The Tianwen Nine Remnant Furnace appeared, and the coffin-shaped furnace body was extremely heavy, and it landed with a loud noise.

Swish!

Throw the sword directly into the furnace, urge the emperor fire, and the flame in the furnace will burn instantly....

The materials needed for refining the weapon, Chu Yan had already collected all the materials in the Imperial Sect's treasure house, and there was no shortage at all.

A pile of refining materials, plus 30,000 yuan crystals, was immediately put into the furnace, which suddenly made the flames in the furnace dim, Chu Yan hurriedly urged the true qi, maintained the strength of the flames in the furnace, and began to refine the Haotian Sword!

The fifth order to the sixth order is very difficult, far exceeding the sum of all the previous upgrades, however, after Chu Yan used the "Tianwen Nine Waste Furnace" to refine a large number of pills, now there seems to be some kind of mysterious connection between him and the Tianwen Nine Waste Furnace, for the entire refining process, even if he doesn't need to be probed by his divine sense, he can sense it clearly.

Therefore, Chu Yan could completely use this mysterious induction to ensure that there would be no problems with the promotion of the Haotian Sword.

Even if the promotion failed, Chu Yan would interrupt the refining as soon as possible and take back the Haotian Sword so that it would not be scrapped directly.

With this, Chu Yan dared to refine boldly without too many scruples!

The Haotian Sword was in the furnace, constantly trembling, and all kinds of refining materials, under the guidance of Chu Yan's divine sense, continued to merge into the sword body.....

Chu Yan's divine sense was like a net, tightly wrapping the entire Tianwen Nine Remnant Furnace, nervously watching any change in the furnace.

Time flies and the temperature in the room keeps rising.....

Soon, three hours, in the blink of an eye!

Boom!

The loud sound of the sword pierced through the heavens and the earth, as if above the sky, a thunderclap .....

The Haotian Sword that rushed out of the furnace was snow-colored all over its body, exuding ten thousand silver rays, like a round of silver Haoyue, and the sword body exuded a monstrous atmosphere, as if the sky was suppressing the heavens......

"Good! Good sword! ”

Chu Yan raised his hand and summoned, held the Haotian Sword in his hand, and with a wave of his hand, a silver sword light spilled out, and a foot-long void crack suddenly appeared in the void in front of him, and the incision was smooth, as if a hot knife had cut through butter....

With this sword, Chu Yan did not use a trace of true qi, and completely relied on the sharp sword qi of Haotian Sword itself.....

"With this sword, how can the world's spiritual soldiers compete!? Hahaha....."

Chu Yan held the Haotian Sword in his hand, and felt the sharp chill on the sword body, causing the surrounding void to continue to tear, and he immediately laughed out loud.

Although he didn't know what the spirit weapon Ye Feng used was and what quality it had achieved, Chu Yan believed that the Haotian Sword in his hand would definitely not lose to the other party.

"Next, it's time to lock the robe!"

Chu Yan waved his hand, put away the Haotian Sword, picked up the lock robe next to him, groaned slightly, and threw it into the Tianwen Nine Remnant Furnace.

Compared to the Haotian Sword, Chu Yan had already refined it six times, and he had been using it to fight, so it could be said that he was familiar and could not be more familiar, so he dared to refine it boldly with confidence.

And this lock robe, Chu Yan has not been in contact for a long time, although he is amazed by its anti-heaven defense ability, but when it comes to refining and upgrading, his heart is still a little bottomless, if he accidentally refines it into a waste product, it will be too late to cry!

"I hope to go all the way up to the fifth rank!"

Chu Yan looked at the Lock Heaven Robe in the furnace, although he was a little reluctant in his heart, but he thought that the fifth-order Lock Heaven Robe, I am afraid that even a half-step Martial Venerable Realm powerhouse would not be able to break through its defense, and when fighting against Ye Feng, this would definitely become the most important hole card.

Finally, Chu Yan gritted his teeth fiercely, and with a wave of his hand, he swung the Vermilion Bird Emperor Fire into the furnace, and the fire was ..... majestic!

