The knight boy, Zong Ge, Cang Xu and others came to the small dock.
The floor of the small dock was lifted, with Bai Ya and San Dao staying on top while the others went into the water.
The sea water during the day sweeps away the eerieness of the night. Although it is blocked by the dock, the sunlight shines on the long coastline and penetrates to the seabed.
When he first entered the water, the young knight felt a chill. But soon he got used to it and felt that the water was bright and warm.
Due to the refraction of light, the starfish, shells, aquatic plants, rocks, valleys, etc. on the seabed are dyed with a layer of colorful colors, which is very beautiful.
As a young man, Zong Ge can swim, but the best water quality is cyanobacteria. He was originally a fisherman, and now he is swimming in the sea as agile as a fish.
But no matter how good the water quality is, it can't be as good as Cangxu.
Because Cang Xu's body has been transformed, this is the secret method of the undead.
Others exhaled breath bubbles from time to time in the sea. After a long time, they had to surface for air. But Cang Xu didn't, he didn't even need to breathe.
The living environment on the Mysterious Island was extremely difficult, and many people died. The main factor that allowed the elderly Cang Xu to survive was his transformed body.
The sea water was not deep, and soon everyone fell to the bottom of the sea.
Above their heads is the dilapidated small dock. Because of the shelter of the dock, this seabed is obviously darker than the surrounding ones.
Cang Xu pointed his finger not far ahead, indicating that this was the valve entrance to the underground chamber.
But the knight boy, Zong Ge and others could not see any clues, they only saw a piece of sea sand.
The crowd was well distributed around the valve.
Cang Xu took out the scroll of liberation from his arms.
The young knight spent all his capital to exchange for three such scrolls. These scrolls were valuable and almost depleted the young man's savings.
After Cang Xu provided the information, the young man thought carefully and decided to take a gamble.
Why not gamble?
They are not on the Mysterious Island now. They are protected by Pearl Foam and so on. Their situation is not critical now. Even if they lose the bet, their lives are not in danger.
As for the loss of capital, just make more money!
However, when Cang Xu unfolded the scroll of unblocking and began to instill magic power, the young knight's heartbeat accelerated slightly with a calm mind.
Zong Ge and Lan Zhao also looked nervous.
The magic circle engraved on the unblocked scroll lit up with gray-white light, and then the light expanded rapidly and flew out of the scroll.
The scroll was originally densely covered with writing, with a circle and a five-pointed star engraved in the middle, but now it became completely blank.
Cang Xu manipulated the gray-white light group and slowly and carefully brought it close to the valve.
Soon, the usually ordinary sea sand was filled with a purple-black halo.
The closer the gray-white light group gets, the more obvious the purple-black halo becomes, eventually forming a changing light and shadow that covers the valve entrance.
Gray white and purple black finally come into contact.
The purple-black light and shadow are like snow encountering sunlight, melting rapidly at a speed visible to the naked eye.
Of course, the gray-white light group is also being consumed.
After more than a dozen breaths, the gray-white light group was all consumed, and the purple-black light and shadow was also reduced by half. A black smoke rose from the light and shadow, which was rapidly replenishing the purple-black light and shadow.
"No, this defensive array can also replenish itself." Everyone's hearts sank when they saw this scene.
Blue Algae did not continue to look at it. He was the first to surface and began to breathe.
Although his water quality is very powerful, the boy and Zong Ge are stronger and their strong physical qualities allow them to hold their breath for a longer period of time.
When the blue algae fell to the bottom of the sea again, Cang Xu had already unfolded the second unlocking scroll.
The gray-white light group appeared again and fell again without giving the defensive array more time to replenish it.
The posture he fell into this time was obviously much firmer and more violent than before.
The unblocked scroll was indeed of silver level, its power was worthy of its high price, and the purple-black light and shadow completely dissipated.
However, another layer of dark golden halo emerged.
Obviously, this is another defensive array.
The gray-white light group shrank a lot, and after trying to eliminate the dark golden halo to the extreme, it completely disappeared.
