I saw that among the Nine Heavens Essence Gold, the Divine Wood Spiritual Heart, the Xuanyin Earth Fire, and the Ten Thousand Years Cold Spring placed on all sides, each of them had a bright brilliance slowly rising and condensing, and through the mutated eyes, Chu Han could still see that countless star powers began to rise from the Taiji Diagram, and converged towards the four clusters of brilliance that slowly rose.

"Give me the dragon horns!" When Ou Li saw the abnormality, he immediately shouted at Chu Han.

The long earth dragon horn appeared in Chu Han's hand in an instant, and then quickly threw it towards Ou Li.

Ou Li caught the dragon horn thrown by Chu Han with one hand, and then walked quickly to the center of the four holy relics, and then thrust it heavily.

The Divine Dragon Horn was like a sharp sword, inserted into the black earth in an instant, and then, Oli quickly ran out and returned to Chu Han's side.

"That's good? What kind of spiritual array is this? Chu Han looked at the scene in front of him and asked curiously.

"Of course it's not good, it's still foreplay, it's just warming up the four spirits!" Oli shook his head slightly and replied lightly.

"What do you mean by warming the four spirits?" Chu Han asked with a frown.

"This is the four elephant spirit arrays built by borrowing the four holy relics of Xuanyin Earth Fire, Ten Thousand Years of Cold Spring, Nine Heavens Essence Gold, and Shenmu Spiritual Heart, creating the Eastern Wood Spirit Green Dragon with the Shenmu Spiritual Heart, gathering the Southern Fire Spirit Vermilion Bird with the Xuanyin Earth Fire, refining the Western Golden Spirit White Tiger with Nine Heavens Pure Gold, and freezing the Northern Water Spirit Xuanwu with the Ten Thousand Years of Cold Spring. After the formation of the four spirit elemental bodies, it's up to you! Oli looked ahead and said solemnly.

"Oh? What should I do? Chu Han was also a little apprehensive at this moment, looking at the four clusters of light slowly gathering in front of him, and asked seriously.

Ou Li glanced at Chu Han and said solemnly: "Next, you must remember what I said. After a while, you will enter the Four Elephant Yuan Spirit Array and sit next to the Divine Dragon Horn. Then, with the power of your own spirit, you can attract the four elephant spirits and merge them into the dragon horn. ”

After a pause, Oli slowed down his speech and continued: "First of all, you have to first attract the power of the Southern Fire Spirit Vermilion Bird, and then throw the dragon horn into the top of the Xuanyin Fire Cave, and melt the dragon horn with the power of the Vermilion Bird, and after it is completely melted, you will cover the melted dragon horn juice on the Western Golden Spirit. Let the dragon horn juice and the Nine Heavens Essence Gold completely fuse, at this time, you remember, if the Dragon Horn Juice and the Nine Heavens Essence Gold cannot be melted, at this time, you have to migrate the Fire Spirit Vermilion Bird over, fire gold, and use the power of the Vermilion Bird to accelerate the fusion of the Nine Heavens Essence Gold and the Dragon Horn. ”

"When the merging begins, you'll have to take the opportunity to complete the forging with your mind. Depict the shape of the weapon. After the weapon carving is completed and the Nine Heavens Essence Gold and the Divine Dragon Horn are completely fused, then the tempering of the Northern Water Spirit Xuanwu will be required. At this time, you have to throw the holy soldiers into the cold spring of ten thousand years. Quenched with the power of the cold spring for thousands of years, when the tempering is completed and the weapon is formed, it needs to be warmed by the spiritual heart of the divine wood with the power of the wood system. By the time the curing is completed, basically, the entire casting procedure is almost complete. Oli said slowly.

"What do you mean by nearing completion? Isn't that the last step? Chu Han looked at Ou Li. I couldn't help but ask again.

"The last steps, there may or may not be, when the time comes, you have to resign yourself to fate! Alright, the spirit of the four elephants is almost condensed, let's get ready to enter! Oli looked at the four light clusters below and said solemnly.

Chu Han then looked down, and sure enough, at this moment, above the Xuanyin Earth Fire, a Flame Divine Bird with wings spread and flying was constantly circling around the Xuanyin Fire Cave, and above the Divine Wood Spiritual Heart, the green brilliance slowly turned into a green green dragon about two or three meters long.

Above the cold spring of ten thousand years, the white mist is rising, faintly visible, and the head of a huge turtle and snake lies on the water, which is exactly the appearance of Xuanwu in the legend. Similarly, at the top of the Nine Heavens Essence Stone, a huge white tiger prostrated on it, exuding a sharp aura of slaughter all over its body.

At this moment, Chu Han slowly walked towards the Four Elephant Yuan Spirit Array, and without taking a step, the aura on Chu Han's body was all stronger, and at the same time, the divine dragon blood in his body was constantly boiling, and slowly, a powerful aura began to permeate the entire space.

When Chu Han walked to the side of the Divine Dragon Horn, the aura around Chu Han's body also swelled to the extreme, and in an instant, a golden flame began to burn in Chu Han's pupils, and the golden aura around his body was surging, and an incomparably powerful aura appeared in Ou Li's heart.

"He's really strong!" Ou Li couldn't help but think of it in shock at this moment, and at the same time, his confidence in Chu Han couldn't help but increase a little bit.

"Go!"

At this time, Chu Han's right hand lightly pointed, and the Divine Dragon Horn that was originally inserted in the soil suddenly flew into the sky at this time, and then quickly rushed into the Xuanyin Fire Cave.

