Invincible! This person has lived for a billion years

Amy's mind was simple,whatever William said was the truth.

Defeat the monsters, and you get the treasures.

Amy had played some mobile games before, so she found this concept quite straightforward.

In fact, she thought it was only natural.

Carrying the Sword of the Abyssal Guardian, Amy walked towards the towering structure ahead.

Once she entered, William disappeared from the spot.

As for Walker, William wasn't worried about him. The robots wouldn't kill him, but these three days wouldn't be easy for him.

Injury was inevitable.

The stronger he became, the stronger the robots would be.

William needed to constantly control the robots, but he didn't need to be physically present all the time.

As Amy walked through the grand doors of the tower and down a metallic corridor, she saw a mysterious figure wearing a mask, his back to her.

Beside the mysterious person was a two-foot-tall mechanical dog, and behind him stood a divine tree laden with Red Flame Fruits.

Transplanting a Red Flame Fruit tree into the tower was no difficult task for William.

Amy was invited in by him, so naturally, the Red Flame Fruit tree was supposed to be there.

"Mr. Johnson really didn't lie to me," Amy's eyes landed on the Red Flame Fruit tree, her eyes sparkling with excitement.

"Little girl, you want to pick the fruits here? You'll have to defeat this little dog first."

William slowly walked towards the second floor, leaving only the mechanical dog and Amy to face off.

Amy's strength was not weak now,the mechanical dog was originally the guardian of the tower. In terms of power, it had at most the strength of a high-level Soulmancer.

For Amy, the fight would definitely not be difficult.

"What little dog?" Amy stared at the mechanical dog, her eyes filled with curiosity.

This kid didn't look very formidable.

"Stupid human child!!" the mechanical dog barked out, shooting two red lasers from its eyes.

Amy raised her sword with both hands, easily blocking the lasers.

"Little dog!" Amy squinted and smiled, then swung her hand through the air, delivering a slap towards the mechanical dog.

Her tender hand transformed into a huge palm that grabbed the mechanical dog.

"Little dog! You need to behave!" Amy had learned more than just swordsmanship from the two high-ranking god-kings,she had also picked up various divine techniques.

Dealing with a mechanical dog was a piece of cake, wasn't it?

"Woof woof!" The mechanical dog couldn't move at all, completely under Amy's control.

"Noble human child, unit 1138 has been defeated and is willing to serve you."

It was over in a second!

Defeated with just one move, without any suspense.

Amy was even ready to use her lightning magic.

It seems there was no need now.

"That masked weirdo is..." After seeing the masked William for the first time, Amy felt that this figure seemed familiar. Although William had deliberately changed his voice, Amy still felt...

The masked man was Mr. Johnson.

It seems Mr. Johnson was just playing with her.

Even William hadn't expected that Amy, this supposedly foolish little girl, would figure this out.

He began setting up a powerful magic circle on the second floor.

And the treasures on the second floor were various methods for setting up powerful magic circles.

To contend with the powerful Mutated creatures, human physical strength often falls short compared to various powerful magic circles.

Although these powerful magic circles were formidable, they were not so easy to learn.

William made this knowledge public, and the rest was up to the humans' ability to comprehend it.

Perhaps some could master these powerful magic circles and use them to resist the Mutated creatures.

Amy picked all the Red Flame Fruits from the tree and stored them in the storage bracelet given to her by the sea god Poseidon, quickly taking the mechanical dog with her to the second floor.

William stood there and said, "If you can get through these defensive magic circles, the secret manuals on how to set them up will also be yours."

"Alright!" Amy, hearing that it was about defensive magic circles, was not afraid.

Just defensive magic circles, after all. Her two masters had also tailored powerful magic circles for her before.

She felt she could easily get through this defensive magic circle just like she had bullied the mechanical dog earlier.

William, having said his piece, didn't wait for her and went up to the third floor.

The third floor contained various weapons, and if Amy could take all these items back, it would surely enhance the overall combat power of humanity.

As for the fourth floor, it housed the future chips that originally existed in this space.

The fifth floor contained the secret techniques for becoming a Soulmancer, prepared by William...

William indeed planned to help humanity,he was on the side of humans.

But whether some things could be obtained depended on Amy's strength.

Perhaps if Amy couldn't make it this time, they would have to call stronger humans to try.

Amy had already enjoyed plenty of good things from William,naturally, the items upstairs wouldn't be given away easily.

What would happen if that became a habit?

If everything was simply handed to Amy, it would be no different than William using his mind to wipe out all the Mutated creatures.

On the second floor, Amy initially thought she could easily break through the defensive magic circle, especially since she had managed to get through the defensive magic circle laid down by Poseidon before, although it had taken quite some time.

However, once she entered the defensive magic circle, she found it to be even more intricate than those set up by her two masters.

If not for the Sword of the Abyssal Guardian in her hand and her resilient willpower, she might have been slain by the attack triggered by the defensive magic circle with her very first step forward.

Time ticked by, and three days, neither long nor short, passed.

Walker had also stubbornly survived and was now walking towards the high tower with a robot in tow.

William sat next to a stone under the tower, playing games on his smartphone.

Upon seeing William, Walker couldn't help but frown. "William, where's Amy?"

William pointed towards the grand doors of the tower and smiled, "She went inside."

Walker pondered for a moment, "Why didn't you go in?"

"I was waiting for you," William said as if it were the most obvious thing.

"You're okay with her going in alone?"

"Why wouldn't I be?" William chuckled. "Amy's swordsmanship is incredible,what danger could she possibly be in?"

"You're really laid-back," Walker laughed. "Now that I'm here, let's go in!"

The robot now closely followed three steps behind Walker.

"I'd rather not go in,I might hold you back," William said, clearly planning to continue slacking off.

"Get in!!" Walker glared at him. "You're still trying to slack off, huh? Don't think I don't know you've been hiding your true strength. You're at least at the Demi-God level."

"When you, Amy, and I first entered these Doors of Terror, you started coasting. Now you're really okay with Amy fighting alone in there? Wouldn't you be heartbroken if something happened to her?"

William smiled, "Aren't you here now? With you around, nothing can go wrong. Go for it, I'm rooting for you."

"FUCK! I came here thinking I'd toughen you up a bit, but it feels like you're toughening me up instead," Walker said, frustrated, giving William a deep look. "Are you really not coming in with me?"

William shook his head, "I still prefer being kept by a woman. There are plenty of treasures upstairs. Whether you can get them depends on yours and Amy's strength."
