“Hu…hu…hu…hu…hu…hu…hu…”

The afterimage of the anti-gravity box was connected into silver-white circles around Zhang Zhai. The sound of breaking the wind became stronger and stronger as the speed of the anti-gravity box became faster and faster.

“…11.2 Mach…13.6 Mach…15.7 Mach…21.3 Mach…33.4 Mach…”

The sound of A1 is getting faster and faster, and the anti-gravity box is growing faster and faster!

Zhang Zhai stood there, looking at the increasingly clear "circle" in front of him, and feeling the strong wind caused by the anti-gravity box when it rotates at high speed.

“Mach 36.1, Mach 38.4…”

"Hosh...hush..."

The sound of breaking through the air became more and more sharp and harsh, and the strong wind blew the laboratory paper documents all over the sky!

"Bang!...sher..."

Beside Zhang Zhai, the seat could not withstand the bombardment of the strong wind, and was hit hard on the ground and pushed out far away.

Zhang Zhai, who was in the circle, did not feel the strong wind, but he still half-closed his eyes.

“Mach 40.1…Mach 41.2…Mach 41.3…”

The speed is gradually rising slowly, and the anti-gravity box is about to reach its speed limit!

Sudden!

Just as the anti-gravity box crossed Mach 40, a sudden change occurred!

The originally silver-white anti-gravity box suddenly appeared a little red after the speed reached the critical point.

This point of fiery red is formed by the afterimage circle formed by the rapid rotation of the anti-gravity box technology, forming a fiery red thin line.

Immediately afterwards, in an instant, this thin thread spread rapidly to both sides, gradually swallowing away the original silver white at a speed visible to the naked eye.

In just a few seconds, the originally silver-white anti-gravity box turned into a fiery red as a whole, and the afterimage circle surrounding Zhang Zhai also became fiery red, like a fire circle burning with raging flames.

Zhang Zhai frowned and stared at the picture.

"Father, the high-speed anti-gravity box has severe friction with the air. The surface temperature of the anti-gravity box is rising very much, and it has now reached 2350℃. If the anti-gravity box continues to operate at high speed, it may cause the surface of the anti-gravity box to begin to melt." A1 prompted with a rapid voice.

Zhang Zhai shook his head and felt the hot temperature radiating outward of the 'fire circle', and said calmly: "A1, continue to monitor the speed of the anti-gravity box. Don't worry, the surface alloy of the anti-gravity box is not so easy to melt."

"Okay, father."

"The speed of the anti-gravity box is Mach 42.3, Mach 42.5...Mach 42.7...Mach 42.8..."

Zhang Zhai listened to the data that was growing slowly and slowly, and his expression did not change much. He quietly watched the anti-gravity box that was red due to the high temperature circling rapidly around him.

After one minute...

“Mach 44.1…Mach 44.2…Mach 44.3…”

As the speed of the anti-gravity box gradually approaches the limit, the speed of the anti-gravity box grows slowly, but it remains firm.

Five minutes later.

The circle formed by the afterimages around Zhang Zhai became more and more red, and it seemed like there were flames jumping constantly, and the temperature radiating outward became higher and higher.

At the same time, the speed of the anti-gravity box finally tends to stabilize, and the changes are getting weaker and weaker.

“Mach 44.5…Mach 44.4…Mach 44.5…Mach 44.5…”

Finally, the anti-gravity box reached its limit speed and completely stabilized.

"Mach 44.5, exactly five times the speed before..." Zhang Zhai looked at the fiery red afterimage circle in front of him, and it seemed that the anti-gravity box would burn or melt in the next moment.

"It's not bad, five times the speed can barely meet the requirements," Zhang Zhai said with a knowing smile on his face, and said with a smile.

"Anti-gravity box, start to slow down. After the deceleration is completed, retreat two meters ahead of me!"

As soon as Zhang Zhai finished speaking, instantly! The anti-gravity box that maintained its ultimate speed began to decelerate rapidly!

