Although he wasted a lot of time because he had to dodge various traps along the way, Li Yuan didn't stop along the way and rushed to the treasure house before dark, if he didn't get this drawing, maybe even if he knew that this was the treasure house, there was no way to open the door.

He walked to a carved pattern that was fifty meters away from the gate, looked at it and couldn't see anything unusual, and couldn't help but shake his head. It seems that the wisdom of this predecessor is really not to be underestimated, if it were not for the fact that the flower carved here in the marking of the drawing is a mechanism, he would not have been able to find it.

Li Yuan reached out and grabbed the middle of several flowers, and then after two seconds of this passage, a vibration sounded, and Li Yuan could feel that there was a mechanism running behind the wall.

When he returned to the gate of the treasure house, he saw that the stone door outside was slowly lifted, revealing two delicate iron doors inside. There were two keyhole-like holes on the iron door, and Li Yuan took out the two keys he had found in a room not far away and inserted them.

This is the room of the chamber responsible for guarding the treasure house, and the residences of the two chamberlains are at both ends, that is, there are detailed marks on the drawings, otherwise Li Yuan would not have had a way.

I inserted the two keys together and turned them at the same time, only to see that the patterns on the two iron doors that seemed to be one began to rotate continuously, and gradually the two doors slowly opened.

However, Li Yuan didn't walk in, and this treasure house didn't know how long it hadn't been opened, even if it wasn't completely sealed, the air inside definitely wouldn't smell too good.

Li Yuan casually took out a wooden stick and lit it and threw it in, only to see the fire flickering for a moment, and then quickly extinguished.

"The wind is coming. Li Yuan stretched out his hand to the inside of the door, and a gust of wind blew in, and then soon Li Yuan felt that the inside did not seem to be sealed, because the wind blowing in seemed to pass through from the other side.

However, Li Yuan understood after a little thought, this is probably designed a long time ago, the door on this side is open, and the ventilation on the other side is also open, which saves Li Yuan a lot of things.

Li Yuan walked in slowly, then took out the jade slip found in the chamberlain guarding the treasure vault and took it out, and directly stopped all the mechanisms in the treasure house inside.

After walking in, Li Yuan found that it was not as he thought, there was a huge warehouse full of treasures and secret treasures.

Instead, it is a long hallway, flanked by doors, each marked with them. Li Yuan took a closer look and found that what was marked on it was the type and grade of the items stored inside.

Li Yuan paid attention to it and found that the more he walked inside, the more precious the things inside became, and he walked all the way for nearly ten minutes before he reached the end of the treasure house, thinking about it, the width was probably nearly a hundred meters, and the underground treasure house almost hollowed out the entire underground of the palace.

He pushed open the innermost door, on which were written saint-level exercises, Li Yuan's heart was on fire, he didn't know what the effect of these exercises was, but the strength of these people was not weak, as long as he looked at the spiritual weapons that were rare in the desolate world, he could know that this disappeared civilization might be a powerful civilization that was not inferior to the current civilization.

Since this is the case, the kung fu they left behind must have a certain reference effect, Li Yuan walked in and saw that there were only a few bookshelves in the huge space inside, and dozens of jade slips were sparsely stored on them.

Li Yuan stretched out his hand to take one down and checked it, only to see that it said "Nine Turns Xuangong", Li Yuan was shocked in his heart, he didn't expect the first thing he saw to be such an awesome exercise. Li Yuan simply didn't check them one by one, and took all the jade slips, a total of thirty-six jade slips, he wrapped these jade slips with a piece of animal skin, and then carefully stored them in the space ring.

Then walked towards the opposite door, only to see that the door of the opposite door was written "Spirit Weapon, Innate", Li Yuan was excited in his heart, in the desolate world, the spirit weapon is also divided into innate and acquired, but the innate spirit weapon is too few, and the vast majority of the entire continent is afraid that most of them have not even listened to it, so when everyone talks about the spirit weapon, they will not say that the innate and acquired, even if it is the acquired spirit weapon, it is something that makes them greedy.

Li Yuan pushed the door in, and there were not bookshelves inside, but platforms one after another, and on each platform there was a spiritual weapon suspended on it.

Even if Li Yuan didn't know what these spiritual artifacts were, the light shining on them also let Li Yuan know that it was not a simple thing. Li Yuan suppressed the excitement in his heart and carefully put it into the space ring along with the platform.

Then Li Yuan searched frantically along the way, and gradually Li Yuan was even a little numb, and the things that could be included in the palace treasury, even the worst ones were spirit stones that could provide aura.

There is one difference with the universal currency of the human race, the soul stone, that is, the soul power is an acquired power, and the spiritual power is innate. The human race can condense the soul stone by itself, but there is no way to condense the spirit stone, only the heaven and earth can naturally form.

He doesn't have any attributes, and it has the same effect on every cultivator, not like a soul stone, if he encounters a soul stone with the opposite attributes, the soul power conversion rate may be less than half.

However, there are too few spirit stones on the Longhuang Continent, and the spirit stones mined every year are not even enough to consume, so it is impossible to use them as currency. But looking at the spirit stones piled up in several rooms in this treasure house, it reminded Li Yuan of the gold coins in his previous life, which were also piled up in the treasure house like this, I am afraid that at that time, spirit stones were currency.

Maybe it was because the mining was too much at that time that it became so rare, and now it's all cheap Li Yuan.

Such a rich harvest also made Li Yuan wonder in his heart, what happened to make such a powerful civilization be wiped out silently.

One only needs to look at the palace and the other houses in the castle to see that there may be some dilapidation due to time, but there is absolutely no sign of war. The places where the weapons are left inside are also the places where the guards should stand when they are guarding.

In other words, these people may be directly killed in an instant, and there is no power to resist, and even most people may not know how they died.

Thinking of this, he couldn't help frowning a little, the people in this city are definitely not weak, even if there is no sage, but there will definitely be no less strong people who are beyond the realm, but even so, they are still killed so quietly, even the sage does not have this ability.

In the end, Li Yuan smiled bitterly, he really ate radish and didn't worry about it, he was just a little person who had just melted into the spirit realm, so he should leave such a tall matter to his cheap master to solve.
