Nine years ago, he was betrayed while performing a top-secret mission. He was shot seven times and escaped by jumping off a cliff. When he tried his best to climb to an alley, he was exhausted.
It was a girl wearing a shabby cotton-padded jacket, squatting in front of him. After hesitating for a long time, she broke off the half piece of sesame seed cake in her hand and stuffed it into his mouth.
"You eat it," she said, "It won't hurt anymore."
That half piece of sesame seed cake saved his life.
Later he found out that it was the anniversary of her father's death and she had just returned from the cemetery. It was her daily food.
He asked her name and she said her name was Shen Nianxue.
"Wait until I come back," he said.
But when he returned from his injury, the girl had already disappeared into the sea of people. He used all his strength to search across thousands of mountains and rivers, and finally found her - the eldest daughter of the Shen family in Jiangcheng, a down-and-out daughter who was being forced into marriage by her family, humiliated by her fiancé, and blocked by her creditors.
She didn't recognize him.
On that snowy night nine years ago, his face was covered in blood and he was dying. She only remembered those eyes. But the man standing in front of her now, his eyes were as calm as water, not even half as sharp as before.
"I would like to join the Shen family, work hard and do anything." He said, "As long as you give me a bite to eat."
Shen Nianxue looked at his old washed shirt and thought he was a desperate wage earner. She felt soft and nodded.
From then on, the legendary Dragon King who shocked the northern border became the most humble son-in-law of the Shen family.
