When he found Neheon again, he was staring at the defenses of the entire territory, shaking his head and sighing, leading Leo to a small reception room next door.

"Leo, have you found an alternative material?" As an alchemist, Niheon had no hope in his heart when he heard Leo's request, he could guess some of the mysteries, but because he guessed, he knew very well that this was a very limited method of defense.

Leo didn't answer, but asked rhetorically, "My lord, are the defense towers in the entire territory made of the same material?"

Neheon frowned, a little annoyed in his heart, this kind of question was similar to asking about the secrets of the entire tower, but out of the expectation of the first super territory of the human race, he still replied: "Yes, the materials used to build the tower are the same, but the different witch circles that are refined cause the materials to be different. ”

"My lord, can you provide me with some of this material? Leo added.

"Gray rhenium?" The core of the defense tower is the witch array and the specially refined gems on it, and a little material is not enough to embarrass Neheon, "No problem, I can give it to you now." ”

Leo took a gray stone, this stone has not been polished and belongs to the rough stone, "My lord, go and study this gray rhenium stone first, and then report to the adult." ”

Nehean nodded noncommittally, and after watching Leo go out, he took out a book and looked through it, trying to find out if there was any knowledge that could be used for defense.

Leo returned to the room where he lived temporarily, and after decorating it, he plunged into the God's space, and stretched out his hand and pointed at the insect and the woman who ushered in him, and the two instantly turned into two small dots.

The gray rhenium stone was placed on the desk, and Leo walked over to the rows of bookshelves, he remembered that there was a material mentioning this kind of stone, although he had studied it at the beginning, but it had not been used for a long time, so it was a little blurry, and he had to dig it up again.

The collection of books in the space at this time is extremely rich, which is the result of Leo's hard work for so many years, but he is not a computer after all, and his knowledge has not been used for a long time, and it is inevitable that he has some unclear memory, and the consequence of not being able to extract knowledge directly is that he has to look through them one by one.

After all, he had a certain impression that Leo was very quick to rummage, and a book called 'Compilation of Curious Things' was brought to his desk and carefully studied.

Gray rhenite, the ratio is higher than that of iron ore, and can be used in iron furnaces, blast furnaces and other places with extremely high ignition points, precious materials.

"Is the ignition point high? I don't know if it can be a carrier of electric runes. Leo muttered to himself and began to prepare.

As the first basic unit rune discovered by Leo, the electric rune has been used by him until now, and it is incredible to think about it, and sometimes he is really very glad that this rune was discovered.

Leo's movements are very fast and steady, he doesn't know how many times he has refined the electric storage runes, and the key and difficult points are as easy for him as drinking water.

This time, he did not use alchemy, but directly used the enchantment, and the light of the electric rune flashed away, and it was vividly imprinted on the gray rhenium.

A little bit of light lit up on the gray rhenium, and as time passed, the electric storage rune on the gray rhenium became brighter and brighter, which was the electric storage rune that was storing electricity on its own.

Leo breathed a sigh of relief, the gray rhenium stone could enchant the storage runes, and he would save a lot of things, and he would be able to add another layer of protection to the existing defense system.

'Crackle'

The electric storage rune exploded in an instant, and Leo's originally sunny face was covered with dark clouds, just now it was the electric storage rune that accumulated more than his own power volume to produce an explosion, and he encountered this situation not once or twice.

There are many cases of enchantment failure and explosion, most likely caused by the conflict between the material itself and the rune, followed by the ability of the rune and the material to produce some kind of reaction, which exceeds a certain boundary and explodes, and finally is caused by the enchanter's mistake in technique.

Leo directly ruled out the last one for three reasons, he had this confidence, and then he began to analyze the gray rhenium stone and the specific ingredients, whether there were conflicting elements in it, or whether there were elements that could mutate the storage runes.

The rune exploded while the gray rhenium was intact, this situation was most likely caused by the second reason, but the first was not impossible, so Leo had to start analyzing and detecting it.

The most common method of analysis and detection of wizards is to use potions of different properties, which can react with ingredients of different properties, and determine the composition of their ingredients.

The detection agent belongs to a kind of standing medicine of wizards, Leo does not need to make it on the spot, and directly generates a row of detection drugs in the space, and picks them up one by one and drops them on the gray rhenium, and keeps recording various data with his right hand.

"Trouble. ”

After the inspection, Leo's brows were tightly locked, and the materials he chose for the previous enchantment and storage runes were all materials that could store electricity, just like the purple heart wood he got at the earliest, and the skin of the whale octopus.

Since the material itself can store electricity, it will stop storing electricity when the storage rune absorbs the electricity to saturate, and the material itself can also keep the power from being lost.

However, the gray rhenium stone can enchant the storage rune, and it can also store electricity, but there are more resistive substances in the composition, which causes the rune to store too much electricity and fails to introduce it into the carrier in time, so that the rune itself can produce a load before the explosion.

If you fail and you find a conclusion, you have to find a way to solve it.

Leo had a solution, but this solution made him frown, and his brow furrowed even deeper when he thought of the vast field, the dense towers.

"Phew, it doesn't matter what he does so much, there are so many existing conditions, and it doesn't matter to me whether he can succeed or not, if it's not for the space stone, how can he find guilt here. Leo muttered, immersed in the experiment.

A day later, Neheon received news that the president of the Alchemy Guild had returned from looking for something, and he walked out in his black robe.

"Neheon, have you found that Leo Gamor, can his defenses be used?"

"Elder, the defense system is indeed useful and very effective, but it cannot be implemented due to the limitations of materials. ”

"How could he be limited by materials, could it be that he used rare level materials?" Although the chairman looked old, his voice was indeed full of energy.

After Niheon's 1510 report, the two fell silent for a while, and at this moment, a voice came from a distance, "Lord Nehean, I have a way to solve the material problem." ”
