Tower Defense Strategy

In the past two months, the octopus's energy has been mainly outside the game.

The physical training of the first group of players was completed, and the equipment was then put in place. Most of the team's equipment is single machine, only a few are two machines based on mirrored robots.

Several battle command posts led their team members to catch several waves of people who had hit the border, and then worked to increase the automatic defense mechanism at the border.

The existing automatic reaction mechanism on the border has zero lethality on armored units, and naturally it cannot stop the opponent's actions.

According to the AI ​​management method, the host cannot randomly deploy weapons with strong lethality, so this matter has to fall on the defense personnel.

The new turrets and drones deployed by the octopus and team members are not permanent facilities. Once the external threat assessment drops to a certain level, the additional defense mechanism has to be removed.

In short, it's not a big deal, it just takes more time every day.

The energy spent in the game is limited, and the development is step by step, filling the organization of the four divisions of the First Army.

The confrontation with the monster did not continue to escalate.

Octopus realized that the monsters encountered by the earth ball in the background world are directly related to the battle he experienced, and he did not consider the tenth level.

In addition, the distance between Green Mist and the base has been shortened by a hundred kilometers. The impact of the upgrade is unknown, and more preparations are needed.

On the other-dimensional side, it has gone through some repetitions. Finally, with the special environment of the lava plain, he paid a certain price to replace the two attacking second-level monsters and strengthen the foundation.

Didn't the other dimension dug the relics of the Xianjun Empire before, this society has also received an answer.

One was said to be an expedition ship and replied that "keep the signal launching and wait for rescue."

There seems to be a bit of misunderstanding inside, as if the different-dimensional outpost is used as a camp for survivors of the Xianjun Empire.

What will happen in the future will be more specific.

Speaking of which, if they can find the Xianjun Empire, their industrial system may be even smaller with Tuqiu Technology. It is much easier to analyze on the platform than Octopus to check the ancient complete sets of industrial data through the host.

The focus is still on the development of the background plot.

In terms of monsters, Octopus has provided scholars in the base with a list of recent monsters.

The most recent second-level monster is Lyrus, the weaker among the second-level monsters, waste isopod bugs, and it is expected that there will be nearly two weeks before the earth ball will encounter it.

Then it was dangerous. Behind Lyrus, it was when the octopus first encountered the vision.

Phantom vision is double invisibility, optical and thermodynamic invisibility, plus the large-scale visual error produced by the mirage. The latter will also affect the optical sighting method. Its monster-like skills of the ancient gods have a greater range than the soul absorbing of the star smash.

Behind the vision enters an indeterminate branch.

Octopus's battle records show that after playing the Vision, he started to work with the Starsmashed Lair to the west.

Since Tuqiu has not yet appeared in the monster lair, I don't know if this part will affect the plot direction over there.

After the nest branch node, the daily monsters invaded the second company of the big move, namely the electric light and the black sheep.

The scholars at the base told Octopus about the threat ranking given by Tuqiu, and Octopus also felt that if the black sheep was pronounced by a bunch of people, it might really kill the world.

Assuming that the broken star branch does not delay the main sequence time, there are still five months left before the ball is fully played, and it will soon reach the point of survival. That's it, they have to be able to solve the vision and electric light better, if there is a string of broken stars in the middle, the situation will only get worse.

However, the scientists in Tuqiu did work hard enough. Just yesterday, the scholars who borrowed the laboratory from the base suddenly showed him a concept map.

The octopus doesn't need to look closely, glances at the scale, and asks: "Electromagnetic orbital launcher?"

Track is a simple word, the established route, but depending on the specific circumstances, the meaning will be different.

For example, in the game, the difference between an electromagnetic gun and an electromagnetic railgun is that the latter only accelerates the track a little longer, resulting in a higher initial velocity of the projectile.

The orbit and the launcher are connected together, which is a specific term in the history of octopus.

The scholar did not understand it for the first time, and muttered and repeated: "Electromagnetic orbital launcher?"

Octopus found the problem and explained: "A device that assists in the launch of rockets, the purpose of which is to throw materials into orbit."

"Ah!? There really is this?"

Octopus nodded: "Of course, I want to save fuel for breaking through the atmosphere. Isn't this a natural route?"

"...Hey, there are still many people in the yard who say they are fantastic."

The octopus looked over with interest, and the scholar began to explain.

Country C has recently launched a large number of rockets, but not all of them have been successful. The aerospace system devotes its main energy to ensuring the safety of rockets for astronaut shifts. A certain failure rate has become an inevitable result of simplifying the process.

