7. The concept of purifier
After the whole class, Su Liu understood a basic concept, which is the core key for a purifier to carry out purification - to fully understand the initial appearance of the infected object.
In today's world, due to the infection of the "strange factor", most plants have mutated, lost their original appearance and characteristics, and turned into various unexpected violent forms.
If the purifier wants to purify it, he must first know the original appearance of the infected body, and then purify it in sections according to its characteristics.
In addition, the purifier has another responsibility, which is to assist the Ministry of Agriculture in planting and breeding activities, which also requires freshmen to be familiar with the breeding and planting plans of various animals and plants.
Even if you cannot pass the purifier test after graduation, you can at least become a grower and work in the breeding and planting industry in the future.
Su Liu didn't want to be arrogant, but this happened to be within her area.
Before falling to his death and coming to this strange world, Su Liu was an orphan.
The orphanage is located in the suburbs, where there is an agricultural experimental base that specializes in breeding activities, as well as research and cultivation of crops and medicinal plants.
Whenever the base is too busy, the director will take these orphans to do odd jobs and help with farming and breeding in exchange for some food, vegetables, meat, etc.
Later, Su Liu skipped grades again and again and was admitted to the city's Agricultural College at the age of 14. He systematically studied knowledge related to various crops and gained rich practical experience.
So it is no exaggeration to say that Su Liu, who was only 16 years old before traveling through time, had at least 10 years of experience in agricultural-related activities.
Su Liu spent half an hour going through all the textbooks, which basically contained popular science information about common animals and plants, knowledge related to agricultural planting, poultry and livestock breeding plans, etc.
It was incredibly simple for her.
At noon, Yan Ziyan from the next dormitory took her to the cafeteria.
Maha has several cafeterias. The cafeteria closest to the Department of Planting Teaching Building is a huge circular building with seven or eight floors. You need to swipe your card to enter.
Yan Ziyan pointed at the epaulettes on Su Liu's uniform.
"This shoulder badge is also your core pass to the school. It contains all your information, and you can use it anywhere you are authorized. Also, the school issues 30 meal tickets every month, which can be used for all three meals that day."
Su Liu swiped his card to go in and saw some people going up to the second and third floors.
"What's going on upstairs?"
"They're all cafeterias, but the higher the floor, the better the food." Yan Ziyan took Su Liu to the window and said, "We freshmen can only eat in the cafeteria on the first floor. We can't go upstairs."
Su Liu glanced at the window. The food was really not good. It was cooked like slop and didn't smell very good.
But there is no choice, everyone’s meal portion is the same, and you can’t even eat an extra spoonful.
The lunch on the first floor was indeed very simple, with steamed buns and corn paste as the staple food, and side dishes being salad lettuce and a fried starch sausage.
Su Liu didn't feel disgusted at all and even licked the plate clean.
The entire universe is affected by strange factors, and animals and plants may be infected and mutated at any time.
Therefore, planting and breeding are no longer a means for farmers to make a living. Instead, they are strictly controlled by the agricultural department and military purification divisions.
Therefore, supplies are very scarce, and even if many planets have large areas of wasteland, they cannot be put into use.
In addition, the current universe is seriously polluted, and pure natural food is in short supply. The better the quality of vegetables, fruits, meat, eggs and poultry, the higher the price and the less supply.
In the past, on K-72, fresh fruits and vegetables were scarce and expensive, and the varieties were very limited. Even the watermelons and oranges that Su Liu often ate in the orphanage were not available.
Yan Ziyan licked the plate clean and exclaimed in amazement, still feeling unsatisfied.
"From the third floor onwards, meat, eggs and poultry are basically supplied every day. I really hope that I can get into the top few dozen of the Planting Department as soon as possible and have the opportunity to eat upstairs."
Su Liu asked, "Do I need to pass an exam to go upstairs?"
"Of course," Yan Ziyan explained, counting on her fingers. "Freshmen like us can only eat on the first floor at first. Starting from the first exam, the top 100 students in each department can go to the second floor, the top 50 to the third floor, and the top 10 to the fourth floor."
All the food on these four floors is free. Above that is the cafeteria for faculty and staff, or for receiving healers, purifiers, etc.
Of course, you can also pay to go, but the price is not very friendly.
Every canteen has the same rules and the dishes are similar.
Su Liu got a general understanding of the cafeteria and felt that this school was indeed clearly divided into classes.
After two classes in the afternoon, Su Liu received a notice to go to school to help with chores.
Su Liu was in Class 3, which had a total of 30 students. They were all taken to the breeding city in a small school bus.
The breeding city is far away from the school and has an astonishingly large area. It is completely surrounded by a huge 50-meter-high wall, like a small city dedicated to raising poultry and livestock.
Countless soldiers armed with live ammunition patrolled back and forth, and fighter jets were on standby in the sky, which showed how powerful the military force deployed was.
After all, no one knows when and how the strange factor will infect animals and plants and drive them crazy.
Therefore, all agricultural areas must operate under military control so that any crisis can be nipped in the bud.
Before getting off the bus, the teacher assigned tasks.
"Your task today is to clean the pigsty. Remember, stay away from the pigs."
Before entering the breeding city, everyone must undergo a thorough body search to see if they are carrying any suspicious items.
It was an hour after they arrived at the destination. Su Liu was wearing a thick white protective suit, with only his eyes exposed.
After receiving the cleaning tools, the group was dispersed to various areas and started cleaning.
There are hundreds of pigs in Area B where Su Liu is located. Not only do they have to clean the pig pens and troughs, but they also have to use water guns to shower the pigs from a distance.
These pigs were twice as big as the "pigs" Su Liu had in mind. They were so fat that their bellies were dragging on the ground.
The teacher on the bus said that when the strange factor swept the world hundreds of years ago, pigs were actually infected and became very scary monsters that ate people like lollipops.
Fortunately, there were purifiers who purified a few pigs at that time, thus preserving the "fire" and allowing humans to eat pork today.
Su Liu couldn't help but think, how painful would it be if he couldn't eat pork?
After staying there for only ten seconds, the alarm sounded overhead and someone scolded him.
"Those inside, don't linger!"
Su Liu came back to his senses and quickly continued to give the pig a bath.
I heard that in recent years, the probability of strange factors infecting animals and plants has skyrocketed, many breeding and planting areas have been destroyed, and the number of related deaths has exceeded 10,000.
This is also one of the reasons why purifiers are in high demand. Only purifiers can quickly restore species to their original state and save the situation in the early stages of infection.
It took six hours to finish cleaning. Su Liu was so tired that his back and waist ached, and he returned to the car with a smell of pig manure.
The other freshmen were equally exhausted, slumped in their seats and snoring.
Just as Su Liu was about to take a nap, several tanks roared past outside, and at the same time, fighter jets in the sky flew in the same direction.
What happened again?
The boy in the front seat looked at the information on the computer and suddenly screamed.
"Oh my god, an infected person has appeared in the bird zone!"
"Fuck, is this true?"
The car, which was originally filled with snoring, suddenly became boiling with fear growing and spreading wildly.
An emergency notification also popped up on Su Liu's ring interface, telling the freshmen not to approach the breeding city.
But what if you are already in the breeding city?
