He just broke up with his girlfriend and is already living with the devilish rich girl.

Chapter 210 is truly nostalgic.

"Why are you in such a hurry?"

The old man told Tao Ye not to rush, and continued his work at a steady pace.

Like a craftsman assembling a precision clock.

He carefully loaded a core, which was flashing an unstable red light and covered with complex circuitry, into the reserved slot in the North Star's chest cavity.

"Click".

With a soft click, the core connection was successfully established.

As the old man closed Polaris's chest again, he said to him, "This thing is called the Alpha Overload Amplification Core. It's still a semi-finished experimental product, and its power can only be increased to 80% at most."

"Any higher and there's a risk of self-destruction, but it should be enough for you to turn that space down there upside down."

"...Are you sure it's okay? Can you just install the semi-finished product for me?"

When faced with the question about Polaris, Old Xu gave a cold laugh.

"Kid, scientific experiments mean that innovation and breakthroughs are needed again and again. If a device is not used in actual combat, it will always be a half-finished product."

Polaris didn't say anything more.

You can actually feel it too.

Old Xu even installed the unfinished core onto himself.

That proves that even he might find the following thing very troublesome.

"All done." The old man patted the dust off his hands and looked at his work with satisfaction.

"Now, you may go in."

"So, old man," Tao Ye said, scratching his head, looking puzzled.

"You've talked for so long, how are we supposed to get in? It's pitch black down there, won't we just fall and die?"

The old man ignored her and instead turned his gaze to Zheng Yueyao, who had remained silent.

"Didn't you already bring the keys?"

Zheng Yueyao paused for a moment, then subconsciously gripped the hilt of the knife at her waist, a hint of uncertainty flashing in her eyes.

She was afraid, afraid that she couldn't do it.

I'm afraid I'll let everyone down.

"Heh." Old Xu saw her hesitation and sneered.

"If it weren't for that kid Bai Ziheng intervening at the end, you probably would have already killed that monster Luo Yao in the end."

"Hey! Don't call her a monster!"

Tao Ye immediately retorted with dissatisfaction.

"In short, that's what I wanted to say."

The old man ignored Tao Ye's protest and continued speaking to Zheng Yueyao.

"Your name has already been jointly submitted by me and Director Lin."

"After this incident, as long as you are alive, you will become a new S-rank operator."

"What, are you going to tell me now that you're not ready to take on this responsibility?"

Zheng Yueyao gripped the hilt of the long sword at her waist tightly, her knuckles turning slightly white from the force.

She thought of her younger brother, Zheng Xingguang, who was still in the hospital, his life hanging in the balance.

He couldn't let these monsters continue to hurt him.

And... Mr. Bai...

Perhaps, Mr. Bai will never even glance at him until the very end.

In his world, he might just be an insignificant passerby he met by chance.

No, not a stranger, but my benefactor...

but……

Even so, I still want you to see it.

Seeing my growth.

I want to tell you loudly...

I can also become someone who can protect everyone and stand shoulder to shoulder with you!

Therefore, we must not stop here!

"Are you ready?"

The old man asked again, his voice not loud, but it struck Zheng Yueyao's heart like a heavy hammer.

"I'm ready."

This time, Zheng Yueyao's answer was firm and resolute.

Zhou Xuetong stepped forward and gently patted Zheng Yueyao's shoulder, her tone unusually gentle.

"Don't be nervous. I know your abilities, and you should be well aware of them yourself."

"Breaking through that barrier is not a problem for you."

"You only need to trust your own eyes and the knife in your hand."

"Don't relax too much, after all, you only get one chance."

The old man spoke again, his tone becoming extremely serious.

"If this spatial barrier in Youdu is not cleaved open instantly, or if the opening is not large enough, your falling bodies will crash directly into the barrier."

"At that time, death will be certain, with no chance of escaping."

"Hey! Grandpa! Can you please stop putting so much psychological pressure on her!"

Tao Ye, who was listening from the side, was almost going crazy.

