It is obviously impossible to find the other six tokens.

What to do?

"Where's the entry point?" Chu Tianjiang didn't want to look back, and he didn't want to spend more time looking for clues. If the "Holy Mountain" was the masterpiece of Clara and Natasha, they would definitely leave another way to open it, one that only Chu Tianjiang could open.

"Right in front of you, about half a meter."

There was nothing in front of him, and Chu Tianjiang turned his head to look at the figure.

"An innocent two-dimensional flat space with no thickness. If it is not opened, the entry point will not cause any damage and will not be detected. ”

"How did you find out?"

"The probe particles that I released went out of control after passing through the plane where the entry point was, and the quantum communication correlation was disconnected."

"This ......"

"A product of spatial distortion."

"Spatial distortion!?"

The figure nodded and said, "The so-called 'subspace' is not created, but compresses the existing space to a certain point, a certain line or a certain surface, which will also lead to spatial distortion. It may seem hard to understand, but it's actually the same as when we crumple a piece of paper into a ball and fold it into a strip of paper. As long as we have the relevant methods, we can isolate parts of the space in this way. ”

Although the figure didn't say much, Chu Tianjiang knew that the subspace he came out of before was also made in this way.

The difference between the two subspaces is that the entry point of this subspace is a plane, so that living people can enter. Because the entry point of the subspace where Chu Tianjiang was located before was a point, after leaving, the personnel could not be allowed to enter.

"What now?"

"You can give it a try."

Chu Tianjiang nodded and let the figure continue.

"Either way, Clara and Natasha are sure to believe that you will come back, and you don't know how to open and enter the subspace, so you will definitely leave a way to open it specifically for you."

Chu Tianjiang didn't say anything and walked up directly.

"Wait......"

Before the figure could finish speaking, Chu Tianjiang had already walked up and stretched out his hand.

What happened next also startled Chu Tianjiang. After coming into contact with that invisible entry point, Chu Tianjiang felt blocked by something. As soon as he exerted his force, his hand disappeared from the air, entering the subspace through the entry point to be precise.

Obviously, Chu Tianjiang's personal information can open the entry point.

"It's that simple!?" Chu Tianjiang was very surprised.

"You should be a little more careful." The figure shook his head and said, "It's too reckless to do that, if our guess isn't accurate, you're ...... now"

Iskar walked over, looked at Chu Tianjiang in amazement, and then stretched out his hand.

Although the entry point was a plane, and a large plane, Iskar did not pass through, or nothing happened.

Obviously, only Chu Tianjiang was able to enter the subspace.

"Iska, you're waiting for me here."

Iskar bit her lip and nodded. She no longer doubted Chu Tianjiang, and knew that Chu Tianjiang was the savior in the prophecy.

Chu Tianjiang took a step forward and entered the subspace.

It's just that the only thing that can enter is his body, and everything else, including the clothes on his body, is all cut into the subspace.

Inside was a river valley, the river valley home that Chu Tianjiang was too familiar with.

There are castles, farmland, waterwheels, fish ponds, a leveled threshing floor on the river beach, and pipes that lead to the hot springs from afar.

All this is no different from the river valley homeland that Chu Tianjiang expected.

Could it be that Clara and Natasha have used subspace techniques to preserve their river valley home?

No way!

The figure made it abundantly clear that in the great geological changes before the catastrophic era, the valley home was completely destroyed and buried underground with the earthquake.

Apparently, Clara and Natasha built their valley home here after mastering the subspace technique.

Chu Tianjiang closed his eyes and took a deep breath.

Chu Tianjiang was not surprised by all this.

On the way here, Iskar mentions that the sacred mountain is a paradise, a paradise where people can escape disasters and survive peacefully. Although he didn't expect it at the time, but seeing all this in front of him, Chu Tianjiang suddenly understood that Iska was talking about the river valley homeland. In fact, when she first saw the Vale Homestead, Clara thought it was a paradise.

Although Chu Tianjiang didn't know Clara when he created the River Valley Homestead, Chu Tianjiang knew that Clara cared about the River Valley Home the most.

Walking on the field road, Chu Tianjiang thought back to the past.

After joining this family, Clara has made a lot of contributions. If there is no difference, she may even become the head of the family. Although Nicol and the others have a higher status, they are not good at housekeeping, and none of them have the heart to be a housekeeper. The only one who can manage this home well and keep it running in an orderly manner is Clara. In addition, Clara maintains a good relationship with all of them.

