Prince leikas did not continue to ask questions, nor did he reveal too much about the secrets of the endless abyss and his action.

It's not that they don't want to, but they have come to the portal not far from the underground base, which was tracked down by Chu Nan all the way before, but was destroyed in front of Chu Nan.

Prince leikas frowned slightly as he looked at the cliff that had been bombed into ruins.

"It seems that these guys have done a great job this time. They have cut off this road."

Then he asked Chu Nan, "what? Is it possible to restart the portal?"

"I'll try."

Chu Nan came forward and accurately found the original position of the portal from the ruins. Pressing the palm of his hand, internal breathing started, and the energy flow in the whole body space. He soon felt the space energy environment around the portal and the whole energy context in the portal.

After the portal burst open before, he had actually explored and studied the portal. Now he was familiar with the experience of restarting the portal leading to the 39th floor. In a short time, he mobilized sufficient space for energy injection, and soon a light rose in the ruins, showing the proper appearance of the portal.

"Did you succeed?" Asked Prince Lucas.

"No, it's not enough for people to pass." Chunan shook her head and waved to Angela Belle, Royal daughter Romanti and Carola.

The four people sat on the ground in a circle. Without Chu Nando saying, the other three people had stretched out their hands and held them together. Then the four people started their internal breathing at the same time, and soon gathered into a stream.

Prince leikas looked at the four people with great interest without disturbing them.

This should be the portal leading to the 41st floor, which is slightly different from the previous portal connecting the 39th floor and the 40th floor. Chu Nan readjusted the way of operating space energy, and it took a while to complete the debugging. The huge space energy gathered by the four people was injected into the portal as much as possible, and the light of the portal immediately became more intense and stable.

"Your Highness, now it should be the same as the previous portal. People can pass through. But..." Chu Nan hesitated. "For the sake of safety, should you go and try some people first?"

"I don't have so much time to find someone. Since you have succeeded before, I believe you can still do it this time." Prince leikas waved his hand and rejected Chu Nan's proposal.

Seeing Prince leikas walking towards the portal, the Royal daughter Romanti was eager to open her mouth to stop him. However, before he opened his mouth, Prince leikas had flashed and disappeared into the portal.

Romanti's daughter can only quickly recover her spirit and try her best to cooperate with the other three to maintain the portal.

Prince leikas didn't disappear for long, or he just disappeared at the portal, and he appeared again in the blink of an eye.

Facing the surprised eyes of the four people, Prince leikas smiled at them and said, "I just went to have a look. Those guys really didn't leave any ambush there. It seems that they think they have blown up all the portal leading to the 39th floor, and no one can come down. But they didn't expect that you can forcibly open the portal in this way."

Then Prince leikas waved to the four.

"All right, come with me. Let's go another way."

The four withdrew their breath in a fog and let the portal disappear again. Then they followed Prince leikas and flew in the opposite direction.

Prince leikas didn't fly fast at first. He seemed to be waiting for four people. Later, he saw that all four people could keep up and gradually accelerate. The speed of the five people became faster and faster. In about half an hour, he had flown out of a straight distance of more than 300 kilometers, and then fell in a valley.

Led by Prince leikas, the four people went into the valley to search for a moment, and finally found a cave at the foot of the mountain.

Drilling into the cave, I found that there was a long corridor leading to the depths of the surrounding mountains.

Continue to move towards the deep part of the corridor. After walking for more than 20 minutes, Chu Nan sensed that there was an energy fluctuation that was not obvious but clearly belonged to the portal in front of him.

Looking around the corner, I found a small portal with bright light standing in the huge space inside the cave in front.

"This is one of the hidden portals of the Imperial military. Don't say that ordinary adventurers don't know, even you royal children haven't revealed it." Prince leikas explained when he saw the surprised and suspicious face of the Royal daughter Romanti. "Those guys obviously didn't find it either. We can go directly to the 41st floor from here."

