After flying for a while, Han Yu followed Wang Han to an inconspicuous building between the two hills.

The building is divided into five floors, and the whole body is shrouded in a layer of fiery red prohibition. Wang Han used the cyan leaves to break through the ban and enter the first floor, and saw three young monks sitting cross-legged by the bookshelves, some holding jade slips, and some talking softly, but their voices were very low.

Seeing that someone had broken the ban, those young disciples looked over and saw Wang Han standing up one after another to give a salute.

"I've seen the three elders!"

"Sit down, you all sit down, do whatever you want. Wang Tie, you came over to see Brother Han. Wang Han smiled at the young disciples, pressed his hand and motioned for them to sit down, and then said to a middle-aged man who was about fifty years old.

"Wang Tie is a monk stationed in the library and knows all the classics inside. ”

The middle-aged man had planned to retreat, but when he heard this, he walked over respectfully and saluted the two of them.

"Junior, Wang Tie, has seen the three elders, and he has seen the Han senior!"

The middle-aged man had a square face, his eyes were a little blank, he looked a little listless, and the fluctuations on his body were strong and weak, which Han Yu had also felt in one person. Seeing that this person didn't have much respect for Wang Han, he also had a guess in his heart.

"Wang Tie, Brother Han wants to read some books in the library pavilion, and if there are any requirements, he must try to meet them. Wang Han's face was obviously a little unnatural in the face of this person, and he said with a wry smile.

"Yes. The middle-aged monk glanced at Han Yu and saluted him.

"Hehe, I still have some things to do, Brother Han, please feel free. By the way, this is a magic weapon to break the ban in this building, and you can read all the books in the library. Wang Han handed the cyan leaf magic weapon to Han Yu just now, and said to him with a smile.

"Thank you, Brother Wang. Han Yu took it and said gratefully.

"Well, if there is anything, just let the disciple say it. Brother Han, the patriarch of this sect has a rule that all the books in it are not allowed to be taken out, please forgive me. Wang Han added.

"I'm also a member of the Wang family now, and I won't be polite if there's anything. Han Yu said a few words softly, Wang Han was overjoyed.

Immediately after that, he explained a few more words, and then politely said goodbye.

.....

After Wang Han escaped from the library pavilion, he did not return to his cave, but returned to Taoyuan.

The gray-clothed old man was standing under the tree at this time, Wang Han fell and clenched his fists and said, "Big brother, I have sent him to the library pavilion." ”

Wang Han was respectful to the old man from the bottom of his heart.

"That's good, I faintly have a sign of knotting, and having one more monk in the family who is in the late stage of foundation building is also an invisible deterrent, and those big and small families don't dare to stumble on my Wang family. The old man said with a sigh of relief.

"Do you want to marry Dan? The two magic weapons in the family to resist the thunder tribulation have not much power left, and you are a Nine Spirit Aperture, and it should be the Thirty-Nine Heavenly Tribulation, I'm afraid you won't be able to resist it." There are still three years left in the big set on Qingluo Island, let's see if you can buy one with your family savings, so that you can at least increase the possibility of crossing the thunder tribulation!" Wang Han said anxiously when he heard this.

"I have a vague feeling that if I don't try it now, I won't have a chance in this life. I have assigned the mundane matters of the family to them if something big happens. You should pay more attention to the newcomer Han Yu, and if he makes any changes, he will be strangled directly. The gray-clothed old man said, a hint of murder flashing in his eyes.

"Big brother, you're too worried, I saw this person once thirty years ago. Even the Chang family can't make such a far-reaching layout, and I've tried it a few times just now, and this person almost didn't agree to join my Wang family. Wang Han was startled and said.

"Well, that's good, but you should be careful, and don't let your guard down. The old man nodded and instructed again.

"Big brother, when will the ancestor come back?" Wang Han asked coldly after thinking about it.

"It's three or four years, seven or eight years. The ancestor is cautious by nature and will definitely return safely. The old man in gray said with a wry smile.

Unbeknownst to the two of them, their conversation had been overheard by a little ant.

When the two monks left, the ants flew slowly towards the library.

It circled the doorway, and was motionless on a tree not far from the building.

Han Yu was wandering around the first floor at this time, most of them were some experiences of Qi refining cultivators, and some tips for using spiritual power, he didn't dare to be interested in these.

"Brother Wang, can you introduce me to the Library Pavilion. Han Yu didn't rush up to the second floor, and said politely to the middle-aged man.

"Of course! The first floor to the third floor are some basic knowledge of cultivation, spiritual objects, minerals, and miscellaneous, and the fourth floor is some books from the foundation building period. It's not much use for you either. The fifth layer is some of the experiences of the ancestors of the past dynasties of this sect. Wang Tie said politely.

"Do you have a bibliography?" asked Han Yu with an eyebrow.

Wang Tie was stunned for a moment after hearing this, and handed over a list of books from the desk.

"I'm tired. Han Yu said politely, took a thick catalog, and then turned to leave.

Although Han Yu has read Qingyan's records and has a general understanding of the sea area, if he wants to understand the customs and geographical location of each island, that classic book is not enough.

Han Yu casually picked up a small pile of jade slips according to the guidance of the bibliography, and then walked directly towards the fifth floor.

There was a light curtain between the fourth and fifth floors, and Han Yu entered it after breaking it with the magic weapon in his hand.

On the fifth floor, there was only a lone solitary bookshelf, and there were only a dozen jade slips on it.

Han Yu didn't touch those classics, but found a jade slip about the location distribution and large and small forces of the various islands in the Nine Dragons Sea, and immersed his divine sense in it and checked it.

Han Yu lived in the Wang family's library for two months, and he looked through everything except for the cultivation classics of the Qi refining period, and felt that he had gained a lot. He also made a copy of some information about the sea area and the distribution of forces, planning to use it in case of emergency.

After reading a large number of classics, Han Yu finally had a general understanding of Jiulonghai, and was shocked by some of the rumors.

It turned out that in addition to cultivating, the high-level cultivators of the Nine Dragons Sea also needed to resist the once-in-a-century sea tide.

The so-called sea tide is a large-scale attack by some sea beasts on human monks.

According to a classic book, this sea area was originally the world of some fierce beasts. Because the pressure of the Ten Thousand Fierce Seas was too great, some high-level cultivators were sent to gain a foothold in this large sea area.

The human monks started by occupying a small desert island, and after 10,000 years of reproduction, they gained a foothold and kept the monsters out.

However, the demon beasts will naturally not give up, and there will be a small beast tide every hundred years, and a big beast tide every thousand years.

During the small beast tide, the human monks will summon the knot and some foundation building to resist, and the great beast tide once in a thousand years will be some old monsters in the primordial infant stage against some primordial infant demon beasts.

According to the records in the classics, there are few rumors of the fall of the monks of the Yudan period in the small beast tide once in a hundred years, and there are rumors of the fall of the Yuanying monks in the big beast tide once in a thousand years, and the deaths and injuries of the monks in the Jiedan and foundation building periods are even more tragic.
