Alex used Freezing arrows and attacked the monster. The freezing arrows exploded after reaching near the monsters and froze the surrounding places and things. The monster also got frozen for some time and Alex took out his sword and began to attack the monster fiercely. After few minutes the monster died and the exam ended. The man who was in charge of the exam and the receptionist who brought him here were both astonished and they were slightly afraid of what they saw. A high level A ranked adventurer can also defeat a B-ranked monster alone, but to defeat a B-rank,Boss monster within few minutes, it was even hard for them without any scrolls or strengthening potions. So they got understood that Alex was stronger than other A rank adventurers. Then the man gave the adventurer's card to Alex on which his class-swordsman class was written and another card on which his rank B was written and said that if he successfully completes 10 B rank quests and 1 A rank quest he can become A rank adventurer. The man also told Alex that if he wants he can upgrade his card to higher class like silver or gold class. By doing it he will get better treatments and advantage and he will become VIP of adventurer's guild. Alex agreed and paid required 2 gold coins and became Gold member of adventurers guild. The man took his previous B-rank card and gave him B-rank card which was made of gold and had the special sign of adventurer's guild which proved it is real. Alex saw it for some time and then put it inside his bracelet which was a important item for all adventurers as the bracelet contains dimensional space to store the things that the adventurer's going to need. Its also useful as one doesnt need to carry a bag to keep things and it also makes it easy to fight. One can buy those bracelet from adventurers guild. Then he turned back and slowly got out of the building.
