Lin Jiu listened patiently to Kong Xuan's words.

Obviously, what Kong Xuan is talking about is not only some secrets about the human race, but also some mysteries about the level of Taiyi.

This was something that ordinary cultivators could not touch, and it was also a lesson that Lin Jiu lacked.

And now, the arrival of Kong Xuan has made up for Lin Jiu's lesson.

The era of the primeval flood - to be precise, it is the era before the demon clan, and there are ten thousand clans in the earth, and there are big clans.

And the so-called big clan is the race in the clan that can give birth to Taiyi Daojun.

And the core of whether Taiyi Daojun can be born is not in resources, but in another deeper and more obscure thing.

Spiritual core.

After all, in that era, the resources for cultivation were available everywhere, and there were many great supernatural powers who preached everywhere, and for practitioners, both the method of cultivation and the resources of cultivation were commonplace.

Therefore, in that era, what limited whether or not a group could support the existence of Taiyi Daojun was the spiritual core, which was difficult to exhaust in words.

The reason why the Demon Emperor is great is that after he merged all the races of the earth into one and turned into the demon race, he took the demon race as a whole and refined the spiritual core that belongs to the demon race, or the concept of the demon race - all things on the earth, and those who have spirits are demons.

So since then, there is no distinction between the lands, and any demon clan between the lands has the possibility of touching Taiyi.

At least in theory.

And the reason why the human race, as the protagonist of the earth in the past, has never been feared by others, and even many great cultivators do not take the ordinary human race in their eyes, is because the human race lacks its own spiritual core.

Both: What is a human being? What is a human being?

There is no answer to this question, even if the human race is the protagonist of the earth, but it is only the humiliated race in the era before the demon race.

Without this spiritual core, those Taigu emperors of the human race can exert the subtleties of the Taiyi realm with the blessing of some secret methods, but they are not Taiyi after all.

But after the Terran Fire Cloud Cave was reopened, Kong Xuan knew that the situation of the Terran was completely different from the beginning.

The missing core of the human race was actually filled by those Holy Emperor Ancestors of the human race at some point.

From now on, the human race is the real protagonist, among the human race, if a human emperor is born, then this human emperor will definitely be able to touch the boundary of the supreme saint just like the original demon emperor.

Even the possibility of this human emperor achieving the supreme saint is much greater than that of the demon emperor.

After all, in the era of the Ancient Demon Emperor, there was no room for the eight Saint Supremes to appear.

And today's era is a brand-new era that will give birth to the supreme saint.

"Zhu Zi chases each other, and all schools of thought shine."

"Now it seems that the so-called competition of a hundred schools of thought is really the process of those Holy Emperor ancestors of the human race, who gave up their cultivation to return to the mortal world and shape the backbone of the human race."

Kong Xuan sighed.

At this point, he was also embarrassed.

When he knew that the Terran had shaped his backbone, he didn't need to think about it, he could be sure that the time node when the Terran shaped the backbone must be the era when the hundreds of schools of thought were scorching and shining.

At that time, it was the most brilliant era of the human race.

Although the sons of the earth are only mortals, although they have never touched the cultivation at all, they have never avoided birth, old age, sickness and death, although they have only been turned into dust and ashes in only a few decades.

But their spirit, their philosophy, is brilliant.

Even when these sons walked on the earth, many immortals and gods descended to the earth and incarnated, followed the sons, listened to their teachings, and felt their spirits.

It is precisely because of this that there has always been a rumor among the earth.

Speaking of those hundred schools, there are people who are the embodiment of the supreme saint.

And now Kong Xuan looked back at that splendid era again, and suddenly realized that those sons of the hundred schools and countless brilliant thoughts were the ancestors of the Holy Emperors of the human race, who gave up immortality and risked the danger of being wiped out to return to the earth, so as to melt the spiritual internal friction process of the human race.

"It's a pity that I don't know what the spiritual inner channel of the human race is, otherwise, there should be more promising." Kong Xuan.

The spiritual core of the demon clan, or the existence basis of the demon clan, is the sentence 'between the earth, there are spirits for demons'.

"Is the spiritual core of the human race...... Lin Jiu also groaned.

In the void, the five-colored light does not bloom, and under the five-colored light, everything in the void, whether it is the wind of the void or some mixed and filthy things mixed with the wind of the void, will all turn into powder.

It didn't take long for the outline of the Flood Desolate True Realm to be in sight.

In the past, when he traveled between different places, he felt that he was close to the Flood Desolation True Realm by taking Kong Xuan's five-color boat at this time, which was naturally completely different.

In the past, although Lin Jiu also entered and exited the Flood Desolation True Realm, the feeling that the Flood Desolation True Realm gave him was just ordinary.

At this time, under the illumination of the five-colored light, this desolate true realm was as if it had been disguised by the dust stripped of everything by the five-colored light, revealing its true posture.

Just looking at the outline of the Flood Desolation True Realm, the unprecedented pressure was already head-on towards Lin Jiu.

It was his Dao Fruit, under the pressure of this Flood Desolate True Realm, it seemed to be creaking with great difficulty, as if it was about to collapse at any time.

And in the outline of this desolate real world, there are countless shadowy figures, fighting and shouting in the mist, like the silhouette of the long river of time and space surrounding the desolate real world, falling on it.

When Lin Jiu peeked at this scene, the silhouettes in those time and space seemed to be aware of Lin Jiu's existence, and they all killed him.

In an instant, it can be said that the sun and moon shook and the stars fell.

The blood qi on Lin Jiu's body was mixed with murderous aura, and it also surged out.

Next to him, Kong Xuan looked at Lin Jiu, his face was calm, and after a while, he swayed the five-colored light, twisting all the silhouettes into pieces.

"How does it feel?" Kong Xuan asked.

"What is this?" Lin Jiu asked with palpitations.

The time of Fang Cai, for Kong Xuan, may only be a moment, but in Lin Jiu's perception, it seems that thousands of years have passed - fighting with the silhouette of the primeval figure, he has not experienced it, when he was in charge of the demon flag, he stepped into the demon banner and fought with those ancient demon gods, he himself can't remember.

But the fight in the demon banner and the fight between his mind at this moment are different from the earth.

The fight in the Demon Banner was dangerous, but for Lin Jiu, it was also easy.

And in the silhouette of Fang Cai, although it is only for a moment, the danger in the meantime is already thousands of times that of the demon flag.

"This is the true Flood Realm." Kong Xuan said with a smile.
