Under Edu's gaze, the Warcraft Leather in Bell's hand moved automatically. After twitching a few times in mid-air, it suddenly spurted out a large group of black shadows.

The black shadow was as sticky as a large puddle of oil. It spurted out from the Warcraft leather and fell to the floor, quickly shrinking into a ball.

[Shadow Thorn] Activates suddenly without being stimulated by the outside world.

"簌——"

There was a sound like the wind blowing, and the huddled black shadow suddenly stretched and transformed into a shadow thorn more than four meters long. In an instant, a hole as big as a bowl was pierced through the ceiling of Edu's house.<

/p>

Edu was stunned when he entered the room. He didn't understand what happened at all. But after entering the room, a black light flashed in front of him, and there was a hole in his roof.

The speed at which Shadow Sting is launched is so fast, like an arrow being shot.

In the face of this kind of attack, even if the consciousness can sense the attack, the physical body of a normal adventurer will find it difficult to react.

"Mr. Bell, what is this?!"

Looking at the light leaking ceiling, Edu swallowed.

Edu was stunned by the attack in the room. If the black light had been shot at him when he entered the door just now, his life would probably have been lost.

"Um, the design of this thing is a little different from what I imagined..."

Shaking the leather in his hand that had softened and lost all its extraordinary properties due to the loss of magic power, Bell was also a little scared at this time.

There is no problem with the magic formula he burned, and the Warcraft leather as a carrier can also carry this magic spell.

However, Warcraft Leather cannot perfectly seal this magic power. As long as Bell removes his mental power from the magic formula, this magic formula will be triggered immediately.

"It would be great if I could have a magic scroll made by a mage as a reference. Now I need to solve two problems. One is to replace the material that stores the magic formula, and the other is to add new magic symbols to the magic formula as trigger conditions."<

/p>

Write a new magic symbol, disassemble the complete magic formula, add a restriction, or add or remove an equal sign before the final output, and then add the equal sign when it is used.

Starting with the magic formula is the most permanent solution Bell can think of.

But it is a pity that Bell, who has not used his fire-loving wisdom a few times, is still an illiterate rat at this time.

The magic power reserve in his mind is pitifully small, and it is not enough to support him in making changes to the magic formula.

"But I am uneducated, so it is difficult to realize my ideas."

All Bell can do at this stage is to replace the material carrying the magic formula.

Bell immediately thought of the magic scrolls he had seen in the market before. The mages used a refined magic paper.

The Mages Guild has studied magic for so many years, almost tied to the history of human development in this world. They have developed a variety of magic materials and selected the materials that best balance performance and effectiveness.
p>

If the magic paper used by mages can be obtained, Bell's experiment of making magic scrolls should be much simpler.

But it is a pity that Bell did not see the raw materials processed by mages in the market today. Their profession seems to only buy raw materials and sell finished products in the market.

Rarely seen in the market, semi-finished products processed by mages.

(v?v)Think~

"I suddenly thought of a good thing, which can be used as raw material to burn the magic formula."

Edu returned to the kitchen, and Bell also ran into the pile of materials he bought today, rummaging back and forth.

"Fortunately, I decided to buy sugar cane at that time, otherwise I wouldn't have been able to make this attempt."

After dragging a bundle of sugar cane in front of the tool table, Bell rubbed his hands.

After many generations of magical breeding and cultivation, the green sugarcane in this world has turned into an extremely sweet crop with a frighteningly high sugar yield.

There is no doubt that this is a high-quality sugar crop cultivated by the Agricultural Guild. However, due to the climate problem here in Cangxing City, sugarcane is rarely grown here. It is considered a cash crop for fruits.

In Cangxing City, not many people value sugar cane.

But in Bell's workbench, sugar cane is a good thing. It is an important raw material for synthetic paper.

With paper, Bell can synthesize books, maps, cartography tables, fireworks and rockets...

These props have their own uses, and Bell believes that they can maintain a considerable part of their extraordinary characteristics after being converted into the real world.

While thinking, Bell synthesized paper.

Soon, this large bundle of sugar cane turned into two sets of paper.

Bell took out a piece of paper and placed it in front of him. He found that the materialized paper was just a square piece of paper.

But as paper produced by the tool table, these paper pieces are almost 100% compatible with magic.

They perfectly utilize the characteristics of paper. A piece of white paper can be dyed with any color and display it perfectly.

"It is very easy to burn the magic formula on these papers."

Putting the three pieces of paper together, Bell quickly completed a shadow tattoo.

Just like when drawing the shadow thorn before, after the magic symbol was drawn, the magic power in the entire room was quickly drained away.

After the magic formula absorbs enough magic power, it begins to change rapidly, and the next moment it triggers the magic effect of the shadow thorn to launch an attack.

"Now, just hold it back."

Seeing the right opportunity, Bell grabbed three pieces of paper with magic formulas engraved on them and stuffed them into the tool table, and the surging magic power fluctuations instantly dissipated into nothing.

Bell successfully used the workbench to synthesize three pieces of paper and one piece of leather into a book.

"Once you enter the workbench, no amount of magic can cause trouble."

Taking out the books on the workbench, Bell played with the small square-shaped book in his hand. He could feel that the magic formula in the paper had not dissipated after being synthesized into a book.

The book is like an enchanted book, flashing with light, and the activated magic formula falls into a stagnant state in the next second.

"Open this book, the magic in it will continue to flow, and the shadow thorn will also be activated."

After continuously synthesizing three magic books with shadow thorns engraved on them, Bell kept tearing open the magic books in the room and released the shadow thorns to experiment.

Finally, I summarized how to use [Bell's Magic Book·Shadowthorn], which can be summarized in four words:

This is the enemy!

Open the magic book, and the direction in the book is the direction in which the shadow thorn will be released.

Compared to Warcraft Leather, which has no way of figuring out the attack method at all, the Shadow Thorn with books as a carrier can at least not be confused about the direction of attack.

"The only pity is that the walls of Edu's house seem to have become a bit miserable..."
Chapter completed!