Seeing Prince leikas taking the lead to walk towards the portal, Chu Nan suddenly moved in his heart and asked, "Your Highness, since you have such a secret portal to the 41st floor, there should be the same secret portal to the 39th floor. Why do you want us to open the portal and let you take risks?"

"There used to be, but this time it was destroyed." Prince leikas had a gloomy expression on his face. "All the portals connecting the 39th floor and the 40th floor in the Empire were destroyed in the previous attack. We have no way to directly enter the endless abyss of the 40th floor. If the four of you didn't master the special method, we don't know what happened on the 40th floor."

"Really?" Chu Nan felt strange.

The portal they are now using is so secret, so it is reasonable to say that the portal connecting the 39th and 40th floors should be equally secret in the hands of the military of the dikland empire.

In this case, it is unreasonable that all these portals were destroyed and none remained.

Those guys on the other side are unlikely to have the same position of so many portals, and the only way they can do this is for the intelligence to leak out from the inside.

In other words, the military of the dikland empire... May have spies.

Thinking of this, Chu Nan couldn't continue to ask, so he could only follow Prince leikas into the portal silently.

The energy environment of the whole body space changes as usual, which is no different from that when passing through any portal before.

The scenery in front of us also changes. With the stability of the energy environment, it gradually stabilizes and finally becomes clear.

Surprisingly, it was full of green and the air with obviously high oxygen content was also filled with the fresh aroma of grass and soil, which made people feel refreshed immediately after taking a breath.

Chu Nan's four people couldn't help but show joy at the same time.

Since entering the twenty floors of the endless abyss, the environment in each floor, if not particularly bad, is definitely not much better. Now, suddenly seeing such a vibrant and green place, I am naturally happy, and even a smile appears on Carola's face.

Only prince leikas, with no change in his expression, waved to the four to follow, then flashed and left the portal first.

Under his leadership, the four continued to fly rapidly in the 41st floor, found another portal, and went to the 42nd and 43rd floors again

The surrounding scenery changed rapidly, and the five people continued to move deeper into the endless abyss.

In this process, Chu Nan clearly sensed that the energy environment of the whole body space began to change with the deepening of each layer.

This change is not strong, but it is very obvious in Chu Nan's induction. He can feel that the spatial energy in the surrounding environment is becoming more viscous, and he is no longer able to control at will.

If he didn't understand what was going on before, he probably understood what was going on after hearing Prince leikas's explanation just now.

If the endless abyss is a large area in the center of the whole galaxy, the deeper the endless abyss, the closer it should be to the real silver center.

Obviously, the closer to the silver core, the greater the change of space energy environment and become more and more viscous.

In fact, this phenomenon was observed by human beings a long time ago, and there is a set of relevant theories.

Chu Nan has not studied this theory, but generally speaking, it is because the closer he is to the silver center, with the significant increase of the planet density, the gravitational environment in the surrounding space becomes more and more complex, and the space energy environment under the action of strong gravity is also affected, with slow and stagnant flow and so on

Chu Nan didn't care about this theory before, because he never thought he would really come to the universe so close to the silver heart one day.

Now it's really coming. Thinking of this theory, Chu Nan can't help but have reverie in his heart.

After many martial arts practitioners have achieved success in cultivating martial arts skills, they will show a certain contempt for science because of their own strength. It is really strong to generate personal strength. Science is just an idea with the help of external forces.

For example, the practitioners of the universe can't explain this phenomenon more clearly by using the space alone, but they can't use it perfectly by themselves.

Because of this, many martial artists feel that they even know more about the human body than those top scientists, so they are elated.

Of course, Chu Nan doesn't have this idea. The reason why he thinks of this now is because the theory about the energy environment of the silver heart thinks of his current situation.

If this special environment becomes special due to the influence of gravity, can the surrounding space energy environment become stable if the influence of gravity in the surrounding environment is shielded?

However, if you want to obtain such a space that is shielded from gravity, you can't do it casually.

Chu Nansi thought about it and found that only one space that can be created by a martial artist can meet this condition, that is, the field.
