At the beginning, when building the castle, Chu Tianjiang made a special plan and built a cellar in the basement of the castle that was not too big.

According to Chu Tianjiang's vision, this cellar was mainly used to store some valuables.

Of course, there is also a more important role, which is to connect an underground passage to the outside of the river valley, which can be used for escape if necessary.

Except for Nicol and others, who participated in the construction of the castle together, only Clara knew about this cellar.

Entering the basement of the castle, Chu Tianjiang quickly found the cellar.

Finding the panel to enter the cellar, Chu Tianjiang had hope again.

That is, in this subspace, it is clearly not necessary to build this cellar, since there is simply no reason to dig an underground passage for escape. What's more, the panels of the cellar are made of manya steel and have not been moved, that is, they have not been discovered by others.

There was a palm mark on the panel, and Chu Tianjiang put his hand on it.

The size is just right, without a slight deviation.

After Chu Tianjiang exerted a little force, the panel shook slightly, then made a clicking sound, sank a little and then slid to the side.

The cellar did exist, and only Chu Tianjiang could open it.

Obviously, that palm print was designed for Chu Tianjiang. The size of the palm print is completely consistent with Chu Tianjiang's hand, and it must be Clara's masterpiece.

Underneath the panel was a passage that sloped down to the bottom, and after Chu Tianjiang entered, light appeared.

The light coming from the joint between the wall and the ceiling, blue, is very soft, has no temperature, and should be the light from a cold light source.

It's just that the furnishings inside the cellar are completely different from what Chu Tianjiang imagined.

There are no valuables, no escape to the outside world, there is a bed, a wardrobe. From the furnishings, it looks like a bedroom.

How so?

Chu Tianjiang was puzzled, because Clara and Natasha had no reason to convert the cellar into a bedroom.

There's definitely something wrong with that!

Chu Tianjiang searched carefully, but found nothing suspicious. The bed, wardrobe, dresser, etc., except that the main structure is made of manya steel, is nothing more ordinary, and the sheets are so old that they turn into pieces when touched.

Just when Chu Tianjiang was puzzled, he noticed the fitting mirror next to the wardrobe.

Clara is beautiful and loves beauty, even if Natasha doesn't look like an average girl, she is also beautiful, so in Clara's room, there is always a big fitting mirror. There was nothing special about this mirror, but Chu Tianjiang felt that this was the only place where there might be a problem.

It's just that it was indeed a mirror, and there was nothing on it.

Nothing was discovered, which made Chu Tianjiang a little discouraged and made him hateful. However, after he smashed the fitting mirror with a chair, he still found nothing.

It was indeed a mirror, but it was made of passivated glass, and when shattered, it produced some pieces without edges and corners.

At this moment, Chu Tianjiang was desperate.

It's just that when Chu Tianjiang squatted down against the wall, a strange thing happened.

The wall seemed to have disappeared suddenly, and the amount of force supporting Chu Tianjiang suddenly disappeared, and then Chu Tianjiang fell backwards to the ground.

Not on the ground, but in a completely empty space.

Chu Tianjiang was startled, and immediately got up, finding himself hanging in the air, standing on a transparent, completely pitch-black floor to be exact.

In the distance, there was some light.

Subspace within a subspace!?

Chu Tianjiang suddenly understood.

It's definitely a subspace built into a subspace, and it's clearly designed to protect something extremely important.

What's more, there is nothing in this subspace, except for the point of light, which is just a space.

Chu Tianjiang didn't hesitate, and immediately ran towards the light source.

Not a light source, but one, no, two glowing objects, two hibernation pods!

The hibernation pod floats in the air, and the light emanates from the control panel, which is actually a palm print like the one on a cellar panel. The two hibernation pods are identical, with only one difference, the one on the left has a torch mark on it, and the one on the right has a blood-dripping dagger on it. Although it was the first time he had seen these two marks, Chu Tianjiang had already learned from Iskar that the torch was the article of the Empress of Wisdom, and the Dagger of Blood was the article of the Immortal Empress, and the two articles showed the responsibilities of the two in the Shadow Empire, and they also happened to match their personalities.

Chu Tianjiang put his palm on the hibernation cabin on the right side, and the panel immediately emitted an even more dazzling light.

The panel does not open, but fades away.

When he came into contact, Chu Tianjiang found that the hibernation cabin was not made of matter, but an energy body, but it just looked like matter.

Then, Chu Tianjiang put his hand on the hibernation cabin on the left side.

