The huge crack was like a giant mouth, leaving no room for the two of them to resist at all.

A terrifying light engulfed them in that instant.

Yu Han grabbed it with his backhand and grabbed the soft that Nangong Jinxuan also caught.

Under the current situation, there is no longer half a point of charm, and the two of them have only stabilized after they have used their true qi.

The speed of the fall also decreased, and the two figures began to slowly move sideways to one side.

Whew-

At this moment, they seemed to have fallen into a spatial rift, and there was a breath of spatial shattering everywhere.

It was pitch black everywhere, and it was visible to the naked eye that there were scattered air currents on both sides, hitting their body protection true qi, causing their body protection true qi to vibrate violently, as if it might collapse at any time.

I don't know how long it took, but the surrounding atmosphere finally became quiet.

The figures of the two were finally controlled, no longer affected by that force, and were suspended there under the deliberate urging.

Yu Han's eyes narrowed slightly, and the space around him was bright, it seemed to be a palace deep underground, and the traces of its ruins were very obvious, along with those huge stones, which were covered with cracks.

What's even more obvious is that those traces of the remaining fights, I don't know how many years have passed, there are still terrifying sword qi and divine powers faintly flowing, making them in danger anytime and anywhere.

"It's ...... here," Nangong Jinxuan Dai frowned slightly.

Yu Han naturally let go of the hand holding her, turned his head and asked, "Do you have an impression?"

Nangong Jinxuan shook her head: "There has never been a legend about this palace, you look at the area around here, it looks like it is no worse than the human palace, it must have been a palace that I thought was a powerful person!"

"And on the remaining stones around here, there are also traces of formation, plus the sword marks that were cut out on it, the battle of the year was absolutely earth-shattering, crying ghosts and gods!"

Yu Han sighed and said: "That's true, those wooden pillars have not rotted after a long time, which shows the grandeur of this palace, I'm afraid it's not even as good as the human palace!"

"Could it be a prehistoric civilization?" Nangong Jinxuan suddenly spoke.

Prehistoric civilization? Yu Han heard this word for the first time, and his face immediately became extremely difficult to see.

Unlike Nangong Jinxuan, his knowledge of this world is still too little, although the little guy has found a lot of classics for him, but compared to Nangong Jinxuan, who was born in a big family, it is still too bad.

Now when I heard about the prehistoric civilization, I couldn't help but show some doubts.

Nangong Jinxuan said: "Prehistoric civilization is actually an era of mutual handover with the primeval era, and the reason why it is so called is because in that era, the cultivation of human beings has reached its peak!"

"They dominate this world, even the demon clan can only be reduced to vassals, all the powerful and powerful people are from the human race, and it is said that those strong people can tear the void between their gestures!"

"They control the Heavenly Dao, they have surpassed the strength of cultivators, and they are an existence similar to gods!"

"What happened later?" Yu Han frowned, which seemed to give him a new understanding of his previous speculation.

Nangong Jinxuan continued: "Later, the strength of the human race was feared by the Great Dao of Heaven and Earth in this world, maybe he was afraid that one day, these people would change their lives against the sky and achieve the Great Dao, so as to get rid of his shackles!"

"So, he launched the Great Tribulation!"

Yu Han's eyes flickered, this should have been a long time ago, and it seemed to be beyond the primeval era.

Nangong Jinxuan said: "That catastrophe, almost no memory has been passed down, but after research, the surviving people guessed that this is definitely a great catastrophe for the human race!"

"What's even more bizarre is that those top powerhouses of the human race have disappeared and there is no trace, thus giving the demon race time to grow, and that is, after the World Destruction Tribulation, there is a new race in this world - the Immortal Race!"

What Nangong Jinxuan said seemed to be a secret, and when she mentioned the immortal clan, Yu Han's eyebrows jumped again.

I have long heard that the immortal clan was originally from the human race, and now it seems that there is nothing wrong with it.

The power of those prehistoric civilizations already possessed such terrifying power, and it was absolutely impossible to disappear out of thin air.

No matter how powerful the avenue of this world is, it always needs the support of these strong people.

Therefore, he will not destroy these strong people for no reason, and can only contain them.

After thinking about it, Nangong Jinxuan continued: "This matter has passed for a long time, and it is said that only the immortal clan knows some inside stories, because they are a race that appeared out of thin air, and it is likely to have something to do with this world-destroying catastrophe, as for the demon race and the human race, they are both reborn in the destruction of the world, and there is only a blank in history!"

"And the immortal clan seems to have come with a mission, they are like the current extraterritorial demons, they have always been ambitious, when they first appeared, because the power of the human race has fallen, so the human race is losing and retreating!"

