Evolution from scratch with added points

There is a saying: After not seeing each other for a few days, Chen Jue found that he liked Teacher Wu's appearance and appearance more and more.

As for Wu Fang, her eyes lit up after seeing Chen Jue appear!

"We haven't seen each other for a few days. Have you gone for a hair transplant?" Wu Fang came over and said hello curiously and asked.

Because she found that Chen Jue, the unique talent brother whom she hadn't seen for a few days, was actually a little brighter than before.

Not only was his hair cut short, exposing his forehead, but even his previously faint scalp was gone.

He looked even more straight and upright, with his increasingly broad shoulders and strong upper body supporting the black and white sportswear on his body. His feet were steady and strong, and he was just strolling around with a bit of a model catwalk style.

Clean and refreshing, sunny and strong, although his appearance is ordinary, but with a bit of confidence and calmness on his face, he is a perfect 7-point handsome man!

Although he is not as handsome as a celebrity, at least some girls will turn around and look at him on the street.

"Hair transplant? That's not the case! The risks of hair transplant are not small, and there are also side effects of rejection. Recently, I went to bed early and got up early, and went to the hospital to prescribe some Chinese medicine. After taking it slowly, my hair grew back." Chen Jue said to Teacher Wu. She panicked a little and ran her hands through her short, thick hair.

For a man, having hair or not makes a big difference.

"Is Chinese medicine so effective?"

"Ahem... Then I'll go back and prescribe some Chinese medicine to try." Wu Fang coughed a few times, obviously the flu hadn't completely healed yet.

Chen Jue has read the news online these days. It is said that influenza viruses and mycoplasma pneumonia have been spreading very violently recently, and they are still stubborn viruses. There are no particularly effective medicines. Ordinary people can have coughs for more than a month after being infected.

Wu Fang was able to get better within a week, which is obviously due to her strong resistance.

Going to bed early and getting up early every day, plus frequent morning exercises, his physical fitness is obviously much better than that of ordinary people.

At this time, Zheng Yuan, who was arranging test equipment in the classroom, came over and said: "Brother Jue, I have specially invited a very qualified senior to come over and check for me on this subject."

"I'm going to trouble you and my sister for the test later! After the test, I'll treat everyone to a big dinner at noon."

"Okay, just ask if I want to cooperate with you." Chen Jue nodded and took out all the various dart props he had prepared before.

Wu Fang also brought a red tassel gun and a rope dart. Although he was still sick, it didn't seem to have much impact.

Unexpectedly, while chatting with Wu Fang about the last live broadcast, an unexpected person appeared.

I saw Zhou Chuan walking into the training venue from outside the door holding teaching materials and a laptop.

"Huh?"

"Senior Chen, why are you here?" Zhou Chuan was a little confused.

Because Chen Jue was on his follow-up medical record list, Zhou Chuan was very impressed by him.

"I'm here to cooperate with Zheng Yuan in doing the test." Chen Jue greeted him, thinking that Jiang University's campus is really small.

Unexpectedly, the second-year graduate student invited by Zheng Yuan turned out to be Zhou Chuan, a super academic who is famous in Jiangsu University!

But when I think about Zheng Yuan's weird topic, it makes sense to invite Zhou Chuan, who has a similarly clear mind.

"You? Cooperate with Xiaoyuan for testing?"

"You are the darts master he was talking about!" Zhou Chuan was also a little stunned and looked at Chen Jue again with curiosity on his face.

He was a bit mistaken about the meal he had before. He didn't expect that Chen Jue, an auditor suffering from gallstones, would have such a hidden ability.

"Senior Zhou, I'm going to trouble you to control the physical test data this time!" Zheng Yuan's people were all present, and he enthusiastically introduced everyone.

There were a total of 8 people present to cooperate in the test. In addition to Zheng Yuan and his girlfriend, his three roommates were divided into the ordinary people control group.

Chen Jue and Wu Fang, two invited outsiders, were classified as the experimental control group of martial artists.

"Martial artist?"

"I haven't even taken a certificate certification exam, how can I still bear this title?" Chen Jue looked at his name being entered into the test system, and suddenly became a little amused.

As for Wu Fang, she cooperated and took out a first-level athlete's qualification certificate and a Wuying-level martial arts rank certificate.

The level standards for martial arts athletes are slightly different from ordinary athletes. From low to high, they are: martial arts boy, third-level samurai, second-level samurai, first-level samurai, martial arts class, and international martial arts class.

In order to obtain Wuying-level certification, at the very least, one must place in the top three in a national first-level martial arts championship.

"I didn't expect Teacher Wu to still hide it so deeply!"

"You should be able to check the videos of the martial arts championships over the years online, right?" Chen Jue stared at the martial arts certificate for a few more times.

Wu Fang obviously noticed Chen Jue's curious gaze, and her face suddenly turned red. After taking a photo of Zheng Yuan, she hurriedly put the two certificates into her small bag.

…

After a few people met and got to know each other, they started to get down to business.

According to Zheng Yuan, there are several test contents, including the human body's visual dynamic capture ability, body reaction speed, personal wrist strength, and the lethality of darts after being released, etc.

The control group of ordinary people went up first to take the test. Zheng Yuan and several of his roommates put on similar VR glasses and started taking the test.

Chen Jue, Wu Fang, and Zhou Chuan were watching the feedback data projected on the screen.

"Zheng Yuan: 15 frames with naked eyes"

"Lin Xiaoyue: 17 frames with naked eyes"

"..."

"Brother Zhou, is this frame rate the same unit as the refresh rate of a computer monitor?" Chen Jue asked curiously, looking at the feedback data on the screen.

