Just as the user Speedwagon said, the top left of the screen did have a filter option.

[Earth], [Moorim], [Seheranbad], [Kylian].

Whatare there different dimensions?

He wasnt sure, but Yoon-seok couldnt leave any possibility unchecked, so he started to look them over. He searched specifically for the Speedwagons messages. Suddenly, the whole messy chat room disappeared, and the messages by Speedwagon came into view.

Speedwagon: This place is called The Tower of Heaven, and it has four trials. The one you have chosen is called the Arena, the world of duels.

Yoon-seok absorbed the information that this unknown source offered.

We, the challengers, must fight an equal opponent every 24-hours. The basis for equality is based on experience, i.e., the total AP acquired by both parties.

In case of victory, you can buy equipment, learn skills, or increase your abilities using the AP obtained as a reward. Just like in a game.

In case of defeat, a coin will be used to revive. A challenger can revive themselves till their coin count reaches zero.

*Additional information, the price of a coin is 250 AP per unit.

The winner of the first duel will be rewarded with 2000 AP, while the loser will receive 1000 AP.

Returning to your world is simple one can buy a ticket from the Miscellaneous section. However, to waste your AP on an F-rank ticket right now would be suicidal.

It would be better to buy good equipment compatible with your unique skills rather than wasting points on improving the stats.

The last bit of information was crucial for Yoon-seok.

-Speedwagon: Thats it, thats all I know. I dont have any other information because Im just a first-floor loser, too. So, peace out!

That was his last message, and with that, the explanation was over. It was just a brief explanation, but for the clueless Yoon-seok, it was immeasurably helpful. He felt satisfied with the results of his curiosity. Now, he had to organize the information he obtained.

At least now, I have some information on this system.

The Tower of Heaven.

And what was the other thing, Arena, was it? The ordeal of Dueling.

If what Speedwagon said was correct, this place had a lot of game elements to it.

But, who made this place, and for what purpose?

No one knew at this point. Perhaps, its existence was divine, something that human beings couldnt comprehend. Now that Yoon-seok knew how to use the filter, he filtered out the messages from the challengers from Earth.

-Where_the_fuck?: Speedwagon! Please answer me. What should I do with my 1000AP?

-Kimchi dumplings: Ughbecause of kids like you, its getting noisy. Try using your brain!

-Where_the_fuck?: You idiot, block it if its getting loud.

-Where_the_fuck?: Speedwagon! Speedwagon!!!

It seems there were only 347 participants from Earth. Only a small number of people were talking, and most of the messages in the chatroom were chaotic. Seeing nothing important, Yoon-seok returned to the original screen, choosing the [Miscellaneous] option next.

stuff for sale in the Miscellaneous section, including convenience and other household items. It seems that even here, winning comes with a certain level of luxury. Soon, Yoon-seok found the Return ticket that Speedwagon mentioned.

*Re-ticket (Rank C) Tear the ticket, and you will be able to return to your original world.

Price: 200,000AP

The description is too simple simple enough to make me swear.

No matter what, he had to fight and repeatedly win to earn that much AP. Then, he found the F-ranked ticket that Speedwagon advised not to buy.

*Re-ticket (Rank F) Tear a ticket, and you will be able to return to the original world for 24 hours.

Price: 300AP

Currently, Yoon-seok had a total of 2000 AP. If he wished, he could return to his world at any moment.

But if I want to survive, for now, Ill have to endure it.

Even if he bought a few F-ranked tickets, the outcome would be the same. In the end, he would automatically be teleported back after a few days. Yoon-seok considered buying one F-rank ticket to see if they worked properly, but he decided to postpone it for the next time.

To return to Earth, even for just twenty-four hours? Thats good. But right now, the priority is survival.

Challengers had to save their AP to invest in equipment or perhaps to learn a skill. The more AP one had, the higher their chances of surviving. Yoon-seok returned to the home screen and chose [Equipment], where another list appeared.

[Weapons]

[Armor]

[Accessories]

[Special]

Among the categories, Yoon-seok chose [Weapons]. The screen then changed once more, revealing even more options.

[Daggers]

[Blunt weapons]

[Spears]

There has to be something like brass knuckles.

Yoon-seok defeated a monster with his bare fists, but that was only possible because his opponent didnt have a weapon, either.

Moreover, I still have no clue how I did that.

Right now, Yoon-seok needed weapons. There was a huge difference between fighting with bare knuckles and with equipment.

But what weapon would suit me the best?

He remembered a saying about how the longer the weapon one had, the more advantageous it was. Of course, the first one to stab had the best chance of winning.

If thats so, should I pick a spear?

Yoon-seok, feeling distressed, soon shook his head.

No, its better to pick a sword or a blunt weapon.

To handle a spear, he had to use both hands. He must not only think about the range. If it were only about range, then a bow would be the best weapon here.

I need a shield, too.

Yoon-seok imagined himself in a real fight with someone. He shuddered at the thought of wielding blades to kill someone. Also, was it possible to block an incoming sword with another blade, just like in those animated shows he had seen? It looked quite unrealistic. Rather, it seemed more stable to block attacks with a shield and wield a sword or blunt weapon in the other hand.

Well, Ill look around some more.

Soon, he found a sword. He checked the details written on the item.

Is this worth it?

*Black Longsword. (Rank F) Unnamed sword. Hard and sharp.

Price: 1000AP

A weapon with no special features. Magical and C-ranked weapons came with skills, but those weapons cost more than 100,000 AP.

I cant even access any item that is B-Rank and higher. Does that mean that my level has to be higher just to see them?

