Lengendary archer with a system

Karan was born in a village and he has no parents since birth and raised by his grandparents. For studying in university he has gone to nearby city and fell in love with a girl named Sameera in his 1st year. On valentine's day he confessed his love and been cruelly rejected with the name of money. But he doesn't know she also loves him deeply but because of her family status ,she has no other choice other than to reject him. In sadness he has gone back to his village, before sunset he has climbed the mountain near his village to enjoy sunset. When he is deciding to get down,he has Seen a cave with a tree blocking and thick bushes and he know this cave has been there for long time but the strangest thing is he can see bright glow coming from the cave now. When he thought to go into the cave to explore the light,his leg got slipped and he died a cruel death but the strangest thing is the brightness in the cave and the sun which is going down glowed brightly. The Karan soul which is going to heaven got obstructed and absorbed back into the cave. When he opens his eyes he saw a man glowing like sun and a armour and earrings on the ground. " Karan you got selected for a mission in another universe and your system will tell you everything about it slowly and you are not alone in this mission there is another person involved in this with you"after saying that he brought a glowing red bow from thin air and takes those armour and earrings and he throws them at me. When I saw my own body there is a glowing armour and earrings and that bow entered my eyes and disappeared after that my body got flying into a portal opened by the sun god. "Your girl sameera is the other person selected by the moon god and she will die today night and join you in this mission" laughingly sun god exclaims in Karan's mind before portal closes. After portal got closed, sun god thinks"can they complete the mission in that cultivation world where gods,demons,dragons, Phoenix's roam freely".
