Mortal: I became invincible after becoming sworn brothers with Han Li.

Chapter 181 Mysterious Fire Forging Manual

Li Yunfan's memories contained all of Han Li's later experiences, so he naturally knew what the Golden Jade Book was. This book was indeed a treasure that had been passed down from the Immortal Realm to the Spirit Realm, and the contents recorded on it could only be cultivated by humans.

The entire Golden Palace Jade Book is divided into two pages, inner and outer, totaling one hundred and eight pages.

The inner pages, consisting of thirty-six pages, are written entirely in gold seal script, recording various breathing techniques and supernatural powers of profound transformations.

The outer pages consist of 7,020 sheets, written in silver script, covering a wide range of miscellaneous subjects such as formations, talismans, alchemy, and weapon crafting, making them extremely rich in content.

After learning that the jade tablet in his hand was one of the seventy-two outer pages, he asked Bing'er to examine this half of the Golden Palace Jade Book with him.

Then, based on the sound inside the crystal ball, compare it with the silver tadpole script on the jade plaque.

This process was undoubtedly slow, after all, the silver tadpole script was a celestial script, and even if one knew the meaning of each script on the jade tablet, it was still difficult to understand after studying it.

It took the two of them a full year to finally sort out the runes on the half of the Golden Jade Book.

"The Mysterious Fire Forging Manual—" Li Yunfan murmured to himself, stroking the golden jade book.

His half of the Golden Jade Book contained an extremely profound method of weapon crafting.

There is also a method for crafting a magical artifact called the "Crimson Sky Pearl Heart Sword".

However, because part of the jade tablet is missing, both the "Mysterious Fire Forging Manual" and the "Crimson Sky Pearl Heart Sword" only contain half of the records.

Li Yunfan touched the jade tablet, pondered for a long time, then let out a long breath and murmured.

"The information recorded on this jade tablet is extremely suitable for the Nine Revolutions Burning Heaven Technique. It seems that the reason why Senior Yun Minglan kept it safe was probably because he also had the intention of learning the weapon-refining method on it and refining the magic weapon on it."

At this point, a hypothesis suddenly came to mind.

"Could it be that the news of his possession of this half of the Golden Jade Book was leaked, which attracted his enemies, ultimately leading to his severe injuries and his escape into the depths of the Taiyue Mountains?"

Li Yunfan had this idea because the Golden Jade Book was too precious. He believed that even in ancient times, it would definitely attract the covetous eyes of many powerful cultivators!

After pondering for a moment, Li Yunfan finally brought his thoughts back to the half of the Golden Jade Book in his hand.

According to the "Mysterious Fire Forging Manual", this method of forging weapons requires the use of a flame called "Mysterious Quenching True Flame".

This flame is not naturally born from the heavens and earth, but is condensed by cultivators through cultivation.

What frustrated Li Yunfan was that the method for condensing the "Mysterious Tempering True Flame" was not recorded at all in the half of the Golden Jade Book in his hand, only some scattered descriptions.

"Extreme cold and extreme heat — the convergence of Yin and Yang —"

Li Yunfan frowned as he looked at the descriptions of "Mysterious Tempering True Flame" on the jade tablet, pondering their meaning.

He didn't know how much time had passed until he suddenly heard Bing'er's trembling voice in his ear, which brought him back from his reverie.

"Yun Fan, my chilling energy has erupted!"

Upon hearing this, Li Yunfan did not hesitate at all. He immediately put away the jade token and pulled Bing'er to his side.

At this moment, Bing'er was radiating an extremely cold aura. Her scales were covered with a layer of white frost, her face was pale from the cold, and her body was trembling uncontrollably.

Li Yunfan held Bing'er in his arms, his eyes slightly closed, silently circulating the secret technique of the Hanchi Clan in his mind.

The fire-attribute spiritual energy within his body circulated rapidly, and the three types of spiritual fire formed a triangular shape within his dantian, slowly rotating.

His body gradually emitted billowing heat, and his skin turned bright red, making him look like a red-hot iron rod.

Bing'er, sitting in Li Yunfan's arms, had her eyes closed and was tightly hugging his chest, her snake tail coiled around his waist.

Its scales turned a bright, pure white, as if it were covered in a layer of snow.

At the same time, she was silently practicing the secret method her mother had taught her.

The cold and hot energies within their bodies, under the control of a secret technique, condensed into a unique spiritual energy that flowed continuously through their bodies as their skin touched.

Gradually, the spiritual energy of heaven and earth surrounding the cave began to converge on the two people in the cultivation room.

And under the influence of that peculiar spiritual energy, it was refined into the spiritual power of the two of them.

And their bodies gradually changed during their time practicing together.

After more than ten days, the cold energy in Bing'er's body began to decrease slowly and eventually disappeared.

The peculiar spiritual energy that had been circulating within the two individuals gradually dissipated due to the absence of the chilling energy.

Sensing the dissipation of spiritual energy, the two opened their eyes simultaneously.

However, Bing'er still held onto Li Yunfan tightly and did not let go.

Li Yunfan was used to this, and simply raised his hand to pull Bing'er's arm away, speaking to her with a hint of reproach.

"Have you forgotten what I said? You can't hold me anymore after you finish your cultivation!"

"Hmph, you're so mean! I just did you a huge favor, so what's wrong with letting me hold you a little longer!" Bing'er pouted and said angrily.

Looking at Bing'er's angry expression, Li Yunfan sighed helplessly.

Ever since the other party advanced to the Foundation Establishment stage, it's as if their personality has completely changed.

Previously, Bing'er seemed very shy and always obeyed his every word.

Although the other party is still obedient, she is like a rebellious girl, and she will talk back from time to time.

Especially after becoming a fellow practitioner, he liked to hold onto him tightly and not let go, as if he extremely enjoyed the feeling.

Actually, it wasn't that Li Yunfan couldn't let the other person hold him, but after so many years of cultivating together...

If his body is held for too long, some unexpected abnormalities will automatically appear.

Li Yunfan was certain that his heart was completely sincere and he had no ulterior motives whatsoever.

But his body seemed to have its own thoughts, always putting him in rather awkward situations.

That's why he made demands on Bing'er in order to prevent this from happening again.

Once the fellow practitioner has finished, you can no longer hold him!

"That won't do either. Besides holding you, I can make it up to you in other ways!" Li Yunfan said with a light cough.

Upon hearing this, Bing'er immediately loosened her snake tail with a grin and then said to Li Yunfan.

"Alright, then I want you to forge me a weapon!"

"Weapons?" Li Yunfan was taken aback; he hadn't expected the other party to make such a request.

"That's right, I see that every human cultivator has their own magic weapon, so I want one too!" Bing'er said with a confident smile.

Although Li Yunfan found it a bit strange, he still nodded in agreement.

He happened to have an ice-attribute material in his storage bag, which would be a good choice to use to forge a magic weapon for Bing'er.

Seeing that Li Yunfan had agreed to her request, Bing'er was overjoyed and happily wandered around the cultivation room.

Seeing the other party's expression, Li Yunfan smiled knowingly.

"My cultivation has improved again. It seems that as Bing'er's cultivation increases, the benefits I receive as a fellow cultivator will also be greater—" Li Yunfan thought to himself as he assessed his current cultivation level.

Just as he was once again marveling at the benefits brought to him by the convergence of hot and cold, a flash of inspiration suddenly struck him!

'

"The convergence of cold and heat" — "The extreme of cold and heat" — "The fusion of yin and yang" — "The convergence of yin and yang"
