During the walk, Kunlan occasionally stopped and would gently touch the rock wall with his hand. That gentle movement was almost like two different people from his usual style.

Even, in some places, this arrogant boy, who is actually about the same age as Tianyang, will stick out his tongue and gently lick the rocks.

After walking for a while, Cangdu couldn't help but said: "I didn't expect that you like to lick rocks."

Kunlan sneered: "You know nothing, hairy monster, do you know how the cave was formed?"

Cangdu snorted: "What a coincidence, I didn't take geology as an elective."

"If you don't understand, you don't understand." Kunlan patted the rock wall, "Caves, or caves, are usually the result of long-term deep erosion of groundwater in limestone areas. Each part of the limestone layer contains different amounts of lime, and the degree of erosion is different.

, the caves formed will be independent of each other and have various shapes.”

"But have you noticed that since we entered the cave passage, the height and width of the passage are almost the same. What does this mean?"

Tianyang stopped: "You want to say, this is a man-made cave."

Kunlan snapped his fingers: "Although I don't like Bai Mao, he is right, this is an artificial cave."

Cangdu sneered: "I thought you would come to such a brilliant conclusion, but this is the result? What's wrong with the man-made cave? The residents of the reverse world also like to run trains underground, why don't you dig an artificial cave under the city for them?

Cave?”

Kunlan folded his hands and supported the back of his head: "Only fools dig caves underground. A bad city would sink. Besides, these rock walls are smooth and clean, and they were obviously dug not long ago. As for who did it,

No need for me to say more, right?"

Tianyang frowned: "According to what you said, the cave was dug by the black people. But I have seen empty underground halls and irregular cave corridors down there. They don't look like they are man-made."

Kunlan shrugged his shoulders: "Nevermind, I didn't say that the entire cave system is man-made, so why don't you let the black people get through them? Don't say I didn't warn you, you'd better be careful. Since the black people

You can dig a hole here, and you can lay a trap here.”

Tianyang disagreed: "When we came up from the underground, we didn't encounter any traps."

Kunlan grinned slightly, revealing a tiger tooth: "Don't be naive, Bai Mao. Just because you haven't touched it before doesn't mean you don't have it. You've been explored twice before and after. Do you think the black people won't make arrangements?"

Cangdu crossed his arms over his chest: "You want to say that those things can also be used as remedies?"

Kunlan looked at him and asked: "Are the black people stupid? Oh, you usually come into contact with only one or two dangerous things. Those low-level things are indeed stupid. I don't blame you."

"What do you want to say!"

"If you can't hear what I'm saying, then you are really hopeless, Shaggy."

The sun touched my forehead, and these two guys started again.

"Shh!" Jiyu suddenly gestured in front, then lay down on the ground with his ears pressed against the cold surface of the cave, "There is a sound coming towards us..."

She suddenly looked towards a branch on the left!

Cangdu immediately set up his rifle, and with the help of the lighting accessories on the gun, he cast a beam of light into the deep and dark fork.

At this time, even Tianyang began to hear strange noises. When his ears caught the sound, the young man formed a picture of objects rolling in the passage.

After a moment, a dark, round shadow rolled down the slightly inclined road. When the light shone on it, a blurry face appeared in the light.

what is that?

This is almost the same question that everyone is thinking about at this moment! Kun Lan suddenly flashed into the fork in the road, with two turning blades already unsheathed, pointing in front of the blades, and the young man with blue hair and black eyes shouted arrogantly: "Let me do it!"

The stars are revealed and the two blades are intertwined.

A huge x-shaped sword light was imprinted on the object rolling from the fork in the road!

That thing scattered in all directions, and it turned out to be prowlers and mad dogs! They were wrapped into balls by some kind of power and rolled from somewhere on the fork in the road.

Although he was killed by Kunlan now, in fact, the blue-haired boy only killed a few prowlers and mad dogs. More monsters surged past him like a black torrent and headed towards the main road.

Knocked in.

For a moment, Tianyang's vision was completely occupied by these twisted and evil figures, and his ears were filled with the crazy and hoarse roars of monsters.

The boy's reaction was not slow either. Almost as soon as the monster jumped into the main road, a silver glow shone around him.

He casually picked up Ji Yu who was closest to him, and with a long retreat, he distanced himself from the black people who were like turbid waves.

Jiyu is a hunter class, and in such a narrow space, her role is limited.

If she is not brought out, the dense enemy group will swamp her in no time.

After Tianyang let go of his hand, Chiyue's sword was unsheathed, and the blade lit up with a crimson color. He pounced again, and with a flash of sword light, a mad dog was chopped into two pieces by him.

Next, Tianyang did not want to waste his energy, so Chiyue targeted the opponent's will cage. When the blade passed by, either the cage of these people of darkness was shattered, or their heads were split open.

In the midst of his busy schedule, Tianyang glanced ahead.

Cangdu and Kunlan also worked hard to defend themselves against the enemy.

In contrast, Kunlan's double blades were much more advantageous in this environment. The blue-haired boy turned the blade back and pressed it against his arm, spinning like a top.

