Since ancient times, I have stood here, and from the day I was born, I have guided my duty-to defend my country.

I am a wall, built by Qin Shihuang. Yes, I am a wall of the Great Wall in Wan Li. I built it with blood and sweat, so I have a soul.

I am a wall separating the two worlds. One day, a woman came to me and cried to me. Life and death are endless. It turns out that my birth is based on other people's lives! So I'm guilty! In that case, why should I live in this world? I collapsed ...

I don't know how long it took, but I was awakened again and I got a second life. I am like a phoenix, reborn from the fire. I know my duty is to protect my country and defend my country thousands of times. ...

When the Huns attacked, I was finally able to perform my duties. I blocked them with my strong chest. They were angry and shot at me crazily. It hurts! It hurts! But I will never compromise with them. I will do my duty.

Looking at the depressed back of Xiongnu, and looking at myself being black and blue, I smiled. I can finally atone for my sins and finally be worthy of heaven and earth!

I have witnessed the ups and downs of dynasties, the joys and sorrows of emperors and princes, similar flowers and different people every year, and I have some insights: everything has its own responsibilities when it comes to this world, but not all of them are vigorous events. Knowledge, like me, is an ordinary wall to defend the country, but I am not.

Don't expect immortality, don't expect the world to worship, just seek national stability and live up to your duties!

I am a wall, an ordinary wall, and I have some ideas about the future. ...

The ending is thought-provoking
