The next day, after cultivating overnight, Han Feng's fighting spirit had also improved greatly, and vaguely, he already felt that he was about to advance again.

Just when Han Feng was happy about this, Xiao Yu came to the door.

"Your Highness, what is the matter with you coming to me?" Han Feng looked at Xiao Yu and couldn't help asking.

When Xiao Yu heard this, he couldn't help but smile bitterly and said: "Have you forgotten that yesterday my father promised to let you go to the royal treasury to choose a few things as a reward for you to be crowned a prince, and I came to you and took you to the treasury." ”

"I see, yesterday because I talked to His Majesty about the alchemy conference, I forgot about it. Han Feng said with a little embarrassment.

Xiao Yu shook his head with a wry smile again, and then led Han Feng to the royal treasury together.

Along the way, Han Feng was not so surprised by the location of this treasure house. Because Han Feng had also entered the royal treasury once when he was in the Tianyue Empire before, and although the Tianxing Empire was different from the Tianyue Empire, in the final analysis, they were all inherited from the same bloodline, and in some aspects, they were very close, and there were no exceptions to this royal treasury.

After walking for a while, Xiao Yu finally took Han Feng to a very ordinary building, and then said: "This is the location of the treasure house, someone will open the door for you in a while, you can rest assured that you can choose what you like inside." It's the first time I've seen my father be so generous to people, Han Feng, you should cherish such an opportunity. ”

"Thank you, Your Highness. Han Feng replied with a faint smile.

Xiao Yu nodded, and then said: "Okay, I don't have anything to do next, I still have some things to deal with outside, so I won't wait for you." ”

After speaking, Xiao Yu said a few words to the person in charge of the treasure house, and then left in a hurry.

Seeing Xiao Yu leave in a hurry, Han Feng also shook his head slightly, and then walked into the huge treasure house under the leadership of a guard.

Entering the treasure house, Han Feng found that the building structure in this treasure house was no different from that of the Tianyue Empire.

If it weren't for Han Feng's determination that he wasn't dreaming, I'm afraid he would have regarded this place as the treasure house of the Tianyue Empire.

I drove all the way to the deepest part of the treasure trove and looked around a little.

Sure enough, it is worthy of being the royal family that rules an empire, and the things collected here are not much better than those of the Tianyue Empire, and even Han Feng feels that the treasures here are much better than the treasure house of the Tianyue Empire.

In addition to some precious materials, there are also a large number of antiques, calligraphy and paintings, and some very rare collectibles.

Of course, for these things that were priceless but meaningless, Han Feng just glanced at them in a hurry, and directly ignored the past.

In the treasure house, walking back and forth several times, Han Feng was really dazzled by the various treasures on display in front of him.

Although Xiao Jin did not limit how many treasures he could take, Han Feng was self-aware and did not dare to take more. Otherwise, Xiao Jin knew about it and wouldn't pick his skin.

Therefore, after Han Feng turned around a few more times, he chose a relatively rare eight-grade material, Blood Spirit Jade.

Although this blood spirit jade only has eight grades, it can be used to refine the elixir, and it is a little buffer for other mutually exclusive materials, which is more conducive to the success rate of the elixir refining.

Therefore, this blood spirit jade itself does not have much function, but it is still the reason why it is rated as an eighth-grade material.

After selecting this blood spirit jade, Han Feng turned around a few more times, and then his eyes immediately focused on the pile of books placed on the corner.

Han Feng took a casual look and found that most of these books contained some very ancient and rarely heard of secret books.

Perhaps because these cheats had been stored in the royal treasury of the Celestial Star Empire, Han Feng didn't know anything about them in his previous life.

After flipping through a few books at random, Han Feng found that the mental techniques and martial arts recorded in these secret books were also very high-level. However, it aroused Han Feng's interest too much.

As the saying goes, people's hearts are not enough to swallow elephants, in Han Feng's memories of his previous life, as well as in Ye Zhenfei's cave mansion before, all the mental martial arts that he knew were far beyond the scope of Han Feng's use, so even if these mental martial arts in front of him were also very high-level, for Han Feng, they didn't have much effect.

After looking at them for a while, Han Feng lost interest in these cheats, and just as he was about to leave, his eyes did inadvertently aim at the corner of the lowest level of the bookshelf, where a very meager book lay quietly.

The reason why he was able to attract Han Feng's attention was not because of anything special about the appearance of this book, but because Han Feng found that there were a few big characters written on it.

These big characters do not belong to the script of the Celestial Star Empire, or to the script of any country on this continent.

Because, Han Feng recognized these words. These words are exactly the same as the words recorded on them when Han Feng got the Proud Heaven and Earth Secret back then.

