When they passed through the corridor again, what appeared in front of them was a towering giant tower, the top of the tower was very high, and they couldn't see how many floors there were, there was a large door on the first floor of the giant tower, and the plaque of the door had three big characters written on it, "Xinghe Tower".

When Xiao Yu and the others came to the gate of the tower, the door creaked and opened automatically, obviously someone invited them to enter the tower, since they had come here, there was no point in scrupling too much, so a few people entered the tower.

At the moment of stepping through the door, Xiao Yu felt like he had entered another shijie, everything outside seemed to have lost contact with him, and then looked at the three girls around him, there were still their shadows, he hurriedly shouted at Xiao Jiumei, but he could only hear a faint echo, but he didn't even respond at all.

There are strange things everywhere in the Cangling Secret Realm, and now he is no longer surprised, after all, he has not sensed any crisis in the little ninth sister, he temporarily put his mind at ease and began to familiarize himself with the environment in front of him, he thought that this was also a test.

However, when he raised his head to observe the surrounding environment, what caught his eye was a brilliant galaxy, when Xiao Yu was young, he often watched the stars with his younger brother and mother, but at that time, the starry sky was far away from him, and the starlight was not so dazzling.

But now, he felt as if he was in the middle of a galaxy, and even he had become a bright star, and the other stars surrounded him, building a gorgeous starry sky with him, and he couldn't believe that those stars were so close to him that he could almost touch them with his hand, but when he really wanted to touch them, he found them so far away from him.

At the moment when Xiao Yu raised his hand, something incredible happened, those stars formed a beautiful star map according to the trajectory of his arm, and when his arm waved again, the star map would also change, Xiao Yu felt like the master of this starry sky.

When he looked at those star maps, there was always a sense of déjà vu, but when he looked closely, it seemed to be covered with a thin veil, and there was no way to see clearly, so he had to gather all the power of the primordial gods and observe with his divine thoughts, but he still found nothing.

Zuihou closed his eyes, felt with his heart, touched with his thoughts, and finally he sensed an extremely fine silk thread on the surface of each star, which pulled each star and moved according to its unique rhythm.

Xiao Yu didn't use a little of the power of the Yuan Shen now, but the patterns on the star map became clear, although he didn't know what these patterns represented, but he could always get a trace of understanding in the star map.

Xiao Yu knew that this was a rare opportunity, but he was not greedy, but condensed all his thoughts on a map, peeling off the cocoon little by little, following the silk thread implicating the stars, peeking at the whole picture of the star map, zuihou finally presented a complete star map in Xiao Yu's mind.

No wonder Xiao Yu felt a little familiar, the scenery depicted in this star map was very similar to the scene he had comprehended in the ancient song, but the scene in the star map was more real, more specific, and the content was richer than the scene he depicted.

Then he clearly presented the scenes of several other star maps in his mind one by one, and he was pleasantly surprised to find that the scenes depicted in the star maps were strikingly similar to the scenes described in the qin music, and that similarity was a feeling, an artistic conception that was difficult to describe in words.

At this moment, he found that his comprehension of the ancient song was more profound, although he had not fully comprehended the true meaning contained in the ancient song, but it had gradually become clear, at this time he had clearly seen ten star maps, and he was looking at other star maps, but he couldn't see it clearly.

He couldn't help but feel a little pity in his heart, and a long sigh unconsciously rushed out of his mouth, this was a voice that sounded in Xiao Yu's ears: "Xiaoyou, you have such a harvest the first time you entered the Star River Tower, aren't you satisfied?"

The voice was still so ethereal, there was no way to know the location of the person who spoke, but Xiao Yu had already heard it, this person was the one who asked himself three questions in the labyrinth, and then planted a seed in his own primordial spirit, and he didn't expect to be here.

Xiao Yu hurriedly bowed deeply into the air and said, "The seniors are here, but they still have to guide the juniors, so I ask the seniors to give the juniors a chance!"

"Little friend, you don't have to be polite! Little friend knows what the Tao is?" the man asked leisurely.

"The Tao is the principle of heaven and earth, and all things return!" Xiao Yu replied.

"Then what is the reason of heaven and earth?"

"The supreme principle of heaven and earth is the law of the operation of all things!"

"Where does the law of the operation of all things come from?"

This sentence stumped Xiao Yu, his cultivation time is still short, it is already rare to have such a feeling, such a profound truth, he can understand it, so he said respectfully: "The younger generation is dull, please also ask the seniors to teach!"

The man said three times, and then said: "Xiaoyou can know, 'Man is the law of the earth, the earth is the law of the sky, the heaven is the law of the Tao, and the Tao is the law of nature!' Where does the Tao come from, where the Tao comes from nature, where is nature, and nature is in the hearts of people!"

Hearing these words, Xiao Yu still didn't understand the true meaning, and his mind was still chaotic, but he vaguely understood something, but when he wanted to ask a little more clearly, he found that the old man had long since disappeared, no matter how he called, there was no response.

Xiao Yu knew that if he wanted to understand the meaning of these words, he was afraid that he would only spend more time and experience to comprehend them, but fortunately, he was not in vain in this Star River Tower, at least his cultivation on the piano path had improved a lot, and now that he was performing the ancient song again, his attack power would definitely be extraordinary.

Now in this Star River Tower, Xiao Yu has no way to get more things, so he wants to exit the Star River Tower to find Xiao Jiu Mei and them, but he has no way to find the door when he enters.

At this time, Xiao Yu felt a liliang wrapping around him, he was just about to resist, the scene in front of him instantly became blurred, he unconsciously closed his eyes, and the restrained liliang on his body suddenly disappeared, he opened his eyes and found that he was already outside the Star River Tower.

Xiao Jiu Mei and a few people were not far away, looking very anxious, seeing Xiao Yu finally appear, they all ran to his side happily, Xiao Jiu Mei and Ling Caiyan didn't know what was going on, as if there were tears in their eyes, even Su Yu was sullen.

At this time, Xiao Yu was looking at the Galaxy Tower, and found that his own image was hanging on the tenth floor of the tower, and the images of Xiao Jiumei and Su Yu were also hanging on different levels, Xiao Yu probably guessed that he might have realized ten star maps, and maybe a star map corresponded to one floor!

Everyone had already come out of the Xinghe Tower, but Xiao Yu found that he didn't know when there was an extra jade plaque in his hand, and there were four small characters engraved on the jade plaque, which were all written with ancient runes.
