Benefactor

If this disease spreads, your species will perish.Please use my body to craft the serum.Use my life for the sake of your future.

We are deeply grateful;your dedication shall not be forgotten.In times to come,when your descendants struggle to survive,my descendants shall offer them blood.I trust this will repay our debt.

We thank you as well.When we take your blood,we will leave a sign of gratitude.We shall bite so it does not hurt,though a slight itch will remain.You humans and we mosquitoeswill be friends forever.
