When Li Yi was desperately refining the Seventh Realm King, Time Tianzun and Five Elements Tianzun were groping in the tombs of the Four Emperors.

It was pitch black all around, and the Vermilion Bird Tianzun released a flame to illuminate the surrounding range of hundreds of zhang, only to see that on both sides were towering stone walls, on which many murals were carved, which had long been mottled.

The mural records the deeds of the Four Emperors of the Ancient Dynasty during their lifetimes, including how to fight the Seventh Human Realm and how to fight the Demon Clan in the Necromantic Sea. However, the Five Elements Heavenly Venerable searched and searched, but he did not find a clue to the Ninth Human Realm.

On the other hand, Time Tianzun had no interest in the murals, he was extremely fast, and it didn't take long for him to leave the Five Elements Tianzun behind, and he was alone, exploring everywhere.

He was looking for the King of the Seventh Realm.

Back then, the Four Emperors hit the Seventh Human Realm, and the whereabouts of the Seventh Realm King were unknown, many people thought that the Seventh Realm King was dead, but Time Tianzun believed that the Seventh Realm King was not dead, because the Seventh Realm King was almost immortal, and it was impossible to kill him.

Time Tianzun had searched all over the Necromantic Sea, but he had not found the whereabouts of the Seventh Realm King, and later found the tomb of the Four Emperors in the northern part of Changsheng Island, so he guessed that the Seventh Realm King might have been suppressed here.

This tomb of the Four Emperors is actually a small world opened up by the Thunder Emperor and the Fire Emperor before he died, and the passages inside are extremely complicated, like a labyrinth, and in some places, there are even formations, if you accidentally step into it, if you want to break out of the formation, you have to spend a lot of energy.

Time Tianzun was like a fly without a head, and he searched for several days in a row, but he still didn't find the Seventh Realm King, but for some reason, the premonition in his heart became stronger and stronger, the Seventh Realm King must be somewhere in the tomb of the Four Emperors.

"Those Terrans don't know where to hide. Time Tianzun couldn't find the king of the seventh realm, he was already in a bad mood, and he was even more annoyed when he thought of being escaped by Li Yi and others, "Let me bump into it, I have to let you die miserably under my hands!"

For Time Tianzun, Li Yi and the others still have a very important value, which is to let the Seventh Realm King refine and restore his strength. After all, the King of the Seventh Realm has been suppressed for many years, and his strength must have declined greatly, and he needs to refine the human race to recover his strength.

But what Time Tianzun couldn't have imagined was that the Seventh Realm King was being refined by Li Yi at this moment.

Li Yi's body refining demon recipe was running wildly, desperately devouring the seventh realm king's natal essence blood, when the last drop of natal essence blood was also devoured by Li Yi, the seventh realm king's throat made a strange sound, his eyes were full of unwillingness, the hand that grabbed Li Yi's throat loosened, and his body gradually turned into ashes and disappeared.

If the king of the seventh realm had one-tenth of his strength at his peak, Li Yi would not have been able to kill him, but after the king of the seventh realm was defeated by the four emperors of the ancients, he suppressed it for so many years, and his strength was less than one-tenth, plus Li Yi's demon refining technique was the nemesis of the demon clan, which made the king of the seventh realm killed by Li Yi.

Li Yi devoured the natal essence blood of the Seventh Realm King, and his lower abdomen bulged high. That mass of natal essence blood was raging wildly in his body, as if he wanted to rebel against the guest.

The king of the seventh realm is worthy of being the power of the demon clan, and there is still a trace of divine soul will left in the natal essence blood, and under the continuous impact, Li Yi has suffered a lot.

Li Yi frowned, felt a sharp pain coming, and hurriedly gritted his teeth, urging the Law of Gold to protect his body, which relieved the pain slightly, and then he urged the Law of Thunder to release thunder one after another, bombarding the ball of natal essence blood, wanting to scatter it.

Who knew that the mass of natal essence blood was extremely condensed, like a gelatin, and it couldn't be dispersed no matter how it bombarded.

So Li Yi picked up his fist and kept beating himself.

As soon as the punch went down, there was a sound of bells, and the force penetrated through a thousand pounds, which shocked Li Yi faintly in pain.

The natal essence blood of the king of the seventh realm seemed to sense Li Yi's intentions, and suddenly condensed into a blood sword, rushing to kill everywhere. Even though Li Yi had the law of gold to protect his body, it was still difficult to resist, and in a moment, his body was already scarred, and all his internal organs were stabbed by the blood sword.

"If it goes on like this, I will have to be stabbed to death by it!" Li Yi felt a strong sense of crisis.

He urged the Law of Gold even more desperately, almost all the strength of his body had been used, and his fists came out together, shaking his flesh and clanging, but he still couldn't stop the blood sword.

Feeling that there was nothing to be done, suddenly, Li Yi's heart moved, and he took out the Sun and Moon Twin Swords and the Immortal Exterminating Sword from the storage bag.

The Immortal Exterminating Sword is a half-grade immortal weapon, and since Li Yi got this sword, he has been trying every means to refine it, but unfortunately it was in vain, so he could only use the Sun and Moon Twin Swords to temporarily imprison it.

