Four thousand years ago, the human world at that time was still not much changed from Cheng Hao's time, but everything became abnormal from a major event at that time.

About 4,300 years ago today, a major event suddenly broke out in the human realm, that is, the collapse of the boundary and the invasion of foreign races!

At that time, Bai Yujing's realm fell apart for some reason, and countless strange creatures with strange appearances and powerful strength poured into the human realm.

Those things were like ferocious locusts, and no human plants or trees survived wherever they passed.

It is really to the extent that the chickens and dogs are not left.

They will even feed directly on humans, which is a real demon!

Cheng Hao frowned slightly when he heard this, so he asked, "What does that monster look like?"

"Looks?" Zhou Zhizhang pondered for a moment and said: "I just saw the description in the ancient books, saying that their appearance is not very different from the ordinary human race, but the whole body is hairless, the hun (shēn) presents a strange gray-white color, and there is a huge tail behind it, the fangs in the mouth are sharp, and the fingers and toes have sharp claws, they (shēn) do not have any aura and martial arts cultivation, but their strength and speed are extremely strong and terrifying, even the powerful warriors in our human world are not their opponents!"

"Sure enough, it's the Xiao clan. Cheng Hao secretly said in his heart: "If the boundary gully breaks through, it can pour in a large number of Xiao clans, then it can be seen that the boundary gully is really completely broken, otherwise it would be great if a few powerful individuals can come over." ”

Indeed, the boundary gully can be broken through, as long as it reaches the level of a martial immortal, or is a powerful creature equivalent to a martial immortal, then it can break through the boundary gully and pass through

Go to the other realms.

Of course, unless such a breakthrough gully is a martial god powerhouse, it will still suffer a certain amount of damage when breaking through the gully.

However, such a large-scale invasion is very abnormal, and it seems as if the boundary is completely non-existent.

Cheng Hao had never even heard of such a thing.

"That catastrophe directly led to the death of sixty percent of the creatures in our human world, sixty percent! And not just the population, but the living creatures!"

Zhou Zhizhang also showed a terrifying look on his face when he said this.

Sixty percent of creatures......

Cheng Hao sighed secretly, if the Xiao clan really rushed into the human realm, then it was indeed able to do this.

The environment in the Xiao Realm is harsh, and slightly weaker individuals will not have a chance to grow up at all, and they will naturally be eliminated and die when they are still infants.

Therefore, those who can grow up to adulthood are all very strong and terrifying powerhouses, although they do not have any aura (shēn) and do not practice martial arts, that is, with their strong (shēn) bodies honed in the harsh environment, it is enough to compete with martial artists.

The powerful of the Xiao clan does have the existence equivalent of a martial god.

For example, Emperor Xiao's Zong Zhi Gu.

It is conceivable what it would be like for the Xiao people, who had never even eaten a full meal in the Xiao Realm, to suddenly come to the human realm where there are abundant products.

He did not doubt Zhou Zhizhang's description at all, indeed, what the Xiao tribe had passed, and all things did not give birth to that was the normal (qíng) situation.

Moreover, the Xiao people do not know how to produce, let alone build, they are a race that only knows destruction, and they have no foresight at all.

But it's actually true, life

In a ghost place like the Xiao Realm, it's uncertain whether you can still breathe tomorrow if you're alive today, everyone naturally thinks about the things in front of you, who will think about what will happen in years or even decades?

So they only know how to loot and destroy.

"It wasn't until later that our warriors in the human world had to use all their resources and strength to build the first city in the human world at that time, Tianya City, as the forefront of the human world to protect the human world, resist the group of gray demons, and resist the seven years of resistance, and also protect the safety of the people in the human world for seven years, but this Tianya City is now unknown where it is, and there are all kinds of legends. ”

Cheng Hao's interest was brought up when he heard it, he was able to resist such terrifying guys as the Xiao clan for seven years, then this Tianya City is much more powerful than an imperial capital like Youyunjing.

But why don't you know the exact location?

Zhou Zhizhang said: "After all, the time when that incident (qíng) happened was too long, and later, in fact, Tianya City also suffered a heavy blow, if it wasn't for the arrival of the gods later, then our human race is afraid that it will be completely destroyed." ”

"The gods are coming?" Cheng Hao raised his eyebrows and looked at Zhou Zhizhang.

Zhou Zhizhang nodded and said: "Yes, just when Tianya City was about to be broken, the sky cracked, and dozens of powerful gods descended on the world, helping us repel the invasion of the gray demons, and also led our human race to counterattack, all the way back to Bai Yujing, and drove the damned devils back into the gully, and then the gods started to arrange the protection of the gully, and re-closed the passage of the gully, so that the human world after us has more than 4,000 years of prosperity, so you should always know now."

Bai: Why does Bai Yujing's vision make everyone so nervous?"

Cheng Hao nodded, he really didn't know this history, at least it was not recorded in the Cheng family's library, especially the Tianya City had never been mentioned.

It seems that it is also because of the age, and because most of the martial artists in the human world are now limited to the martial emperor, and their lifespan is limited, so many things are still broken.

I'm afraid that only a sect like Xianmen can retain some records of the past.

"Then, what if it happens, well, I mean what if, if the real boundary is opened again?" Cheng Hao looked up at Zhou Zhizhang.

Zhou Zhizhang's face suddenly turned pale, and he said with a wry smile: "At that time, I was afraid that it was really the end (rì) of our human race, and the gods had not appeared again for a long time. ”

"Is it......" Cheng Hao muttered, it seemed that he really didn't have much time left.

And this realm vision really has to be explored, just in case!

With such a thought, Cheng Hao said to the uncle and grandson who was replying: "Elder uncle and grandson, the stakes are very high, and the survival of our entire human race is involved, there can be no more hesitation at this time, we must enter the Baiyujing Realm to see what is happening (qíng)!"

Shusun Tong nodded slightly after listening, Cheng Hao was right, such a big event, their personal safety is nothing.

"But, but that Liniu ......" Zhou Zhizhang wanted to say something.

Cheng Hao said: "Lychee cows usually don't take the initiative to attack humans, so I want to come."

It may have been attacked by the warriors of the Luoxia Sect before, which is why he is so irritable. ”
