Wizard: I brought the wrong system

When Yarrow came to smelt the iron again, he suddenly realized that he had done a stupid thing.

The melting point of iron is higher than that of silver, and the molten iron will melt the originally outlined silver core with it!

First make the steel sword body, and then pour the silver liquid?

How to do the hollow part in the middle of the steel sword body?

What the magic hand builds is a palm structure, and it is impossible to do the hollowing out inside!

Yarrow couldn't think of a good solution, so he could only give up the one-piece structure, make it into a folded shape, and then carve the hollow shape into it.

However, for a long sword made in this way, the hardness of the opening will definitely be affected.

Yarrow's solution is to make the opening in the shape of alternating teeth. When closed, the tooth structure at the opening will fit into each other like a zipper, so chopping will not have a direct impact on the gap.

After carving these details, the third important structure of the Blazing Sword is completed.

Heat dissipation and steam release structure on the hilt.

The steel body on the surface of the hilt depicts a series of concave cylindrical hollows. These hollow structures will walk in the vacant positions of the nail caps to absorb excess heat from the palm.

The key is that the sword grid in the middle needs a small mechanism to release the stored steam, and the carving of these positions needs to be extra fine.

Yarrow carved it carefully for a long time, and even if he accidentally made a mistake, he could gradually soften it with hot melting and re-modify it.

Yarrow, who had enough opportunities for trial and error, finally carved it out successfully.

In this way, the overall structure is completed.

Yarrow put the silver core into the unfolded steel sword body, and then activated the 'hot melting technique' to close the steel sword body.

Then take out some stones, put them in the mosaic position originally reserved for the 'hot molten stone', block all the silver cores in the middle, then heat the whole body, and beat it with a hammer to fill in the gaps that may exist in the middle Reality.

Finally heating and quenching.

"laugh--!"

Sparks rose with a puff of blue smoke, and the stench of oil filled the entire laboratory.

The bright red sword gradually faded to black and blue. Yarrow opened the door of the laboratory, and waited until the unpleasant smell had dissipated, then took out the pitted and inconspicuous long sword from the quenching liquid.

The first thing is to remove the miscellaneous stones, and then insert the cut hot melt stone, and then take it to the whetstone for continuous grinding, to grind the surface neatly, and to sharpen the blade.

Following these procedures, the blade of the sword gradually glowed and became brighter and brighter.

Up to now, this fiery long sword is actually almost forged, but the hollow pipe left by the hilt needs to be filled with some water-locking things.

The first thing Yarrow thought of was the "super absorbent resin" in his previous life. This is actually an artificial material. It is used in many artificial snow in film and television works. It is still used in toys such as diapers, ashtrays, and decompression toys. And so on are used.

The molecular structure of 'superabsorbent resin' has network molecular chains. When the water-absorbing agent encounters water, it will be electrolyzed immediately and dissociated into positively and negatively charged ions. These positively charged and negatively charged ions have a strong interaction with water. Affinity, so it has strong water absorption and water retention, can quickly absorb water hundreds of times or even thousands of times heavier than itself, and swell into a hydrogel after absorbing water.

Filling the hilt with this material, and using paper as a spacer material, can ensure that when the steam release structure is opened, liquid water will not follow.

But... After all, this is a man-made material, and Yarrow can't make it!

In fact, it has good water storage like flour, but Yarrow's sword hilt will heat up later. If flour is used, cooked food can be eaten soon, and the so-called water storage will naturally disappear.

So what Yarrow chose was a kind of shell powder in this world.

The properties of this shell powder are somewhat similar to 'superabsorbent resin', and it is a common material used to remove moisture, and it is also highly absorbent.

Carefully pour these shell powders into it, and then use the 'Water Fetching Technique' to add pure water to it, and the long sword of fire will be considered successful.

……

After taking a short rest and eating something casually, Yarrow began to study the 'airship power core' given by Bosco.

Then... I don't understand!

All kinds of magic patterns are densely painted on it, which is not something that beginners like Yarrow can understand!

However, these magic lines also have some divisions. Yarrow tried to input the magic power, and after several attempts, he finally found the correct location for the magic power input.

In fact, this is also easy to understand. Any appliance that wants to accept external forces will naturally have a port to connect to the outside world, just like the circuit on a toy. This is what Yarrow is looking for.

After confirming the input end, he carefully input a little magic power, the 'airship power core' buzzed, and a gap at the outer end of the metal ball gradually rotated half a circle.

It seems that there is too little magic power and the driving effect is too poor.

But Yarrow's goal has been achieved, and he has determined another component, the position of this rotation is the power output end.

……

In this way, Yarrow experimented bit by bit, gradually cracking the structure on the metal sphere.

The metal ball was not sealed, and all kinds of magic patterns emerged on the surface. After confirming more and more structures, Yarrow gradually found the few structures he wanted.

First, the magic absorption structure.

This is the refueling port of the 'airship power core', which can also be understood as the battery part of this thing.

Second, the kinetic energy conversion structure.

This magic pattern, after inputting magic power, will generate rotating wind power.

Third, the kinetic energy control system.

This is better understood, it is the system of adjustment and control.

After confirming the structure of these three magic patterns, Yarrow finally walked out of the room, went to Life Corner Street, and bought some magic pattern ink.

Then he went back to his laboratory without stopping, and imitated the magic pattern structure of the 'airship power core'.

The mechanical structure of the "airship power core" is very simple, as long as the magic pattern structure can be successfully reproduced, the experiment of "measurement of the speed of light" can start immediately.

And then...failed again.

The magic pattern is not as simple as Yarrow thought Xiangzhong, it is not a simple replica of the external appearance, and the replica can be successful.

Yarrow had to go to the library again to rent books on magic patterns.

As time passed, Yarrow also gradually understood the key to the knowledge of the magic pattern.

The original magic pattern was actually a replica of the structure of different spells, but after a long period of development, it gradually grew into a brand-new discipline, which took a different development path from the structure of spells.

Magic pattern is also a kind of subject!

But if you want to learn magic patterns well, you must first return to the issue of spellcasting.

Just like the problems Yarrow encountered when learning tricks for the first time, the magic pattern also needs to pay attention to the thickness of the ink, the angle of conversion, whether it is a one-stroke or multiple links, the type of magic pattern ink...etc.
