As far as the lifespan of celestial bodies is concerned, the time of human development on the planet is not worth mentioning at all, but celestial bodies are not eternal, they will come to an end, and the earth is in this stage. At the end of the earth's life, human beings have found a planet suitable for human habitation, and the large-scale space transportation vehicles developed by the government will migrate citizens to the new "earth", this large-scale cosmic transportation vehicle for large-scale immigration needs to consume an energy spar on the earth, and the amount is huge, at this time, the vast majority of earthlings have immigrated to the new "planet" and live in it, but it is difficult to find a large number of energy crystals after several transportations, The government also organized the development of a one-man ascension device, which only requires a few energy crystals, and the equipment is distributed to each citizen of the earth, and when there are enough crystals, it can be ascensed.

At this stage, the plants of the earth are tall and full of vitality, the air is fresh and lively, and many people have cultivated true qi after practicing martial arts, if it were not for the harsh climate and environment on the earth, coupled with the sound and yin of the coalition government, no one would believe that this would be in the last days. However, natural disasters such as huge tsunamis, erupting volcanoes, and strong earthquakes are frequent, the earth's ozone has been greatly reduced, and the dissolution of glaciers has caused the ocean to occupy 80% of the earth. The drastic changes in the environment and climate have made the people left on the earth panic, and with the coalition government building a steel alloy city, using technology and martial arts to carry the fierce beasts, people have slowly settled down from the initial panic, actively organizing to resist the disaster, and at the same time looking for energy crystals to soar.

Fierce beasts are tall and ferocious, very spiritual, and even more powerful in reproduction, on the other hand, human beings have been tired of dealing with natural disasters for a long time, and their reproduction has decreased, if it were not for the prevalence of self-preservation and force by relying on technology, the earth may have become a world of mutant beasts at this time.

There are ten major cities on Earth, with a population of less than a billion people, and each city is covered by forests or seawater, so you need to face a variety of fierce beasts to get from one city to another. Jiangcheng is one of the only ten remaining cities in the two continents, with a population of only 20 million, this is a complete steel alloy city, the periphery of the city is covered by dense greenery on three sides, on the one hand, it resists the invasion of the sea on the mainland, but also lives a lot of fierce beasts, and the remaining side faces the ocean, the city is surrounded by huge and tall walls, and the walls are covered with ultra-lethal weapons and armed forces, and it is necessary to pay attention to the attack of the beast tide at all times.

Jiang Yuan is a native of Jiangcheng, has lived in Jiangcheng for more than 40 years, is an ancient martial arts fanatic, and was sent by his father to learn boxing from a friend in the army since he was a child. He also has talent in his own right, and when he was an adult at the age of eighteen, he was already a master of dark energy, and after leaving the school, Jiang Yuan relied on his ability to go to the adventures and martial arts of heaven and earth elixirs around the world, seeking a deeper realm of martial arts. It was in an adventure that Jiang Yuan would be in danger of life and death for nearly two years, and in this more than a year, the federal government transferred most of the people to the new planet, including Jiang Yuan's family, and then the earth collapsed, the sea water poured in, volcanic eruptions, birds and beasts roared, the continent was constantly flooded by the sea, the living space of human beings shrunk, and the birds and beasts mutated so that the remaining people established steel alloy cities and scientific and technological armed protection. At the moment, there were five people sitting in Jiang Yuan's house.

"Lao Jiang, we haven't seen you recently, hasn't the fierce beast tide recovered from the injury some time ago? If you don't contact us again, we'll think you're already, hehe. Liu Kou, a drinking friend and neighbor of Jiangyuan, laughed teasingly, the long scar on his face was wriggling from laughter, unusually hideous, he served on the front line of the army, and the scar on his face was left by the fierce beast.

"The body has already recovered, and the exercises are still a little refined. Recently I was at home exploring the path of practice and other ways of ascension. Jiang Yuan smiled, and then sighed: "Recently, those fierce beasts have become more and more rampant, and they have begun to gather in the surrounding area, and there have been three fierce beast tides in the past six months, and this is almost the fourth time." ”

"Damn! You martial arts madman, you have already practiced Tai Chi to the peak of chemical strength, most of the hot weapons are helpless to you, I really envy your opportunity, like I have just entered the chemical energy, even if the dragon and tiger thunder sound refining body, this life will not be able to catch up with you. Liu Kou sighed, he was a little jealous when he thought of Jiang Yuan's opportunity in that devastating disaster.

"What about the peak of Huajin, I still can't get out of this cage, not to mention that I am separated from my parents and lose the opportunity to live on a new planet. The environment is even harsher now. Jiang Yuan held his mouth and said, in the adventure when he was young, Jiang Yuan, who had the internal strength of Taijiquan, broke through the energy in one fell swoop, and washed his body in the energy tide, and he had cultivated to the peak of the energy for so many years, and his mental power was more keen, and he was even more observant within 100 meters around.

"You have it, even the general of the city of Deyuan admits that it is far from powerful, and calls you a land fairy-like figure, think about it, we are still stumbling inside, and we don't know when we will be drowned in the tide of fierce beasts. Now we have fewer and fewer opportunities to leave, and although the population of a city like Hanshi has lost 30% of its population due to a volcanic eruption, it is said that many people have picked up a lot of spars, and now most of them have soared away. The fat man sitting next to Jiang Yuan was full of envy and said, the fat man's name is Xia Kao, he works at the grassroots level of the government, his personality is a little weak, but he is very righteous, Jiang Yuan recently studied several ancient books such as meridian diagrams, which were obtained by the fat man and his lover.

"Since the two devastating explosions in the past, volcanoes, earthquakes, tsunamis and other disasters have become more and more frequent, and the federal government has organized activities to resist animal tides and defend against natural disasters, which has cost a lot of people. But I've heard that someone has dug up a hedron in the body of a fierce beast in the deep sea, so why don't we try our luck? Jiang Yuan said to the tall and thin man opposite, the tall and thin man is called Guo Jin, a captain in Xinjiang City, with good piloting skills, he and Xia Kao are Jiang Yuan's childhood friends, in this era of fierce beasts, a good captain is welcomed by the government.

"There are very few spars in the recent tide of fierce beasts, isn't it too risky to go to the ocean to find them?" The fat man was a little afraid.

"Fatty, are you scared? Wealth and danger are begging," Guo Jin said with a smile.

"Guo Monkey, you don't talk about the wind and cold, you drive the rear, you have also seen the tide of wild beasts, and the fierce beasts in the sea are even more dangerous and abnormal, although there is a chance of bursting spars, the probability is not high, the most erupting spars should still be volcanoes, and the Tianchi volcano may erupt recently, because in Tiancheng, we can't be released." The fat man said with a roll of eyes at the tall and thin man.

"The passage between cities is too strict, not to mention that there are a lot of fierce beasts in the middle, and even if the news of the eruption of Tianchi Volcano is true, the volcano will not be as large as Sakurajima Volcano, and even if it erupts, it will produce very little spars," Liu Kou analyzed.
