The evolution of insect swarms from XNUMX million years ago

Chapter 62 Mad Dog Out of Cage
  The vocal organs of several second-generation pioneer females continuously emit sound waves of specific frequencies to stimulate the lateral lines of the leader's ancient jaw, causing them to follow closely behind the pioneer females.

The leader's ancient eel-shaped body can't swim faster than the pioneers and fearless soldiers supported by the water jet propulsion system and shield-scale exoskeleton. The army's forward speed is much slower than before.

Although after gene editing, the leader Ancient Jaw is extremely disgusted with creatures with blue copper-containing blood, so it will not attack soldiers, but this is not necessarily the case for other creatures.

In order to prevent the leader of the ancient jaws from going crazy and attacking other creatures, Lin Yi controlled the ordinary soldiers on both sides to scatter around to clear out the nearby creatures, and brought the corpses directly back to the floating mother nest for absorption.

Trilobites, Sakaban soft-shell turtles, Aranda soft-shell turtles, etc. are killed directly. When encountering big players such as Poseidon Helmet Shrimp, poison-injecting soldiers are sent out to kill them with the poison glands of stinging insects.

If you encounter big guys like Cornerstone, let the fearless soldiers take action and treat them like snails. In this way, the army marched all the way to the place where the traces of the straight spiral stone were found.

The position of the floating mother nest has been locked by the micronized spy. When the adult Helical Stone carried the prey back to the mother's nest, Lin Yi controlled the micronized spy to attach to the opponent's floating mother's nest, completely locking the opponent's position.

After a period of march, the figure of the larvae of Orthospermum appeared above the "fleet", scanning the field of vision of the pioneer mother with its developed compound eyes.

Bing Gao immediately stepped forward and killed him easily. Of course, this also means that the movements of the army are exposed in front of the Straight Spiral Stone Nest Group, giving the opponent time to prepare.

But just when Lin Yi thought that the other side would gather troops to fight, the micro-spy Hui saw a scene that left him speechless.

Several filter-feeding hornbills slowly came forward, with their tentacles attached to their mantles wide open. They seemed to swallow all the snail eggs floating in the water into their tentacles like baleen whales in later generations.

Immediately, the larvae and adults gathered towards the mother nest, worked together to push the huge main part of the floating mother nest, ran the water jet propulsion system at full power, and evacuated cleanly in the opposite direction.

Looking at the running process in front of him, which was more skillful than the surrender of the country, Lin Yi could only feel that black lines appeared on the heads of all individuals in his consciousness at the same time.

If the opponent chose to run away after seeing the figure of the fearless soldier, he would still understand. After all, the fearless soldier's body length is not inferior to that of the adult snail and its size far exceeds that the swarm of snails cannot defeat it.

But he hasn't seen the fearless soldier yet, but he has only found a few groups of ordinary soldiers. They are ready to run away with their families and their families regardless of the fact that the eggs have not hatched yet. It really makes him speechless.

Fortunately, the speed of the floating mother nest is not too fast. Under the continuous positioning of the micro-spy, the army is still steadily chasing the opponent's floating mother nest.

The distance between the two sides is getting closer and closer, and the last few adults of the Straight Spiral Stone Nest Group have discovered the group of soldiers that are following closely behind. As well as the huge figures of the fearless soldier and the pioneering mother.

Seeing this, countless adult straight horned stones broke away from the large army one after another, turned around and came to kill, as if they were preparing to rear up for the large army.

But Lin Yi discovered that among the group of corner stones that came, there were even figures of filter-eating corner stones. Their body size is even larger than that of the Heliconia - although their body shape like a toilet pusher really has nothing to do with the feeling of oppression.

Perhaps the opponent's troops were insufficient and they could only use filter-feeding corner stones to gather them. Lin Yi thought about controlling the soldiers to move forward to meet him. But he didn't underestimate the enemy at all and still went all out. The distance between the two sides is getting closer and closer. The soldiers in the front row and the horned stones in the front row are already facing each other. Both the compound eye and the naked eye can clearly see each other's figure, as well as the sharp sickle limbs and horny beak.

The battle begins. The Straw Horn Stone nest group still followed a familiar routine. The adult Straight Horn Stone waved its tentacles, and countless larvae broke away, shooting towards the group of soldiers ahead like torpedoes.

Lin Yi quickly responded. Bing Hao moved toward the group of snails, and his sickle limbs covered with thorns immediately tore the body of a larvae of snails into two halves.

Immediately, in front, the soldiers and fearless soldiers spread out to both sides, clearing a path.

At the same time, in the body of the pioneer mother, the signal directing the leader of the ancient jaws to follow suddenly stopped, and was replaced by a signal of another frequency - that was the signal representing the attack!
  The leader of the ancient jaw group immediately stared with its well-developed eyes like a mad dog, twisting its eel-shaped body and rushing forward.

They are extremely sensitive to the fishy smell of iron-containing blood. And Lin Yi deliberately tore the larva of Orthosperm into pieces, causing a large amount of blood to surge out. Combined with the sound waves, it further aroused the leader's desire to attack.

Perhaps it was the first time to see a conodont of the size of the leader's ancient jaw. The Orthogonal Stone Nest Group had not yet reacted, and still focused on the group of soldiers in front of them, turning a blind eye to these leader's ancient jaw.

It wasn't until the mouth of the leader's ancient mandible with saw blade-like conodonts bit into the body of a helical larvae and tore its body into pieces that they realized that the other party was an enemy rather than a friend. They spread out and faced each other. The leader of the ancient jaw group.

At the same time, the adults from behind also came forward one after another. Each of the adults from the Helical Stone stretched out their arms, hoping to make the leader of the ancient jaw group retreat in spite of the difficulties.

But how could the leader Ancient Jaw, who was aroused by the specific frequency sound waves and the iron-containing fresh blood smell, retreat and swing his body to kill the adult Orthogonal Stone in front of him.

Lin Yi's guess was good. The structure of the tentacles of the straight spiral horn stone was indeed not suitable for dealing with the slender leader's ancient jaw.

The sharp horny beak bit the body of a leader's ancient jaw in half, but the gush of bright red blood stimulated the group of leader's ancient jaws even more. They swung their bodies and swarmed in to eat, and soon the soft body of the horned stone body was eaten. His body was partially torn and bruised, and he lost his fighting ability.

Before the soldiers and the fearless soldiers could take action, the leader of the ancient jaw group, who was like a mad dog out of the cage, had killed many adults of the Ortholiths.

But at this moment, the opponent changed their tactics again - the remaining adult helical stones started running their water jet propulsion systems and swam to both sides.

The tentacles of some adult helicotites still have scars, and a trail of blood is drawn in the water, making the leader of the ancient jaws pursue them even more.

However, the high speed brought by the water-jet propulsion system easily got rid of the leading group of ancient jaws in the rear, allowing them to concentrate on killing the group of soldiers in the rear.

And those filter-feeding hornstones opened their tentacles like extra-large toilet spatulas, sucking them towards the group of leading ancient jaws gathered together - Lin Yi finally understood the other party's intention of pulling the filter-feeding hornstones to the front line. .
