(Updated late today, guilty)

The so-called Tianyuan Square Array is a series of formations used on the battlefield. This formation uses the middle as the fulcrum and spreads radioactively toward the surroundings. As the name suggests, the center is square, and the outer periphery is layer by layer like waves. Of course, Tianyuan Square Array also has variants, that is, the outside square and the inner circle. The specific method depends on the form of the battlefield and the understanding of the person who set up the array.

The Tianyuan Earth Formation can be attacked or defended. Last time, Huang Shang was on the third floor of the ancient tomb and saw the mad demon being besieged by more than a hundred mechas, the formation deployer used the Tianyuan Earth Formation with square inside and round inside and outside. This formation method mainly focuses on attack.

The inner circle and the outer square mainly focus on defense. On the battlefield, there is enough space between each layer, and even the position between each ray is quite particular. Half of it is composed of a round cake for every five people, similar to a cut piece of cake. There is also a gap between each round cake. There is a gap between layers, and between the round cakes. This is naturally for the rapid passage of other people, including commanders and support troops. The size of each round cake depends on the specific form, rather than constant, otherwise it will become a copy or copying.

Through exploration, Huang Shang initially concluded that this was a defensive cave chamber with a round inner and square outer outer body, and the body was in the center of the cave chamber.

On the battlefield, if you want to attack from all directions or protect extremely important people or things, it is the most appropriate method to adopt a round and local formation. At this time, the commander of the central army is in the center, or the important people are arranged in the center, and you can remotely control the command, calmly dispatch, and allocate troops according to the enemy in different directions and the progress of the battle.

Therefore, the most direct and difficult part of breaking this formation is the heart of the formation, also called the formation eye. Once the formation eye is broken, the entire formation will be broken without attacking.

Obviously, the condensed version of the Tianyuan Earth Array here is completely different from the real formation on the battlefield. It’s just that someone built this secret room according to the model of the Tianyuan Earth Array, and revealed the location of the array eye very obscurely.

"Sister..., all sides of this place have been blocked, and we may not be able to get out." Huang Shang shouted loudly to Suo Jiao who was guarding the entrance.

Suo Jiao glanced at Huang Shang without saying a word.

She couldn't speak, but the mad demon was waiting outside.

She rolled her eyes to Huang Shang, because Huang Shang was too reckless and spoke loudly in the darkness. Wouldn't she be exposed, and she was eavesdropped on by the madman?

The most important thing is that she rolled her eyes because Huang Shang's unskilled name - sister.

Although Suo Jiao is a little older than Huang Shang, he is an unmarried woman after all. He will make her look old and mature by saying that she is old and mature. Most girls still hope to be called her sister, even if she is older than a man.

Oh...

The madman above the secret room stopped covering it and began to scream, but no matter how much he screamed, he did not dare to go down to the secret room easily.

The entrance to the secret room was originally not small, but during the closing process, he himself forcibly prevented the thick stone slab from closing the entrance of the hole, which resulted in the failure of the mechanism. Only half of the entrance size left was barely enough to allow an adult to slowly enter.

But if you enter slowly, will the person below give him so long?

The madman kept stepping on the hard rocks under his feet. Under his violent kick, the entire cave began to shake constantly, and many small stones slid down from the top of the cave and the hole, and even the rocks under his feet were stamped with a lot of stone chips.

Huang Shang was not idle in the secret room. He groped in the darkness to the dry corpse. He turned to the foot of the corpse and respectfully worshiped several times. Nothing else, death is the greatest, and the messenger is older than him.

Of course, the words left by the deceased on the stone slab can also indicate hope for life to yourself. Even if you cannot go out, it doesn’t matter if you worship.

Afterwards, Huang Shang groped to the side of the corpse, bent down and carried the corpse away from its original position, and carefully placed it on the edge of the hole inside.

The moment Huang Shang carried the body away, circles of white light appeared on the round top of the originally dark secret room. Although the ring light was not very strong, there was no problem illuminating the secret room.

