Using the mode of holding an umbrella to land safely, this is what Chen Duan thought of temporarily, if it was before, he would probably die a miserable death, but after the human body shrunk, it became a fact that could be realized, the physical principle of this, Chen Du and Tang Jing discussed, but they didn't dare to try it at that time.

To complete the action of holding the umbrella at the last moment, even he himself is not completely sure.

It's a bit risky.

Of course, he didn't just do it to be cool.

The first is to verify whether it can land safely; Second, and most importantly, Chen Du thought of the situation when he subconsciously used his shield when he faced those three strange enemies.

Maybe people can really exert extraordinary abilities in a crisis.

He knew very well that even if he couldn't open the umbrella, he wouldn't fall to his death, but his psychological fear of the air would not be reduced much.

It's a bit risky, but it's worth it to prove that fact.

It turns out that if people don't push themselves, they may never know where the upper limit is.

Chen's guess was correct.

That moment.

The speed of the brain seems to be working faster, the body is becoming more flexible, and the control of the ability is much faster than normal, which is by no means possible with adrenaline alone.

Chen Du put away the umbrella and glanced back at the height, feeling a little scared.

"When have you practiced this move?" He Ying's only strength was also surpassed, and she pouted and looked unhappy.

"I haven't practiced, I thought of it temporarily."

He Ying: "......"

While everyone sighed, Tang Jing looked up at the location of the lookout and was silent for a long time.

Dong Junwei asked, "Is there any problem?" ”

Tang Jing said: "I suddenly thought of something......

"What?"

"Do you know how much time it took Chen Du to jump down just now?"

"How much time? How do you know, it's a ...... anyway All of a sudden, it came down. ”

"Okay, I'll change the question." Tang Jing smiled: "How long does it take for an object to land in free fall from a height of 80 centimeters if air resistance is not considered?" ”

"I've done that." Du Jiajia was the first to raise her hand: "But without pen and paper, I can't figure it out." ”

The free-fall formula, something that I learned in junior high school.

Tang Jing said: "I'll tell you directly, it's 0.4 seconds." ”

"So what?"

"Don't you think it's strange?"

"Seems to be pretty fast......"

Chen Du was the first to understand: "It's the reaction speed." ”

"Hmm."

Tang Jing nodded: "In fact, air resistance needs to be considered, but even then, it will definitely not exceed 0.5 seconds, that is to say, Chen Dui, you have just completed a series of actions in 0.25 seconds." ”

"What a quick response." The crowd was stunned.

"No, not the problem." Tang Jing shook his head: "If it's just Chen Duan, then it's easy to understand, but all of us can see his movements clearly, don't you think it's strange?" ”

"This ......"

"Okay, let me change the example, take He Ying just now, she didn't have any deceleration measures, and purely relied on her own flexibility to complete the landing, that is to say, the whole landing process is less than 0.5 seconds, what is the concept of 0.5 seconds, everyone should be clear, but the question is, what did you feel just now, is it really only 0.5 seconds?"

Everyone was speechless for a while.

Half a day.

Dong Junwei said: "It seems that there are two or three seconds." ”

"Almost."

"Seems like so."

Tang Jing said: "2 seconds, and 0.5 seconds, no matter how dull people are, they will not be confused." ”

Dong Junwei was puzzled: "You mean, the gravitational acceleration of all of us has changed?" ”

"Probably not." Tang Jing shook his head: "The gravitational acceleration has not changed, what has changed is our sense of time." ”

"Relativity?" Dong Junwei asked with some hesitation.

"Not to that point." Tang Jing smiled: "It's just that our own feelings have been deviated, or corrected." ”

"Why? I think the change in gravitational acceleration may be a little more reasonable. Chen Du did not immediately agree with Tang Jing's statement this time: "As I said before, there is some mysterious force that affects all human beings, so isn't it very reasonable to make certain changes to the gravitational force between us and the earth?" ”

Tang Jing said: "At present, all the modifications to human beings themselves are based on one principle, that is, let us live, in other words, if we do not change this way, human beings will not survive. However, gravitational acceleration, which is obviously not necessary. ”

"Hmm......" Chen Du thought with a frown.

"Of course, if this was the only one, I wouldn't be so sure, but, in retrospect, there was actually a precursor to this event, but we didn't realize it all along."

"What?"

"Do you remember that Luo Hui was taken away by the swallow?" Tang Jing looked around at everyone.

"Of course."

To this day, what happened to Luo Hui and Gu Ping is still a shadow in everyone's hearts.

Tang Jing said again: "At that time, which of you saw clearly that it was a swallow? ”

"I didn't see it clearly, I just listened to what Chen Du said."

"Me too."

"It seems like it's really ......"

“……”

When everyone was gossiping, Chen Du was a little embarrassed and said, "But I really, I can see clearly, it is indeed a swallow." ”

Tang Jing smiled: "Of course I don't doubt you, but, who can explain why you are the only one who can see that it is a swallow, you know, all of us were focused on Luo Hui at that time." ”

"This ......," Chen Duan hesitated a little.

Tang Jing didn't delay, and replied directly: "I guess, it's because of spiritual power. ”

"Mental power?"

"Luo Hui flew out of the window and was snatched away by the swallow in a flash, that is to say, the time when we saw the swallow was only the time when it flew over a window, according to normal circumstances, it is indeed impossible to see clearly."

"But Chen Du saw it clearly."

"That's because Chen Dui's mental strength has been stronger than each of us since the beginning." Tang Jing was very sure.

"Is there one?" This made Chen Du a little embarrassed.

Tang Jing said with a smile: "Until now, you are also the one with the fastest progress and the strongest mental power among us, I think it's not for nothing, talent should be a big factor." ”

Chen Du touched his nose, but it was difficult to answer.

Tang Jing continued: "The situation at that time was that each of us had awakened our abilities and possessed spiritual power, but Chen Duan was the strongest, so only he could see the appearance of the swallow clearly. ”

Although everyone couldn't refute it for a while, they always felt that something was wrong.

"So, the psychic power gives us the feeling of delaying time?" Dong Junwei asked.

"Not exactly, I think, it's that when we need it, the brain automatically adjusts to the sense of time and more accurately captures things that are too fast."

"For example, He Ying jumped down just now?"

"Yes, He Ying and Chen Duan jumped from the air, which made us instinctively concentrate, so that we could see more clearly, and our sense of time was greatly slowed down."