"A large number of vast areas were occupied by the Immortal Race, and it was the first generation of the Human Emperor who appeared later and led the Terran masters to fight back desperately, so that this three-legged situation was laid!"

"The demon clan is on the safe side and has a long life, so we don't have many scruples, but compared to others, these things are absolutely immeasurable!"

Speaking of this, Nangong Jinxuan didn't continue, but looked around: "This place is so splendid, its scale is far older than any contemporary palace, it is likely to be the prehistoric civilization of the past!"

Yu Han stretched out his foot and picked up a spear that was stuck upside down next to his right foot.

The spear went limp and turned into a cloud of dust.

"It's a pity, this place is already in ruins, you see that these great artifacts of the year have also been buried with time, lost all their spirituality, and turned into dust!" Yu Han said slightly.

"Otherwise, if we find the opportunity here, I'm afraid that the cultivation of the two of us will have a huge improvement!"

Nangong Jinxuan also nodded: "The inheritance left by those powerful predecessors of the prehistoric civilization back then is of course extraordinary!"

Yu Han said slightly: "Since we are here, let's take a look around first, since that senior let us down like this, I think there must be a reason for him!"

The two landed on the ground and walked towards the front.

The ruins were close to destruction, and even the light around them had dimmed.

There is no place where there is still a trace of the avenue.

Yu Han and Nangong Jinxuan walked side by side, not fast, walking through this ruin, and at the same time stretched out the true qi of the protective body, resisting the scattered air currents that were constantly sweeping around.

"There's a stone tablet over there!" Nangong Jinxuan's eyes lit up.

It was a ruined stone tablet, with blurred handwriting and strange writing, so different from the current text that it was impossible to read even if you made it easier to read the contents.

But in the midst of this ruin, this stele is unusually abrupt.

Because it's the only thing here that hasn't been destroyed, it's still intact.

Except for a few thick cracks on it, which were left by a sword or sword qi slash, it was not weathered like other stones that fell to the ground.

Yu Han's eyes narrowed slightly, and his face became solemn little by little.

Because at this moment, his left hand was on fire, and the Ten Thousand Tribulation Thunder Method in his body suddenly ran automatically uncontrollably.

Not only that, but the right hand is hot and cold alternately, and the reincarnation grinding disc rotates automatically.

These two avenues, as if they had been stimulated by something, had escaped from his control.

In a hurry, he turned his head to look at Nangong Jinxuan beside him, and was shocked to find that Nangong Jinxuan's situation seemed to be inferior to his own, and her pretty face was already drunk red.

The clothes on his body turned to ashes in an instant, and in his place were a scorching flame.

Nangong Jinxuan seemed to have lost consciousness, wrapped in a terrifying firelight, and her endless power turned over and over.

"What the hell is this?" Yu Han was shocked.

He felt as if a force was about to enter his consciousness.

However, the sword furnace in the sea space spun rapidly, and those primeval sword intents roared out, automatically repelling this power.

Not only that, but along with the Heijo sword behind him, he was also a little uneasy, beating violently behind his back.

"What's going on?"

He had just had this question, and suddenly a blurred light and shadow appeared in front of him.

"Heavenly thunder in the left hand, reincarnation in the right hand!"

It was a voice that had reached the point of vicissitudes, and it was impossible to say such a thing unless someone with great energy could say it.

His words almost fell, and Yu Han felt a sudden sharp pain in his left hand.

He subconsciously stretched out his left hand.

Silver-white textures emerge, and finally condense in the palm of the hand, turning into a mysterious symbol.

With a slight grip of his left hand, there was a crackling spark.

The pain finally disappeared.

However, immediately afterward, there was a sharp pain in the right hand, and like the symbol of the left hand, a gray-white roulette wheel formed in the palm of the right hand.

At this moment, Yu Han was shaken violently.

He finally understood the meaning of the voice before, the thunder in his left hand, and the reincarnation of his right hand, isn't it his own at this moment?

Thinking of this, he suddenly raised his head and looked at the light and shadow in front of him.

"I didn't expect it to be fused so quickly!"

"Heaven is unkind, and all things are used as dogs!"

The voice seemed to be talking to itself, and it seemed to sigh, but at this moment, there was a bit of joy in the voice.

Then he continued before Yu Han could react.

"The foundation of the human race is with life, life is endless, and the human race is immortal!"

"All you can destroy is the rules!"

"But even if the rules are changed, the Terrans will still not be destroyed!"

"It seems that my resistance is meaningful, what I haven't done, someone will be able to do it!"

"It's just a pity that I can't see it!"

"Dust to dust, dust to dust, a lifetime of rebelliousness, to the present...... I can finally give up!"

The voice gradually dissipated, and Yu Han finally resumed his movements at this moment.
