Am I Invincible? You Told Me the System Is Coming

My name is Jiang Du, a pioneer who died suddenly after staying up late and traveled across time accidentally. Why do other time travelers have systems, but I don't! "The wind and snow have been weighing on me for two or three years, but I laugh that the wind and snow are as light as cotton! If Tongzi doesn't come, I will go alone." It doesn't matter if there is no system at all. "Hello, my name is Jiang Du, an ordinary person."
