Li Chenggong stood in the valley, his face full of anticipation, and his fiery gaze slowly swept over all the Nagu Towers.

Yes, these towers are the real Nagu Tower, which actually means tomb.

Once any of the Origin Demon Gate masters had a premonition that they would not be able to survive the next Heaven and Earth Tribulation, they would enter such a tower, and no one would ever come out again.

And before they entered, they also ordered that they could not knock on the door unless the First Demon Gate was to be destroyed.

However, the First Demon Sect is a super powerful sect of Chaos, and for hundreds of trillions of years, even if it has encountered many crises, it has survived unscathed, and none of them have fallen to the point of destroying the sect. Therefore, the doorman of the First Demon Gate has never come to knock on the door.

However, this time, the First Demon Gate was crippled by the Yanhuang Gate led by Zhang Dong and Liu Chao, and most of the giants and masters were imprisoned.

So, today, Li Chenggong is going to knock on the door.

And this is the essence of a tenth-level sect like the First Demon Gate, as long as a giant is still alive, it must be a terrifyingly powerful existence, and it will be easy to keep the First Demon Gate.

"Which tower do you start to?"

Li Chenggong muttered in his heart, and his gaze slowly moved to the row of bone towers at the front, which were all bone towers millions of years ago.

If there is an ancestor alive, it must be a super powerful giant.

Killing the Yanhuangmen is also assured.

"Let's start with the Nagu Tower, which is more than a trillion years old."

Li Chenggong muttered in his mouth, walked over slowly, came to a billion-year-old Nagu Tower, took a deep breath, and knocked softly on the door.

"Knock Knock Knock ......"

The sound is very crisp.

It's a pity that he knocked for a long time, but there was no movement.

He pushed the door hard, and it opened, and his divine sense instantly spread inside.

Inside was a vast world, planted with countless heaven and earth divine medicines.

However, it was desolate, there was no human figure, not even a bone could be seen.

"Alas...... This ancestor has fallen, this is the 508th generation master of the First Demon Gate, Helian has destroyed the sky, and he has been in chaos for more than 20 trillion years, and he has never encountered an opponent. However, he still fell. ”

Li Tiangao sighed in his heart and gently closed the door.

He came to another Nagu Tower, a 110 trillion year old Nagu Tower.

He knocked softly on the door.

Unfortunately, there was still no response.

This time he didn't open the door to look at it, because the man must have fallen.

If there is no fall, knocking on the door can naturally be discovered by the other party, which is related to the inheritance of the first demon gate, and it will not be indifferent.

Next, he knocked on the doors of fifty Nagu Towers in a row, all of which were more than a hundred trillion years old.

But none of them responded.

Originally, this was what he expected, but Li Chenggong's heart was still sad, because these ancestors were all amazing talents, all of them were powerful and powerful, and they left countless wonderful legends. Still, they fell, fell in the passage of time.

"Could it be that none of these towers have an ancestor still alive?"

Li Chenggong's face showed a look of disappointment, and his gaze slowly moved to those Nagu Towers that were less than a trillion years old, perhaps, among these Nagu Towers, there were still ancestors alive.

However, he was a person with an extremely firm heart, and he still did not stop, and continued to quickly knock on the Nagu Towers that had passed a hundred billion years.

Anyway, it's going to disturb the peace of the ancestors, so it's better to use this opportunity to find out how many ancestors are still alive.

So, he's going to probe all of the Nagu Towers at once.

Knock the oldest Nagu Towers first, and then knock on the Nagu Towers that are less than a trillion years old.

Otherwise, if an ancestor comes out, he will have no reason to knock on the door.

He picked up the pace.

Gradually, he knocked out all the Nagu Towers that were more than a hundred trillion years old, and only the first two remained.

When he walked up to the two Nagu Towers, his heart was already cold.

There are so many ancestors, so many peerless geniuses, and none of them survived.

And the two Nagu Pagodas in front of him, the one on the left is the Founding Patriarch of the Origin Demon Sect.

That's five hundred billion years away from today, and, according to legend, although it is incredibly powerful and can be immortal, it has long since fallen and was killed by eternal annihilation.

Otherwise, maybe he's still alive.

Therefore, there is no need to knock on this Nagu Pagoda door.

As for the Nagu Pagoda on the right, it is the second generation patriarch of the First Demon Gate, Li Yongcun, who is the son of Li Immortal, and the genius is incredible, even if his father is killed by Heng, he also successfully escaped Heng's pursuit with his disciples, and step by step the First Demon Gate has developed and expanded, becoming the most powerful sect in Chaos.

But this was also five trillion years ago.

After such a long time, it is impossible for Li Yongcun to be alive.

Therefore, there is no need to knock on this door.

"I don't believe that our Origin Demon Sect will be exterminated by a new sect."

