Following in Zhou's footsteps, after five or six minutes of twists and turns, Zhou led Wade to a room with only six staff members, about fifty square meters.

The room is not too big, only about five meters high, the walls around it are made of high-hardness alloys, and the surveillance cameras cover every corner of the room, with almost no dead ends.

The room was simply set up, with only a giant three-meter-long treadmill and other bizarre equipment, each with a high-definition monitor on one side, and five staff members each holding a tablet to check the data fed back by the equipment.

In the center of the room, there was a young oriental man in a white coat, he looked average, had an inch of hair, and the whole person looked very energetic.

His name is Wang Tong, and he is the head of the testing department of the WBS Huaxia Branch, and he is also the boss of this room.

The testing department, as the name suggests, is a family that the WBS specializes in evaluating and testing the abilities of new species, because the abilities of new species are diverse, and it is very troublesome to test them together, so the WBS divides the testing department into multiple small parts for testing different new species.

And what Wang Tong is responsible for is the most basic physical quality abilities, such as speed, strength, physical strength and other non-control abilities.

"Director Zhou, you're here, this seems to be Wade, right?" Wang Tong didn't seem to show much surprise at the arrival of Zhou and Wade, and after he saluted Zhou and Wade, he carefully looked at the seventeen-year-old European boy in front of him, and seemed to be a little curious.

Zhou nodded in approval: "Yes, are the instruments ready?" ”

"Well, you can start at any time." Wang Tong turned sideways and exposed the three-meter-long giant treadmill behind him to the two of them; Wade consciously opened his legs, walked to the side of the treadmill, and watched carefully.

"This treadmill is a new species specially designed for leg mutations, it can keep up with the ultra-high speed of up to 10,000 meters per second, and can withstand dozens of tons of pressure without collapsing, so you can run freely."

Wang Tong came to Wade's side to give a general introduction to the performance of this super treadmill, Wade looked at the treadmill, listened to this piece of data, and his heart fluctuated.

This level of technology is not at all what the world understands, not to mention the super treadmill in front of him, which is the entire branch, is beyond Wade's imagination.

"How much are the governments of various countries still hiding from the outside world?" Wade asked in his heart.

"It's so convenient, you don't know, before that, I had to go to the abandoned airport outside Osaka and spend more than ten minutes setting up a kilometer-long speedometer, which is very tiring." Wade complained to Wang Tong with a smile on his face, in his opinion, the people here are quite kind, and of course he does not rule out the possibility of pretending.

"So can you get started?" At this time, there was no room for Zhou to interject, and he dropped a sentence, "Send me the data when it's over." Then he took a big stride and turned away, as if there was still something to be done.

"Okay, Director." Wang Tong said to Zhou Yuan's figure, at this time, Wade was also ready to warm up and stepped on the track of the treadmill.

The tracks are made of hard alloy with soft straps underneath, which not only slows down the impact of each step of the tester, but also does not hurt the tester's feet, well, quite user-friendly.

"Wait a minute." Seeing that Wade had already stepped on the treadmill, Wang Tong unhurriedly pulled out a flexible metal safety belt from both sides of the treadmill to lock Wade's entire torso, which is a protective device, if Wade is shot out because he can't keep up with the speed of the track, these two safety belts will be triggered instantly, dragging Wade, and cutting off the power at the same time.

"Okay," Wang Tong clapped his hands after doing this, and at the same time tapped on the monitor next to the treadmill, "the speed of the track will gradually increase, all you have to do is run, and the sensor will record everything." ”

“ok。” Wade responded, and the tracks under his feet began to turn, forcing Wade to spread his legs and accelerate as the tracks accelerated.

A few seconds later, as the speed of the track accelerated, Wade's pace became more and more dense, and in a blink of an eye, many golden lightning bolts had appeared around him, and his legs were like a video after the video was about to be played, dragging out a burst of afterimages, even if he concentrated on looking, he couldn't distinguish the position of Wade's legs, and after staring at it for a long time, he would feel dizzy, and his eyes would be unable to bear it and close.

Wade was in perfect condition today, he felt as if he had lost any weight after he started running, and the wind used to simulate the real situation whistled out from the blower in front of him, but it was blocked by the lightning around Wade, and did not slow down in the slightest.

Now it seems that these lightning bolts are similar to the speed force in the Flash's setting, which can block the resistance of the air to Wade, so as to increase his running speed.

After running continuously for more than half an hour, Wade still didn't feel any tiredness, if it weren't for Wang Tong stopping Wade with a slightly startled expression, he seemed to be able to run for a few more hours without rest.

After getting off the treadmill and standing aside and waiting quietly for a while, Wang Tong finally moved away from the monitor and returned to Wade with the tablet.

"The result? When I was running to the limit, I always felt as if there was an invisible barrier around me that limited me and prevented me from further increasing my speed, so this can't be the so-called bottleneck, right? ”

Seeing the strange expression on Wang Tong's face, Wade didn't feel good in his heart, when he just started running, Wade's feeling was very comfortable, without the slightest discomfort, everything was so natural; But when a fifth and a half hours had passed, he clearly felt that there was an extremely resilient barrier in the space around him, which was difficult to break through, restricting his further acceleration.

"Let's just put it that way...... For the next ten minutes, your speed remained at three hundred and thirty-nine meters per second, without falling or rising. The expression on Wang Tong's face became more and more strange, and he looked at Wade as if to say, "What kind of monster are you?" ”

"Three hundred and thirty-nine meters per second, that's not ...... Isn't that a difference of one second in the speed of sound at one atmosphere? Wade instinctively filtered Wang Tong's strange gaze, and he rubbed his chin with his hand thoughtfully: "So the barrier I just felt is actually a sound barrier?" ”

Wang Tong nodded silently and agreed with Wade's conjecture.

"That's great, too." Wade slammed his fists and palms, looking like he suddenly realized, now he was in a good mood, infinitely close to the speed of sound, which means that his speed is shortening the gap with the time when he just woke up, and it also means that he is about to return to a high-speed world that cannot be captured by the human eye, even after dynamic visual transformation.

Thinking of this, Wade couldn't help but ask Wang Tong again: "That...... Mr. Wang Tong, to tell you the truth, during the time when I just awakened my ability, the highest speed record reached more than 500 meters per second. ”

Wang Tong was not stupid, after hearing the meaning of Wade's words, he immediately stopped the movements in his hand and focused his attention on Wade's body.

"But since then, for some reason, my speed began to slow down gradually, and finally stabilized at a speed of more than 100 meters per second, at least the last time I tested, I barely reached a speed of more than 200 meters per second, so I ......"

"Sub-material decline, that's normal." Wang Tong said without changing his face, he had recovered from the surprise just now, and his tone tended to be calm.

"What's that?" Wade raised his left eyebrow and asked suspiciously.
