Knowledge is expensive.

This is especially true when it comes to knowledge of strength.

The crowd floated to the floor, and Mango spoke, "So, this man is still a magician?"

"A necromancer, to be exact. Cangsu's words immediately attracted everyone's attention.

Abarsu walked over to the circular desk.

In front of him was the huge magic book.

Compared to the books on the shelves, the magic book was half a man's height, at least the width of an adult's forearm. If it is opened, it will naturally be wider.

As soon as Cangsu saw the magic book, his eyes were drawn to it.

The magic book is the thickness of a fist, and the cover is pitch black, but the corners, bones, and pages of the book are made of bone. The bones were so white that they were oozing. The whole book has been giving off an eerie chill.

Cangsu watched carefully, paced around the magic book for a while, and after making sure that there were no traps, he slowly stroked the book cover with his hand, and then slowly opened it.

Although the magic book is very thick, each page is made of white bone, and the pages are relatively thick, so the number of pages is really not very large.

Each page basically records a necromancy.

Some of these necromancy spells are represented by words, and some have magic circles. The characters are varied, including elven jade, dragon language, lingua franca, etc., and the magic circle is also varied, with pentagrams, six-pointed stars, crescent moons, and the shape of the sun......

Cangsu couldn't help but be deeply attracted, and his breathing was much lighter for a while.

Rao is other three people are companions who have lived and died with him, and at this moment, looking at his fascinated appearance, they all have a little chill.

Although Cangsu looks like a living person and can breathe, he doesn't actually need to breathe, he just doesn't want to behave abnormally.

This is the necromancer.

They play with the soul, play with life, and challenge death.

"How's it going?" the knight boy broke the silence.

Cangsu woke up in shock, he took a deep look at the magic book, and then closed it, his tone full of emotion: "Valuable!"

This is a silver-level magic equipment with a lot of spells recorded in it.

As long as enough magic is instilled, it can be cast, eliminating the need for magicians to build spell models with spirits, which is very quick and convenient.

Of course, it needs maintenance.

Too much use of it can cause the pages or even the entire book to fall apart.

During the production of this book, many spell-casting materials were mixed in. Usually, when you use this magic book to cast magic, you will secretly consume the spellcasting materials inside.

"It's just this book, and you can't change ten silver-grade lifting scrolls!" Cangsu made an analogy.

In addition to this magic book, there are many magic items on the messy circular desk.

Of the few, only Cangsu is a magic book and is very knowledgeable, but he can't identify all the items for the time being.

According to rough statistics, the value of the items identified by everyone so far alone has exceeded the value of the lifting scroll by about ten times. And that's not even counting the black-skinned, white-boned, magic books, and all the books placed on the walls.

Ayosu took out a leather scroll inserted into it from the pen holder.

He rolled the leather on the table, unfolded it, looked at it a few times, and said happily, "This should be the chart we are looking for." ”

Waves, islands, and boats are moving slowly on the chart.

This is the activity map.

The knight boy was happy: "It seems that I don't need to buy new event maps, we already have them." ”

Cyanobacteria shook his head: "My lord, this map is too small, and the scope depicted is not as good as a normal sea chart." ”

Cang Xu laughed: "So what?"

As soon as he finished speaking, he mobilized his spirit and magic to manipulate the moving chart.

The contents of the chart immediately shrank, and the entire sea area shown on the chart suddenly became huge.

Cyanobacteria exclaimed, "There are all Eidolon Sea Areas, and the value of this chart is very high!"

The Eidolon Sea is where everyone is right now.

Cangsu flicked the map and quickly zoomed in again: "These places have been specially marked, and they should be the places we are going to explore next." In these places, it is likely that the main shrine of the Meizu Blue God is hidden. ”

The group searched this level and then descended the spiral staircase to the next level.

The lower floor is clearly a storage room.

Inside, there are three rows of shelves on which various supplies are placed. Most of them are spellcasting materials, including skeletons of various races, seaweed shaped like human hair, and still moving eyeballs.

The preservation of these spell-casting materials has obviously taken a lot of thought.

For example, those moving eyeballs are soaked in glass jars, immersed in a thick green liquid.

"Look, these are probably treasures salvaged from the bottom of the sea. Cyanobacteria spoke.

On one shelf, a bunch of treasures were placed at random. A large number of gold, silver, copper, as well as gold and silver jewelry, crystal cups and so on.

