The salt marsh has changed again, which the protagonist did not expect! The last time there was an abnormality on the side of the salt marsh, it led to a shortage of salt on the south bank of the entire Great River, which cannot be ignored by the protagonist!

According to the report relayed by the courier, the water level in the salt marshes near "Yancheng" has been gradually rising recently, which has not happened in autumn before. According to the reports of local residents in Yancheng, the salt marsh only rises during the spring and summer rainy seasons in previous years, and the increase is not so large.

The unusual rise in the water level makes the tumor worry that it will affect the collection of salt, although there is no shortage of salt in the protagonist's territory after a period of rush some time ago, but according to the agreement, "Yancheng" must continue to supply salt to the main and secondary nests of the big-headed ant kingdom, and the transportation teams of these nests are constantly coming, rushing to stock up on enough salt grains before winter.

If this problem is not handled well, the situation is reported to the king meeting of "Qingqiu City", and the protagonist is worried that the other party will take the opportunity to take back control of "Yancheng".

If it's just a rise in the water level, it's not an anomaly, it's an anomaly at best. According to the tumor, as the water level of the salt marsh rises, many scattered salt pools have been connected, and the tidal flats have been covered. The ants found that the water was unusually turbid, and on a cold morning, there was a billowing mist.

The tumor sent the worker ants to venture into the lake, which proved that the lake water was warm, but undrinkable, and the lake water not only had a salty taste, but also a strong sour and bitter taste compared to before.

This is still not the worst case, the worst case scenario is that as the lake rises, a huge monster also arrives and attacks the salt gathering team in the "Salt City".

These monsters all have huge bodies, each the size of a boulder. Moreover, their dark green carapace is extremely thick, and they are not afraid of ant sieges, and a pair of large clawed claws can easily catch the ants and clamp them in two, or stuff the poor ants into their huge hideous mouthparts and eat them.

These monsters are able to roam freely on land and in the water, and can be found anywhere in the salt marshes, hunting for ants that are collecting salt grains for food, and hiding in the water when ants gather. Although their sideways movement is ridiculous, they are definitely not slow, and they often move in groups, and a large number of worker ants have been lost to the monsters.

The total ant population of "Yancheng" is only two or three thousand, and the team brought by the tumor is only two hundred worker ants and a team of fifty soldier ants. Now, hundreds of worker ants have been damaged in the "Yancheng" area, and the tumor has brought the only Divine Angel King team to try to capture a smaller monster, and they have also returned with feathers - the big jaws of the soldier ants can't break the monster's defense!

The courier also sends the protagonist a packet of information, in fact, after listening to the courier's description, the protagonist has roughly guessed what these monsters are, and the packet confirms this - it is a group of crabs.

Crabs are a species of arthropods belonging to the subphylum Crustacea, the class Mollusc, and the subclass Eumollusc. Its body is protected by a hard shell and breathes through its gills. Taxonomicly, it is the same animal as shrimp, lobster, and hermit crab.

The vast majority of species of crabs live in the sea or near the sea, but some inhabit freshwater or land. Judging from the image information in the information packet, these crabs that "do evil" in the salt marshes are ordinary river crabs.

The river crab is also called "hairy crab", and its head and thorax are combined to form a square shape, with a hard texture and a dark blue back shell. There are two pairs of very sharp crab teeth on the side of the eye, and the surface of the chelicerae is covered with villi; The sides of the 4 pairs of feet are flat and long, and the abdominal limbs have degenerated.

River crab is one of the freshwater crabs, often burrowing in the mud bank of rivers, rivers and lakes and marshes, nocturnal activities, feeding on fish, shrimp, animal carcasses and grains, often migrating to the estuary of the sea every autumn to spawn, the second year of hatching of young crabs and then back to the river.

In the eyes of humans, especially for Chinese, river crab meat is tender and a favorite food. In particular, hairy crabs are precious freshwater products, which are delicious, nutritious, and have high economic value, and of course they are not cheap.

However, for ants, these creatures the size of human palms are out-and-out prehistoric monsters, the smallest female crabs, whose weight and volume are equivalent to hundreds or thousands of ants.

The protagonist is puzzled as to why these river crabs suddenly appear in the salt marshes. River crabs usually prefer a freshwater environment, but the salt marsh is salty and has a sour and bitter taste, so it is definitely not the environment that river crabs like.

In addition, this season, if the protagonist remembers correctly, happens to be the season when river crabs lay eggs. Humans like crabs the most in this season, the female crab has delicious crab roe in its belly, and the male crab also has crab paste. But why don't the crabs go to their spawning grounds during this season, but instead come to the salt marshes where they haven't been before?

In fact, what the protagonist doesn't know is that the salt marsh area was originally an intermittent hot spring.

The hot springs have erupted infrequently in recent years, but in the past, it was these hot springs that came from the ground that brought salt-rich water to the salt marshes. The water evaporated slowly, and was rarely replenished by hot springs, resulting in the current salt marsh full of salt crystals and sporadic water pools.

The hot spring eruption site is far away from "Yancheng", where the swamps are dense and the ants cannot survive, and it is a blind spot in the big-headed ant kingdom, and the big-headed ant kingdom does not know what is going on inside. At the edge of the salt marsh, near the "Salt City", there is a place where ants can approach and collect salt.

To the south of the salt marsh, there is a large lake, which is the natural boundary of the kingdom of big-headed ants, and it is from there that the river crabs come from. They have lived in the lake and on the south shore for generations, where they thrive.

Recently, the long-dormant hot springs suddenly ushered in a big gush, a large amount of hot spring water mixed with salt, alkali and sulfur flowed violently, not only connecting the salt marshes that was close to drying up into a new lake, but also connecting the south flow with the crab lake to the south.

It is the ants that like to build their nests in high places, and "Yancheng" has survived the flooding, and most of the salt marshes and the crab lake to the south have been connected into a gourd-shaped lake.

The river crabs that originally lived on the south shore of Crab Lake only lay eggs in closed lakes for many years, but in their genetic memory, there is still the imprint of going to the estuary of the river to spawn.

When they detect the salty water from the salt marshes, the female crabs that are spawning immediately set off for a more ideal spawning spot.

So there was the scene in the emergency report of the tumor! A large number of female crabs appear in the salt marshes, and these female crabs also need to forage, and the dense ants near the salt marshes become the best prey.
