Previous information about Fengchuan Hall was basically obtained through interrogating Fu Bei's soul, and the relevant memories were imaged using magic. Therefore, Xu Xianxian was very familiar with the internal layout and structure of the hall, the things inside, and the passages in the maze.

But even though she understood it, she still underestimated the defense mechanism of the Energy Hall. Even if she maintained her intangible body to the point where the instruments could not scan or recognize her, she was still considered an unidentified object and was directly dragged in by the defense matrix for suppression and restraint.

"This defense mechanism seems intelligent, but it's actually quite rigid. No matter what foreign object it finds, it's simply destroyed by the defense matrix." Xu Xianxian drifted through the energy lake, gurgling. "But this is different from the defense systems I've known before. It simply devours everything with the matrix, without any mechanical guards appearing to clean it up or suppress it."

The previous alarm device simply failed to scan and identify her, and then automatically activated the defense matrix without alerting any defense level, nor did it send out the corresponding mechanism to clean up.

Even the intelligent machines in the temple did not appear.

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

She thought carefully for a moment, but couldn't figure out the reason. She could only take one step at a time, resisting the powerful corrosive force brought by the defense matrix, and swimming deeper following the breath left by the nightmare.

The deeper you swim, the higher the surrounding temperature becomes, gradually rising from tens of degrees to hundreds of degrees, and the corrosion of the matrix also increases.

Before being dragged into the defense matrix, Xu Xianxian thought it was something similar to a magic circle, 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 formation, but in fact its core is this endless energy lake, and the energy structure here is very peculiar.

Xu Xianxian can use the fairy eyes to analyze the microscopic world, so the energy bodies projected in her pupils are composed of countless tiny triangular particles.

These tiny triangular particles are connected by unique microcircuits to form larger triangular energy particles. The entire lake overflowing with energy is composed entirely of these triangular energy particles. These triangular energy particles operate under established rules, forming an extremely large defense matrix, controlled by a core location within the hall.

As she swam downwards in the energy lake, she tried to disassemble the energy particles in order to understand the operating principles of these special energies and the basic rules for constructing a defense matrix.

"Hmm...some of these energy particles are similar to the power of ancient dragon veins. They are the remnants of the laws of heaven, but their nature has changed."

Without magical tools and instruments, Xu Xianxian could only conduct a preliminary analysis and could not proceed.

But even so, she still got some general information from it.

The operation rules between energy particles are somewhat similar to the dragon veins absorbed before, but in terms of level and essence, they are much lower than the dragon veins.

If the dragon veins are part of the concrete rules of the Heavenly Dao (Star Soul), then the energy lake here is a trace of the Heavenly Dao left in the human world.

The root cause may be the same, but the nature is very different.

"It's no wonder... If such a large energy lake were truly the embodiment of the laws of Heaven, and if it were favored by Heaven, Luogong City would have long been the most fortified city. Not to mention unifying the Earth, conquering this continent would have been a piece of cake."

Xu Xianxian showed a bit of disappointment at this information, but it was also within her expectations.

She had previously absorbed a portion of the ancient black dragon vein, so she naturally understood the difference between the destiny dragon vein and this energy lake.

"Judging from the current state of Earth, there must be something seriously wrong with the Heavenly Dao (Star Soul) itself. Otherwise, even the gods wouldn't be able to hunt so easily."

Xu Xianxian glanced deeper under the lake. It was all pitch black there, with a faint sense of extremely high heat. She instantly realized that under this energy lake was a location close to the earth's core.

The earth is just a planet and cannot emit light or heat on its own, so its temperature is far lower than that of a star, but the highest temperature at the earth's core reaches more than 6,000 degrees Celsius.

Now Xu Xianxian has just approached the outer edge of the earth's core, and she can feel the surrounding temperature, which has reached about 2000 degrees. However, this temperature is still within her tolerance range.

After all, before she killed Mengge, the forbidden meteor she used had a temperature of hundreds of thousands of degrees at the center of the explosion, which was about one percent of the temperature at the center of a normal nuclear bomb explosion. However, this was when the world rules were weakened for the most part, so she could only summon similar small stones, not real extraterrestrial meteorites.

The power of the demigod's forbidden magic spells exceeds the limits of the material world and is beyond the imagination of ordinary creatures and civilizations, so no matter what, only a very small part of it can be manifested.

Of course, Xu Xianxian is not a demigod yet, but the high temperature of thousands of degrees cannot hurt her. A fairy like her is no longer a simple flesh and blood body. As long as she wants, not only can she not be captured by the naked eye, but even ordinary tangible objects will find it difficult to touch her.

Just as the sun, no matter how hot it was, couldn't burn through the dimensions of space, nor could it touch a single hair on her head. Only a powerful being of the same level, wielding power of the same level, could pull her out of this state of nothingness.
