Aurora asked a more practical question. "If, as you speculate, those gods are also beings of a higher dimension, then what?"
"That means most of our methods are probably incapable of harming the enemy!" Lin En said solemnly. "Let me give you an example, there is a flying enemy now, I only tell you that he is 15 meters away from you on the X axis and 35 meters on the Y axis, can you hit him?"
Aurora was stunned at first, then she immediately understood what Lin En meant. It was impossible to hit the enemy with only the horizontal and vertical coordinates, because there was a very critical factor missing - the vertical axis!
If you don't know how high the opponent is flying, of course you can't guarantee a hit, because he could be at any altitude.
Now they were facing the same situation. They were in three-dimensional space and only knew the coordinates of the horizontal, vertical and vertical axes, but they could not determine the other party's four-dimensional position at all...
"If we observe low-dimensional space from a higher dimension, it will be different. I'm afraid everything about us will not be a secret to the other party." Lin En said solemnly. "We can also compare the observation of two-dimensional space from three-dimensional space..."
Lynn stretched out his hand and tapped the table, using magic to construct several strange-looking two-dimensional people. They were as thin as paper, and their internal organs were displayed in front of everyone as if through perspective.
Lin En stretched out his right hand and slapped them hard, crushing them completely...
Harov's eyebrows jumped and he said in horror, "In this case, don't we have no chance of winning?"
Aurora, Vittorio and Anthony all looked grim. Being strong was not scary, but this time they had to face an opponent that was completely incomprehensible.
"That's not entirely true..." Lin En shook his head and continued, "It's not that we don't have the ability to influence higher-dimensional space."
Anthony, Aurora and Vittorio all looked at Lin En in surprise, very curious about what the ability he was talking about was.
Harov was the first to realize what was happening and spoke out.
"It's observation!"
Hearing this, the others immediately reacted, because it was through observation that they caused the microscopic particles to collapse from the state of probability cloud.
"That's right, but observation alone is not enough. What we see is mostly just the projection of the higher-dimensional world on the lower-dimensional world." Lin En explained.
In fact, in the previous life, many researchers in the Federation speculated that microscopic particles have certain high-dimensional characteristics, so they seem so unreasonable to them who only have three-dimensional perception, because they only see partial projections.
The magical phenomenon of quantum entanglement may also be a link in a higher dimension.
"So what we need is the same level of observation to know the other party's exact information!" Lin En said calmly.
"That means we have to wake up Artok as soon as possible." Vittorio said. Only the quantized Artok can fully observe the information of the higher-dimensional world.
But... it is not easy to wake up a crazy person, and they can't even guarantee that the other party will not attack them as well.
But no matter what, Artok's combat power is extremely important now.
Thinking of this, Harof and the others began to discuss what method should be used to wake each other up. The multi-person observation method proposed by Linn could be tried - the prerequisite is to solve the great wizards' fear of the strange manifestations of microscopic particles.
Aurora even had the wild idea of using the method of faith, because she felt that the reason why those gods would not appear in a situation like Artok was probably related to the huge number of believers.
Lin En nodded. In fact, with the help of the magic network, he could barely observe scenes in higher dimensions.
This was partly because of the surge in computing power, which gave him the possibility to understand four-dimensional space, and partly because of the intelligent brain! When he traveled through, the intelligent brain was quantized for unknown reasons. It was like a window from low dimension to high dimension. As long as the computing power was sufficient, it could support him to explore the scene of the high-dimensional world.
In the terms of magic, it means that one who possesses the divine nature can barely touch the realm of God!
"Also, you don't have to worry too much. Artok's quantum probability cloud is limited to the scope of the domain. I guess the power of those gods can only be truly manifested within the divine domain. This means that we don't need to face a high-dimensional existence in a period of total victory."
Lin En said soothingly, boosting everyone's confidence.
Perhaps this is why the crow repeatedly reminded them to let the Lord of the Dead come into this world.
"Yes, God is not invincible, otherwise the Moon Goddess Diana would not have fallen!" Harof nodded, and Aurora and Anthony's faces also looked better.
Vittorio told them a piece of bad news. According to their latest report, the undead army from the foreign land had become agitated and was frantically searching for the location of the time and space node. It was very likely that they had already determined the approximate direction.
"It looks like war is coming..." Aurora raised her eyebrows, her tone very calm.
Lin En and the others were not surprised. Thanks to the warning from the Star Messenger, they had anticipated that such a day would come and had been preparing for it.
In fact, it was beyond their expectations that the war could be delayed until now. According to the worst prediction, the war would break out within three months, and now it has been nine months! The large-scale construction plan formulated by the parliament has been completed for the most part, especially the laying of magic base stations has covered 36 important cities in the empire, and the magic network should be able to operate within the empire.
"Did Raphael say anything else?" Lynn continued to ask.
"They said they would delay it as long as possible and divert the attention of the undead to other places." Vittorio sighed.
The danger of doing this can be imagined. The halfling settlement where Raphael and others were located was not far from the valley where the space-time gate was located. If they found something wrong, they could retreat at any time.
If we lure the enemy to other places now, it will be difficult to come back.
Aurora also felt that Raphael's move was very risky, but she couldn't say anything against it, because the difference in the speed of time between the two places was almost their biggest weapon. If they could prepare for one more day, their chances of winning would increase! "According to Raphael's own estimate, they can at least delay for half a month, and maybe a month if they are lucky," Vittorio added.
Previously, the parliament did not know that the enemy would attack from that space-time gate, so they arranged defensive forces in almost every location. Even if airships and trains could be used, it would take a lot of time to assemble them. Three and a half months was not enough!