Wherever this human top passed by, black people fell in droves.

However, Cangdu's Spring Water Sword was too long. Under such conditions, he could not use more powerful chopping movements. He could only use single-handed techniques, stabbing or picking, to break the black people's cage.

As a result, the efficiency is far inferior to that of Kunlan.

Tianyang killed another mad dog, and then several Xingsu arrows flew close to him, nailing a mad dog and three prowlers in front of him to death.

The young man looked back and saw that Jiyu had already opened his long bow and used his archery skills to cover the three of them.

At this time, screams and roars sounded from behind the passage, and it sounded like they were not the only four people who were attacked.

Tianyang guessed correctly, attacks like this occurred in many passages. Those ball-shaped objects formed by a large number of prowlers or mad dogs rolled in the complex cave network.

Once it collides with a human being, the force field restraining the black people will disappear, allowing a large number of soldiers to be immediately thrown into the battlefield.

Facing this kind of human sea tactic attack, the Ascendants were better off, but the ordinary soldiers in the squad suffered.

They didn't even have a chance to shoot, before they were overwhelmed by the black people who surged out, and were then bitten and torn apart by those things!

"Die! Die! Die! Die!"

The cave was filled with Kunlan's somewhat crazy shouts. The blue-haired boy's face was covered with the blood of the black people, but he didn't care at all. His expression was excited and he was killing crazily.

When he stopped, there were no dark people around Kun Lan, and the dark people who fell under his sword died in extremely tragic ways.

Some prowlers were cut off by him, but they did not die immediately. They still tried to crawl out of the pile of corpses, stretching out their arms to catch Kunlan's feet.

Kunlan turned the blade, jumped to these monsters, and pierced their cages.

When he broke through the cage of the last black citizen who was only half alive, Kunlan suddenly felt something and looked towards the cave ahead.

But the depths of the cave were dark and there seemed to be nothing. Kunlan took out a pistol and fired a flare in that direction.

Suddenly there was a bright light deep in the cave, allowing Kunlan to see a dark purple sphere floating towards him.

There is a layer of light flowing around the sphere, and the light actually looks a little viscous, like a rolling ball of mucus. Dots of orange light are constantly lighting up in the center of the sphere, and those orange lights gather towards the center, and finally disappear.

When the sphere approached, Kunlan immediately felt that he was being pulled in the direction of the sphere by an invisible force of gravity.

His pupils dilated slightly, he pressed on the handle of the turning blade, then swung the turning blade, and the long blade flew away with lightning, crashing into the purple ball with a touch of starry silver light.

The surface of the purple ball was immediately covered with orange cracks, and energy poured out from the cracks, turning into a dark purple fire cloud!

Boom!

There was a violent explosion in the passage, and the strong wind caused by the impact came oncoming, almost suffocating Kunlan.

He pressed the handle again, and the long blade shot flew back. It turned out that there was a special steel wire connecting the blade body and the handle.

Under the action of the fine machinery built into the handle, the long blade retracts, joins the handle, and re-forms the turning blade.

Kunlan looked at the blade body, and saw that the blade body made of composite materials had some signs of melting, and there were even purple stains remaining on the surface.

At this time, in the dust and smoke floating in front, there were four or five strange light balls with self-suction floating towards them.

Kunlan didn't dare to show off, so he retreated to the main road, helped Cangdu kill a mad dog, and shouted: "Be careful, the wizard is coming!"

The three members of the Raven Team changed their expressions upon hearing this, especially Tianyang, who had encountered this kind of black man several times.

But every time we meet, the wizard's image is slightly different, and his abilities are even different.

The only thing that is the same is that this kind of black people has a wide range of destructive means. It would be worst to bump into them in a place like a cave!

"Quick, let's go back to the captain and his friends!" Jiyu made a prompt decision and shot out a few more arrows, killing several black people around Tianyang and Cangdu, and then retreated.

Her judgment was very accurate, and she faced the wizard in such an extremely unfavorable environment.

Only Han Shu and Ning Yi, two captain-level sublimates, could deal with it.

After all, if the two classes of Fortress and God of War cooperate with each other, the combat power will not be as simple as one plus one.

Unexpectedly, just as the rain retreated, the ground behind her suddenly exploded, and a large cloud of purple fire spewed out, immediately blasting a huge hole in the passage.

That's not all, because of the explosion, the ground began to collapse. Just under this passage, there was an unfathomable underground crack!

Jiyu's face turned pale, he ran forward and shouted: "Run! Run quickly, you can't go back, and this place is going to collapse!"

Tianyang looked back, and sure enough, the passage was collapsing at a very fast speed. Under the cracked ground was a dark abyss. He didn't want to fall in again, so he immediately pulled up Jiyu and ran away.

Kunlan took the lead and opened the way in front. Tianyang and Jiyu ran in the middle, and Cangdu was behind.

There was another explosion behind him, and it turned out to be those purple light balls floating out from the fork in the road. They hit the surrounding rock walls, and the purple fire cloud that broke out accelerated the collapse of the passage.
Chapter completed!
