The aliens who were picked up by Superman at the beginning

In the secret laboratory at the top of Wayne Corporation, cool white light was evenly distributed on the smooth metal floor, and dozens of precision instruments were emitting a faint hum.

Bruce Wayne shed his previous easygoing demeanor, donned a white lab coat, and his face gained a more composed and sharp expression.

This is the expression Li Zhen has in mind when she thinks Batman should have.

"The first item is the basic strength test."

Bruce pressed a button on the control panel, and the support platform in the center of the laboratory slowly rose. Behind the support platform was a massive buffer structure, as large as a mountain, with hundreds of nested piston metal tube structures resembling a ferocious monster.

The initial parameters are displayed synchronously on the screen in front.

"Strike the load-bearing plate with all your might, hold back."

Li Zhen frowned slightly. Although this metal behemoth looked terrifying, he had dismantled even more terrifying things in his past combat career.

Are you sure?

Bruce chuckled twice.

"This is specially made; Superman tested it here too."

One sentence directly dispelled all of Li Zhen's doubts, categorizing it directly into the category of incomprehensible black technology.

He nodded and walked to the load-bearing platform.

Li Zhen took a deep breath, and the dormant power within her body slowly awakened. The muscles in her right arm instantly tightened, and her originally well-proportioned arm visibly swelled up a bit.

The next instant, the fist slammed into the alloy plate with a whooshing sound, and the dull impact echoed in the confined space.

The machinery behind the load-bearing platform hummed, and the piston metal components of many lever structures began to move at a constant speed, distributing the force.

"boom--"

The numbers on the console screen fluctuated wildly, eventually settling on a chilling number.

Bruce's pupils suddenly contracted, and his fingertips slid rapidly across the screen, repeatedly confirming that the data was correct.

"A single impact force of 12.7 tons... Converted, the static load-bearing limit is at least 8 million tons."

He muttered to himself, his tone filled with barely concealed shock.

"This magnitude is enough to lift a medium-sized island tectonic plate—keep in mind, even the smallest Australian outlying islands weigh only 6 million tons. I heard you haven't fully adapted to your current strength yet."

"Uh, yes, before I escaped, I went through an unprecedentedly brutal battle. The Witrum people can gain very rational power growth through combat."

Li Zhen was not surprised by this. The Vitrum aliens were known for their strength, but he did not expect that his strength would increase to this extent after recovering from his serious injuries.

He moved his wrists, feeling the surging power within him.

"I can feel that this is not my true limit yet."

Next is the speed and neural response test.

The track on one side of the laboratory lit up instantly, and the high-speed moving target shuttled back and forth at several times the speed of sound, leaving behind afterimages.

Li Zhen moved swiftly, transforming into a blurry black shadow as she chased after the target. However, she was always a beat too slow, and once, due to her excessive speed, she crashed into and shattered several targets.

Fortunately, the Witrum people have excellent flying skills, and can even make difficult curves in extremely narrow spaces.

This prevented the aircraft from losing control and crashing into the wall.

However, this also shows that the Witrum's flight principle is different from Superman's. Superman's flight method, which cuts through magnetic fields, cannot achieve such flexible, curved turns in extremely narrow spaces.

That guy usually flies and lands with wide, sweeping movements.

But Li Zhen's timely braking after crashing into the target and the arc-shaped recoil within a fraction of a millimeter made her look more like a nimble sprite.

"Speed ​​test results: The highest instantaneous speed is Mach 5.7, far exceeding that of ordinary superhumans, but the neural reaction speed can only match the movement state of Mach 3.8."

Bruce analyzed the dynamic trajectory on the screen.

"Your neural responses can't keep up with the speed of the surge; there's a clear adaptation gap."

As soon as she finished speaking, Li Zhen adjusted her posture and started again.

This time, he deliberately slowed down his starting speed, gradually adapting to his body's limits.

