Luther answered to the Arthur's question,
"Listen carefully. In this world the Dungeons are the most important things for adventurers and most of the adventurers make their fortune from the Dungeons only. In this world the evil thoughts of every being is absorbed by this world which everyone call 'Gaia'. Then Gaia concentrate this evil power into a single point. If the single point becomes large enough then a dungeon emerges from there and the living beings have to regularly clear the dungeons. Otherwise dungeon break will occur and it will be worst calamity because all the monsters from all floors come at once."
"Normally dungeons contains 100 floors and if we clear level 1 regularly it will be enough but the power of level 1 monsters increases slowly. There are very few people who cleared all the levels of dungeons. And mainly they are all present demon lords of their own realms in the demon world."
"In the entire dungeon there are 2 rest floors(because adventurers can take rest there) one is at 40th floor and other one is at 80th floor. And if you are lucky then you can find some food or herbs or even some shops which sells different things there."
"That's all I know about the dungeons. This is the only information my grandfather gave me before I left my village."
"Hope it will help you and one last thing please sign a contract with me that you will give all your artifacts to me and we will distribute the profits in '50 50' ratio."
"What is your answer?"
After listening every word of Luther, Arthur deeply thinks for some time. In the mean time, Luther again requests Arthur, "Please '40 60' also works for me. Please accept it."
Arthur smiles and says, "Ok, Let keep it at '50 50' only." Luther rejoices and places a contract in front of Arthur and says "Then sign this contract."
Arthur was amazed and asks, "You have already prepared a contract." Luther replies, "I always works in advance. Only in that way 'I can become the most successful business man in this world.' "
Arthur smiles and sign the contract without any second thought. After collecting the contract Luther says, "You may be tired from your journey and rest for today and tomorrow you can visit nearby dungeon."
Arthur nods his head and says, "Thank you for your help." Luther replies, "It's ok. And I think you need money to stay and to enter in dungeon tomorrow."
Luther took some money and a ring from his bag and gave it to Arthur. The he says, "This is a small gift I am offering you for this contract and use this money to book a room in inn and enter a dungeon. This ring is a dimension pocket. It can store upto 50 things, so use it well."
Both of them bows towards each other and leaves the bar and went in two different directions.
As Luther said, Arthur rested for that day and in next morning he check out from inn. Before leaving inn he asked the way to reach the dungeon from inn owner and left the town for his first dungeon.
After reaching dungeon he saw many people at the entrance of dungeon. Some people are announcing the requirements to join their team. Some people are selling artifacts there.
Arthur slowly moving forward watches the large entrance door of dungeon and on the side there are people in queue paying entrance fees and waiting for their turns to enter the dungeon.
Finally Arthur's time has come.
The person(gateman )who is collecting entry fee asked Arthur, "How much people are in Arthur's team?" Arthur replies "I am alone." Then the gateman asks, "Is it your first time to enter a dungeon?" Arthur replies, "Yes." Then gateman asks, "What is your name?" Arthur replies, "It is Arthur Ischyros." The gateman wrote his name in a sheet, by folding the sheet he dropped it in a hole of the dungeon. He finally said best of luck to Arthur.
Then Arthur asked, "How many days it normally takes to clear the complete dungeon?"
