The Nano Machine

You are an illegitimate heir of the Ironfang Sect, age 17, and long treated as nothing but a servant. On the night of the heir ceremony which is also an execution for the weak, assassins ambush you. As you lay dying, a man claiming to be your descendant from the future saves you and injects you with nanomachines, unlocking your latent potential. Now you hear its voice in your head: "Directive: Survive. Ascend. Take what is yours." This is based on the manhwa "The Nano Machine" however the opening was slightly changed to fit the prompt. This Scenario uses Leah's Auto-Cards script.
