There are many secret places in the cultivation world that cannot be easily broken into, and once a forbidden formation is touched, the dangers encountered are not something that can be easily dealt with.

Even with such a strong lineup of the Jiuding Sect, it took a lot of effort to kill these Naga guards who were sealed from the stone statue.

"The golden armor and heavy tridents of these Naga guards are considered medium-grade magic weapons, and ordinary monks would be overjoyed to see them, but unfortunately we don't need them. Xie Lingtian sighed.

The golden armor and tridents left behind by the thousands of Naga guards were not good to take away, and it was not convenient to put so many things in the storage bags that were not very important.

It can be said that these things are tasteless to eat and a pity to discard.

"I've heard that you can smelt these demonic artifacts with Nether Fire, and extract the essence from them to obtain very precious refining materials. Dongzi Road.

"It's a pity that I cultivate pure yang true fire, and although it is very powerful, I can't smelt these things. Xie Lingtian sighed with emotion.

Lin Feng pondered for a moment and said, "You reminded me that although I don't have the Nether Fire, I still have a way to smelt the golden armor and tridents that are all over the ground. ”

So he flipped over and took out the Purple Lightning Yin Thunder Knife and another long sword with a powerful purple electric light from the storage bag.

Among all the people present, the ogre powerhouse was very familiar with this long sword containing the power of thunder, and it was in the Gu Immortal Cave Mansion enchantment that Lin Feng was guarding at the beginning, and he obtained this sword, which was called the Cloud Splitting Sky Thunder Sword.

According to the classics left by that Gu Immortal, the Cloud Splitting Sky Thunder Sword is actually a complete set of spiritual weapons, each of which has just been refined and has a quality close to that of a low-grade spiritual weapon, if you collect eighteen of them, you can cast the Cloud Splitting Sky Thunder Sword Array, which is comparable to a high-grade spirit weapon!

At the beginning, in that cave enchantment, due to the instructions left by the Gu Immortals, Lin Feng could only take one of the Cloud Splitting Sky Thunder Sword, and if he wanted to get this kind of sword again, he had to refine it according to the secret techniques in the remaining classics.

The most critical material, Tianlei Bamboo is difficult to find, so let's ignore it for the time being.

In addition, more materials are needed to quench the essence of gold and iron in the purest form, and thunder belongs to the gold of the five elements, so it is very suitable to use the power of thunder to quench the gold and iron essence of gold and iron in the magic weapon.

"Lin Feng, could it be that you want to use the Purple Lightning Yin Thunder Sword and this long sword with lightning to refine the golden armor and trident?" Xie Lingtian wondered.

"Elder Xie, you are only right, you are using this Cloud Splitting Heaven Thunder Sword, and the Purple Lightning Yin Thunder Sword is just a sacrifice, just an introduction. Lin Feng said indifferently, and then the essence and blood energy in his hand swelled, and he operated his strength according to the method in the ancient books.

The purple lightning above the Purple Lightning Yin Thunder Knife was like many snakes circling and writhing, sneering, very crazy and wanton.

"Click~"

Because the thunder and lightning on it were too strong, the Purple Electric Yin Thunder Knife, which was itself a top-grade magic weapon, could not withstand it, so it cracked open and turned into fragments in the sky.

And the thunder and lightning that lingered in it were like a python that had been released, rushing out wildly around.

The others hurriedly surged up their body protection qi to avoid being accidentally injured by lightning.

Lin Feng's expression was calm, and according to the method of refining weapons in the ancient books, he methodically coordinated with essence blood energy and spiritual power, controlling the fragments of the sword body and the purple lightning in the sky.

The golden armor and heavy tridents scattered on the corpses of the Naga guards on the ground were all good metal magic weapons, and they had a good sense of power with purple lightning, so they quickly sank into it.

The power of thunder in the void was only a little large at first, and it was relatively disordered, and then Lin Feng used secret techniques to guide, and the Cloud Splitting Sky Thunder Sword was suspended in front of him, emitting a dazzling purple thunder lightning, and then hovered in the void.

With this as the center, many lightning bolts spread out around it, and thousands of golden armors and tridents were tempered by this domineering thunder.

Using this refining method was a huge drain on Lin Feng's spiritual power and essence blood energy, but he had to grit his teeth and hold on.

Later, the power of thunder was still not enough to smelt the essence of gold and iron in the golden armor and trident, and Lin Feng had all the understanding in his heart, and in front of his trusted teammates, he no longer hid the spirit weapon of the Fire Immortal Lotus.

A dazzling red light flickered, and the Flame Immortal Lotus was suspended in the void, spinning and rapidly differentiating into three identical red lotus flowers, and then rapidly spinning, emitting many flying knife-like lotus petals.

A moment later, the lotus petal flying knives splattered around like a storm, and the void was reflected red.

What made it difficult for the teammates to understand was why the three crimson lotus flowers suspended in the void could send out so many lotus petal flying knives, as if they were endless.

"To be able to achieve such a powerful and powerful function, this must be a spiritual weapon, and the quality is still very high, it is not a low-grade spiritual weapon, I didn't expect Lin Feng that you still have such a treasure!" Elder Xie Lingtian said in surprise.

The disciple had such a precious treasure, and he was sincerely gratified, rather than having ulterior motives.

The lotus petal flying knives emitted by the Flame Immortal Lotus turned into clusters of pure flames and sank into the golden armor and trident, producing a drastic change together with the large amount of thunder and lightning generated by the Split Cloud Sky Thunder Sword that had previously submerged inside.

