Professor, your turtle!

Ji Fan said he wanted to try, but no one took his words seriously. Many students secretly glanced at the blackboard with the mentality of watching the excitement.

The physics teacher took a few steps back, signaling him to hurry up.

Ji Fan took a deep breath and raised the chalk to write. At first glance, the formula was simple and smooth, and it really seemed like that.

First simplify the pulley, then analyze the slope force diagram of the small slider, then analyze the force of the spring, and the energy conservation formula...

Step by step, he actually listed the same number of formulas as the unknown quantities.In other words, as long as the unknown quantity can be solved by peeling off the cocoon, this problem will be declared solved.

—Maybe not the smartest and fastest way, but definitely half done.

After listing the formulas, Ji Fan's hanging heart finally fell to the ground.He glanced to the side from the corner of his eye. The physics teacher's face was cloudy and uncertain, and his mouth was half-opened, which seemed a little unbelievable.

Ji Fan's eyes only stayed for a short moment, and then he refocused on the topic.

His speed of solving problems is not fast. When he wrote the last few steps, many academic masters who specialize in physics in the audience have already come up with the answer.They raised their heads and began to watch the problem-solving process on the blackboard.

Step by step, quite satisfactory.Although it is a stupid method, it has a solid theoretical foundation. Even with Zhao An's critical gaze, he couldn't find any obvious mistakes.

Ji Fan has always been serious and rarely makes calculation mistakes. Seeing this question, he will not be troubled.

"Okay, the idea is the same, let's go on." The physics teacher waved his hand with a dark face, "There is no need to write the rest."

There was no notification that the task was completed in his head.

Ji Fan snapped his fingers and broke half of the chalk—the so-called problem-solving is not just about having ideas. Only when he gets the correct answer can he truly prove that he is right and prove to the whole class that he can do it too!

He held the chalk tightly and whispered, "No, I..."

"what?"

Ji Fan turned to look at him, nervously but clearly said: "No, I want to finish it."

He rarely voiced his opinions publicly in class, let alone contradicting others.Not only the teacher, but also the students below were stunned, and the classroom was too quiet for a while.

The physics teacher pursed his lips and looked at him, as if looking at a freak.Ji Fan stood still and persisted in silence.

After a while, the teacher said impatiently, "Then hurry up."

"En." Ji Fan nodded, and continued to draft in the open space next to him, trying to figure out the final result.

Only he himself knew that after the experience just now, his palms were covered with fine sweat, and even his fingertips trembled slightly.

But he didn't regret it - the reward was 400 beans, how could he fall short because of the teacher's words?

Ji Fan was preoccupied with rewards, but he didn't notice the whispers that gradually sounded from below.

"Pfft, Guifan took the wrong medicine today?"

"I'll go. Look, he seems to have made it for real. Is it true?"

"The steps seem to be fine... Wait for a boss to verify."

"Wait for the big brother 1. I didn't write a pen myself because I was so busy watching the show."

"The answer I got is... wait for him to finish the calculation."

After writing the final "answer", Ji Fan took a step back.There was a sudden silence in the audience—the answer was correct and accurate.

Ding!When the reminder sounded that the reward had arrived, Ji Fan relaxed and couldn't help showing a hint of a smile.

He has always lived like a shadow, giving people the impression that he is always introverted and gloomy, but at this moment, he seems to have suddenly walked out of a dark corner.

Under the sunlight, the dimples around his lips were faintly visible, and the soft peach eyes were slightly curved, which reminded those who had ignored him that this was also a handsome and bright boy.

The girls around couldn't help but look a few more times, and then looked away a little embarrassedly.Seeing this, Zhao An's nose was almost crooked.

Ji Fan felt a little embarrassed after realizing it, and walked back to his seat quickly, only to hear Xu Haifan excitedly say: "Hey, did you see the face of 'baldy'? Hahaha, I laughed my head off."

The physics teacher coughed dryly: "Actually, this solution is the most basic. Students who have made mistakes can check the steps. Let's look at the advanced solution—" During the conversation, the topic was moved away from Ji Fan. .

Xu Haifan leaned over and whispered to Ji Fan, saying that the old bald man just couldn't show his face to praise others, after all, his face was slapped.

During the lecture, people in the front row turned their heads and looked around from time to time, as if they knew him for the first time.

In fact, Ji Fan's mind was no longer in the classroom.He was thinking about what to exchange for the 400 beans that fell from the sky.

However, Ji Fan did not receive another call from Fu Mingyuan for the whole day.

The villain on the screen was quiet and well-behaved, which made Ji Fan a little curious, what did Mr. Fu do today?

—Of course, except for that pot of carbide.

Back in the space at night, Ji Fan looked through the historical news, and it was very quiet inside, without any news or touch interaction.

Mr. Fu...it seems that he didn't play with his little turtle.He felt a little indescribably lost.

On the contrary, the "mysterious props" presented by the previous side missions have been distributed to the backpack, and the icon is so black that it is hard to see what it is.

