However, this is what he thinks about too much. After all, the Netherfire Sea was too far away, and there was not much power that could be borrowed, so it was quickly and completely suppressed by the golden thunder.

Under the terrifying defensive power of the Ancient God Tower, the Void Passage was unstable and about to collapse, and the Nether Demon Venerable immediately entered this passage with Yin Qianyu and left the Ancient God Tower World.

With the departure of the Nether Demon Venerable, the Nether Fire Sea and the dark eyes quickly disappeared, and the sky returned to calm, as if nothing had happened.

"It turns out that they left the world of the Ancient God Tower in this way! I thought that the Demon Dao figure was coming, and it scared me to death. Li Qing breathed a sigh of relief.

The Nether Demon Venerable was sealed by the Ancient God Tower, and he couldn't leave the Ancient God Tower in a normal way, so he could only pay such a big price to escape from here by breaking through the Void Passage.

Just witnessed this wonderful scene, which made Li Qing feel a lot of emotion. This is the top power in the world, it can destroy the world, and he is too small in front of these terrifying powers.

That pair of huge demon eyes should be a Dao weapon, which was obviously used by the Ten Thousand Demon Sect to pick up the Netherworld Demon Venerable's departure. Li Qing recalled it in his mind, and soon remembered that in the Demon Dao, there was indeed a Demon Dao Supreme Treasure, called the "Demon God's Eye".

Speaking of this Demon God's Vision, its origin is also extremely amazing. Since ancient times, the Demon Dao has been suppressed by the Righteous Path, but it does not mean that the Demon Dao does not have the ability to fight back.

In history, there have been three large-scale wars of righteousness and demons, and the battles were very tragic and caused great damage.

Among them, the Second Righteous Demon War was led by a peerless demon known as the "Great Demon God". This war took place during the period of the Extreme Emperor, but unfortunately it was ultimately defeated at the hands of the Extreme Emperor.

This "Demon God's Eye" is refined from the eyes of this great Demon God.

Legend has it that this great demon god was born with heavy pupils, and a pair of eyes are extremely weird, and he can see through yin and yang, life and death, void, and creation, and has supreme power. It was with these magical eyes that the Demon Dao led by the Great Demon God was able to confront the Extreme Emperor.

At that time, the Extreme Emperor was not the Extreme Emperor, and it had only been long after he became enlightened, but his combat power was already extremely terrifying.

But there is a shortcoming of these two masters, that is, they only pursue the maximum power, go straight to the point, and lack some changes and subtleties.

And the Great Demon God relies on these eyes, which are incomparably subtle, and can often use ingenious means to deal with the Extreme Emperor.

However, as the Extreme Emperor continued to improve, his strength became stronger and stronger, and he broke through ten thousand laws with one force, and the Great Demon God was finally defeated in the hands of the Extreme Emperor, and the Second True Demon War came to an end.

It was by virtue of his amazing exploits in the Great War of Righteousness and Demons that the Extreme Emperor gained the prestige of the world, and his prestige reached its peak, and he later unified the Five Domains and became the second generation of human emperors in the Middle Ages.

After the death of the Great Demon God, his eyes were refined into the Eye of the Demon God, and the power was simply earth-shattering, with many mysterious and unparalleled effects.

"I didn't expect to use the Demon God's Vision in order to rescue the Netherworld Demon Venerable!What secrets are hidden in the Netherworld Demon Venerable?" Li Qing was puzzled.

The power of the Demon God's Vision is indeed extremely powerful, but every time it is used, it requires a huge amount of energy. It was obviously not an easy task to rescue the Nether Demon Venerable from the Ancient God Tower.

"Whatever, the Netherworld Demon Venerable and Yin Qianyu have left, and I am the only one left in this sixth layer world, and the world will be quiet now. Li Qing's face showed a hint of joy.

"To enter the seventh layer, you need a tenth-order demon king's inner dan! you have to go out to complete the task!" Li Qing couldn't help but look at the gate behind him, there were two beast mouths on the door, which were used to devour the inner dan.

Only by devouring the inner dan will the door open.

Li Qing didn't dare to break open this gate with brute force. According to rumors, there have been people who tried to break through the gate directly with treasures and tried to break into the ancient god hall, but the two beast mouths on the gate turned directly into two unicorn beasts and swallowed the person who broke in.

After all, this is the land of the ancient god clan, and Li Qing has the Heavenly Sword and is not sure that he will be able to break in, so he doesn't plan to take risks.

Although it is very difficult to kill the tenth-order demon king, if you use the heavenly sword to sneak attack, it is still a little possible.

If the sneak attack is not successful, it is a big deal that you will not go to the seventh layer, anyway, the sixth layer is not bad, it is not worth the risk.

Li Qing's current cultivation is only five levels of innate strength, and he is five realms away from the tenth-order demon king, and there is also a huge gap of the seven-fold innate among them, you can imagine how big the gap is.

The tenth-order demon king is ten times stronger than the ninth-order demon king, which is already the top and most complete level of the demon king realm. If it weren't for the Heavenly Sword in hand, even if ten Li Qing added up, it wouldn't be enough to fight.

Li Qing left the light mask. This mask is not in and out, and there is no obstacle to getting out.

He began to search for the Tenth-Order Demon King.

