Raymond, who traveled to the continent of Eorzea, thought he had obtained Long Aotian's script, but he obtained the only hidden talent at the beginning - "Symbiosis Contract". However, the effect of this contract was so outrageous that it made him want to cry: every time he heroically defeated a powerful enemy, completed a feat, or achieved a breakthrough, part of his own power would be permanently lost and randomly transferred to the nearby partner who had the highest favorable opinion of him! So, the worst adventure in history begins: beat down the three-headed dog of hell? Congratulations, your sword skill level is -1 and your squad knight's sword skill +10! Cracking the ancient maze? Sorry, your magic power limit is halved, and your elf teammates' magic power is doubled! Finally upgraded? Your strength, agility, and physique have all declined slightly, and your orc teammates' berserker-like abilities +1! Raymond's fighting path is a parabola from "potential new star" to "fighting five scum". But the strange thing is that as he becomes weaker and weaker, his team becomes stronger and stronger, and the eyes of his teammates look at him more and more brightly (full of desire and protectiveness for the "experience package")... "Boss, don't move! Leave this little monster to me!" "Captain, rest assured! Let's fight with damage!" "Brother can just take command! We will do the dirty work!" Raymond could only cry, sitting on the rocking chair, eating hot pot, singing songs, being dragged by a group of increasingly unfaithful teammates to win and become a legend. This is a (grieving and happy) fantasy story about "sacrifice" oneself, achieve teammates, and save the world at the same time.
