It's reasonable for me to have a two-way foil for a second-level civilization, right?

Every step is designed just right.

But that doesn't mean it's without flaws.

On the contrary, this plan has one of the most fatal flaws.

It has only a framework and no detailed implementation.

After realizing this, Kong Xingbang frowned instantly.

"Academician Kong, what do you think of this plan?" Lv Yongchang noticed Kong Xingbang's expression and asked immediately.

Kong Xingbang fell into hesitation.

Speaking out this kind of thing directly will offend people!

But thinking that this plan involves a lot, he still gritted his teeth and said the problems he noticed.

Contrary to Kong Xingbang's expectation, not only did Lu Yongchang not show any displeasure, but he laughed loudly and said, "Hahaha, as expected of Academician Kong, his vision is really vicious!"

"Mechanical design is not my strong point. Random design will only increase the jokes, so I simply left it empty."

Kong Xingbang's eyes instantly became strange.

Judging by the meaning of this, Lu Yongchang couldn't have completed the plan alone, could he?

When he asked, Lu Yongchang nodded with a face of course: "Of course I did it by myself. Don't you think there is someone in the Institute of Aeronautics and Astronautics who can help me with this?"

Kong Xingbang: "..."

It's broken, let him install it.

Not to mention anything else, just relying on this detailed plan, Kong Xingbang believed that Lu Yongchang's attainments in mechanical engineering were enough to crush most of the professors present!

And this, in Lu Yongchang's mouth, is he not good at three words? !

"Academician Kong, I wonder if you have any research on moon mining?"

Just when Kong Xingbang was lamenting that the back waves of the Yangtze River pushed the front waves and the front waves died on the beach, Lu Yongchang's questioning voice interrupted his thoughts.

Kong Xingbang pondered for a moment, then said slowly: "Moon mining...the first thing to solve is the problem of materials."

"In the ultra-vacuum and extremely low temperature environment on the lunar surface, the sealing ring and lubricating oil are easily deteriorated."

"Additionally, there are corresponding problems with the device in terms of fatigue, ductility, and surface friction."

"The bombardment of tiny meteoroids, the influence of moon dust...these are all factors that must be taken into consideration."

"Also, since the moon's gravity is only one-sixth that of Earth's, the stability of mining equipment is also a big concern."

Lv Yongchang looked at Kong Xingbang who was talking eloquently in front of him, his eyes gradually brightened.

"Academician Kong, how about you take charge of this project?"

Kong Xingbang: "?!!"

……

After some "pleasant" discussions, Kong Xingbang took over the stall with a face full of "joy".

"Okay, the meeting of the Moon Palace Project is over."

Lu Yongchang, who left behind a burden, nodded in satisfaction, and looked towards a corner of the auditorium: "The next thing is the second project, the Biosphere [-] project."

Several unremarkable professors of biology looked at each other, and a gleam burst out of their eyes!

After the professors of mining and mechanical engineering in the auditorium left, several biology professors quickly ran to Lu Yongchang.

"Professor Lu, are you sure you want to start the Biosphere [-] project?"

"The Biosphere [-] project you are talking about is the project of the United States?"

Faced with one question after another, Lv Yongchang quickly pulled out a few proposals from the pile of documents in front of him, and put them in front of several biology professors.

……

While several professors were studying the proposal, Lu Yongchang sat on a chair and closed his eyes slightly.

With the movement of his thoughts, a flash of fluorescence slowly emerged in the depths of his mind, quickly dragging his consciousness into that fluorescent green world.

On the originally dim technology tree, several white light spots have already lit up.

[Nuclear Energy Control: Fusion Reactor Miniaturization Technology]

【Electric Propulsion System: Preliminary Mastery of Hall Thruster】

The originally dim cursors of these items have already lit up with white fluorescent light at this moment.

Lu Yongchang's eyeballs moved slightly, and he looked to the side.

Next to the Hall thruster technology, a dim white line suddenly appeared, and the white line connected the cursors that dimmed one by one.

[Nuclear Energy Control: Helium Trifusion]

【Biosphere: Artificial Ecosphere Technology】

【Hibernation Technology】

【Space Elevator Technology】

【Spaceport Technology】

【…】

Until the end of the line of sight, an extremely dim cursor appeared in front of Lu Yongchang: [Starship Manufacturing]

Lv Yongchang thought again and exited the system in his mind.

He sighed slightly.

According to the division of technology on the technology tree, human beings are still very far away from making starships!

According to his groping during this period of time, he also thoroughly understood the function of this system in his mind.

The first and most important point is to guide it to the most correct scientific research direction.

Second, he can judge his mastery of this technology by observing the brightness of the cursor.

Other than that, everything depends on its own efforts.

Chapter 83 Don't worry, the funds are enough

According to the brightness of the cursor in the system, he can clearly see the degree of his current mastery of these front-end technologies.

