Zhang Donglai nodded approvingly.

This Gandalf was indeed excessively calm.

He asked himself, if it were him lying inside that glass container, he would definitely feel somewhat nervous inside.

He really wondered what kind of Clan this kid was born into.

And what kind of experiences he had.

To be able to cultivate such a resilient mental state.

On the side, a trace of morbid excitement had already appeared on the face of Professor Li, the old professor.

He rubbed his hands, a fanatical light flashing in his turbid eyes.

"The current intensity is merely 1.0."

"Next, I am going to increase the dosage!"

He looked like he was showing off his proudest work.

"Let us see together just where the limit of this Student Gandalf is!"

Principal Chen heard this and hurriedly reminded him from the side.

"Professor Li, you had better take it easy."

"Student Gandalf is the future hope of our Great Xia Nation after all, absolutely nothing can go wrong."

Professor Li waved his hand dismissively.

"Rest assured, I know what I am doing."

As he spoke, he walked over to the console and pressed another button without the slightest hesitation.

Hum——!

Inside the several transparent pipes connected to the container, the dark blue liquid began to flow again.

This time, the injected dosage was obviously much larger than before.

The color of the liquid inside the container became even deeper, and even somewhat viscous.

The bubbles rolled and churned even more violently.

Professor Li's gaze was locked tightly onto the curve on the monitor that represented Gandalf's Mental Strength fluctuations.

He was a bit dumbfounded.

"How... how is there still no emotional fluctuation?!"

He rubbed his eyes in disbelief.

That green curve remained as flat as a horizontal line, without the slightest undulation.

"Has this guy's Mental Strength already reached such a degree?"

Chen Lanxin, standing nearby, chimed in to explain.

"Although the intensity value only increased by 0.5."

"However, for the participant inside the container, the pressure to be endured on the mental level increases exponentially."

She glanced at the calm curve, a trace of surprise also flashing in her eyes.

"When we previously tested other students, an intensity of 1.5 was already the limit for the vast majority of people."

"Almost no one can sustain themselves under this intensity for too long."

Zhang Donglai looked at the motionless figure completely submerged by the blue liquid inside the container, his brows tightly locked.

"Could it be that... the testing instrument is broken?"

Professor Li immediately shook his head, his tone resolute.

"Impossible! I debugged this instrument with my own hands, it absolutely will not have problems!"

He looked at the monitor, and for the first time, genuine shock was revealed in his turbid eyes.

"It is this Gandalf's willpower... far exceeding ordinary people!"

"He is the young man with the most terrifying willpower I have ever seen in my life, bar none!"

On Zhang Donglai's face, the look of worry grew even heavier.

"He has been in the container for almost half an hour, and hasn't even moved a bit."

"Could it be that... he passed out long ago?"

However, right as his voice fell.

Hum!

Inside that huge metal container, a dazzling golden pillar of light abruptly soared into the sky!

Even separated by that dark blue liquid and the thick specially-made glass, the light remained dazzling.

Gandalf's Level reached Level 35!

Zhou Huai nodded with satisfaction.

He had to admit, this leveling-up method was indeed fast enough.

Having soaked for less than half an hour, he had already risen by one level.

At this speed, rising to level forty within half a month really wasn't much of a difficult task.

Just at this moment.

Gandalf slowly opened his eyes.

His gaze pierced through the dark blue liquid and landed on the three dumbfounded faces behind the console.

Immediately afterward, he raised his hand and extended a single finger upward.

Zhang Donglai looked at Gandalf's action and was somewhat dazed.

"He... what does he mean by this?"

Chen Lanxin on the side pushed the glasses on the bridge of her nose and softly speculated.

"Judging by the gesture, it should be that he feels the intensity is not enough."

"He wants us to... continue increasing the intensity."

Zhang Donglai: "..."

Principal Chen: "..."

The two looked at each other in dismay, both seeing a trace of an emotion called "outrageous" in each other's eyes.

Zhang Donglai wildly complained in his heart.

Is this kid even human?

When other people reach an intensity of 1.5, it is just like undergoing torture.

Look at him instead, not only does he not feel pain, but he actually takes the initiative to request an increase in dosage?

This is no longer a matter of having a firm willpower.

This is simply a monster without a sense of pain!

Seeing Gandalf's gesture, Professor Li's old face was flushed red with excitement.

He didn't have any hesitation at all, taking a step forward and rushing to the front of the console.

"Good! Good! Good!"

He said three good words in a row, as if he had discovered an unpolished piece of peerless jade.

"Since you want it, then I will give it to you!"

He extended his slightly trembling hand and directly pushed the intensity gear to the position of 【2.0】!

Boom——!

More blue liquid was injected into the container.

The liquid inside the entire container had already become as thick as un-dissolvable ink.

Looking from the outside, one could only barely see a blurry humanoid outline looming within it.

Outside the laboratory, the gazes of the four people once again gathered uniformly onto the monitor.

Everyone held their breath, staring without blinking at the curve representing Gandalf's Mental Strength fluctuations.

One second.

Two seconds.

Ten seconds.

That green curve remained as calm as stagnant water, without stirring up the slightest ripple.

Dead silence.

The entire laboratory fell into a death-like silence at this moment.

You could hear a pin drop.

On Professor Li's forehead, fine beads of sweat had already oozed out.

He widened his eyes, his mouth slightly open, and the expression on his face was an incredulity that could not be described with words.

"This... how is this possible?"

He muttered to himself, his voice even trembling.

"An intensity of 2.0 is already the theoretical limit this instrument can reach!"

"Even those military special forces soldiers who have experienced countless life-and-death tests, under this intensity, their minds would completely collapse within three seconds!"

"Why... why does he still not have the slightest emotional fluctuation?!"

Professor Li felt his worldview receive an unprecedentedly fierce impact at this moment.

"Unless... unless his brain is already dead."

"Otherwise, how could there possibly be someone without even a shred of emotional fluctuation?!"

Chen Lanxin, standing behind the crowd, had her beautiful eyes hidden behind her lenses as she looked with great interest at the blurry outline inside the container.

It is truly getting more and more interesting.

She suddenly remembered what Zuo Daolin had said to her not long ago.

"That young man named Gandalf is very abnormal."

"Is there really no soul inside his body at all."

At that time, Chen Lanxin had scoffed at this.

But looking at it now...

Zuo Daolin's judgment might be correct.

A shell without a soul?

Gandalf, what kind of monster are you really?

She really wanted to dissect him open and take a look.

To see what kind of structure was actually inside his brain.

Just at this moment.

"Tap, tap."

Two crisp knocking sounds came from the thick specially-made glass, breaking the dead silence of the laboratory.

Everyone's gazes were attracted over once again.

Only to see that blurry outline inside the container moving once more.

Just when everyone thought whether he finally couldn't endure it anymore.

That outline, once again, slowly extended a single finger.

It was still that same posture.

It was still pointing upwards.

Continue.

Step up the intensity.
