After deciding to make the magic weapon herself, she took her usual reserves: spirit stones and spirit jade, which are the most basic materials for building magic weapons.

Most of the ordinary weapons are steel or iron, but as magic weapons, they do not assume more of a role like ordinary divine weapons, to cut through thorns and thorns, to split bricks and stones, and their primary role is to store mana, conduct mana and release mana instantly.

The judgment of these three points is the standard of the primary function value of a magic weapon.

Secondly, it is the extensibility, compatibility, durability and resistance of the magic weapon.

Spirit crystal, spirit jade, and spirit stone, these are the three core materials to create a magic weapon.

Among them, the spirit crystal determines where the limit of a magic weapon's mana storage is, it is the upper limit of a magic weapon, how high the level and quality of a magic weapon can finally reach, in addition to the craftsmanship level of the caster, the spirit crystal is very important.

Lingyu determines the conduction of a magic weapon, instantly releasing mana, that is, the size of the explosive power, Lingyu is not the largest component of a magic weapon, it ranks second, but it is equally important.

Although the spirit crystal can store a large amount of mana true element, it is useless to just release it, it needs to conduct mana out, and then accurately deliver it to where it needs to go.

In this process, the transmission of mana is crucial, because the slightest mistake can lead to damage, delay, or even delay.

In the fighting methods of great cultivators, every minute counts, and no one wants the magic weapon they use to be released in the next second.

At the same time, the spirit jade also bears the expansive role of the magic weapon, for example, how large and fine the magic circle can be withstood by a magic weapon, which depends on the material of the spirit jade.

The harder the material, the higher the purity, the more it can carry a high-strength and high-precision magic circle, because the high-strength and high-precision magic circle means that the magic circle has a greater magnification of the spell strength, or the stronger the magic weapon is born with, when released in an instant, if the material is not hard enough and the purity is not high enough, it will easily cause the magic circle to collapse, and even further backfire on the user.

The spirit stone determines the durability of a magic weapon and the ability to resist hits, although these abilities are ranked later, it does not mean that they are not important, but compared with the previous ones, they are slightly less important.

If the spirit crystal is the upper limit of a magic weapon, then the spirit stone is the lower limit of a magic weapon.

How bad a magic weapon can be depends on the spirit stone that created it, and whether a magic weapon can still be strong and undamaged after a hundred battles also depends on the spirit stone that created it.

Among the many kinds of magic weapons, some magic weapons do not need to clash head-on, so the spirit stone to create it does not need to be of high quality and grade, but some magic weapons need to charge into battle and take the lead in fighting, then the spirit stones they need must withstand the fierce fighting, blows and grinding, otherwise they will hit half of the middle, and the magic weapon will break, isn't it funny?

Senior Sister knows the characteristics of Li Chengfeng's fighting technique: he is proficient in hand-to-hand combat, although he has a certain long-range ability, but compared to the senior brothers and sisters who have been practicing for a long time, Li Chengfeng's long-range fighting ability is very weak. Behind the close, that's when he's most lethal.

Therefore, this magic weapon must not only have a strong long-range attack power, but also be able to give full play to his melee advantage, so she knew that she could not create an indirect combat type magic weapon for Li Chengfeng.

For example, Zhou Yuyi's "Purple Gold Soul Jade Plaque" that Li Chengfeng once encountered was a typical "indirect combat-type" magic weapon, they did not directly fight with cultivators, let alone use themselves as a shield to defend cultivators against opponents' attacks, so they did not need much strength to resist attacks.

Because of this, the biggest weakness of this type of magic weapon is the fear of direct confrontation.

Once a practitioner grabs the opponent's magic weapon and attacks it violently, launching a frantic attack in a short period of time with precise and powerful strikes, causing the magic weapon to burst, then they are finished.

But in the ordinary fighting method, very few monks really do this.

Because for the user of the magic weapon, if the other party can burst out with such a powerful force, and even break his most powerful magic weapon, then if he doesn't run, will he stay and wait for death?

For the attacker, why does it come to attack a magic weapon without killing the user?

In addition to indirect combat weapons, there are also auxiliary healing weapons, auxiliary buff weapons, auxiliary curse weapons, auxiliary summoning magic weapons, and direct combat magic weapons.

