Two Systems Connect All Worlds, Leaving the Ancients Stunned

The male lead, Lin Feng, unexpectedly gains an all-purpose System and a history livestream System, together known as the Twin Systems. Lin Feng finds Wu Shanshan, a girl who has just graduated and has little experience of the world, and the fun begins. A sky screen suddenly appears across countless worlds. What will historical figures of old, emperors, generals, and ministers do when they learn the truth about what lies ahead? What? The Hu will bring down Qin? My Great Qin will last only two generations? The First Emperor flies into a rage: Hu Hai! Come feel a father's love! Liu Bang: My Great Han has ruled for four hundred years. That's enough! Cao Cao of the Three Kingdoms: Sima Yi is stealing the fruits of my labor and usurping Wei? Liu Bei: Shu Han has fallen? We still failed to restore the Han dynasty? Sun Quan: The Three Kingdoms are reunited under Jin, and Eastern Wu has fallen? Great Sui: Yang Guang, Emperor Yang of Sui? The dynasty fell after only two generations? Yang Jian is so furious he faints. Great Tang: Wu Zhou replaces Tang? An empress? Li Shimin: Which unfilial descendant lost our empire? Song: A weak Song! A humiliated Song! Zhao Kuangyin, where's my dragon-patterned cudgel? I'll beat some sense into those unfilial descendants! Yuan: Mighty Yuan! Less than a hundred years? Kublai Khan: Impossible! Ming: The vigorous Ming! So many bizarre emperors! Zhu Yuanzhang: Let me see just how strange they are. I'll chop off their heads! Qing: The enslaved Qing! A century of humiliation! Shunzhi and Kangxi: Our Great Qing has fallen! Famous ministers and generals: Who are the heroes of the ages? The Martial Sage? The Sage of Strategy? The Immortal of War? Who is the greatest emperor of all time? Who is a wise ruler? Who revives a dynasty? Who is a tyrant or a ruler who brings down his country? How many have been condemned through the ages? Who are the heroines of the ages? Who says women are inferior to men? The synopsis is unclear. Give it a try, and please don't complain if it's not for you!
