A complexly constructed purple divine seal with a dragon head and a phoenix tail may have hundreds of millions of different interpretations due to its combination with other divine seals. Only a very small number of people can recite the classics recorded in this divine seal naturally and fluently.

The Fish-Dragon Divine Seal is much simpler. A Fish-Dragon Divine Seal may only have three or five meanings and is more suitable for daily writing and note-taking.

To use a not very appropriate metaphor, the Dragon Head and Phoenix Tail Purple Seal is a national treasure, as high and mighty as the Nine Cauldrons, but normal people have no use for such a high-end thing in their daily lives; and the Fish Dragon Seal is a utensil like pottery jars and porcelain plates, which are indispensable for daily use.

On the plaque, the two ancient and heavy fish-dragon seals with purple aura rising from them were marked with the word "Dan Palace".

If we extend this idea, the meanings of these two divine chapters are equivalent to that this is the 'Alchemy Hall', or a hall for storing elixirs, or perhaps this is the place where a certain alchemy master teaches the art of alchemy on a daily basis.

What the meaning of these two divine seals here is can only be discovered by Chu Tian himself.

The two metal puppets strode towards the collapsed gate of the Dan Palace. They leaped into the air, crossed the threshold that was twenty or thirty feet high, and stood on the threshold that was ten feet wide.

After staying for a while, Chu Tian saw that the two metal puppets were safe and sound, so he also flew up and landed gently on the threshold.

In the huge Dan Palace, on the left were rows of bookshelves carved from transparent crystals. The rows of bookshelves, which were five hundred feet high, were neatly arranged without any dust from the years.

Standing here in Chutian, you can see rows of bookshelves that stretch as far as the eye can see. There are at least thousands of rows of bookshelves standing there quietly.

On the bookshelf, there are many large and small classics arranged in an orderly manner, including scrolls, books, jade discs, jade books, and even clusters of light shining with strange light.

Countless years passed, and a layer of purple-red halo visible to the naked eye covered these bookshelves, emitting powerful fluctuations that made Chu Tian frightened.

Obviously, this is an extremely powerful defensive barrier, specially used to protect these bookshelves and the books on them. It is precisely because of this powerful barrier that these books are still well preserved after countless years.

"Wow! So many books!" Rat Lord subconsciously began to rub his two front paws, with an extremely sharp light flashing in his eyes: "Empty them, empty them, you must empty them! The ancestor of your Chu family in Qizhou said it well, descendants of the Chu family, you must read more books, there are mountains of gold in books, there are seas of silver in books, there are countless beauties in books!"

Chu Tian quickly glanced at Shu Ye. He was very curious about what kind of person the Chu ancestor who saved Shu Ye back then was to be able to say such words.

"Empty it, I also want to, but it depends on whether we have the ability to do so!" Chu Tian took out a piece of Yanyu Crystal he picked up on the road and gently threw it to the nearest bookshelf.

"Swish", Yan Yujing was still more than ten feet away from the bookshelf when it inexplicably turned into a wisp of green smoke.

Chu Tian and Shu Ye gasped at the same time. Although the Flame Jade Crystal is a material of fire attribute, it contains a huge amount of extremely pure spiritual essence of heaven and earth. Its texture is extremely hard, and it is difficult for ordinary spiritual weapons of the Ascension Realm to damage it in the slightest. It must be smelted and forged with some special techniques.

Such a hard Flame Jade Crystal was so easily turned into a wisp of green smoke by the defensive restriction. Chu Tian didn't dare to imagine what would happen to him if he accidentally touched it.

"That doesn't make sense!" Lord Rat stuffed the tail into his mouth and bit it hard. The whiskers on his face drooped down and his expression became very ugly: "Everyone is dead, but you are still holding on to these treasures... misers are really hateful to the extreme!"

Chu Tian stared at the bookshelves in a daze for a while, shook his head, and his eyes suddenly lit up. He saw on the right side of the hall, in a vast space, nine dragon head fire spouts extending from the ground, and nine alchemy furnaces surrounded by purple air!

Compared to the Zi Yang Furnace that Chu Tian is using now, which he bought from Huanling Pavilion, the appearance and the aura emitted by these nine furnaces are at least a thousand or even ten thousand times better than that of the Zi Yang Furnace!

The nine alchemy furnaces are about three hundred feet high, with three legs at the bottom. The furnace bodies are round and glowing with purple light as if they are translucent. There are three circular fire doors on the furnace bodies, through which you can see the pure golden flames whistling and swirling inside the furnaces.

The nine alchemy furnaces were obviously a set of treasures. On the first furnace, there were nine flying dragons circling; on the second furnace, there were nine phoenixes dancing wildly; on the third furnace, there were nine unicorns stepping on the mountain; on the fourth furnace, there were actually nine nine-tailed foxes worshiping the moon...

The patterns on the nine alchemy furnaces are different. There are dragons, phoenixes, unicorns, and celestial foxes, all of which are the most noble and powerful true spirits in the world according to legend!

In the pill furnace closest to Chu Tian, ​​where the nine dragons were entangled, through the round fire door, one could see clusters of dazzling lights flashing in the golden flames. These lights were flashing with colorful rays of light, and occasionally when the rays of light were rotating, one could see round pills circling and dancing rapidly in the golden flames.

"There's a pill!" Rat Master took a deep breath.

"The question is, after so many years, the pill has not been refined into ash by this flame. Do you dare to eat it?" Chu Tian looked at the pill looming in the furnace, swallowed his saliva, and asked Master Shu in a very tangled way: "Do you dare to eat it?"

Whether it was in the Ziyin inheritance or in the Taiyi Qingling Sect's alchemy classics, the longest elixir that took the longest time to make was only 360 years. Even the best elixir, if the time to make it was missed, would be turned into ashes or produce an inexplicable elixir poison. In short, it would not be a good result.

And how many millions of three hundred and sixty years has this Qiqiao Heavenly Palace existed?

"It's hard to say!" The hairs that had just grown on Master Rat's body stood up one by one. He gritted his teeth and said sternly, "Master Rat likes this... Let's find a way to take it out first, and Master Rat will just take a bite. Master Rat is lucky and won't die! Hey, maybe it's a good pill?"

A strand of sparkling saliva flowed from the corner of Shu Ye's mouth. Like Chu Tian, ​​he stared at the nine alchemy furnaces without taking his eyes off them.

However, Chu Tian was staring at the nine alchemy furnaces themselves, while Shu Ye was staring at the elixirs inside the furnaces.

After a long time, Chu Tiancai sighed and looked towards the center of the hall.

Obviously, this Alchemy Hall was the place where the original owner made alchemy, read books and gave lectures. There was a bookshelf on the left, an alchemy furnace on the right, and in the middle, thousands of smooth and moist cushions made of cold jade were neatly stacked.

In front of these cushions, a purple gas descended from the sky, covering a high platform.

There was a futon on the high platform, and in front of it was a small desk with an incense burner, a jade chime, a ruler, and more than a dozen huge jade scrolls that were more than twenty feet long!

Chu Tian's eyes suddenly lit up, Danshu!

Moreover, there seems to be no restrictions on this platform.
