"Where...where is this?"

Dr. Gero was completely dumbfounded.

Instant Teleportation appearing right before him was one thing, but being silently transported to another place without notice—this kind of technique completely surpassed his realm of understanding.

"I can grant you endless life, restore your youth, bestow upon you an Undying Body, and provide you with a more relaxed research environment."

"If you refuse, the consequence is death."

"Choose one."

Dr. Gero was stunned.

Endless life?

Youth restoration?

Undying Body?

This was practically the ultimate pursuit of humanity.

Even though he had consistently held a firm belief of avenging against Sun Goku, he was nonetheless slightly swayed upon hearing Su Xin’s promise.

But then he quickly reacted.

Anyone can talk big; even if you possess substantial strength and the miraculous technique of Instant Movement, that doesn’t mean you can casually bestow immortality to others.

At this moment, Su Xin shook his head:

"Never mind, I know you won’t believe it. I’ll first grant you a century of life and then talk about it."

Speaking, Su Xin pointed his finger outwards.

Dr. Gero had no time to react, he could only stare blankly as Su Xin’s finger touched his forehead.

In the next moment, he felt a massive surge of heat emerge from within his body, rapidly spreading throughout him; his frail and powerless physique suddenly possessed formidable strength, his muscles firmed up again, his shriveled body began to inflate at a visible speed, like a deflated balloon being rapidly filled.

More importantly.

A seemingly endless power was welling up from deep within his body. Although this power was not exaggerated and should be akin to the average person, to the aging Dr. Gero, this power was nothing short of a miracle.

He couldn’t help but lift his arm to take a look.

Sure enough, his formerly shrunken limbs, sagging skin, had rejuvenated to the strong and robust state of his youth, his skin becoming quite taut.

He carefully examined his body, finally confirming that he truly had become young once more.

"This...this..."

Dr. Gero was completely dumbfounded.

A casual touch of the finger could rejuvenate his aging body; this technique utterly shattered his limits of imagination.

"This...this is the way of the gods!"

Dr. Gero, face full of excitement, looked at Su Xin and said, "I am willing to follow you."

But then his tone shifted.

"However, I have one condition: I want revenge, I want to kill Sun Goku, I want to witness his death with my own eyes."

Su Xin replied calmly, "I quite admire Sun Goku, so I won’t help you kill him. But if you want to do it yourself, I won’t stop you. Whether you choose to proceed with your research on androids personally or use them, it’s all up to you."

Dr. Gero thought for a moment, then nodded and said:

"Alright, then I am willing to follow you."

Su Xin pointed his finger again, granting Dr. Gero twenty Life Talismans and completely informing him of their effects.

Regarding his lifespan, Su Xin had just given him a hundred years, so there was no need to grant more in the short term.

As a powerful being in the Human Immortal Realm, even relying on cultivation alone, Su Xin has a lifespan of one hundred thousand years, coupled with his peerlessly strong physical body, his lifespan surpassed a billion years as his body continued to transform over the years.

Moreover, he accidentally caused the deaths of millions previously, granting him an additional two hundred million years.

His current lifespan exceeds three hundred million years.

The key is, even if his lifespan is exhausted, under the effect of the Unyielding King, he won’t age, nor will he die due to the depletion of lifespan.

Basically, the so-called lifespan is nothing but a meaningless series of numbers for him.

The millennium lifespan consumed to recruit Dr. Gero was nothing significant to him.

The investment to enlist an unreasonable top-tier scientist like Dr. Gero was undoubtedly a highly profitable transaction for Su Xin.

Subsequently, Su Xin used Telekinesis to transfer the entire underground base along with the surrounding land into a small world, specially crafted an experimental area for Dr. Gero.

As for the energy and various supplies needed for the experiments, he allowed Dr. Gero to manage by letting androids purchase a large batch in advance, ensuring they wouldn’t run short on materials in the short run.

It must be said that Dr. Gero is indeed a top scientist in the field of bioengineering, not only capable of transforming humans into powerful cyborgs but also able to integrate the genetic strengths of various cosmic races to create new organisms, qualifying as a top scientist in the Dragon Ball Universe and many other universes.

Within his base, besides the androids being cultivated and transformed, there are some used as assistants.

Thus.

Even if he is alone, he can effortlessly control the progress in the entire experimental base.

With Su Xin’s support, he doesn’t need to worry about exposure or the risks of test subjects losing control.

He can experiment to his heart’s content.

Focusing more energy on enhancing the power of test subjects.

It’s worth noting that in Dr. Gero’s past experimental processes, many test subjects weren’t abandoned due to power issues, but mostly due to character issues, marked as failures.

Such as the former friend of Sun Goku when young, Number 8, and most androids before Number 15, possessing autonomous consciousness.
