Fortunately, Li Yundong solved the siege for her. Li Yundong said with a smile, "what hero?"

Cheng Cheng on the side saw that Feng Na's ears were red. Knowing that she was flustered, he immediately handed over the book in his arms and said with a smile: "you, great hero, come and sign! Now I officially become your No. 2 die hard fan!"

Li Yundong took the book, looked at it and said with a smile, "you take the economics textbook for me to sign? It's very insincere!"

Cheng Cheng spits out his tongue and smiles: "it's okay, just sign it!"

Li Yundong didn't refuse like before. He smiled, picked up his pen, opened the paper and signed a name on the title page. Feng Na on the side kept her eyes on Li Yundong's every move. She felt that the boy in front of her was suddenly mature and strange.

When Li Yundong handed the signed textbook to Cheng Cheng, Feng Na suddenly grabbed it, rolled it into a cylinder, gathered it in front of Li Yundong's mouth, and said solemnly, "Li Yundong, what did you think when you saved people?"

Li Yundong laughed: "what else can I think? I didn't think of anything!"

Feng Na smashed Li Yundong with her textbook and pretended to be angry: "as a hero of Tiannan University, how can you think nothing? Answer well!"

Although Li Yundong suddenly met major events and became more mature and stable, his character will not change after all. When he saw Feng Na's style, he also deliberately put on a straight face and said seriously: "at that moment, I thought of my motherland, the party and the people..."

Before he finished, Feng Na and Cheng Cheng couldn't hold their faces and laughed.

Feng Na smiled and said to Li Yundong, "thank God, you are still the guy I know!"

Li Yundong touched his cheek and said with a smile, "have I changed a lot?"

Feng Na looked at Li Yundong very seriously: "from the first time I knew you, you have changed so much and so fast! However, I still prefer to see your previous appearance, frank and cheerful, and laugh whenever I want."

Li Yundong laughed and said, "isn't that what I am now?"

Several people talked and laughed. When class was coming, Li Yundong saw that Feng Na and Cheng Cheng didn't mean to go. He asked curiously, "don't you have class today?"

Feng Na knew in her heart that Li Yundong was going to class and she should leave, but she wanted to go in her heart, but she seemed to have roots under her feet and buttocks, and her body couldn't move.

Cheng Cheng on one side helped her out again: "today we have a self-study class. Come to sophomore to review our previous lessons! Review the old and know the new!"

Li Yundong said with a smile: "really? But I think Feng Na has the style of being a reporter. You can consider this profession in the future!"

When Feng Na heard this, her face showed a surprised look: "really? Do you think so? I really had this idea!"

Li Yundong looked at Feng Na very seriously and said solemnly, "I'm polite. Don't take it seriously!"
