In a weapon refining room in Langhuan Cave Heaven, Li Muran sat cross-legged, sacrificed his natal magic weapon, the Soul-Chasing Sword, and held it in his hand.

Li Muran gently stroked the sword of the treasure sword. This sword has been with him for hundreds of years, helped him kill many enemies, and was also cultivated by his pure magic power. Among all Li Muran's magic weapons, this sword is most closely connected with his mind and spirit.

In comparison, although the Kanglong stick was once recognized by him, it did not take much effort to cultivate it. Therefore, the Kanglong stick was destroyed and Li Muran was not affected too much.

As Li Muran's cultivation level improves, the quality of the treasures he needs is getting higher and higher. Nowadays, even the ninth-level magic weapon is difficult to get into Li Muran's eyes. This treasure sword only has the quality of the eighth-level magic weapon and can no longer keep up with Li Muran's cultivation level.

"Grieved spirit, come out! The real Japanese people are going to recast their natal magic weapon!" Li Muran said softly.

As soon as he finished speaking, a shadow of ghost face flew out of the blade and floated near Li Muran. This was the spirit of Li Muran's sword.

After the spirit of the weapon left the sword, Li Muran immediately activated the true demon's aura, and a black flame emerged from his palm.

This is the true energy fire that he used his magic skills to activate, that is, the natal true fire of a cultivator. The natal true fire is of great use and is the most commonly used method for cultivators to temper internal alchemy, cultivate magic weapons, and refine external objects. However, Li Muran's skill is special, and he can also activate two natal true fires stimulated by the true spirit aura and the true demon aura.

Li Muran is already a great monk in the late stage of the true body. The true fire he stimulated was very powerful. Under the burning of this demonic energy, the Soul-Chasing and Spirit-Snatching Sword gradually melted, and the impurities with slightly inferior quality in the blade immediately turned into a wisp of blue smoke in the true fire, disappearing without a trace.

After the real fire was refined, the Soul-Chasing and Spirit-Snatching Sword turned into a fist-sized liquid ball, and most of the raw materials in the blade were burned, leaving behind the essence of this knife.

Li Muran's cultivation of this sword for hundreds of years, and his mental connection with this sword is all in this essence. Therefore, although the soul-chasing sword has been destroyed, Li Muran has not been implicated.

However, the vengeful spirit is the weapon spirit of this sword. Now that the sword has been destroyed, it has suffered great suffering, showing a painful look. Fortunately, the essence of this sword still exists, and the vengeful spirit will not be destroyed.

Li Muran immediately took out the star-absorbing iron obtained from the Dragon Palace of the East China Sea, and integrated the essence of the Soul-Chasing and Spirit-Snatching Sword into it, and tempered the two with real fire together.

After seven days and seven nights, after repeated tempering of the true fire, the impurities in it were almost gone. The star-absorbing iron turned into a translucent black liquid bead, which merged with the essence of the soul-chasing sword.

Then, Li Muran stretched out his finger and bounced, and a demonic energy surged out, turning into a flexible magic clutch, pulling and extending the ball of liquid beads. In a moment, a sword was formed, and its shape was somewhat similar to that of the Xuanguang Sword.

As soon as Li Muran collected the true fire, the sword's first embryo immediately began to solidify slowly.

Li Muran then took out the mysterious small mirror and used the mirror light to illuminate the first embryo of the sword. After a stick of incense was shining, the sword was about to completely solidify and form.

At this moment, Li Muran put away the small mirror, took out the talisman sword that had been prepared, and carved the top-level runes on the sword embryo! Some of these runes are solidified runes, which can make the sword stronger; some are hidden runes, which make the sword's hidden magic power stronger; some are dark attribute magic patterns, which allow the sword to exert a little power.

The engraving of some of the runes was originally extremely difficult and almost impossible to achieve overnight. However, because the sword embryo was shining by the light of a mysterious small mirror, Li Muran became relaxed and relaxed when engraving the runes.

More than ten top-level runes were completed in one go! Li Muran put down the talisman pen sharpener, and the sword completely solidified at this time. The runes engraved on the sword embryo were integrated into the sword body and disappeared in the flash of magic light.

"The sword has been completed!" Li Muran said happily: "Although it is still just the first embryo, its quality is far higher than that of ordinary ninth-level magic weapons. I believe that as long as I cultivate it for decades, when the sword opens, it will definitely be a spiritual treasure!"

"This sword is mainly made of Star-Absorbing Meteorite, so it is named Star-Absorbing Sword! Resentful Spirit, you will be the sword spirit of this sword in the future!" Li Muran murmured.

Li Muran put away the small mirror and immediately summoned the demon soul to appreciate the Star-Sucking Sword.

"It's indeed a good sword!" The Demon Soul praised: "As long as this sword opens, you will have two spiritual treasure-level swords, one spirit and one demon. If necessary, the two swords will be combined and the power will be stronger!"

Li Muran nodded, which was also the main reason why he deliberately refined the form of the Star-Sucking Sword very similar to the Xuanguang Sword.

