You Said I’d Flunk Out and Become a Rich Heir, So How Did I Become a Martial God?

[A high-martial-world military novel + ensemble cast + love of country and family + intelligent characters + feel-good wish fulfillment + an ordinary man's rise + gradual progression, taking off in the middle and later stages. If that's not your thing, don't read.] He transmigrates to a high-martial world where everyone practices martial arts and ferocious beasts run rampant. Lu Hao becomes the son of a wealthy family, but because his predecessor had poor talent and was lazy and uneducated, he cannot even pass the martial arts preliminary trials. He thinks this is how he'll spend the rest of his life. He might as well just eat, wait, and die. But then he unexpectedly awakens the Strongest God of War System, which binds to him as soon as he joins the army. Lu Hao enlists without hesitation. No matter how much his father tries to stop him, he won't budge. Swing a blade ten thousand times, and he is rewarded with the Dragon-Slaying Blade of Breaking the Barbarians. Slay ten thousand ferocious beasts, and he is rewarded with a Saintly Embryo of Innate Dao Physique. Overwhelm countless prodigies, and he is rewarded with Supreme Bones and Double Pupils. Pacify a forbidden zone, and he is rewarded with the Great Dao made manifest. So, years later, when foreign races tear open the dimensional barrier and launch a full-scale invasion, a peerless martial god of the mortal world stands beyond the gates of Great Xia, clad in the Emperor's battle robes, wielding the Dragon-Slaying Blade of Breaking the Barbarians, and treading upon the sun, moon, and stars. Where I stand becomes a forbidden zone!
