With a powerful spiritual perception, Cao Xu fiddled for a while and unlocked the door lock with a complex structure. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

After hearing the "click", he pressed his hands on the door and pushed hard. The steel door moved into the hand to reveal a small chamber that was only ten steps wide.

In the center of the chamber was a well-like facility, and on the well was a large winch, on which a small chain as thick as a child's arm was coiled.

Cao Xu turned the winch, and the iron chains on the disc continued to increase. The other end is obviously connected to the axle and other arrangements, and the chain can only be twisted inch by inch.

"Click", the chain can no longer be twisted, and then the twisted handle is locked.

Cao Xu waited patiently.

After a while, there was a sudden "rumbling" sound like thunder in the depths of his feet, and the two interlocking walls separating the southwest and northeast areas opened at the same time, and the passage to the treasure house in the east area slowly opened.

Cao Xu walked through the corridor and came to a circular stone room, with a round stone table in the center and eight stone chairs.

There is a map engraved on the stone table, which is full of pictures and texts, and the analysis is detailed, which intuitively shows the relationship between the underground treasure house and the Chang'an City on the ground.

The circular stone chamber has four ordinary wooden doors leading to the four treasure rooms, and under the tables are flint, flam, and paper coals to light the eight wall lamps evenly distributed on the walls of the surrounding chambers.

After the lights were turned on, Cao Xu checked them one by one and knew that Yang Gong's treasure was indeed worthy of its name.

These four stone chambers, each of which is as wide as a hundred paces, contain three weapons, and one contains treasures mainly gold.

All weapons were wrapped in a special oilcloth to prevent corrosion and moisture, and placed in thousands of sturdy wooden boxes.

According to rough estimates, there are more than 3,000 crossbow bows alone, and there are countless arrows. There are tens of thousands of other armor, knives, guns, swords, halberds, and other weapons, which are enough to assemble a strong force of 10,000 people.

The map on the stone table shows that there are four other tunnels in the vault, with entrances to each of the four storehouses, one of which leads to a hill outside the city.

The secret passage leading to the outside of the city is equipped with rails and iron cars to transport goods, and as long as the cable is twisted, the materials can be quickly transported outside the city. It's just that this so-called rapidity will take at least a day or two.

Afterwards, Cao Xu returned to the central stone room to look at the map on the table and found a way to seal the warehouse. He drove the trap to separate the fake vault to the south from the real vault to the east. In this way, even if someone finds the entrance to the well in the future, they will definitely not be able to touch the real library to the east.

This matter is over for the time being, and the next thing is the real goal of Cao Xu's trip.

I saw him grab the edge of the table with both hands and pull it up, and the stone table should rise two inches with his hands, making a soft sound. Slowly turning to the left, there was a sound of wheels grinding under the stone table.

One of the floors next to the stone table sank down, revealing a small space inside, and when I looked down, there was a small sealed copper jar inside.

The relics of the evil emperor are finally getting their hands on them.

Cao Xu stretched out his hand to touch the copper pot, and when he touched it slightly, his mind was immediately full of bloody and terrifying situations, and his ears seemed to hear the screams of thousands of unjust souls asking for their lives.

It is worthy of being an evil emperor relic, and it is really evil.

It is rumored that this evil emperor relic was originally a burial object found in an ancient tomb belonging to the Spring and Autumn Period and the Warring States Period in order to find a set of silk books about medicine.

When the Evil Emperor Relic was found by Xie Bo, it was placed under the back of the neck of the tomb owner's pillow, covered with blood spots, crystal mottled, because of the translucent nature of crystals, so it was classified as citrine, in fact, it is very different from any citrine.

What intrigued Xie Bo the most was that this crystal ball seemed to contain a certain strange power, and after Xie Bo's long-term experiments, he came up with an astonishing discovery, that is, the crystal ball has the strange property of absorbing and storing human true essence and essence.

Xie Bo was overjoyed by this discovery, and after years of research, he finally created a method of injecting Yuan Jing into the crystal ball.

At that time, he was not far from the time of his return, so before his death, he injected all the Yuan Essence into the crystal ball, and asked the next generation to find a way to extract the Yuan Essence in the ball. Since then, this crystal ball has been named "Holy Emperor Relic".

This brings the most headache problem of the Heavenly Evil Dao in the six sects of the Demon Sect, like Xie Bo is as knowledgeable and talented, extraordinary, and has great wisdom and wisdom as a person is rare to see in a hundred years, although the successors of the past generations have tried their best and tried every possible way, but they are still sitting on the treasure mountain, sharing less than a star and half of the benefits.

And because of the lack of a law, the relics continue to absorb all kinds of harmful or harmless vitality, making the problem more complicated and more difficult to solve. However, the evil emperors of the past dynasties, as long as they were not the deceased, would inject the essence into the relics according to Xie Bo's testament before they died, which also became the way of death chosen by the sect masters of the Heavenly Evil Dao.

Because of all kinds of changes, studying how to extract the relic's essence has become a highly dangerous thing, and if one is not good, there is often a risk of going mad. Occasionally, someone can extract the beneficial vitality from the relics, which can indeed multiply the power. However, how to extract the essence of the relics is still at a loss.

This mystery and mystery made the evil emperors of the past dynasties persevere, what is the essence of the hard work?

Taoism has the so-called three elements, which are the three lights of the sun, moon and stars in the sky, the three elements of water, fire and earth in the earth, and the three things of essence, qi and god in man.

The primordial spirit is a congenital little spiritual evolution, which determines the upper limit of a person's life expectancy;

Yuan Jing is the basis of the existence of acquired life, which determines the lower limit of a life expectancy;

Yuan Qi is a derivative change of these two and determines the state of a person's body.

The "Evil Emperor" Xiang Yutian, the talent of Tianzhong, cultivated the "Dao Heart Demon Cultivation Dafa", realized the method of extracting the Yuan Jing hidden in the relics of the Evil Emperor, faked his death to escape the world, escaped the red dust, and lived hard for hundreds of years, and then shattered the void and left.

The role of Yuan Jing is terrifying. This made Cao Xu extremely envious.

The gap between reincarnation and shattering the void is too great. Not to mention anything else, just having to re-cultivate in every life and start all over again is enough to make people arrogant. If you accidentally hang up when you are weak, you won't have a place to cry.

Cao Xu reached out and grabbed the handle of the copper pot and lifted it upwards vigorously. The magic sound was full of sounds, the illusions were numerous, and he was calm and unmoved.

Placing the copper pot on the table and slowly opening it, a strong evil aura suddenly rushed to his face, and the momentum was several times stronger than before.

Cao Xu stretched out his hand and inhaled, and a fist-sized yellow crystal slowly flew out of the mercury liquid in the copper jar.

This crystal seems to be hard and soft, and the translucent interior is faintly visible with a blood-red pattern that flows slowly like clouds and clouds, exuding a faint yellow light.

The moment the yellow crystal fell into the palm of his hand, Cao Xu only heard a "boom" in his ears, and the vast and endless evil qi surged wildly, like a roaring torrent, galloping and rolling, like a wild horse on the loose, galloping wantonly.
