Natasha rolled her eyes, then turned to ask Li Da about the whereabouts of the others.

Li Da didn't hide it, answering calmly in front of everyone: "They are scattered everywhere, specifically hunting down dark races."

"It seems a lot of major events have happened these past few days, and I had no idea at all."

"Indeed quite a lot."

"However, Wanda mentioned that you prepared a surprise for me, and I'm looking forward to it." Natasha's eyes lit up, her red lips curved slightly, and her exquisitely peerless face was full of curiosity and desire.

"It's a good thing, I'll reveal it later."

Li Da smiled, not revealing it immediately, and instead looked at Melina: "Natasha mentioned that you once participated in some of Dreykov's confidential R&D projects."

"That's right, Dreykov trusted me deeply." Melina nodded slightly, responding with a calm expression.

That so-called "trust" was built on the lives of countless generations of people.

The blood on Dreykov's hands was too much for even himself to count.

Those children who couldn't endure the harsh trials in the training ground and ultimately died were all sacrifices sent away by his own hands.

Melina would rather have never obtained this trust.

Compared to Natasha's resolute courage in fleeing back then, she always felt she was cowardly.

Every time she thought of Natasha successfully escaping, the sense of shame gnawed at her heart like a venomous snake.

But now, everything was different.

That demon who treated people as consumables was completely dead and gone.

The nightmare that had weighed on her heart for many years dissipated, and she finally dared to face her disgraceful past.

Li Da's mouth curled up slightly, his gaze falling on Natasha.

Natasha understood, handing a tablet computer she brought from home to Melina.

Melina took the device, her fingertips sliding across the screen, and when she saw those confidential files, her pupils shrank slightly.

"It seems you really have taken over his scientific research team."

She raised her head, her tone complex: "Sky Fortress Project, to what step has the progress reached?"

Li Da didn't hide it, nodding frankly: "Madam, I need someone to keep an eye on this group of madmen. And you seem to have had a lot of intersections with them."

That's right, it was the Sky Fortress.

After previously using Wanda's Chaos Magic to deal with Dreykov, Li Da logically swallowed the opponent's gray assets and scientific research team.

After getting the sky blade 7 technology from the check-in reward, he had Keira begin optimizing the architecture of the Sky Fortress.

Facing the sky blade 7 technology, which surpassed Earth civilization by countless epochs, building such an aerial base was simply as easy as turning over a hand.

The construction period originally expected to take four or five years was forcibly compressed to within a year and a half.

Even shorter.

This wasn't just to build a floating city.

It was the foundation for future force expansion.

sky blade 7 was an absolute secret, Li Da's trump card, and must never have any connection with Wanda and others.

Even if the Meilu Heavenly Court was checked-in in the future, he would draw a clear line with Earth forces.

His layout was very clear: taking Earth as a springboard, overtly establishing a divine kingdom similar to Asgard to attract attention.

Secretly, the Angel Civilization maintained transcendence and mystery, developing alone.

The two behemoths that seemed unrelated were actually both in his hands alone.

Imagine that one day in the future, a brand-new divine kingdom would rise on the cosmic stage.

At the same time, the Angel Civilization armed with sky blade 7 would quietly descend.

As long as the check-in system was powerful enough to perfect the Angel Civilization to the extreme, the next target would be heaven.

Those guys occupying the resources of the heavenly dimension would sooner or later be replaced by the Angel Legion.

This was his true trump card.

Ever since sky blade 7 appeared, Li Da's planning for the future had already been overturned and restarted.

He intended to let these secrets rot in his belly.

Even to the closest people like Natasha and Wanda, he wouldn't reveal a single bit.

After all, when a real crisis came, these trump cards would be the key to saving lives.

Survival rule number one: Lay low.

In this chaotic era, if you didn't hide yourself in the shadows to act like a sly player, tomorrow you might become a corpse because of some unknown causality weapon.

Caution had already become Li Da's physiological instinct, carved into his bone marrow.

Melina didn't know Li Da's true intention.

When Li Da fully handed over the management rights of that scientific research team to her, she only felt a weighty trust.

In her eyes, this group of people left behind by Dreykov was simply an invaluable treasure.

That was an elite team built by spending countless years and burning astronomical amounts of money.

Even the world's top financial tycoons today probably couldn't produce such resources.

Yet Li Da just handed it over to her so casually.

Melina took a deep breath, suppressing the shock in her heart, and nodded solemnly: "I will keep a good eye on this team."

"Very good."

Li Da remained calm on the surface, but his tone carried a bit of casualness: "It won't be long before the'Sky Fortress' becomes a trump card in our hands."

His words turned, seeming to mention it casually: "However, regarding a new technology of that team, there are some details you need to pay attention to."

"New technology?"

The surrounding air froze a bit instantly, and everyone looked at each other.

"That's right."

Li Da's gaze swept across the audience, throwing out a blockbuster: "Deep inside a secret database of Hydra, I dug up a set of unfinished blueprints. The theme is —— Artificial Intelligence."

Artificial Intelligence?!

These words exploded like a thunderclap in everyone's mind.

"According to the records, if it can be perfected, this technology will directly crush the current global technology level."

Li Da had a solemn expression, analyzing methodically: "More importantly, it will become the brain of the'Sky Fortress'. With AI assistance, our combat power will undergo a qualitative change."

He was lying.

What high-end general artificial intelligence was there?

The so-called "core technology" was just changing the shell of the Keira system on sky blade 7.

To be honest, with the current computing power, building an artificial intelligence by himself was simply as easy as turning over a hand, and he could even make it more perfect than Tony Stark's Jarvis.

But would that be interesting?

Of course it couldn't compare to Keira.

Moreover, using the gimmick of "artificial intelligence" as a shield couldn't be better.

In the future, if he brought out any other epoch-surpassing black technologies, there would be no need to explain the principles at all.

Just push it to "AI automatic optimization", who would dare to question a supercomputer with self-evolution capabilities?

"I understand."

Melina quickly recovered from the shock, her brows slightly furrowed, and raised a realistic question: "But technology is technology, the laws of physics are right there."

"If the Sky Fortress wants to maintain long-term hovering, it must solve the energy problem."

"The existing engine efficiency is too low, fuel consumption is a bottomless pit, and this speed of burning money is something we cannot afford."

Li Da nodded.

What Dreykov left behind was indeed a massive weapon, but in terms of energy, it was still a sieve.

Relying on turbines and anti-gravity to forcibly take off, the annual maintenance and energy fees were enough to bankrupt any wealthy person.

For Li Da's current asset status, this was also a huge burden.

Just as the atmosphere became slightly stagnant, Natasha, who had been silent all along, suddenly spoke.

Her voice wasn't loud, but it was like a needle puncturing a balloon.

"Actually, there is a ready-made solution."

Natasha's eyes flickered slightly, as if recalling something: "Inside Stark Industries, there is a super-large Arc Reactor prototype."

"Its output power is extremely terrifying, theoretically enough to support the Sky Fortress for long-distance Flight."

Speaking of this, she paused, her tone becoming subtle.

"The problem is that it is the highest secret of the Stark Family. Getting it out won't be a small difficulty."