Although this is the sixth layer of the world, which is considered a very high-end world, the tenth-order demon kings are still not easy to see, and the number is extremely rare.

Li Qing searched for five days, and finally found a tenth-order demon king, and to his surprise, this demon beast was actually injured.

"Could it be that he was injured by the Nether Demon Venerable?" Li Qing couldn't help but think.

With the character of the Netherworld Demon Venerable, he must be on a rampage in this sixth-layer world, and there should be many powerful demon beasts that have been provoked. The tenth-order demon king is really too weak for the Netherworld Demon Venerable, that is, he can pinch it to death casually, maybe the demon beast of the demon saint level can enter his magic eye.

If that's the case, it's a little bit easier. I didn't expect the Nether Demon Venerable to do me a favor. Li Qing was overjoyed.

This demon beast is a green wood beast, it looks like a tree, and its temperament is relatively mild, and its strength is relatively weak among the demon beasts, which is suitable for killing.

Li Qing sneaked to the vicinity of the Bimu Beast, and there were countless things on its body that looked like branches, which were its arms, which were broken a lot at this time, only a few sparse ones.

It can be seen that there is a faint demonic qi on its body, which should be injured by the Netherworld Demon Venerable. The green light on the Bimu Beast's body flashed, and it was suppressing the Nether Demon Qi with all its might, and most of its power was contained.

What a godsend!

"Kill!"

Li Qing immediately rushed forward, and with lightning speed, he slashed out, the purple knife light lit up, and the body of the Bimu Beast was directly cut off.

However, it was not dead, only half of its body remained, its vitality was too strong, and several arms still whipped it, like lightning, and the speed was incredible.

Li Qing couldn't react, and if he was hit hard, he flew upside down in an instant, shattering a small mountain.

"Ahem!" Li Qing spat out a mouthful of blood, and the injury was not light.

Unexpectedly, after the Bimu Beast knocked Li Qing away, it did not take advantage of the victory to pursue, but turned around and fled.

"Where to escape!" Li Qing turned the Ten Thousand Demon True Body, recovered, and immediately followed.

Green blood was constantly flowing from the Wood Beast's body, and its injuries were getting worse and heavier, and its speed gradually slowed down.

What's more, the knife that Li Qing slashed out used the move of "slashing and killing", containing the power of extermination, the vitality of the Bimu Beast was slowly eroded, and the demonic energy of the Netherworld Demon Venerable was entangled, under the double damage, where could it still be supported?

In the end, Li Qing didn't make a move at all, and it fell.

A tenth-order demon beast was dealt with like this, which was also Li Qing's good luck.

He was hit by several arms of the Bimu Beast, and his injuries were very serious, after all, he was a tenth-order demon king, if it weren't for the injury of this demon beast, I am afraid that one blow would have beaten Li Qing half to death.

Li Qing suffered serious internal injuries and recuperated for an hour before he fully recovered.

He took out the inner pill and returned the same way, and soon came to the front of the light mask, and repeated his trick, wielding the heavenly sword to slash at the light mask.

It took him more than half a day to break through a small hole that he could get into, and then he got into it.

He threw the tenth-order demon king's inner dan into the beast's mouth on the gate, and the gate slowly opened. The ancient hall, which no one had entered for tens of thousands of years, finally appeared in front of Li Qing.

The situation inside is similar to the ancient god hall below, except that the patterns and runes on it are different.

Speaking of which, Li Qing can understand a lot of the patterns on it, but none of the runes know it. These runes look a little weird, a bit like the words of the ancient gods, but they are different.

Li Qing felt that these runes should be related to the formation. It's a pity that he can't find any information about this at all, maybe this is a secret of the ancient god clan, and it can't be leaked, so there is no record.

The patterns on this are different from those seen earlier, and the patterns recorded on the sixth layer are mainly about the exploits of the ancient gods themselves.

In the Ancient God Tower, each layer suppressed a peerless demon or a big demon, and these big demons and demons were all suppressed by the ancient gods after defeating them themselves, representing his supreme achievements.

It can be seen from the pattern on the wall that the monster on the second layer is indeed the demon ancestor tree. The most tragic is the sixth layer, the ancient god used a trick to lure the Nether Demon Venerable out of the Nether Fire Sea, set a trap, and after a fierce battle, it was successfully suppressed.

In addition, there is also the origin of this ancient god tower, each layer of the ancient god tower is a small world, magnificent and magnificent. But according to the pattern above, Li Qing learned that these seven small worlds are actually connected, and they are essentially all in the same world, but they are separated by the Ancient God Tower.

Because of the strength of the ancient gods, the world he opened up is so big. And if there are descendants who can reach his level, they can also expand the world of the Ancient God Tower.

The ancient gods spent most of their lives building the Ancient God Tower, and it took countless efforts, which is a place that is ready to be used as a foundation for the survival of the ancient gods, and it will be passed on forever.

Originally, the Ancient God Tower was not called the Ancient God Tower, but the "Tower of Eternity".

It's just that the hard work of the ancient gods was in vain, and no matter how powerful the treasure was, it couldn't withstand the passage of time, and the ancient gods finally perished.

After reading these patterns, Li Qing entered the light gate and came to the seventh layer of the world.
