Species on any planet should have an obligation to protect their planet. At the stage of level 5 civilization, civilization has reached the point of destruction of the planet.

When the humans of the Tower Star unscrupulously released poison gas and nuclear weapons to kill species, a plan to kill all species in Tie Tower Star has begun.

On the star gate occupied by the sea urchin tribe, colorful balloons can often be seen flying towards the sky. This release lasted for more than two hundred days. A small cardboard box was hung under each balloon. When the balloon flew to a certain height, the cardboard box would fall down and fall on the ground. These small gifts were often some nerve gas.

Falling into the city may cause 100 to 200 square meters of poison damage. Sometimes it is a blasting incendiary bomb. For the tricks like the Sea Urchin Clan, the two major warring forces of the Iron Tower Star respond to this harassment with a smile.

For this kind of balloon bomb, the accuracy is very low. Nowadays, large areas of coastal areas on the planet are covered by nuclear, biochemical pollution areas. These balloon bombs do not fall into the city, and there is no harm in landing in other places. Now the commanders of every city are defending the opponent's ballistic missiles and aircraft groups. They don't care about this drizzle-like small bomb, just use anti-aircraft artillery to smash it.

However, everyone was wrong. The sea urchin tribe's revenge on this planet was serious, and the small bombs hanging on the balloon were actually not for bombing people, but for covering up other things.

Because of these dangerous small bombs, all forces' handling plans are to shoot them down, rather than relying on looking at the structure of the balloon bomb.

Everyone thought that this balloon bomb had nothing special, nothing more than a hydrogen balloon to carry this small bomb. Of course, no one leaned over to see the bomb. It was too dangerous, after all, it was an explosive. In a small dangerous obstacle and when everyone felt that it was unnecessary to see it, the Iron Tower Stars people indulged this floating object to fly in the sky for a year.

And there was no sign of stopping it. After a year passed, Ren Di realized the situation on this planet. When Ren Di flew into the sky and observed it for a while, he sighed. The Iron Tower Star will become a Jedi within five thousand years.

The purpose of the sea urchin group to release balloons is not to kill them for bombs, but to have problems with these balloons themselves. There is hydrogen inside the balloon, as well as fluorochloromethane and fluorochloroethane. Of course, these substances mixed with hydrogen balloons also have the familiar name Freon.

This substance is chemically stable and can act as a catalyst in the process of converting ozone into oxygen. On Earth, when humans prohibited the production of this chemical, they have already emitted 20 million tons of the atmosphere. However, it should be noted that humans' emissions are unintentional. Since Freon is heavier than air, most of them stay in the troposphere and can reach the stratosphere where ozone accumulates is only a very small part.

And it is such a small part that has caused the ozone layer in the north and south and the ozone layer holes on the Qinghai-Tibet Plateau. Now this balloon is deliberately released to the ozone layer. The hydrogen balloon directly brings Freon to the stratosphere. In a year, at least one million tons of Freon was released.

Destroying such a powerful destruction of the ozone layer is not about pressing a button to emit a light to destroy the blue sky, but about this kind of ordinary balloon. Whether it is a balloon, hydrogen, or Freon, it is not difficult for industrial countries to produce.

More importantly, no one in the Iron Tower can realize that this situation occurs, the seemingly simple structure, and a dangerous blast, which makes people have no interest in seeing it, and are unwilling to do this dangerous action without any trouble.

The ultraviolet rays in the sky are getting stronger and stronger. Under the gray sky, there is a yellow color. The higher plants will be completely destroyed, and only a few plants will survive.

Ren Di walked under a big tree, and the tree had no shade. After all the leaves fell out, branches like skeletons stretched weakly above. Angiosperms are higher than gymnosperms, with larger leaves and easier to absorb light. However, now is the doomsday of angiosperms. The wide leaves died after being exposed to strong ultraviolet rays for more than a dozen hours.

Ren Di sat on the numerical value and looked at the gray and dazzling sky, and asked Sun Bo, the follower beside him, "Sun Bo, when will the Iron Tower Republic wake up?"

Ren Di commented that this person who was framed in the laboratory was that he was not suitable to survive there. Sun Bo was one of the people who fled under the nuclear bomb. Under the rule of the Tianlang Society, he was obviously not a hard-hearted person. Of course, he was also the one with a higher probability of death in this era.