Li Chenggong gritted his teeth and slowly turned around, going to knock on those Nagu Towers that were less than a trillion years old.

But at this moment, a cold voice sounded, "Why don't you knock on my door?" How fragile is your heart? ”

is a thunder that landed on Li Chenggong's head, and Li Chenggong would not be so shocked.

He froze like a fool, his heart beating wildly, and he turned around slowly, slowly, slowly, his eyes wide to the limit, staring at the Nagu Tower that belonged to Li Yongcun.

What made him ecstatic in his heart was that this tower door opened at some point, revealing an incomparably beautiful world.

"The 1,020,000th generation of the First Demon Sect Master has successfully visited the ancestor."

Li Chenggong forcibly suppressed the ecstasy in his heart, and suddenly knelt on the ground and shouted respectfully.

"Come in."

A cold voice came from within.

Li Chenggong got up and walked in mechanically.

To be honest, he still has the feeling of dreaming now, nearly five hundred billion years ago, the second generation patriarch of the First Demon Sect, Li Yongcun, is still alive? How is this possible? Could it be that he has cultivated to become constant?

As soon as he walked in, the tower door closed automatically.

Then he felt that his eyes were flowering, and he was transported to a strange place.

This should still belong to the Nagu Tower.

However, the scene in front of him made him completely dumbfounded.

Because, this is a wide field where some ordinary grains and vegetables are grown.

Ten farmers, barefoot and with their trouser legs rolled up, are planting rice in a field.

"What's going on? Have I reached the mortal world? ”

Li Chenggong's face showed disbelief.

"What kind of strong enemy did the First Demon Gate encounter?"

The ten peasants stopped planting the rice and walked up slowly, and sat down on a stone bench in a shed, and one of the tallest boys said in a faint voice with vicissitudes.

"Excuse me, who are you?"

Li Tiangao still couldn't believe that these ten farmers would be the ancestors of the First Demon Sect.

"Hehe......" The ten farmers all laughed faintly, and the young man took off his hat, revealing a face like a knife and axe, and said lightly: "Don't worry, we are all the ancestors of the First Demon Sect, and we are all surnamed Li, and we are your ancestors." They have all lived for more than a hundred trillion years, and they came to me from other Nagu Towers, and we comprehended the Great Dao together. So, you knocked on so many Nabone Tower doors, and no one responded. ”

"Oh my God, my God, there are still ten super powerful giants alive in our Origin Demon Sect, who have lived for more than a billion years, the ancestors of my Li family are really too powerful and geniuses." Li Chenggong shouted frantically in his heart, but his mouth was still a little incredulous: "You, you, you are Li Yongcun Ancestor?" ”

"Of course yes, is there anyone who dares to pretend to be impersonated?"

The young man's face was indifferent, without any anxiety, and the other nine people were also not anxious, they began to make tea slowly, looking really like a leisurely farmer.

"I, I, I just can't believe it, Ancestor, you've lived for more than five hundred trillion years, have you cultivated to become constant?" Li Chenggong was not worried about the threat of Yanhuangmen at all now, and continued to ask curiously.

"It's not so easy to cultivate to become constant. None of us have cultivated to that point. However, the catastrophe of heaven and earth will not kill us. Li Yongcun said softly.

There was no pride, as if, he was talking about a trivial thing.

"This, this, this, Ancestor, I feel that the Heaven and Earth Tribulation is terrifying, and it is more powerful every time, how can you survive hundreds of Heaven and Earth Tribulations?"

Li Chenggong was puzzled.

"It's simple." A big man with a full beard said lightly, "Put down the butcher's knife and become a Buddha on the spot, don't kill, don't kill, don't hide." The magnitude of the Heaven and Earth Tribulation becoming much slower, if it can continue to become stronger, it will naturally be able to survive countless Heaven and Earth Tribulations. ”

"God, is that so?"

Li Chenggong's face showed shock and ecstasy, but he was still stunned for a long time before he said, "Then isn't that any different from falling?" ”

"Bastard, there is hope when you are alive, as long as you cultivate to become constant, you can naturally go out and kill enough at one time, at that time, you will destroy all the giants of chaos, and the catastrophe of heaven and earth will not be able to help us. And if it falls, there is no hope. A giant with a face as white as silver shouted.

"Yes, yes, the juniors understand."

Li Chenggong nodded again and again, but his face showed a look of disappointment, if this was the case, wouldn't asking them for help delay their cultivation? Maybe let them fall?

"We haven't been out for trillions of years, and our slaves have all fallen. So, too, we can go out and collect some slaves. It doesn't affect us much. Li Yongcun said lightly, "Let's go, let's go and destroy the Yanhuang Gate, Zhang Dong and Liu Chao are still qualified to be our slaves." ”
