The stones that had been smashed on it were swallowed up by the wall.

But the first explorers to go in still didn't return.

No one knows what happened to them inside, whether they were dead or alive no one knew.

But their disappearance could not dampen the enthusiasm of other adventure fanatics, and some of them went to that world together.

This time, before they left, the federal government equipped each of them with sophisticated weapons, ample food, and various protective equipment.

The "door" was only open for a day, and after the men left, it was unsurprisingly closed again.

With the experience of the last time, everyone is no longer so anxious, but quietly watching and waiting, just waiting for the "door" to open again.

Living up to expectations, on the seventeenth day, the "door" opened.

Someone came back.

Those who came back were the first to go in.

Covered with wounds, but he also brought back rare information from another world.

It is a pristine world unpolluted by humans.

There were terrible monsters everywhere, the smallest of them being two or three people tall, and the largest being the size of a mountain.

Human weapons don't work against them at all, they eat people, no, or they eat everything, some eat not only other species, but also their own kind, and humans are only enough to stuff their teeth.

He told the federal government about his experience.

As soon as he stepped into that world, he lost contact with his companions.

The door on the wall is just a portal that transports everyone who enters it to a different place.

He was sent to a valley surrounded by mountains and rivers, and he walked in it for a long time, a long way, and did not find his companions.

And the fully automatic high-tech equipment he was carrying also failed the moment he entered. The communicator didn't work, the sensor, the scanner didn't work, even the most primitive compass he carried with him didn't work.

All you can use is a camera and a gun.

Over the course of nearly two months, he encountered many monsters, monkeys with a dozen eyes, horned boars as tall as two stories, and pythons with dense legs......

Luckily, the giant monster looked down on him, a human who wasn't good enough to stuff his teeth, and didn't pay attention to him. Deadly are the small carnivores that are small in size and have been reduced to the food of giant carnivores.

In this world of giant beasts, human beings are like newborn babies, and all that comes is death.

He was able to come out of it really because of luck.

Of course, what he brought back was not all the horrors of another world.

And also: wealth.

Rich mineral resources, precious gold, silver and jade, and thousands of miles of fertile land are all reluctantly missed by the chaebols, who are in power in the federal government.

Is it a primitive world full of dangers and monsters?

No!

In the eyes of the chaebols, it is a kingdom of wealth that has not yet had time to conquer, and it is a hotbed that is about to nourish the rapid accumulation of their family's capital.

What if there are giant beasts, no matter how huge they are, after all, they are not invulnerable, and the elite soldiers of the federal government will definitely be able to level them.

Thus, this world has a name, "Threshold".

Next, the chaebols completely sealed off the area where the threshold was located, and ordered no one to approach the area on the grounds that the place was dangerous.

The purpose of the Federation in doing this is simply to monopolize all the treasures in the threshold, after all, most of the jewelry mined from the threshold will be bought at a high price for ordinary people in the future.
