After rebirth, I handed over my past life information to the country

Wang Xiao and Lin Ce sat in Fang Heng's house waiting for Li Nana to bring the food to their door.

Ten minutes passed, twenty minutes passed, thirty minutes passed, but Li Nana still didn't deliver the food to the door.

Wang Xiao couldn't sit still any longer, "Fang Heng, go ask Li Nana why she hasn't brought the food up yet?"

Fang Heng stroked his chin and said, "Did we get too much money today and spend all the money of the little spy? Is Li Nana angry?"

Lin Ce, "Isn't it just buying a few clothes? The little spy's wallet is too thin. He can't spend it easily. Don't the spies in TV dramas spend money casually?"

Fang Heng, "You said it was a TV show. There must not be so many in real life."

Wang Xiao, "Although it's not a lot, but it shouldn't be less than a thousand yuan."

"Being a spy is a dangerous job that requires you to put your head on the line. Their countries are all developed countries. They won't be reluctant to give them money, right?"

Fang Heng, "Or maybe Li Nana is just a small shrimp and worthless."

Wang Xiao nodded, "Thinking about it carefully, Li Nana should be a worthless shrimp."

"I don't want to cook. I'm an old lady now, so I can't be too tired. You two should figure out a way. Either you two cook, or go find Li Nana."

Fang Heng and Lin Ce looked at each other.

Lin Ce, "Fang Heng, Li Nana's target is you. If you go to her, she will definitely give you food."

Fang Heng stood up and said, "I'll go look for her. This little spy has no professionalism at all. He ignores his target person when he encounters a little setback."

Wang Xiao called Fang Heng from behind, "Be careful with your words. You are currently a somewhat introverted student."

Fang Heng waved his hand and opened the door. "I understand. You wait for my good news."

Fang Heng went downstairs, walked to Li Nana's door and knocked, "Nana, are you home?"

The door creaked open and Li Nana poked her head out, "Fang Heng, what do you want from me?"

Fang Heng rubbed his hands and said, "Well, Nana, I'm really sorry for making you spend money today."

"I have two hundred and fifty dollars here. I'll pay you back first, and I'll owe you the rest."

As he spoke, Fang Heng took out a two-hundred-and-fifty-yuan bill from his pocket and handed it to Li Nana.

Li Nana looked at Fang Heng lovingly, "Those are the clothes I bought for you. They are just a token of my appreciation. If you give me money, you are trampling on my kindness."

Fang Heng tried hard to suppress his blush, "Nana, how can I be so embarrassed?"

Li Nana looked at Fang Heng and said, "If you're sorry, could you do me a small favor?"

"You said, as long as I can help you, I will definitely help you."

"I heard that you are very good at math. I am very interested in math, physics and chemistry. Can I ask you for help if I have any questions?"

Fang Heng said nervously, "Sure."

Li Nana looked at Fang Heng with amusement, "I noticed that you were not nervous when talking to Gu Ning, but you were nervous when facing others. Is there something special about Gu Ning?"

Fang Heng rubbed his hands, "Nana, Gu Ning is my classmate, that one is different."

She is a class leader, and our teachers always like to ask her to collect homework. As time goes by, we become more familiar with her than other students. "

"She has a lot of snacks at home, and she often brings them to school and gives them to the students in our class."

"I also ate a lot of snacks from her house."

Li Nana suddenly realized, "So that's it! I thought she was special in your mind."

Fang Heng covered his stomach.

"Fang Heng, what's wrong with you? Are you feeling sick?"

"I forgot to buy groceries. My uncle and aunt also forgot to buy groceries when they were shopping. I'm hungry!"

Li Nana, "You haven't eaten yet, come into my house and eat."

"I'm not used to eating at other people's homes."

Li Nana was stunned for a moment, then chuckled, "Wait a minute, I'll get you something to eat."

After saying that, Li Nana turned around and walked into the room. After a while, she took out a few bags and said, "Here are some dishes I cooked for lunch. Take them and eat with your uncle and aunt."

Fang Heng took the bag and looked at Li Nana gratefully, "Thank you, Nana."

"You're welcome, we are friends." Li Nana smiled.

"Thank you." Fang Heng thanked him again, then took the bag and returned to the room.

Wang Xiao and Lin Ce saw Fang Heng coming back and surrounded him. "How's it going? Did you get the food?"

Fang Heng nodded and handed the bag in his hand to them, "I got it. Li Nana gave it to me."

"Great, I finally have something to eat." Wang Xiao happily took the bag, put the food on the plate, and started to devour it.

Lin Ce looked at Fang Heng and asked, "What did you say to Li Nana? Why is she so kind?"

Fang Heng shrugged. "I just said I was hungry, and then she brought me food. Maybe she thought we were already friends."

"Fang Heng, your character has not collapsed, right? You must not reveal your true nature." Lin Ce said with a smile.

Fang Heng smiled and said, "Don't worry, I know what I'm doing!"

Wang Xiao, "Do you two want to eat? If you don't, I'll buy it all."

Lin Ce quickly took a bite of the food and said, "Are you a pig? You can eat so much."

Fang Heng also took a bite of rice. "Li Nana just told me that she is very interested in mathematics, physics and chemistry, and she wants to ask me questions in this area."

Wang Xiao, "The little spy revealed her true colors so quickly. She wanted to test whether you are the designer of the weapon."

Fang Heng gently put down his bowl and chopsticks, a cunning light flashed in his eyes, and he tilted his head slightly, as if thinking about how to respond.

"You're right, Wang Xiao." He spoke slowly, "This Li Nana is indeed not simple. She must have doubts about my identity."

"But since she made such a request, I can't just refuse directly, otherwise it will only arouse her suspicion."

"Then what are you going to do?" Wang Xiao frowned, worried that Fang Heng would reveal a flaw.

"I will discuss some basic math problems with her without touching on any core aspects of weapon design," Fang Heng explained. "This will satisfy her curiosity without revealing our secrets."

Wang Xiao nodded in agreement. "That's a good idea. But you have to be careful not to let her trick you into getting any useful information."

Fang Heng smiled and said confidently: "Don't worry, I will be careful."

"After all, I'm also an experienced agent. She won't see through me so easily."

In the next few days, every time it was time for dinner, Li Nana would bring the prepared meals upstairs to find Fang Heng, and every time there would be Fang Heng's favorite braised pork trotters.

Li Nana would take out exercises and ask Fang Heng for help from time to time.

Most of the questions she asked were about basic mathematics and physics, and Fang Heng cleverly avoided anything related to weapon design.

Li Nana didn't seem to notice anything unusual. She admired Fang Heng's knowledge and insights, and gradually put aside her doubts about him.

However, Fang Heng, Wang Xiao and Lin Ce all knew that this was only a temporary calm.

They must continue to remain vigilant to prevent any accidents from happening.
