Tomb Raiding: I'm the Ultimate's Split Form

[This is NOT a story with two male leads!! It's about a female lead and a male lead!! That damned young lord keeps changing my tags! m9( ｀д´ )!!!!] [Original female lead x Xiao Ge, 1v1 slow-burn HE, Xiao Ge is the only one she loves. The plot has been changed. Starting from the very beginning, she will accompany Xiao Ge for his whole life.] [The female lead is beautiful, powerful, and tragic. Avoid if that's not your thing.] The author is a beginner, and the writing is average, so please bear with me. Don't scrutinize the logic; I'll do my best to make it reasonable. There are lots of original additions, so I don't recommend comparing it to the original or the TV series. No male-male romance here, just brotherly affection. Changing the original plot inevitably means OOC. The author is cold-hearted and may kill off a few side characters. If that bothers you, don't read. If you have questions, leave a comment and the author will make something up. If you insult me, I won't listen; it'll all bounce right back at you. Xiao Ge will eventually grow to 185 cm (my boy absolutely cannot be shorter than everyone else), and the female lead is 178 cm tall. One of the conditions Zhang Qiling had to meet to become clan leader was to enter the ancient building and find an antidote to the clan members' Heavenly Revelation. The antidote works on the clan members, but not the clan leader. The Zhang family is now beset by internal and external troubles, and its members all want to escape Heavenly Revelation and gain their freedom. The elders assume that the clan leader will shoulder the family's responsibilities. Zhang Qiling knows what they think but doesn't care. He only wants to know where he comes from and where he belongs. He will take responsibility for whatever he must. Only the clan leader may enter the Zhang family's ancient building. It has nine floors above and nine below, and records all the secrets the Zhang family has kept over several thousand years. But the family members don't know that the building actually has nineteen floors. Hidden underground is an unknown tenth level, one never mentioned in the Zhang family's records. Only the clan leaders of each generation know its secret, and it is passed down only among the clan leaders.
