After saying goodbye to Su Lingwei, Ye Lin returned to the practice room in the courtyard of Qingyao Palace.

As soon as he came back, Ye Lin took out the Qiankun bag given by his master, containing thousands of precious books. Then, with a thought, thousands of jade slips in the Qiankun bag appeared in front of Ye Lin.

With a wave of his sleeves, all the jade slips turned into spiritual light and penetrated into the ancient ring. At the same time, Ye Lin's consciousness incarnation also appeared at the door of the Ancient Ring Library.

Now Ye Lin’s library is dozens of feet high, extremely grand, divided into many layers. The first layer stores basic knowledge books and some entertainment travel notes, and all literate spirit insects can borrow.

From the second level, many low-level exercises and some professional knowledge were stored, which required spiritual insects who graduated from secondary schools to borrow.

The higher the number of layers, the higher the level of the exercises, the more profound the professional knowledge becomes, and the more demanding the conditions for borrowing books.

In fact, Ye Lin can also let the spirit insects copy many similar books. There is no threshold for all spirit insects to borrow, but he did not do so.

Because this makes knowledge cheap.

And the cheaper things are, the less likely they are to be cherished and respected.

Ye Lin sets that each floor has an entry threshold, which will make the spirit insects entering the high-rise library feel proud, glorious, and accomplishment. They want to study harder and enter the next library to read it.

Books improve one's own abilities to form a virtuous cycle.

It is precisely because of Ye Lin's strategy that the Library now has become a holy place in the ancient ring space and a place where most spiritual insects yearn for and respect them.

On the first floor of the library, different kinds of spiritual insects come and go, like flowing water.

"Wow, the master is here!"

"Hello, Master!"

"Master, please do it!"

“Master is great!”

Ye Lin smiled kindly, nodded to the spirit insects entering and leaving the library, then reached out and touched the heads of the passing spirit insects casually.

"Master, Master, I just saw a lot of jade slips flying into the last two floors of the library. Are they all very profound knowledge?"

Ye Lin nodded.

Suddenly, the spirit insects passing by looked up at the top of the tower, their eyes showing a fever.

"In the future, I must step into the last floor of the library, be familiar with astronomy, geography, five elements, yin and yang, and become a great scholar in the foundation-building stage respected by insects!"

"Student, I think you should consider whether you can pass the secondary school graduation exam in front of you..."

When Ye Lin saw these little guys with hot eyes heard the word "graduation exam", he looked frowning and laughed a little.

"Fortunately, I haven't become a scholar who has won the exam in my life, so it's better to practice immortality."

Soon, Ye Lin used his divine thoughts to inform all the spiritual insects of the foundation-building stage and informed him of the news that a large number of advanced books were placed in the library. Before Ye Lin could leave, several shocking birds were flying towards him.

The ones who are most happy about this are naturally Xiaoshu and Xiaodan, such spiritual insects with profound attainments in professional fields.

Ye Lin called Xiaodan before he entered the library.

"Xiao Dan, let's take a look at this pill recipe. How much hope is there for completion at present?"

As he said that, a flash of inspiration appeared in Ye Lin's hand, and the "Insect Emperor Dan Dan" that the master gave him this morning. After Xiao Dan took the jade slip, he fell into a long silence, obviously reading it.

The contents of the jade slip.

After Ye Lin waited for about a cup of tea, Xiao Dan came to his senses and his eyes became quite horrified.

"Master, this is an ancient pill recipe. This insect emperor pill has the terrible effect of quickly improving the spiritual insect cultivation, which greatly increases the probability of forward mutation of the spirit insects!"

Ye Lin was delighted when he heard this.

At present, the way for spirit insects to improve their cultivation is quite primitive, that is, meditate and practice hard. Only the main fighting spirit insects in the Foundation Establishment stage can occasionally eat the foundation-building pill refined by mutant spirit grass to improve their cultivation.

However, the Foundation Establishment Pill is still a relatively scarce thing in Ye Lin. There are still many spiritual insects waiting for promotion, which is not enough.

The foundation-building pills that Ye Lin gave to Elder Sun were all made by him gritting his teeth and spending a large amount of spirit stones to urge the alchemy spirit insects to rush to refine them.

Moreover, although this foundation-building pill has the effect of diligent cultivation, it is not a pill specifically used for diligent cultivation.

If the Insect Emperor Pill can be refined, this gap can be filled.

Xiao Dan said again: "But the master cannot be too optimistic. This ancient pill recipe has existed in the world for many years. Many of the spiritual herbs and medicines in it are extremely difficult to find. Some of the spiritual herbs have even become extinct, and some of them have been

The grass has even changed its name, which will hinder the completion of the pill recipe."

"Also, this should be a very high-level elixir. The minimum number of spiritual herbs and elixirs required is more than 5,000 years. It is difficult to understand the pharmacology of Yi Xiaodan's current elixir practice.

It is expected that the alchemy will have to study hard for at least one or two years before it can be possible to comprehend this alchemy recipe."

"Only by thoroughly understanding the pharmacological principles of the elixir recipe, you can try to complete the elixir recipe."

Ye Lin nodded slightly when he heard this, and then smiled and said, "It's okay, don't rush for a moment. The more advanced the pill, the more effective it will be on our future. This is a good thing."

Xiaodan also nodded obediently, and then couldn't wait to say, "Master, Xiaodan is going to read a book and learn new alchemy knowledge!"

"Go!"

After understanding the difficulty of completing and refining the "Insect Emperor Pill", Ye Lin's consciousness immediately withdrew from the ancient ring space...

Two days later at noon.

Under the escort of Elder Sun and his senior sister, Ye Lin flew from the Spirit Beast Peak into the forbidden area of ​​Taixuan Peak, and secretly walked from a secret room to a hall located in the belly of the mountain.

On the platform in the center of this hall, there is a small teleportation array that is shining and mysterious.

This teleportation array should be the ancient teleportation array that the Zhengdao Alliance has recently spent a huge cost to repair, leading to the outside world.

Even Ye Lin did not expect that this ancient teleportation array would be built in the forbidden area of ​​Taixuan Gate. No wonder the righteous alliance was not afraid of the Demon Alliance destroying the ancient teleportation array and preventing Ye Lin from going to the outside world.

Why does the Taixuan Gate Guardian exist in an ancient teleportation array leading to the outside world?

Later, why did this ancient teleportation array not open or even become incomplete?

There must be many secrets of long history hidden in this, but this is not something Ye Lin should care about.

Before Ye Lin walked into the teleportation secret room, three Nascent Soul cultivators sat cross-legged in the secret room, all of whom Ye Lin knew, namely the Fairy Youquan wearing a palace outfit, the Scholar Taixuan holding a book, and
Chapter completed!