The light emitted became brighter and brighter, making Chu Tianjiang unable to open his eyes.

Entering this subspace, Chu Tianjiang realized that the Shadow Empire had achieved more in science and technology than they had learned before.

The reason is very simple, the Shadow Empire can actually build a subspace within a subspace.

Although Chu Tianjiang is not a scientist, according to his understanding, this is a very remarkable technique, and it can even be said to be the highest achievement of human civilization in the field of space. Compared to the underground human civilizations, the Shadow Empire has achieved several levels of technological achievements.

It was precisely in this way that Chu Tianjiang considered a problem that he had ignored before.

That is, have Clara and Natasha been energized?

It is important to know that the Shadow Empire developed a large number of methods for producing energy bodies more than 1,500 years ago, and Clara and Natasha also "disappeared" at this time. Although according to the rumors of the Shadow Alliance, the two empresses did not disappear, but went to a mysterious place, waiting for the arrival of the savior, Chu Tianjiang preferred to believe that after Clara and Natasha mastered the technique of creating energy bodies, they first realized energy, and then built subspace, or both. The main purpose of the energy, in addition to gaining more powerful abilities, is also related to Chu Tianjiang, that is, they firmly believe that Chu Tianjiang is back, and he returns to them in the most powerful form. Because Chu Tianjiang was the first person to be fully energized, they could only assist him after they achieved energization.

Now, the problem arises.

How thorough is Clara and Natasha's energization?

If it is completely energized, then as long as they can obtain the energy body, they will have an infinite lifespan and do not need to hibernate at all.

On the contrary, if it is not completely energized, unless Clara undergoes a transformation, there is no infinite lifespan.

Also, how much change will radical quantification bring to them?

Although Chu Tianjiang knew that true energy people possessed abilities that far surpassed those of mutants, that was more than 10,000 years ago. For intruders who have fully mastered space technology and whose scientific and technological strength is several grades higher than that of humans, energy is nothing at all. What's more, quantification is the way for humans to achieve self-evolution, so it is very likely that the invaders will regard the energized person as a mortal enemy.

Thinking of this, Chu Tianjiang's mood became even more complicated.

Clara and Natasha worked hard to create this double subspace, which just proved Chu Tianjiang's guess that they had achieved energy and become real energy people. Perhaps this is why the Shadow Empire has been destroyed, and they have long realized this, so they have built a double subspace to hide from the invaders. Thinking deeper, the invaders did not immediately cut off the Shadow Alliance, but let the church launch an attack every once in a while, perhaps hoping that through the Shadow Alliance, they would find the hiding place of Clara and Natasha and eliminate the two most threatening enemies. Only before that, no one noticed this double subspace.

Regardless, Clara and Natasha are still alive.

Chu Tianjiang sighed secretly, although the situation was not optimistic at all, as long as they were alive, all difficulties could be solved.

The dazzling light dissipated, and it took a long time for Chu Tianjiang to open his eyes.

It was pitch black, there was nothing, not even an exit to be found.

Chu Tianjiang was taken aback, because this was a subspace without any decoration, so there were no iconic objects, not even light. Even if the entry point of this subspace is not closed, Chu Tianjiang may not be able to find it, and he may not be able to leave.

Thinking of this, Chu Tianjiang was even more worried.

It can't be a trap, right?

If Clara and Natasha had died long ago, and if the invaders had already controlled the entire Anthropocene, then the invaders were more than capable of creating a trap, and even the people on the farm, as well as Iska, and everything they encountered along the way, were created by the invaders. The ultimate goal of the invaders is to kill Chu Tianjiang and this person who has a four-dimensional cosmic space and a great civilization that exists in the Dao of Knowledge.

Perhaps, the intruder could not completely destroy Chu Tianjiang's consciousness, after all, the existence of the great civilization made it possible for Chu Tianjiang's consciousness to leave the body at any time and enter a space where the invader could not find or exert his strength, so the only way for the invader was to imprison Chu Tianjiang's consciousness.

A subspace isolated from the outside world is obviously ideal.

What's more, Chu Tianjiang entered this subspace unsuspectingly, and his existence was not known to the outside world at all.

What to do?

Chu Tianjiang felt a cold sweat break out on his body. This is not a joke, being locked up here, he can't die if he wants to, and there is no way to escape if he wants to.

"Are you scared!?"

A voice that suddenly came out did not frighten Chu Tianjiang, but made him breathe a sigh of relief, because it was a voice that made him unfamiliar with it.
