Everlasting

After that, Chen Nianzhi kept it warm and cultivated for thousands of years, using pure Yang fire day and night to refine it. Only now has 90% of the impurities in it been tempered.

It is quite different when using the Five Elements Essence. The Five Elements Essence is the energy of the Five Elements that is separated from the Five Elements Spiritual Qi when monks practice.

These five elements of energy are the purest essences in the world. Each essence such as Lihuo, Gengjin, and Wutu is separated, and there is no possibility of mixing.

When the five elements essence is used to refine the magic weapon, it is almost impossible for impurities to exist.

In this way, the magic weapon is transparent to the glass, and there is no obstacle under the infusion of immortal energy of the same attribute, so that it can exert its maximum power like an arm.

But just like that, the Five Elements Essence is only the energy of the mortal world. Without the key immortal material, it is not enough to use it to sacrifice the immortal treasure.

So the ancients came up with a way to first collect the essence of the five elements, and then integrate the pure immortal energy they cultivated into it, transforming it into the immortal energy of the five elements.

The Five Elements Essence that Chen Nianzhi received from Qian Xuande was actually the Five Elements Immortal Qi that had been refined through the Immortal Energy Sacrifice, and could be directly used to sacrifice the natal Immortal Treasure.

"Let the sacrifice begin."

Getting back to the topic, Chen Nianzhi looked at the five elements of immortal energy in the dragon-patterned black gold cauldron, and couldn't help but feel slightly certain in his heart.

He took out the Lihuo Guixu Sword, and immediately activated the power of the dragon-patterned black gold cauldron, which began to promote the sword to continuously refine the Five Elements Immortal Qi.

The Lihuo Guixu Sword is like a whale swallowing a vast sea, constantly absorbing a large amount of Five Elements Essence, but it is quite slow compared to this furnace of Five Elements Essence.

This furnace of energy contains three trillions of energy. If it were spread to the world, it would be enough to flood a continent. It would not be a day's work to completely refine it.

Chen Nianzhi spent a full sixty years of training before he successfully promoted the Lihuo Guixu Sword.

"Qiang——"

"What a fairy sword!"

Looking at the Lihuo Guixu Sword in front of him, Chen Nianzhi couldn't help but feel a little happy in his heart.

After the Lihuo Guixu Sword was promoted this time, its entire body became transparent, with purple flames flowing in the sword, and even a hint of the edge that could kill immortals and demons bloomed.

This made him feel happy, because after the Lihuo Guixu Sword was promoted to the middle-grade immortal sword, its power has greatly increased again, and it can be used as Chen Nianzhi's trump card.

Thinking of this, he did not waste time and started to refine the Tianhe Renshui Sword again.

With the experience from the last time, it was smoother this time. It took Chen Nianzhi less than a sixty-year period to successfully promote him.

Both Tianli swords were successfully promoted, and Chen Nianzhi couldn't help but feel slightly certain.

Nowadays, the pair of immortal swords have been promoted to the middle level of immortal swords. Blessed by Chen Nianzhi's unparalleled magic power, the power of the combined strike is probably close to the seventh or eighth level of immortality, which is enough to be his trump card.

It has been more than two thousand years since he became an immortal. He relied on the Hunyuan Immortal Body and several natal magical powers. He was able to defend but not kill enough.

Now that Tianli Shuangjian has been successfully promoted, Chen Nianzhi has more ways to deal with the later stages of immortality.

"When we encounter the Red Flame Divine Eagle Emperor again, we don't need to show off our weakness and attack him in a sneak attack. It should be enough to defeat him head-on."

Chen Nianzhi whispered in his heart and stopped thinking about it.

He put the two swords of Tianli into his Dantian to warm them up, and then took out the Ancient Desolate Dragon Reverse Scale.

This ancient wild dragon reverse scale is an extremely strong fairy material. Whether it is used to refine fairy swords or to sacrifice defensive fairy treasures, it is an excellent treasure.

Chen Nianzhi feels that this treasure has extremely high resistance to all kinds of alien energy. If it is made into a defensive fairy treasure, its defensive ability may exceed its original grade.