Sun Bo looked at Ren Di and said, "Boss, I don't know when the war will end. And why did you leave Tianlang?"

Ren Di said: "Because people like you can't survive, I don't want to stay. People like you can't survive, and I can't survive in the past."

Sun Bo said, "Since you hate there, why are you still?" Ren Di said, "I am not suitable for this era, nor do I need to be suitable for this era. I have completed the process of going in the era where I grew up. Being able to become like this means that I am right at that starting point. But in this era, this starting point, I dare not say that your starting point is wrong."

Ren Di patted Sun Bo on the shoulder and said, "So, you have your path. This era is not suitable for you. For yourself and for the evolution of this era, you should be braver and show the courage to change."

Sun Bo's fingers were embedded in his palm and asked confusedly: "Can I change?" Ren Di shook his head and said: "Maybe you will die tomorrow, or you may encounter opportunities tomorrow, but" Ren Di smiled happily and said: "Be ready at all times, as long as you can persist in preparing for the future, during the period of your life, you will be a strong man."

Sun Bo nodded. Seeing this, Ren Di was a little cheerful and said, "Then it's settled. You have to keep your promise now. I can no longer change it, and I can't do anything to change it."

The conversation ended, and the two continued to walk on the desolate land, and there was still 1,300 kilometers away from the safest entrance to the underground world. Walking with their feet, Ren Di would lead the way for Sun Bo, and of course he would accompany him to complete the journey. The two walked along the rolling ground with yellow sand. This was a test of patience for Sun Bo, and he needed to wait for the coming new world in the unknown.

For Ren Di, he was also waiting, but the person waiting for this journey is the one next to Ren Di.

The camera switch has become a fierce battle field elsewhere on the Iron Tower planet.

On the surging sea, the strong waves rolled up by the strong winds covered the steel warship again and again. In the wind and rain, the steel warships raised their heads again and again with benefits.

In the 21st century, only warships can pass through such winds and waves, and in the 21st century, warships will not make any troubles in such weather. Navigation in this climate will greatly damage the keel structure of the ship.

And now it is a battle period, and a large fleet is leaping across this area in the waves of sea. Some smaller destroyers in the fleet are shaking, as if they are likely to overturn at any time.

There will be no such spectacular scene on the earth. In the wind and waves, steel clusters are moving forward collectively under the water flow of propellers. This time, the number of large fleets attacking with the cover of the storm is as high as 5,000.

The aircraft carrier has no combat effectiveness in this weather, and the craftsman of this combat plan is now on a battleship with a displacement of 60,000 tons. Among this battleship, a group of officers wearing fiery red naval uniforms are drinking tea. Although the small battleship is swaying in the wind and waves, the interior of this large battleship is still very stable.

The battle roadmap is shown on the huge screen. The battleship cluster on the sea will carry out a torrent-like strike against the coastline controlled by the SkyCracks under the cover of a storm.

From the meteorological map, this is a rare storm with three typhoons connected together. The surrounding walls are covered with city overhead views. On these cities, the locations of star gates, as well as population gathering places, airports, and material warehouses with different strategic significance are marked with red, green, yellow, purple and black, and four colors.

These points indicate that military values ​​and degrees of importance are different. The heavy artillery of the fleet cluster will be bombarded by these shore targets according to their priority. The code-name of this large-scale strategic attack is Hurricane.

In this large-scale military operation, the time traveler from the Magic Crystal played an important role in it. After the meeting in the battleship captain's room was completed.

An officer walked into his lounge, closed the door, spread his hands, and a light curtain appeared in front of him.

He said to the light curtain: "There are eight hours left." A female voice on the light curtain responded: "A large number of train cannons have been arranged on the shore. The Demon-killing Team and the Phoenix Team should have known about your military operation."

The man said, "What can we do if we know? The momentum they grasp has been set off by us and has been covered by us. What methods can they use to curb this attack?"

The female voice replied: "Okay, okay, there is no need to be proud. Your mission is planned very well this time. But the strong team is a strong team after all. We are not sure what methods they have in the end."

The man nodded and said, "You are right, I'm not proud yet."

The two continued to talk for a while and then hung up

The camera switches to the Tianxinghui side.
