The lord of a great country came to the countryside in the rain at night in order to persuade the peasant couple to agree to the marriage between their son and his only daughter. The dirt road was muddy, the wheels were slipping, and he could not move forward. He waded in the water with bare feet and pushed open a low and dilapidated wooden door... A few years later, the son-in-law's parents were kidnapped and beaten by hostile forces... Dozens of hostile forces came to besiege the big country. The national crisis was imminent. If you truly love one person in your life, a grown man, like a dragon walking shallowly in the night, when your family and country are in trouble, you will roar into the sky to protect your true love, no one else but me! ! !
