Milan's voice spread, and suddenly more than two hundred Radiant Dragons who had been waiting in the square outside for a long time rose into the air and flew towards the Zenith Library, followed by Zhang Ye and Lil.

The Zenith Library is huge.

Many things need to be maintained by magic circles, such as special shelves for storing magic books, or defensive magic circles to protect libraries.

There are thousands of large and small magic arrays, so it takes three days for the magic array to be inspected, and the library will be emptied during these three days, and no one will be allowed to enter.

And Zhang Ye has to find out all the hidden black magic in three days.

The area of the library is really large, with a collection of more than 100 million books, and it is undoubtedly a needle in a haystack to find hidden black magic in such a large area, but it is actually a piece of cake for Zhang Ye, who has a system.

Don't say three days, I'm afraid three hours is enough!

It's just that Zhang Ye wishes for a little longer, because in this way, he can take this opportunity to go to a higher level and learn more high-level magic.

Of course, there are records of high-level magic in ordinary books, but most of them are incomplete or incorrect.

The more high-level magic is, the more it cannot be recorded in ordinary books, which is why Zhang Ye did not learn ninth-order or saint-level magic.

It's not that he doesn't want to learn, it's that there are too many mistakes in ninth-order or saint-rank magic recorded only in ordinary books, and Zhang Ye even saw a saint-rank spell called [Archangel Judgment], and it took ten years to analyze it!

It's just that, Zhang Ye can't afford to wait.

However, the high-level magic recorded in the magic book is different, because the magic recorded in the magic book is extremely detailed.

Moreover, there is also a specific magic power to guide, so that the analysis time required by Zhang Ye is only half of the analysis time of the original level!

In other words, it originally took a year to parse a Saint-level magic, but it only took half a year after analyzing it with a magic book, which is so fast!

The benefits of magic books Zhang Ye only realized in the past few days.

Upon arriving at the Zenith Library, Milan directly issued the mission.

"Three groups inspect layers 1 to 3, two groups inspect floors 4 to 6, one group inspects floors 7 to 8, and a special group inspects the core circle ......"

One order after another was issued in an orderly manner, and all the Radiant Dragon Clans took action, and then Milan flew directly to Zhang Ye and said:

"Lil, from now on, you follow Zhang Ye and assist him. ”

"Okay. ”

"Zhang Ye, the next task is very arduous, you must ensure that you find all the hidden black magic, can you do it?"

"No problem at all!"

Zhang Ye patted his chest and said, since entering the library, the system has already scanned out all the hidden black magic, because it has been scanned last time, and this time it only needs to be marked.

"Okay, let's do it, I'm going to check the magic array on the ninth layer, pay more attention to yourself. With that, Lil flew towards the upper echelons of the library.

"Let's start, Senior Brother Zhang Ye. Lildo.

"Hmm. Zhang Ye nodded, took the magic pen that Milan gave him and began to make marks.

"Water Magic, p. 34. ”

"The thirteenth of the Thirty-Three Powerful Wood Magics. ”

"The thirty-seventh type of "Fifty-four Kinds of Magic That Metallic Mages Must Learn". ”

“......”

Lier's whole person was stunned, and she saw Zhang Ye writing hard, as if she had already sensed it.

Walking past a bookshelf and picking up one of them directly, and then marking the cover of the book, Zhang Ye could find several books with hidden black magic in almost a minute.

The speed is simply speechless, this is because it takes time to get the book, otherwise Zhang Ye can be faster.

The magic pen given by Milan is invisible, and can only be revealed when specific magic is used, which is very secretive, so Zhang Ye doesn't have to worry about soiling the book and writes casually.

"Is [Water Breathing] also a hidden black magic?" Suddenly, Liel couldn't help but ask when she saw the magic name of a book marked by Zhang Ye.

"Well, although this water breath technique allows people to breathe freely underwater, and can also isolate the pressure of deep water, in fact, its original magic is black magic [Water Suffocation]. ”

"Normally, as long as you have magic, you can maintain the Breath of Water, but if you reach a certain limit, or if certain conditions ......"

"The effect of the Water Breath Technique will be reversed in an instant, closing the muscles and veins, the magic power cannot work, even the basic magic protection body can't be done, no matter what magic can't be released, if you are still in the water at this time, what will happen?"

Zhang Ye turned his head to look at Lier and said.

"Uh......" Liel froze for a moment, then asked, "What limit? What specific conditions?"

"The depth of the dive is more than 10,000 meters, or the mana reserve is less than 30%. ”

Zhang Ye said casually, but suddenly he found that Lil's face was very bad, very dark, and she looked very frightened.

"What's wrong?" Zhang Ye asked suspiciously.

"Water Miracles...... Forty-two people are missing...... ......I see," Liel muttered, her face darker and darker, and finally her eyes turned red and pearly tears dripped down.

"Eh, what's wrong?" Seeing that Liel suddenly cried, Zhang Ye was blinded.

"So that's the case!" Lil suddenly raised her head and looked at Zhang Ye:

"Before, the elders of the academy led an expedition team to explore the water spirit miracle, a total of seventy-four people, half of them were from our Radiant Dragon Clan, but...... Only twelve people came back......"

"None of the Radiant Dragons who went have returned!" Lil's emotions seemed a little excited.

"I was still wondering why this was happening, and I thought it was just because the miracle was too dangerous...... There is no land in the Water Spirit Miracle, only the ocean and the endless sea. ”

"There is a palace of the god of water in the miracle, just at the bottom of the sea at a depth of 10,000 meters, in order to explore the palace of the god of water, each of the people who went forward has learned the art of water breathing, and each of them has mastered it perfectly, their strength is very strong, but I didn't expect it to ......"

"I finally understand ...... now"

Speaking of this, Zhang Ye almost understood, and his heart was cold.

If that's what Lil says, it's really desperate.

The expedition team dived into the deep sea after entering the water spirit miracle, but when diving to the bottom of the sea at a depth of 10,000 meters, the water breath suddenly lost its effect, and then was enveloped by a huge water pressure.

There was no air or light, and at the same time, the magic power in his body could not function, and he couldn't even ask for help and save himself, that feeling of despair, Zhang Ye didn't even dare to think about it.

And it seems that it is still premeditated, otherwise how can it be so good that the limit of the water breath technique is 10,000 meters?

Why did the people who entered the water spirit miracle learn the art of water breathing?

Although he was not sure, Zhang Ye still boldly guessed that someone deliberately did this to let everyone learn the water breathing technique, and the purpose was to kill all the members of the expedition, but for some reason they let the twelve people come back alive.

Or maybe the murderer was one of the twelve, or ...... Both?

This thought made Zhang Ye shudder a little.

That murderer's heart can be punished!

Emma, this academy is such a mess! I'm so scared......

It's better to have the Warcraft Mountain Range, or Tomorrow City, or Dragon Castle, or Red ......

"Original...... That's how my brother died......" Lil's tears kept falling, and her shoulders trembled, which was pitiful.

“...... The dead are gone, and the living mourn in silence. ”

Zhang Ye's heart softened, gently patted Lier's back to comfort her, and said:

"And I think it's someone behind the scenes, Sister Lil, what you have to do is not cry, but to find out the truth, and then find out who is behind the scenes, and avenge your brother. ”

"Avenge my brother......" Liel raised her head and looked at Zhang Ye's face, then her gaze gradually became firm, and she nodded vigorously:

"Hmm!"

......
