Starting in the Northern Song, I Build a Clan That Lasts a Thousand Years

His soul travels back to the Northern Song dynasty, where he becomes Li Qing, a lowly concubine-born son. His father doesn't care for him, his mother doesn't love him, and his family is on the verge of ruin. Is he about to starve to death in the streets? At this critical moment, the [Millennium Aristocratic Clan-Building System] activates! [“Newbie Quest: Earn your first 10 strings of cash within three days. Reward: +10 family fortune, x1 physique-enhancing serum!”] From the start, all he has is a bowl. His wealth depends on... uh, the System! “Potential heir detected! Invest in him, and he could become a powerful lord, ennobled and appointed chancellor!” “Warning! Your family will face total disaster in three days. Host, take evasive action immediately!” [“Congratulations, Host! You have successfully averted disaster. Family reputation +500. You have gained the ‘Turn Danger into Safety’ trait! Heir loyalty: MAX!”] I, Li Qing, will invest in the future and make my family prosper with this heaven-defying System! What? An enemy nation is invading? The Jin army is marching south? What a joke! My Li clan's sons are already everywhere in the court, and we have a million troops ready to descend like divine soldiers! Money, power, beauties... I want it all! Watch me build an immortal clan that will span a thousand years in this turbulent Northern Song dynasty! Whoever dares oppose the Li clan will be wiped out! The family's prosperity skyrockets every day!
