment of friction into the atmosphere.

Of course, the problem of outer wall materials can be solved, but even if it is solved, the landing starship will eventually turn into a huge meteorite and smash directly on the ground, because the ion engines and solid fuel engines installed on these starships cannot stop the gravitational traction at all, and will only fall like a free fall, and then it will definitely be the end of the ship's destruction and death!

Of course, with the technology of this time and space, it is possible to build some dual-purpose starships with very powerful engine power, this thing does exist, and it is indeed the main way for human beings to enter space or land on planets, but the volume and mass are much smaller, just airship-level landing craft, specially used as a means of transportation to space or landing planets, and space starships in the real sense are almost without exception unable to directly land on planets.

This is also why the Watson family built three giant towers directly to outer space in Alktic City, although this miraculous project consumes countless resources, but in the long run, it actually saves a lot of energy and greatly improves work efficiency, especially when Wharton is facing life and death, with these three giant towers, people on land can quickly go to space to assemble and organize battles, without having to fly up slowly in a landing craft.

As for the huge transport ship that Li Yi took when he implanted the memory and cognitive system in the coming-of-age ceremony, it actually used a magnetic energy engine and used the strong magnetic field of the planet itself, but this thing is still useful within 10 kilometers from the ground, once it is too far away from the planet, the magnetic field effect will be reduced, and it is impossible for the starship to fly out of the atmosphere by magnetic energy.

Li Yi also figured out the joints because he recently absorbed a lot of scientific and theoretical memory chips, the starships of this era are not the kind of omnipotent UFOs, each type or even the same kind of starships, their materials, engines, and structures may be a little different, for different purposes.

Even if it is a landing craft, in different planetary environments, due to the difference in gravity, climate, pressure, and atmospheric materials, it cannot be the same, like a landing craft that can land normally on the Wharton star from space, if it is thrown to Watson 13, the landing craft is estimated to be oxidized into a bunch of sulfate, water and hydrogen by the concentrated sulfuric acid layer in the atmosphere, and the human beings inside will be even more miserable, directly dehydrated and carbonized.

Therefore, although this trip to Althea Star is to introduce the Manning family's gas mine development technology and equipment for Althea Star, in fact, it can only be regarded as a reference and reference, and the same gas mining ship or equipment is completely different in different atmospheres.

Mining gas ore in Althea Star, its minerals are mainly hydrogen elements, due to its special physical and chemical properties, the entire mining ship is a giant hydrogen bomb, so the first requirement for the overall structure of the mining ship and the mine silo is to have good sealing, otherwise once leaked, the consequences are unimaginable, and if the sulfuric acid ore is developed on Planet Watson 13, the cargo hold does not need too high sealing conditions.

Another example is the compressed refrigeration environment, the mining ship and mine warehouse of Althea Star need a high-pressure environment to store liquid hydrogen, so that the collection and storage efficiency is higher, while on Li Yi's resource planet, there is no need for high-pressure storage, and the liquid that directly collects sulfuric acid rain is concentrated sulfuric acid.

As for the materials of mining ships and ore silos, the requirements for collecting hydrogen ore are also higher, although sulfuric acid has strong oxidation and strong corrosion, but it is not enough compared to hydrogen, hydrogen atoms have strong reducibility, at high temperatures except for rare gas elements, almost all elements can be combined with hydrogen to form compounds, its hydrogenation is more metamorphosed, and even hydrogen can be directly dissolved in titanium alloys.

In fact, according to Althea, at present, in the development of hydrogen mines in Althea Star, there is a newly developed mining ship that uses a special titanium alloy ship that can incorporate hydrogen.

This kind of mining ship does not need any compressed refrigerated ore silos, no seals, and no hydrogen ore collectors, except for the necessary power engine and core equipment, it is a huge titanium alloy ingot.

This thing is very easy to mine, and you can fly directly to the outer atmosphere of Althea and come back with hydrogen ore, and the hydrogen ore that can be carried in the body each time is about 3,000 times the volume of its titanium alloy!

This amount of ore is far more than the average gas mining ship, and more importantly, this kind of mining ship is like putting a dry sponge into a bucket and then immediately fishing it out to get a large amount of water, which is very convenient, simple and efficient!

Of course, the cost of this new type of mining ship is extremely expensive, not to mention the technology, the construction cost alone is already very perverted, a starship with an internal space all made of titanium alloy entities, the titanium alloy materials consumed are at least a thousand times that of ordinary mining ships, and the cost of a space carrier is several times higher, even if it is the powerful Manning family, it is currently only a small amount of production.

While Althea was explaining these gas mining techniques and methods, Li Yi was also secretly thinking.

Comparatively speaking, his resource planet is actually not as high as Orthea Star in terms of development technology requirements, and it can even be said to be much lower, and in terms of technology introduction, there is actually not much availability.

Hydrogen ore is hydrogen ore, sulfuric acid ore is sulfuric acid ore, the physical and chemical properties of the two are completely different, people can directly drive the titanium alloy ingot-like mining ship into it to absorb hydrogen ore, if you do this, go out is titanium alloy ingots, and come back is a bunch of sulfate, it is too funny!

However, correspondingly, the cost of the transformation of the mining ship will be much smaller, but Li Yi does not think that this is something to be thankful about, the cost is low and the efficiency is low, he would rather invent a mining ship with a very high cost but high efficiency, otherwise such a big planet can only be dug in the year of the monkey?

Therefore, in terms of the development technology of Watson 13, Li Yi said to Althea and the scientific research institute: "In the design and transformation of the mining ship of sulfuric acid ore, do not consider the cost, only pay attention to efficiency!" ”

If it weren't for the fact that he hadn't mastered all kinds of scientific research and technology related to mining, Li Yi would have done it himself, but unfortunately now he can only rely on the power of the natives, which also strengthened his determination to study in depth in the direction of scientific research, even if the threshold is very high at the beginning, it will waste brainpower, and it is difficult to achieve valuable results in a short period of time, he is also unswerving.

After all, indigenous people are indigenous, even if it is a small country like North Wharton in the human social circle, it still has extremely rich experience and technology in the development of various forms of ore bodies, and Alser Yadang has come up with a set of sulfuric acid ore development plans that are no less than metal hydrogen storage.

Merely...... This set of plans is just like what Li Yi requested, the efficiency is indeed high, but the cost is really outrageous, which is higher than the cost of getting a few titanium alloy ingot mining ships, which makes Li Yi, who was still rich just now, feel a burst of emptiness in his heart.
