This period of history has long been reduced to myths and legends in many battles!

Lu Xuan also inadvertently learned in his previous life that in this life, almost no one on the earth knew about this period of the past.

Even how the Earth Cultivation Realm, which has an extremely brilliant cultivation civilization, declined, in fact, ordinary people don't know.

Even now, Lu Xuan's family can be regarded as a family entrenched at the apex of the entire cultivation world, and it stands to reason that the many mysteries of the entire cultivation world cannot be regarded as secrets to them.

Lu Xuan had people copying the classics of various families very early, of course, they did not involve specific cultivation cheats, but some of the predecessors' codexes, which were available in all aspects, although they did not involve the core secrets, but they were still extremely precious.

It's just that ordinary people can't really absorb what they need from it.

However, in the cultivation world, there is also a special profession, that is, treasure hunters, these hunters are often the best among the loose cultivators, specifically looking for some ancient rumors, many ancient rumors contain some treasure information.

They can find key information from it, and then find the treasure, and Lu Xuan also worked part-time as a treasure hunter in his previous life.

It was with these rumors, as well as the codexes of various predecessors, that Lu Xuan found a lot of treasures, although he also experienced hardships and dangers, and even died in his life.

However, the materials obtained from these treasures greatly supported Lu Xuan's cultivation.

In Lu Xuan's previous life, he was far from being as happy as he was in this life, he stood at the top of the world almost all the time, and he had never had the share of others fleeing for his life, and no one else forced him to escape for his life.

Because of this, Lu Xuan knew that those seemingly useless codexes were very important strategic resources.

Lu Xuan has also been collecting these resources over the years!

Especially with Lu Xuan's current prestige, just asking for these seemingly useless codexes, the various sects naturally won't resist, and there is no need to resist.

Anyway, it's not a practice cheat.

And when everyone in the Lu family heard Lu Xuan say this, they finally realized that there was actually such a past.

However, hearing Lu Xuan say this, everyone was even more worried in their hearts.

If it is really according to what Lu Xuan said, then the outside world must be very dangerous!

At the beginning, such a powerful earth cultivation world was actually hit hard like this, and it declined.

You can imagine what a terrible battle it was!

If Lu Xuan goes out, obviously, there is no way to guarantee safety at all!

"Brother, can't you not go out?" Lu Guoguo said with some worry.

"Yes, do you have to go out?" Lu Tiancheng said, his face showing a little worry.

Lu Xuan shook his head and said, "The world is like this, I can't help it!"

In the Earth Federation and the Cave Heaven Blessed Land, Lu Xuan was already the master of the number one Tianzi.

It can even be said that there is no opponent in the world.

But this level is not enough to satisfy Lu Xuan.

Especially after going through the experience of becoming a Heavenly Venerable in his previous life, Lu Xuan would not be satisfied with just the cultivation of the Transformation God Realm.

"If there is only the earth's cultivation civilization in the world, then forget it, but there are too many cultivation civilizations in the world, and now that the earth's aura is recovering, originally this is just a border wasteland, but as the earth's aura continues to recover, it will enter the eyes of many people with a heart, rather than waiting until that time and then trying to deal with it, it is better to prepare in advance!" Lu Xuan said.

He knew that all this was inevitable, in his previous life, many celestial arrogances outside the territory had descended, and the earth had become their hunting ground.

And the Earth Federation had just been established at that time, and it had just begun to integrate the forces of the earth and the Cave Heaven Blessed Land, and it was completely powerless to block the infiltration of those extraterritorial forces.

The entire Earth Cultivation Realm suffered heavy casualties!

Lu Xuan also struggled to survive in such a great world, and finally chose to fight into the starry sky to face the world's heroes.

If in the previous life, he could walk away and ignore the lives and deaths of others, then in this life, this is no longer feasible.

The Lu family is now a top-level family in the Earth Federation and the Cave Heaven Blessed Land.

Not a small person!

Once the forces outside the territory invade, then the Lu family is the absolute first to bear the brunt!

If they still want to rule the earth, the Lu family must be the target of their eradication!

Directly eradicate the Lu family, then the entire Cave Heaven Blessed Land and the Earth Federation will naturally be leaderless and self-defeating.

Lu Xuan had to have strong strength to be able to block their hand reaching out to the earth when foreign forces invaded in the future.

And this also means that Lu Xuan must leave the earth, and he can't raise a real dragon in shallow water.

The earth's cultivation resources were limited, and it was impossible to provide Lu Xuan with enough resources to allow him to grow rapidly.

Even if she has the memory of her previous life and has the realm cultivation of Tianzun, in the absence of resources, it is still difficult for a clever woman to cook without rice.

So he has to go to a world that is strong enough for him to grow!

"I'm preparing for the future!" Lu Xuan said. "I'm leaving, but you have to stay, in addition to ensuring that the Cave Heaven and Earth are integrated into the Earth Federation, you must also step up your cultivation, the future will not be smooth sailing, the current calm is only temporary, when many behemoths in the universe react, the earth will become their meal, and at that time, we must have enough ability to cut off the black hand that stretches out to the earth!"

Lu Xuan looked at his family and disciple Yun Ling'er and said, because they are not like Lu Xuan, although they are extremely talented and their physique is also very amazing, they do not have enough cultivation experience.

Therefore, it is absolutely no problem to practice at the speed of the earth's spiritual energy recovery!

And there will indeed be many dangers outside the territory, and Lu Xuan doesn't want his family to get involved in these dangers.

If there is any danger, just let him experience it alone!

Seeing Lu Xuan's expression so serious, everyone also knew that Lu Xuan had already made a decision, and no one could make him change what Lu Xuan had decided.

"But you don't have to think too much, I won't leave for a while, I still have to retreat for a while, enough for you to make a breakthrough in your cultivation, and at that time, even without me, you can control the situation!" Lu Xuan said.

Everyone in the Lu family left one after another, and suddenly learned that Lu Xuan was leaving, and even learned that there might be a universe-level force coming across the domain in the future, and they had a strong sense of crisis in their hearts, and they left to retreat and practice.

Only Lu Xuan's mother, Liu Wanrong, remained.
