The previous information about the Fengchuan Hall was basically learned by torturing Fu Bei's soul, and the relevant memories were imaged with magic, so Xu Xianxian knew very well about the layout and structure of the hall, the things inside, and the passage of the labyrinth.

But knowing that she still underestimated the defense mechanism of the energy hall, even if she remained illusory, to the point that the instrument could not scan and recognize, it was still considered an unknown object, and then it was directly dragged in by the defense matrix to suppress and bind.

"This defense mechanism seems to be very intelligent, but in fact it also has a rigid side, that is, no matter what foreign object is found, it will be solved directly with the defense matrix. Xu Xianxian wandered in the lake of energy, and the corners of her mouth spit out the bubbles of 'coo' on the side of her mouth: "But this is different from the defense system I knew before, it is just a tough defense matrix devouring, but there are no machine guards to clean up and suppress anything." "The previous alarm device, but it couldn't scan and identify her, and then it automatically opened the defense matrix, and it didn't alarm any defense level, and it didn't send a corresponding mechanism to clean it up.

Not even the intelligent machinery in the temple appeared.

This situation is very different from what Xu Xianxian learned from Fu Bei.

She pondered for a moment, but she didn't come up with a reason, so she could only take one step at a time, resisting the powerful corrosive force brought by the defense matrix, and swimming deeper with the breath left behind by the nightmare.

The deeper you swim, the higher the temperature around you, gradually rising from tens to hundreds of degrees, and the corrosion of the matrix intensifies.

Before being dragged into the defense matrix, Xu Xianxian thought that this was something similar to a magic array, but in fact, this high-tech product was fundamentally different from the magic system she mastered.

This defense matrix is said to be a large array, but in fact, the core is this endless energy lake, and the energy structure here is very peculiar.

Xu Xianxian was able to analyze the microcosm with the eyes of the fairy, so the energy bodies projected in her pupils were composed of countless tiny triangular particles.

These tiny triangular particles are connected by a strange miniature circuit to form a larger triangular energy particles, and the entire lake overflowing with energy is composed of such triangular energy particles. Under the established operating rules, these triangular energy particles formed an extremely large defense matrix, which was controlled by a core position in the main hall.

As she swam down the energy lake, she tried to disassemble the energy particles in order to understand the laws of these special energies and the basic rules for building a defense matrix.

"Hmm... Among these energy particles, some of them are similar to the ancient dragon vein power, which is a remnant of the laws of the Heavenly Dao, but the nature has changed. ”

In the absence of magic tools and instruments, Xu Xianxian could only conduct a preliminary analysis, and then could not continue.

However, Rao still got the general information from it.

The operation law between energy particles is a bit similar to the dragon vein that was absorbed before, but the level and essence are much lower than the dragon vein.

If the dragon vein is part of the rules of the concretization of the Heavenly Dao (Star Soul), then the energy lake here is a trace of the breath left by the Heavenly Dao in the world.

The roots may be the same, but the nature is different.

"It's no wonder... With such a large range of energy lakes, if it is really the embodiment of the rules of the Heavenly Dao, with the favor of the Mandate of Heaven, Luo Gong City may have already become the first strong city, not to mention the unification of the earth, it is absolutely no problem to conquer this continent. ”

For this information, Xu Xianxian's eyes showed a little disappointment, but it was expected.

She had absorbed some of the Black Dragon Veins left over from ancient times before, so she was naturally able to understand the difference between the Heavenly Mandate Dragon Vein and this energy lake.

"Judging from the current earth, there is a big problem with the Heavenly Dao (Star Soul) itself, otherwise even the gods would not be able to hunt so easily. ”

Xu Xianxian glanced at the deeper part of the lake, where it was all pitch black, and there was a faint extremely high heat, and he instantly understood that under this energy lake, it was close to the core of the earth.

The earth is just a planet, and it can't shine and heat on its own, so the temperature is far less than that of stars, but the temperature of the earth's core reaches more than 6,000 degrees Celsius.

Now that Xu Xianxian is just approaching the periphery of the earth's core, she can feel the surrounding temperature, which has reached more than 2,000 degrees, but this temperature is still within her tolerance range.

After all, before killing Meng Ge, the temperature of the forbidden spell meteor she used was as high as hundreds of thousands of degrees, almost one percent of the central temperature of the general nuclear bomb explosion, but this was when the rules of the world weakened most of the time, and she could only summon similar small stones, not real extraterrestrial meteorites.

The magic forbidden spell of the demigods is more powerful than the limit of the material world, and beyond the imagination of ordinary creatures and civilizations, so no matter what, they can only show a very small part.

Of course, the current Xu Xianxian is not a demigod, but the high temperature of several thousand degrees still can't hurt her, a goblin like her is no longer a simple flesh and blood body, as long as she is willing, not only can she not be caught with the naked eye, even if it is an ordinary tangible substance, it is difficult to touch her.

Just like no matter how high the temperature of the sun is, it can't burn through the dimensional space, and it can't touch a single hair of her. Only a powerful creature of the same level, using the power of the same level, could pull her out of this state of nothingness.

It's like a brilliant calculator that can easily perform mathematical calculations, but it will never be able to calculate a complete, written philosophical work.

If you are not in the same area, you are not at all within the framework of a dialogue.

And the reason why this defense matrix is a threat to Xu Xianxian is precisely because the two are within the same domain framework, and the high temperature cannot hurt her, but this energy lake with the breath of heaven has the possibility of threatening her.

"If this defense matrix had an autonomous will, I might really have to capsize in the gutter, but fortunately, this thing seems to be controlled by humans, at least by intelligent machinery, and there is still an essential difference after all. ”

Weapons have autonomous intelligence, and those who use weapons have intelligence, but that's two different things.

Xu Xianxian went downstream, ignoring the drastic changes in the temperature around her, and then stopped near the earth's core, she looked at the bottom layer of special alloy isolation zone, leaned over and touched it, and slapped it twice.

Although the distance was still a little far away, Xu Xianxian could already vaguely sense that in the deepest part of the earth's core, there was a powerful soul sleeping.

"My guess is indeed correct, this energy lake, and even the entire Fengchuan Hall, is extracting the breath leaked from the Heavenly Dao (Star Soul) and using it as a special energy source. ”

But this discovery, both expected and unexpected, was a very contradictory feeling, but it was.

Because Xu Xianxian couldn't imagine that the human beings on the earth could establish an energy hall one or two hundred years ago to extract the breath of the Heavenly Dao (Star Soul) and use the Heavenly Dao (Star Soul) as their inexhaustible new energy?

How did the human technology tree come up in the first place, and why was it possible to break through the inherent bottlenecks and shackles of civilization in leaps and bounds?

What's going on here?

The mystery in Xu Xianxian's heart has not increased but decreased, and he always feels that everything before the destruction war is covered with a layer of historical fog.