Every failure is the loss of hundreds of tons of fuel, rocket shells, and equipment, so distressed.

So some people who study electromagnetic topics mainly focused on 277 thought, we all have superconductors close to zero, can it be used to make a super-large electromagnetic device that gives a certain initial velocity to the rocket?

Rockets are not suitable for electromagnetic acceleration? Don't know how to add an accelerated eggshell?

Similar ideas also appear in some science fiction works, but those non-professionals always feel that they can hit an unmotivated thing directly from the surface to the track.

It can’t be said that there is no possibility. It can only be said that something made of the existing materials of the earth ball reaches a certain weight and size. Under such an acceleration, it will fall apart before it leaves the electromagnetic orbit. Of course, it is unnecessary. Continue to discuss how to make the launcher.

The idea proposed by the scientist is sufficiently feasible in itself.

The launch of a spacecraft is a process of adding more water to the surface and adding more water to the surface.

A rocket launched from the surface into the air consumes almost a third of the fuel before reaching the speed of sound. In order to bring this extra fuel to the sky, a heavier engine must be used. If the engine is heavier, it is necessary to bring more fuel to achieve the same speed.

In other words, if the rocket can be given supersonic speed on the surface, it can directly save about 40% of the rocket's weight!

In turn, the small rocket used for low-orbit replenishment was originally only over 200 tons. After saving 40%, is it possible for the remaining weight to reach supersonic speed through the electromagnetic orbit?

After some discussions, we have this conceptual picture in the hands of Octopus.

Scholars took it out to find out whether it is feasible from the "alien".

"According to the size you designed, the problem is not big." Octopus said half a sentence and looked at the scholar, "Do you want to listen to the classic electromagnetic orbital launch theory?"

"Wow, good."

The octopus was unambiguous and said directly: "It shoots at 2 to 2.5 times the speed of sound. The rocket maintains its speed and height in the first stage to avoid trouble caused by aerodynamic heating. The second stage is the same as a normal rocket launch."

During the rocket launch process, neither acceleration nor deceleration is a waste of fuel, but if the aerodynamic heating can be avoided at all times, the entire rocket does not need heat insulation except for the engine area. The lightest aluminum alloy can be directly mounted on the same. Can save part of the weight.

In short, when the rocket can obtain the initial speed from the electromagnetic orbit, it will be more famous, and the weight that can be saved is far more than the 40% that the earthball scientists envisioned.

In the history of octopus cognition, the application time span of the electromagnetic orbital launcher is very long, several times longer than that of the existing rocket history of Tuqiu. Before the appearance of the large-tonnage high-frequency space elevator, it has always been a transatmospheric transportation system. Main force.

After going through various stages of theoretical controversy, and finally gaining wide application, he outlined the system that broke through the dense atmosphere at 2 to 2.5 times the speed of sound. Its advantages include higher controllability throughout the process, reasonable load ratio, and limited energy loss against atmospheric drag. and many more. In all theoretical systems, it is not the highest in all aspects, but it has the highest comprehensive score. In short, it is easy to use!

With the quasi-credit here, country C moved again.

Rather than rushing to cooperate with the aliens, but according to the previous launch method, even with the national strength and strategic resource reserves of country C, it is still a bit unable to carry it. It is not at all whether it will be able to promote the space industry plan quickly and effectively in the future~ www.wuxiamtl.com~ Now that it has been confirmed that the electromagnetic orbit is the inevitable way to break through the atmosphere, please push it quickly.

Across the country... mainly to the south, looking for shafts with a depth of 300 to 600 meters.

In fact, there are many similar shafts. Most of them are left behind for the two-way construction needs of tunnels. Some tunnels have been used because of alternative routes and other reasons. The utilization rate is very low.

Having said that, there is little need for the expansion of alternative routes, because the current marine trade environment is simply not enough to support the vision of everyone having a car, and the number of motor vehicles is declining. What else is there to talk about broadening? There is no need for it. All.

Twenty shafts that meet the basic requirements were selected across the country, and then they waited for demonstrations, small experiments, and reconfirmation from the Academy of Sciences.

The basic plan was taken out, and finally three shafts were confirmed as the basis for the future reconstruction of electromagnetic orbital launchers.

These three shafts have a common point. Outside the tunnels connected by the shafts, there is a slope, and the nearest railway transportation line can be directly transferred to the place by road.
