"The ecosystem is a very delicate chain, and any deviation at any point will lead to a very wide range of changes in the whole chain. ”

"Fish migrating early and competing with the native fauna in the Silent River for bait will cause some of the hungry creatures to flee to the school grounds to feed, and if there are no fish migrating in the early spring, the animals in the Silent Forest will inevitably expand their predation range and inevitably harass the school's control. ”

"In addition, the rays are very ferocious creatures, and their encounters with different creatures on both sides of the Silent Forest during their migration can effectively reduce certain 'uncontrollable risk factors' in the forest, which is very effective in keeping the entire forest calm and stable. ”

"The above three points will have a very direct impact on the safety of the school and even the town of Beta. ”

"The destruction of the biological chain also means the death of a large number of living beings - including but not limited to starvation, competition for living space, decreased oxygen supply in the lake, etc. - death will bring a large number of dead bodies, and dead corpses will cause yin energy to rise. The only thing these carcasses will attract other than scavengers is the forest cleaners, known as corpse-eating beetles. ”

"The proliferation of corpse-eating beetles will affect the number of small animals that depend on this bug. ”

"Like rats. ”

"According to what we know so far, there are a large number of unexplained rats in many areas of First University, including Jiuyou University, and the University Working Committee has issued a notice calling on students who are able to help deal with these annoying little things. ”

"To sum up, the biggest impact of the resurgence of silence on First University is campus safety. ”

Speaking of this in one breath, Xiao Xiao seemed to be a little tired, stopped, and rested for a while.

"Very good, very good!" Lao Yao did not spare his applause at all, clapped his hands again and again, and praised Xiao Xiao's answer: "This answer is very comprehensive...... I can't say much more. Then, reward Xiao Xiao with one credit, everyone has no opinion!"

A sparse response rang out in the classroom.

It's all their own classmates, and there is only one credit, and people with broken brains will stand up and say that they have opinions.

The professor nodded with satisfaction, stuffed the pipe into his mouth again, and puffed out a large puff of smoke: "Since Xiao Xiao has already said what I plan to say......

Before he could finish his sentence, he came to an abrupt end.

Zheng Qing knew the reason why Lao Yao had stopped talking—in fact, everyone in the classroom knew—because Dr. Xiao, who had just received a credit award, interrupted Lao Yao in a very loud voice: "I haven't finished talking yet!"

The young public student tugged at the corner of Xiao Xiao's robe with a nervous face, and motioned for him to shut up and sit down first.

I've never seen such a stunned child, obviously he has already received a credit award, and he is still standing there, what are you doing with your mouth!

Zhang Jixin and Xin Fatzi, who were sitting in front of Zheng Qing and Xiao Xiao, straightened their bodies together, raised their heads and chests, as if they wanted to use their broad shoulders and huge heads to cover some nerd behind them who didn't know the depths - but obviously, their efforts had little effect. Not only could they not cover Xiao Xiao's figure, but they also couldn't hide the strange eyes cast in front of them.

Surprised, surprised, thoughtful, mocking, etc., etc., etc., the variety of eyes is dizzying.

"Not finished yet?" On the podium, Lao Yao repeated the last sentence Xiao Xiao said.

"I'm not done yet. Xiao Xiao pursed her lips and lifted her glasses, as if she had made up her mind.

Lao Yao changed his posture, picked up the teacup, took a big sip of tea, and then raised his head to look at Xiao Xiao again. Perhaps because the tea was a little cold, his expression seemed a little strange.

But he didn't order Xiao Xiao to sit down after all.

"What else do you mean?" the professor's tone, though still very gentle, was noticeably more cautious than before, "Tell me about it. ”

"The early return of silence means that schools of rays will not encounter sniper attacks from the flocks on both sides of the river as they pass through the middle and lower reaches of the Silent River...... This also means that there will be plenty of fresh food to be sent deep into the Silent Forest. ”

"While neither the school nor the Wizarding Union has ever known what is going on in the depths of the Silent Forest, we can surmise from previous news footage that many very horrible creatures must have been suppressed there. Every year, the silent return of fish is feeding those creatures...... This year, however, the amount of food is significantly higher. ”

"A well-fed monster, and a hungry prostrated monster, the combat effectiveness is obviously not on the same level. ”

At this point, Dr. Xiao finally closed his mouth contentedly and sat down.

The young student silently turned his head and carefully looked at the doctor's round face, which was not too big or small—the boy said that he was stunned, but he also understood what it meant to point to the end;

What happened in the depths of the Silent Forest was something that a little wizard in his first year could casually put his beak?

That kind of thing, like a 'black prison' where demons are imprisoned, like a 'relevant department' that administers forbidden spells, can only exist between small talk and rumors with everyone—even if there is reliable evidence, it cannot be talked about in public.

It is not conducive to the health and stability of society.

At the front of the classroom, Professor Yao held a teacup and paced back and forth on the not very wide podium, and finally nodded with a smile: "Hmm, Xiao Xiao's guess is also very interesting...... In short, as he said, this year's return to silence will have an impact on the safety situation in schools to some extent. ”

"It has mainly had a very serious impact on the ecosystem of the entire island of Phuket. For the past two weeks, we old fellows have been looking at just how bad the situation is along the Silent River. Because the river also runs through some secret gardens that are not big or small, the time of the investigation is slightly longer than expected. ”

"But we're pretty much done with our troubles...... The rest is your trouble—the school council has been making a series of announcements lately, including dealing with rats, corpse-eating beetles, and other strange things that have run in from the Silent Forest. Each academy was assigned a task. ”

"As my student, I've applied you for a job catching rats – rats are much more normal than the spooky corpse-eating beetles, venomous red-chained snakes, eight-eyed spiders, five-legged monsters, and more. ”

"So, starting this week, everyone has to catch 100 rats a week and send them to the school committee. The school committee will issue a receipt note, and you will return the receipt at the regular meeting on the weekend. ”

"For those who complete the task, 10% of the counselors will be evaluated at the end of the term. ”

"I can't complete the task...... Well, think for yourselves. ”

The implication is that people who can't even catch a few mice should not expect high scores from the counselor's evaluation.
