Jin easily passed the 8th, 9th, 10th, 11th, 12th, 13th, 14th, 15th, and 16th floor and arrived inside a big wide room, the 17th floor.
The amount and size of the room in 8th to 9th floor increase and the length of the hallways between them became shorter. Also the ceiling changes height from three to four meters from the floors above to nearly ten meters above. Moss covered the brown colored walls and the ground below a short grass plain. No new monster appears here but, the kobolds and goblins are stronger than above floors.
In the 10th-12th floor... The 10th floor keeps the same structure as 8th and 9th floors above, however the light from above become a reminiscent of morning mist. Monster like Orc and Infant dragon started to appear here but, to Jin they were still weaklings. Silverback and Hard armored appear in floor 11th and 12th. The scenery is the same but the mist grew thicker.
The 13th to 17th floor are known as cave labyrinth. Starting from floor 13th the walls, ground, and ceiling become made of bedrock. The monster here are stronger than above. Jin guess that the monster here such as Minotaur could rival level 2 adventurers. Although Jin was level 1, he was completely different from the adventurers here in this world. Before receiving a falna his base power was already high.
Jin also earn a decent amount of points from killing all the monster he met on his way here to 17th floor. He only knew it because of the 99+ notification on his system. He killed more monster than he imagined and each monster gave him 30-50 points. For now he wouldn't looked at the exact amount he earn. He would take a look at it after he arrived at the 18th floor, also known as Rivira.
The 18th floor or Rivira is a safety point where no monster are born, though some monster can come up from the floor below. In that floor Jin decided that he would take a break for a while.
Jin walked forward and looked around at the big wide room of 17th floor. He then felt the ground shook slightly.
He looked ahead of him and saw a giant monster appeared. This was the monster he saw on anime, the Monster Rex Goliath.
The Monster Rex roared loudly and it shook the entire room.
"Can you stop yelling at me? It's hurting my ears you know!" Jin said as he started to walked towards the Monster Rex.
Jin smirked and said, "I wonder how many punches of mine can you take? Ten, twenty, or maybe thirty? I will not use any of my elements so it's a disadvantage for me but..." He then dashed towards the monster and threw himself at it.
Boom!
Jin jumped in the air as the ground below his feet form a crack due to his force. He arrived in front of the face of Monster Rex and he pulled back his fist.
"But I can use my magic power however I want. I will only not use it to cast the dragon slaying magic." Jin said as he threw a powerful punch containing immense magic power.
BOOM!!
The Monster Rex staggered back and crashed into the wall behind it. The Monster Rex still managed to throw it's fist despite crashing in the wall.
Swoosh!!
Jin looked at it and quickly knew that he couldn't dodge it as he was in mid air. He just crossed his arms in front of him and gathered his magic power at his arm to strengthen it.
Bang!!
The giant fist hit him and he was forcefully thrown back in the ground.
Boom!!
Jin crashed on the ground and it created a small pit.
"That pack some power." Jin said as he stood up and patted his clothes.
He once again dashed towards the Monster Rex. Jin arrived at it's feet and he throw a punch at it.
Bang!!
He then jump and kicked it's stomach.
Bang!! Bang!! Bang!!
Jin throw a barrage of punches. A flurry and Monster Rex couldn't even fight back.
"It's time to finish this." Jin said as he pulled back his right fist and he imbued a large amount of mana in his fist. His fist glow lightly as the mana gathered inside it.
He then threw at it at Monster Rex.
Swooosh!!
Boom!!
The Monster Rex face exploded as soon as his fist hit it's body. It turned into dust leaving a large crystal.
Jin looked at his fist. His base form was slightly weak, no, it was weak. Without using mana, skill, heavenly energy, and demon spirit, he was weak. His base form, just pure physical strength was lacking in some ways.
He couldn't even finish the Monster Rex with just a few punches with his pure physical strength. He know that he was strong if he added his magic power or mana as he could kill Monster Rex in just two or three punch with mana but, he still want to increase his physical strength.
"A body strengthening technique is what I wanted right now." Jin muttered. Well, his physical abilities will grow stronger too once he level up his adventurer level.
