The spring cold is precipitous, Chu Yun, who is already dressed in spring clothes, walked out of the exit of the Beiping Railway Station lightly, the cold air of early spring dyed her cheeks with a faint flush, and the tip of her pretty nose was frozen red.

Looking at the bustling crowd in front of him, a fluctuating heart was hidden under his calm and indifferent expression.

It's been two years, and the enthusiastic and childish female college student who left Beiping two years ago is now a full-fledged intelligence officer of the Northern Operations Group of the Military Command.

Two years of unusual experience made Chu Yun change not only his childish appearance, but also courage and perseverance.

At this moment, she stood calmly outside the Beiping Railway Station, which had been occupied by the Japanese, without the slightest timidity in her heart. She clearly knew that in the endless flow of people around her, there were many Japanese spies and plainclothes spies, and the slightest mistake in her every move would bring death to herself.

She calmly and quietly stretched out her hand to stop a rickshaw, raised her legs to get into the car, and ordered: "Go to Fuyou Street." ”

"Okay." The rickshaw driver pulled up the cart and ran as fast as he could.

The streets of Beiping are still the same as they were, the ancient city walls, the shops on both sides of the streets, everything seems to be the same as yesterday, but Chu Yun always feels that something is different from the past, as if something is missing. The car turned into a spacious street, Chu Yun recognized that this was Fuyou Avenue leading to the Xiao family's old house, and there was a stall selling rock sugar gourds at the mouth of the alley, with viscous syrup rolling in a large iron pot, and a layer of fragrant sesame seeds sprinkled on a clean board. His sugar gourd is particularly delicious, Chu Yun used to pass by here after school, and often couldn't help but buy a bunch and eat it while walking.

Chu Yun opened her eyes wide and looked all over the street, but she couldn't find the stall selling rock sugar gourds, and she suddenly understood that the Beiping in front of her was different from before. In the past, in Beiping, on both sides of the streets and in the alleys, you could see vendors selling all kinds of things everywhere, and there was an endless stream of people coming in and out of the shops. But right now, all the way from the station, Chu Yun only saw a few sporadic hawkers, the shops on both sides of the street were wide open, and the people who could enter and exit were sparse, and the whole Beiping was in a depressed scene.

Chu Yun sat silently in the car, quietly looking at the shops and pedestrians flashing in front of him.

Beiping has changed, it has become lifeless, and it has lost its unique spirit and spirit.

Getting closer and closer to the Xiao family's old mansion, Chu Yun's heart was beating faster and faster.

It's been two years, and Chu Yun hasn't gotten any news about the Xiao Mansion in the past two years, and she herself only wrote a letter to her eldest brother Xiao Yixuan when she first arrived in Changsha to report her safety, and she has never been in contact with the Xiao family since. But she did not forget them in her heart, that it was the home where she had lived for four years, that there were traces of her mother's life, that there were people who had given her sincere love and care, that she loved very much, but that she did not want to cause them any danger or trouble because of herself.

Today, Chu Yun has returned to the Xiao family with a major mission, and she will use the identity of the eldest lady of the Xiao family as a cover to establish an underground intelligence network in Beiping to assist the Northern Action Group in carrying out the underground struggle against the enemy.

This was a difficult task given to her by the Northern Operations Group after two years of training and practical training and the test of life and death.
