"Yes, the Di Tian Sword Spirit has refined my blood essence!"

Not long after Ye Zichen dripped his blood essence, he noticed that the heavily injured sword spirit had forcefully refined his blood essence, not giving him the chance to recognize it as master.

"I want to see how much of my blood essence you can refine."

"I've recovered. Di Tian Jian has finally recovered his middle grade Dao Artifact."

Ye Zichen revealed a smile as he felt the improvement in Di Tianyang's quality. Although he was unable to unleash Di Tianyi's strongest attack power with his current strength, he was able to kill a level two Battle-Beast Emperor with the sword spirit's amplitude and Di Tianyi's strength.

"Sword spirit, come out quickly. I have something to ask you."

The sword spirit had suppressed the fourth hall for more than a hundred thousand years, and knew a lot of secrets from the past. Ye Zichen put the four swords that were filled with killing intent into the Heaven and Earth Mirror and summoned the extremely weak sword spirit.

"Master, what do you want to ask me?"

The sword spirit asked indifferently as it floated out of Di Tian Sword, unable to resist Ye Zichen's thought after binding it with blood.

"Tell me, who is this' demon '? And who was it that suppressed him here? " Ye Chenfeng asked the secret of Dragon Lake in a low voice.

"You and that 'demon' aren't from the same group?" The sword spirit asked curiously.

"I'm not in the same group as him, but the suppression demon body I released really did have the power to exterminate him." Ye Chenfeng shook his head and said.

Alright, I will tell you the identity of that 'Demon'. That 'Demon' comes from the Heavenly Realm and claims to be the 'Cold Night Demon Saint', with the strength of a three star Dao Saint. Back then, his lower realm created a bloody storm on the Soul Dueling Continent, destroying many Sacred Grounds and killing a large number of geniuses.

"In the end, his bloody atrocities infuriated the old master and he fought him to the death. But the Cold Night Demon Saint is too terrifying. Even with master's strength back then, he was unable to kill the monster, so I had no choice but to sacrifice the contracted beast, the Azure Dragon. Using the body of the Azure Dragon, I refined the Heavenly Emperor Sword for a lifetime, severely injuring the Demon God of Cold Night, and suppressed his body and his contract beast, the Dark Black Mantis, in this land of life and death …

The sword spirit told Ye Zichen all of his secrets regarding the 'demon' without holding back.

"A 3-star Dao Saint!"

Ye Zichen knew that Dao Saints were in the Heavenly Realm. Although Dao Saints were not strong in the Heavenly Realm, they were able to dominate the low-tier Soul Dueling Continent.

"Sword spirit, how strong was your master back then?" Ye Zichen asked in a low voice, he really wanted to know Di Tian's strength.

"The old master, Di Tian, was once the Divine Emperor of the Nine Heavens Divine Kingdom. He was one of the most powerful pillars and was at the Nirvana Realm. It's been more than a hundred thousand years. I wonder if the old master has recovered from his injuries. The sword spirit said with a sigh.

"Nirvana Realm? "What realm is this?"

After fusing with the mind devouring, although Ye Zichen had a lot of inherited memories, it was his first time hearing about the Nirvana Realm.

"The Nirvana Realm is not the true cultivation realm. It is the failed ascension of a sixth level Battle-King. After his fleshly body was destroyed by the Heaven Gate, he had expended a lot of resources and borrowed the power of Heaven's Punishment to rebuild his cultivation realm."

"The Nirvana stage is divided into the Nirvana stage, Nirvana stage and Nirvana stage. It corresponds to a one star Dao Saint in the Heaven Domain, a two star Dao Saint and a three star Dao Saint."

"However, it is extremely difficult to reach the Nirvana stage. Not only do you need to collect a large number of rare treasures, you will also need a thousand years to transform, complete the Nirvana stage, rebuild your physical body and train to the Nirvana stage."

"Nirvana stage experts will be baptized by Nirvana heavenly punishment every thousand years. Only by surviving will they be able to extend their lives. However, in history, there have been too many almighty beings that have been annihilated by the Nirvana heavenly punishment."

"Moreover, it is extremely difficult for a Nirvana stage practitioner to tear open the gates to the Heavenly Realm again. In history, there are only a few supreme elders who have advanced to the Heavenly Realm through the Nirvana stage."

"However, once a Nirvana stage Supreme Elder ascends to the Heavenly Realm, his strength will far surpass that of ordinary Ascendants. He'll immediately break through to a 4-star Dao Saint." The sword spirit explained in detail.

"There is such a realm in the Soul Dueling Continent. It seems that my understanding of the entire Soul Dueling Continent is still too little."

Ye Zichen muttered to himself. He did not think that a level 6 beast emperor was not invincible in the Soul Dueling Continent. The true hegemon of the Soul Dueling Continent was a Nirvana Realm expert.

"Master, even the strength at the Nirvana Realm back then was unable to kill Demon Saint Ye and could only suppress him. Are you sure you can destroy him? Once he completely escapes, it will set off a bloody storm in the Soul Dueling Continent. Master, you will become a sinner for all eternity. " The sword spirit reminded him in a serious tone.

"Sword spirit, the one suppressed by the fourth hall should be the demon skull, right?" Ye Chenfeng pondered for a moment, then asked, "I wonder what treasure Senior Di Tian used to suppress the demon skull, did you have any Heavenly Crystals?"

In order to suppress them, Master moved in a Dragon Blood Tree, a Soul Suppressing Golden Tablet, and with the Azure Dragon Heart, eighteen middle-grade Heavenly Crystals, thirty-six low-grade Heavenly Crystals and set up a grand sealing formation. " The sword spirit said without hiding anything.

"Eighteen middle-ranked Heavenly Crystals and thirty-six low-ranked Heavenly Crystals."

When the Sword Spirit Puppet fused with these Heavenly Crystals, its strength would definitely surpass the Battle Beast Emperor and reach the Heavenly Domain Dao Saint level. It would have a complete chance of destroying the demon skull and his Dao soul, then the Demon Body would no longer be a threat.

Even if an accident happened at the last moment and the demonic skull and Dao Spirit escaped, losing their demonic hearts, the Cold Night Demon Saint, who had been suppressed for more than a hundred thousand years, would not be able to recover to his peak realm and the Sword Spirit Puppet would still have the chance to kill him.

More importantly, Ye Zichen was filled with interest towards the Dragon Blood Tree and Dragon's Heart that could suppress the demonic skull and Dao Spirit. If he was able to obtain these two great treasures, his strength would greatly increase, especially that of the Dragon's Heart.

"Sword spirit, seal the front hall, and then we'll go kill the demon skull and his Dao spirit." Ye Chenfeng took a deep breath and ordered.

"Master, you've really made up your mind!" The sword spirit asked.

"Yes."

Ye Chenfeng nodded heavily, then said with a firm tone.

"Sigh, alright then. Let's fight with our lives on the line."

The sword spirit was unable to resist Ye Chenfeng's thoughts, so it could only obediently obey his orders and activate the hidden restrictions in the shrine. It forcefully sealed the hall, then carried Ye Chenfeng through the restrictions and headed towards the depths of the hall, the hall where the demonic skull and the Dao Spirit were suppressed.
