As soon as Lu Ran pushed open the alchemist's door, she found that she had stepped on something soft, she was startled, jumped back, and saw a person lying on the ground, it was Zhao Danshen.

In addition to this, there were many books thrown on the ground, which had been turned in a mess, and it seemed that he had been here all night.

Not only Zhao Danshen was there, but Li Moxuan was also there, and he was picking up the books that had been lost on the ground and putting them back on the shelves.

Zhao Danshen stood up in a daze and said to Lu Ran: "Oh, you female doll looks very thin, but if you step on this foot, my old life is almost gone." ”

Lu Ran stuck out her tongue embarrassedly, she was really sorry, she was in too much of a hurry, so she didn't pay attention to the ground.

But what was he doing, and what were so many books for?

"Didn't I help you refine the Nine Turns Divine Pill successfully, so I just looked to see if there were any relevant records in the previous ancient books, who knows if I searched for a night, and I couldn't find anything." Zhao Danshen said while rubbing his waist.

I didn't expect the dignified Danshen to be so concerned about her own affairs, Lu Ran was still very moved, and she thanked Zhao Danshen.

Zhao Danshen waved his hand: "I'm not all for you, after all, your man is my apprentice, how can I, as a master, do I have to do a little bit of my best." ”

This title made Lu Ranqiao blush, but she didn't say anything to refute it.

However, even though Zhao Danshen's collection of books here was already very complete, for a whole night, Zhao Danshen did not find any records related to the Nine Turns Divine Pill.

When she was in the Sunset Country before, Lu Ran also read a lot of classics with the help of the princess, and the only information she knew was that the dean had helped the king refine the pill, but because the king was unwilling to refine the essence of the evil in the end, the matter was not resolved, and there was no specific record of refining the pill in the classics.

Is it true that there is no clue at all?

Just when Lu Ran was a little depressed, Lin Danshen walked in, and unlike Lu Ran, she looked refreshed.

"I came up with an idea." Lin Danshen said with great interest, "Do you remember those codexes left by Emperor Dan before?" ”

Zhao Danshen showed a thoughtful expression, and then slapped his thigh, yes, Codex!

Five hundred years ago, after the dean disappeared from the Genting Continent, all his things were sealed in the palace of the Tianchen King, at that time, Lin Danshen had not yet cultivated to the Dan Sheng, but his attainments in Xuanwu had reached the Martial God, and he had the qualifications to enter the Tianxuan Academy, so she once visited the Dan Emperor who was still a teacher of the Tianxuan Academy at that time.

She knew that the dean had a codex that might record the tricks of how to refine the Nine Turns Divine Pill.

"Really!" Lu Ran felt as if she had seen a glimmer of hope, and she happily patted her clothes, preparing to enter the palace once.

The feeling of entering the palace for the second time was a little different from the first time, and this time Lu Ran was more anxious.

It's just that this time is more thrilling than last time, because although Zhao Danshen can take Lu Ran into the alchemy room, there is no way to take Lu Ran to find the Codex, and in the palace, Zhao Danshen is not every place where he can enter and exit at will.

"Be careful, I'll be waiting for you in the alchemy room, you have to remember, if the soldiers find out, just say that I'm lost with you, you know?" Zhao Danshen commanded.

Lu Ran nodded, and carefully avoided the soldier to prepare to find the Codex.

The Tianchen King's Palace is very large, and even Zhao Danshen doesn't know the specific location of the Codex, so he can only guess that it should be in a place like the Palace Library.

The soldiers in the palace patrolled very densely, and it was actually quite difficult to avoid them, but fortunately, Lu Ran was a Xuanwu master, so it would be easier to dodge them when using the body method.

She cautiously jumped onto the wall, then leaned down and walked down the ridge.

Just as he was about to jump down, a pair of soldiers passed by, Lu Ran quickly held his breath, and hung one hand on the eaves, like a little monkey.

It's really scary here.

Lu Ran came to the library pavilion and slowly pushed open the door, this library pavilion is very large, larger than the library pavilion of Baiyun Academy, perhaps because everyone thinks that there is a layer of enchantment outside the palace that no one will be able to enter, so no new enchantment has been found in the interior of the palace for the time being.

Because the dean is absolutely not allowed to be mentioned in the Genting Continent, then the things he left behind should also be forbidden, Lu Ran thought, he still had to find out if there were any secret rooms, secret grids and the like here.

Since it is a secret room, it is naturally not very easy to find out, Lu Randong looked at the west, and found nothing.

She was not discouraged and let out of her sleeve.

"Your nose is smarter, and you smell the smell of people in this place." Lu Ran said.

Tuan Tuan did as he was told, sniffing carefully on the floor of the library before finally stopping in front of a wall.

The smell of the rest of the place here is very light, only here is very strong, as if people often stand here, and the mysterious beast is more sensitive to the moving air than humans, Tuan Tuan can feel that this place looks impermeable, but in fact there is a slight air movement, just below the crack in the door.

Lu Ran lay on the ground, and sure enough, he felt a little wind, if he didn't feel it carefully, he wouldn't feel it at all.

"Let me see." Lu Ran motioned for Tuan Tuan to get out of the way, and then groped for the door.

Strange, there don't seem to be any mechanisms around here, so how did this door open?

Lu Ran looked at the bookshelf and found that there was something wrong with the books on it, obviously most of them were books related to history, but there was one book about medicinal herbs.

On closer inspection, the edges of the book show some signs of wear and tear, as if they are often looked at, while the others are very new.

She stood on tiptoe, picked up the book, and opened it, but it was all blank.

Lu Ran just thought about what this meant, but when she closed the book, she found that everything in front of her had changed, and she was no longer in the library cabinet.

She closed the book, and the book disappeared, and Lu Ran touched the wall, which was the same texture as the wall of the Library Pavilion, which means that she was already in the secret room of the Library Pavilion?

That book was supposed to be a teleportation array.

Now that the secret room has been found, maybe the dean's codex is here, Lu Ran casually took a small pebble and threw it on the ground, the pebble rolled out with a grunt, and finally the sound disappeared into the darkness ahead.

It seems that this place is very deep, Lu Ran doesn't know if there will be any mechanism ahead, and she doesn't know what is hidden here, she only knows that she has no way out, and the only choice is to move forward.
