Qi Lianhua took the small black stone and looked at it for a while, and then said:

"Senior Brother Lu, I'm sorry, forgive me for being short-sighted, I really can't see the mystery of this black stone tablet, but the language on this black stone tablet should be some kind of ancient language. ”

Lu Jin felt a wave of disappointment in his heart, if he didn't even know Qi Lianhua, he really didn't know who to ask.

It would not be good if others watched this small black stone flake, or it reached the ears of Tianji Pavilion!

After all, his first small black stone chip was obtained from Xiao Jing.

"But...... Senior Brother Lu, don't be sad, although I can't see it, but there is a place to store ancient books in the Law Enforcement Hall, and you can look up the information there. ”

As if he suddenly remembered something, Qi Lianhua suddenly spoke.

"Where to store ancient books?"

Lu Jin muttered after listening to Qi Lianhua's words.

"Yes, the ancient book library of our Law Enforcement Hall was founded at the same time as the arsenal, but the ancient book library has been forced to close due to the lack of interest, but I can let Wang Ming take you there, maybe you will gain something. ”

Qi Lianhua's words echoed in his mind, and Lu Jin followed Wang Ming to the ancient book library.

The Ancient Books Repository is different from the huge Law Enforcement Hall Arsenal, and the scale is not large, just next to the Law Enforcement Hall Arsenal.

Wang Ming opened the rusty lock, then stood outside and said to Lu Jin:

"Lord Lu, just go in and watch, I'll help you guard outside!"

After Lu Jin thanked Wang Ming, he walked into the ancient book library.

Due to the neglect of this ancient book storehouse, the room is covered with cobwebs and thick dust, but fortunately there are no rats.

Otherwise, the room will be full of books!

Books with a heavy sense of history are placed in huge bookcases.

Among them, there are all kinds of anecdotes, gold and stone encyclopedia, as well as the development history and geography and water conservancy of the Jiuxiao Continent.

The smell of wine is also afraid of deep alleys, it's a pity that there are so many good books!

Ever since the Nine Heavens Continent began to set off a craze for cultivation, it has completely emphasized martial arts and light literature.

People regard warriors as real powerhouses, and literati as powerless waste!

That's why there is such a stark opposition between the arsenal and the ancient book library.

After Lu Jin sighed, he quickly searched for information related to the small black stone chips, and finally, a book called the secret of the ancient man kingdom caught Lu Jin's attention.

The kingdom of Kuman, standing alone in the desert of yellow sand, is said to be the origin of Queen Medusa.

The kingdom of Kuman is divided into three major cities, namely the City of Enchantment, the City of Money, and the City of Lost.

The city of charm is full of snake women, bewitching and beautiful, full of charm, and at the same time ruthless.

Many of the men who walked into the City of Enchantment either died unexpectedly, or were fascinated by the women of the snake clan and gave up the path of cultivation.

The City of Money is the largest market for goods in the desert, and unlike most of the cities in the Nine Heavens Continent that turn a blind eye to transactions, all transactions in the City of Money are fair and just.

If one party robs or plays a scoundrel, it will be ruthlessly thrown into the snake cave by the city of money, and will be bitten to death by ten thousand snakes.

There will also be a lot of rare and rare trading items, so many warriors are willing to travel thousands of miles to the City of Money.

The Lost City of Kuman is a special existence, where strength reigns supreme and there are no laws or constraints.

Words such as burning, killing, looting, and eating the jungle can be seen almost everywhere in the Lost City!

Therefore, most of the people who have lived in the Lost City for a long time are the evil madmen of the Nine Heavens Continent!

Underneath the entire city of the Lost City is a huge mechanism that moves with the turn of the quicksand.

Therefore, even when several major sects on the Nine Heavens Continent united to exterminate the Lost City, they all gave up because they couldn't predict the location of the Lost City.

After Lu Jin finished reading this book, he didn't find a way to enter the Lost City in the book.

Although he didn't know how to enter the Lost City, Lu Jin also understood the origin of the small black stone chips.

Where there is life, there is hope!

A world without rules and constraints, a world where the jungle eats the jungle!

He believed that his future self had reached that level when he entered the Lost City!

Closing the book, Lu Jin took out the small black stone chip and grinded it, and then picked up a book of gold and stone that he had just seen.

This book is several times thicker than the secrets of the Kuman Kingdom, and there are pictures of various gold and silver minerals on it.

Lu Jin rummaged through and found an ore called obsidian.

Obsidian, mined in the northeast of the Jiuxiao Continent, is scarce and rare, and is mostly used to make jade slips.

A simple introduction and a picture of obsidian caused turmoil in Lu Jin's heart!

Could it be that the small black stone chip in his hand is a jade slip?!

The method of making jade slips has been lost for a long time, and most of the jade slips seen now are handed down from ancient times, and most of them record the secret books and ideas of ancient cultivators.

There were even people who found an ancient cultivator's cave mansion in the jade slips!

When Lu Jin learned that the small black stone chip in his hand was most likely a jade slip left by an ancient cultivator, he knew that he had picked up a big treasure!

Fortunately, the old man in the martial arts exchange bazaar did not come to the ancient book library of the Law Enforcement Palace, so he would have this opportunity!

After knowing the true identity of the small black stone shard, Lu Jin closed the book and walked out of the ancient book library.

It was not yet noon when I entered the ancient book library, and now that I came out, the sun had already set in the west.

Wang Ming leaned against the door and fell asleep in the boring waiting, saliva flowing.

"Brother Wang, I'm out. “

Lu Jin stretched out his hand and shook Wang Ming, waking him up from his sweet dream.

"Ah...... Ah, Lord Lu, you're out, I'm sorry, I accidentally took a nap!"

Wang Ming stood up, quickly wiped the saliva from the corner of his mouth, and took out the key to relock the door of the ancient book library.

"I wonder if Lord Lu has found what he wants?"

On the way back to the backyard, Wang Ming asked curiously.

"Unfortunately, no. ”

Lu Jin shook his head, with an extremely disappointed expression on his face.

"It's okay, it's okay, as long as Lord Lu looks for it carefully, he will find it one day. ”

Wang Ming hurriedly comforted Lu Jin and said.

The small black stone flakes are probably the matter of the ancient jade jian, and Lu Jin doesn't want to tell anyone, even Qi Lianhua!

After all, man's greed is unpredictable, and he doesn't want to gamble with his life!

Back in the room, Lu Jin began to clean up the things that had been knocked over in the small bedroom when he was taking the pill today.