"When refining the sword, why did you deliberately isolate me?" Demon Soul asked with a frown.

Li Muran smiled slightly: "I'm afraid of being distracted. When making talismans and refining weapons, I'm used to completing it quietly alone. If the seniors are present, they will be uncomfortable all over. If they are a little distracted, they may fail."

The demon soul nodded. Many immortal worlds are not used to practicing or others are present when refining treasures, and Li Muran’s request is not special.

Li Muran put the Star-Sucking Sword into his body, cultivated it carefully, and slowly helped him to open up.

Li Muran took out another top-quality purple gold pearl and played with it carefully.

The demon soul said: "This top-quality purple gold bead is actually one of the nine treasure pearls condensed by the clam demon in the late stage of the real body. It is too wasteful to use this treasure to refine the body. It is better to use it as a carrier to refine the natal Yuan Soul Bead! My friend is already a great cultivator in the late stage of the real body, which is enough to refine this method! The natal Yuan Soul Bead can not only enhance magical powers, but also lay a solid foundation for my friend to attack the realm of the Yuanshen Stage in the future. There is even a saying in the immortal cultivation world that if the natal Yuanshen Bead is perfect, he will be half a Yuanshen Stage cultivator!"

...

A few months later, Li Muran isolated the demon soul again on the grounds of making talismans. He took out several top-level blank jade talismans and began to try to engrave the immortal runes in his memory.

He remembered the form of the immortal runes, the order of strokes and techniques of drawing them clearly - after all, he had watched the immortals draw dozens of times with his own eyes!

Unexpectedly, when Li Muran engraved the runes himself, it was impossible to complete the first rune just by the first rune.

When this stroke was only halfway through, there was a strong invisible force that made Li Muran's talisman pen stop or deviate, and he could not complete the first stroke at all.

Li Muran has achieved success in body refining. His arm holding the talisman pen is full of millions of pounds, and he is also blessed with powerful magic power, but he still cannot resist the repulsion of the invisible power, and he cannot draw the first rune smoothly. Even the first rune cannot be completed, and the rune behind is even more impossible to reach.

"It is worthy of being an immortal rune!" Li Muran was shocked, "Every stroke contains the power of the laws of heaven and earth. With my own abilities, it is indeed impossible to complete it."

"However," Li Muran's heart moved: "I wonder if that mysterious little mirror can also resolve the invisible repulsion force encountered when making the Immortal Runes?"

The mirror light of the mysterious small mirror can resolve the invisible resistance encountered when making talismans. Even if the top runes in this world are illuminated by the small mirror light, it will be much easier to draw.

However, now Li Muran wants to draw the runes of the immortals. It is hard to say whether the mirror light of the small mirror can also resolve the invisible resistance encountered when drawing the runes of the immortals.

Li Muran took out the small mirror and shone the blank jade talismans with the light of the mirror - he often did this kind of thing. After the blank jade talisman was illuminated, it became very smooth when it was used to make the talisman.

After the mirror light shone for a while, Li Muran put away the small mirror and began to try to draw the runes of the immortal family again.

This time it was really different! When the first rune was drawn halfway, the powerful invisible resistance did not appear, and Li Muran was able to successfully complete the first rune.

However, when Li Muran had just completed the first rune, the magic power in his body immediately lost control, and rushed towards the first rune madly, and in an instant, amazing magic power poured in.

However, this immortal rune seemed like a bottomless pit, and was not filled at all, and was constantly absorbing and devouring Li Muran's magic power.

Li Muran was shocked. He wanted to withdraw his magic power, but he could not control it at all!

"Boom!" With a loud bang, a huge ball of fire burst. This jade talisman was limited by its own material and could no longer withstand such a majestic magic power, and exploded on its own.

The huge explosion shocked the solid static room with heavy restrictions and directly smashed it to pieces, and Li Muran's figure was also blown out of the static room.

When the demon soul heard this huge movement, he rushed over, but saw Li Muran in a very embarrassed face, with a charred face.

"What happened? Why did my friend look like this?" The demon soul asked curiously.

Li Muran checked himself and was not seriously injured. He breathed a sigh of relief and said with a wry smile: "I want to try to draw the runes of the immortals seen in the lost world. Who knew that the magic power would be lost and the talisman exploded! Fortunately, I was successful in refining my body, otherwise I would have been blown to pieces!"

"It's so dangerous!" said the Demon Soul: "With my friend's cultivation, it is impossible to comprehend the runes of the immortals, and it cannot control its power. This kind of risky attempt cannot be continued!"

Li Muran shook his head slightly: "This is not necessarily true! In the self-destruction of the talisman just now, it has been seen below that this immortal rune should be a powerful rune with fire attribute. It is just because its power is too strong, so it cannot be controlled. If it can reduce the power slightly, it may be really useful for me!"

"As for this person, I have to take the risk of trying?" The Demon Soul frowned.

"Not bad!" Li Muran nodded firmly: "I will learn from my lessons and take precautions, and there will be no big risks."