If the brightness of the cursor is divided into a level, it means that the brightness of the cursor of helium trifusion has reached 90% of the normal brightness!

This is also in line with Lu Yongchang's situation at this time.

The reason why helium trifusion has not come online for a long time is that the biggest obstacle is the problem of raw materials.

As long as the helium three raw materials are solved, helium three fusion can enter the application stage at any time.

Leaving aside helium triple fusion technology, the second brightest technology is biosphere technology.

Almost 50% brightness.

This is also normal.

After all, the Biosphere [-] project was not Lu Yongchang's first idea.

It was originally a miniature artificial ecological cycle system established in the United States.

As for Biosphere [-], it is naturally the earth on which human beings depend.

The original intention of the project was to demonstrate the feasibility of closed ecosystems supporting and sustaining human life in outer space.

Simply put, it is whether human beings can recreate a stable closed ecosystem outside the earth.

This technology has great significance for interstellar exploration.

Whether it is a starship for interstellar navigation or alien colonization, artificial ecosystem technology is an essential front-end technology.

The Biosphere 1.3 project in the United States covers an area of ​​[-] square meters and is about eight stories high. The main body of the building is a glass building with a sealed steel frame structure.

In order to completely simulate the earth's environment, Biosphere [-] simulated most of the environments on the earth, including deserts, swamps, thorn bushes, rainforests, savannahs, and even oceans.

In addition, in order to more realistically simulate the ecological environment of the earth, a total of about 4000 species have been introduced into the circle, including about 3000 species of animals and plants, and about 1000 species of microorganisms.

In order to ensure that Biosphere [-] is completely isolated from the outside world, the United States even poured two meters thick concrete under the entire building decades ago!

In addition, Biosphere [-] in the United States also strictly sealed all the doors and windows.

These measures make the airtightness of Biosphere [-] very high, which is basically equivalent to the second world.

After the completion of the project, the United States sent several scientists into it for several years of scientific research.

According to the original design of American scientists, after Biosphere [-] starts to operate, it will become a separate entity. Except for the energy source from the sun, everything else will achieve perfect self-circulation.

Oxygen and carbon dioxide will form a perfect cycle under the photosynthesis of plants, and food for scientists will be produced by crops inside Bio[-]...

Everything sounds so beautiful, like a paradise.

But unfortunately, all of this was the fantasy of American scientists.

After Bio[-] started up, the first problem that arose was the internal oxygen concentration.

The large number of microorganisms living in the soil caused the oxygen content to drop at a rate of 0.5% per month.

As for the carbon dioxide produced after a large amount of oxygen is consumed, most of it is absorbed by the concrete underground.

This directly led to the collapse of the entire circulation system.

Even, the change of oxygen concentration also led to uncontrollable changes in the ecosystem.

Pollinating insects are extinct, ants and cockroaches are rampant, and tropical rainforest plants are growing rapidly...

Even the few scientific researchers who entered it quickly became extremely thin!

The final result is naturally to pump pure oxygen into it by outside staff.

The moment pure oxygen was pumped into Bio[-], the entire plan failed.

In the end, the first man-made ecological circle project of mankind has become a tourist attraction, and anyone can enter it with only a ticket.

Thinking of this, Lu Yongchang couldn't help but sighed deeply, and a somewhat complicated look appeared in his eyes.

As a scientist, he deeply regrets this situation.

……

"Professor Lu? Professor Lu?"

A soft call from the side interrupted Lu Yongchang's thoughts.

Lu Yongchang opened his eyes and looked in the direction of the voice.

I saw several biology professors looking at him expectantly: "Professor Lu, we have finished reading the proposal."

Lv Yongchang chuckled: "Several professors should be focusing on the direction of man-made ecological circles. How about it? Is there anything you want to add to this plan?"

The leading professor looked slightly serious, and after pondering for a moment, he whispered: "If I'm not wrong, Professor Lu, you should have borrowed the data from the United States, right?"

Hearing this, Lu Yongchang couldn't help being happy.

He waved his hand casually and said, "Hey, why do you say it sounds so good, why don't you learn from it..."

"I just changed a few obvious problems. If you just say copy, I will admit it."

"What? Is there a big problem with the project?"

The ready-made template is placed here, is it possible that he still wants to be a saint and spend a lot of money to study one by himself?

This impure brain was kicked by a donkey!

Big deal... When the time comes, after you succeed, give Mi Guo a verbal thank you.

The eyes of the leading professor were full of astonishment.

He didn't expect Lu Yongchang to admit this so freely.

He shook his head with a wry smile and said, "There is no big problem with the project. After all, the country's scientific research capabilities are there."

"It's just some small details that need to be improved."

"The selection of biological species still needs some work."

Lu Yongchang nodded lightly: "Can you complete this project?"

The leading professor suddenly suffocated and looked at Lu Yongchang in disbelief: "Lu, Professor Lu?"