Cangsu guessed: "This necromancer has ghosts to drive, they can explore the bottom of the sea, and it is not difficult to find some treasures of shipwrecks. ”

"However, in this way, these treasures have not been kept in the hearts of the owner of this secret room. There must be more valuable treasure Chinese s!"

The search continued, and finally they found a crouching metal toad in the corner.

"This is a toad safe!" Cang Xu was stunned for a moment, and then said.

It is an alchemical artifact, a spatial device, that holds the most valuable items. It was often used by aristocrats and large merchants.

"Turns it on, it seems like you need a password, right?"

Cang Xu shook his head: "Not only the password, but also a series of identification steps such as bloodline, voice, appearance, fighting spirit or magic power. Only after all the steps have been passed can the Toad Safe be opened. ”

This is a treasure chest with a high specification. It is not a dead thing, there is a material in the process of making it that is the soul of intelligent life!

Cyanobacteria regretted: "The most valuable treasures must be stored here, but unfortunately, our unban scroll has run out." ”

"Unbanning scrolls won't solve this problem. Mango shook his head, "It seems that we can only find a way later." ”

"Haha, that's not the case. Acansu shook his head and smiled, "Don't forget we have this." ”

He pulled out a pearl from his bosom.

This is certainly not an ordinary pearl, this is a strange item produced by the fairy tale of the artifact mermaid.

Each member who escaped from Mystery Island has at least one pearl foam on their body, which can be replenished at any time in case of accidents.

Greybeard just tried to crush it, but stopped doing so. He turned his head to look at the knight boy, "My captain, you should come." ”

The knight boy shrugged his shoulders, he didn't care, but if Cangsu took the initiative to avoid suspicion, it would be even more inappropriate for him to refuse this kindness.

Immediately, he walked up to the toad safe, crushed the pearl foam on his body, and used it on himself.

Then, he instilled his fighting spirit into the half-human-tall metal toad.

The metal toad came alive, and it opened its swollen eyes, and two rays of light shot out of it.

The light shone on the knight boy's body, scanning it back and forth twice.

Then the metal toad sticks out its tongue and has a spike on its tongue.

The knight boy lightly touched his finger to the spike, creating a wound and dripping blood.

The toad stuck out its tongue and closed its mouth, as well as its eyes.

It croaked twice, then opened its eyes again. But this time, its eyeballs didn't glow again.

"Password. It spoke.

What the password is, the knight boy doesn't know anything.

He shrugged his shoulders and said casually, "You're just a toad." ”

Under the camouflage of pearl foam, the metal toad heard the correct password: "You are welcome to use it again, master." ”

It let go of all restrictions, and in an instant, the knight boy with a spiritual link suddenly knew everything contained inside.

There are not many treasures inside.

There is a white bone staff, about a meter four in length, and silver-level equipment.

There is also a magic robe, although it is patched, it is gray and now white, but it is still a silver-level magic robe.

Rich.

But it's no longer a gold coin, it's an amethyst coin.

This small handful of purple gold coins is enough to buy three sea boats booked by the teenager!

The largest number is not amethyst coins, but a black crystal.

These crystals come in long and short shapes, large and small, and are all in the shape of long strips. It is deep and secluded, exuding an inexplicable chill, and the breath is not consistent. Ranging from bronze, black iron to silver.

"What is this?" the knight boy wondered, and as soon as he thought about it, the toad statue spat out a black crystal.

"Soul Crystal!!" Cang Xu was suddenly shocked physically and mentally, and blurted out.

The other three suddenly lost color.

They had all heard of the cruelty of the soul crystals.

"There are at least a thousand soul crystals here. The knight boy's face turned pale.

This means that the master of the underground vault is definitely an executioner who has committed great murder. Because soul crystals are made from souls.

Cang Xu frowned: "So many soul crystals?"

He felt strange.

"Let's see, are there any scrolls or books in there?" the old scholar's tone trembled slightly, his eyes were urgent, and he immediately asked.

There are indeed two books.

The knights and boys all took it out.

The first is a diary, which contains a lot of research, and a few are personal life experiences.

The second book is an alchemy notebook, which records in detail the method and experience of making soul crystals.

"We really sent it!!" Cang Xu clutched the alchemy note tightly with both hands, Rao is usually very calm, but at this moment he couldn't help but be excited.