"It's okay."

Zheng Yueyao shook her head, her eyes now incredibly clear.

"It is precisely because I know its importance that I will never fail."

Looking into Zheng Yueyao's eyes, which were no longer filled with confusion, the old man nodded in satisfaction.

He raised his hand and snapped his fingers.

Then, a drone flew in from high altitude and dropped a silver metal box in front of everyone.

"Judging from your expression, it seems like everything's fine now. I'll leave this to you."

"This is……?"

The box opened automatically, revealing a long, dark red sword with a mechanical aesthetic.

The blade was covered with blood-red patterns.

"This is a knife I specially crafted for you based on your supernatural ability, Death Mark, called Blood Fiend."

"It can resonate deeply with your nervous system, amplify your perception, and allow you to see more clearly and cut through everything, tangible or intangible, along the traces that represent 'death'."

Zheng Yueyao stared at the knife in shock, then looked at the old man.

"When...when did you start preparing?"

"From the first time you showed those eyes at the Special Administration Bureau, I knew that one day you would reach or even surpass your father's achievements."

"To become a true S-rank operator."

"The purpose of our scientific research institute is to support all operators, especially S-rank operators like you."

"Therefore, we conducted extensive research on you beforehand, collecting combat data from every mission report you submitted, and even..."

He pointed at the knife.

"The blade of this knife is infused with the blood we collected from each time you were injured."

"You could say it has become a continuation of your life."

Hold it.

Zheng Yueyao reached out and slowly grasped the hilt of the knife.

The moment she touched the hilt of the knife, an indescribable feeling of being connected by blood instantly spread throughout her body!

She could even feel that her nerves were connected to the internal circuitry of the knife.

Her heartbeat seemed to be in sync with the knife.

"Very good." The old man looked at her and smiled.

"If your strength and will are not firm enough, you will now be devoured by the massive death information contained in this Blood Fiend, turning into a madman who only knows how to kill."

"What?!"

Upon hearing this, Tao Ye's anger flared up again.

"You mean, until just now, you were still testing her?! What were you going to do if she was harmed by this knife?!"

"Not really."

The old man answered expressionlessly.

"Then let's abandon Youdu and liberate the other areas first. We don't have time to waste more resources on a failed experiment."

"You old geezer!"

Tao Ye was so angry that she wanted to curse, but was stopped by Polaris who was standing next to her.

"Let's get down to business first. You've known Old Xu for a while now."

"That's why I'm so fed up with you people from the Special Administration Bureau!" Tao Ye shook off his hand.

"I know," Polaris nodded.

"Most of the S-rank operators who are currently on the sidelines are actually just like you."

"This is also why we almost never hold regular positions at the Special Administration."

"But the world is facing an unprecedented crisis, and there is no time to dwell on personal grudges and ideological conflicts."

"At least for now, our goal is the same as theirs: to stop the mirage demons and save the world."

Although Tao Ye was still very unhappy, he didn't say anything more.

"Have you finished discussing this?"

Old Xu urged impatiently.

"The spatial coordinates of the Netherworld below may shift at any time due to energy decay."

"If we miss this opportunity, I can't guarantee that we won't be able to observe it again."

Tao Ye clicked his tongue in dissatisfaction, but still walked to the edge of the cliff like the others, ready to go.

Zheng Yueyao took a deep breath, gripping the Blood Fiend sword that seemed to be one with her, and stood at the very edge of the cliff, looking down into the deep, boundless darkness.

Focus your attention... Concentrate...

In that instant, her world changed.

Countless black markings, like a spider web, representing "death."

They twist and turn, like the branches of a gigantic, withered tree that has grown from the depths of hell.

There are...so many...

"Is it possible?" Zhou Xuetong asked softly, standing beside her.

"no problem."

Zheng Yueyao smiled, a smile full of confidence and determination.

Xiao Guang... Dad.

And... Mr. Bai.

I will succeed.

She exhaled her last breath and slowly gripped the hilt of the Blood Fiend sword.