As soon as he entered the fire cave, Chu Han felt as if he was in the flames himself, and a violent and irritable aura surrounded him, which seemed to be the breath of Xuanyin Earth Fire.

Subsequently, Chu Han divided a part of his spiritual power to control the Divine Dragon Horn, while the other part of his spiritual power began to attract the power of the fire spirit in the Xuanyin Earth Fire and began to spread towards the horns of the Divine Dragon Horn.

It seemed to be driven away by Chu Han's strength, and the Vermilion Bird Fire Spirit, which had been hovering above the Xuanyin Earth Fire, suddenly stopped its body at this time, and then flapped its wings and stopped in mid-air, and at the same time, a purple-black flame shot out from the Vermilion Bird's mouth and fell on the body of the Divine Dragon Horn, and at the same time, the Xuanyin Earth Fire Cave below seemed to be invisibly agitated, and it became more violent in an instant, and it also began to burn violently around the Divine Dragon Horn.

"There's a play!" Seeing the changes in the Xuanyin Earth Fire, Ou Li, who was standing on the sidelines and watching, thought of a little surprise in his heart at this moment.

And Chu Han in the Four Elephant Yuan Spirit Array slowly crossed his knees at this moment, and then continuously used his spiritual power to control the fire spirit and Xuanyin Earth Fire in the Xuanyin Fire Cave in front of him, and began the great cause of melting the Divine Dragon Horn.

Time passed minute by minute, although the flames and fire spirits in the earth fire were struggling to swallow the flames, burning in the flames of the dragon horn, but what was helpless was that the dragon horn did not change in the slightest.

"Could it be that this is really the Divine Dragon Sacred Horn? Even with the strength of the legendary Xuanyin Earth Fire, can't it be quickly fused? Seeing that the dragon horn in the flames did not change in the slightest, Ou Li, who had been paying attention to it from the side, couldn't help but show a look of shock on his face.

To be honest, although he recognized Chu Han's statement of the dragon horn before, he still had a little doubt in his heart, after all, no one had ever seen the real dragon, and the existence of the so-called dragon that occasionally appeared was just some demon beasts that resembled the dragon, such as Jiaolong, or Ying Long and the like, although the appearance was similar to the dragon, but in the final analysis, it was not a dragon, it could only be said to be a dragon-like beast, and in Oli's heart, the dragon horn in Chu Han's hand was likely to be the dragon horn of a high-level dragon-like beast. It's just that Chu Han mistakenly thought it was a divine dragon.

But judging from the current situation, this so-called dragon horn is really extraordinary!

Xuanyin Earth Fire is the essence of Earth Fire, which is not inferior to the legendary Zixiao Heavenly Fire. At the beginning, the flame used in the casting of the Xuanyuan Sword was the Zixiao Heavenly Fire, but the Zixiao Heavenly Fire was extremely rare, and without super strong cultivation, it was difficult to intercept it from the sky. And now, even this powerful Xuanyin Earth Fire has been unable to melt this Divine Dragon Horn for a long time, and the fire refining alone is so difficult, Ou Li's heart can't help but feel a bad feeling.

Perhaps, he really overestimated himself and Chu Han. When Xuanyuan Yellow Emperor cast the Xuanyuan Sword, he was already one of the few top powerhouses, and the ancestor of the first line of soldiers was definitely not an ordinary person, and at that time it was in the ancient era, the heaven and earth were abundant, no matter what the conditions were, they were far beyond now, are they really a little overwhelmed with Chu Han?

"Alas, Chu Han, I just hope you can survive this hurdle!" Ou Li finally glanced at Chu Han, who was still quietly tempering there, and said with a sigh in his heart.

At this time, Chu Han, who was in the Four Elephants Fire Spirit Array, also began to slowly feel the crisis. The burning of the Xuanyin Earth Fire was not only melting the Divine Dragon Horn, but also burning Chu Han's spirit.

Chu Han controlled the Divine Dragon Horn and the Fire Spirit Vermilion Bird like this, and his spirit was constantly eroded by the Xuanyin Earth Fire, which made Chu Han's spirit consume extremely quickly. The divine dragon blood in his body continued to decompose and transform into surging star power, nourishing Chu Han's body and mind, but this still couldn't catch up with the speed of consumption.

What's more, at this moment, the Divine Dragon Horn in the Xuanyin Earth Fire did not change at all, as if he was not afraid of the burning of the Xuanyin Earth Fire at all. If this continues, even if Chu Han finally controls the Xuanyin Earth Fire to melt the Divine Dragon Horn, he probably won't have enough spiritual power to complete the other steps.

"Is it really going to be like this?" Chu Han couldn't help but think of it in his heart at this moment, but then he stabilized his emotions, and then continued to decompose the divine dragon blood in his body, quickly supporting the consumption of his body.

By now, he had no choice but to fight to the death. If you don't succeed, you will be benevolent!

And at this moment, neither Chu Han nor Ou Li noticed that on the high mountain wall behind them, the mountain wall that was normally as smooth as a mirror slowly softened, and then slowly turned into a strange human face, looking coldly at Ou Li and Chu Han below.

"Hehe, what an ignorant little guy, such a low-level cultivator, he even wants to use the Xuanyin Earth Fire and the Ten Thousand Years Cold Spring!" At this moment, an ethereal voice suddenly sounded in mid-air, but unfortunately, Chu Han and Ou Li, who were below, didn't seem to have noticed anything, and they were still sitting there intently.
