"Is it possible that the divine weapons of those fighters were found in this kind of synthetic metal?"

Xiao Hei and he exchanged a smile.

The remnant soul inside the jade pendant was dumbfounded.

"Wow, ten-thousand-year-old meteorite iron! There's so much of it! With the techniques I teach you, you can even fight against five, no, ten ninth-tier Dou Zong!"

"Am I crazy? I'd go fight them." Fang Zhiyi cursed, then looked at the jade pendant. "But we can discuss your ideas, such as how you came up with the principle of absorbing battle qi from others and turning it into your own."

Peng Huan'er felt inexplicably uneasy. Not only had the young master not returned recently, but his companions had also stopped showing up. Only Wu Dadan would often bring messages, looking exhausted, asking for either food or tools.

"The shovel I just picked up a few days ago is already broken? What are you doing?"

Although Wu Dadan looked exhausted, his eyes were filled with barely suppressed excitement: "Hehehe, big secret, keep it a secret!"

These actions went largely unnoticed; everyone knew that logging in the deep mountains and transporting grain and tools were perfectly normal.

In the valley, a dozen people worked together to pry open a twisted door, with dozens of damaged tools lying nearby.

The moment the door opened, Li San and the others were stunned. Behind the strange door was a mysterious space, and they had never even heard of the things inside, let alone seen them.

Fang Zhiyi, on the other hand, finally breathed a sigh of relief.

Seeing Fang Zhiyi walk in without any precautions, Wu Dadan tried to stop her, but Fang Zhiyi waved her hand, as if she was very familiar with the place.

"Young Master, where exactly is this place...?"

"future."

Seeing Fang Zhiyi fiddling with those things that looked like torture instruments, Yu Pei panicked.

"Great hero, elder brother, ancestor! Please don't mess with me! I'll tell you everything I know! My mother remarried when I was three, my father remarried when I was four, and when I was five..."

"Can you shut up?" Fang Zhiyi interrupted impatiently. "You don't understand science."

Looking at the dilapidated laboratory before him, he was filled with mixed emotions. He never imagined that he had only started, but that his successors would have achieved so much.

Even he needs to spend time studying it.

Xiao Hei, on the other hand, was used as a detector and reluctantly helped him search for other usable things.

"Humans are truly terrifying..." Fang Zhiyi sighed as she flipped through the notebook filled with notes. "It's hard to imagine that someone who has reached such heights could still destroy themselves."

His finger hovered over the last page of the notebook.

The composition and concept above are clearly something you only see in science fiction movies.

"A starship..." Fang Zhiyi stared intently, not even noticing that Xiao Hei had returned to her side.

"What, you're going to build a starship?"

Without turning his head, he said, "Nonsense. At this level, even building a car is difficult, let alone a starship. Technological progress requires massive resource support... and I don't understand it either." He closed the notebook. "But I think I understand why the world has become like this."

"Hmm? You guessed it again?"

“It’s not a guess, it’s a speculation.” Fang Zhiyi looked around. “The development of technology is constantly consuming energy. This war destroyed the vast majority of things, which led to the current scarcity of resources. A single battle qi is enough to keep humanity fighting over it.”