Is she still alive?

Chu Tianjiang quickened his pace and walked towards the castle.

Luo Jinyong had already proved that subspace could protect the people inside from intruders, and he created the first subspace for this purpose. Because there are some survivors of the underground human civilization, and these people are likely to bring Luo Jinyong's discovery to the Shadow Empire. Even if there were no scientists like Luo Jinyong, Clara and Natasha could use more time to create new subspaces.

Chu Tianjiang suddenly thought that it was precisely because of the breakthrough in the subspace technique that Clara and Natasha disappeared, and then the Shadow Empire suffered a devastating blow. To put it bluntly, the most intolerable thing for intruders is for humans to master space technology. Even if the creation of subspace is only the most basic space technique, there is still a long way to go before it is fully mastered by space technology, just as it is as long as human beings learn to use fire and then develop nuclear weapons. The problem is that as long as human beings have mastered the technique of creating subspace, sooner or later they will be able to fully master the technique of space. It is precisely because of this that the underground human civilization has been wiped out, and the Shadow Empire has followed in its footsteps.

Immediately, Chu Tianjiang thought of a more critical question.

That is, the entry point of this subspace is a plane, not a point.

The biggest difference is that if the entry point is a point without scale, then only energy can pass through, not any matter can pass through, because it is impossible for any matter to be broken down into points without dimensions, even elementary particles cannot be without scale. On the contrary, the plane is not a point, so it allows matter to pass through, and it also allows people, as well as the matter used to build the valley's home, into the subspace.

In other words, before the Shadow Empire fell, it mastered more advanced space techniques.

If this is the case, Clara and Natasha should have expected that they would only be able to avoid the sudden attack of the intruders if they entered the subspace.

If they're still alive, they'll be in subspace, they'll be in the castle.

The internal structure of the castle was exactly the same as the one built by Chu Tianjiang himself, even the layout of the rooms, and the number of staircase steps.

It's just that Chu Tianjiang quickly discovered the problem.

This is the obvious trace of human life in the castle.

Before entering the castle, Chu Tianjiang noticed that the nearby farmland had been reclaimed, and even the irrigation channels had been maintained and repaired, but they had been abandoned for a long time. There are also waterwheels by the river, as well as the mills driven by waterwheels, which clearly show signs of use.

That is, someone has lived here and has lived for a long time.

It's just that Chu Tianjiang soon discovered that it was a long time ago, only a few hundred years, or even a thousand years ago.

Apparently, after coming to this subspace, Clara lived with Natasha for a long time.

Did they leave?

Chu Tianjiang couldn't help but be a little anxious.

According to the figures, avatars, and the ruins below the farm, Natasha's superpowers have been strengthened, and she has gained an infinite lifespan in the Age of Calamity. In other words, even if Clara doesn't have superpowers, Natasha is definitely alive. As long as she's here, she's alive. Chu Tianjiang prefers to believe that Clara will not give up easily, and Natasha will not let her go like this.

The question is, are they still here?

They built this subspace, and they must have left at will, so they didn't necessarily stay here, and they probably left a long time ago.

Also, the people of the Shadow Alliance used to take refuge here, perhaps for a long time.

Thinking of this, Chu Tianjiang couldn't help but sigh.

Obviously, Clara and Natasha are not here. If they were here, they would have been discovered by the Shadow Alliance a long time ago, and their existence would no longer be a mystery.

After taking a turn in the castle, Chu Tianjiang's guess was confirmed.

There really is no one, just an empty castle. In addition, outside the castle, leaning into the hill, there is also a cemetery built later, which contains hundreds of tombs, and the tombstones are engraved with some names that Chu Tianjiang did not recognize. It's just that there is no Clara and Natasha on it.

That is, there are many people who have died here and are buried here.

Perhaps, Clara and Natasha had never been here at all.

They built this subspace as a cover, or to provide a place of refuge for the orphans of the Shadow Empire, not here. They have lived on the ground for thousands of years, fought against the invaders for thousands of years, and there is no need to take refuge in subspace.

Besides, escaping is not Clara's and Natasha's way of doing things at all.

Chu Tianjiang was very disappointed, but he suddenly thought of a place, a place that he had neglected before and had not visited, a place where perhaps only Clara and Natasha knew the truth.
