Rainwater poured in from the entrance and exit of the nest along the main passage that sloped downward. The protagonist struggles to climb upwards, his limbs now soaked in water, and the mud on the soles of his feet makes it difficult for him to walk.

And the impact of the water is very strong, and the protagonist sees a worker ant next to him being swept away by the current, and soon disappears.

The protagonist himself has to do his best to resist the water that constantly hits him to ensure that he is not washed away.

Although he tries to elevate himself, his abdomen inevitably soaks in water, and the water pours into the air holes in his abdomen, causing the protagonist's body to cough and spasm.

After coughing up the water that had invaded the stomata, the protagonist had to force the air intake to close the air intake so as not to choke again.

Ants don't have lungs, but they have the ability to breathe, and they do it quite efficiently. Ants are able to perform rapid periodic external breathing at a rate of about once per second by compressing and dilating the small trachea in the head and chest.

When oxygen is inhaled into the ant's body through the stomata and enters the internal respiration mode: muscle movements control the contraction of the tracheal system, which then diffuses into the tissue cells.

Moreover, the protagonist discovers that ants have the same respiratory function as humans, with spontaneous breathing controlled by the pons, medulla, and spinal cord (spontaneous breathing has its own rhythm and is not controlled by consciousness like the autonomic cells of the heart), and voluntary breathing is controlled by the brain's consciousness.

It is the ability to breathe at will, controlled, that the protagonist is able to close his stomata and avoid drowning.

Experienced people know that due to the buoyancy of the water and the impact of the current, it is very laborious to soak in the water. It also took a lot of effort for the protagonist to climb to the ground from the muddy main passageway.

Once on the ground, the protagonist looks around and finally understands why tonight's flood is so ferocious - it's all self-inflicted.

During the day, the protagonist directs the workers to build a fortress, which is basically a circular enclosed earthen embankment, which encloses the entrance and exit of the nest of "Dongyang Castle" in the middle.

The entrance to the nest of Dongyang Castle was originally located on a high ground, at the top of a small mound, and when it rained heavily, the rainwater would flow down with the terrain, and very little water would pour in from the entrance.

And after the protagonist ordered the construction of earthen embankments during the day today, these earthen embankments did not consider the drainage design at all, just like its name, the earthen embankment faithfully fulfilled the function of the embankment when it rained heavily, blocking all the rainwater and enclosing the fortress.

A large amount of rainwater with nowhere to go can only be collected in low-lying places in the earthen embankment, and after the soil on the ground has absorbed the water, it constantly seeps water from the passage and wall of the nest, soaking most of the upper layer of the nest.

And that's not the main hazard.

As the small pools of water that had accumulated slowly coalesced into large pools, the water level was getting higher and higher, and some of the water had reached the entrance and exit of the nest, and then poured into the only exit.

If it weren't for the fact that the protagonist crashed into an earthen embankment during the experiment, the water broke through a small gap in the crack of the earthen embankment, and it continued to flow out, barely slowing down the speed of the water level rising, but I am afraid that the damage in "Dongyang City" would be a little worse.

The protagonist looks up at the sky, the dark clouds are very low, and the sky is dark, without a trace of moonlight and starlight.

The rain shows no signs of stopping, and the bean-sized droplets are dripping around, each big enough for the protagonist to swim in.

The water in the earthen embankment is still rising steadily, and more floodwaters are pouring into the entrance and exit of the nest every minute.

The protagonist knows that if he doesn't quickly dig a few more drains into the earthen embankment, the flood will only get worse, and many of the facilities on the upper levels of the nest, such as the mealworm farm, will bear the brunt of the damage.

The protagonist struggles to climb to the top of the earthen embankment in a slightly dry place, constantly adjusting his breathing to avoid choking.

From time to time, a drop of rain will fall on or around the protagonist, and although it does not cause damage, it repeatedly smashes him into the air.

This kind of rain drop attack from the sky is unguardable, if it is not for the protagonist's strength enough, the character is not bad, replaced by ordinary ants, in this weather is the end of nine deaths, once wrapped in a certain raindrop, or thrown into a pool, it is difficult to rely on your own ability to get out of trouble.

The protagonist is not afraid of this, he finally climbs to the top of the earthen embankment step by step, and then excavates the "ant concrete" that has been slightly soft after being soaked in rainwater.

After half a busy night, five drainage outlets were dug, and the rainwater accumulated in the earthen embankment finally showed no signs of rising.

As the rain gradually subsides, the protagonist finally relaxes and casually washes the mud off his body, and the protagonist returns to the dormitory in the city and falls asleep.

By dawn the next day, the rain had completely stopped, and the sun had covered the ground again.

When the protagonist wakes up, he has a bunch of headaches waiting for him to deal with.

The secretary reported that a number of worker ants and soldier ants died in the flood last night; Several mealworm farms on the upper layer of the nest are heavily flooded; The nest chambers of flies such as Xiaoqing are also flooded.

The protagonist asks the secretary to take charge of the aftermath immediately, and carry the dead ants out of the burrow as soon as possible to avoid the plague. Light small fires around the nest and dry the walls and floors of the nest. Mealworm farms and fly nests should also be repaired and counted as soon as possible.

After doing this, the protagonist summons Rambo to come to the surface with the worker ants who participated in the construction of the earthen embankment yesterday.

As a result of last night's flooding and the destruction of several earthen embankments to relieve the flood, the fortress that had been newly built yesterday had been completely unrecognizable: many of the embankments had collapsed, others had been soaked and destroyed, and large sections of the trenches had been filled with sediment from the flowing water.

Basically, most of the construction results yesterday were lost. The protagonist asks Rambo to lead the worker ants to clean up the ruins and then rebuild the fortress.

This time, the general design of the fortress remained the same, but sixteen drains were dug at the bottom of the earthen embankment, each with two soldiers passing side by side, so that rainwater could drain down the drains into the trenches.

The inner walls of the trenches and the outer walls of the earthen embankments were reinforced with rubble. A number of drainage channels were dug around the perimeter of the trench to lead to the low-lying areas, so that rainwater would not accumulate in the trench and could not be drained away, and eventually backfill the fortress.

After arranging the construction plan, it was time for the daily routine attack of the Parasitic Ant Legion.

The protagonist was tired last night, and he fell asleep very late, and he got up early this morning to deal with the aftermath, and he felt extremely tired at this time.

So the protagonist let Roll serve as the commander and lead twenty squads to the south to intercept the enemy forces south of the salt mine and protect the normal production in the salt mine area.
