After falling into the cave, the ground above his head collapsed and closed again. They found it pitch black inside, with only faint echoes echoing in their ears. I felt a chill hit me, and when I looked up, the stalactites were arranged in a staggered manner, and the water droplets were dripping down the stone pillars. Lin Weiyin asked Ai Chen, "What kind of place is this?" Why is it so cold? ”

Ai Chen said: "This is a karst cave, formed by the water in the underground river dissolving the limestone over a long period of time. ”

They walked forward step by step, occasionally illuminating the front with the flint in their hands. Suddenly, they noticed a behemoth not far ahead, crawling slowly.

Ai Chen exclaimed, "The ancient centipede insect, which can reach 5 meters in length, is similar in appearance to the modern centipede, and is one of the first invertebrates to appear on land, and almost no animal treats them as a meal. It is strange how this animal, which lived more than 300 million years ago, suddenly appeared in this cave. ”

Ai Chen's heart tightened, and he cautiously approached the behemoth. By the light of the flint, he could see the object for what it really was—a giant centipede. The centipede was five meters long, as wide as a city wall, and exuded a fishy smell. Ai Chen trembled with fright and wanted to turn around and run away, but his feet were already entangled by centipedes and he couldn't move.

The centipede slowly approached Ai Chen, and Ai Chen's heart was extremely desperate. However, at this moment, the centipede suddenly opened its mouth, revealing a bottomless mouth. Ai Chen hurriedly threw the flint into the centipede's mouth, and Ai Chen took the opportunity to break free from the restraints and turned around and ran without hesitation.

The centipede is a flat strip with a total of 22 links. head dark red or reddish-brown, covered with a cephalic plate, anterior ends flanked by antennae and a pair of jaws; The first dorsal plate of the trunk is the same color as the head plate, and the rest are brownish-green or dark green, shiny, and there are often two longitudinal groove lines on the 4th~20th dorsal plate; From the second section onwards, there is a pair of feet on both sides, in the shape of a curved hook, at least hundreds of feet.

Lin Weiyin took a deep breath, forced her composure, and took out a small bottle from her backpack, which contained a white liquid. She quickly opened the cap of the bottle and squirted at the centipede. The liquid made a "hissing" sound, and the centipede's body trembled violently, and finally, at that moment, Luo Zhengding was terrified, and he fled back to the cave with a crawl.

Lin Weiyin walked unhurriedly to the centipede's side, took a closer look, and found that it was not dead, but was just anesthetized by the liquid. She pulled out a small tin box from her backpack, which contained a white powder. She quickly poured a little on the centipede, and the centipede's body immediately stopped trembling and lay there quietly.

Luo Zhengding sat on the ground in shock, gasped and said, "You are really amazing, if it weren't for you, we would be miserable." ”

Lin Weiyin smiled and said, "It's okay, it's just that we practiced a little more." ”

Suddenly, Luo Zhengding suddenly thought of something again, "Wait! What is that powder? ”

Lin Weiyin explained with a smile: "That's one of our special medicine powders, which can anesthetize any monster. ”

Luo Zhengding relieved himself, "I see, then let's go quickly, I'm afraid that monster is still nearby." ”

Lin Weiyin nodded, and they continued to walk forward. After walking for a while, Luo Zhengding suddenly stopped, "Wait! I felt as if something was watching us. ”

Lin Weiyin looked around vigilantly, "I feel it too, don't be afraid, it may be our illusion." ”

I saw a huge centipede appear in front of me. Her eyes widened and she felt a wave of fear. The centipede slowly walked towards her, its hundred legs swaying like a whip. Lin Weiyin took a deep breath, drew her sword, and prepared to fight.

Lin Weiyin found that the centipede had venom on each leg, and its body was so hard that ordinary swords could not attack its interior. She began to think about how to defeat the powerful centipede.

Lin Weiyin suddenly felt a strong aura of danger, she frowned and looked at Luo Zhengding and Jiang Lengyan, and reminded in a low voice: "I feel a strong danger, we must get out of here as soon as possible." ”

Luo Zhengding was holding a spear, and Jiang Lengyan was holding a long sword, and they started a fierce battle with the giant centipede. Luo Zhengding suddenly stabbed out his spear, but was easily dodged by the giant centipede.

Jiang Lengyan swung her long sword and slashed at the centipede's body, because the centipede's armor was thick, cutting out sparks of "bell, bell", but she was easily repelled by the sharp thorns on the centipede's tail. For a moment, both of them were in a difficult situation. Seeing this, Lin Weiyin brandished her sword, trying to attract the centipede's attention and create an opportunity for the two.

After a fierce battle, the three finally found the weak point of the giant centipede - the abdomen. Luo Zhengding decisively raised his spear and rushed towards the centipede's abdomen. He stabbed the spear hard, but it was bounced back by the centipede's powerful force.

Seeing this, Jiang Lengyan brandished her long sword and violently attacked the tail of the centipede. His attack wounded the centipede, but it couldn't stop it from advancing. Seeing this, Lin Weiyin brandished her sword and rushed towards the centipede's head. Her attack caused the centipede to twist its body in pain, but the giant centipede remained unmoved.

The trio was again in a difficult situation. At this time, Lin Weiyin suddenly discovered an important clue: the body of the giant centipede did not seem to be entirely composed of thick armor. Her eyes widened and she shouted, "Luo Zhengding! Jiang Lengyan! See! It has no thick armor on its belly! ”

Hearing Lin Weiyin's reminder, Luo Zhengding and Jiang Lengyan also discovered the secret of the giant centipede. They immediately understood how to crack this formidable enemy: attacking the real body of the giant centipede - the heart. Luo Zhengding shouted: "We must attack its heart!" He brandished his spear and rushed at the giant centipede's belly again, trying to guide the giant centipede's heart to be exposed.

Jiang Lengyan followed, wielding her long sword and attacking her heart. Lin Weiyin also put away her previous hesitation and fear, and brandished her sword and rushed towards the head of the giant centipede. She slashed at the giant centipede's head, knocking it back for a short distance.

The three of them worked closely together and finally succeeded in exposing the giant centipede's heart. Luo Zhengding raised his spear again, Jiang Lengyan followed, and the two of them stabbed the giant centipede's heart together. The blow hit the target directly, and the giant centipede's body trembled violently.

Lin Weiyin didn't relax, she brandished her sword and rushed to the tail of the giant centipede, slashing hard. The blow directly severed one of the giant centipede's legs, causing it to twist its body in pain.

Luo Zhengding shouted: "Let's get out of this ghost place quickly!" ”
