Chapter: 85

"Found it!"

Mark led Rhodey to his room and spent nearly half an hour rummaging through his collection room, finally finding a dusty metal briefcase.

"This is it! I was thrilled when I created it, but unfortunately, due to the technological limitations back then, even with pure silver as the material for the supercapacitor, the battery life was still unsatisfactory. So, I kept it stored here and never brought it out again.

Later on, even though there were better capacitor technologies and more practical power supply solutions, compared to my new invention, this piece's practicality was somewhat limited, so I didn't upgrade it."

As Mark introduced his long-forgotten invention to Rhodey, he opened the combination lock on the briefcase. Click - the lock opened, inside the small briefcase was a cylindrical object measuring no more than 20 centimeters in length.

The invention was silver-gray in color, with a red circular button in the middle. At the bottom, there was a circular groove that seemed to require some additional components. On the top was a beautifully cut crystal, and other than that, Rhodey couldn't see anything particularly special about the object.

"How do you use this thing?" Rhodey picked up the silver-gray cylinder and fiddled with it, but he had no clue.

"It needs to be equipped with a supercapacitor to function. Let me see if I have a fully charged one... Ah, here's one!" Mark found a usable supercapacitor from his cluttered toolbox and placed it into the groove at the bottom of the cylinder. With a click, the capacitor locked into place, and the unknown crystal on top emitted a faint glow.

"This thing can be described as a personal shielding field or a spherical shielding field model.

The invention consists of a supercapacitor at the bottom for power supply, a Hohmann field effect generator in the middle, and an imaging device at the top.

The electrical energy inside the supercapacitor, after passing through the Hohmann field effect generator, forms a spherical energy shield that prevents any object from entering it.

The imaging device at the top indicates the range and intensity of the energy field. The higher the imaging brightness, the stronger the shielding field, and vice versa."

"Wait!" Rhodey interrupted Mark's self-absorbed explanation and straightforwardly said, "I don't understand all these principles. Just tell me 'how to use' and 'what it's used for.'"

"Alright, to put it simply, the amount of energy in the capacitor determines the shield's ability to withstand attacks of equivalent energy. And the larger the device and the capacitor, which means more energy. So, compared to a personal device, when applied to a larger scale, it can withstand more intense attacks."

"You mean, this invention can be used not only by individuals but also scaled up to a larger range if someone has the capability!" Rhodey looked at Mark in disbelief, his face filled with astonishment.

Although this invention didn't possess any offensive capabilities, the impact it brought surpassed even that of Transformers, leaving Rhodey wide-eyed in amazement.

"That's about it. But as I mentioned earlier, this invention has a major flaw - energy. To maintain its operation for a long time, it requires a supercapacitor with a large capacity while remaining lightweight and portable. The only material that meets these criteria is graphene, and currently, Mark Research Center is the only company holding the patent and capable of mass-producing graphene. In short - if you want to use it, you'll have to pay up!"

On the other hand, if we want to expand the defense range, besides the considerable construction and material costs, filling the huge capacitor with electricity is also a massive expense. Currently, the only source of large and inexpensive clean energy in the world is the Ark Reactor in my father's hands. If someone wants to use it, they have to pay.

In other words, if I submit this invention to the Military Committee, it may seem like a compromise on my part, but in reality, they will not only have to give me and my father a large amount of money every year, but we will also control a supply chain. This transaction is a guaranteed profit for me.

Rhode nodded in agreement with Mark's viewpoint. "It's a win-win deal. You and your father can get rid of the Military Committee's interference, make a big profit, and secure a protective shield for yourselves. As long as you grasp the military's supply chain lifeline, they won't dare to target you easily..."

"However, all of this relies on the reliability of your technology" Rhode said. He wasn't doubting Mark's abilities, but he needed to see the protective capabilities of the shield in action before he could use it as a condition to negotiate with the Military Committee.

"Then let's give it a try."

Outside the Stark Mansion, Rhode sat in his car with Mark, feeling a bit nervous and concerned. He asked, "Are you sure we should do this?"

"Ah!" Mark sighed impatiently. "Uncle Rhode, this is the twelfth time you've asked me this question in the past 10 minutes. I'm certain, absolutely sure and confident. Just step on the gas pedal and crash into that tree. I guarantee the shield will protect your car, it wouldn't even get a scratch. If anything happens, I'll buy you a new one."

"Alright! Since you say so, Uncle can rest assured." Rhode wasn't worried about their safety. Apart from the high-tech suit Mark was wearing, he had confidence in the seatbelt and airbags of his own car.

His only concern was his beloved car. After all, he wasn't as rich as the Stark family. If it got damaged, he would be heartbroken.

Vroom! Rhode released the brake slightly and then stepped hard on the accelerator. With the roar of the engine, the car quickly accelerated and collided head-on with the tree in front.

"... " After a while, realizing that he didn't feel any impact from the collision, Rhode slowly opened his eyes.

In front of him was the shield produced through the device. The image crystal's brightness had dimmed significantly compared to before the impact, indicating that it had consumed a lot of energy to withstand the collision.

The unfortunate tree that was selected as the target had been reduced to debris under the effect of the shield, rather than simply breaking like a normal collision.

Rhode cautiously shifted into reverse and backed up the car. The car was still functioning and ran smoothly. Remembering that he didn't feel any impact during the collision, Rhode looked at Mark and smiled with a meaningful expression.
