Donghai, Academy of Military Sciences.

"Professor, I have an idea, if it succeeds, it feels scary to think about."

Fang Yuan was a little excited, and gave a thumbs up to the ability linkage effect he had just thought of.

However, for the time being, it is just an idea and has not been tested yet, so it is not sure if it will succeed.

"Tell me about it."

Yang Yuping has a lot of scientific research projects recently, and he has been doing research almost sleeplessly.

Hearing that Fang Yuan was coming, he sat down, took a sip of tea, rubbed his eyebrows, and rested for a while.

"That's right, in ultra-low-altitude flight, the biggest drag is air resistance......"

Fang Yuan slowly said his thoughts: "Because of the existence of air resistance, I can easily soar to Mach 10 speeds in the ionosphere, but on the ground, reaching Mach 3 is already the limit.

"I was thinking, if we could just remove the air resistance, wouldn't it be possible to easily soar to Mach 10 speeds like in space?"

Yang Yuping took a breath and said with a smile: "What you want to say is the 'vacuum realm', right?" ”

"That's right." Fang Yuan nodded.

"The General Staff of the Theater has handed over the relevant documents and asked the laboratory to do a feasibility study, and I have already handed them over to Da Liu to get them." Yang Yuping replied.

"Uh...... The General Staff has already thought of it? Fang Yuan was a little surprised.

"It's not surprising that bringing out all the potential of super soldiers is the main job of the Academy of Military Sciences' Academy of Awakened Ones. The Academy of Military Sciences is going to ask you to test the data of the 'vacuum field' after a while, and then enter it into the database. Yang Yuping picked up the teacup and prepared to pick up some boiling water.

Fang Yuan hurriedly brought the teacup over and said, "I'll come, you can rest for a while." ”

"Da Liu should have started to do data analysis in the 'vacuum field', since you are here, I will go to Da Liu later and conduct a test in this regard." I'm still working on materials with strong interactions. Yang Yuping took the teacup full of boiling water and said thank you.

……

Came out of Yang Yuping's office.

Fang Yuan called Da Liu, asked him where he was, and went to the test site to find him.

"I want to do the 'vacuum field', a test to eliminate air resistance."

Da Liu pushed his glasses and said with some excitement: "I read the plan given by the General Staff, if it is successful, it will be amazing."

"However, before testing the effect of the linkage, you have to do a physical examination first, and then test the data of the 'vacuum field'. The data I have now is all analytical data obtained through visual inspection. ”

"Of course you can, let's get started now." Fang Yuan agreed.

The first is a physical examination.

"Weighing 90 kilograms, it's a bit heavier than before." Da Liu and the team of the Academy of Military Sciences recorded the physical examination data together.

"Why is it heavy again? One hundred and eighty pounds, it sounds like I'm the same size as beef balls. Fang Yuan complained.

"This is very normal, the stronger the strength, the density of bones, muscles and other body tissues will increase, especially the density of bones. Anyway, as far as I know, the Red Dragon General weighs a lot. Da Liu explained casually.

Fang Yuan's appearance looked like a sturdy body, if it was an ordinary person, it would definitely not reach one hundred and eighty catties, and only a high-level awakened person could reach such a weight.

"There is a residual star source energy in the mitochondria of the cell, which is similar to the situation last time, there was no problem last time, and it should not be a big problem this time. However, it is better to digest the remaining star energy in the mitochondria as soon as possible. Da Liu then reported the results of another physical examination.

After the medical examination, the "vacuum field" test will begin.

Da Liu made several test plans last night, and they happened to be used today.

The first is to test the mechanism of action of the "vacuum field", which was found to be very peculiar after testing.

At the moment of release of the "vacuum field", the air within a radius of thirty meters directly disappeared.

This phenomenon is very peculiar.

The research team sprayed colored gases in the air to see how the air moved.

However, the colored gases within thirty meters simply disappeared, while those thirty meters away remained in their original state.

When the "vacuum field" is turned off, the original air will reappear.

"Strange, how can this strange phenomenon occur?" Da Liu was very puzzled.

"Try to observe high-dimensional space." Fang Yuan thought of a possibility.

So, I called Ye Zheyu and observed it through the "High-Dimensional Vision Eye".

Eventually, the disappeared air was transferred to a high-dimensional space, turning the field into a vacuum.

This makes the mechanism of action in the "Vacuum Realm" very peculiar, and the ability is far more powerful than you think.

However, after more testing, some characteristics of the "vacuum field" were also determined.

This ability only works on small molecules, meaning it can transfer air and water to higher-dimensional space, creating a "vacuum field," but it has no effect on large rocks.

It seems to be related to the dialysis scale of the dimensional membrane, which can only allow small molecules to pass through the dimensional membrane, but not large molecules.

"Let's start testing vacuum acceleration." Fang Yuan took the initiative to ask.

"Okay, put on the speed measuring instrument, and after you start, go straight to the sea, the land can't accommodate you anymore." Da Liu handed a speedometer to Fang Yuan and casually made a joke.

When there is air resistance, Fang Yuan can soar to a speed of Mach 3, and it is very dangerous to run around the city at this speed.

Of course, it was not Fang Yuan who was in danger, but others who were in danger.

After everything is ready.

Fang Yuan took a starting stance, activated the "Vacuum Domain" and "Lightning Speed", and roared with a thunderclap and shot out.

Since we are in a "vacuum", there is not a single air molecule around, so there is no air resistance, and naturally there is no sound barrier.

So, there was no sonic boom.

Fang Yuan shot out, rushed to the sea, and ran wildly on the sea.

The "vacuum field" creates an area where there is no air, so in the absence of air resistance, the speed is getting faster and faster, to the point of being frightening.

Da Liu looked at the data on the computer and shouted in the communication channel: "Fang Yuan, speed Mach 5, Mach 6, Mach 7...... It's still improving, which is a bit of an exaggeration.

"Don't rush too fast, you can retain a little bit of strength in the first test."

Fang Yuanzheng was excited, so he didn't care so much, and continued to gallop forward.

Moreover, this also uses the "lightning speed", and the lightning vortex propulsion has not yet been activated.

Theoretically, if there is no air resistance and acceleration can be maintained, it can be accelerated all the way to close to the speed of light.

Of course, this is a theory, and if you want to get close to the speed of light, it's not that simple.

Moreover, to approach the speed of light, the process of light acceleration will take several years.

Therefore, Fang Yuan didn't need to think about these problems now, but wanted to soar out of an extreme speed at an ultra-low altitude.
