Sky was gloomy as doomsday has fallen on Earth.People were running here and there.Surrounding and the buildings were all destroyed part.Some were looking through rumbles of debris for the remains of their loved ones.

A few days ago,a giant asteroid came crashing on Earth.Many people died where the asteroid fell and surrounding its radius everything came hell like existence.The asteroid began to change into some kind of tree connecting Earth and the Sky.

Since then many space rift were opened all over the Earth.Monsters and other races came to Earth.Intelligent races were friendly towards human as for monsters.They were killing and destroying everything they saw.Later Humans find out that the space rift were called Dungeons.

After contacting with other friendly races,human began to know what they were going through.The tree which connected Earth and the Sky was called 'Tree of life'.

Opening of the dungeons was boon and bane to humankind.Due to opening of the dungeon, mana spilled out from the dungeon changing Earth.Earth size gradually increased.Now it's size was comparable to Jupiter and Saturn.

Monsters were hard to defeat even with modern cold machine.After some time people began to awake,every awaken person had game like panel.System holders began to fight against the monsters and established friendly with other races.

Later the system holders were called hunters.Economy began to change as well as judiciary system.Hunters became the main profession all over the world.

After unknown time has passed.

A young man was carrying a large bag filled with ration,potion and some weapons. In-front of the him was a group of people wearing medieval style of Armour and holding staff and swords fighting monsters.

Yes,they were inside of a dungeon.As the group of hunters defeated the monsters.A crystal dropped.The crystal were main source of hunters to level up.

After defeating the monsters,there was a chance of dropping items or crystals. Mana stone became precious to human not only it was Eco friendly it was also long lasting than nuclear power.

Nowadays everything used mana stone as a source of power.

As the group of hunters and a porter going forward clearing the dungeon.They finally came in-front of a giant door.

"Listen up everyone.After we defeat the boss ,we are going to have a feast."A blunt and tall man ahead of the group said.

"Captain i want beef"

"Captain i want fish"

"You guys only think about meat stuff. Captain i want to drink until morning."

Everybody was laughing and saying to their heart contained,except one.After defeating the boss.A round alter gradually made its appearance,touching the orb in the alter,everybody was teleport-ed back to the entrance of the dungeon.After everybody appeared in front of the dungeon,the dungeon began to shake and disappeared.

The captain walked toward Lycan and smiled.

"Today we had a huge harvest,so i am giving you extra."

Saying that he took out a crystal and placed in the hands of Lycan.

Taking the crystal. A blue screen appeared before Lycan.

'Do you wish to absorb mana stone.'

Not believing his eyes he rubbed them and slowly opened them.But there was still a blue screen.

"Boss,I feel tired today.As i am not awaken.I dont have stamina and strength as hunters.So i will pass."

Then Lycan began to ran towards his apartment.