As the test progressed, the deviation value on the screen became smaller and smaller. After just ten minutes, he was able to accurately capture all the targets at Mach 5, but every time he made a shot, the target would inevitably be torn to pieces.

Bruce's surprise deepened.

"Their adaptive growth rate is extremely fast, far exceeding that of known superhuman races. Is this a talent of the Witrum people?"

Li Zhen did not answer, but simply stopped what she was doing and waited for the next test.

He knew very well that this ability to adapt quickly was forced out of him during the life-or-death trials on Witrum.

Those who couldn't keep up with the enemy's speed were already corpses.

During the defense test, after Li Zhen took off her shirt, Bruce first activated the high-pressure energy cannon.

The energy beam struck Li Zhen's chest, making a hissing sound, but it didn't even leave a trace of white mark.

Then he acquired an alloy box containing various weapons.

"Next, we'll test penetration of defenses. These weapons all incorporate N metal."

Seeing the puzzled look on Li Zhen's face, Bruce explained.

"N metal originates from the planet Thanagar, Hawkman's home planet. This metal has the properties of anti-gravity, energy conduction, and enhanced penetration. It can interfere with the biofield of most superhumans and even damage divine bodies. It is a rare material in the universe that can penetrate defenses."

A mechanical arm that rose from the ground gripped a long sword infused with N metal and slashed at Li Zhen's arm with all its might.

The moment the blade touched the skin, it made a piercing metallic scraping sound, and a shallow bloodstain appeared on Li Zhen's arm, which then healed at a speed visible to the naked eye.

"The blade can penetrate defenses."

Bruce recorded the data, then operated the robotic arm to switch to a specially made pistol.

"Now testing N-metal bullets."

"Bang!"

Gunshots rang out, and an N-metal bullet hurtled towards Li Zhen's shoulder at high speed.

After the bullet hit the target, it was instantly bounced away, making a small dent in the wall, while only a faint red mark remained on Li Zhen's shoulder, which disappeared in an instant.

"strangeness."

Bruce frowned, his fingertips tapping on the control panel.

"A blade can penetrate defenses, but a bullet can't? Both have the same nitrogen content; the only difference is the contact area and the mode of impact."

He pondered for a moment, a flash of understanding appearing in his eyes.

"Your superpower core may be related to the unique microscopic body structure of the Witrum people. This structure can disperse point-like impacts, but it is difficult to resist linear cutting forces."

This discovery made Bruce even more wary; the Vitrum people's physical structure was far more complex than he had imagined.

But he didn't delve any deeper; he simply took out a sterile syringe and said to Li Zhen.

"A small blood sample needs to be drawn for basic analysis; it will not harm you."

Li Zhen extended her arm without resistance.

With the activation of a switch, the specially made needle tip began to vibrate at a high speed at a frequency invisible to the naked eye, and then still managed to pierce Li Zhen's skin with some effort.

However, the subsequent blood draw process went smoothly.

After the blood was drawn, Li Zhen suddenly spoke.

"The Witrum have an open weakness: sonic weapons."

Bruce was stunned for a moment.

Li Zhen then continued speaking.

"Excessive sound wave energy can interfere with and stimulate our eardrums and brain, and in severe cases, it can lead to loss of body control and inability to fight."

Bruce was silent for a moment, then looked up at him.

"I know you want to test your limits, but the blade and bullet tests are based on safe testing ranges calculated from strength data. The purpose is to understand the boundaries of your abilities, not to harm you."

"Using sonic weapons would directly cause you serious injury, which deviates from the original purpose of the test."

"I need to know where my limits are."

Li Zhen spoke firmly.

"On Witrum, those who do not know their own weaknesses and limits will not survive the first trial."

Bruce shook his head.

"I don't have any sonic weapons on hand. The research and development of such weapons are all in Batman's secret base. If you insist, I can arrange it later, but not now."

Seeing his resolute attitude, Li Zhen stopped pressuring him.
