Traveling through the Pokémon world, Su Huan awakened the [Many Children, Many Blessings] system. He thought it was good news for the harem, but it turned out... This is a scam! Even Foolish Old Man Moves Mountains is so outrageous! Just when he was about to find a tree with a crooked neck and spend the rest of his life, the system suddenly popped up! Bite! High value (humanoid) genetic template detected... Gardevoir! [Warning: The target is about to die. Please perform genetic fusion with the host immediately to achieve 100% pregnancy! Damn it? So this is the correct usage? ! When Su Huan had a [deep genetic link] with the dying Gardevoir, the world changed! Congratulations! The descendants of the S+-class 'Psychic Royal Descendants' are being conceived! [The host receives bloodline feedback: mental power increases by 1000%! Awakening 'telepathy'! [The Ancestral Bloodline Template is being constructed... 5% Complete! From this moment on, Su Huan went completely crazy! Latias? Take it!
