The white jade bricks on the ground moved away, and a black cave appeared, with a staircase about one and a half meters wide, and a forty-five degree oblique angle extending downward into the darkness in a diffuse arc.

Yun Yanuan was puzzled and asked, "Why did you go underground?" Why don't you go straight inside the tree? ”

Ke Xin glanced at the towering tree, and then at the slightly arc-shaped steps under the black hole and said:

"This step should go all the way down around the big tree, the purpose should be to bypass the roots of the big tree, and the person who set up this mechanism doesn't want to damage the roots of this big tree, so I guess this big tree is a fossil of an ancient giant tree, which should be correct."

Yun Yanuan nodded and said, "Then it seems that this passage needs to enter below the root of the big tree, and then turn upward, let's go, pay attention to safety!" ”

It was very dark under the cave, Yun Yanuan hurriedly took out the third eye of Candle Jiuyin, and a cloud of cold light scattered out, but he could easily see the range of two or three meters in front of him.

The stairs of the corridor are relatively narrow, and several people line up, and Yun Yanuan takes the lead and gets into the tunnel.

The walls on either side of the staircase are carved with frescoes, which are basically war patterns, and the warriors use strange weapons, like long knives, but the blades start to curve forward from the upper third of the hilt.

Although Yun Yanuan had never seen this kind of weapon, he knew that the function of such an arc was mainly conducive to slashing, and he could easily cut off the enemy's head.

"The shape of this knife is very similar to the ancient Egyptian Khpash sickle, but the Khpash sickle is much shorter than the scythe on the fresco."

Kexin looked at it for a while and said.

"Such a long knife is very good for chopping, but it is also limited to chopping, only suitable for the battlefield, what a strange team, is it just to cut off the opponent's head? Ha ha! ”

Yun Yanuan said with a smile and continued to walk forward.

He said this based on Chinese martial arts, in fact, the application of this Kehpash sickle knife on the battlefield is very powerful, the sickle bend can hook the shield, and the thick back bend makes the slash powerful and the acceleration is great.

But such tactics and moves, when encountering the spear team in ancient China, it is estimated that they can only be tortured and killed. One is that the sickle is short, and the red tassel spear is long, and it is an inch long and an inch strong.

Second, the barrel of the Chinese spear is very tough and can be bent, and the control ability of the curved arc of this sickle is completely useless, so this sickle is not a very successful blade.

Kexin studied the murals as she walked, and she looked at them almost without blinking, as if the attraction of these murals was like a man seeing a woman without clothes.

"Look at the dead bodies on this mural, all of them have no heads, and their heads have been cut off! What a strange war, does this perverted team only cut off heads when they kill people? ”

Ke Xin shook his head and said, looking puzzled. Yes, it doesn't take that much effort to cut off the head at all, and it must be cut off. It's a thankless task.

A person's head is not so easy to cut off, it is not as good as a shot in the stomach, it is really not a throat cut, why do you have to cut off the head!

In ancient times, there was a punishment of beheading, all at three o'clock in the afternoon, when the yang energy was at its peak, cutting off the head of the prisoner, as an executioner, that was professionally trained, starting with technical work.

They were all thick-backed ghost-headed knives, which weighed far more than sickles, but even then, these executioners had to apprentice for a long time before they could master the art of falling head-to-head.

Once there is a knife and the head does not fall, then the executioner will also lose his job. This shows how difficult it is to cut off a person's head.

Battlefield fighting, killing the enemy with the most effort and speed is the most correct tactic, like this must look at the opponent's head tactics, it is estimated that it can also scare and scare people, the most idiotic tactics.

After walking down nearly forty or fifty meters deep, the murals on both sides suddenly disappeared, and the hole in the ground became wider, and the third line of sight of Candle Jiuyin was limited, and it was impossible to see the limits on both sides, but it could clearly see everything within two or three meters of the vicinity.

The five people were nailed to the ground, speechless for a long time, looking at the things on both sides, and gasped.

The mural ended, replaced by a mountain of dried bones, which were so close to the five of them that they could be touched without paying attention.

Looking at these dried corpses up close now, an indescribable sense of fear trembled strongly in the depths of my heart.

The corpses were supposed to be buried slaves or prisoners of war, as they all had no heads, and looking at the neat wounds on the neck bones, it was obvious that they had been cut off with a knife.

There is no sunlight for many years, and the cave is located in the center of the crater, and the geothermal roasting makes it very dry, and the outside moisture cannot enter, creating a desert-like environment.

Without dampness, there is no oxidation, so the corpses did not decay into dry bones, but into a headless dried corpse.

They wore kudzu or linen clothes, some of them wore leather armor on their shoulders, and the style was very simple, that is, kudzu cloth or linen cloth nearly two people long, with a round hole in the middle, put it on their heads, and tie it with a belt.

In addition, without any other clothes and no underwear, Yun Yanuan knew at this moment that after being dehydrated, he was really small.

"All male corpses, all without heads! These are not slaves, they are supposed to be warriors who died on the battlefield. And these warriors belong to one camp, and you can see by looking at the clothes and body shape that these people belong to one race. Ke Xin looked at it for a while and said.

"Is it to be buried with an enemy killed on the battlefield?" Ami Se said in surprise.

"I don't know, but these corpses are so neatly dressed and placed in a regular manner, it's really not like the attitude towards mortal enemies in ancient times, so I'm more inclined to use my own soldiers to bury!" Ke Xin looked at the mountains of dried corpses and talked eloquently.

But these words made the five people all covered with chills and goosebumps.

"It's too mad, don't you bury your own soldiers! It's so inhuman! Diana shook her head and cursed.

Ke Xin put on a simple glove made of the skin of Candle Jiuyin, and lifted the linen clothes on a corpse in front of him, and as a result, these seemingly complete linen clothes turned directly into dust under the touch.

A few people covered their noses, for fear that the dust would get into their nostrils.

"Don't touch it, it's thousands of years old, it will turn into dust when you touch it, I don't want to suck these dirty things in my stomach!" Yun Yanuan looked at Ke Xin and said.

"What do you know, I'm called a scientific expedition, don't be noisy, be quiet, I'll take a closer look!"

Ke Xin looked back and forth at the dried corpse whose clothes had turned to ashes, and then pointed to the chest of the shriveled and blackened corpse and said, "You see, this person was cut off after he died, and his fatal wound is here, and there is a fist-sized wound in his chest. Look at the laceration around the wound, it should be a blunt force injury. ”

Yun Yanuan also looked closer for a while, and suddenly opened his mouth in surprise and said: "This is indeed a blunt weapon, because this is a wound caused by the palm finger, this person's heart should be scratched......"
