Dao Heavenly Sect, in the seven underground floors of the Star Power Cultivation Tower Fire Tower, a figure was naked, and his arms wrapped in green scales carried bursts of blue thunder and star power every time he waved.

The dragon claw clenched hard, and the last Fire Spirit Star Beast in front of him couldn't withstand the powerful claw force, and it exploded in an instant.

The rich and pure fire attribute star power turned into a surging streamer, surging and undulating like a tide, merging into Yi Xiaotian's Heavenly Spirit Cave.

"Nine thousand nine hundred and ninety-nine, it's time to impact the Bone Refining Realm!"

No longer suppressing the surging star power in his body, Yi Xiaotian took out a star core, a sixth-order top-grade star core, and a purgatory dark ancient dragon star core.

The purgatory dark ancient dragon of this supreme star core's body was once the overlord of the Star Spirit Mountain Range, and it was a disaster for everyone during his lifetime.

Ten years ago, a genius disciple of Dao Tianzong was at the peak of the ninefold peak of the Divine Waiting Realm, and wanted to break through the Divine General Realm, when he heard that there was a fire-based evil dragon in the south of the Star Spirit Mountain Range, so he joined forces with friends from the three or five sects to go to the south of the Star Spirit Mountain Range, wanting to kill the evil dragon and take the star core.

As soon as a few disciples stepped into the territory of the evil dragon, they were attacked by it, and several disciples of the Dao Heaven Sect were all Tianjiao figures at that time, and their combat power was not bad, but several of them were still invincible to the evil dragon.

Not only that, when several Divine Waiting Realm disciples found out that they were invincible, they also sent a distress signal to the sect, and it was a Divine General Realm Triple Deacon Elder who came to the rescue at that time.

The Purgatory Dark Ancient Dragon was at the peak of the sixth order at that time, and although the Divine General Triple Martial Artist against a sixth-order star beast could not be said to be easily defeated, it was still possible to save a few Divine Waiting Realm disciples, however, the Deacon Elder of the Dao Heaven Sect and several Divine Waiting Realm disciples greatly underestimated the strength of this Dragon Blood Star Beast.

One god general, five god marquis, all died under its claws.

In the end, it was the head Lin Potian who used the Dao Heavenly Xuanjing to kill him.

A sixth-order peak star beast is equivalent to a ninefold peak martial artist of the Terran God Waiting Realm, but it can kill a deacon elder of the Divine Commander Realm.

When Yi Xiaotian saw this star core in the Yingwu Palace, its price was 90,000 sect merits.

Ordinary sixth-order top-grade star cores are only sold for 50,000 sect merits, and a seventh-order low-grade star core is only sold for 100,000 sect merits, and the price of this sixth-order top-grade star core is almost the same as that of a seventh-order star core.

The pricing of the items in the Heroic Martial Hall was not arbitrarily set, and the price of this Purgatory Ancient Dragon Star Core was set by the head of the house himself, because this star beast was killed by him, according to what he said at the time, this sixth-order star beast was close to transforming into a hegemon-level star beast, and it was only one step away from being able to cross the tribulation and be promoted, and its combat power was already enough to be comparable to some ordinary seventh-order early-stage star beasts at that time, and it could no longer be regarded as a sixth-order star beast.

Yi Xiaotian had also seen a sixth-order peak star beast, the Netherworld White Tiger King, the sixth-order peak, the ontology purgatory dark ancient dragon of the star core in his hand might be even more powerful than that Netherworld White Tiger King during his lifetime, because that Netherworld White Tiger King had no sign of transforming into a hegemon-level star beast at all.

"The sixth-order top-grade star core that only breaks through the Divine General Realm, and the sixth star core of an ordinary Tianjiao disciple can use the martial arts of the sixth-order best, and I have just broken through the Bone Refining Realm, and my fourth star core, with such a powerful star core, can it withstand the impact of the star power contained in it?"

