"5 centimeters of expanded subspace?"

Lei Luo muttered a hint of undisguised disappointment.

Although the research of curvature space technology in the human academic community is only in the initial stage of ignorant exploration, and even in order to obtain the progress of relevant knowledge and promote the progress of civilization, it has to fight a decisive battle with the superhumans of the Pangula Heights, and send Lei Luo to the underground world to try to obtain relevant clues, but in Lei Luo's eyes, the 5 cm subspace expansion technology is really not worth mentioning.

Lei Luo initially thought that the so-called victory of the underground world was hidden in five centimeters of space, which referred to the solidification of the five-centimeter space-time rift mosaic technology.

After all, there is only 5 centimeters of subspace expansion technology, although the human academic community has not been able to master the relevant technology, but from the perspective of the academic community, whether it is the space box developed by the Aurora Middle Earth Holy See, or the air pavilion relics left over from ancient times, the volume has far exceeded 5 centimeters.

Therefore, this kind of technology does not seem to be uncommon in Lei Luo's opinion.

And the opposite.

If the mosaic technology of solidifying the five-centimeter space crack can be obtained, then there are too many things that the academic community can do, at least to communicate information across the starry land, which can be regarded as supported by basic technology.

"You seem disappointed?"

Observing the emotions that are keenly aware of Lei Luo.

"Sort of. ”

Relo admitted.

"Oh?"

Surprised, the observer said, "So, you human academia have mastered the advanced subspace development technology?, in this case, you already have the basic defense means against the super-temporal structure blasting power of the super-body people, so the purpose of coming here is to embed the space-time rift into the real world?" Unfortunately, even if the Sleeper hadn't died, as far as I knew, it hadn't been able to master this technology, and all it could do was temporarily maintain a shallow spatial rift ten centimeters in diameter, not embedded into the real world at all......"

Even if it is cured 10 cm crack, I don't know how many times stronger than the 0.001 cm crack in the academic world, saving many years of experimental accumulation process in the academic community!

Pity.

One step late, the Sleeper has become history with relevant knowledge.

A door to open the branches of the higher technology tree has been closed, and the academic community seems to have to rely on itself to develop relevant knowledge, and obtain qualitative changes through the accumulation of long experiments.

Lei Luo's words were regretful, and he couldn't help but feel heavy.

"Although the academic community has not mastered the more advanced subspace development technology, in the eyes of the academic community, compared with obtaining the subspace development technology, it is undoubtedly more precious to expand the space-time rift and embed it into the real world technology that can only expand the power of the real world's material privacy, and then human beings will not only be able to achieve ultra-long-distance instantaneous communication, but also try to carry out speed-driving flight in curvature space, and the speed of anti-gravity vehicles in curvature space, even if it is only the most shallow action, ignoring the resistance of air energy and dust impurities in the real world, will increase by more than 10 times in an instant, allowing us to easily cross the space constraints of this continent and peninsula。 ”

"Didn't master the more advanced subspace development technology!?"

Observers seem a little incredulous.

"Then how did you get that victory? If there is no curvature space-time barrier forged by subspace development technology, the super-body people can ignore the defense composed of material energy in the real world through the deep curvature space-time teleportation technology, and any so-called strong fortress in the real world is like a peeled orange in the deep curvature space, there is no secret to speak of, they only need to send a small bomb to the core of the temple, tower, gathering place, and war machine, and they will be easily destroyed!"

Speaking of which, Lei Luo seemed to realize that he seemed to have overlooked the importance of subspace development technology.

This technology is obviously not just about making a space box.

The most important reason why the anti-gravity Sky Metal Fortress was not destroyed by the Superhumans during the initial battle against Pangura was the Aerial Loft Relic left behind by Ancient Aurora, which was what this observer called the space-time barrier defense mechanism.

So it seems.

If the space-time rift solidification and mosaic technology is the spear for civilization to break through the shackles of geographical space, then the subspace development technology is a solid fortress for effective defense against the curvature of other civilizations.

Suddenly, a magnificent and terrifying scene of war appeared in Lei Luo's mind.

In order to prevent the intrusion of other unknown civilizations in the depths of the Dark Continent, those civilizations that have mastered the incomparably high curvature space-time technology will inevitably be covered with hundreds of millions of traps constructed by subtle subspace on the vast wind wall.

They exist like a dangerous landmine.

Once an uninvited guest rashly intrudes through the shallow curvature space, it will easily be cut into pieces by these subtle subspaces, and will be lost forever in the curvature space until it is silenced.

And the iron curtain built by the super-body people on the star curtain world, the star curtain blockade formed by the superbody, is likely to be an infinite extension of this technology!

"Be sure to get its subspace expansion technology at any cost!"

