Time Traveling System: Establishing The Last Stronghold for Humanity

Tham explored the house and found old electronic devices.

The house was abandoned; it seemed no one would live there again.

His knowledge of bioelectronics, which he had learned in the future, came to mind.

He remembered a special wristwatch that used body energy.

He couldn't create it in the ruined future.

But now he was back in the past, with more complete resources. It might be possible to create it.

"If I can create a body-powered watch like this now, it will be an unprecedented innovation," Tham thought excitedly.

"I must find a way to produce it."

But he knew well that creating such a complex watch wouldn't be easy.

He lacked the proper tools, production facilities, or even capital.

"Must start small," Tham decided. He pulled out the basic toolkit he brought back from his backpack.

Even though they were just old tools, for Tham, it was a good starting point.

He began by repairing and upgrading the existing old electronic devices, using the knowledge he gained from crafting in the future.

He tried disassembling various components and meticulously learned their mechanisms.

With effort and determination, his basic crafting skills slowly improved.

[Your "Basic Crafting" skill has improved.]

[Progress: 3%]

The system notifications continued to sound periodically, encouraging Tham.

He felt he was on the right track.

Days passed. Tham spent most of his time studying information from Luna's notebook and practicing his crafting skills. He noticed that Luna often complained about small problems in daily life.

"This is an opportunity," Tham thought. He began to see a way to generate income. He decided to start by crafting small items that could solve those problems, using his knowledge from the future.

He began by inventing a "long-distance messaging device."

With the toolkit he had and his knowledge, Tham spent several days designing and building his first prototype.

He faced many challenges, including finding suitable materials, assembling small parts, and testing performance. But with determination and patience, he successfully created it.

When he tested its performance, Tham was surprised by the results.

It worked excellently and was much more efficient than he had expected.

[You have invented the "Future Messaging Device."]

[Recommendation: This product has the potential to generate significant income.]

Tham knew this was just the beginning. He decided to offer it for sale to a small technology company.

He dressed as politely as possible and walked into the company with confidence.

The product presentation went smoothly. The company executives were very interested in Tham's device.

They had never seen such advanced technology before and saw immense profit potential from manufacturing and distributing this product.

"We are ready to invest in your technology," one of the executives said.

"How much do you want for the patent and production?"

Tham knew this was a golden opportunity to establish himself and raise capital for his grander goals.

He negotiated shrewdly, without revealing all the secrets of the technology.

He kept his knowledge of the body-powered watch as a trump card.

Finally, the deal was successful. Tham received a large sum of money from selling the patent and a share of the profits from manufacturing the future messaging device.

In addition, he also received an opportunity to join the company's research and development team, which would give him access to the tools and resources necessary to create other inventions in the future.

With the acquired funds, Tham began planning the construction of his stronghold.

He didn't just want a refuge, but a place that could accommodate many people and serve as a center for developing technology that would help humanity survive the disaster.

He used Luna's notebook as a guide for designing the stronghold, considering the needs and lifestyle of people in the past.
