One Moo'r Plow - Chapter 1B2-: Awakening.

She was the Empire’s top-tier elite agent, skilled in both medicine and poison. One day, she transmigrated into the body of a foolish, mentally disabled, and hideously ugly waste. But when her soul entered, the Phoenix Maiden returned, shaking the heavens and the earth! Those who wronged her will be repaid a hundredfold. Those who insulted her will pay back a thousandfold. Call her useless? Wait and see what true genius in cultivation looks like. Call her a fool? Wait and see who the top-tier alchemist really is. Say no one wants her? Watch as the strongest man follows her everywhere. From now on, divine beasts and handsome men will walk by her side, and she’ll roam the heavens and earth as she pleases.‘Qingcheng, from now on, I’ll help you manage the household and raise our children. This world and I will belong to you!’ said the scheming man with a flattering smile.The woman coldly met his gaze and replied, ‘The world and its empire are within my grasp. Now, get lost!’

After dying, Chen Heng finds that he has transmigrated to an alternate reality: everything is the same, except the world is now a Wuxia world heavily influenced by martial arts! Not only this, he discovers that he has a Fantasy Simulator, from which he obtains rewards that make him incredibly powerful in his new reality as well. Martial arts, immortal cultivation, and overpowered abilities–all of this begins from a single simulation!

Yang Feng somehow transmigrated into a different world and received a legacy of an ‘ancient high tech’ family, which does not directly raise his power, but gives him the technology to build things which are way more advanced than the seemingly medieval world.

But to build something you need resources and energy. To receive resources you need strength. To gain strength you need knowledge. To gain knowledge you… need strength? or a background? Or maybe a fully armed army of high tech robots who aren’t afraid of death?

But is this legacy really for him to keep?

- Description from Novelupdates

The story revolves around Charles Karino, a Levaamu Empire mercenary aerial pilot who mans the twin seater reconnaissance seaplane Santa Cruz. One day, he receives a preposterous assignment: to fly solo over 12,000 kilometers of enemy waters to protect a girl named Fana del Moral. Fana happens to be the next in line to the empire’s throne and a girl possessing beauty “equal to 5,000 beams of light.”

This is a standalone book. There’s another series under the name “To Aru Hikuushi e no Koiuta” (Love Song for a Certain Pilot) set in the same world, but in a completely different place and with different characters.