At this time, his life hung by a thread, Li Yi couldn't think much about it, turned his heart sideways, put away the sun and moon double swords, urged the devouring law, and swallowed the immortal extermination sword into his body.

The Immortal Exterminating Sword has extremely high spirituality, and after breaking away from the confinement of the Sun and Moon Twin Swords, he immediately has a sword aura, wanting to break out of the encirclement and break through the shackles of Li Yi's body.

At this moment, the bloody sword rushed over.

The Immortal Exterminating Sword once suffered a little loss in the hands of the Ninth Realm King, and he didn't have a good impression of the demon clan's breath, so he fought with the Blood Sword and killed it in the dark.

Although the sword qi that erupted made Li Yi a little painful, with the law of gold to protect his body, after all, there was no worry about his life. At the same time, in the battle with the Immortal Exterminating Sword, the blood qi inside the Blood Sword began to be shaken out little by little.

Li Yi hurriedly urged the demon refining technique, inhaled a trace of blood qi into the meridians, and then ran it every day, and after one hundred and eight days of heaven, it was finally refined.

Suddenly, a majestic true qi poured into Li Yi's realm, causing his realm to expand by hundreds of zhang in an instant. There was also a part of the blood qi integrated into Li Yi's body, which not only allowed him to recover from all his injuries, but also greatly enhanced his physical strength.

It was just refining a trace of blood qi, but the benefits it brought to Li Yi were worth several years of ordinary cultivation.

This made Li Yi secretly happy, while continuing to refine.

After refining a few traces of blood qi in a row, Li Yi's realm suddenly shook, and a huge transformation occurred, reaching five thousand zhang, and the strength of his whole body skyrocketed.

Field Sevenfold!

Li Yi's realm had just broken through the sixth level of the realm not long ago, and he thought that it would take a long time to continue to break through, but he didn't expect to break through the shackles in one fell swoop at this time and step into the seventh realm of the realm.

And that blood sword has only been refined by less than a tenth.

Li Yi was ecstatic.

If he could refine all of that blood sword, he didn't know how far his cultivation would improve.

Li Yi was very curious in his heart, and he refined it even more vigorously.

In another cave in the Tomb of the Four Emperors, Bi Ying and Lin Wei saw an old man in a purple robe.

The purple-robed old man was the remnant soul of the Thunder Emperor.

The remnant soul of the Thunder Emperor originally wanted to teach the Thunder Emperor Recipe to the two, but found that the two had already learned it, and couldn't help but be a little surprised.

"Okay, okay, there is someone to succeed my Shenxiao Sect!" "The remnant soul of the Thunder Emperor was very pleased, "I can also be blind when I die!"

Lin Wei asked, "Master Zu, do you have any powerful magic weapons here, can you give us one?"

The remnant soul of the Thunder Emperor said: "I don't have a magic weapon, but since you have found here, I can't let you go home empty-handed. Well, I'll take you somewhere. ”

Lin Wei and Bi Ying looked at each other and followed behind the remnant soul of the Thunder Emperor.

After leaving the cave, I walked in the passage for a long time when I suddenly heard thunder in my ears.

Biying felt strange, and then walked into a cave, only to see that in the center of the cave, there was a spring, but the spring water was different from ordinary water, showing a purple and blue color, and there was a faint thunder flickering in it, making a rumbling sound.

The remnant soul of the Thunder Emperor said: "This spiritual spring is the Earth Yin Thunder Spring, which is formed by the underground Yin Thunder for hundreds of thousands of years, when I found this Earth Yin Thunder Spring, I originally planned to refine it myself, but unfortunately it is too strong and incompatible with me, and it is not suitable for men to refine." You two will refine it!"

Bi Ying and Lin Wei plucked up their courage and jumped into the Earth Yin Thunder Spring, and immediately felt the pain of a thousand thunder bombardments, and at the same time, they were cold to the bone, as if they had entered an underground abyss.

"Protect your heart and urge the Thunder Emperor's Secret Method!" said the Thunder Emperor's remnant soul, "I'm here to help you!"

As he spoke, he also jumped into the Earth Yin Thunder Spring, and put his hands behind Biying and Lin Wei.

Bi Ying and the others only felt a heat coming from behind them, and their souls suddenly shook, and they hurriedly used their true qi to protect their hearts, urging the Thunder Emperor Jue, and began to absorb the power of the Earth Yin Thunder Spring.

A trace of spring water seeped into the bodies of the two of them, and after Zhou Tian's operation, it turned into an incomparably thick true qi.

"Okay, okay, there is someone to succeed my Shenxiao Sect!" "The remnant soul of the Thunder Emperor was very pleased, "I can also be blind when I die!"

Lin Wei asked, "Master Zu, do you have any powerful magic weapons here, can you give us one?"

The remnant soul of the Thunder Emperor said: "I don't have a magic weapon, but since you have found here, I can't let you go home empty-handed. Well, I'll take you somewhere. ”

Lin Wei and Bi Ying looked at each other and followed behind the remnant soul of the Thunder Emperor.

As he spoke, he also jumped into the Earth Yin Thunder Spring, and put his hands behind Biying and Lin Wei.