Ji Fan clicked the icon curiously, only to hear a bang, and a large box fell out of thin air, hitting the center of the room.

He unpacked it and found that it was actually a group of large aquarium incubators.

The incubator is divided into several layers, which can respectively simulate different pressure states, covered with a light-shielding film, and perfectly realize any state from shallow sea to deep sea.

Is this... is there any animal to be raised?

A beep suddenly sounded.

[Trigger task: Large shrimp farmer (Level [-])]

[Remarks: Rescuing the endangered Antarctic krill is the duty of a biology lover! 】

[Task reward: Shrimp's favor (arthropod favorability max)]

Antarctic krill?Wait, what is this strange reward?

In the next second, the water gate in the "shallow sea area" of the incubator suddenly opened, and countless orange translucent shrimps swam out happily, with fluorescent dots on their heads, which shocked Ji Fan.

The fully automatic layered incubator is in a closed state, without any communication channel to the outside world, and it is unknown where these krills suddenly appeared.

Taking two steps back, Ji Fan slowly calmed down.

Antarctic krill, as the name suggests, lives in the low-temperature "peripheral ice region". It is an integral part of the Antarctic ecosystem and is responsible for converting the energy of phytoplankton into biological protein that can be eaten by fish.

They are also very beautiful.The whole body is light orange, and through the crystal clear shell, you can see the fluorescent green esophagus on the small head, with a sharp contrast in color.

Most importantly, they are delicious.The meat of extreme krill is sweet and delicious. It is only because of the high cost of fishing and the difficulty of preservation that it has not become the mainstream seafood on the human table.

Ji Fan is very interested in marine biology and has learned about these miraculous shrimps.

The protein content of krill is extremely high, and it reproduces extremely fast and has strong adaptability. The maximum living density can even reach [-] per cubic meter.

Some people have made statistics that the total mass of Antarctic krill may even be greater than the sum of all human beings on the earth, about more than 5 million tons.

However, Ji Fan frowned slightly. How could such a large number of creatures be on the verge of extinction?

Is there a system error?

A simple breeding manual is placed on the top of the incubator.

It states that March belongs to the krill spawning period.The task of the breeder is to manually open the internal water gate every day to let the fertilized shrimp eggs sink to the bottom of the deep sea simulation area.

This is also simulating the habits of Antarctic krill. They often lay eggs above the deep sea, and the shrimp eggs sink all the way until they reach a depth of 2000-3000 meters before they start to develop. for the best protection.

In the manual, there are a lot of little knowledge like this.However, Ji Fan searched through the entire book, but he still couldn’t figure out why the system said that Antarctic krill were on the verge of extinction—they could live, live, and feed well. To be fair, even if all human beings were extinct, they wouldn’t be able to turn to them!

Unless the entire Antarctic Ocean disappears.

Ji Fan couldn't figure it out, so he simply pushed the "mysterious item" to the corner and turned to check the mall.

The container in the 400 bean mall is unlocked, and the corresponding food, clothing and energy are placed.

Ji Fan took a cursory glance.Ski goggles, waterproof jackets, and liquefied gas tanks are useful, but the new food bar looks interesting.

——Yellow peaches in syrup, oranges in syrup, and canned grape peaches may be very suitable for Mr. Fu who is unhappy.

However, he can completely coax people by cooking, and the raw materials are very cheap, so there is really no need to squander Qin Xuedou to buy these luxuries.

The mall is much richer, but it is a bit flashy.

Ji Fan was slightly disappointed.

After thinking for a moment, he cautiously bought a bag of potatoes and dehydrated vegetables worth 300 beans, spending all the 400 reward points he just got.

——Since Mr. Fu has no doubts, Ji Fan decided to repeat the old trick and secretly cook a bowl of real curry in the middle of the night.

From experience, food is a magic weapon to stabilize mood.However, the curry with only canned corn and sausage is too outrageous. The soul of curry, of course, is potato cubes!

The first time is raw and the second time is cooked.That night, the Zzz icon floated above the electronic villain's head, symbolizing that Fu Mingyuan was fast asleep. Ji Fan held his breath and waited for a moment before quietly changing back into a human form.

Fortunately, the clothes hidden last night were still there, so Ji Fan put on thermal underwear and decided to make a quick decision - there are only 40 minutes left in the special time, which cannot be wasted.

The stove was cleaned up by Fu Mingyuan, together with the leftover dishes from last night, it saved Ji Fan a lot of effort.

The food was cooked quickly, with ingredients such as vegetables and potatoes added, the chowder curry was more delicious than last night, and even he couldn't help but sneak a small bowl of it.

5 minutes remaining.Turn off the fire, sneak back to the living room, take off your clothes and hide, and snap back into a turtle.

Ding, the time is back to zero, everything is just right.

Ji Fan lay on his stomach, vomited a bubble quietly, and his heart beat a little faster.

Maybe tomorrow, the other party will curl up his thin lips and say "delicious" with a smile.

In the darkness, he unconsciously smiled.