For now, Yoon-seok put the weapon purchase on hold and started to explore the other items. Though Speedwagon advised buying equipment first, he couldnt be sure that it wasnt malicious advice.

He only had 2000 AP. So, caution was necessary to make the most efficient purchase. Yoon-seok, having decided to spend a bit more time looking around, took almost an hour as he skimmed through every available option. Finally, he concluded.

Lets buy a sword and a shield.

To be honest, he felt scared about buying a sharp weapon. Just a little slip on his part, and he could injure himself with his blade. Also, to wield a sword, he must use a lot of force. Was it possible to wield a sword while holding a shield at the same time? Yoon-seok thought handling both a shield and a weapon might be possible if he was a bit stronger, butthat wasnt the case.

After scrolling for a while, he finally had a few weapons that he took into consideration.

*Frantal Court Sword (Rank F+) Dual-blade used by knights of the Frantal royal family.

Price: 1500AP

The shape of the sword was similar to that of a common rapier, about 120 cm in length. The sword was for quick slashing and stabbing, but it had a double-edged blade. Right now, this sword was perfect for Yoon-seok, based on its weight and length. It was light and could be comfortably used with one hand, while the length of its blade could grant him an advantage.

One flaw was that it wasnt as durable as the other swords, but Yoon-seok didnt mind that, as he had a unique skill to make up for it.

Enhanced Weapon. That skill could make his F+ weapon temporarily jump a level, making it E+. An E+ weapon costs at least 6000AP.

Your purchase has arrived.

Please check the lower part of the statue.

Just as the messages popped up, the stone statues pedestal opened like a drawer. From it, Yoon-seok took out the sword and a shield. He didnt even question how such a thing was possible; he wasnt curious at all.

Since Ive invested a lot in the sword, the shield came out a bit poor.

The F+ Ranked shield, purchased for 500 AP, was a simple round shield made of wood. Only its outer surface was lightly covered by iron. Because it wasnt fully made of iron, it wasnt particularly strong in defense, but having a lightweight shield brought him a mild sense of comfort.

Its lighter than I thought.

Yoon-seok took both the shield and the sword in his hands and began moving and swinging them around. Was he able to adjust because of his F- Ranked body? He knew it would have been quite difficult to move around if he was in his original body, but he didnt feel any restrictions on his movement due to their weight.

Unlike the other challengers who lost their strength due to being delegated to F-rank, Yoon-seok was originally weaker than an F-rank. Thus, it felt like a level-up.

Just in case, I should look at the chats.

He looked at the ongoing chat while his arms moved non-stop, practicing with his sword and shield. If he wanted to fight properly, he couldnt waste any time getting used to the sword and shield until they were like an extension of his limbs.

Block, thrust.

Yoon-seok needed to perfect the basics. He had a shield to protect him and a sword he could use to attack. He needed to be accustomed to using them.

As time passed, he realized something new.

Theres a reason why there are no toilets around here.

He didnt feel hungry. Also, no matter how much he sweat or how tired he grew from practicing, he would return to his normal state after waiting a bit. In other words, he could train as long as he wanted in this waiting room.

Next duel in 21:31:46.

Looking at the clock, Yoon-seok thought to himself.

I think this is the reason why the challengers are given twenty-four hours was to prepare for the next duel.

However, not all challengers thought like him.

-Wind_Wind_Wind: Oh God, so bored. Isnt this waiting time so annoying? Dont waste time. TIME IS GOLD~

-JWH904: There was a game machine in the miscellaneous items. Just bought it.

-Wind_Wind_Wind: That was 900AP. Id rather go home for three days than buy that.

-Snow White: Does anyone know whats happening on the Earth? With so many people going missing, they will surely investigate it, right?

Wind_Wind_Wind: Do you think the government could save us? Theres a whole bunch of other dimensions dragged into this.

-JWH904: Cant we change our skills? Mines a total mess.

Wind_Wind_Wind: What is it?

-JWH904: I wont tell you.

Yoon-seok filtered the chat room, limiting the users to only those who were from Earth. However, there was nothing helpful in the conversations that were happening. Some whined about the current situation, while others randomly talked about their lives on Earth. And a few of them talked about their last battle as if it was some sort of an epic saga.

Inside that stone chamber, without a smartphone, it was their way of killing time. But Yoon-seok was different.

Woosh-! Woosh-!

And after some point, he stopped looking at the chatroom altogether.

Thrust, cut, block

Yoon-seok concentrated on repeating those three actions.

Ha Ha

Yoon-seok was breathing heavily. Through an unknown process, his body recovered to its normal state every ten minutes or so. However, the amount of sweat on his body continued to increase. More and more drops of sweat started to swell up and drip down.

Slowly yet steadily, Yoon-seoks movements started to change.

The shield isnt just for blocking; I can also use it to attack.

He was currently exploring different ways to use his shield and the sword, determined to learn and prepare for the upcoming duel.

While slashing, the center of gravity must be on the lower half of the body.

Yoon-seok was getting used to this unfamiliar sword. Muscles that he had never put to use since he was born were all revealing themselves, one at a time. People used to say that every human had a gift, but only a few had the opportunity to make it bloom. If so, was this Yoon-seoks gift?

Breath slowly, let it out.

Despite having no one to teach him, Yoon-seok repeatedly slashed at the air. His clumsy movements gradually became sharper, more graceful.

Wind_Wind_Wind: I want to go home. Ill go next time!

In the chatroom, people were laughing, chatting, and spending their time senselessly. Meanwhile, a man who had lived his entire life without knowing he had talent was about to transform by honing his skills.
