Western Fantasy Lord: Starting with More Children, More Blessings

[More Children, More Blessings + Multiple races + Multiple factions + Multiple heroines + Farming] He transmigrates to a Western fantasy continent and becomes a noble named Leo. The good news: This world is full of mysterious powers. The Godblessed awaken to strange abilities overnight, while others train in battle qi for years or study magic with painstaking dedication... The bad news: Leo was born frail and can't practice battle qi. His aptitude is mediocre, so he can't learn magic. His luck is poor, too: he has received no divine blessing and is just an ordinary person. His father is gravely ill, his mother is his stepmother, his siblings are eyeing him hungrily... He has no one to rely on. Fortunately, he has a panel called More Children, More Blessings, a virtuous wife, and a loyal knight, though his son is a little spoiled. Wait... Just as Leo is trying to console himself, a chill suddenly rises in his heart. His More Children, More Blessings panel... why isn't it doing anything? Doesn't he already have a son? (His soul transmigrated into another body; the son belongs to the original body.) PS: This book is also known as “Lord: I Get Cuckolded from the Start, So I Wreck the Whole World”.
