253: Hanging people

When Xu Bai mentioned gravity, he thought of the center of gravity, so he brought that up as well.

“I define the center of gravity as the equivalent point of action for all the gravitational forces acting on an object. In other words, even though every part of an object experiences gravity, I concentrate the total effect of this gravity at a single point.

The reason I establish the center of gravity is to more easily control the center of mass distribution of an object, making it easier to maintain a stable state.

Finding the center of gravity of an object is also very simple; you just need to suspend the object, and the intersection of the vertical lines from two different suspension points will be the object’s center of gravity.

For practical application, look at this drone. I designed its four corners to be identical, so its center of gravity is at the central switch.

Let’s assume there’s a downward gravitational force here. Because the object has this gravity, to fly up, it needs an upward force greater than gravity.”

Hearing this, Sun Puge began to understand.

It’s like picking up something from the ground; when you lift it upwards, the upward force needs to be greater than its gravity. When it’s equal to gravity, it’s like holding the object still.

This was quite easy to understand.

He looked at the fans on the four corners of the drone in his hand and speculated,

“Is it that the wind blown downwards by these four fans gives the drone an upward force, and then this force’s magnitude is adjusted according to the wind speed? When the force is greater than gravity, it flies upwards.”

“Correct.”

Sun Puge looked at Xu Bai with a complex expression.

Xu Bai blinked.

“Write a paper about these things you mentioned, like gravity and center of gravity.”

Looking at Sun Puge’s eyes, Xu Bai finally realized how important these widely known concepts from his previous life were in this world.

Newton was a great master.

This meant that if he brought out this knowledge, he too would become a great master.

Thinking this, Xu Bai felt a little shy, but he quickly calmed down. He wouldn’t worry about the future; he would just focus on the present… One hour later.

Everyone arrived at a spacious open field. There were mountains and water in the distance, and the scenery was pleasant.

This place was not far from the Research Institute and was specifically used for testing, so the procedures to come here were not complicated.

Many people came to watch the test, including not only people from the Research Institute but also from the military.

The primary goal of the military personnel was to protect the people of the Research Institute, especially the Administrator and Researcher, and secondly, to see this ‘new weapon.’

Which soldier doesn't like weapons?

Although Xu Bai had said many times that it currently had no weapons and was at most a flying device, everyone was still very curious… “Begin.”

Xu Bai gave the command.

For this drone test, Xu Bai chose Fan Jiaping as the operator. The reason, of course, was that he was more daring and willing to make various bold maneuvers with the drone.

At the same time, from the previous evasive actions, he could see that Fan Jiaping’s drone operating skills were very high. Some people are just like that; even without extensive practice, they can perform well—it's a gift from God.

Fan Jiaping was overjoyed. He hadn’t expected not to be treated unfairly, but instead to be favored by Researcher Xu. This also meant a bright future for him.

Thinking this, he secretly vowed to do his best and not disappoint Researcher Xu’s trust.

Fan Jiaping followed Xu Bai’s instructions and started the drone; it flew up.

Everyone from the Research Institute had seen this scene before, so they weren’t surprised, but the soldiers nearby, seeing it for the first time, couldn’t help but widen their eyes.

It really flew!

This time, the drone didn’t stop quickly in the air but kept flying upwards.

The drone in everyone’s eyes became further and further away, smaller and smaller.

However, it didn’t leave people’s sight, because the current drone didn’t have any real-time monitoring equipment, so losing sight of it would be meaningless.

Xu Bai also realized at this point that the drone not only needed weapons but also real-time video, allowing the operator to see the drone’s perspective.

“Come down a bit to test other things.”

Fan Jiaping immediately controlled the drone to descend. He knew that what followed was his moment to shine.

The drone, after descending from a high altitude, circled above everyone’s heads three times before diving downwards, without reducing speed during the dive.

In the eyes of others, the drone seemed to be out of control and about to crash into the ground, so they held their breath and waited.

The drone pulled up again when it was about half a meter from the ground, then it flew next to a tree and circled around it.

Watching this maneuver, some people had an idea: if the tree were replaced with a mutated beast, it could work the same way. With weapons mounted on the drone, flying around the mutated beast would ensure that the desired target was hit.

Immediately after, Fan Jiaping controlled the drone to perform figure-eight flights, barrel rolls, and other maneuvers, leaving everyone dazzled.

Xu Bai felt that he was a true talent; he could master the drone so quickly. Afterwards, he could even be sent to teach others how to operate drones… Administrator: “How do you plan to arrange the weapons later, and which weapons do you want to include?”

Xu Bai: “My idea is to install fixed weapons on the bottom or top, or suspend weapons with ropes. I haven’t decided which specific weapons to arrange yet, and I don’t know what specific weapons are available.”

Sun Puge offered his idea.

“If they’re suspended, it’s hard to control. Oh, if your load-bearing capacity is good, how great would it be to just suspend a person there? After all, people can adapt. Xu Bai, if you enlarge the drone, can a person sit on it?”

The soldiers nearby pricked up their ears, listening.

They were also very curious about this; if a person could get on, how cool would that be!

Imagine flying in the sky, attacking and strafing the mutated beasts below, or flying over and throwing grenades into piles of mutated beasts—how wonderful that would be.

The more they thought about it, the stronger their impulse grew.

Humans could already develop into the sky.

“Indeed, a person could get on a larger one, but it wouldn't be safe. There’s no protection whatsoever, and not everyone can operate a drone so skillfully. One misstep and they could fall from the sky.”

The soldiers’ gazes were almost tangible, and Xu Bai quickly brought up the safety issue, hoping to dispel everyone’s ideas.

Imagine a person suspended hundreds of meters in the air, relying only on ropes and the control of teammates below. Xu Bai felt a little scared just thinking about it. If they weren’t killed by mutated beasts but instead fell to their death, how not worthwhile would that be?

Such a situation was one he didn’t want to see, so he wanted to refuse.