Zhou Chuan nodded and explained: "It almost means the same thing, but there are some differences. Because the average reaction speed of our human eyes is about one-tenth of a second, which is about 100 milliseconds."

"If you want to test the dynamic capture ability of your personal vision, the best way is to use the naked eye to distinguish the number of frames in the picture to determine the upper limit of the eye's capture ability."

"For example, the film industry used to use the 24-frame standard to shoot movies, which means a total of 24 frames are displayed in one second, and each frame stays for 41.6 milliseconds. If it exceeds 24 frames, it will be difficult for ordinary people to see the breakpoints in the frames. . Now we are starting to use digital film technology with 60 frames or more, and the picture will be clearer."

"The refresh rate of the computer screens we use every day is basically around 60 frames. However, there are still differences between computer imaging and movie images. This involves the two concepts of dynamic blur and continuous vision. The images produced by the computer are all single photos, and Motion blur technology will be inserted into the movie images during the shooting process to make the images look smoother."

Zhou Chuan said and pointed to the laptop he brought, which was displaying the test screen played in the VR glasses.

It was a scene of a black ball flying sideways against a white background. However, due to the continuous increase in the number of frames, the black ball would have obvious breakpoints during its flight until the breakpoints almost disappeared.

The test done by Zheng Yuan and the others was to capture the breakpoints between each frame with the naked eye.

Once the breakpoint disappears at a certain frame number and the black ball you see flies across the screen in a completely smooth state, it means that this frame number has reached the capture limit of eyeball vision.

"It turns out that this is the principle!"

After listening to Zhou Chuan's analysis, Chen Jue showed a look of sudden enlightenment. He thought that these top students from top universities were so smart that they could come up with such a straightforward method to measure eyes.

After Zheng Yuan and others finished testing, Wu Fang went up first and put on VR glasses for testing. The test result was 26 frames, which was equivalent to her being able to see a dynamic picture that appeared in 38 milliseconds at a glance.

Compared with the previous test data of the ordinary people control group, Wu Fang's eye catching ability is particularly outstanding.

"It's my turn!"

Chen Jue was a little eager to try it, because he had been doing [eye exercises] for more than a month, and he didn't know how far his visual ability had improved.

I just took the opportunity to provide Zheng Yuan with the project data to test the limits of my vision.

"Come on! Master Chen!" Wu Fang took off her VR glasses to cheer Chen Jue up.

Chen Jue smiled and nodded, took the glasses and put them on before starting the test.

As for Zheng Yuan and others, they also gathered around Zhou Chuan and looked at the test screen on the laptop.

I can see that the black ball flying horizontally in the screen is constantly accelerating as the number of frames increases, and the frequency of breakpoints when the black ball moves is also decreasing frame by frame.

First it was 10 frames, then 20 frames, with fewer and fewer breakpoints, until it passed the limit of 24 frames for ordinary people. Zheng Yuan and the others who were staring at the screen could no longer see the breakpoints.

But Chen Jue had no intention of stopping at all!

At 25 frames, 28 frames, and 30 frames, the black ball became smoother and smoother in the picture. It was not until 40 frames that Chen Jue pressed the pause button and took off the VR glasses.

"No, the breakpoint won't be visible after 40 frames." Chen Jue turned around and said to Zhou Chuan.

Unexpectedly, everyone around him, including Wu Fang, was staring at him like a god.

"Naked-eye 40 frames?"

"Brother Jue, do you have such strong eyesight?"

"It's a bit abstract! Does practicing martial arts and darts have such a strong effect on improving eyesight?"

"With this vision, you can probably see the flight path of a bullet, right?" Zheng Yuan and several of his roommates shouted.

On the other hand, after Zhou Chuan saw Chen Jue's ridiculously high test data, he also behaved in a very novel way. His eyes lit up as if he had discovered a treasure: "40 frames, 25mm visual capture ability is a bit amazing. !”

"But it's almost impossible to see the bullet with the naked eye."

Zheng Yuan and others were slightly startled when they heard this: "Senior Zhou, how many frames does it take to see the bullet?"

Zhou Chuan smiled slightly after hearing this, picked up a pen and paper and calculated at the scene as if no one else was around: "The width of the VR glasses screen where the black ball moves is 140mm. Assuming that the weakest pistol is used to fire bullets, the initial flight speed of the bullet is 300 meters per hour. Seconds, calculate that it only takes 4.6 milliseconds for the bullet to fly across the screen."

"That is, it requires nearly 217 frames of visual capture capability to see bullets flying across the screen."

"However, human vision has its limits. It takes time for us ordinary people to see the target object and react to the brain imaging. Just like when we take pictures with our mobile phones, after clicking the photo button, there is a pause in taking the photo. And this The visual imaging time is related to the individual's optic nerve transmission speed. Foreign research data fluctuates around 20 milliseconds, and even the Maasai people with the best eyesight cannot break through the 20 millisecond limit."

"So it is impossible for a normal human being to see the flight path of the bullet in his lifetime."

"If you can see bullets flying, you're not a normal human being, but you're filming The Matrix's bullet time."

Everyone present was completely impressed by Zhou Chuan's data analysis.

It is indeed a learning disorder!

All kinds of weird data about the human body are at your fingertips, and you can analyze and calculate them on the spot. It really opened the eyes of undergraduate students like Zheng Yuan.

Even Chen Jue and Wu Fang were slightly lost in thought. They looked at each other and exchanged the shock in each other's eyes.

"20 millisecond visual imaging limit?"

"Then if I consume free attribute points and add points to the eyeballs and optic nerves through [pointing], will it break this limit?" Chen Jue thought to himself and started the next test session.