"I don't know if this breakthrough, the Qinglong Nine Transformation can be cultivated to the fourth level, but it doesn't matter, if I can awaken my martial soul into a purgatory dark ancient dragon, it will definitely be stronger than the Red Flame Horned Dragon." Yi Xiaotian muttered to himself, full of hope for this star core, and knew that it was full of great unknowns and risks.

Although the Red Flame Horned Dragon is a sixth-grade martial soul true body, it is the weakest one among the six grades, and it is one line stronger than the previous fifth-grade martial soul lava dragon, and it is always slightly insufficient compared to other sixth-grade martial soul true bodies.

If after absorbing this star core, he can evolve his Red Flame Horned Dragon into the true body of the Dark Ancient Dragon Martial Soul of Purgatory, then he can fight with the vast majority of the seventh-grade Tianjiao just by relying on the power of the true body of the martial soul, just like the two brothers Yu Can, they have the true body of the sixth-grade martial soul, which is comparable to the genius of the ordinary seventh-grade martial soul, plus other martial arts and combat experience, the two brothers have always been not weaker than the disciples of the seventh-grade martial soul.

However, now that the two Yu Can brothers have been inherited by Emperor Li Po, their martial spirits may also undergo transformation.

Of course, that's all for later.

If his martial soul true body can evolve into a purgatory dark dragon, his combat power will be greatly improved.

If you want to catch up with those Tianjiao who have a seventh-grade martial soul true body and an eighth-grade martial soul true body, you must take risks.

"My first star core is a fourth-order star core, and the third star core has surpassed ordinary people, this time, I can do the same!" Yi Xiaotian no longer hesitated, the breakthrough was imminent, and he immediately operated the Qinglong Nine Transformation Technique, and the surging star power in his body broke through the invisible barrier in his body in an instant.

"Bone Refining Realm, I'm Yi Xiaotian here!"

In the seventh layer of the Fire Tower, all the fire star power instantly poured into Yi Xiaotian's body, and he did not hurry to refine these star powers, melt them into his body, and then guide them into the star core of the Purgatory Dark Ancient Dragon.

"The young sect master has been in the fire tower for half a year, could it be that he has encountered some trouble?" Because Dao Wuji had confessed that the seventh floor of the Fire Tower was banned, Huo Lao didn't know what the situation was inside the seventh layer of the Fire Tower, if it weren't for the formation of the Fire Tower showing that Yi Xiaotian was still alive, he would have to break in.

"I don't know if the young sect master can break through by killing six thousand six hundred fire spirit star beasts like the previous generation of sect masters." Huo Lao thought that after Yi Xiaotian got out of the customs, he must go to the fire tower to see how many Fire Spirit Star Beasts Yi Xiaotian could kill.

Just when Huo Lao sighed, Dao Tianzong once again issued an emergency announcement from the sect.

In the endless abyss, the Terran territory sealed the Demon Ridge and lost, the Terran sect was defeated, and the Demon army went to the next city.

Now that the demon army is advancing on all fronts in the endless abyss, the frontline cities guarded by the human clan sect have been routed on all fronts.

Lin Potian summoned all the disciples above the Dao Heaven Sect's Bone Refining Realm, including many disciples of the Divine Waiting Realm who had been trained outside to return to the sect, and the ten platinum disciples had already been sent to the Endless Abyss, all of which were the reserve combat power of the Dao Heaven Sect, there was no way, the Endless Abyss was in an emergency on all fronts, and the war was urgent.

Dao Wuji and Dao Heaven Sect, as the leaders and sects of the One Hundred and Eight Sects of the Star Spirit Empire, had already led the seven Supreme Elders to the Endless Abyss to guard it.

As a last resort, Dao Tianzong didn't want to send these disciples to the Endless Abyss, because they knew that in the Endless Abyss, Demon Guards, Demon Spirits, Demon Generals, Demon Kings, and even Demon Emperors all existed, and the Bone Refining Realm entered it, which played a very small role, but the demon army was hundreds of millions, countless, and if they didn't do their best, who would do their best?
