The future appears to be bright. But not in the real world. Environmental degradation is exacerbating the situation. That is why all of the world's leaders gathered and agreed to work together to solve this problem. Forests are replanted to cover the earth, and all human activity is concentrated in a city called the Gaia Union. The island formerly known as Borneo became the choice. Building on flat land without mountains is easy. The equator provides its own level of comfort.

A new issue arose before the city was finished. They're having troubles with the machine. The portal between dimensions appears to be wide open. The monsters arrived to prey on humans. As a result, half of humanity was wiped out.

Humans have been conducting research for many years. Until the discovery of acid rank, a liquid that can boost human abilities. The humans were a little overwhelmed and couldn't control it because they didn't know what level they were on. Then they made a glass level indicator. Humans can use this bracelet to determine the level of themselves and the objects around them, as well as the class they belong to. The bracelet can be used to identify skills and abilities.

The era of annihilation has given way to the era of hunting. The prey has evolved into a predator. Monsters are now considered research and asset commodities. There were also those who died while hunting at the time. Some people are terrified by this. During that time period, a hero with four classes appeared: warrior, tamer, archer, and magician. She is the hunter's mother and a role model for all hunters. She is known as Putri Bumi.

The defeat of the monsters did not immediately close the portal. Putri Bumi steps through a portal. There's a dungeon inside. His example was followed by the other hunters. However, many of them did not return. So they get together to enter a portal. Their number of members grew over time, and they eventually formed a guild.

Some of the portal's content is unknown. There was a shady transaction. Many people were sacrificed as a result of it. Human purchasing and selling is unavoidable. The government is not going to stand still. All dungeons have been overrun. Activities both inside and outside the house are meticulously documented. Hunting activities have been regulated since then.

The city's development was pushed back. To expedite the sale of all currently available dungeons. Come all the investors and wealthy individuals, including Putri Bumi's family. A 20% tax was imposed to begin with. The investors began setting their own rates and gained control of the majority of the guilds.

Time passes. High-level hunters are now getting richer. Guild owners, dungeon owners, and investors are becoming wealthier. They have little sway over the government. They had become royalty and had a large number of servants.

In contrast to low-level hunters, this was not the case. Many of them were killed in vain. He left an impoverished family behind. Their lives are adorned with misery. There are many people who sell themselves in order to survive. Human life in the new world is becoming increasingly complicated.
