The grasshopper is also called the grasshopper ant, which is a kind of ant, and the grasshopper on the first university campus is the size of a thumb and the grass is green, and the scientific name in the encyclopedia of the wizarding world is 'green grasshopper'.

Frogs love shade and coolness, fish dew and tree moss, and can be used in medicine to relieve heat poison and sores, and some alchemists will also refine it into certain metals to obtain specific magical effects.

Unlike the large swarms of ordinary ants, frogs usually move in families.

Each family consists of a female ant, three or five male ants, and more than a dozen young ants. From this point of view, frogs have a similar social structure to magical creatures such as werewolves, naga, and centaurs.

This magical insect is active all year round, hiding in burrows underground during the day, crawling to the ground in the evening, mixing saliva with clods of earth, piling up a special cylindrical ant hill with a height of inches: the 'moon viewing platform', and after the ant wall is repaired, these frogs will climb to the platform in order - generally speaking, the mother ant will stay in the middle of the platform, and the young ants will only stay at the edge of the platform - they will lie there silently, sucking the moonlight and the yin energy of the night.

Researchers of magical creatures have observed that when these frogs lie on their stomachs on the anthill, they will construct different patterns depending on the weather conditions and the surrounding environment, and these patterns often have many similarities to the basic talismans studied by wizards. The mystery of this period has not been completely solved to this day.

After daybreak, the frogs will discard the ant nests that they have worked hard to build overnight and dive back into the ground. Until the next evening, the ants will re-select an open and flat meadow to continue their protracted lunar viewing project.

This lawn on the shore of Linzhong Lake is the hardest hit area for frogs to watch the moon.

Every ten months, the school workers need to clean up the traces left by the frogs, and those students who violate the school rules and discipline on weekdays will be asked by the school staff to wave their heads and smash the moon viewing platforms.

The frogs work hard, and so do the students.

When Zheng Qing came to the lawn, he happened to hear a punished second-grade student complaining: "These frogs are so annoying, why can't they apply to the school, get a little medicine, and sprinkle them to clean up." You don't have to work so hard. ”

The public scholarship student couldn't help but curl the corners of his mouth - this second-year dude must be a newcomer, and his blatant lazy words will definitely be scolded by the old school worker.

Although he is also quite supportive of sprinkling medicine.

Sure enough, it didn't take long for the old man Hemingway's rough roar to sound in the lawn: "You bastards! Not even the wizards of the First University! The frogs are the bait of more than a dozen magical creatures in the lake, and they also help the hundreds of old trees near the lake to clean up the moss." Even the dirt they left behind was the favorite fertile soil of old Stendhal in the Botanical Garden. ”

"Is there a little common sense?!"

The second-year old man was obviously frightened by the roar of the old man Hemingway, his face turned pale, and he quickly explained tremblingly: "I just think that these frogs have left too many dirt platforms recently...... I heard from my classmates that in the past, there were only 3,500 earthen platforms here every month, and they could be cleaned once a week. Now there are more than 100 new ...... almost every day. I have to clean it up every three or five days. I feel that the ecology of the lake is a bit unbalanced. ”

The old man Hemingway leaned his head, held the felt hat on top of his head, squinted at the lawn in front of him and the calm lake not far away, and his face improved slightly.

"Lately, it's a bit much. The old man nodded: "But it has not yet reached the point of ecological imbalance, if there are signs of that aspect, the school will notify us...... To think of that, it's okay. ”

The last sentence seemed to be complimenting the old student, but the words were too vague, and the old student didn't know whether to show a little surprise or continue the previous panic. Several expressions tangled together made him look like he was constipated.

"Maybe it's spring?"

Zheng Qing happened to walk up to the old man, and couldn't help but interject and replied, "After the spring thunder sounded, aren't the insects all active?" ”

"Frogs are different. The old man Hemingway shook his head: "The frog is a moon-born magic insect, which breaks its coat at the beginning of the month, matures in the middle of the month to mate, and dies at the end of the month. There is no such seasonal concept as spring. They are active all year round, and in the middle of every month, when the moonlight is at its brightest, it is their spring. ”

"That's it. Zheng Qing scratched his chin and felt that he had gained a little more knowledge.

"My classmates discussed it and thought it was because of the guys in the lake. The second-year student couldn't help but speak again.

Zheng Qing glanced at him seriously, and always felt that there was a trace of portrait between him and Dr. Xiao. The old school worker snorted and did not comment on this new idea.

"Why?" Zheng Qing asked rhetorically.

The 'guys in the lake' are naturally the fish-people. But there is a difference between the fish-man and the frog worm, and even if the fish-man likes to use the sun-dried frog as a snack, it has nothing to do with the mass reproduction of the frog - on the contrary, because the fish-man is greedy, the number of frogs will decrease a lot.

"Because frogs like fish sauce. The old student looked at Zheng Qing in surprise, as if he was curious why he would ask such a strange question.

As if knowing Zheng Qing's confusion, the old man Hemingway kindly explained: "The so-called 'fish sauce' is an elegant name, but it is actually the feces of the fish people. ”

Zheng Qing was suddenly stunned.

A few days ago, the fish people marched and demonstrated, and threw a lot of dung on the lakeside. If frogs like 'fish sauce', it makes sense why they have proliferated abnormally lately.

After explaining, Old Man Hemingway finally reacted to a gossip guy standing on the lawn.

"Anyway, are you here to help clean the lawn?" the old man raised his eyebrows and squinted at the young student. The second-year guy next to him had a hopeful expression on his face.

"Not really. Zheng Qing couldn't help but smile - the old student immediately lowered his head in disappointment - and said to the old man Hemingway: "You handed me a note last night and asked me to come to you at noon today." ”

"Last night?" the old man squinted and scratched his head, apparently with a poor memory.

"It's the night patrol of Linzhong Lake on Saturday night, because I have other things to do, which may delay the patrol, so I applied for an adjustment of the mission before. Zheng Qing carefully added.

"Oh, that's it. Old man Hemingway stretched out his hand: "The application process over there of the school working committee is over, right?" ”

Zheng Qing nodded quickly.

"Well, let's clean up these frog anthills. The old man waved his hand and assigned Zheng Qing a new task: "Two choices, one is to see the seams and do it as you go, and by Saturday, you can do five hours of trivial tasks; ”

Zheng Qing looked at the range from 'here' to 'there' that the old man pointed to, and gasped.

He estimated that the 'mission area' was half the size of a football field.

"I choose the first one. He made his choice in frustration.

"I've got extra head here!" the sophomore greeted cheerfully.
