"Gaia, invasive species are almost cleaned up, right?"

"You've cleaned up 40 percent of the invasive plants, and 32 percent of the invasive animals," Gaia said. Now, as long as you dispose of another 25,000 tons of garbage, you can be promoted to an intermediate Earth Emissary, and you can obtain [Life Permission] and [Earth Permission]. ”

At this time, although the invasive species in other provinces have not been eradicated, they have basically been cleaned up manually, and only a few are left.

If we want to eradicate invasive species across China, we will have to wait until next summer.

Moreover, before dealing with the invasive animals, Lin Han also needed to memorize a detailed version of the national map to facilitate the command of them.

Just remembering the maps of the southeastern provinces before, he was already a little overwhelmed by hurrying and hurrying.

The remaining 30 provincial-level administrative regions, a vast area of about 9 million square kilometers, make people feel a little scary when they think about it.

Of course, with so much map information on your back, the benefits are obvious.

At least, Lin Han walks in the southeastern provinces, no matter where he goes, he can directly choose the nearest and most convenient path, without asking others at all, he is even more familiar than the local natives.

Not to mention, combined with the perception of biological authority, he can almost focus on himself and influence and mobilize all living beings except humans within 30,000 square kilometers, which feels like a point of soldiers.

Knowledge is power, and that's true.

In a year's time, memorizing the national map is not a difficult task for Lin Han today.

As long as he is willing to spend more time, with his learning efficiency far beyond ordinary people, it is not impossible to memorize the world's geographic information.

Therefore, he specially commissioned the School of Geography of CUHK to order a giant three-dimensional globe, which not only contains a large number of regional divisions and traffic information, but also contains complete and detailed topographic information.

For the geography faculty of a prestigious university, there is no technical difficulty in making such a giant globe.

An experienced old professor, with a few students, can be completed quickly, quickly and well.

So when Lin Han returned to Yunzhou City, he received the three-dimensional globe he had ordered before—assembly parts in four large boxes.

"Giant stereo globe with a diameter of 4.6 meters, a total of 60 assembled modules......"

Lin Han looked at the information on the assembly manual, and was a little speechless for a while.

He casually said before, "It's okay to be bigger", but he didn't expect CUHK to directly achieve a diameter of nearly five meters.

With such a huge size, it is estimated that it is already the world's largest "magnetic levitation stereo globe". He can apply for a Guinness World Record whenever he wants.

With a diameter of 4.6 meters, this is far more than the height of the room in his house, and it cannot be put together even if it is assembled.

What's more, this globe has to be added with a magnetic levitation device.

Counting the magnetic levitation base, the entire three-dimensional globe must be at least 5 meters high, which is about to catch up with the height of a two-story building.

It seems that the top priority is to change to a big house as soon as possible.

The current Lin Han, who is a super-rich man in Yunzhou City, still lives in a small house bought by hundreds of thousands, which is indeed a bit out of place.

The reason why he never bought a luxury house before was mainly because he didn't particularly care about the living conditions, as long as it was suitable, he didn't pursue luxury.

Now that we have actual needs, we should naturally think about it.

Of course, before that, he still went to the Vientiane Laboratory first, and brought the four boxes of globe assembly parts with him.

The second and third laboratories have been preliminarily completed, and the site is located in the center of Qingnan Development Zone, and dozens of scientific researchers have been recruited and a number of advanced equipment have been acquired.

Most of these dozens of people are from prestigious universities, and most of them have master's and doctoral degrees, majoring in biology, agriculture and forestry, and computer science, followed by physics, chemistry, medicine, and machinery.

Some of these people are students recruited directly from universities, and the other part is the technical backbone of other enterprises and scientific research institutions.

Although they are young and their fame is not particularly loud, they are all carefully selected, and their abilities are absolutely fine.

After all, the treatment of Vientiane Laboratory can be described as unprecedented, and the competition is very fierce, and people who have no skills will not be able to enter at all.

A spark can start a prairie fire.

These dozens of people at the moment are the sparks of Vientiane Laboratory.

……

After coming to the laboratory, Lin Han first looked around, and by the way, he comforted a group of employees, and then found a doctor of physics surnamed Yang.

"Dr. Yang, I heard that you are an expert in the field of electromagnetism, I wonder how much you know about magnetic levitation?"

