The successive system masters were not clear about the legends of later generations, which made them unable to start and find the origin of antiquity, so this secret still needs to be solved by Lu Chen.

On the way, Lu Chen closed himself up after entering the Variety Chariot.

took out the black box of this auction and looked at it carefully, for fear of missing a trace of corners, every detail.

The black wooden box, it looks a little rotten, ordinary and uninteresting, such a box, even if it is thrown on the street, no one wants to look at it, but Lu Chen took it down with ten thousand and one Saint Dao Heavenly Crystals.

The Emperor Dao Celestial Crystal, which is one grade shorter than the Holy Dao Heavenly Crystal, is a large amount of money for a monk, which can be called an astronomical amount, and it is extremely difficult for a small sect to come up with a few thousand Imperial Dao Celestial Crystals at once, let alone the Holy Dao Celestial Crystal.

With such a huge fortune, buying such a black box is considered a loser by everyone, and only Lu Chen himself knows the weight of this black box.

Looking at the black box in his hand, for a long time, the corners of Lu Chen's mouth curled slightly, revealing a smile.

That's right, the material of this black box is indeed ordinary, but this is just the appearance, as Lu Chen expected, there is a big secret in this box.

The ordinary material has a name that is not unfamiliar, ancient wood!

That's right, the material of this box that looks like it has decayed is ancient wood, it is a wood that is born like this, even if it is separated by 10,000 years, 100,000 years, millions of years, it is still the same, and it will never change.

Ancient rotten wood, there is also a characteristic, that is, it can seal all the breath without leaking, which is also some great power in the Tianmu world, and the emperor preserves the most precious natural treasure wood.

This also makes everyone think that this is really a rotten wooden box.

If it weren't for this, Lu Chen wouldn't be able to get this box, and even if he did, he would have paid a huge fortune.

For everyone in the human world, ancient rotten wood is indeed uncommon, but if this ancient rotten wood reaches the Tianmu realm, although it is not said that it is everywhere, there are many people who will know it.

Just now, Lu Chen observed it all over his body and determined that this was the ancient rotten wood of the Tianmu Realm, and he had a new understanding of the value of this box.

"Buzz!"

The runes in his hands skyrocketed, and one rune after another jumped, as if a naughty elf was spinning around the entire black box.

One by one, the elves quickly devoured the ancient rotten wood, and after a moment, all the ancient rotten wood covering the entire black box was devoured.

Ancient wood is as hard as divine iron, and the knife and axe will not leave any traces.

There are great enlightened people in the Tianmu Realm who have researched a set of secret methods for the characteristics of this wood, which can decompose and eat this ancient rotten wood, and this secret method is what Lu Chen is using now.

"Wood Eater!" that's the name of this secret method.

Under the hands of the wood-devouring hand, the ancient rotten wood was directly eaten away, revealing its true face.

Suddenly, a majestic atmosphere rushed to the face, majestic atmosphere, like thunder, like a river bursting the embankment, surging endlessly.

The majestic life force filled with this majestic aura completely penetrated the box in front of him and rushed out.

"What a majestic vitality!" Feeling this aura, even Lu Chen was slightly moved, such an aura was only one point weaker than his World Tree.

Without hesitation, Lu Chen directly opened the box, and suddenly a piece of black wood came into view.

It is as black as ink, black and shiny, and its rich black seems to make people fall into the infinite darkness at a glance.

"This is!" Seeing the black wood in front of him, even Lu Chen laughed all of a sudden, staring at it with a solemn face, his expression changing.

"Sacred Tree Jianmu!"

That's right, this piece of black wood Lu Chen is familiar with, but Lu Chen, who is almost obsessed with Kunlun Mountain in later generations, has seen all the legends about Kunlun Mountain countless times.

Among them, there is the legend of this piece of black wood.

The sacred tree is said to be a sacred tree in myths and legends, standing in the center of heaven and earth, the top of Kunlun.

Jianmu, a ladder of its own, has the fate of the gods, and is the only way to the heavenly court.

According to legend, the three emperors and five emperors such as Xuanyuan Yellow Emperor, Emperor Yan, and Fuxi in later generations all relied on sacred trees to build trees, going back and forth between the human world and the heavenly world.

It is the link between the Terrans and the heavenly realm.

"How could Jianmu appear, how could it appear here, the Flood Desolate Continent, the Age of Mythology, is really inextricably linked to this world!" Lu Chen muttered to himself, frowning slightly, unable to figure it out.

The most strange thing for him is that the things in the myths and legends of the later generations of the flood and famine era have appeared in this world one after another, but this world has no record of them, not even those big people, which is really strange.

It's as if the people of that era have disappeared out of thin air, and the various treasures they use will be discovered from time to time.

The current history of the Nine Realms and Ten Thousand Domains seems to be very different from reality, and there must be something wrong in some link.

History has skewed.

At this time, he couldn't help but think of a legend, this thing definitely has a great connection with the Demon Clan's Divine Court.

Otherwise, this thing would not have appeared in the tomb of the Purple Bee Clan.

The Demon Clan's Divine Court and his party are imperative.

First, he wants to take a look at the connection between the Purple Bee Demon Ancestor and the Spirit Sealing Insect, and now, there is an added item, that is, whether this thing is the "Tianwei Source Key".

Legend has it that the Tianwei Source Key is related to the origin of the entire Tianmu Realm, and it has always existed in legends and has never appeared in the world.

Back then, because of this origin, the entire Tianmu Realm set off a treasure hunting craze, and it almost turned the entire Tianmu Realm upside down.

If this thing is really the "Tianwei Source Key", then Lu Chen will make a lot of money this time.

The whole black wood is black and gloomy, but it gives people a sense of vitality and infinite vitality.

This vitality is not the law of life, but its own vitality, which exists in the whole black wood.

It's hard to imagine what kind of tenacious vitality this sacred tree had back then, and it's hard to imagine who could cut it off.

It's all unsolved mystery.

After studying for a while, Lu Chen's eyebrows opened, put away the black wood, his eyes swept out of the car, looked at the mountains and mountains in front of him, and groaned.

This piece of black wood, itself still needs to be studied,

It's not easy to figure out the mystery.

"Young master, there is a woman asking to see you!" Suddenly, a voice came.

"Oh?" Lu Chen was stunned for a moment, then walked out of the retreat space and came to the Variety Chariot, "Who?"

"The people of the Four Elephant Divine Palace, who else can it be, fox spirit!" Mu Yu pouted and cursed.

"Let her in!" Lu Chen sat down and said slowly, quite puzzled in his heart.
