A group of blue-glowing creatures crawled to the bottom of the plateau, mostly two to three meters long, covered with a chitinous exoskeleton, and a cephalothorax with a well-developed horseshoe-shaped dorsal carapace, with a scoop-shaped body that was roughly scoop-shaped, divided into three parts: cephalothorax, abdomen, and tail. There are 12 pairs of appendages under the body, and the tail is slender like a sharp sword.

They don't crawl very fast, but they are covered in thick shells, and before they get closer, the Han people above them cannot effectively damage them with their bows and arrows, so they can only watch them get closer and climb up the rock wall.

Zhao Xinghua called them the Great Beetle, and the underground Han people called them the Water Rock Tiger because of their sharp mouthparts that can crush hard rocks. If these things were allowed to climb up, they would be like tanks with their huge bodies and hard carapaces, and it would be difficult to kill them again. Their weakest part is in the abdomen, which is difficult to attack in normal times, only when they climb up the vertical stone wall, and the person above them uses a long rod to pick them off to the ground, and they fall down, and these creatures cannot turn over on their own with their short appendages.

Zhao Xinghua is also learning from the Han people around him, holding a long pole and pinning a water rock tiger that is about to climb up, he sees that the people around him can easily pry those things off, but in his hands it is impossible to do it, this one under him has been busy for a long time, the pole has been shortened, that is Zhao Xinghua initially accidentally inserted the pole directly into the mouth of this thing.

Seeing that the big beetle was crawling closer and closer, and was about to climb up in a few more steps, Zhao Xinghua became more and more anxious in his heart, and took the long pole in his hand and stabbed it down with all his might. Sure enough, the pole was a lot shorter, and in a few steps this thing was about to climb up, and the nearby Han people shouted at him, but Zhao Xinghua, who was busy making a mistake, couldn't understand what he was saying. At this moment, the expert in ancient Chinese, who was acting as a translator, ran over and shouted:

"Don't poke it in the center! Pry its feet! ”

"Which one?!"

Zhao Xinghua has the heart to cry at this time, this thing has 24 legs.

"Can be pry on one side!"

"Grass! I'm an idiot! ”

It's a pity that it's too late, the upper body of the water rock tiger under him has already climbed to the top of the stone wall, Zhao Xinghua threw away the wooden stick, pulled out the battle knife, and while the big insect was still only half of its body crawling on the stone wall, he quickly slashed out several knives one after another......

Suddenly, a blue liquid spilled on the rock.

At this time, the two Han people who ran to support were also stunned, and then the two ran to the side and forcefully inserted the long pole in their hands under the body of Shui Yanhu, and at the same time turned over the big insect trellis lying on the stone wall.

Zhao Xinghua swung six knives one after another at the moment when the big insect climbed onto the stone wall and his body had not yet fallen to the ground, each of which slashed at the joints of the upper limbs of the Laishui Rock Tiger, cutting off the three pairs of appendages in front of him. Although this thing has 12 pairs of appendages, when moving on land, it is attached to the forelimbs, and the hind limbs are patchy swimming limbs, which only play an auxiliary role when moving on land.

Although Zhao Xinghua only cut off the first three pairs of appendages, he made the most powerful limbs when the strange insects moved.

"This is a prehistoric horseshoe crab! It was a creature of the same period as the trilobite, but I didn't expect it to exist on the earth now! ”

A newcomer biologist ran close and suddenly shouted in surprise.

"Leave it alone! There's more and more of this stuff below! ”

Zhao Xinghua found the trick this time, as long as he used a long rod to stab off the appendages attached to the side of the rock by the prehistoric horseshoe crab, this thing like a big beetle would lose its balance and fall down.

There are about a few hundred of these prehistoric horseshoe crabs around the small plateau, and although the people on the stone wall can stab them without much effort, they don't always let these big insects fall to the ground on their backs, and many times they climb up again after falling, endlessly repeating the process of going up and falling.

After Zhao Xinghua got started, the efficiency was much faster than ordinary people, almost all of them were successful at one time, and the area in charge was getting bigger and bigger, carrying a long pole to run back and forth on the stone wall, and he was very happy.

I was still wondering in my heart, where it was as dangerous as those Han people said, isn't it an easy thing.

Suddenly, a Han man who was in charge of watching shouted loudly again, holding two stones in his hand that he didn't know what material they were made of, "Bang! Nation! It made a crisp and loud sound.

Some of the Han people who took turns to rest also ran back to the top of the stone wall with various weapons.

When Zhao Xinghua was wondering, a young armed police soldier not far from his side shouted:

"Over there! Over there! Oh my God, what's that! ”

Zhao Xinghua looked in the direction he pointed, and a group of reddish-brown creatures appeared there, with an average length of about 3 meters, a pair of huge front chela, a pipa-shaped body, three side eyes on each side of the top of the head, a pair of middle eyes in the center of the back, and a sharp barb at the end of the tail that was curled upside down on the body, which was clearly the appearance of the surface scorpion magnified tens of thousands of times!

Due to the dim light, it is impossible to judge the number of giant scorpions coming ashore from the river, and they are not as capable of emitting light on their own as the prehistoric horseshoe crabs, but it can be inferred that these giant scorpions are not too small in number. Compared to their terrifying size, the previously clumsy horseshoe crab is adorable like a good baby.

Several giant scorpions came to the cliff face under the stone wall, and walked through a group of overturned horseshoe crabs, which were probably unable to whet their appetites, and none of these carnivorous arthropod insects attacked the horseshoe crabs around them.

A giant scorpion looked up at the top of the stone wall, and a swift arrow came into view. "Poof!" Suddenly, the arrow shot at the head of the giant scorpion erupted into a cloud of dazzling white light, and the bone armor attached to it burned violently.

Zhao Xinghua was surrounded by a lot of archers with bows and arrows, they aimed the bows and crossbows in their hands at the large giant scorpions below, and shot each arrow with full concentration, and a group of female Han people stood behind them to provide them with this special arrow. Zhao Xinghua saw that behind each arrow was a skin bag made of animal internal organs, which was wrapped in a liquid that he didn't know what it was. The women had to apply some powder to the arrows before handing them to the archers, and each movement was done with care.

"The sac contained a grease extracted from the grimace lizard, it was very viscous, had a low ignition point, had a high flame temperature, and burned for a long time, and when it hit the target, the sac burst, and the oil poured out would burn when it met the white phosphorus that had just been applied to the arrowhead. On the first day I came up, I studied this arrow, and the design was very simple and effective. ”

Xie Yunhao appeared beside Zhao Xinghua and said.

Many of the giant scorpions had been shot at different parts of their bodies with crossbows, and like other arthropods, they were so resilient that they desperately crawled up the cliff to the stone wall above them, trying to crush the creatures that hurt them.

The original method of dealing with prehistoric horseshoe crabs has lost its effectiveness, and each giant scorpion has a pair of huge claws, like two large pincers, that can easily crush anything in front of them.

With a vertical distance of ten meters, these prehistoric giant scorpions, which are more than three meters long, crawled in front of them in a few clicks.

"What to do?!"
