Marvel: My Sign-in System

The space base is enormous, but there isn't much to do. The four younger ones are just wandering around with the others. The interior structure and decorations are quite different from the usual cold machinery; many warm elements have been added, making it brighter. Sunlight even reaches the upper levels during the day, illuminating the area.

If Dreykov could see his base transformed like this, he'd probably be angry enough to die all over again.

After exploring for a while, everyone gathered on the top platform of the base, which felt like a huge playground. Nearby, there was a theater, a fountain with rocks, and a swimming pool. An oval glass ceiling above blocked harsh ultraviolet rays and could automatically adjust sunlight, so the top floor stayed bright without the need for artificial lights.

Without hesitation, young Clarice opened a portal and brought out swimsuits, snacks, and other items from the manor. Those who wanted to swim swam, others enjoyed fruits, and some browsed the internet on their laptops. It was truly a leisurely atmosphere, so much so that I forgot to practice.

On the other side of the vast hall, Yelena, Melina, and Alexei began injecting the super gene serum. As soon as the serum entered their bodies, an astonishing transformation occurred. Their bones, cells, organs, and blood began to change in remarkable ways. Past injuries, even removed organs, began healing. It was as if they were soaking in warm spring water.

A powerful energy surged within, making the world seem more vibrant. My senses—smell, vision, and hearing—felt sharper and enhanced. It was an incredible sensation.

Yelena and Melina's heights shifted slightly as their bodies adjusted to an ideal form. Their pores became finer, their skin turned fairer and smoother, and their overall aura changed slightly, though their appearances remained mostly the same. Alexei, however, was transformed differently. His body fat melted away, revealing a massively muscular physique. Perhaps due to his prior injection with the super-soldier serum and his already large frame, his muscles looked even more intimidating.

He resembled a devilishly muscular figure, his veins bulging under his skin. But Alexei loved his new form. To him, muscles symbolized strength and power.

The strong Eastern European man happily started doing aerobics, raising his muscular arms and flexing to catch Melina's attention. She couldn't help but roll her eyes at him. This guy is just a big kid.

Yelena ignored their interaction, focused on adapting to her transformed body. She crouched slightly and then pushed off. Bang! With a massive burst of power, she shot upward like a rocket, nearly hitting the ceiling in an instant. Fortunately, she instinctively flipped and landed in a crouch on the ceiling. This brief moment of pause defied normal human coordination and control.

With a cheer and a little shout, Yelena jumped down from over ten meters up. "Wow! So this is why Natasha is so strong? It's incredible~!" As she spoke, she casually began a set of combat moves, each punch and kick accompanied by the whoosh of air. Her movements were packed with speed and power; she looked capable of taking down the most fearsome land predator.

Melina turned to Alexei, exclaiming, "It's incredible, he's amazing!" She added, "This super gene serum is terrifying."

As she spoke, her thoughts went deeper. Natasha, Sergei, and a dozen others, along with herself, Yelena, and Alexei, now all had access to this serum. This meant that Leon might have mastered the technology to create the serum reliably. If he wanted, he could form a powerful army of super soldiers.

With such formidable combat skills, Melina was sure that Leon could easily seize control of the world. The destructive power of soldiers at this level was terrifying; it would only be a matter of time before they could disintegrate and destroy entire nations.

But Melina knew Leon well—he wasn't the type to have such ambitions. In fact, his goals were far beyond mere world domination. With the advanced technology he had revealed, Melina had begun to suspect something even grander.

This thought both horrified and thrilled her. Maybe, by following Leon, she, Yelena, and Alexei could witness a wider, unimaginable world.

Yelena, meanwhile, wasn't thinking about any of this. Her focus was on finding Natasha. In the past, Natasha had been so strong that Yelena had to stay meek and obedient, like a quail.

But now, just as Yelena was imagining ways to tease Natasha, the metal door automatically opened in the distance. Natasha walked in, holding several glass tubes in her hand. Seeing her, Yelena's eyes widened, ready to provoke her, but Natasha didn't give her the chance to speak first.

"You've been injected with the super gene serum and need plenty of nutrients to meet your energy needs," Natasha said, handing over the nutrient solutions.

Melina, Yelena, and Alexei took the nutrient solutions and drank without hesitation. They tasted sweet and tangy, quite delicious. As Yelena finished hers, she felt a satisfying fullness in every cell of her body.

Unable to contain herself, Yelena eagerly shouted to Natasha, "I've had the serum too! Let's see who the real winner is this time!"

Natasha shook her head, her tone playfully teasing. "Trust me, you're still not quite there yet."

Yelena bristled, ready to argue, but as soon as she met Natasha's gaze, a powerful, intimidating aura seemed to radiate from her. Under this fierce and commanding presence, Yelena instantly quieted. In Natasha's familiar, bright eyes, she felt an overwhelming momentum—a force like a tidal wave crashing toward her.

Yelena instinctively softened, feeling a newfound respect. She stood still, no longer as defiant as before.
