Knowing the way to enter the underground imperial city, of course Qin Wu had to go again immediately, the first time he went in and found nothing, it didn't mean anything, after all, at that time, he didn't know that this might be the underground imperial city, and there was a high probability that he would not succeed in finding the entrance.

Qin Wu got a cat according to Zhao Li's words, which was completely different from the one he saw yesterday, which he had caught from Senior Sister. In fact, Qin Wu didn't want to catch Senior Sister's beloved cat, and it seemed that Senior Sister had a cat because of the huge Yanyue Sword Sect when he slept.

Qin Wu caught the cat and came to the place where he entered the underground imperial city yesterday, and strange things soon appeared, the cat that was originally very quiet in his arms suddenly exploded and broke free directly from his arms, but the courtyard that he couldn't find yesterday appeared, and such a thing made him stunned.

How does this work?

Qin Wu didn't know anything about the way of the formation, so he naturally didn't understand the principle of this special formation opening method, and there was also the fact that everyone else seemed to be dead when they entered here, and why he was able to come out unharmed. There were too many questions, and it was impossible for Qin Wu to get answers for the time being, so he climbed over the wall and entered the courtyard. It didn't look any different from the outside, it was still daytime, if it weren't for yesterday's experience, Qin Wu would have really been deceived by this scene.

Of course, Qin Wu still couldn't see anything, the sky seemed to be no different from the outside, and he found that he couldn't figure it out at all, so he quickly gave up this question.

Qin Wu reappeared in the main hall, his eyes swept over the scroll of the hidden sword technique, and he began to search in the main hall. The main hall is very large, but there is nothing Qin Wu needs here, what he needs to find this time is a drawing that records the situation of the underground imperial city.

Qin Wu's search was still very careful, but what made him depressed was that he didn't find any drawings about the underground imperial city at all, which had to make him very frustrated.

Of course, Qin Wu was not one to give up so easily, he quickly came to the study, and his eyes were quickly attracted by a book that looked like it had been a long time on the outside.

This must belong to a certain prince's study, and the things that can be put in the study are definitely high-quality, even if they are not martial arts cheats, they are also a lot of precious books. The cheats in the entire study are basically very new, and at this glance, you know that they are rarely read, but in Qin Wu's eyes, this book is different, it is often read at a glance, so the appearance is obviously seriously worn.

What can make a prince not play with it?

Of course, Qin Wu was curious, so he took the notebook in his hand.

It turned out to be a cultivation note!

Qin Wu showed a look of surprise on his face after opening the book, he originally thought it was something amazing, but he didn't expect that it was just about how to cultivate the True Dragon Sword Technique. Qin Wu simply glanced at it, and then lost interest, what was said above was undoubtedly that the "True Dragon Sword Technique" had lost the foundation building part, and this prince had spent a long time without successfully cultivating the first three layers. The entire book is recorded in this prince's cultivation, and many contents can be seen at a glance in Qin Wu's opinion, which is naturally of little use to him.

However, Qin Wuzhi did not despise this prince, after all, without the foundation building sword technique, it was still very difficult to cultivate the "True Dragon Sword Technique", if he hadn't accidentally obtained the "True Dragon Desire Immortal Technique", I am afraid that he would be at a loss against the "True Dragon Sword Technique".

Since the cultivation experience was of no use to Qin Wu, he naturally had no interest in reading it, but just when he wanted to put down the cheats, he accidentally saw a sentence, which made him stunned.

"Refining the first three layers can activate the True Dragon Town Immortal Diagram and open the biggest treasure hidden by the Qin clan, what is this?"

Qin Wu saw the words left by this prince in his notebook, he could see the other party's deep regret and depression, obviously this guy had exhausted his life and failed to realize the third layer. But that's not the point, what Qin Wu cares about is the True Dragon Town Immortal Diagram mentioned by this prince.

What is this?

Qin Wu hurriedly flipped through the book, but unfortunately the content in it was all cultivation notes, and there was no further mention of this True Dragon Town Immortal Map. Of course, Qin Wu would not be so simple, he began to open all the books in the study, and it turned out that his luck was not bad, and he quickly found a depiction of the True Dragon Town Immortal Map.

Underground Imperial City - True Dragon Town Immortal Map?

Qin Wu was stunned when he saw this information, according to the information he found, the underground imperial city is not a building, but a special immortal weapon, and the key to open this thing is the "True Dragon Sword Technique", if you want to enter the True Dragon Town Immortal Map, that is to say, the underground imperial city, you can only practice the "True Dragon Sword Technique" to the third level of perfection.

What are the characteristics of this True Dragon Town Immortal Diagram?

Qin Wu was very surprised, if the underground imperial city was transformed by an immortal weapon, then what would happen if he collected this immortal weapon?

Legend has it that there is a way to leave the Imperial City when you enter the underground imperial city, and it seems that this legend should be wrong, but Qin Wu feels that things are not so simple, because according to the information he left from the Qin Palace, the underground imperial city does have a passage to the outside of the city.

According to the information here, this underground imperial city is the transformation of the True Dragon Town Immortal Map, so all the external passages must be the same as the entrance to the Yanyue Sword Sect, which is closed under normal circumstances, and if you want to enter it, you can only do it under special circumstances. Therefore, if Qin Wu can enter the True Dragon Town Immortal Diagram, he doesn't have to worry about someone coming in to find trouble for him, after all, the key to be opened is the third-layer True Dragon Sword Technique, and others have not practiced this set of exercises, so they don't have the possibility of opening it at all.

Qin Wu's face was a little solemn, he knew that things were a little different from what he imagined, so whether he could use the information he saw from the information to run away depended on what this True Dragon Town Immortal Diagram was.

Is the key to unlocking the three-layer "True Dragon Sword Technique"?

Qin Wu's brows furrowed, this difficulty was still very great, he had indeed cultivated the True Dragon Sword Technique, but it was only the first layer. Cultivating the sword technique is not only about cultivating the sword moves inside, but also about the internal strength of the heart method, obviously if you want to practice to the third level of the "True Dragon Sword Technique".

The sword move was comprehended on the first day, but Qin Wu was not sure that he could quickly practice to the third layer, this thing not only needed comprehension, but also time, at least it would take a few days for the first layer to be consummated.

It seems that after entering the world of swords, I will also speed up my cultivation, which can shorten the time by half.

Since he knew the real way to enter the underground imperial city, of course Qin Wu had to start cultivating the True Dragon Sword Technique immediately, there was no problem with the sword moves, he had done it yesterday, what he had to do now was the internal strength of the heart method, this thing needs to be practiced constantly, there is no shortcut at all.

The cultivation of the inner strength and mental method is generally meditation, of course, the practice of the sword can also be cultivated, and the effect is also very good. If Qin Wu wanted to speed up his cultivation, there was no doubt that the combination of the two was the most perfect choice.

Cultivating here?

Qin Wu didn't do this, this place was completely isolated from the outside world, and it was indeed a good place to cultivate, but it was still very troublesome for him to disappear for a whole day, so it was most appropriate to return to the Yanyue Sword Sect to cultivate.
