Time passes again.

Another hundred years.

Two hundred years, three hundred years......

500 years, 1,200 years......

Qin Tian and the Soul Devouring Holy Beast and other ten powerhouses, I don't know how many times they rested during the period.

After all, the power of the world is no match for mana, and it can be made up for with pills or immortal realm yuan power.

Every time Qin Tian's body consumed a huge amount of the power of the Cave Heaven World, they would stop, and then spend decades recondensing the power of the world, and then infuse the power of the world into Qingjiao's body.

In this way, the time spent is more and longer.

In fact, condensing a medium-grade Dao weapon into a high-grade Dao weapon, even if it is exchanged for ten powerful powerhouses of the Spirit Slashing Realm, the time it takes will also require so much.

And when the time passed by fifteen hundred years.

That huge Blood Dragon Crystal Peak.

Originally, it was as red as blood, but at this moment, it had turned into a transparent stone, and the Heavenly Dragon Essence Blood inside had been completely extracted.

All of them were fused into themselves by the frogs.

At this time.

The aura emanating from the frog's body was already terrifying to the extreme.

It was still hovering there quietly, but there was a terrifying aura like destroying the world and destroying the earth, it was a very terrifying momentum, comparable to Shen Yun Gongzi's high-grade Dao Weapon Zixiao Dragon Bed.

If you can see it.

You will see that the cave world in its body has been completely condensed and formed.

"It's time!"

Qin Tian suddenly let out a loud shout, and then he and the Soul Devouring Holy Beast and other powerhouses suddenly changed their handprints.

Thundered!

The constantly changing handprints immediately made this Ten Directions Heavenly Dragon Refining Array feel like a tornado storm was swept inside.

Roar Roar Roar ......

The majestic voice of the Heaven-Shaking Dragon roared loudly, and I saw that inside the formation, a red ball of light suddenly appeared, and a vast energy fluctuation to the extreme emanated from it.

This ball of light is the star core.

Then, this star core slammed into the frog's body.

A terrifying shock wave rippled open, shaking everyone's bodies again and again.

Seeing this, everyone hurriedly stabilized their figures, and then the handprints changed again.

In the entire large array, the sound of dragon groans became more frequent, and more Heavenly Dragon Phantoms appeared, and then fiercely converged towards the frogs.

Qin Tian knew that this was the last moment, as long as the Frog Jiao refined this star core, then it would be able to completely step into the level of a high-grade Dao weapon.

And this time, it doesn't take that long!

When another hundred years have passed!

A certain moment.

Rumble!

Suddenly.

Fierce.

The frog suddenly opened her eyes.

The space seemed to pause, and then, an even more terrifying aura swept out of its body.

Except for Qin Tian, the Nine Realm King Realm powerhouses such as the Soul Devouring Holy Beast turned slightly pale, and their bodies shook violently, and their bodies were directly shaken apart.

This refining array also announced its dissipation in an instant.

However, Qin Tian's eyes were full of essence.

The frog's body moved suddenly, and the entire internal space of the Peak of Time and Space was violently shaking, as if it couldn't bear the aura emitted by the frog and was about to shatter.

Qin Tian smiled slightly, he suddenly stretched out his hand and shouted softly: "The knife is coming!"

Airplanes!

As these two words fell, the body of the Heavenly Dragon, which was still hundreds of zhang in size just now, suddenly burst out with a brilliant golden ray, and then its body shrank suddenly, and in an instant, it turned into the appearance of a knife.

Frog Dragon Knife!

The knife, the same knife as before.

But the color on the surface has changed from gold to purple gold.

The runes above became more esoteric, and faintly, there was a breath of the world rippling out.

On the hilt of the knife, a jewel-like bead with a red glow is embedded in it.

At first glance, I thought it was just a gemstone, but if you feel it carefully, you will feel that the energy contained in this red bead is simply earth-shattering.

This red bead is the star core.

Now, it has been completely fused by the Frog Dragon Knife and inlaid on it!

The blade of the knife hummed slightly, and a wave of joy and excitement rippled out of it.

Top-grade Dao device, big dragon knife!

That's right, at this moment, this big dragon knife has finally transformed from a middle-grade Dao weapon into a high-grade Dao weapon, and the grade is already comparable to Shen Yun Gongzi's high-grade Dao Weapon Zixiao Dragon Bed.

"Congratulations to the host, congratulations to the host ......"

The Nine Realm King Realm powerhouses such as the Soul Devouring Holy Beast hurriedly came over to say hello, this Great Dragon Sword was able to step from the middle grade Dao weapon to the upper grade Dao weapon, and they were also excited from the bottom of their hearts.

With this high-grade Dao weapon Great Dragon Sword, it means that they already have enough strength to fight against Shen Yun Gongzi.

Even if Shen Yun Gongzi had a high-grade Dao Weapon Zixiao Dragon Bed, he didn't have to be as jealous of the other party as before!

Of course, this would not have been possible without them.

Qin Tian held the Great Dragon Knife in his hand and smiled slightly, he was about to speak, when at this moment, there was a sudden explosion outside, and the entire space of the Peak of Time and Space shook.

"What's going on?" the faces of the Soul Devouring Holy Beast and the other powerhouses changed.

Qin Tian raised his eyebrows, his spiritual power probed outside, and then his eyes narrowed slightly: "It's that Shen Yun Gongzi, he caught up, but fortunately, we have already condensed the Great Dragon Sword into a high-grade Dao weapon, fortunately, he didn't catch up at the most critical time!"

The outside of the Peak of Time and Space was shaken, and Qin Tian could clearly feel that a wave of mana outside enveloped the Peak of Time and Space.

This mana is very powerful, and there are also streams of spatial power infiltrating in, although it has not yet reached the point of changing the laws of space, but there is no doubt that it is the power of the high-grade Dao weapon.

Not surprisingly, it should be Shen Yun Gongzi who is using the high-grade Dao Weapon Zixiao Dragon Bed to attack the Peak of Time and Space.

"Haha, it's just in time, the big dragon knife just stepped into the high-grade Dao weapon, then, use him to try your hand!"

As he spoke, Qin Tian's body shook, and he immediately broke through the air and flew out of the top of time and space.

Coming out with him is the Soul Eater Holy Beast!

After coming out of the peak of time and space, Qin Tian saw that Shen Yun Gongzi was standing in a fog, and his high-grade Dao weapon, the Zixiao Dragon Bed, had been sacrificed, blocking the space!

"Who the hell are you, you actually dare to plunder the two deputy hall masters of my Nine Heavens Immortal Palace's Zixiao Palace!"

When Shen Yun Gongzi saw Qin Tian and the Soul Devouring Holy Beast come out, he unexpectedly didn't make a move, but instead calmed down, which made Qin Tian slightly stunned.

Because he thought that the other party would definitely be angry.
