Just when Guo Yang couldn't take his eyes off it, the virtual monster rolled again, and its body was a big circle smaller, only about two zhang high, and the black mist was even thicker, and there were even some signs of condensation.

The monster seemed to have a much clearer mind, grinning anthropomorphically at Guo Yang, and swooped down on the blood jade bone fragment.

Guo Yang subconsciously wanted to take back the blood jade bone fragment, but unexpectedly, the monster's speed was too fast, and it pounced on Guo Yang's hand in an instant. Before he could react, the monster had already sunk into the crystal clear bone.

This is all something that happened in a thought, and Guo Yang couldn't stop it at all.

He pinched the piece of blood jade bone and cried out bitterly when he looked at it. The blood jade bone fragment was originally crystal clear, and it contained a touch of red, which looked quite amazing. But at this moment, next to the red, there is a mess of black silk, which looks really a bit eye-catching.

"You brutes, the thief's heart is not dead, and you finally got into the blood jade bone fragment. Well, now it's okay, I guess the demons think that I sent them a fake blood jade bone piece! Guo Yang shook his head and smiled bitterly, but there was really no way, this monster transformed by thousands of demon souls was too fast, and he didn't have time to stop it.

After the black silk pattern was integrated into the blood jade bone fragment, it was honest and motionless, as if it was originally a part of the bone fragment.

Guo Yang studied it carefully for a long time, and finally sighed, put it into the storage bag, and planned to go out and ask Anu or Ah Jiu to take someone to clean and arrange the hall.

Suddenly, Guo Yang's face changed slightly and he stopped.

He heard a fine | buzzing", but hundreds of little red-billed hummingbirds flew back. Guo Yang's face was happy, and he waved his hand to recall the birds that were slightly larger than the bees.

The hummingbirds buzzed around Guo Yang's head twice, and flew quickly towards the stone wall on the side of the main hall with a buzzing sound.

Guo Yang followed closely, faintly excited in his heart, it seems that these little guys have really found something good.

When they arrived at the stone wall, those hummingbirds flew directly high, flickered three or four feet away, and suddenly disappeared.

Guo Yang is a little strange, the stone wall looks exactly the same as the stone wall in other places, it is gray and collapsed, it is inconspicuous, there are no cracks or anything like that, where is the hummingbird?

He groaned slightly, mobilized the power of the spirit and demon in his body, and climbed up.

When he arrived at the place where the hummingbird disappeared, Guo Yang took a closer look and suddenly realized. Originally, the stone wall here looks no different from below, but after climbing up, I noticed that there is a fist-sized ventilation hole here, and three or four feet away from the ventilation hole, there is a hidden stone door, if it is not for the guidance of hummingbirds, even if Guo Yang climbs up, it will be swept over, and he will not notice it at all.

Guo Yang nodded secretly, impressed by the scheming of the first king of the Southern Yan Ancient Kingdom, these untraceable details are the biggest characteristics of a heroic character, not how great things he has done.

Guo Yang took out an extremely thin knife, slowly inserted it into the slit, and tried for nearly half an hour before he found a little doorway. This stone door is controlled by a mechanism that can only be opened outward, but the mechanism that locks the door is behind the door.

This kind of stone door, even if it is occasionally found, has nowhere to focus on the smooth stone wall, and it will not be opened for a while.

After figuring out the joints, Guo Yang gave up the idea of opening the stone door directly and began to look for the mechanism carefully.

He tried all the nearby stone walls within a range of seven or eight feet, but there was still nothing he could do. As soon as he turned around, he took the entire hall into his eyes and began to ponder.

The architectural pattern of this hall is different from all the building shapes that Guo Yang has seen, and suddenly it looks square, but at this moment when climbing on a high place, it is found that all the stone walls are somewhat arcanut, more like a delicately designed arc-shaped building, each point, there is a unique symmetrical point.

Guo Yang half-squinted, trying his best to find the symmetry, and finally found that there was an identical ventilation hole on the stone wall opposite dozens of zhang away.

He climbed down from the stone wall, quickly came to the opposite stone wall, swam up like a gecko, and reached into the vent.

His fingers touched a fist-sized cavern that seemed to lead directly above the ground. Guo Yang groped little by little, and finally found a thumb-sized concave.

Somewhat nervously, he touched one finger and pressed it gently.

Motionless.

