Zhang Ganyu lowered his voice and said, "This is the prescription I just got for treating abdominal effusion. This prescription is very rare, and I paid a high price for it. Next week is the day you will meet with them, so remember to say good things about me then."

"Know that we will never forget your contribution." The contact person also lowered his voice.

Upstairs, Xiao Zhang saw that Zhang Ganqi had handed the prescription to the contact person. If he didn't take action, the contact person would leave their blockade area, and then they would be in trouble!

But if we take action now, the contact person is holding a child. What if the child is hurt?

At this moment, Gu Shiqing had already poured all the soybeans in the bowl into his pocket, and then he made a quick gesture outside, meaning "get started!"

After receiving the signal, several people immediately took action.

However, the contact person was an old spy with a keen sense. When he found something wrong, he immediately took out the dagger on his waist, put the dagger to the child's neck, and cursed at Zhang Gan: "You useless thing, you didn't even know you were being followed!"

He threatened the soldiers in plain clothes: "Get out of my way! Get a bicycle ready! Otherwise I will kill him!"

The child was so frightened that he burst into tears. The candied haws fell to the ground, and the sugar juice melted and became sticky: "Wuwuwuwu, Daddy, Daddy, don't kill me..."

This child turned out to be the spy's son!

The spy was so crazy that he even spared his own son.

The soldiers did not dare to act rashly because they did not know whether the spies would really kill the child.

Zhang Ganqi was so scared that he collapsed to the ground, and the contact person dragged the child back to the alley.

At this moment, Gu Shiqing kicked open the wooden window and jumped down. He unbuttoned his shirt to reveal his military uniform, and the red five-star cap badge shone brightly in the twilight: "Release the child!"

The contact person's pupils suddenly shrank, and the dagger left a bloody mark: "If you come any closer, I will..."

Before he finished speaking, Gu Shiqing suddenly raised his hand, took something out of his pocket and threw it towards the contact person.

The contact person subconsciously swung his sword and chopped it, causing the fried soybeans to scatter all over the sky.

While his vision was blocked, Gu Shiqing rushed forward and grabbed his wrist, twisted the joint, and the dagger fell to the ground. The child was thrown towards Xiao Zhang who came over and landed in his open arms.

"Good!" The onlookers burst into cheers.

The contact person was still struggling, but Gu Shiqing kneed him in the lower back, pulled off his straw hat and tied his hands with it, his movements smooth and flowing.

Zhang Ganqi had been pressed to the ground by the soldiers, and his crotch was wet.

"Take them all away!" Gu Shiqing waved his hand and said to the soldier who was suppressing the two spies.

As for the child, he was naturally brought back to the army.

The iron door of the interrogation room slammed shut behind Gu Shiqing, and the damp and musty smell mixed with the scent of cheap tobacco hit him in the face.

Zhang Ganchen was handcuffed to a cast iron radiator, his forehead glistening with cold sweat under the pale light.

"Tell me about it." Gu Shiqing threw a stack of prescription copies on the iron table.

Zhang Ganyu shuddered, and the radiator clanged: "I, I'm just an errand boy! Wang Feihua said that these prescriptions should be used for national research..."

Wang Feihua is the name of the contact person.

"Think it over before you speak." Gu Shiqing knocked on the table to remind him, "Every word you say will be recorded. It depends on whether you confess yourself or use some tricks to confess."
