The first two abilities, one is not practical enough, and the other is not very useful, so Lin Fan considered the last one.

Clever!

At this moment, it is unlikely that you want to use the bald man to trick him into a stronger ability. That guy is a reckless man. The moment he sees him, he will most likely be in a spring.

Therefore, he could only consider whether he could use his teleportation ability to kill the bald man, such as falling from a high altitude.

"Falling at high altitudes has a huge problem, air resistance and the density of the falling object..."

"On the earth, limited by air resistance, the maximum free fall speed of ordinary people is about 50m/s..."

"Even if this fall speed falls from a height of 10,000 meters, even ordinary people may survive safely under the action of buffering props, let alone bald men with bulletproof muscles..."

"In addition, will the air resistance coefficient on the game island be consistent with the earth?!"

"However, the bald man's superpower is that the indestructible King Kong. His body density should be larger, with a small body size and a high density. When the gravity acceleration remains unchanged, the greater the descent speed should be..."

Lin Fan actually has a little unclear, that is, the bald man's bulletproof ability is whether it is a skin or a muscle. The density produced by these two effects is different.

"We also need to consider the transformation of that guy. His five-meter-high body shape is definitely not low, but it will slow down his descent..."

Lin Fan carefully considered it and deduced it from multiple angles. He found that even if he used his teleportation ability to pull the bald man to a height of 10,000 meters, he would probably not fall to death.

Of course, all this is based on the fact that the environment of the game island is exactly the same as that of the earth.

"Is that true? Just experiment!"

Lin Fan let out a breath and appeared in the hiding room with Hermione.

Take off her eye mask and say seriously: "Hermione, you hide in the closet and wait for me to come back..."

"good!"

After experiencing the fact that Lin Fan did not abandon him, Hermione had become brainless in trusting him.

Even if she was deceived by Lin Fan and eventually died, she would be willing.

She trusted so much that Lin Fan prepared the persuasion content in advance was useless.

Without much ink trace, Lin Fan quickly activated his teleportation ability and appeared in a high altitude at the edge of the poison circle.

Without any measures, he just landed straight down. However, at the moment of falling, Lin Fan threw down a rifle bullet prepared in advance and a pistol bullet.

In mid-air, he couldn't determine how fast he landed. After all, he was not a paratrooper who often jumped.

Therefore, he can only use two bullets with different density and volume as reference objects to calculate.

"Assuming that the relative velocity v in dt remains unchanged, the mass effect of the object surface is equal to the air mass, so the air mass acting in dt is m=ρSvdt, Ek=1/2mv^2=1/2ρSv^3dt, F=Ek/s=Ek/vdt=1/2ρSv^2. Considering that the effective action coefficient is C, then F=(1/2)CρSV^2..."

Lin Fan shook his head, "No, there is no need to do this, I'm considered complicated. I don't need to consider the kinetic energy of the falling object now, I just need to consider the speed of descent..."

Just calculating the descent speed became much easier. In just a few seconds, Lin Fan came to the conclusion.

According to his calculations, the final free fall speed of the pistol bullet will be fixed at 45m/s, while the free fall speed of the rifle bullet will be fixed at 75m/s.

The final speed of the two bullets falling was exactly one faster than him and the other slower than him. As long as this is determined, the air resistance issue is certainly consistent with the air resistance on the earth.

If the experiment is successful, it means that using teleportation ability to pull the bald man to a high altitude and fall, it will not cause fatal damage to him!

"My weight is 64kg. Assuming gravity is mg and resistance is f=v/2, there is already ma=mg-f, that is, m(dv/dt)=mg-v/2. The variables are separated and calculated separately. Assuming v=50m/s, g=9.8m/s^2, substituting the formula, we can get m≈79m, t≈5.6s."

"Achieving the maximum landing speed in about 5.6 seconds..."

Lin Fan did not calculate the maximum landing speed time for the bullet to reach, mainly because it was too cumbersome and time was limited.

It depends on the maximum speed he lands himself.

"1 second!"

"2 seconds!"

“…”

"5.6 seconds!"

As time counted silently, Lin Fan's attention was always on the two bullets.

The result was the same as he imagined that the pistol bullet landed at a lower speed than him, and it was landing above his body, and the rifle bullet landed at a higher speed than him, and it had already fallen to a position more than a hundred meters lower than him.

"It is about 140 meters away from the rifle bullet, which is close to the calculation results. After the experiment, the air resistance coefficient of the game island and the gravity situation are almost the same as that of the earth!"

After reaching the conclusion, Lin Fan did not continue to land, started his instant movement and returned to the building where Hermione was hiding.

[What did Lin Fan just do?!]

[Does he want to commit suicide?!]

[Suddenly a man appeared in the air and threw two more bullets. He wanted to know if the bullet could kill someone if it hit him from a high altitude?]

Lin Fan's calculations were basically silently reciting mental arithmetics, and they did not read them out, and most netizens did not understand them.

Only physics professors who are keen on numbers can have some understanding of it. Taking out paper money will make a calculation.

[He is doing some kind of free fall experiment!]

[I just calculated using calculus. He calculated the maximum drop of the human body, pistol bullets, rifle bullets free fall, and the maximum drop speed takes time...]

[Uh, can you say it simpler upstairs?!]

[Oh, Lin Fan should be testing whether the air resistance and gravity on the island of the game are consistent with the earth!]

[Damn, is it so strong? What is the result he measured?!]

[The result is that the air resistance on the game island, and the gravity is almost consistent with the earth!]

...

Experimental Middle School.

In Class 2 and 3, all members of the class except Lin Fan gathered together to watch Lin Fan’s live broadcast.

When he saw this scene, Teacher Wang was stunned, "You still teach these things in physics class?!"

All the students in the audience were also confused, "No, the physics class is about what v= what, t= what, g=9.8. All calculations are performed after eliminating air resistance..."

Teacher Wang turned his head and looked at the physics teacher, "You taught Lin Fan these things?"

The physics teacher is also very innocent, "No, he is in his second year of high school, where can I teach this thing..."

However, he pondered for two seconds and recalled: "I have brought the advanced mathematics textbooks related to calculus before..."

"What are you doing with this thing?!" Teacher Wang looked troubled. The thing he hated most when he was in college was that someone brought him here when he was in high school.

"I graduated from Nanqing Normal University with a bachelor's degree, but I am still taking the postgraduate entrance examination in private and studying for a master's degree from my alma mater, so I bring myself to study..."

The physics teacher was shocked, "Can Lin Fan learn it after flipping through it for a few random times?!"

Hearing this, Lao Wang's mouth twitched.
