I Am the God of War of Daqian, and I Awaken an Invincible System from the Start

In the thirtieth year of Tianwu, the northern barbarians' iron hooves trample through Yanmen Pass, leaving a trail of slaughter and pillage as if no one could stop them. At the Great Qian court, the eunuch faction known as the Eastern Depot holds sway, civil officials form cliques for private gain, loyal generals are framed and exiled, and the dynasty teeters on the brink of collapse! I, Lin Chen, am a good-for-nothing branch-family member of the Lin clan in Tianqi City, living off others. But on my fifteenth birthday, I unexpectedly awaken the [Invincible God of War System] in the ruins of my ancestral shrine! “Ding! Beginner's gift pack: Nine Revolutions Dragon-Elephant Art, Sky-Piercing Spearmanship, and a massive boost to strength, agility, and constitution!” A good-for-nothing? That's all in the past! I master any cultivation art or martial technique in an instant, and send any enemy who comes my way flying with a single punch! Ahead of me lies the ferocity of a million northern barbarian soldiers. Behind me are the layers of murderous schemes plotted by eunuchs, treacherous ministers, and ambitious princes in Tianqi City. And at my side are... Su Qingmei, a spirited, fiery daughter of a military family who chases me around, swinging her silver spear; Lin Yuwei, an unmatched genius whose abacus clicks away as she schemes, yet treats me with tender affection; Ye Lingshuang, a mysterious, bewitching enchantress of the jianghu who loves pricking me with poisoned needles, yet protects me from the shadows... Watch as I, Lin Chen, defy the heavens with the System and blaze my way to victory! I dish out face-slapping to everyone who dares defy me, win the hearts of beauties of every kind, and pluck enemy generals from amidst a hundred thousand troops as easily as taking something from a bag. I'll topple the rotten court, destroy the northern barbarian threat, and build a foundation for Great Qian to last ten thousand generations, becoming the God of War who makes the world tremble!
