The villains are redeemed, and the heroines cry and beg for forgiveness.

The older sister sacrificed so much for her younger sister and for the Niyuan Martial Arts Academy.

If only she hadn't broken through to the Golden Core realm of martial arts at that time.

Perhaps she could help her sister, or at least see her sister one last time.

Instead of finding only her sister's grave when she excitedly returned to the Reverse Yuan Martial Arts Path.

......

In the light screen.

Gu Ran was indeed very interested in what Cheng Caimeng had said.

If he had a suitable weapon, his combat power might increase even further.

At that time, he will be able to kill these extraterrestrial aliens more easily.

Perhaps we could even develop a group attack using "insectoids" capable of annihilating the combat power of these martial arts masters, which would be more labor-saving and time-efficient.

Although his current combat power can be said to be completely dominant in the Human Alliance, because so far he has not encountered an opponent who can fight against him.

But he is also human, and he would also be exhausted if faced with an endless stream of alien species.

Cheng Caimeng led Gu Ran and Xue Xiling through a room and two corridors before stopping and pointing to a large open space in front of them, saying, "This is it."

"What weapon? Where is it?" Gu Ran didn't mince words. After scanning the area, he got straight to the point, "I'll give it a try."

Cheng Caimeng led Gu Ran to a place that wasn't far away; it was the training ground of the Niyuan Martial Arts Hall.

It's the place where Gu Ran first saw Cheng Caimeng practicing sword dance, fluttering like a colorful butterfly.

"Don't worry, you'll see it soon."

Cheng Caimeng bit her finger and smeared the blood on a pillar beside her. Then she began to circulate her cultivation technique, continuously pouring spiritual energy into it.

Gu Ran watched with some surprise as the floor of the training ground slowly opened, revealing an underground space.

This place is really well hidden; he didn't even notice it when he came last time.

However, he didn't actually intend to explore the underground of the martial arts hall when he came last time; he just roughly scanned the area of ​​the martial arts hall with his telekinesis.

As Gu Ran watched the ancient staircase extend into the deep, bottomless darkness, a sense of curiosity arose within him, and he tried to use his mental power to explore it.

However, to Gu Ran's surprise, this martial arts arena seemed to be built with special materials. When he used his mental power to investigate, he found that the ground beneath the arena felt like just a layer of ordinary soil.

But what appeared before Gu Ran was a mysterious underground space.

A disguise that can fool my telekinesis?

When Gu Ran used his mental power to explore the entrance in front of him, he found that he quickly reached the end, as if it were just an ordinary basement.

Gu Ran looked at Cheng Caimeng with some confusion.

"This is a relic passed down through generations of our Ni Yuan Martial Arts Hall. If we're talking about its origins, it can even be traced back to the sect era. However, I don't know exactly which period of the sect era it can be traced back to."

Xue Xiling, who was standing to the side, widened her eyes in surprise.

This is an ancient relic of the Niyuan Martial Arts Hall, passed down for who knows how many years.

She finally understood why Cheng Caimeng had said it concerned the secrets of the Ni Yuan Martial Arts Academy and asked her to temporarily leave.

However, Xue Xiling was a little confused about the idea of ​​avoiding it. Hadn't such a confidential matter already been told to her?

Seemingly guessing what Xue Xiling was thinking, Cheng Caimeng glanced at her and said, "I trust Researcher Xue's character. She will keep quiet about everything she sees and hears. However, the real secret is how to enter the ruins to challenge the trial. This is something Researcher Xue needs to avoid."

Xue Xiling knew that Cheng Caimeng didn't call her "Miss Xue" but addressed her as a researcher, which was a way of reminding her to keep this matter a secret.

Researchers place great importance on character; academic misconduct can ruin one's entire future.

Xue Xiling understood what Cheng Caimeng meant. She smiled and said, "That's only right. Don't worry, I won't tell anyone about the secret of the Ni Yuan Martial Arts Academy, not even my father."

Cheng Caimeng nodded to her: "Then thank you very much, Researcher Xue. Okay, I will lead the way now. Remember to stay close behind me and don't be surprised no matter what you see."

Then Cheng Caimeng took the lead and entered the dark space below.

Gu Ran didn't sense any danger and followed Cheng Caimeng inside without hesitation.

Xue Xiling then pulled on Gu Ran's sleeve and walked behind him.

She was still a little scared of such a dark environment, and subconsciously moved closer to the place she felt safest.

......

Outside the light screen.

Everyone was also very curious about the ruins of the Ni Yuan Martial Arts Hall.

They had already seen the ruins of the merfolk.

If it weren't for that ruin, the merfolk wouldn't have been able to produce so many powerful empresses throughout history.

So what about the ruins of the Reverse Yuan Martial Arts Hall? What's inside?

"Could it be that the cultivation technique hidden inside is one that allows one to reach a level beyond the Golden Core stage of martial arts?"

Suddenly, a powerful figure guessed.

"Could the rumors be true?"

The powerful figures all recalled the rumor that the Reverse Origin Martial Arts Hall possessed a technique that surpassed the Golden Core realm of martial arts, and then looked at Cheng Youmeng with burning eyes.

