What is the exciting plot of "How Steel Was Tempered"?

The wonderful plot of "How Steel Was Tempered" is:

The autumn rain slaps people in the face. Groups of dark clouds filled with rain moved slowly in the low altitude. In late autumn, all the leaves have fallen in the endless forest. The old elm tree stood gloomily, hiding its wrinkles under the brown moss. The ruthless autumn stripped away their gorgeous costumes, and they had no choice but to stand there naked and skinny.

The small station is hidden alone in the woods. A newly built roadbed stretches from the station's stone platform into the forest. The roadbed was surrounded by a crowd as dense as ants.

Obvious slime plopped under the boots. People on both sides of the roadbed were digging hard. The iron tools made a heavy impact, and the shovels clanked against the stones.

The rain was like sifting through a sieve, thin and dense, and it kept falling. The cold rain soaked into my clothes. The rain also washed away the fruits of people's labor, and mud dripped down the roadbed like thick porridge.

The soaked clothes were heavy and cold, but the people worked hard until it was completely dark before leaving the construction site.

The roadbed being built is getting longer and longer day by day, extending deeper into the dense forest.

Not far from the station, there is the empty frame of a stone house, standing there desolately. Everything inside that could be pried off, taken apart, or smashed had been looted long ago. The doors and windows turned into gaping holes; the furnace door turned into a black hole. The roof was also in tatters, with rafters exposed in many places.

The only thing that was not robbed was the concrete floors in the four rooms. Every night, four hundred people sleep on it wearing clothes soaked inside and out and splashed with mud. Everyone was wringing their clothes at the door, and dirty water flowed down.

They used the most unpleasant words to curse the bad weather and the mud everywhere. There was a thin layer of hay spread on the concrete floor, and they slept on it next to each other, using each other's body heat to keep each other warm. The clothes steamed, but never dried.

The rainwater seeped through the sacks covering the window openings and dripped onto the ground. The raindrops hit the remaining iron sheets on the roof like dense shotguns. Cold wind kept blowing in through the cracks in the broken door.

The kitchen is an old shed. In the morning, everyone had a quick snack here and then went to the construction site. Lunch consisted of a fatally dull vegetarian lentil soup and a pound and a half of bread that was almost as black as coal.
