" I will now explain the history of the world. Earth is but one of many planets within our universe, or as some would say- within the galaxy. Each planet was formed almost identically, minus a few distinctions. Each planet is called the same- Earth, but with different variations of the name. For example, Earth 1-100, Terra 100-200, Giai 200-300 and etc. these planets were created to be paradise with lush trees and flowing water. Natural Resources were provided for humans to live within this paradise. An invisible shield was placed on each of these planets, to hide them from outside dangers. So long as humans live in harmony with nature and each other, they would be shielded from outside forces regardless of what they did. All planets within the solar system of a hidden planet become empty, devoid of life, and appear solitary. In other words, there are alternative earths. Although There are alternative earths and galaxies, each individual is unique to their own planet.
If the people of a planet cause enough destruction, the shield will disappear before the planet is completely crippled and destroyed. Once a shield disappears, the planet will lose its protection, this includes from nature. Nature has a long memory, therefore every harm done by humans is remembered from the first day of creation. If mankind intentionally destroyed, pillaged, burnt and harmed nature for anything other than their survival, it will be remembered. This is also why animals and plants have now evolved and become aggressive towards. Only those predisposed to nature (plants, animals etc.) may make a contract with it. These will only be made when someone reaches a certain level. For everyone else, it is man against nature and vice versa.
The planet was shielded as there are many other beings, much stronger than humans. Other earths have magic, some far advanced in technology and others are based on cultivation. Depending on the degree of harm done, depends on how chaotic the planet is. Other than humans, there exists demons, monsters like trolls and goblins, dragons and sea creatures. Many of the beasts and monsters can be found in your own fairy tales and stories. Some people were imprinted with the knowledge to them so you can be familiar with them in case humans would cause the destruction of your shield. Many like elements will now dictate your life, created to aid you for your chance to survive. Of the many planets that are in existence, 20 have succumbed to complete destruction. Although no living human remain on the planet, the destruction caused monsters to arise from the putrid earth, poisoned by humanities baleful acts. These dead planets are the origination of many of the monsters you will be facing. They are paying penance for the destruction caused and a reminder of what would've happened had administrators not been issued on each planet. Data have shown that almost every planet have been or are being led to destruction by the acts of humans.
For these reasons humans are now required to fight for their own survival against monsters they have created. Gateways will be opened to different earths. Some gateway may lead to friendship and apprenticeships from older planets, some may lead to knowledge and others yet, will lead to death. The gateway will become a 2-way door, mostly dungeons for monsters to gather in order to continue their pathway of destruction. Other dungeons may lead to caves by many of the elders who have hidden away to practice their craft and rid themselves of human desires. Some are experimental rooms for mad scientists, searching for cures or creating equipment and weapons to fight against the monsters. Individuals may be spirit away upon entering a dungeon if it contains a cave with a master, they may have fate with.
Not all encounters will be positive. Some people who enter a hidden dungeon may be stuck, unable to escape their training for months, years or never". An encounter may put a person's life on the line, and they may even die. Just as well though, some encounters will be of great contribution and worth to a person. A person may find themselves in a gateway leading to a treatment center where years go by only to return to the moment they would have left. Not everyone will have this luck. Some people may learn knowledge of other worlds, languages or even more about animals. They may learn to become crafters, medics, tamers, magicians or cultivators and even gain countless levels in one setting. There are countless possibilities to evolve and many things to learn. Some people may even find themselves learning new skills, gaining an inheritance or maybe even finding love. These encounters, as mentioned, are extremely rare.
As one of the oldest planets to join the planetary warfare, you have all been given additional benefits. This is because of the Earth name; you are the oldest. It has taken millennials for you to cause enough damage to destroy your shield. There are many younger planets who have been at war for much longer than you. You all should be grateful you've done so well, as such All persons will gain one level as a gift, regardless of their status. The only monsters allowed for the next 2 months will be level 10 and below. A monster level is usually one level higher than human levels.
The number of gates will be limited to 5 per month. Starting at a beginning level and slowly increasing as needed. The more cleared, the higher the level and more that will appear. The forest and woods will be layered. Weaker monsters will be found in the outskirts and the stronger monsters towards the inner depths. If you are weaker than the gates, try to avoid going there. The gates will lead to death so if you are under level 5, or have not fought with monsters, avoid it unless you have stronger members in your party. Either level up in the outskirts of the woods/forest, or in the tower. Party member points will be significantly reduced for members not with the party. The gates will not appear until after the first 5 levels of the tower are cleared. When you are in the tower, you may continue to the next level after completing a level or you may leave the tower at any point. A gate, however, cannot be exited until it is cleared. Within the tower, every 3 levels will have a safe space for resting which will not be bothered by monsters and will remain neutral. You can earn points and rewards; whenever a level is cleared new equipment will be issued to the raiding parties according to their needs. Multiple people can raid the tower at the same time and will be transported to different places. Very rarely will parties interact with another.
Just as humans have coveted other nations or other lands, so too will other earths covet yours. Although the vast majority of the earth has been damaged by war, with technology and magic, the earth is in ideal condition for those whose planet is worse off.
For now, your planet is safe from experienced hunters and warriors, as well as stronger personnel from different places. This grace period will last for 3 years. Additional information will appear periodically: check your status window. Major announcements will be made by Me throughout this time. Lastly, a hero's monument will be set. If you choose to have your name acknowledged, it will show the top warriors. Major milestones may trigger a worldwide message. Cities who have over half their population at level 20 and above, will have their protection lifted. This means that they will be able to leave their region, and others will be able to enter it.
Good luck, and welcome to earth wars. May the best planet win." Throughout the entire explanation, the screen appeared to show multiple planets that look similar to ours, as well as all sorts of monsters. We were also able to see people who looked like humans wielding weapons, robots, and attacking or defending with weapons and or pets. We were also shown some of the gates where people were conducting experiments and creating weapons/ artifacts.
