The mountains are still the same, and the sun is rising.

The courtyard where Su Yu was at this time was halfway up this mountain.

Although the courtyard given to him by the elder of the Xuanwu Hall was the closest place to the residence of Nalan Yanran at the top of the mountain, it was only relatively close.

Nalan Yanran went up the mountain at the age of ten, and then because of her extraordinary talent, she was accepted as a disciple by Yun Yun, the sect leader of the Yunlan Sect, and five or six years have passed now.

Such time is enough for those later admirers to think carefully.

So it's no surprise that his current residence is halfway up the mountain.

After cleaning up the yard that had just been disturbed by the whip of the Mo family's young lady, Su Yu walked out.

The target was directly aimed at the library hall of the Yunlan Sect.

Because his strength was improved because of the upgrade card, and whether he had drawn secrets or not, Su Yu didn't have time to learn exercises and fighting skills.

From the short contact with Miss Mo Jia, Su Yu understood that his current body was empty of strength, but he couldn't play it, if it wasn't for the Divine Soldier Experience Card he drew before, I am afraid he would have suffered a big loss.

Although the Yunlan Sect was the largest powerful sect in the Gama Empire, Su Yu didn't think that the Yunlan Sect's exercises were so strong, because compared to the entire Douqi Continent, the Yunlan Sect could only be regarded as a drop in the ocean.

Moreover, the system on his body is facing the heavens and all the worlds, among which there are many exercises that are more powerful than one Yunlan Sect, but now he has no exercises at all, and he doesn't have enough energy to draw lotteries, so he is also useless.

It didn't take long for Su Yu to appear in front of a huge attic, and he couldn't help but marvel slightly.

This loft is several feet tall and has three floors.

On the huge plaque on the attic on the lowest floor, there are three big characters inlaid with the ancient library hall of the dragon flying and the phoenix dance.

These three big characters exude the golden light of precipitation, and the huge wooden plaque is slightly yellow, with traces of wind and rain and vicissitudes of life.

This is the most important place of the Yunlan Sect, the Library Hall.

The fighting techniques collected by the Yunlan Sect for hundreds of years are all stored here, which is the guarantee of the Yunlan Sect's masters and prestige, and it is also the foundation for the Yunlan Sect to become the greatest strength of the Gama Empire.

As the most important place in the entire sect, the defense here is naturally extremely strict, although the defense does not seem to be so strict on the surface, but it is hidden in the darkness around the attic, and the glances that glance over from time to time make Su Yu feel inexplicably depressed.

"Whether there is a harvest or not, an hour will come out."

In front of the dark gate, a guard said with a blank face after checking the identification card in his hand.

Then, the door was pushed open.

In the library hall, the light is a little dim, and the soft light emanates from the luminous crystals inlaid around it, making the spacious pavilion deep and silent.

Entering the pavilion, there is a deep passage, and at the end of the passage, you can see a space with a glimmer of light.

This passage was not long, and Su Yu was like that space, and suddenly pieces of inky black bookshelves appeared in front of him, and those bookshelves were full of martial arts and fighting skills.

Su Yu walked into the nearest bookshelf and picked up a book of exercises, but at this moment, there was a prompt sound in his mind.

"If you find the Yellow Rank low-level Martial Fire Fighting Technique, do you exchange energy points?"

Unexpectedly, this opened the exchange of energy, Su Yu was in a good mood, after all, except for doing tasks, the system did not give other ways to earn energy.

At this time, Su Yu still hesitated, and directly agreed.

"Successfully exchanged, get 10 energy points."

As the three big characters of fire resistance on the surface of the exercise book in Su Yu's hand trembled slightly, and then there was a prompt sound of successful exchange by the system.

Su Yu's face froze, and he was even a little stunned, 10 points, what can 10 energy points do, he can't even reach the lowest lottery, he didn't expect that the energy points exchanged for this exercise book would be so small.

Maybe it's because the level of the exercises is too low!

Su Yu thought about it in his heart, and after opening this Yellow Rank low-level exercise Fire Resisting Technique, and found that the content in it had not changed, he put it back in the distance, and then picked up another exercise book from the side.

The familiar chime reappears.

"If you discover the Yellow Rank Intermediate Exercise Pyrotechnic Technique, do you exchange energy?"

Su Yu did not hesitate and directly agreed.

"Successfully exchanged, get 10 energy points."

There was no different prompt sound, which made Su Yu finally understand, I am afraid that this Yellow Order Exercise, no matter whether it is low or high, can only be exchanged for 10 energy points.

As for the higher Xuan Rank, the Earth Rank and the Heaven Tier, it is unknown.

Although this energy was scarce, when Su Yu looked around and saw the exercises and fighting skills on the rows of bookshelves, he suddenly smiled.

The water becomes a stream, and there is not much energy exchanged for a piece of exercise, but this is the library hall, which is the library of the Yunlan Sect, the strongest sect of the Gama Empire.

Su Yu smiled, put back the pyrotechnic recipe, and then picked up a booklet from the shelf.

"Found the Yellow Rank low-level fighting technique Four Elephant Palms, do you exchange energy?"

"Successfully exchanged, get 10 energy points."

"Discover the Yellow Rank low-level Exercise Tianmu Five Directions, do you exchange energy?"

"Successfully exchanged, get 10 energy points."

……

A steady stream of prompts sounded, representing that he put down the book of exercises and fighting skills he picked up, but a whole bookshelf came down, and the energy obtained from each book exchange was 10 points.

It also means that the martial arts fighting skills on this bookshelf are all below the Xuan Rank, but none of them exceed the Yellow Rank.

However, even if this is the case, all the martial arts fighting skills on the entire bookshelf have been exchanged, and the energy value in the system has become 1,200 points.

Seeing the energy value of getting rich in a short period of time, Su Yu was in a good mood, smiled slightly, and walked to the next bookshelf again.

And so it happened.

In the bookshelves on the first floor of the library hall, only Su Yu's figure was left standing under the bookshelf, and under the strange eyes of some scattered Yunlan Sect disciples, he quickly picked up a book of exercises, and then just opened it and quickly put it back in its original place.

It's just that other people don't know anything about it, so how can they understand Su Yu's abnormal behavior.

As for Su Yu, he picked up and put down the cheats one after another, and at the same time, the energy in the system in his mind also rose over and over again, making the smile on his face even bigger.

At this time, he had forgotten the original purpose of coming to this library hall, and everything was to frantically brush up the energy level.
