Even if Journey to the West really exists, it is a thing of the past, otherwise the relevant legends will not spread to the world.

But now the Monkey King in the mountains hasn't gone out to find immortals and visit the Tao, worshipping the Seven Great Sages, making trouble in the Heavenly Palace, and being pressed Five Fingers SX to learn scriptures, these things have naturally not happened yet.

This clearly does not match the realistic timeline.

"Master, because the Earth Immortal Realm has been sealed, its time dimension has actually been completely derailed from the outside world, and before the Earth Immortal Realm breaks through the seal and reconnects with the current universe, it can theoretically be connected to any time period of the Earth Immortal Realm. ”

The fairy replied.

"Any time period?"

Fang Yu's eyes suddenly lit up: "Doesn't that mean that I can freely travel through the past, present, and future of the Earth Immortal Realm?"

Although he didn't have a very clear understanding of the concept of the derailment of the time dimension mentioned by the fairy, he keenly grasped the main point.

"In theory, it's possible, but it's hard in practice. The fairy responded.

"Why?"

"This involves the Heavenly Dao of the Earth Immortal Realm......"

The fairy spirit gave a detailed explanation, so that Fang Yu probably figured out the key to this.

Theoretically, with the help of the power of the Earth Immortal Mirror, the fairy spirit can send him to any time period in the Earth Immortal Realm, but in practice, it does not always work.

Even if the Earth Immortal Realm is sealed, it is essentially still the Immortal Realm above the heavens, not something that anyone can knead at will, the will of the world cannot be bullied, and the laws of Heaven cannot be humiliated.

Even if Fang Yu had the protection of the Earth Immortal Mirror, if he wanted to enter the Earth Immortal Realm, he could only take the means of smuggling.

Moreover, this kind of smuggling is not allowed at any time, and only in some special periods can the conditions for smuggling be possible.

If you want to succeed in smuggling, the first condition is that you must hide from the Heavenly Dao of the Earth Immortal Realm.

Otherwise, you will only come in with your front foot, and your back foot will be discovered by the way of heaven, and what awaits you at that time will be either human calamity or heavenly punishment.

Unless you have the ability to resist the sky, you will only be taken away by a wave of natural and man-made disasters.

With small arms and legs like Fang Yu, there is no need to think about such a high-end and high-grade thing as going against the sky, it is not enough for God to be a thunderbolt.

Therefore, it is only during the special period of chaos that he has the opportunity to blend in.

This special period refers to the period of the Great Tribulation of Heaven and Earth.

To use an analogy, the will of heaven is similar to the immune system of people, but the immune system of the world.

It does not have a specific sense of autonomy itself, and some only eradicate harmful substances from the body, so as to maintain the instinct of physical health.

And the catastrophe of heaven and earth is like a human fever.

When there are too many harmful substances in the body and conventional measures are no longer effective, the immune system will clean up the body through unconventional means such as fever and fever.

Stowaways like Fang Yu are like foreign viruses.

Under normal circumstances, once entered, it is immediately detected by the immune system and then eradicated.

But during the fever period, the immune system is at its weakest and busiest, and its vigilance and defense against external viruses are at a low point, which becomes the easiest time to mix.

In the realm of earth immortals, there have been three catastrophes of heaven and earth since ancient times: the first tribulation of the dragon and the Han dynasty, the catastrophe of the lich and the catastrophe of the gods.

Among them, the Dragon and Han Tribulation caused by the Dragon, Phoenix, and Qilin Clans Hegemony and the Lich Tribulation caused by the Lich War all occurred in the ancient flood era, before the formation of the Earth Immortal Realm, Fang Yu couldn't go even if he wanted to.

Only the most recent god catastrophe can be visited.

But the Great Tribulation of the Gods was a catastrophe that swept through the heavens and the earth, and even the saints themselves ended up at the most intense time. Later, the Tongtian Sect Master, who lost his anxious eyes, almost overturned the table to destroy the world, so that the heavens and the earth would return to chaos and repeat the earth, water, fire, and wind.

In that era when the entire Three Realms killed the Mad Eye, it was very likely that he, a little shrimp, would not survive even a day before he had to receive a boxed lunch.

Even if he was lucky enough not to be strangled in the cradle, when the saints were gone, he, a little "extraterritorial heavenly demon", would not be able to escape the eyes of those saints, and he would probably not even know how to die at that time.

After all, the Journey to the West era has become his best choice.

First of all, the Journey to the West belongs to the aftermath of the Great Tribulation of the Gods, because the Journey to the West to learn scriptures and the spread of Buddhism to the East are all derived from the cause and effect left by the three religions and gods.

Affected by the aftermath of the catastrophe, Tianji fell into chaos again, giving Fang Yu the opportunity to smuggle in.

Moreover, since the Great War of the Gods, several saints have left the Earth Immortal Realm one after another, and most of the other great supernatural powers have also gone into hiding, so that the fledgling Sun Wukong can disrupt the Three Realms, and the risk and the period of the gods are much lower.

"That means I seem to have a lot of choices, but it's actually just such a choice, right?"

Fang Yu asked with a wry smile.

"That's right. ”

The fairy replied in his heart.

"Then how long can I stay in the Earth Immortal Realm this time?"

"Theoretically, you can stay as long as you want......"

"Well, don't talk about theory, just talk about practicality. ”

Seeing that the fairy spirit was the same routine again, Fang Yu directly interrupted.

"Actually, you can only stay here for a maximum of eighteen years. ”

Fang Yu couldn't help but be stunned when he heard this: "Why is it so short?"

"Master, your current spiritual cultivation is still too shallow to completely lock the true spirit, if you stay in the Earth Immortal Realm for too long, the true spirit will be assimilated by the Earth Immortal Realm, and then you will not be able to return to the real world. ”

"Anything else?"

Fang Yu was slightly stunned, and couldn't help frowning.

Although the cultivation environment and resources of the Earth Immortal Realm are far superior to those of the earth, his parents and relatives, and his own roots are all on the earth, so it is not okay if he does not go back.

"It must be eighteen years, can't you stay a little longer?"

"You have lived in the real world for a total of eighteen years, so you can't be in the Earth Immortal Realm for more than eighteen years, otherwise the true spirit is in danger of being eroded and assimilated by the laws of the world. ”

The fairy's answer was firm, and it was clear that there was no room for bargaining.

"It's only eighteen years......"

Fang Yu scratched his head.

Eighteen years is a long time, and a short time.

On Earth, this amount of time is almost enough for another generation of human beings.

But in the earth immortal realm where immortals and demons are all over the place, this time is probably not even enough for some immortals to retreat.

Originally, after Fang Yu knew that he had actually come to Journey to the West, he was planning to find an opportunity to have a good relationship with Sun Monkey's guy, and then follow his ass to get more benefits.

After all, in the early stage of Journey to the West, Sun Monkey's life is like a hanging, and the protagonist's aura is simply not too bright.

I wanted to ask the immortal to ask, and casually worshiped a master who was so awesome that he couldn't do it, and in just over ten years, he learned a skill that was enough to cross the three realms.