However, this reverse scale is too strong, and even Qian Xuande in the late stage of ascending to immortality cannot refine it. Therefore, for many immortals, it is a waste that is tasteless and discarded.

Chen Nianzhi practices the Hunyuan Wuji Law. Based on these laws, the power of Pure Yang Sky Fire is far beyond what ordinary immortals can compare, so he took this scale to try it.

Now he said that the ancient wild dragon's reverse scale was put into the black gold cauldron with dragon patterns, and he began to activate the pure Yang sky fire to continuously refine the reverse scale.

Time flies so fast, Chen Nianzhi activated the Pure Yang Sky Fire to refine it for a full hundred years, but found that the Ni Lin had not changed at all.

"No, how can it be so strong?"

At this time, Chen Nianzhi's face couldn't help but look extremely solemn.

The temperature of his Pure Yang Sky Fire is so high that it can refine even high-grade immortal treasures. Unexpectedly, he can do nothing about this reverse scale.

"Maybe I found a treasure."

Chen Nianzhi was happy, but also a little helpless.

This reverse scale is not only extremely strong, but its resistance to laws and flames is also ridiculously high. If it can be refined into a protective magic weapon, it will definitely be used as a true protective treasure.

In fact, Qian Xuande thought the same way when he got this treasure, and wanted to refine it into a protective fairy treasure.

However, this treasure was solid and immortal. Qian Xuande spent hundreds of thousands of years researching it, but was still unable to refine it. Seeing that it had no power of law, he had no choice but to sell it to Chen Nianzhi.

"Is it really not possible?"

Chen Nianzhi shook his head helplessly, and couldn't help but have the idea of ​​giving up temporarily.

But at this moment, the black gold cauldron with dragon patterns suddenly glowed, and the vivid dragon patterns trembled. Countless law dragon patterns suddenly flew out and poured into the reverse scale.

At the same time, Chen Nianzhi's Pure Yang Sky Fire also increased several times in the cauldron, and he began to madly and proudly refine the Desolate Dragon Reverse Scale.

In the midst of such changes, the reverse scale slowly softened and finally turned into a mysterious substance with the color of pure gold.

"It's done."

Seeing Ni Lin being refined, Chen Nianzhi couldn't help but feel a little happy.

But he took out the Wutu Zunhuang Bell, put it into the black gold cauldron with dragon patterns, and began to continuously incorporate supernatural substances into it.

I don’t know how long it took, but the Wutu Zunhuang Bell flew out from the dragon-patterned black gold cauldron, flew up into the sky and began to survive the thunder tribulation.

This Wutu Zunhuang bell, which is made from the inverse scales of the wild dragon, is really extraordinary, and the thunder calamity of the Immortal Treasure is constantly roaring in the sky.

The Wu Tu Zun Emperor Bell stood there calmly, bathed in the lightning disaster that destroyed the heaven and earth, but it never moved at all, and only the sound of the bell echoed between the heaven and the earth.

"It's done!"

When Wutu Zunhuangzhong was successfully promoted, Chen Nianzhi finally breathed a sigh of relief.

He took the Wu Tu Zun Emperor Bell in front of him and found that the appearance of this natal immortal treasure changed drastically. Not only did it change from pure gold to dark yellow, but there were also dragon patterns coiled around it.

"It seems that it might be more appropriate to call this treasure Panlong Bell."

Chen Nianzhi's heart moved slightly and he couldn't help but whisper like this.

The thoughts in his mind fell, and he turned back to look at the dragon-patterned black gold cauldron beside him.

The cauldron remained silent, as if the previous change had not happened at all.

This dragon-patterned black gold cauldron has no weapon spirit, but just now it evolved the dragon pattern on its own, helping him refine the reverse scales of the ancient wild dragon. This magical feature is too mysterious.

Chen Nianzhi pondered in his heart, feeling more and more mysterious that the dragon-patterned black gold cauldron was mysterious, but he still couldn't figure out its origin.

"This dragon-patterned black gold cauldron seems to be more than just a top-quality fairy treasure."
