Xingtie: My silly online friend is actually a raccoon!

When the two returned to the living room, Bella and Celine were no longer there; they had probably gone to Luze's room to start a live stream.

Xilin's live streaming schedule has become more and more regular recently, and her number of fans has steadily increased. The money she has earned is already enough to cover her daily expenses.

This made Lu Ze very happy; his child had finally become independent.

Black Tower remained quietly seated on the sofa, flipping through the world history book he hadn't finished reading yet.

When she read the section on the modern industrial revolution, she raised her eyebrows slightly, clearly quite surprised by how quickly this civilization had jumped from the steam age to artificial intelligence in just a few hundred years.

"Black Tower..." Lu Ze was about to speak.

As if predicting what he was about to say, Black Tower handed him a sheet of paper without even looking up.

Lu Ze took a look and his lips twitched.

This is clearly a blank page torn from the last page of world history. The place that should have been printed with copyright information and the publisher's logo is now torn crookedly.

A string of complex formulas, so intricate they made his brain spin, was written in the blank space.

He was someone who had developed more than 20% of his brain capacity, but the complexity of this formula still caused his brain to instinctively issue an overload warning.

Zhao Deshan quickly came over, staring excitedly at the string of formulas, and asked:

"This is……"

He couldn't understand a single word either. Having seen countless people, he knew all too well that this genius lady wouldn't just produce a useless formula for no reason.

When someone like Black Tower makes a move, they either don't give anything at all, or if they do, it's something far beyond what's available in this era.

"A universal formula, applicable to the nuclear energy systems of all inferior civilizations." Black Tower turned a page of his book without even looking up.

It's not that she doesn't understand social etiquette; having lived for so many years, she's seen it all.

She's just too lazy to cater to people she's not interested in.

However, she also had to consider Lu Ze's feelings. Although the little guy was annoying, he was, at least, her owner now.

Her status was equivalent to that of Estádio.

She couldn't let him be caught in the middle and put in an awkward position.

So she casually wrote down this formula, though it wouldn't necessarily allow the civilization to leapfrog to a higher level.

But if we can fully understand this formula, it will at least prevent this planet from being troubled by energy shortages for a long time to come.

"Is it possible to achieve controlled nuclear fusion?" Zhao Deshan's voice trembled slightly.

"Using the formula, with your current materials science, you can perfectly achieve civilian controlled nuclear fusion." Black Tower's gaze remained on the pages, his fingertips turning another page.

After listening, Zhao Deshan snatched the paper full of formulas from Lu Ze's hand, carefully folded it in half and then in half again, before putting it into the inside pocket of his underwear.

He even pressed his hand firmly against his pocket, feeling the outline of the thin paper through the fabric, as if afraid it would slip away.

"Why don't you take a picture and send it to the station for filing first?" Lu Ze found it amusing to see him acting like he was protecting a precious treasure.

The dignified district chief of the Countermeasures Bureau acts like a child clinging to his New Year's money.

Zhao Deshan glared at him and said righteously and sternly:

"What do you know, kid! Can this thing be transmitted over the internet?"

What if the data is intercepted by hackers from an enemy country? What if the data is corrupted during transmission? The safest way is to carry it physically without any intermediaries.

"Fine, do whatever you want." Lu Ze shrugged.

Zhao Deshan ignored him and turned to walk towards the entrance.

"I'll take my leave now. Ms. Black Tower, I'll personally bring your identification documents later."

After saying that, he took out his phone and made a call, his voice very low.

Lu Ze vaguely heard Old Zhao say on the phone that he would transfer a regiment of soldiers to escort him back to the bureau.

That's an exaggeration.

Lu Ze called out with a smile to the figure standing at the door.

"Old Zhao, didn't you say you'd invite me for tea?"

Without turning his head, Zhao Deshan roared out in a powerful voice:

"Get lost, you brat!"
