I'm afraid that even if you sell thousands of Supreme Spirit Liquids, someone will want it. After all, there are very few spiritual array manuals in the world, and most of them are scattered in various places and incomplete.

So the book Ji Tianyu is holding now is definitely a thing comparable to a middle and high-level magic weapon.

Ji Tianyu quickly withdrew his thoughts and began to focus on studying the complete spiritual array manual in his hand.

It has to be said that the spiritual power fluctuations emitted after the two incomplete spiritual array manuals are much greater than before, and the spiritual array above is also more difficult.

Ji Tianyu browsed from beginning to end, his tightening brows getting deeper and deeper.

According to his estimate, the most difficult spiritual arrays on this level may have reached the level of intermediate spiritual arrays, and his current level is only a primary spiritual array master.

Ji Tianyu began to hesitate. He knew that if he wanted to get the recognition of the library, he would probably have to build the strongest spiritual array on it, but his strength was there again. For a moment, Ji Tianyu felt embarrassed.

After weighing and thinking, Ji Tianyu decided to try it. Even if he couldn't build the most difficult spiritual array on it, he wanted to build a complex spiritual array as much as possible.

Otherwise, he would have been in vain today.

After strengthening his belief, Ji Tianyu began to sit cross-legged and study it carefully.

Mu Qingshuang's side.

After she went upstairs, her reaction was exactly the same as Ji Tianyu, or even more so. Compared with Ji Tianyu's reaction, Mu Qingshuang was considered frightened.

She was so scared that she exclaimed, thinking that she was about to fall off after stepping on the air.

However, after a while, she was surprised to find that she was still in the place she had just arrived at. Mu Qingshuang slowly opened her eyes and stretched out one foot to test.

Then she closed her eyes and stepped on it, and made sure she would not fall. Then she breathed a sigh of relief and wiped the fine sweat from her forehead.

Immediately afterwards, a light shot towards Mu Qingshuang's direction, and Mu Qingshuang covered her eyes.

After getting used to the strong light, she slowly lowered her sleeves. What was suspended in front of her was a secret book, with the words "Sky Frost and Cold" written on it.

Mu Qingshuang was shocked. Isn’t this the secret she got from Xiaoqi and the others? How could it come out of her body? And she didn’t feel anything.

Mu Qingshuang immediately tried to find out that the cold air in the sky was still there. What was the secret book about the cold air in the sky in front of him?

Mu Qingshuang carefully stretched out her hands and took them over, then turned on its first page, and an ancient aura suddenly came to her face.

After reading the first page from beginning to end, Mu Qingshuang was even more surprised. The content on it was different from the first page of the Tianshuang cold air secret book in his body, but it was also obvious that they were the same secret technique.

Mu Qingshuang soon thought that the book in her hand was probably the second part of the secret book of the Sky Frost and Cold Qi in her body.

After all, she could see that the book in her hand was obviously much more difficult.

But she hadn't even learned the book in her body. Now the library handed it to her again what does it mean?

Mu Qingshuang's pupils shrank suddenly, and a thought arose in her mind.

Could it be that this library wants her to learn the second part of the frost and cold weather!

You should know that the first and second parts of the secrets like this are closely linked and step by step, and it is impossible to achieve them in one step. So if she wants to learn the second part of the frost and cold weather, she must understand all the contents of the first part.

Even if you don’t need to learn everything, you have to understand everything. Otherwise, if you want to practice the second part of the Frost and Cold Qi, you will be a fool.

Mu Qingshuang swallowed her throat and was frightened by the request of the library. She was basically the one who had just started practicing the cold weather in the sky, so she had to learn the contents of the second part directly...

To be honest, Mu Qingshuang wanted to give up because in her opinion, this was basically a fantasy and impossible task, at least she felt that she could not do it herself.

But just when she wanted to give up, a familiar face appeared in her mind, and it was Ji Tianyu.

She knew that if Ji Tianyu encountered such difficulties, he would not want to give up, and what reason would he have to give up?

Mu Qingshuang regained her spirits, regained her confidence, and looked firmly at the second part of the Tianshuang Cold Qi in front of her.

Then she took out the first part from her own ruins, because if she wanted to understand the contents in the second part, she had to thoroughly digest everything in the first part.

Mu Qingshuang began to concentrate on her understanding, understand the ancient Chinese texts that were difficult to read and felt them with her heart.

Time passed by the two of them's tireless practice, but when they were in the scene, they seemed to have forgotten the time, where they were, the purpose of their journey, and focused on their own practice.

Half a day passed quickly, but there was still no movement in the library, it was pitch black.

Half a day passed, and there was still no movement. The two of them were still sitting cross-legged in the original place.

On the afternoon of the second day, Ji Tianyu suddenly opened his eyes, waved his sleeves and began to condense the talisman. After more than a day of insight, he seemed to have some ideas, but as for whether he could succeed at one time, he was really not sure.

But he will do his best to build a complete spiritual array seriously, and strive for one-time success. After all, the fewer the times, the more you have the chance to gain recognition from the library.

After a while, dense beads of sweat began to emerge from Ji Tianyu's forehead.

However, he was not under pressure, but entirely caused by tension.

A tiger-shaped frame was finally constructed with Ji Tianyu's efforts, but this was just the first step. It also required to add complex lines to make the power of this spiritual array even more powerful.

Suddenly, a light spot suddenly dimmed, Ji Tianyu's pupils shrank suddenly, and he immediately used his spiritual power to temporarily stabilize the entire spiritual array framework.
