"The engineering team captured a small comet ten light-years away, but the size of this comet is still large compared to Planet 4 in the Mingsheng Galaxy, so it took the engineering team five years to flatten it," said Mr. Cai. （）

It took ten years to change the comet's orbit, and then it took two hundred years for the redirected comet to reach Planet Four.

The impact was done 10,000 years ago, and then the transplantation of biological species, which was much more detailed, and we couldn't allow organisms outside of our control to reach new planets.

Then there is the transformation of the climate, in this regard, we rely more on the adjustment of the natural environment, and we play a role in guiding the situation at most.

In general, it is impossible to complete this project without hundreds of thousands of years, and this is still a relatively fast speed, unless you find a planet that is originally extremely perfect. ”

The students in the audience sounded a little strange: didn't it take a few hundred years to cut a comet, hit a planet, and change the environment? How could it take hundreds of thousands of years?

Teacher Cai seemed to understand everyone's thoughts, so she went on to explain: "The reason why we say that 100,000 years is fast is because we have not counted the time to find a habitable planet.

It is also extremely difficult to find a suitable comet near the planet. If there were no comets near the habitable planet at all, we would have to abandon the planet as well. ”

Speaking of which, Teacher Cai Lin played another picture, which was exactly what the engineering team had done in the Mingsheng Galaxy before.

Three huge ships are docked around a comet, and crystal cannons are bombing the comet.

But the ship's crystal cannon is not the main weapon to weaken the comet, after all, the comet is so huge that it is like a moving planet.

The purpose of the crystal cannon is actually to make holes, and its purpose is to drill the installation point of the bomb on top of the comet.

Three giant pillars of light were connected to the comet from three different positions, and majestic energy surged out, and the comet was covered with fog, which was the water vapor evaporated by the energy.

The three cultivators avoided the pillar of light and flew towards the comet, and the camera switched to one of the cultivators.

After he broke through the mist, a frozen world appeared in front of everyone.

Icicles are as sharp as blades, and the thick mountains point straight into the sky, and their tips are glowing with blinding cold light. The comet appears rugged on its body.

The side of the comet facing the star was directly hit by the light, as if bombarded by a laser, and a large amount of ice collapsed and flew up, most of which transpired into water vapor, and flew to the back of the star, and then was absorbed back by the comet.

A small amount of water vapor flew away from the comet because of its speed, pulling back a tail hundreds of millions of kilometers long, which is the beautiful comet tail left by the comet in space.

The cultivator's situation was very dangerous, and from time to time cracked ice would whizz by, as if he were walking through a meteorite rain.

The ice cubes were as small as houses, as big as mountains, and the black pressure passed over his head, and even if they looked at the images of those years, the students present still gasped in unison.

It's dangerous!

This cultivator's strength must be above the Spirit Rank, and he should be close to the top of the Spirit Rank. I saw him like a swimming fish, always turning danger into a disaster at the most dangerous moment.

The two icebergs roared in, and in mid-air, they squeezed each other, so that more debris burst out, and the environment in the air became more complicated.

The cultivator didn't shake or mess up, and saw that his body twisted and went directly into the gap where the two icebergs met.

The cultivator was like getting into a piston, the icebergs were attracted by gravity, and they squeezed each other again, and the gap that was originally ten meters away instantly narrowed, and the mountain closed together as if it were pouring down.

Amid the exclamations of the students in the audience, the cultivator made a move.

His whole body glowed, and a dazzling ball of colored light wrapped around his body. This ball of light has a temperature like the sun, and as soon as the ice mountain gets closer, it immediately begins to melt, and the water flows down the iceberg like a waterfall.

The cultivator was like a bamboo, and he passed through the two icebergs, leaving a long passage behind him, and he got out of the predicament in a blink of an eye.

After descending dozens of kilometers, there is relatively less broken ice, but more water vapor rises.

A few kilometers away from the cultivator, a huge pillar of light stood up to the sky, and it was the crystal cannon ray that the spaceship blasted down.

The cultivator did not hesitate and immediately approached the ray.

It was obviously a skillfully coordinated team, and when the cultivators approached more than a thousand meters away from the pillar of light, the pillar of light disappeared and the ship stopped bombarding.

The hole that had been blasted out by the crystal cannon began to close immediately, and the temperature on the comet was too low. The cold, it seems to freeze everything here.

Without any hesitation, the cultivator immediately picked up his speed, and his body crashed into the ice cave like a meteorite.

The "crackling" sound continued, and the ice that had just been frozen was immediately shattered by the cultivator, who quickly penetrated into the middle and lower parts of the cave.

Seeing that the cultivator shook it vigorously, a huge crystal ball the size of a grinding disc was thrown out of his bracelet.

The crystal ball is transparent, and the colorful energy inside is constantly surging, and a line of numbers is constantly flashing in the sphere.

Without any hesitation, the cultivator turned around and flew towards the entrance of the cave, smashing the ice behind him that had frozen again, and then stabbing into the sky like a sharp arrow.

The other two positions were the same, and all three cultivators had completed the installation of the crystal ball, and they urgently flew back to their respective ships.

After recovering the three cultivators, the spaceship began to retreat urgently, and the huge hull was as agile as a swimming fish, and it turned around and fled into the vast space.

With a "boom", the image began to shake violently, and three walls of light pierced the sky like sharp blades, and the violent shock wave chased after the spaceship, and the light dissipated, and the huge comet was easily cut into six pieces by three bombs.

Two years later, the image is still the same three ships, but the repairers are no longer planting bombs on the debris.

At this time, six ice bodies flew side by side, and the comet was twice as large as it was in size. The cultivators chose the smallest of the six ice blocks, and they began to install propulsion units on them.

It's also a spirit weapon, but changing the comet's orbit obviously requires more powerful energy, so there are six propulsion devices in total, and they are much larger.

The device was activated at the same time, and six columns of energy erupted from the ice, and the smallest piece of ice began to change direction and drift out of the original comet's position.

The energy columns vary in size, apparently to control the direction of the ice's flight. As with all comets, a long comet tail was pulled out of the back of the ice, and a new comet was artificially created.

"This man-made comet accurately hit Planet Four in the Mingsheng System two hundred years later, and our planetary transformation program has been a decisive success."

The audience burst into warm applause.
