I Can Summon the Heroine

A miserable old man was walking on the street one day, saved a child by luck, met a divine dragon, and then traveled to another world with a heavy mission on his back. Perhaps out of God's mercy, the old man obtained the "Hero Summoning System" as soon as he woke up. And the people summoned by this system are all girls? ? He just feels that his cuckold career should be over! "Me! Gu Yingnan! I must be the king in this life! Lead my sister to charge! Dominate the continent!"