"If they successfully delay enough time, do we need to organize a rescue?" Anthony suddenly asked.
As soon as these words were spoken, the people present fell silent. If Raphael's plan succeeded, it would mean that the other party would attract the attention of most of the undead, and the situation would become extremely dangerous.
"Save!" Lynn said without hesitation.
Harof couldn't help but frown. Saving nature was the most morale-boosting approach, but it was also the most irrational. After all, the risks and costs were too great.
It is very likely that several of their speakers will need to work together to rescue the other party, or even send troops directly into the space-time gate.
If the Lord of the Undead has already taken control of the alien realm, they will not even have the ability to resist the higher-dimensional existence.
If a large number of elite soldiers fall in a foreign land, then this world will be doomed! Without waiting for the others to object, Lin En continued to explain. "In fact, there is no need to dispatch too many people. It is enough to send an airship and a fighter plane. One to open the way and one to transport people!"
"Are you sure?" Aurora looked at Lin En in great surprise.
The latest chapter of this novel was first released on 6@9shu#bar. Please go to 69shu#bar to read it!
According to his understanding, the speed of the fighter plane can reach about three to four hundred kilometers per hour, which is indeed very fast, but only for ordinary opponents. It is not enough in front of the legend.
"Recently, Master Dennis has developed a new type of propulsion that can greatly increase the flight speed of fighter jets." Lynn continued.
"How fast can it be?" Harov asked with a smile. In his opinion, it was nothing more than an increase from 300 kilometers to 500 or 600 kilometers. This was indeed fast, but still not good enough.
"If nothing goes wrong, it should be able to reach about three times the speed of sound!" Lin En said with certainty.
Of course, the speed of sound in the two worlds is different. According to Raphael's calculations, the speed of sound propagation in the alien world is about 280 meters per second, which means that in the alien world, it is likely to reach 3.5 times the speed of sound! "Three times... the speed of sound?!" Harov almost doubted whether he had heard it wrong. Even if he flew at full speed, it seemed to be only about 1.5 times the speed of sound.
Anthony, Aurora and Vittorio were equally astonished. Doesn't that mean that even they can't catch up with the fighter plane when it's flying at high speed?
Most importantly, they considered moving at the speed of sound to be one of the criteria for entering the legendary realm. How could a mere alchemical creation reach such a fast speed?
"Are you really that surprised? My electromagnetic railgun can even reach over 30 speeds of sound, not to mention the speed of light."
Lin En said with a smile that the aircraft he saw in the database of the intelligent computer, even the slowest one, was calculated at several times the first cosmic speed. These old spacecraft that were incapable of interstellar travel could only be used as transportation within the galaxy, so exceeding the speed of sound was never a big deal in Lin En's view.
Listening to Lin En's words, Harof and others were speechless. Breaking the speed of sound with some magic and flying by oneself are two different concepts.
After experiencing the power of legends, several people vaguely had the idea that everyone below the level of legends was an ant. Now this concept was undoubtedly shattered by a fighter plane.
Combined with the Eternal Flame or even a small fusion bomb, a skilled pilot could pose a considerable threat to them.
Everyone present was trustworthy, and Lynn did not hide the principles of the new fighter plane. He focused on introducing Dennis' explosive thrusters.
It's called an explosion, but it actually uses the principle of rapid expansion of highly compressed gas after combustion, and then uses the Laval tube to accelerate the ejected high-speed airflow twice, thereby generating a powerful thrust and breaking the sound barrier...
"This is just like the principle of muskets and cannons..." Vittorio's eyes suddenly lit up, and he immediately suggested that after the supersonic production test flight was completed, he must make an exception and award Dennis a Silver Moon Medal. He was absolutely a genius in alchemy to be able to think of this kind of propulsion method.
"That transonic nozzle is very interesting. I wonder if we can also fly in this way." Aurora was very interested in this unique gas-propelled flight.
"If you have time, you can study it." Lin En had no intention of getting involved. Recently, he was studying how to increase speed by distorting space like Ella did in the past, so he had no time to think about this inefficient way of speeding up.
If they can decipher it, they may be able to make an extremely terrifying propulsion device, that is, the curvature engine!
Since before he traveled through time, the Federation had been thinking about this new method of propulsion and had even designed the blueprints, but the problem was that they couldn't find a truly stable and controllable source of gravity, so it had been shelved.
But with the power of magic, they seem to have a chance to overtake others...
"Since Dennis has produced a new fighter plane, the rescue operation can indeed be tried." With just one sentence, Harov brought the gradually distorted topic back on track.
"There is only one thing we need to consider, which is how to rescue?"
By then, Raphael and others will inevitably be surrounded by a large number of undead, among whom there may be legendary beings. It is impossible to rescue them with a single fighter plane no matter how fast it is.
"I left a backup plan on the ring I gave to Master Raphael. Together with the nuclear warhead given to him by Speaker Vittorio, it should be enough to deal with most situations!" Lin En said solemnly. He had tried it when he sent people back four times. That thing should be able to work in a foreign land.
"Since you have a plan, let's do it!" Harrov nodded. Anthony, Aurora and Vittorio had no objections. If there was a chance to save someone without taking too much risk, they would naturally give it a try. Otherwise, it would be too disheartening.
"As for the time of action..." Lin En paused. "Let's set it in three and a half months!"
That is, half a month after arriving in the foreign land. This was the shortest deadline that Raphael thought he could obtain. If they died before that, the parliament would be powerless to do anything.