Lei Luo's mind was full of the scholar's instinctive thirst for knowledge, and he kept roaring.

Take a deep breath.

Lei Luo suppressed the turmoil in his heart, and said with a solemn expression: "If Your Excellency is willing to use the expansion of subspace technology in exchange, I can inform Your Excellency of the level 7 civilization technology mastered by the human academic world." ”

"You ......"

Lei Luo's words also set off turbulent waves in the other party's heart.

A strong curiosity also torments the dark creature called the Observer.

Suppressed silence.

Eventually, the two reached a contract.

The canary painted skin was driven away by these two cross-racial academic exchanges, and left the tower space aggrieved.

"I'm here. ”

As the canary peel left, a few meters in front of Lei Luo, a subspace mirror that was only 5 centimeters tall appeared.

It has no thickness, and no traces can be seen from the side.

Only from the slope or front, can you see a mirror tomb with a length and width of 5 cm.

An old silkworm, bent over, with a weak posture, lay quietly inside.

Frinkled skin, it was full of exhaustion, looking at Lei Luo from the inside.

"Observer?"

Lei Luo flew up, facing the mirror surface with no thickness, looking at the strange lifeform that had fallen into the shallow curvature of time and space like a wall shadow demon.

It seems to have abandoned the real-world body and become a purely spiritual life.

"Forgive me for being able to communicate with you in this form, in order to survive, I had to learn from those rebels, descended to the dimension, survived, became this devil form, and even had to give up the ability to move in the curvature space in order to affect the real world by plucking the strings in the curvature space, and now I can't even be regarded as a life, maybe it's just a residual consciousness of waiting, an unwilling obsession, who knows......"

Belch?

Lei Luo squinted his eyes and said nothing, thinking about the other party's words.

The observer said: "The study of curvature space technology in Zero Degree Space, just like the legend outside, did not originate from ourselves, but by chance, I became a solidarity with the sleeper. At that time, me and it were just two inconsequential little ones here, we kept trying to explore the more marginal underworld, that time we made up our minds, we had forgotten how far we flew, the surroundings became more and more silent, more and more dark, loneliness and fear tormented us, there were many times in between, we wanted to give up, but again and again we persevered, until a powerful mysterious force dragged us there. ”

"There?"

Lei Luo asked.

"It's the curvature space of your mouth. ”

The observer's answer reminded Lei Luo of his own curvature space-time experiment in the Windsor Laboratory, those mysterious exchanges with himself who had fallen into the shallow curvature space wall shadow demons.

With an awe-inspiring look, Lei Luo nodded.

Observing and continuing, "We were terrified, we had never encountered anything like this, we even thought we were going to die for a while, and then that powerful rebel army appeared, and told us a piece of history, the history of the sixth-level ancient god Mantuo Sahua who broke through the iron curtain blockade of this world at the expense of himself, and severely damaged the superhuman history. ”

The old silkworm's words revealed a hint of longing, fear, and solemnity.

Its blank eyes scanned Rarrow up and down.

"Tens of thousands of years ago, the Wall Shadow Demon at that time was the predecessor of our dark creatures, ruled by the demon gods, they were unwilling to become slaves of the war of faith between the demon gods, and were determined to explore another power, so as to get rid of the slavery of the gods, so they followed the legend of Mantuo Sahua, found the power of time and space, but at the last experimental juncture, they lost control, and all the high-level Wall Shadow Demons who participated in the experiment were stripped of their bodies in the real world, reduced to become wanderers in the curvature space, and could only obtain rare evolutionary energy by occasionally capturing some creatures in the real world, which was a drop in the bucket......”

This history coincides with Lei Luo's previous speculation!

The former Wallshadow Demon is likely to be the civilization changer of the ancient creatures of the Starshade Land, but unfortunately the civilization evolution failed and became the kind of monster that can only operate in the shallowest space.

So, the subspace exploration technology that this observer has acquired is derived from those curvature space creatures?

"So, the great leader of the Wall Shadow Demon proposed to us a plan to trade, exchanging real-world materials for stable subspace and space-time rifts, which are the mysteries of our space-time technology and the power to defeat the superhumans. ”

"And how do you communicate!"

Lei Luo was keenly aware of the key.

Because he also had a friendly exchange with the Wallshadow Demon.

However, in the case that the two sides cannot use spiritual communication in the curvature space, the exchange of information has become a barrier for the two sides to continue to communicate deeply, and the exchange of knowledge is impossible.

When the old silkworm heard this, he smiled but did not say anything.

It just looked at Lei Luo silently.

Obviously, the way the two sides communicate is the core technology of this dark creature.

Nodding, Relo knew it was his turn.