The five most famous divine swords in the world are all direct combat magic weapons!

Each of them can break new ground, they can all stand alone, and they can all charge into battle!

The direct combat magic weapon that Senior Sister wants to create for Li Chengfeng at this time!

She wants to make Li Chengfeng the most powerful and indestructible weapon in his hands, so she must give him an indestructible magic weapon!

The elder sister walked to the bottom of the furnace, and the tumbling lava made her face glow red, but as if she did not feel the suffocating heat, she raised her hand, and the molten pool rumbled, and the lava tumbled, and a staircase slowly rose from it.

The elder sister walked forward, and a thick layer of frost formed under her feet, wrapping the surrounding flames and the hot and red staircase, but they were instantly melted into water and dripping down, but in the process of dripping, they quickly solidified into ice again, which caused the entire staircase to look like countless ice picks hanging upside down, which was a spectacle and a sight to behold.

The senior sister walked to the furnace, she beckoned, and a Qiankun bag flew out of her hand, and this Qiankun bag was poured into the furnace of the furnace, and hundreds of catties of spirit stones were poured down.

It didn't take long for these spirit stones to soften when they came into contact with the boiling lava, and the outer stones were burned into soft lava, revealing the most essential mineral parts inside and slowly sinking, while the dark impurities floated on the upper layers, making the entire furnace look black and red.

After about a quarter of an hour of burning, a hole was opened under the furnace, and bright red spirit stone juice flowed out along the outlet, which was the purer part of the material, and they flowed down the trench, gathered at the storage tank of the block, and began to quickly solidify into gray bricks under the influence of the surrounding icy cold.

Then there was a clatter of gears from beneath the furnace, removing the brick, and the furnace tilted rapidly, pouring the black impurities that had been melted out and floated on the upper layer into the pool.

Then the senior sister repeated this step, poured the spirit stone again, and cast one spirit stone brick after another, when they accumulated to hundreds, she raised her hand, and put all the cast spirit stone bricks into the furnace, refining again, this time, the senior sister held a flame in her palm, threw this flame into the furnace, and immediately the furnace boiled violently, smelting the hundred spirit stone bricks into juice.

After the bright red dissolved juice flowed out below again and solidified, the spirit stone bricks at this time had already revealed gray and white, and it looked much purer than before.

The senior sister repeated the steps repeatedly, taking one catty of dissolved juice for every hundred catties of spirit stones and solidifying into a spirit stone brick, while every hundred spirit stone bricks continued to be refined, and once again only took one catty of essence.

When the gray-white spirit stone bricks made by this second tempering accumulated to one hundred, they were put into the furnace again for the third quenching, and still only one catty of dissolved juice essence was taken.

The spirit stone bricks condensed by the third dissolved essence were pure white, and they looked a little transparent.

The senior sister glanced at it and continued to repeat the operation.

These days, in addition to returning to the forbidden land to practice for Li Chengfeng and the others, the senior sister stayed in front of this furnace, not moving an inch, and when she finally gathered a hundred pure white spirit stone bricks, she once again put them back into recasting and refining.

And this time is the last time, the quenched spirit stone bricks are pure white and transparent, and you can almost see the opposite side at a glance, like crystal.

This time, the senior sister saw the quenched spirit stone brick, and then she showed satisfaction, and for this spirit stone brick with a purity of almost 100% and so hard that it was incredibly hard, the spirit stone mine consumed by the senior sister was: one million catties!

And to cast the magic weapon she wants to build, she needs a full twenty of these top-grade spirit stone bricks of the highest purity, that is to say: she needs 20 million catties of high-grade spirit stones, a full 10,000 tons!!

And a pound of high-grade spirit stones is equivalent to ten taels of silver, and the cost of casting a high-grade magic weapon, the cost of light spirit stones, is 20 million taels!

This is equivalent to the tax of Tong'an, the most prosperous city in the Northland, for a whole decade!

A top-notch magic weapon, the financial and material support required behind it, ordinary people can never imagine!

What does it mean to be poor and rich in martial arts, and to destroy your family and practice?

And this is!

What does it mean for a poor ghost to play a talisman and a rich man to play a treasure?

This is it!!