The lights of these circles finally gathered in the center of the secret room - that is, where the corpse was just now.

Huang Shang rubbed his eyes and found that there was a wooden wedge about the size of a thumb in the position of the corpse, standing upright under the corpse. After the corpse was taken away, the wooden wedge was still standing upright in the distance.

And under the wooden wedge, there is a line of blood-red fonts saying: Those who drag out will die!

Huang Shang walked up and squatted down and looked carefully, and found that why these four shocking words still look so dazzling and not faded? It is because these four words are like the words on the stone slab on it, and they are forced to be engraved with external force. Unlike the words above, the grooves of these four words are filled with blood. After the blood coagulates, it is in a closed space for a long time, so after drying up, but the red still exists.

"I know I'm going to die in the clouds. If I'm lucky, I'll be troubled to transport my body to the Crescent Cave to bury it, so I'll thank you very much!"

Huang Shang bent down and stood on the edge of the wooden wedge and muttered softly.

"Oh, I'm dead, I'm lonely here. If I can go out, I'll transport you to the Crescent Cave."

Huang Shang muttered, while carefully checking the central area, because it must be where the array eye is.

"Click!"

A small stone shot in from the entrance, hitting the hole wall of the secret room, and suddenly shattered.

Immediately afterwards, countless small stones shot in from the entrance, and the shooting position was getting closer and closer to Huang Shang's position.

For such a remote disposal by the madman, Suo Jiao, who was hiding by the stone wall, was powerless because there was light in the secret room, and the madman was in a much dim position. It was like peeping at the room on a dark night to turn on the lights, which could make the people in the house look real, but the people in the house knew nothing about the darkness outside.

"What are you doing? Get out of here!"

Suo Jiao suddenly made a sound to remind Huang Shang, but she immediately exposed her position as soon as she made a sound. A hard rock the size of a fist roared and shot towards Suo Jiao from the entrance.

Originally, we had to shoot from outside to Suo Jiao's position, and we had to grasp the angle and force extremely accurately in order to achieve it.

But who is the madman?

Suo Jiao reacted very quickly, and the black dragon sword in his hand raised his hand toward the flying stones. The horizontal block was larger than the contact area that was cut, and the possibility of flying stones was greater.

when…

boom…

Suo Jiao never expected that the stone that the madman shot in this time was not ordinary gravel, but a kind of pebbles with a hard texture.

After being knocked away by Suo Jiao's Black Dragon Sword, the stone flew straight to the top of the secret room, and after hitting the top of the secret room, it made a huge sound.

The entire secret room was shaken, and the inside of the secret room began to shake. A stone as big as a palm fell down from the center of the top, hitting the wooden wedge directly, hitting the wooden wedge and sank into the ground.

Huang Shang, who flashed to the side, looked up at the top and found that the falling stone was not knocked out by impact, but was originally an independent stone. However, the shape of the stone and the hole at the top were quite well matched. In addition, the stone and the top were gray. If you don’t get close and observe carefully, you will not be able to find that there is a shaking stone on the top.

Rumble...

After a moment of silence, the entire secret room began to shake constantly, and a huge sound resounded throughout the earth. In the direction of the corpse, a black hole that was one person tall and two feet wide suddenly appeared. A humid and cold wind poured in from the black hole frantically. A sound of noose dragging heavy objects came from the black hole, empty and monotonous. As this sound approached, the air conditioning that poured in from the black hole became larger and larger, as if the air conditioning outside the black hole was backlogged by something and had to escape from here.

"Bang bang bang..."

At the entrance guarded by Suojiao, a violent explosion began, and countless white air waves burst out from the entrance, and half of the madman's body had entered the secret room.

Hearing the movement in the secret room, the mad demon didn't dare to wait any longer. At the risk of being attacked, he also wanted to come down and leave together. Oh, no, he left by himself.
