The entrance to the underground treasure house was in a well in the courtyard, and Cao Xu quietly sneaked into the well. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoThe well water was cold and biting, which lifted his spirits.

Hold your breath and sink to the bottom of the well. Rubbing his eyebrows lightly, his spiritual power is like mercury pouring into the ground, pervasive.

After a few moments, all the mechanisms in this place were clear.

He reached out and grabbed a stone protruding from the wall of the well and pressed it hard.

There was a "rolling" sound, and a large piece of the well wall above the water surface slowly moved away, revealing a tunnel that could accommodate one person.

When the cave first opened, the breath inside was very stuffy, and it was easy to cause suffocation, but this did not pose any threat to Cao Xu at all.

After being reborn and reinventing the real body. It was only a matter of time before he became a Qi Cultivator, he was only half a step away from congenital consummation, and he could easily turn his outer breath into inner breathing.

The tunnel first stretched up to five zhang obliquely, and then changed to downward oblique extension, and it was quite steep.

After Cao Xu broke several mechanisms along the way, he finally came to a corridor where a person could walk upright.

As far as the eye can see, the corridor stretches straight up, and at the end is a misty blue light. When I got closer, it turned out to be six pearls radiating blue light.

In the center of the six pearls is a portal made of stainless steel, with a copper ring on it.

Cao Xu was silently lucky, and stretched out his hand to write eight big characters on the stone wall on the side, "Poor road Qingxuan, come here." ”

If there are latecomers, let them slowly guess who this Qingxuan Daoist is.

Standing in front of the steel door, after a little induction, Cao Xu reached out and grabbed the steel ring on the door, and pulled hard, revealing the steel cable connected to the steel ring.

The left and right hands are swapped, and the steel ring in the hand is rotated to the left, and when the third turn, there is a "bell" sound from the steel door, which is crisp and loud.

I tried to push the steel door, and sure enough, it opened.

Another corridor appeared in front of me, the end of which was submerged into darkness, and it was difficult to fathom the depth of the distance, but the air was very fresh.

Cao Xu looked down, only to see that the stone quality of the floor behind the door was different, and with a wave of his hand, a splitting palm force fell on it.

I only heard a sound of a machine, and ten extra-long and extra-thick steel arrows seemed to shoot from the darkness at the other end in a chaotic manner, and the arrows that broke through the air brought a terrible whistling sound, which was even more piercing in this silent underground corridor.

The arrows will cover all the corridors that only allow people to stand, and unless Cao Xu can become as thin as paper, he will not want to avoid it. This kind of super power crossbow launched by the machine is a hundred times more powerful than the crossbow arrows issued by ordinary crossbow bows.

Cao Xu smiled slightly, and a long and narrow sword with a pitch-black body suddenly appeared in his left hand. This is his former sidepiece, the Shadow Sword.

The sword was unsheathed, but it did not make the slightest sound, because the scabbard was lined with a special leather, which not only eliminated the sound, but also served to maintain the sword.

A little bit of cold light intertwined the layers of sword curtains, and there was a chaotic sound of "bell", Cao Xu returned the sword to the sheath, and all the powerful arrows that came from the roar flew over his body and fell into the tunnel behind him.

His right arm felt a little sore, and Cao Xu praised it: "It's a powerful mechanism." "The reason why he touched the mechanism was not purely to eat and support, but to seal the entrance to the well when he came.

After trying the power of the mechanism here, Cao Xu didn't dare to be careless, jumped over the floor with the mechanism behind the steel door, and came all the way to the end of the corridor.

I saw that at the end of the corridor was a wall full of holes, densely packed with holes, and when I looked closely, there were arrows in the holes, which could be shot out at any time.

Although he had known the situation here for a long time, after really seeing it, Cao Xu still felt that his scalp was numb. It's a shame that the mechanism here is not a thousand arrows, otherwise he wouldn't dare to risk anything.

Turning left ahead is another long corridor, in which there are no mechanisms. At the end is a wide sealed basement with vents at all four corners of the roof.

There are more than ten boxes placed in a row on both sides, and there are dozens of weapon racks on the wall, full of various weapons, but they are just ordinary goods, and all of them are rusty and moldy, and no one wants to give them away.

Cao Xu walked into the stone room and lifted the lid of a box, which was full of things like ancient jade treasures, which seemed to be worth a lot of money. Picking up two boxes at random, he turned and returned to the second hallway with the traps.

Putting the two boxes one on the left and one on the right, Cao Xu stood in front of the wall densely covered with arrow holes, inserted two fingers into the two arrow holes respectively, and then lifted his luck up.

With the "squeak" of the axle wheels, the hole wall rose upward, revealing a square stone chamber about twenty paces wide, and in the center of the stone chamber were countless crossbow bows.

The wall directly opposite was a live wall, Cao Xu moved the two boxes next to him, and after the first box was placed horizontally, he put the second box upright on top of the first box.

Exiting the stone chamber, Cao Xu came to the wall opposite the fake warehouse, which was also a living wall.

The Yang Gong Treasure House is the entrance to the west, the fake treasury to the south, the hub to the north, and the treasure to the east.

The two living walls on the north and east sides are an "interlocking" model, which opens one to the other.

These two interlocking walls divide the south-west axis of the cross-axis and the northeast axis into two zones, which are both entrances and deceptions.

If you want to enter the real library of the Northeast Axis, you must cooperate with each other to successfully open the two living walls.

Although Cao Xu was alone at this time, this organ could not stop him.

I saw that his left hand pressed against the living wall in the north, and with a wave of his right hand, a palm force flew out, and when he was about to hit the crossbow of the machine, the palm force suddenly turned out of thin air, made a bend, and hit the wooden box that Cao Xu had placed vertically before.

The wooden box was stressed, and it toppled forward, hitting the living wall to the east.

At the same time, Cao Xu's left hand also exerted force together.

I only heard a "click", and the two walls on the east and north sides fell into an inch at the same time, and the mechanism was opened.

Cao Xu took a step back and pushed towards the living wall in front of him again, only to hear a "rumbling" sound, the living wall swayed inward, and Cao Xu took advantage of the trend to move forward.

"Peng!", the living wall behind Cao Xu was closed.

Then there was a "click", and it was even locked, which was so ingenious that it was unbelievable.

Like history repeating itself, another corridor stretches forward in front of you, and at the end is the misty light of the night pearl.

Through the clear light, you can see that the floor of this corridor is paved with two gray bricks of different colors and shades, which is different from the previous three corridors.

Cao Xu stepped on the light-colored bricks and pushed forward, about fifty steps later, under the reflection of three night pearls in each of the left and right rows, it was indeed a door, but there was no steel ring, only a round button, the edge of the cloth was engraved with a number, a total of forty-nine grids, and there was a red dot engraved on the door wall above the button.
