When modern materials poured into the apocalypse like a tide, the descendants of the Xuanwu base finally broke free from hunger and cold and regained some of the dignity of human civilization.

However, they have not forgotten the selfless help from their ancestors. Instead, they deeply understand that survival in the end times depends not only on material resources, but also on the continuation of wisdom.

Thus, an unprecedented cross-time and space intelligence sharing plan was launched.

The scientists at the Xuanwu base, carrying the spark of wisdom for the end of the world, sat in front of the camera and began a great teaching operation.

"My dear ancestors, I am Lin Zhoumin, an S-class scientific research professor. Thank you for sending us food, which saved the lives of 5 million of us. Now, it is time for us to repay you."

An old man with white hair and beard stood in front of the camera, his eyes were bright and full of wisdom and kindness.

Behind him was a metal wall engraved with the Xuanwu Base logo, emitting a solemn and shocking glow.

His words were calm yet powerful, as if they penetrated time and space and directly hit the heart of every modern person.

"Today's topic is - controlled nuclear fusion. We will take you into the next technological era ahead of time."

The camera moves, and another teacher slowly walks towards the camera. He has short hair, wears a minimalist futuristic uniform, and holds a smart light pen in his hand, and starts demonstrating directly on the holographic screen.

"I'm Zhao Shuang, an S-class architectural engineer. Today I'm going to show you how to use the future 3D printing technology to build a hundred-meter-long post-disaster defense structure. The end of the world has taught us one thing: buildings are not only homes to shelter from the wind, but also fortresses to protect lives."

Next, the camera cuts to another smiling scientist, Li Kan, an S-level plant grower.

She held a plant for future improvement, and her voice was gentle and patient:

"Ancestors from the Golden Age, I know you are still worried about desertification and climate change, but don't worry, we in the future have found a solution - air planting. Let us teach you how to take root and sprout in the air."

Chen Huayuan, an S-level nuclear physics professor, stood in front of a huge reactor model, like an academic leader in the apocalyptic era.

He pointed to the future energy core, his tone firm and proud:

"Everyone, energy issues are the root of the ancient dilemma, but we in the future have solved it. Controlled nuclear fusion is not a dream, but a future that is within your reach."

The modern live broadcast room was instantly ignited, and countless scientists, engineers, students, and even ordinary people flocked in.

Everyone felt the shock of transcending time and space. Those doomsday scientists standing in front of the camera seemed to have walked out of the ruins of the future, bringing their sparks of wisdom to light the way forward for the modern world.

"What are the basic principles of nuclear fusion? Can you explain it in simpler terms?"

A modern college student asked cautiously.

Lin Zhoumin's kind smile emerged:

"Of course, good student. The key to nuclear fusion is high temperature and high pressure, which can combine light elements into heavy elements, thereby releasing huge amounts of energy. In other words, it is like moving the core of the sun to the earth."

The students were mesmerized by the lecture and took notes frantically, while they couldn't help but sigh:

"Nuclear fusion is so cool!"

On the other side, Zhao Shuang is demonstrating future construction technology.

Use a future 3D printer to print out a transparent piece of lightweight steel, and then directly demonstrate how it can be assembled into a defensive structure.

"Professor Zhao, why is it that this material looks like glass but can withstand the impact of alien beasts?"

A modern engineer couldn't help asking.

Zhao Shuang patiently replied, "It's very simple. This material is made from future quantum structural technology. It can absorb shock at the molecular level." He paused and changed the subject, "But don't worry. We will teach you how to make this material."

The modern engineer's eyes widened immediately, and his hands were shaking with excitement:

"Oh my god, quantum structural technology! If we master it, modern buildings can increase their earthquake resistance dozens of times!"

What brought the entire live broadcast room to a climax was the demonstration by the team of mechanics.

In the picture, several post-apocalyptic scientists stand in front of a pile of dilapidated scrap iron, holding welding guns and tools in their hands.

They cooperated with each other to disassemble, splice and assemble. After just two hours, a small mecha shining with metallic luster was born.

"This is a basic model of intelligent mecha."

The mechanic's tone was calm, but he couldn't hide his pride.

"Its computing core is made of discarded wafers. We will teach you how to create the most practical mechanical combat partner at the lowest cost."

Modern engineers were stunned, and the barrage of comments exploded:

[This pile of scrap metal can actually be turned into a mecha? Is this still the mechanics we know? ]

[The future mechanical technology is so advanced that mechas will become cabbages! ]

[Seeking tutorials, videos, and patents! ]

In the live broadcast room, modern scientists were holding small notebooks to take notes, and their wrists were almost cramped from writing.

"Future teacher, can I ask a question?"

A young mechanical engineer asked cautiously,

"How is the computing speed of this core chip optimized?"

"Good student, good question."

The mechanic nodded in satisfaction.

“We use multiple layers of parallel computing, and you can try to simulate this on a modern AI chipset.”

Modern engineers almost jumped up with excitement:

"Great! This will completely overturn our current mechanical design concepts!"

My dear, there is more to come after this chapter. Please click on the next page to continue reading. It will be even more exciting later!

At the same time, the botany course brought by Li Kan also became a highlight of the live broadcast room.

She demonstrated a futuristic technology called "air planting," which requires only a small amount of water and mineral elements in the air to make plants take root and sprout.

"This is an improved super rice variety."

He picked up a seed, his voice was gentle,

"It can grow in saline soils, deserts and even in soilless environments, and each plant can support five people."

Modern agronomists are stunned, and their eyes are filled with tears:

"The future has actually solved the problem of planting crops in the desert! This will completely change our food crisis!"

Ordinary spectators on the side couldn't help but sigh: "

People in the last days are so amazing! Why don’t we work hard? "

This live classroom across time and space not only made modern scientists take notes frantically, but also ignited hope for the future in countless ordinary people.

Netizens left excited comments on the bullet screen:

[People in the future are so kind-hearted. Their knowledge is our treasure! ]

[I hope we can work harder and not let our descendants live in such an apocalypse! ]

【Today I learned that the power of science can really save the world! 】

[I am so ashamed to be called ancestor by them! ]

[If you’re not careful, your generational score will be huge, and you feel like you have a lot of responsibility on your shoulders! 】

[Why should we lie down? ]

Modern scientific research institutions have been working day and night to tackle the problem. In just a few weeks, experimental equipment for controlled nuclear fusion began to be widely built, 3D-printed building prototypes came into being, and preliminary design plans for quantum machines were put on the agenda.

The sharing of wisdom across time and space has completely ignited modern society's enthusiasm for science and technology.

And all this... has just begun.
