Level 25 Hellfire, plus the power bonus of level 25 "Warmth", the fire damage caused per second is even twice that of a fifth-order magic meteorite, and its temperature reaches a terrifying 3200 degrees.

Xiao Liu and San'er were stunned as they watched as the material that could not be burned by the fire lava turned into a liquid state at a speed visible to the naked eye.

It's terrifying, what kind of terrifying temperature should this strange flame emitted by Brother Yang be?

But they didn't feel the slightest leakage of temperature, which meant that Brother Yang's control of his own strength had reached a subtle realm.

What surprised them the most was that they still didn't feel the slightest fluctuation of spiritual power, and this red and black flame was completely emitted with another power that was completely different from spiritual power.

This Brother Yang, whose cultivation is unfathomable, is full of mysteries, neither true nor demonic, and he doesn't know where it came from.

But whatever he came from, he was their friend, and they just had to remember that.

The sacrificial immortal sword can't use the dark iron of the entire sword at all, because it has to add some obsidian essence and red copper essence to it, if you use it all, then this sword will be a bit big, and it is completely unnecessary.

It was Yang Yifei who separated a ball of dark iron to see what they needed to refine.

After separating a cloud of dark iron solution, Yang Yifei collected the hellfire, and with a movement of his telekinesis, the materials were evenly fused together.

After the mass of material solution was completely fused and elongated into the shape of a sword, Yang Yifei sealed his hands and cast the method of sacrifice and refining that he had learned from Du Bishu's mind.

As the tricks were played, the fairy sword gradually solidified, and patterns began to appear on the sword body.

More than an hour later, the sacrifice was completed, and a fairy sword with raging flames on the sword body floated in front of several people.

The main body of this fairy sword is black, but the blade of the sword is red, and there is a string of mysterious red runes in the center of the sword body from the tip of the sword to the sword grid.

The shape of the whole sword is like a miniature version of the flaming sword used by the female angel in the Super Divine Academy, of course, what has been reduced is only the width of the sword body, but the length is about the same.

It's a pity that this is just like the Flaming Sword, the power is naturally far behind, the Flaming Sword has the ability to resonate with the solar energy, and the physical power and radiation effects produced are extremely powerful.

The Flaming Sword looks like a sword, but it is actually a stellar weapon with a supercomputing core, which can easily smash huge starships and slash gods with sufficient stellar energy support.

The Torrent World that is stranded on the mysterious side must at least be at the level of a top-grade Acquired Spirit Treasure, the Silver Wing of Divine Kaisha or the Silver Blade of Sumari, and even reach the level of the Acquired Treasure.

The levels of treasures in the Torrent World from high to low are: Innate Treasure, Innate Treasure, Acquired Treasure, Acquired Treasure, Acquired Treasure, Magic Weapon, Spirit Weapon, and Magic Weapon.

There is no grade of the treasure, no matter the congenital and the acquired, as long as it is the treasure, it is not divided into grades, but different treasures have different effects, but it must be a treasure that will exert its own efficacy to the extreme at this level.

Other treasures are different from the upper, middle and lower grades, and there is a gap in efficacy and power.

Yang Yifei's immortal sword, known as the Nine Heavens Divine Soldier in this world, can be put in the Torrent World, and it can't even reach the spiritual treasure, at most it is a medium-grade magic weapon.

In this world, the Zhuxian Sword, the Qiankun Reincarnation Disk, the Xuanhuo Jian, and Zhang Xiaofan's Soul Eater Stick can reach the level of a top-grade magic weapon.

After all, it is only a low-martial immortal world, and its upper limit of force is destined to make it impossible for the treasures of this world to reach the level of the spirit treasures of the desolate world.

However, to be able to have a Nine Heavens Divine Weapon in this world, that threshold is already quite high.

Yang Yifei named this sword "Black Flame", pinched out the trick, and the flames on the Black Flame Sword all converged into the sword body, and with a movement of his mind, the Black Flame Sword crossed an arc in the air, and finally stabbed into Yang Yifei's abdomen, and the entire sword was submerged in his body.

Yang Yifei clearly sensed that this sword had entered his dantian, placed in spiritual power, and was nourished by spiritual power all the time.

This is the difference between refining oneself and using others, the magic weapon of this world can be combined with the master as one, and it is only sacrificed when it is used, which is very convenient.

But there are some strange magic weapons, because their own spirituality is too strong, the human body can't afford it, so it can't do this, and can only be carried by the owner, and the Nine Heavens Divine Weapons basically belong to this kind of magic weapon.

This is also the reason why Lu Xueqi always carries Tianya on her back and never integrates it into her body.

However, there is an exception, if this Nine Heavens Divine Weapon is refined by yourself, and the master's essence is fused with it, then there is no problem.

Seeing that Yang Yifei's refining magic weapon was over, and he had indeed refined a Nine Heavens Divine Weapon, Xiao Liu was very happy for him, "Congratulations to Brother Yang for refining the Nine Heavens Divine Weapon." ”

Yang Yifei tilted his head and said with a smile: "Don't patronize and congratulate me!" There is still a small half of the Nine Heavens Meteorite left, what do you want to refine? I don't know if it's enough. ”

Xiao Liu happily glanced at San'er and said, "More than enough, where our strongest combat power lies, is these sharp claws, so San'er and I plan to refine gloves, and we only need to use some Nine Heavens Meteorite Iron with our fingertip claws." ”

"It's just that we don't know how to refine weapons, so we don't bother the two masters, so let's ask Brother Yang to help us refine it!"

Yang Yifei nodded and said, "No problem, when the time comes, you just need to integrate your spirit into it." ”

Yang Yifei flipped his hand and took out a piece of Damascus steel and used it as the main material, as they said, they only need to use dark iron for the claws of the fingertips, and add a little dark iron to the gloves themselves to improve the strength.

The glove is not a little more complicated than the sword, after all, the glove must maintain its flexibility, and it cannot be monolithic.

Yang Yifei refined the gloves they wanted into a chain glove, extending towards his forearm in addition to the claws on his fingertips and the palm part.

In the palm of his hand and forearm, Yang Yifei added a lot of dark iron, and the fingertip claws were the same material ratio as the Black Flame Sword.

In this way, not only does the fingertip claw have the attack power of the Nine Heavens Divine Weapon, but the section of the forearm can also be used as a defensive part to block the opponent's weapon, and adding dark iron to the palm of the hand can allow them to grab the opponent's weapon.

Refining these two pairs of gloves took more time than refining the Black Flame Sword, and it took three hours, and in the process of Yang Yifei's refining, Xiao Liu and San'er each integrated their own essence and spirit into it, so that they could integrate into their bodies like fingers.

Although the gloves of the two of them can also be regarded as a Nine Heavens Divine Weapon-level magic weapon, they are still half a step weaker than the Black Flame Sword overall.

After all, the entire body of the Black Flame Sword is made of dark iron as the main material, which is integrated and indestructible, but the strength of most parts of the glove is weaker, only the fingertip claws and the Black Flame Sword are of the same strength.