Cang Xu once again unfolded the third unlocking scroll.
The blue-green algae found it hard to breathe again.
This wasn't because it was time to hold my breath, but because I was nervous.
He knew that the knight boy had almost exhausted his capital and exchanged three unlocking scrolls. In such a short time, he had already used the last one. And no one knew how many layers of defensive circles there were in this underwater chamber.
The third unlocking scroll has been used.
The gray-white light group disappeared completely, but the golden halo still persisted until the last moment. Although the halo was very thin, it still remained stubbornly.
"Failed!" The knight boy, Lan Zao, and Zong Ge all felt their hearts sinking slightly.
Cang Xu remained calm.
He looked thoughtful.
When he unfolded the third scroll just now, he almost believed that this layer of defensive formation would be wiped out. But he didn't expect that it would persist until the end.
"This is not common sense."
"The Unlocking Scroll can dissolve most magic circles, unless..."
It was like a flash of lightning flashed across Cang Xu's mind.
"Unless this person adds other means to the magic circle, there will be no way to restrain the unblocked scroll!"
So, what is the method?
The first thing Cang Xu thought of was necromancy.
Necromantic magic has not been created for a long time, so it seems mysterious and unpredictable, and difficult to target.
Cang Xu then activated the necromancy spell to test the defensive array.
He failed.
But soon, he started to try again.
Cang Xu is a black iron-level necromancer, but he is not good at magic circles. Therefore, his attempts are just attempts, and there is no certainty in his mind.
Just when he himself began to despair, he released the ghost, penetrated the magic circle easily, and entered directly into the underground secret room!
"Sure enough, my previous guess was correct!"
Cangxu became energetic and quickly commanded the ghost to destroy the magic circle.
Soon, the ghost successfully destroyed the magic circle inside.
"Success!"
"Cangxu, well done!"
These words of appreciation can only be temporarily held in the hearts of others.
Cang Xu motioned to Zong Ge to open the valve.
Without the obstruction of the magic circle, Zong Ge floated to the surface to take a breath and then swam down again.
He brushed away the sea sand, revealing a round valve made of bronze.
The valve does not have a handle.
Just when Zongge was in extreme trouble, Cangxu took out the shovel.
Everyone was not surprised, they all knew that this old scholar had a space bag sewn on his body.
Zong Ge inserted a shovel into the gap in the valve, and used his hands and feet to slowly pry the valve open.
There is still a magic circle running inside the valve, which isolates the sea water and prevents backflow.
After Cang Xu expressed safety, Zong Ge took the lead in entering the underground secret room, and then the others filed in.
The light in the underground secret room is bright, and the walls are glowing.
The surface of the wall is coated with a kind of paint that emits a shimmer. The shimmer gathers to keep the secret room bright all year round.
This kind of light is very soft and not dazzling.
The walls of the secret room also seem to be made of bronze. There are no right angles between the walls, but round shapes. This design is probably to gain as much internal space as possible.
As soon as everyone started to enter, the surrounding walls surrounded their bodies, like a well. There were colorful light spots on the walls, sometimes emerging and sometimes disappearing.
If it were an enemy, these light points would emit magical light and strangle the enemy. However, because the ghost was destroyed internally, this last defensive method did not take effect.
After floating down for a certain distance, everyone came to a relatively huge room.
The room also has round walls, and there is a circular table in the center, which is made up of four tables. There are various instruments on the table, including a huge magic book about half a person tall, and an alchemy tool.
Set of flasks, crucibles, etc., as well as crystal balls and white skulls.
Against the wall are bookshelves. The bookshelves are spliced together to separate the wall, forming an inner bookshelf wall.
The bookshelf is filled with densely packed books.
Zong Ge glanced around and saw some book titles: History of Magic, Magic Theory, Common Transformation Potion Making (Part 1, 2, 2), Dictionary of Hell, Encyclopedia of Dragon Language Magic, Diary of the Dead, Nine-Year Magic Examination Mock Exam Questions,
Analysis of Shengming's teachings, the legend of Charming Blue God...
