Stared at by a monster with a body as huge as a building and a mountain, the monster's eyes are about the same size as his own body, and this monster also has huge pincers and large mouths that can kill instantly, and the protagonist is immediately surrounded by a strong sense of crisis.

Just when the protagonist stopped, and the ants behind him also followed, the simple-minded crab, who seemed to think that there was more food here, gave up its original position, and rushed up immediately without hesitation.

It's just that the way it rushes over is a little different.

As the saying goes, a crab is "overbearing", and this crab is moving sideways, which is determined by its body structure.

The crab's full feet grow on the sides of its body. The first pair of chelicerae, which are burrowing tools or defensive and offensive weapons, do not participate in movement. The remaining four pairs are used for walking, called footsteps, and each foot is made up of seven segments, and the joints can only move up and down.

Because most crabs have a greater width than their length, they can only crawl with one foot bent and grasp the ground with their toes, and the other foot stretches outward, and when the toes reach the ground at a distance, they begin to contract, while the originally bent side of the foot immediately straightens out, pushing the body to the opposite side.

Whereas, in the crab's body, when it moves, each limb has two upper and lower bony eyes (the bony eye is where the muscle bundles pass through), that is, two bundles of muscles are connected to it. Moreover, the bending direction of the joints at the base of the limb is the dorsal and abdominal direction, so when the muscles contract, the limb is pulled to move in the dorsal and abdominal direction, and the crab moves laterally.

Since the length of these pairs of feet is different, the crab actually moves sideways forward.

There is also a theory that changes in the Earth's magnetic field shape the way crabs move.

Crabs rely on the geomagnetic field to determine direction. In the long years since the formation of the Earth, the north and south poles of the geomagnetic field have reversed many times. The inversion of the geomagnetic pole has left many organisms at a loss and even caused extinction. The crab is an ancient migratory animal that has small directional magnets in its inner ear and is very sensitive to geomagnetism. Due to the inversion of the geomagnetic field, the small magnet in the crab body loses its original orientation. In order to survive the inversion of the geomagnetic field, the crab, which is not fully developed, adopts the method of "adapting to all changes with the same", and simply evolves into a way of moving sideways instead of moving forward or backward.

However, not all crabs can only go on a rampage. For example, a colony of long-wristed monk crabs living on the beach can run forward. Many spider crabs that live in seaweed thickets can also climb vertically on the seaweed.

Now, the giant river crab predator is approaching the protagonist in this seemingly funny, but slow, but slow way, and the threat contained in the huge body is far greater than the mantis that the protagonist has faced before.

Targeting the protagonist's group of ants, the river crab quickly approaches sideways and forward, with a bunch of crab claws temporarily tucked in front of them. But it only takes a moment of pause for the pair of crab claws, stained with ant blood, tissue fluid, and wreckage, to turn into murder weapons.

The main character's heart is full of alarm bells, this river crab does not seem to be fast, but due to its huge body, it can cover a large area, completely blocking the way for the ants to escape back to the nest.

The ants seem to be agile, but it is difficult to escape the attack range of the river crab giant claw in a very short time.

In the past, it is possible to die for the rest of your life, but if you escape, you will be able to enter the underground for the time being. It is no longer possible to retreat, and there are more than a dozen river crabs in the back foraging in pieces, and such a large swarm of ants has also attracted them to move here. The ants who fled with the protagonist have fallen into the dilemma of being attacked on their backs.

As soon as the protagonist's heart is crossed, he rushes forward. The ants behind him all followed his voice and smell signals, and they also took action at this moment, moving forward like rushing water.

The huge river crab stopped, adjusted its direction, and faced the ant stream rushing towards it, as if it saw countless meals delivered to its door.

The protagonist doesn't plan to use "Celestial Descent" for the time being, he sees a glimmer of life, and if he can escape with his current state alone, he doesn't plan to enter that invincible mode with serious sequelae.

At this moment, the adrenaline in the protagonist's body is rushing, he feels that everything around him is slowing down, he can clearly see the giant claws that the river crab is slowly lifting, the jaws are slowly opening, opening a terrifying arc, the crab claw on the left has aimed at himself and is poking over, and the crab claw on the right is also ready to mend the knife at any time, this is a pair of extremely dangerous murder weapons.

The protagonist can feel his breathing in his bloads faster, swallowing air frequently, and his heartbeat and blood flow accelerating, which provides more energy for physical activity, making the protagonist feel more sensitive and athletic.

At the moment when the crab claws pierce him, the protagonist's back limbs exert force, and he jumps to the right front, narrowly avoiding the attack of the crab claws with a jump that is rarely used by ants.

Followed by the mending knife of the river crab's right pincer, which is the instinctive attack mode of the river crab, one left and one right, one front and one behind, it is difficult for the prey to avoid the coordinated attack of the two crab claws.

But the protagonist did it, his brain was extremely clear, and he had studied the movement and attack of crabs in the trees before, and found a pattern. At this moment, he had already judged the trajectory of the river crab's right pincer, and as soon as he landed, he exerted his strength again, and there was a slight pain in his back limbs, which was a strain when the muscles were continuously output and the force was too strong.

But the protagonist doesn't care so much and continues to run wildly, dodging the attack of the right pincer.

At this time, he had already run into the belly of the river crab, and his compound eyes could see the huge umbilicus of the female crab on the top of his head. After this, the river crab can't attack itself unless it turns hard, or its crab claws can't attack itself, this is the blind spot of the river crab's attack, and the only way for the protagonist to find a way out.

The other ants followed, but many of them didn't have the luck and strength of the protagonist.

The river crab is simple-minded, he will not regret that he failed to save the first ant after two attacks, for it, there is still a lot of food, and there are many opportunities.

I saw that its twin pincers stabbed out alternately like lightning, and each time it was almost caught by ants, and it was quickly put into its mouth, chewed twice, and swallowed.

The ants suffered heavy losses under this attack, but most of them followed the protagonist closely, burrowing through the belly of the giant crab and fleeing into the unrecognizable nest before the other crabs chased after them.

And the last remaining ants on the ground also caused a big fight between river crabs.

As the river crabs slowly retreated, a bloody remnant of the sun covered the messy ground of "Yancheng", adding a bloody background to today's events.