With a little more force, it still doesn't move.

Guo Yang pressed it with all his might, and the concave spot did not react at all, as if it was originally a small pit on the stone that was accidentally knocked off.

Guo Yang was unwilling, and the power of the spirit and demon in his luck body condensed into his fingertips and pressed it hard.

The dimple suddenly loosened and sank a full finger, and at the same time, there was a soft "click" inside.

Guo Yang was overjoyed, looked at the opposite side, and sure enough, he saw a slight crack on the stone wall.

He flew down, and after a few ups and downs, he reached the opposite stone wall, quickly climbed up, took out an iron tool the thickness of a finger and inserted it, and with a gentle prie, the stone door opened silently.

Because the hummingbird led the way before, Guo Yang didn't think much about it, jumped in directly, and stepped into the stone gate.

Behind the door is a passage that can only be bent over, paved with bluestone steps, which feels quite dry, and stretches all the way down, I don't know how many steps.

Guo Yang bent his waist and cautiously descended for half an hour, only then did he enter a labyrinth-like place. The roads here are all over the place, and every cave is almost identical, and it is impossible to distinguish the real from the fake for a while.

Guo Yang shook his head and sighed, and said in his heart: "This traitor, it seems that he was really afraid of being found by the demon people back then, and he directly built a dungeon into a mouse hole!" ”

While lamenting the man's caution, he opened his mouth to make several strange buzzing sounds, somewhat similar to the buzzing of the little red-billed hummingbird.

With a buzz, hundreds of small hummingbirds flew out of a rat-hole-like passage, hovered and flew in again. Guo Yang hurriedly followed, and under the guidance of the hummingbird, he made a cup of tea, and finally came to a stone gate again.

This stone door is the same as the one that just entered the main hall, and there is an extremely intricate Zhong Dingwen pattern on it. Guo Yang hesitated for a moment, took out the knife, and cut the palm of his hand, allowing the blood to flow out and gather in the palm of his hand.

He flew up and poured the ball of blood into the pattern, but his palm didn't dare to press it directly. Last time, he suffered a small loss at the gate of the main hall, and Guo Yang also began to be cautious.

When the Zhong Dingwen pattern saw the blood, it suddenly lit up, and a dark red light shone brightly, and those complicated strokes began to connect end to end and flow at high speed. There was a muffled boom, and the stone door opened.

Guo Yang didn't dare to rush in, and took advantage of the light of the mutton fat torch in his hand to take a look at the situation inside, and then stepped inside.

The stone door rumbled and slowly closed behind him. Guo Yang smiled bitterly, if you come out and go in in the future, you have to prepare a bleeding lamb in advance, otherwise, it will be a little unbearable to open the door with your own blood every time.

The space here is not very large, about one or twenty zhang in size, but it is a natural karst cave transformed into an underground palace building. There are stone tables, stone benches, stone couches, and stone frames in the cave, and the best thing is that a finger-thick trickle flows down a stalactite stalagmite, and a tiny pool is formed on the stone floor.

Xiaotan is made in heaven, the perennial water flow is injected, and its water level does not increase or decrease, so that Guo Yang, who has never seen anything in the world, is very interested, squatting on the side of the small pool, scratching his ears and cheeks, and thinking about it for a long time without figuring out, where did the excess water flow.

"This traitor really knows how to pick a place, is this the so-called Immortal Cave Mansion?" Guo Yang observed the small waterhole for a while, and then got up to explore the entire stone cave.

On the stone table, there is a set of bronze wine vessels of the previous generation, the shape is simple, a total of 24 pieces such as the Jue Yao Gui, etc., the sizes are different, the ornaments are mostly birds, beasts and fish patterns, and Guo Yang, a great expert in bronze wine vessels, is amazed, and he stops playing for a long time.

On the stone frame, there are animal skins and tortoise shells in a mess, and there are also some unknown animal bones, which are also engraved with intricate patterns and words, which seem to be older than Zhong Dingwen.

At the innermost part of the cave, there is a simple stone door, which is also designed to be extremely delicate and secretive, and is designed from a natural stalactite. At first, Guo Yang didn't notice it, but when he took out a jar of sake from the storage bag and was about to enjoy the bronze wine vessel, he suddenly felt that something was wrong, and he always felt that he was missing something.

He got up and searched the cave again, and found the simplest and most confusing stone door.
