Sitting on the single sofa in the bedroom, Lin Yi stared at the air in front of him seemingly without focus, holding a golden pen in his hand, constantly writing and drawing on the blank paper.

Finally, after writing two sheets of A4 paper, Lin Yi put down the pen in his hand heavily, and a heartfelt smile appeared on the face of the fair-skinned handsome, who had not seen the sun for three days.

These days, he's mostly studied and these two spells for repair and cleanup, as well as this slightly more low-level Transfiguration Charm.

The purpose is also very simple, that is, to make a magic weapon that can repair weapons.

This is something that Lin Yi has been thinking about all along, after all, this feeling of having a powerful buff skill but not being able to use it all the time is really uncomfortable.

So after Lin Yi saw the ability, he immediately thought of this.

In his vision, this magic weapon will use its power to clean all the dirt from the weapon, and repair the durability of the weapon with the repair and deformation power of harmony.

After many spells and rules have been repaired, even a battle-scarred sword will be re-brand-new when put inside.

It is worth mentioning that Lin Yi's thoughts and ideas are correct, but the truth is far from being as simple as he thought, because this spell equivalent to the nature of the foundation in this idea has considerable limitations.

It can't repair the damage caused by some rare, powerful curses, or perfectly repair objects with powerful or complex magic like vanishing cabinets and wands.

It can only repair the damaged items to their original state from the physical level, and it is difficult to repair the damage caused at the magical level, let alone the durability of the system's properties.

Therefore, Lin Yi was troubled by this problem for a long time, until he inadvertently pulled all the items in the inventory into the deduction category, and then unexpectedly deduced a qualified design drawing.

In this design drawing, Lin Yi used something that Lin Yi had been thinking about in the past - fish beam wood.

That's right, it's the fish beams that are all over the continent of Westeros in A Song of Ice and Fire.

This gray-white deciduous tree unexpectedly has a very high compatibility with the spells of the Harry Potter world, not only can it easily carry many spells, but also has a very strange power.

Lin Yi called this power.

Because it can maintain items in a constant state from both physical and magical levels, and can even achieve a pseudo-immortal effect without external interference.

After understanding this, Lin Yi's mind suddenly flashed the ancestors' description of Yuliangmu.

He should have thought of it a long time ago!

Lin Yi guessed that the immortal power that Yuliangmu possessed on the continent of Westeros should be the embodiment of immortal power on the physical level, and after coming to the world of Harry Potter, its potential at the magical level was also completely released.

Lin Yi picked up the two pieces of A4 paper full of words, the silver-white light in his palm surged, and the paper with the fragrance of ink was cut into pieces by the fine sword qi in an instant.

With a light blow, all the scrap floated into the trash can next to the desk.

Lin Yi is not doubting the feasibility of the system deduction, he is just calculating whether this design drawing can fully have the effect he wants, after all, the fish beam wood materials in his hand are limited, and it is better not to waste it or not.

At this moment, when the calculation was over, Lin Yi no longer hesitated.

He clicked on the sub-class-specific ones, put all the materials required for the design drawing, and then checked the refining technique, and checked the Kanzi Qimen, the Redemption Qimen and the three magic spells on the refining inscription......

And then...... Start refining!

Looking at the progress bar that was advancing little by little, Lin Yi had a smile on his face.

Kan is water, and it is Ze, and the addition of these two Qimen is to strengthen the repair power of the spell, plus the fish beam wood comes with the power of pseudo-immortality, and the magic weapon can.

Fifteen minutes later, the progress bar finally came to an end, and the system also popped up a prompt box, and after clicking OK, the refined magic weapon appeared in Lin Yi's inventory.

It's finally out!

Lin Yi sighed with emotion, quickly cleaned the table in front of him with his hand, and then waved his hand slightly, and a sword box about four feet long and nine inches wide appeared in front of him.

The sword box is made of fish beam wood as a whole, in the shape of an eight-sided diamond, and its surface is carved with delicate and luxurious Ruyi cloud patterns, and the inside is engraved with a combination of complicated and mysterious spells and strange magic.

It may be that it is affected by the power of the spell and Qimen, or it may be that the immortal power in the Yuliang Wood has been stimulated, and at this moment, the Yuliang Wood is no longer as gray as a bone before, but it is as crystal clear as the best high-grade mutton fat jade.

Seeing the appearance of the sword box, Lin Yi gave him a name without thinking about it.

Seeing the slogan attached at the end, the corners of Lin Yi's mouth couldn't help twitching.

This is his idea after reading the description of the prop just now, but he didn't expect that as soon as this idea came out, it was directly pasted on the bottom of the prop attribute panel - in comparison, you are more sloppy no matter how you look at it!

Lin Yi silently complained about the system, and then put his eyes back on the prop description.

"Wood of Destiny...... Immortal Power ......"

Lin Yi's brows furrowed slightly, feeling as if he had discovered something unusual.

Looks like I'll have to remind Tony when I go back, don't take all his fish beam wood seeds.

While thinking so, he took out the Tang knife that had broken during the previous battle with Ma Xianhong from his inventory, and then put the broken Tang knife and half of the blade into the sword case.

Then, he put his hand on the white jade sword box

The sword box that looked like white jade suddenly lit up with a shining light, and silver-white filaments started from Lin Yi's palm and spread along the Ruyi cloud pattern on the surface of the sword box.

Seeing this scene, Lin Yi suddenly inexplicably understood its function - this is a progress bar that looks more bells and whistles, once all the engravings are filled with silver wires, the items inside will be repaired.

Lin Yi patiently waited for the spread of the silver thread.

About ten seconds later, all the cloud patterns were filled with silver threads, and Lin Yi suddenly lifted the lid of the white jade sword box and saw the brand-new Tang knife inside that was intact and shiny.

Taking out the Tang knife, Lin Yi rubbed his fingers on the blade with a thoughtful expression.

When the blade shattered, a lot of fine metal fragments collapsed, that is to say, what he put in before was not a complete Tang knife, but a very small part of the Tang knife fragments were missing.

But even so, this Tang knife was still restored to its previous appearance, and the length and width, and even the weight did not change in the slightest......

Do you really ignore the law of conservation of mass?

Now not only Newton, but even Lomonosov is about to jump out of the coffin board!

Lin Yi complained in his heart, and immediately, he seemed to realize something, and hurriedly clicked on the prop attribute panel.

Sure enough, there is still consumption!

Lin Yi nodded, then he thought about it, and suddenly stretched out his hand and forcibly broke the Tang knife in half directly above the white jade sword box, and then put the two blades and all the metal chips into the sword box.

Closing the sword box, Lin Yi ran the sword qi again, watching the silver threads slowly fill the entire body of the box.

Just like last time, when the sword box was opened again, the broken Tang knife was unsurprisingly restored to its new factory.

…… But what about durability?

Lin Yi opened the prop attribute panel again.

Looking at the value of 998 on the panel, Lin Yi couldn't help but show a satisfied smile on his face.

That's right! That's the right way to open it!
