Perhaps because of the passage of Wanshe, Xu Changqing, who returned on the original route, encountered no accidents again and soon reached the T-shaped intersection. He should have gone directly from the upward passage, but he stayed for a while and looked at the other end of the T-shaped passage with curiosity.

At this moment, Xu Changqing thought that the passage with the fire of life had benefited him a lot, and the other end of the corresponding passage might not be simple. After a little consideration, he decided to look at the passage on the other side to see if he could find new and useful clues and information, because he could not be sure whether the hexagram would have any adverse effects on the entire underground space after the damage. If he lost the opportunity to find new clues due to this negligence, he would probably not have time to regret it.

Xu Changqing, who made the decision, drilled out of the water from the passage that left the upwards, changed his breath, prepared for any concern, dived back underwater and swam into the passage on the other side.

This channel is completely different from the previous channel. The opening of this channel is very large, but it becomes narrower and narrower at the back. This narrowness is really narrow, the height remains unchanged, and the width is reduced. Xu Changqing needs to turn his body sideways to pass through at the back.

At first, Xu Changqing didn't know what the purpose of building this way was. It was not until he reached the end of the passage and entered another underground secret room that he understood what was going on, because at the exit was a corpse, a very strange corpse. The skeleton of this corpse was similar to human form, but the body was extremely thin, only half the width of the shoulders of different people, but it was very tall, and it felt like a crushed giant, looking extremely strange.

Only one skeleton was left in the corpse, and the flesh and blood had completely disappeared. Judging from the completeness of the bones, the other party died naturally, not due to external trauma. As for the cause of death, it may be poisoning or internal injuries. The lack of necessary clues, it is difficult for Xu Changqing to infer the truth.

In addition to its extremely strange appearance, the bones are also very interesting. The entire bones show the texture of mutton fat jade, which is very delicate. Xu Changqing picked up one of the finger bones and looked at it, and used the power of blood and energy to test it. He soon found that this jade bone can actually enhance the blood and energy power like a magic weapon to magic power, and the increase is very large. After estimating it slightly, it can reach at least five times the intensity.

Unfortunately, the bone has a fatal defect, that is, the blood and energy power injected into the bones is completely out of control like water splashed out. Even Xu Changqing could not predict what kind of reaction the blood and energy power would have after losing control. Just now, he just injected a blood and energy power into his finger bones. This blood and energy power was amplified by at least five times under the action of the finger bones, and then exploded instantly, making him feel like a bomb exploded in his hand. Even if he was on guard and responded in time, it still made his palms feel a little numb.

In Zhen Yuanzi's memory, there were many strange races in the ancient times, but these thin people were not among them. Judging from their bone structure, these thin people were more like secret people who settled in the Dayan Mountain area in the prehistoric world, because both hands and wrist bones had a very eye-catching prismatic bone, and the surface of this bone had some unique patterns since birth. This is a unique identity mark of the secret human race and the only feature that other prehistoric human races do not have.

Although the secret human race has its own clan, the root of the pursuit is the famous small human race from the Great Wilderness. It is only because of some reasons that the small human race undergoes some unpredictable transformation, and eventually forms the unique ethnic group of the Secret Human race. This ethnic group does not have extremely strong natural magical powers and blood power like other prehistoric tribes. They are very similar to the secular human races in the secular world today. They are all very weak in body, but have a very developed mind, and are good at creating some tools beyond imagination. For example, the earliest prototype of the floating boat in the three realms of Kunlun is the hand of the secret human race.

"Maybe I can do this!" The corpse in front of him aroused great interest from Xu Changqing. He did not rush to check other things, but instead talked to himself, using the knowledge of an anthropology expert in his mind and the incomplete memory of Zhen Yuanzi, he put together the scattered bones on the ground to form a complete human-shaped bone. Then he wrote down the positions and shapes of all the bones, shortened them in his mind, squeezed them about twice, and finally formed an image of a corpse with exactly the same bones but a huge difference in size.

After the image in my mind was formed, Xu Changqing had a definite answer to his previous guess. The corpse of this thin man was indeed a secret human race, but the body of this secret human race changed drastically due to unknown reasons, and the entire bone was more than doubled, becoming the current strange appearance.