With such curiosity, Han Feng immediately took out the book that was covered with a thick layer of dust.

Stretching out his hand and patting it slightly, the dust on the surface was completely scattered, and suddenly several conspicuous big characters appeared in Han Feng's sight.

"Breeze Trick!"

Thanks to Han Feng's previous research, he had spent a lot of time deciphering these strange words, so he could easily recognize the words recorded on them at this moment.

With strong curiosity, Han Feng turned it page by page.

With the continuous in-depth understanding, Han Feng was gradually attracted by the content in this Qingfeng recipe.

According to the description in the book, this Qingfeng Technique is not a high-level mental technique, nor is it a certain martial art, according to Han Feng's understanding, this Qingfeng Technique should be a special technique between the mental method and the martial arts.

In other words, this Qingfeng technique should be regarded as an auxiliary exercise. That is, when you are cultivating a mental method, you can still cultivate this Qingfeng Technique.

And the effect of this Qingfeng Technique is to improve the cultivation ability to control the fighting spirit.

As we all know, a person's cultivation of Dou Qi is to increase the energy in the body, and martial arts are used to bring these energies out of the body and produce extremely strong destructive power.

The more advanced the martial arts, the one is to use the least amount of fighting energy and exert the strongest power. Therefore, this is a very high requirement for the ability to control the fighting spirit.

According to the above mentioned in this Qingfeng Technique, as long as the martial artists practice their own mental methods at the same time, they can also practice together with this Qingfeng Technique, they can relatively improve the martial artist's ability to control martial arts.

So as to improve the strength of the warrior in disguise.

Seeing this, Han Feng was also very happy in his heart, if he followed what was said above, then this Qingfeng Jue was indeed a good thing.

Moreover, this Qingfeng Technique was not the only one he could use, he had already thought of teaching this Qingfeng Technique to the various disciples of Xuantian Sect, so that in the process of cultivating Dou Qi, even this Qingfeng Technique would be cultivated together, so as to improve their overall strength.

In this way, the overall strength of Xuantian Sect will definitely be able to be greatly improved.

Thinking of this, Han Feng had already decided to take this Qingfeng recipe with him.

In fact, the more important point is that Han Feng paid great attention to the words recorded on this Qingfeng Recipe, he had already had a Proud Heaven and Earth Recipe before, and now there was a Qingfeng Recipe.

Is there any connection between these two exercises written in the same script?

Could it be that the two were created by the same person, that is, the Wuji real person mentioned above the Proud Heaven and Earth Formula.

If so, then what is this Wuji real person who is sacred, and why has no one ever heard of it for thousands of years.

In addition, these words that are far from belonging to this continent, what are they, is it that Han Feng is too lonely and unheard of, and has never seen such rare words, or these words are created by the Wuji real person.

All this is a mystery to Han Feng.

As for the exercises he cultivated, Han Feng naturally wanted to figure out this matter very much.

Therefore, his interest in this Qingfeng Jue is not in the exercises recorded above, but more in the hope of finding a clue about the real person of Wuji from it.

And just as Han Feng put away the Qingfeng Jue, unexpectedly, a thin piece of paper fell out of the crack of the Qingfeng Jue.

Han Feng picked it up suspiciously, opened it and found that it seemed to be a map drawn on the paper.

It's just some strange marks on it, and Han Feng doesn't recognize it.

In particular, in the upper left corner, there is a mark with a thick middle and two pointed ends, and at each end of this mark, two strange characters are drawn.

The shape on it resembles a stick that has been folded into three sections, but it bears some resemblance to an irregular thunderbolt. And the one below is like a curved snake-like demonic beast, a thin one.

Then the entire map was surrounded by dense forests, Han Feng carefully distinguished, and found that the shape of this map seemed to be very familiar, but he couldn't remember it for a while.

Moreover, the words marked on this map are the same as those recorded on the Qingfeng Jue, which are different from those on this continent.

Could it be that this is the hiding place that the Wuji real person left for future generations?

Han Feng guessed, but then shook his head and pushed this thought out of his mind.

Han Feng put the map away and took it out along with the Blood Spirit Jade and Qingfeng Jue that he had selected earlier.

As for other things, it's not that Han Feng doesn't need them, or they don't have any value.

It's just that Han Feng knew that this was Xiao Jin's blood capital in order to win him over, but he naturally knew that there was no lunch in the world for nothing.

Therefore, in order to avoid owing too much favor to the royal family, Han Feng originally just took one or two random pieces as a symbol of his surname, but he happened to meet the blood spirit jade, as well as this Qingfeng Recipe that outsiders couldn't understand at all.
