Being stared at by a monster as big as a building and as big as a mountain, the monster's eyes are about the same size as his own body, and this monster also has giant pincers and a big mouth that can kill instantly, the protagonist is immediately hit by a strong Surrounded by a sense of crisis.
Just when the protagonist stopped and the ants behind him also stopped, the simple-minded crab seemed to think that there was more food here, gave up its original position, and rushed forward without hesitation.
However, the way it rushed over was a bit different.
As the saying goes, crabs are "domineering". This crab is moving sideways, which is a way of movement determined by its body structure.
The crab's full legs grow on both sides of the body. The first pair of chelipeds are tools for digging holes or weapons for defense and offense, and do not participate in movement. The remaining four pairs are used for walking, called steps. Each step is composed of seven joints, and the joints can only move up and down.
Since the width of the thorax of most crabs is greater than their length, they can only crawl with one side of their legs bent, grabbing the ground with their toes, and the other side of their legs extending outward. When their toes reach the ground in the distance, they start crawling. Contraction, and the originally bent foot immediately straightens, pushing the body to the opposite side.
In the crab's body, when it moves, each limb has two upper and lower bony eyes (the bony eyes are where the muscle bundles pass through), that is, the two bundles of muscles are connected to it. Moreover, the bending direction of the joints at the base of its limbs is in the dorsal and ventral direction, so when the muscles contract, the limbs are moved in the dorsal and ventral direction, and the crab moves laterally.
Since the lengths of these pairs of legs are different, the crab actually moves sideways and 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. Over the long time since the formation of the Earth, the magnetic north and south poles have reversed many times. The reversal of the geomagnetic poles disorients many organisms and even causes extinction. The crab is an ancient migratory animal. Its inner ear has small directional magnets and is very sensitive to geomagnetism. Due to the reversal of the geomagnetic field, the small magnets in the crab's body lose their original orientation. In order to survive the reversal of the geomagnetic field, crabs with less developed brains adopted the approach of "keeping the same in response to all changes" and simply evolved to move sideways without moving forward or backward.
However, not all crabs are allowed to run amok. For example, long-armed monk crabs that live in groups on the beach can run forward. Many spider crabs that live in seaweed can also climb vertically on the seaweed.
Now, this giant river crab predator is quickly approaching the protagonist in this seemingly funny, but seemingly slow, and fast way. The threat contained in its huge body is far greater than the mantis the protagonist faced before.
The river crab targets the protagonist's group of ants and quickly approaches sideways and forward, temporarily closing a bunch of crab claws in front of it. But with just a moment's pause, the pair of crab claws stained with ant blood, tissue fluid and debris can turn into deadly weapons.
Alarm bells rang in the protagonist's heart. This river crab looked slow, but due to its huge body, it could cover a large area, completely blocking the way for the ants to escape back to their nest.
The ants seem agile, but it is difficult to escape the attack range of the giant claws of the river crab in a very short time.
If you go forward, you may have a narrow escape, but if you escape, you can enter the temporarily safe underground. It was impossible to retreat. There were dozens of river crabs in the rear looking for food in separate pieces. Such a large group of ants also attracted them to move here. The ants who followed the protagonist to escape were already in a predicament of being attacked from both sides.
The protagonist's heart was filled with excitement and he rushed forward. The ants behind him all followed his voice and scent signals, and they all started to move at this moment, moving forward like rushing water.
The huge river crab stopped, adjusted its direction, and faced the stream of ants rushing towards it, as if it was seeing countless feasts delivered to its door.
The protagonist has no plans to use "God Descends to Earth" for the time being. He sees a glimmer of hope. If he can escape based on his current state, he has no intention of entering the invincible mode with serious sequelae.
At this moment, the protagonist's body is filled with adrenaline. He feels that everything around him is slowing down. He can clearly see the giant claws that the river crab is slowly raising. The jaws are slowly opening in a terrifying arc. The one on the left The crab claws are already aimed at him and are approaching, and the crab claws on the right are also ready to hit him at any time. These are a pair of extremely dangerous weapons.
The protagonist can feel that the breathing in his orifices is accelerating, frequently swallowing air, and the heartbeat and blood flow are also accelerating, which provides more energy for physical activities, making the protagonist feel sharper and his athletic ability is greatly improved.
The moment the crab claws pierced him, the protagonist exerted force on his back limbs and jumped to the right, narrowly avoiding the attack of the crab claws with a jump rarely used by ants.
What follows closely is the finishing blow from the right claw of the river crab. This is the instinctive attack method of the river crab. One to the left, one to the right, one in front and one behind. It is difficult for any prey to escape the coordinated attack of the two crab claws.
But the protagonist did it, and his brain was extremely clear. He had studied the movement and attack methods of crabs in the tree before, and figured out the rules. At this moment, he had already determined the trajectory of the crab's right claw. As soon as he landed on the ground, he exerted force again, and felt a slight pain in his rear limbs. It was a strain caused by excessive muscle output due to continuous output.
But the protagonist didn't care so much and continued running wildly, avoiding the attack from the right pincer.
At this time, he had already run into the belly of the river crab, and with his compound eyes he could see the huge umbilicus of the female crab above his head. After passing here, the river crab will not be able to attack itself with its claws unless it turns around hard. This is the river crab's attack blind spot, and it is also the only way for the protagonist to survive.
Other ants follow, but many of them don't have the same luck or strength as the protagonist.
The river crab has a simple mind. He will not regret that he failed to kill the first ant in two attacks. For him, there is still a lot of food and many opportunities.
I saw its pair of pincers stabbing out alternately like lightning. Every time, almost an ant was caught, and it was quickly put into the mouth, chewed twice and swallowed.
The ants suffered heavy losses in this attack, but most of the ants still followed the protagonist closely, crawling through the belly of the giant river crab, and escaped into the unrecognizable nest that had been dug up before other crabs caught up behind them.
The last remaining ants on the ground also caused a fight between the river crabs.
As the river crabs slowly retreated, a bloody setting sun covered the messy "Salt City" ground, adding a bloody background to today's events.