Cheng Youmeng had previously denied the rumors, but at this moment they were more inclined to believe that Cheng Youmeng was lying, in order to prevent them from coveting that cultivation technique.

Cheng Youmeng frowned; how could she not know what those people were up to?

"I'm not lying to you. At least I had no idea that our Reverse Origin Martial Arts Academy possessed such a technique. Otherwise, why wouldn't my sister and I have practiced it?"

Upon reflection, everyone agreed that this made sense.

However, Cheng Youmeng's statement could not completely extinguish the burning passion of all the martial arts experts present.

Not cultivating doesn't mean you don't have it. Perhaps the conditions for cultivation are too strict and you two sisters don't meet them. Or perhaps you are actually cultivating this kind of technique, but you haven't reached the highest level of the technique, and you are deliberately pretending that you are not cultivating this technique.

In short, there are many possibilities.

They were convinced by Cheng Youmeng's statement before because they weren't really sure themselves; there was no evidence to prove the rumor before. But now, they have seen "evidence."

Although the occasion may seem somewhat inappropriate, the allure of techniques that surpass the Golden Core stage of martial arts is too great for martial arts experts.

Even if they cannot switch to other cultivation methods (a martial artist can only cultivate one type of martial arts golden core, and once they reach the martial arts golden core realm, they cannot switch to other cultivation methods. However, under normal circumstances, even a martial artist who has reached the martial arts condensation stage will not give up the cultivation method they have cultivated for many years to switch to other cultivation methods), they can still learn from it. Perhaps they can improve the cultivation method they are currently cultivating and then break through to the martial arts golden core realm.

Since humans began cultivating martial arts, there has been no record of any martial artist who has surpassed the Golden Core realm.

The Golden Core of Martial Arts is the highest realm of martial arts known to humankind.

Even the ancestor of martial arts only speculated, based on various legends passed down, that he possessed power beyond the Golden Core realm of martial arts.

However, the legend has been passed down for nearly two thousand years, and the process of transmission inevitably led to distortions, such as embellishment and fabrication by later generations. Therefore, many people do not regard the ancestor of martial arts as an existence that transcends the Golden Elixir of Martial Arts.

Cheng Youmeng felt somewhat helpless. As a martial artist, she naturally knew how coveted a technique that surpassed the Golden Core stage of martial arts would be if it truly existed.

But she really didn't know; she had never heard her sister mention it.

However, looking at the ruins that appeared on the screen...

"Perhaps it was because Master Cheng's older sister kept it from her. Master Cheng and her sister had a very good relationship. Logically, she should have told her younger sister, but such a secret could easily lead to trouble. So Master Cheng's older sister kept this secret in her heart and never told her younger sister."

Some people realized that Cheng Youmeng wasn't lying and offered a different interpretation.

"There is such a ruin inside the Ni Yuan Martial Arts Hall. Actually, I didn't know that. Perhaps there is a technique that surpasses the Golden Core stage of martial arts, as you mentioned. Perhaps not. I... can't be completely sure right now. But didn't you hear? My sister is going to give Gu Ran a weapon, which means that this should be a place where peerless divine weapons are hidden, rather than some technique that surpasses the Golden Core stage of martial arts."

In fact, after listening to what others were saying, even Cheng Youmeng herself became a little suspicious. Did the Niyuan Martial Arts Academy really have a technique that surpassed the Golden Core stage of martial arts?

However, she still did not completely change her tune.

"Alright, we'll find out soon enough whether it's true or not." Cheng Youmeng looked at the screen and ignored them.

If some ignorant people want to "borrow" this fictitious martial arts manual to harass her, she wouldn't mind showing them her years of hard work.

Cheng Youmeng is very powerful. If she hadn't betrayed us, the allied forces would have had to spend a lot of effort and sacrifice a considerable number of people to attack Meteor City and Meteor Building.

They didn't want to fall out with Cheng Caimeng, and they also felt it would be safer to check the contents of the screen again to confirm.

......

In the light screen.

Gu Ran only realized why his mental powers couldn't detect the true nature of the mysterious underground space when he stepped into it.

Because this was actually a "corridor passage" composed of individual small spaces, his mental power could not penetrate through the layers of space, so he could only explore within one layer of space.

The result was that the investigation was easily completed.

As for the material used to cover the entrance to the relic passage in the foundation of the training ground, Gu Ran knew that it should also be some kind of material that could resist telekinetic detection. After all, he had encountered buildings and materials that could block telekinetic detection before.

Gu Ran didn't know how long they had been walking. During that time, Gu Ran knew that they had passed through many repeated small, independent spaces, thanks to his keen sense of space.

It's as if these individual small spaces can be randomly shuffled like a deck of cards.

"Spatial ability? This application method is quite interesting," Gu Ran thought to himself, while wondering who helped the Ni Yuan Martial Arts Hall build such an underground space.

"Here we are."

Suddenly, Cheng Caimeng, who had been walking silently ahead, stopped.

Before them lay a seemingly endless, isolated space.

In this infinitely extending independent space, something that looked very familiar to Gu Ran floated not far in front of him.
