How Did I Become Taizu When I Signed In?

Liu Ran traveled to a world similar to the Spring and Autumn Period and the Warring States Period, but it was a martial world of the Spring and Autumn Period and the Warring States Period. And the saddest thing is that he traveled through time and became a eunuch. How can he survive? But luckily he also carried a sign-in system with him, a sign-in system that made him furious. "Ding! You realize it in your shame and anger and get the best chance to sign in." "Successfully signed in to obtain the Law of Heaven and Earth." Liu Ran was too aware of the consequences of wandering, so he made up his mind that he would never come out until he became a saint. But why do some bastards always force him? He doesn't want to show off! ! !
