The most famous mass extinction of life on the earth occurred at the end of the Cretaceous period, when a meteorite with a diameter of about 10 kilometers rushed into the atmosphere, and after colliding with the earth, it caused more than 148 kilometers of the planet to break the surface, and directly hit the earth's crust, causing the earth to have a terrifying crustal movement, setting off a death frenzy in the billowing smoke and dust, and the overwhelming tsunami and roaring volcanoes exterminated a large number of living things, and more deadly was the endless dust that was rolled up in the impact, forming a dust curtain that covered the sky and the sun.

The dust curtain cut off the sunlight, created a long ice age, the plants that could not photosynthesize died in large numbers, the herbivorous dinosaurs that lost their food sources also starved to death, the ecosphere has always been a link after a link, the mass death of the herbivorous dragons, and the carnivorous dinosaurs were also unable to support themselves, and then disappeared.

When the earth is restored to an environment suitable for the growth of life, and the overlords who have occupied the earth for more than 100 million years, the dinosaurs, have died out, and human beings have the opportunity to become the hegemon.

But now the sky is a giant colony ship with a diameter of ten kilometers? Even if its mass is not as good as that of the meteorite that exterminated the dinosaurs, the result is probably not much better, and under this level of impact, the surface ecosystem of the telescopic star will definitely be completely destroyed.

"We can't let it destroy the telescope like this!" Xu Mo said categorically, if Wangyuan Star ushers in the end of the world like this, won't Chengcai and Li Xiuning die?

Yin Xiuyun and Ahri looked at him in surprise, and then realized that he had taken out something like a flashlight from his space equipment.

"Shrink the light? Do you want to make your ship smaller? Yin Xiuyun immediately thought of Xu Mo's thoughts.

"That's right, the most important reason why this spaceship will cause a doomsday crisis is that it is too big and too heavy, which will cause a huge impact when it falls, which exceeds the carrying range of the planet's ecosystem, but the use of a shrinking lamp to make it small enough that it will no longer pose a threat to the planet in terms of volume and weight, won't this crisis be solved?" Xu Mo said optimistically.

Yin Xiuyun on the side clapped his hands and said in surprise: "Maybe it's feasible, but your little hand lamp is not enough." ”

Instead, she took out a huge device and placed it on the ground.

At first glance, the device looks like a cannon, but a closer look reveals that it is actually a more elaborate searchlight-like object supported by a bracket, with a "barrel" like a horn and a large mirror mounted on the "muzzle".

"Your small handlamp-type shrinking lamp is a civilian style, the use distance is short, the size of the object is limited, the power is even lower, and the effect of facing the huge colonial ship overhead is limited, and it should be a military shrinking gun like mine at this time."

Shrinking lamps and magnifying lamps are very practical magical props in the twenty-second century, with a wide range of applications, almost every family must-have, however, don't look at its high popularity and think that it is not worth mentioning gadgets, in fact, this highly popular props are the products of dimensional technology, and the scientific and technological content used can be said to be one of the top parts of science in the twenty-second century, this kind of magical props have been on the list of the world government's foreign ban, and it ranks high, Fortunately, the problem of the space-time hub led the world government to decide to cooperate with Xu Mo, and also released all kinds of controls on him, otherwise Xu Mo would not want to buy this kind of prop.

Of course, there are still restrictions, such as he can only buy the civilian version of the magnifying lamp or the zoom lamp, and the military minimization cannon, magnifying cannon, etc., must be used by members of the special incident response team such as Yinxiuyun.

After all, the science involved in this level of magical item is extremely complex, and if one is not careful, it can turn into a dangerous object that can destroy the world, and there are many restrictions on its use, which must be judged and used by professionals.

"As you know, the law of conservation is the basic rule of the world, as the so-called loss is more than enough to make up for the short, but where energy, mass, etc. change, there will inevitably be corresponding compensatory changes in other aspects, not to mention, the shrinkage and enlargement of life is more complicated, it is not that the cell becomes larger, the life body becomes larger, the cell becomes smaller, and the living body becomes smaller, which also involves a lot of essential mysteries of life."

Yin Xiuyun was debugging the equipment while talking to Xu Mo and the others, but judging from her tone, she was also nervous and wanted to relax herself in this way.

"The effect of scalable lamps and magnifying lamps is contrary to the limitations of this law of the world, whether their object becomes larger or smaller, even the mass changes together, and in the process, the corresponding mass and energy are not absorbed or precipitated, but their effect does not ultimately break the balance, do you know why?"

Xu Mo was happy to help Yinxiuyun relieve pressure at this time, besides, he was indeed very curious about the principle of shrinking the lamp and magnifying the lamp: "I don't know, can you tell us about it?" ”

Yin Xiuyun began to adjust the angle of the shrinking gun: "Actually, the magnifying lamp and the shrinking lamp can't change the conservation law, but they can't change it, but we can achieve the desired effect by replacing it." ”

She began to adjust some kind of coordinates on the control center of the shrinking cannon: "Generally speaking, after the magnifying light or shrinking light determines the application object, the magnifying light and reducing the light will 'cut' the application object and the space it is located in from reality, becoming a relatively independent part of this world, and then connecting the high-dimensional void space." ”

After adjusting the coordinates, Yinxiuyun began to click on the virtual keyboard of the device again: "After that, we can carry out energy and mass conversion between different dimensions according to our needs, such as shrinking the lamp, it seems that the person or object has become smaller and lighter, in fact, the person is still the person, and the object is still the object, but the value of the space around them has changed, and a large amount of mass and energy have been replaced with the high-dimensional void space, which is manifested in our vision, It's the shrinkage of their size and the reduction of their mass. ”

Xu Mo clapped his hands suddenly: "I understand, in fact, this is a bit like changing the concentration of the solution!" In the case of ensuring that the quality of the solution in the two containers remains unchanged, the value of the solvent and the solute can change in a kaleidoscopic way, the magnifying lamp is to reduce the solvent but increase the solute, and the shrinking lamp is to increase the solvent but reduce the solute, but as long as the 'solute' is not replaced by the life or object that represents the size of the organism or object that wants to change the size, it is not a big problem to replace the solute or solvent in other parts! ”

Yinxiuyun took the time to give Xu Mo a thumbs up: "That's right, the principle is like this, in this way, it still follows the law of conservation, but it can achieve the effect we need, so the magnifying lamp and the shrinking lamp are called 'conservation displacement device'!" ”

Xu Mo looked at the huge spaceship in the sky, and finally understood why Yin Xiuyun said that his shrinking lamp was not enough, the energy and mass replacement of this scale was definitely a heavenly scale, and it had to be completed quickly in a short time, whether it was the amount of calculation required or the energy, it was huge, not to mention, when it came to the survival of a planet and the life and death of countless lives, it was more reassuring to use a more professional instrument after all.

"Below, it's time to witness the miracle!" At this time, Yin Xiuyun finally adjusted the shrinking cannon and announced excitedly.