Gradually, the golden armor and tridents on the corpses of thousands of Naga guards shattered inch by inch, and scattered elite points of light flew out of them, which were the essence of gold and iron.

Lin Feng carefully controlled the Split Cloud Sky Thunder Sword to gather the crystal light points flying in the sky, and after a while, he finally gathered all the light points together, and in front of Lin Feng, there was a golden grinding disc suspended in front of him.

"In the future, if you find the Heavenly Thunder Bamboo, you can use the essence of gold and iron to refine it into the Cloud Splitting Sky Thunder Sword. This piece of gold grinding disc is enough to make another seventeen pieces!" Lin Feng said in his heart.

"Brother Lin Feng, it's really a good means, I can't see through you more and more. Li Zhou exclaimed.

"Don't see it, this Flame Immortal Lotus and the Cloud Splitting Sky Thunder Sword are all things that I got by chance from my experience outside, and you will also gain something in your future training, so why worry. Lin Feng smiled indifferently.

He was telling the truth, only by practicing outside could he have more chances to obtain rare treasures. The cultivation obtained behind closed doors often has no actual combat ability, and can only be reduced to a laughing stock.

"Lin Feng, you have smelted the essence of these tens of thousands of pairs of golden armor and tridents guarded by Naga and turned them into this piece of golden grinding disc, and even it itself is equivalent to a low-grade spirit weapon, but it has not yet produced a tool spirit. Xie Lingtian said with a smile.

"This golden grinding disc can also be regarded as a low-grade spiritual weapon, it is so rough, it has not been refined!" Lin Feng said with some surprise.

"Don't underestimate this golden grinding disc, I know that you want to use it as a precious refining material, but before you collect all the materials to refine, this grinding disc can be taken out for battle. Xie Lingtian said with a smile, "We happen to have a book in our Jiuding Sect that is suitable for cultivation by the Nine Golden Pill realm cultivators, called 'Qiankun Great Mill Plate', I thought this Xuangong was interesting back then, so I rubbed it in a jade slip, do you need it?"

"I'm also about to break through to the realm of the Nine Golden Pill of Blood Condensation, and there is such a golden grinding disc in front of me, which is very suitable for cultivating the Xuangong of the 'Qiankun Great Mill Plate' you mentioned! Lin Feng smiled.

Elder Xie Lingtian was indeed a very upright person, although he usually looked chic and uninhibited and had a very young mentality, he was actually very reliable at many critical moments. The most important thing is that he puts most of his mind on thinking about his disciples.

So, Xie Lingtian turned over and took out a pair of jade slips from the storage bag and handed them to Lin Feng.

Receiving this jade slip in his hand, Lin Feng probed his spiritual power into it, and the light and shadow of the words came to his face, although he couldn't see these handwriting clearly for a while, but that thought had been deeply imprinted in Lin Feng's mind.

Lin Feng closed his eyes, pondered and deduced the cultivation method of the Xuangong of "Qiankun Great Grinding Plate" in his mind, and deeply understood it, his martial arts talent has made a qualitative leap in the continuous accumulation of actual combat, and the speed of deriving martial arts is more than ten times that of ordinary monks, and he can often think of the key points quickly.

Elder Xie Lingtian and his teammates were quietly waiting for Lin Feng to comprehend this Jindan-level Xuan Gong, after all, this was a high-level Xuan Gong, and it was difficult to cultivate.

Even a monk who has reached the realm of the Blood Condensation Ninefold Golden Pill may not be able to successfully cultivate this "Qiankun Great Mill Plate" Xuan Gong in ten days and a half months, because this is a very remote Xuan Gong, and there is almost no experience of predecessors to refer to.

For example, in the practice of kendo, there are many similar swordsmanship and Xuangong, which can be bypassed, used for reference, and avoid detours.

Everyone thought they were going to stay here for a long time, but after an hour, Lin Feng opened his eyes and deeply understood the mystical skill of "Qiankun Great Mill Plate" from meditation.

"Lin Feng, this Xuangong is very esoteric and remote, you have a rough understanding of its basic situation in this hour's time, and when you get to Kunlun Ruins, if you have time, you can cultivate slowly by yourself, don't be in a hurry for quick success, so that you go crazy. Xie Lingtian patted Lin Feng on the shoulder and said earnestly.

"Elder Xie be careful of this golden grinding plate!" Lin Feng comprehended this Xuan Gong, and his heart was eager to try, and with a move of his hand, he summoned this suspended golden grinding plate.

Then, according to the luck method of this Xuangong, the golden millstone turned into a golden light and smashed away.

As a peerless master of the Transformation Realm, Xie Lingtian felt this momentum of being incomparably powerful and destroying all things at this moment, and he couldn't help but dodge carefully.

"Qiankun big grinding plate!"

Lin Feng's two-handed magic tricks changed, controlling this golden grinding disc to constantly roar out, the tricks opened and closed, and the indomitable momentum also ran through the tricks.

He had already infused his indomitable martial arts style into this Xuan Gong.

In the powerful golden light in the sky, Elder Xie Lingtian dodged with agility and swiftness, often the golden grinding disc smashed down, destroying a building, and there were countless deep pits on the ground, which was shocking.

A moment later, the palaces under the sea were almost destroyed.

Elder Xie Lingtian let out a long roar: "Natal Beast Soul, Transformation Vermilion Bird!"

The mark of the firebird in the center of his brow bloomed red, and then a huge firebird flew out, like a phoenix.
