I hope I can find a BL novel similar to these three : The Spiritual Plant Master Transmigration, The Transmigrated Li Jin’s Daily Farming Life or Begging You to Break Off This Engagement! A novel where the MC is a gong/ shou, has a family (mpreg maybe), does agriculture at the beginning (it is not necessary to do it throughout the novel). In addition, I would prefer that it was not in modern times, but rather a historical one with daily situations of those times or one related to cultivation and sects (not my main objective, but I also like them). It doesn't matter if it's not being translated. Sorry for the grammar.
秀才家的壮夫郎 The Xiucai (county scholar)'s Robust Husband- Gong MC, ancient times, Shou ML is a manly Ger who has amnesia and knows martial arts (MC is more thin type, he likes manly guys but of course manly and muscular Gers weren't as popular so shou wasn't used to MC's eagerness but it's sweet), has another subpairing with a chubby Ger who wants to have muscles and his friend, pretty slice-of-life, contains mpreg and body worship(?). He doesn't really do any farming himself (if I remember correctly), but he does contribute to improving the agricultural techniques and whatnot
There's also a sequel to it set in modern times with the same pairings if you end up liking it and want to read more. Iirc there's also extras with the sub-pairing, but I could be wrong (been a while since I read it).
The Only Favourite Ugly Husband- it's got similar genres, it has mpreg, historical, transmigration, farming, nation building
If you want to mtl, I have tonnes of novel links since I like reading those farming novels. Just find the one with ancient tag and see if you're interested https://forum.novelupdates.com/threads/bl-shonen-ai-yaoi-novels-recs.84327/ This is the example 145. https://www.translatetheweb.com/?ref=TVert&from=&to=en&a=https://m.shubaow.net/101/101411/ 农门科举之赚钱,考试,养家 Mtl title: Agricultural department to make money, examination, support the family Transmigration. Ancient. Mpreg. MC is seme. 173 chapters. MC somehow ended in ancient era while the original ended up in modern era. MC first made money from selling snacks and later continued to become scholar. Later MC became emperor's disciple and worked together to create a better country.
http://www.jjwxc.net/onebook.php?novelid=3554973 Farmhouse. Gong Mc. Farming, business, and imperial test (not the Gong tho). Transmigration, Mpreg. Drama. Didn't remember much, read it long time ago, but fairly entertaining. http://www.jjwxc.net/onebook.php?novelid=4137395 The Hero and The Villain are My Babies. Shou Mc. Cultivation, cooking, chasing a heartbroken wifey. Transmigration, Mpreg. DRAMA. Mc is a half demon/beast(?) (the children are simply cute istg), Ml is (was?) a scum but he is trying to be better. http://www.jjwxc.net/onebook.php?novelid=3250994 末穿古之夫父有为 (idk how to tl this, Responsible Hubby and Daddy smthng? My mandarin is as poor as me). Gong Mc. Transmigration, farming later joining military, Mpreg. Just started reading this but it is entertaining so far. Gong is a retired special unit soldier before transmigration. http://www.jjwxc.net/onebook.php?novelid=3702545 Farming in Another World to Make Money. Gong Mc. Transmigration, farming, imperial examination, Mpreg. Haven't read but from the summary it is quite promising. Sadly, I don't find much from the merge of said categories that keep my interest long enough. (but I do enjoy them immensely)
Can you please tell me where can I read the translated version of The Xiucai (county scholar)'s Robust Husband?
Banished to Another World (not historical, but it is ancient civilisation) - It does involve abilities so maybe not what you were looking for Transmigration of Mian [Reluctantly] Becomes His Man [Wife] Transmigrating to Ancient Times with Lu's Convenience My Favourite Manly Husband The Only Favourite Ugly Husband