Dr. Yang wears a pair of narrow-rimmed glasses of the Italian brand, and looks quite delicate, but unfortunately he is a little early, in his thirties, and the top of his head is shiny.

He lifted his narrow-rimmed glasses: "Magnetic levitation, including low-temperature superconducting magnetic levitation, as well as normal temperature magnetic levitation." For low-temperature superconducting magnetic levitation, I don't have a special in-depth ......"

Lin Han waved his hand and said with a smile: "I don't need superconductors, I just want to add a magnetic levitation device to the globe." ”

Dr. Yang was stunned: "Magnetic levitation globe, this is very common, I remember that you can buy it on Alitao, and it doesn't seem to be expensive." ”

Lin Han explained: "It's not those flat globes on Alitao, it's three-dimensional globes, and it's a super large model, with a diameter of 4.6 meters. ”

"I've already brought the assembled parts of the globe, do you want to take a look?"

Dr. Yang nodded, "I'll take a look." ”

Then, he followed Lin Han and came downstairs to see four large boxes on the ground.

Inside the four large boxes, there are a large number of assembly parts, each of which has a different shape, and the potholes show the terrain, and at the same time, various geographic information is marked with color, including administrative divisions, transportation, etc.

Dr. Yang took a closer look, lifted another piece of the part, looked at the back, and then frowned and pondered.

"The stable magnetic levitation of irregular objects is indeed not easy to set. However, if Mr. Lin just wants to install magnetic levitation for this globe as soon as possible, there is actually a more convenient way. ”

Lin Han asked curiously, "What's the way?"

"The shape of the globe is relatively regular, as long as it is modified inside the hollow to stabilize the center of gravity and axis, and then set up the magnetic levitation, it is much more convenient than the ordinary magnetic levitation globe. ”

Lin Han asked again: "If you deal with it like this, how long will it take to do it?"

Dr. Yang thought for a moment: "A month at most will be fine." ”

"Then please, Doctor. ”

"Mr. Lin is polite, it's just a gesture.

Dr. Yang lifted his glasses and continued: "Moreover, the magnetic levitation setting of this globe suddenly made me think of a very interesting idea, which happened to be my first project when I joined Vientiane Laboratory......"

The two chatted for a while, Lin Han seemed to remember something, and suddenly asked, "Dr. Yang, I have been interested in physics recently, do you have any good books to recommend to me?"

"Good physics book ......," Dr. Yang's eyes lit up.

"How about the Ten Landaus?"

……

After handing over the maglev to Dr. Yang, Lin Han left the lab and made a phone call with a real estate owner.

“…… It's Mr. Lin, do you have anything to do with me looking for Lao Wang......"

On the other end of the phone, Boss Wang's slightly drunk and panting voice came, and at the same time, a faint soft female voice sounded.

Lin Han was a little embarrassed: "Ahem, Mr. Wang, you seem to be very busy over there......

"Not busy, not busy, if there is something to say directly. Boss Wang laughed, and the female voice in the background was much more obvious.

"It's not a big deal, I just want to buy a villa from Boss Wang, come and ask. Lin Han said.

"Oh?" Boss Wang seemed a little surprised, "Mr. Lin, you are such a pure-hearted person, why did you suddenly pay attention to the matter of the house?"

"It's nothing, it's just that I bought a globe more than five meters high, and I can't put it in a big house without changing it. ”

"Globe?" Boss Wang was a little strange.

Lin Han didn't explain much: "As long as there is a room that can be installed, or it is convenient to rebuild, the surrounding environment is better to be quieter, and there are no requirements in other aspects." ”

"It's good to say, I'll go and see it myself tomorrow, and I'll definitely satisfy you. ”

Boss Wang laughed and said: "Speaking of which, Mr. Lin, your life is really simple enough, hundreds of thousands of small houses, but they have not been changed until today." ”

……

With the help of the real estate boss in person, he found a villa that satisfied Lin Han the next day and paid the full amount happily.

Although the villa is indeed very luxurious, it is a third-tier city after all, and the price is more than 20 million.

The newly purchased villa has three floors with a two-storey study and a garden pool, and the surroundings are quiet and facing the mountains and water.

The interior decoration is perfect, and three large bookcases have been placed in the two-storey study room, which is quite grandiose, giving people a sense of the British Library.