Xu Changqing looked at the corpses on the ground, smiled on his face, and said, "It's true that it's a secret human race, so it's reasonable to have so many shocking buildings in this world."

The Secret Humans are one of the best skilled craftsmen in the prehistoric world. Many giants and powerful caves in the prehistoric era have Secret Humans involved in the construction. Even some god palaces in the other world also have the shadow of Secret Humans when they are built. At present, this magnificent building such as giant walls, towers, etc., is not so eye-catching among the various buildings built by the Secret Humans in the past.

After confirming that the corpse in front of me originated from the Secret Human race after the transformation of the physical body, Xu Changqing also affirmed one thing, that is, the Nuwa clan must be involved in the construction of the world, because the Secret Human race has been entrusted to the Nuwa Royal Palace since the ancient times, and any palace construction must be allowed by the Wa Royal Palace before people can be sent to participate.

After confirming the identity of the Secret Humans, Xu Changqing recalled all the information about the Secret Humans in Zhen Yuanzi's incomplete memory, especially some of the characteristics and techniques of the Secret Humans building palaces. If this is really built by the Secret Humans as he guessed, then he might be able to find more secrets hidden here through these related memories, and he doesn't even need to destroy the hexagrams according to the method he thought before.

In Zhen Yuanzi's incomplete memory, there are not many related contents of the Secret Human race, but these contents are very important. Almost all of them involve the mysteries and information of various crafts within the Secret Human race. After integrating these contents, Xu Changqing cannot be regarded as a Secret Human race's craftsman, but he is definitely an expert of the Secret Human race.

So, after quickly sorting out the information in his mind, Xu Changqing began to check the surrounding situation with the eyes of a secret human race. As a result, all the scenes he saw in front of him had a completely different feeling from before.

The underground space in front of me is almost exactly the same as the underground space at the other end of the passage. The only difference is that the hexagrams here are much smaller than that, and there is no small pool of fortune on the ground, and there is no fire of life in the sky. Instead, there is a cold spring in the middle of the underground space. The cold air of the cold spring spreads into the hexagrams on the entire space wall through the surrounding formations.

Xu Changqing's eyes swept around and finally fell on a floor under the corner of the wall not far from the right side of the entrance, and walked over.

This floor that Xu Changqing noticed was not conspicuous and was no different from other surrounding floors. Even the unique divine art formation talisman above was exactly the same. There was also a lot of cold air flowing under the floor under the formation of the entire underground space, injecting into the wall, and guiding it into the hexagrams.

Xu Changqing walked to the floor, looked down for a moment, and his eyes showed a little contemplative look. After about ten minutes, he saw him squatting down and his palms quickly slapped some divine talismans on the floor.

Just after Xu Changqing slapped the last divine text formation talisman and stood up, he saw that the divine text formation talismans he had slapped before suddenly became sunken a little bit, and then a gap was immediately opened on the wall in front of him that could only be allowed to Xu Changqing to go sideways.

"Sure enough, there is a secret room." Xu Changqing smiled on his face when he saw the changes in front of him.

The architectural skills of the Secret Humans are very extraordinary, but they also have a minor problem, that is, they like to leave some secret rooms in the palace they built that the palace owners do not know about, and put some interesting things in the secret room. When he checked this underground space just now, he brought his way of thinking into the Secret Humans' way of thinking, so that the entire underground space will appear completely differently in his eyes.

When Xu Changqing observed the structure of the underground space, there were many small questions that did not find answers, such as the pattern array connecting the small fortune pool, such as the patterns on the hexagrams, etc. Now, through the knowledge comparison of the secret human race, these questions have also been found one by one.

The patterns that he could not understand before were actually a variation of the secret human formation runes. Just like the body shape changes of the thin and secret human race, the unique secret human race of the secret human race had a very big change, so big that the writing method of the runes except the talisman part had completely changed, making the entire runes composed of the runes look like layers of patterns.

Guided by the secret human thinking mode, he quickly found the place where the most likely to add a secret room in the entire underground space. Then, by interpreting the variant rune arrays of the secret humans around him, he found the divine texts on the ground that could be replaced with other array symbols. He easily found a way to open the secret room.

Seeing that the secret room was opened successfully, Xu Changqing was also curious about the possible objects in the secret room. After carefully checking that there were no other dangerous traps in the passage, he turned his body sideways and moved towards the other end.