“Mach 40.1…Mach 33.3…Mach 26.3…”

The deceleration process is very rapid, and the speed drops more than double in just a few seconds.

The color of the afterimage circle gradually dimmed, and from fiery red to gradually restrain, the afterimages clearly connected into circles also became blurred as the speed decreased.

“Mach 20…Mach 15…Mach 10…”

Five seconds later, when the speed dropped to 1 Mach and passed by Zhang Zhai, the anti-gravity box reduced the speed from 1 Mach to 0 in an instant, and stopped suddenly in front of Zhang Zhai!

"Swish!"

The next moment when he paused, the anti-gravity box moved backward, leaving a afterimage in the air, and then retreated one meter again.

Two meters ahead of Zhang Zhai, in the air 50cm from the work surface directly below, the anti-gravity box hovered quietly in the air without moving.

The surface that was red due to the high temperature has faded at this moment. The surface of the anti-gravity box that seemed to have cooled down has become a little gray and black, and the shining color has become a little dull.

"Anti-gravity box, drop by 50CM." Zhang Zhai said with a smile on his face as intact as before.

"Swish!"

The anti-gravity box dropped by 50cm at a teleportation speed.

Next second!

"Sir...sir..."

A sound like a burning red soldering iron pouring into water rang out after the anti-gravity box contacted the work surface.

At the same time, a thick smoke also rose from under the anti-gravity box.

"Sir...sir..."

The originally faded fiery red rose from under the gray surface the moment it touched the work surface. The hot high temperature directly permed the work surface and imprinted a deep octagonal mark on the flat work surface.

"A1, notify several Terminators to come and restore the laboratory as before." Zhang Zhai looked around the laboratory.

At this moment, the laboratory seemed very messy, with paper materials scattered everywhere, stools and seats sloping upside down, and some small experimental equipment deviated from their original positions.

"Okay, father." A1 replied immediately.

Zhang Zhai nodded and then walked forward two steps closer to the anti-gravity box.

Zhang Zhai lowered his head, looked at the gray-black anti-gravity box on the surface, and smiled.

"It's not wasted time, and it can barely accept the speed of five times. At this stage, Mach 44.5 is the limit. If you want to increase the speed, unless there is a historic major breakthrough in the field of basic materials!" Zhang Zhai looked at the anti-gravity box and whispered to himself.

“…………………………………………”

Just as Zhang Zhai was observing the anti-gravity box, six terminators rushed into the laboratory at a constant speed and began to sort out the messy laboratory.

Zhang Zhai looked up and looked at it, "Come over and take the anti-gravity box and follow me."

"Dada..." A Terminator instantly stepped forward and picked up the anti-gravity box.

...

"A1, notify Academician Gan to go to the conference room on the second floor."

...

Ten minutes later.

In the second floor conference room, Academician Gan looked excited, staring at the anti-gravity box floating in the air, and did not move it away for a long time.

"Mr. Zhang, the anti-gravity box is really the most magical thing in the world. He suspended here motionlessly and subverted my understanding of physics." After a long time, Academician Gan came back to his senses and sighed,

Before Zhang Zhai could speak, Academician Gan continued, "Mr. Zhang, this is the modified anti-gravity box you mentioned, right?"

"Yes, this is the modified anti-gravity box." Zhang Zhai said with a smile.

"How much can the limit speed of this anti-gravity box reach? Mach 15, Mach 20, or Mach 30?" Academician Gan asked immediately.

Zhang Zhai Wenyan smiled and shook his head, "Academician Gan, your guess is actually a bit bolder. In fact, the limit speed of this anti-gravity box is Mach 44.5, which is exactly five times the speed of the previous anti-gravity box."

“Mach 44.5? Five times the speed?”

"right."

Academician Gan was stunned and stared at the anti-gravity box in a daze. His mouth opened slightly, and he wanted to speak but stopped.

...After a moment, Academician Gan finally reacted and said excitedly: "Mach 44.5, five times the speed! Mr. Zhang, you are really... really...

This is five times the speed. With this anti-gravity box, Mars landing can shorten the time at least five times!"