What surprised Lin Han even more was that in addition to this study, the villa also came with a large basement.

Previously, in order to complete the commission of the Institute of Microbiology of Peking University, he deliberately bought two houses to open up and set up a monkey version of the gene mutation laboratory.

Although the cultivation of Wolbachia newer was successfully completed, the original laboratory was really as simple as it was.

He would inevitably do something similar in the future, such a large basement, and the sparse flow of people around the residence, it was simply too convenient to modify.

As long as the basement is equipped with a thick layer of lead plates on all six sides, you can do whatever you want inside, as long as you don't make an explosion, there is no need to worry about leakage of radiation or something.

Although the three laboratories in Vientiane are becoming famous, in fact, only the second and third laboratories exist, and the first laboratory is completely a pretense made up by Lin Han.

In this case, this basement can be used as the "first laboratory" in a sense, providing a special space for Lin Han to do some experiments that only he can complete.

Of course, the modification should be more serious, in addition to adding lead plates to prevent radiation, Lin Han also plans to install a layer of super alloy steel plates on the walls to ensure isolation and safety.

In addition to this, the entrance should be moved to the study, behind a bookcase.

A series of modifications in the basement were all done by Lin Han himself, although a lot of time was wasted due to unprofessionalism, but for the sake of insurance, he still didn't let others help after all.

It took him almost a month to complete the basement renovation.

The renovated basement was covered with a layer of superalloy steel on all six sides, as well as a layer of lead plates, and the original entrance was sealed, and a new entrance was opened behind a bookcase in the study.

Lin Han walked to the bookcase and slowly turned the huge bookcase, revealing the basement entrance at the back.

Between the walls, there was a heavy metal door, like the door of a bank vault, which was opened and closed by a mechanical combination lock.

Behind this metal door is the basement of this villa, which is, in a way, the real existence of Vientiane First Lab.

Lin Han patted the somewhat cold metal door and couldn't help but smile with satisfaction.

At this moment, his mobile phone suddenly rang.

"Mr. Lin, the magnetic levitation of the globe has been set, do you want to transport it to you?" but it was a call from Dr. Yang.

"You can just have someone transport it to my house. ”

"No problem. ”

In the evening of the same day, a truck carrying a half-assembled giant three-dimensional globe was transported to Lin Han's villa.

The back of the original dozens of assembled parts has been added with some plastic coatings, as well as some metal structures, which not only look potholed on the outside, but also become uneven on the inside.

But basically, as long as the outer convex part corresponds to the concave shape inside, the outer concave part is convex, and the inner part is convex, so that the center of gravity and axis of this three-dimensional globe are basically stable.

In addition to the original parts, there is also a magnetic levitation base, which looks like a plate, but it is more than two meters in diameter, which is quite huge.

After the initial splicing, dozens of parts have been put together into eight pieces, just in time to be brought in from the door.

After getting the study, Lin Han quickly put together the eight parts to form a complete three-dimensional globe, mountains, rivers, countries and regions...... are clearly and in detail marked on it.

Although the materials used to make the globe are either plastic, carbon fiber, or lighter metals such as aluminum alloy, after all, it is a giant globe with a diameter of four or five meters, and its weight should not be underestimated.

Rao used Lin Han's divine power to push this giant globe onto the magnetic levitation base, and it still took a lot of effort.

The floor shook faintly, and the globe was finally placed on top of the maglev base.

Lin Han wiped the sweat from his forehead: "Finally put it on." ”

The huge globe, sitting in the depression in the middle of the maglev base, is embedded in it, and it is tightly fitted.

"Now as long as the maglev device is activated, the globe should be able to float. ”

Thinking that such a huge globe was about to be suspended in mid-air, Lin Han couldn't help but feel a little curious and excited.

Plugged in the power, the indicator light of the magnetic levitation base flashed slightly for a while, and he immediately pressed the "levitation" button.

"Drip-"

The magnetic levitation base immediately lit up with a circle of blue light, flickering slightly, and the huge globe also trembled slightly, slowly rotating while slowly rising, gradually detaching from the base.

Just as Lin Han's eyes widened and he wanted to catch a glimpse of the world's largest "magnetic levitation stereo globe", suddenly the room flashed and fell into darkness.

There was darkness in front of him, and Lin Han couldn't help but be stunned.

Jump...... Tripped?