The materials used in refining the Lock Heaven Robe were extremely complex, and Chu Yan had invested thousands of refining materials in the next two hours before he had raised the Lock Heaven Robe to the fourth order!

At this time, the Lock Heaven Robe, which was originally covered in black, actually rose a trace of dark golden brilliance, and at the same time, the faint power of the stars continued to overflow from the Lock Heaven Robe....

The power of the stars, absorbing the essence of the heavens and stars, and integrating it into the Heavenly Lock Robe, greatly improves its defensive performance.....

Facing this Heavenly Lock Robe, Chu Yan suddenly felt that he wanted to break through its defenses, as if he wanted to break through the starry sky of the Stars and Heavens, and his heart was full of powerlessness!

"What a robe! But now, do you want to go up to the fifth order!? ”

Looking at the locking robe full of the power of the stars in front of him, Chu Yan became more and more reluctant in his heart.....

You must know that now this fourth-order Lock Heaven Robe can completely ignore the attacks of any martial artist below the Martial Venerable Realm, which is almost equivalent to the existence of the "Invincible Spirit Treasure" in the Tongtian Realm!

This piece of treasure, in the hands of any sect or strong person, it is too late to cherish it, how can it be used for refining, it is not careful, it will directly turn into a pile of black ashes!

Looking at the suspended Heavenly Robe in front of him, and then at the Tianwen Nine Remnant Furnace in front of him, Chu Yan's face was full of struggle!

Whoa!

With a wave of his hand, Chu Yan took out all the refining materials for refining the sixth-order locking robe.

More than 600 kinds of materials, covering the entire room floor!

Immediately, Chu Yan spent half an hour carefully checking and classifying each material to ensure that it was foolproof and accurate!

"Sixth-Order Lock Heavenly Robe, success or failure in one fell swoop!"

Chu Yan took a deep breath, if it wasn't for dealing with Ye Feng, of course he didn't have to take risks, but in order to improve the probability of defeating Ye Feng, even if it was a slight possibility, Chu Yan would have to fight!

After pondering for a moment, swallowing the next Nine Xuan Golden Pill, Chu Yan began the formal refining!

The difficulty of refining the fifth-order Locking Heaven Robe was far beyond Chu Yan's imagination, with nearly six hundred kinds of materials, it took a whole night just to refine and fuse them into the Locking Heaven Robe.

The next morning, when the East was white, the refining was finally over!

Chu Yan, who was sitting in front of the Tianwen Nine Remnant Furnace, was covered in sweat, his whole body was soaked, his whole face was pale, and his breath was extremely weak!

He never thought that the refining of the fifth-order locking robe would take such a long time.

Although the difficulty of refining is simpler than that of Haotian Sword, the materials and time required are really terrifying!

The entire three bottles of the Nine Xuan Golden Pill were all exhausted in the second half of the night, and later, Chu Yan completely relied on the true qi of the sixteen Inner Pills to support him, and finally completed the refining of the fifth-order lock robe at dawn!

Chu Yan, who breathed a long sigh of relief, quickly got up, went to the room next to him, and after taking a bath, changed the fifth-order lock robe on his body.

In an instant, the majestic power of the stars lingered around his body, making Chu Yan faintly feel like he was integrating into heaven and earth, and his face was suddenly full of joy!

"Good! It is worthy of a fifth-order lock heavenly robe, hehe, even if Ye Feng's cultivation reaches the half-step Martial Venerable realm, I am not afraid! ”

After returning to the cultivation room, Chu Yan flipped his hand, took out a bottle of "Guiyuan Dan", smiled bitterly, shook his head, swallowed the Guiyuan Dan, and began to recover his true qi.

By now, the Nine Xuan Golden Pill had all been consumed, and Chu Yan had to recover his true qi and start refining again!

........

A day later, when Chu Yan stepped out of the cultivation room, his whole body was completely renewed!

"Ye Feng! You wait, I'm Chu Yan here! ”

His eyes narrowed slightly, his eyes were like thunder, and on Chu Yan's body, the violent battle intent rushed straight to Yunxiao.....

Immediately, Chu Yan strode towards the Earth Sect Hall.
