Chen Weiwan raised an eyebrow, her fingertips stained with tea drew circles on the table: "That's nothing. Later, we tricked the envoys from Southern Chu. They thought the 'friendship powder' we gave them was a beauty product, but it ended up itching all over their faces. Instead, they wrote to thank us, saying that their chronic illness had been cured. We tricked the old emperor. His children gave him chili milk cakes as birthday gifts. Now His Majesty hides when he sees our dim sum, saying, 'I am not worthy of the delicacies of the Prince's Mansion.' The most amazing thing is that we created a commercial empire. Merchants from Western Shu rushed to order our 'honest laxative', saying, 'If you take it and stop lying, all business will go smoothly!'"

"Mother!" Kengkeng suddenly stood up, his voice full of excitement, "I'm going to scam people all over the world and make Dasheng's croton powder famous!"

Shen Weiwan reached out and ruffled his hair, and powder fell on his collar: "Okay! But remember -" She suddenly frowned, but there was a smile in her eyes, "When cheating people, you must be moral. Only cheat bad guys and liars, and don't bully honest people!"

[Section 3: A Stupid Life, a Hole in the Wall to Create Happiness]

The midnight gong rang, and the guests gradually dispersed. Shen Weiwan and Xiao Yu sat side by side on the academy's highest point, the Stargazing Tower. Beneath their feet lay the sleeping croton fields, their sweet aroma wafting in the breeze.

"Your Highness," Shen Weiwan leaned her head on his shoulder, looking at the starry sky, "Tell me, have I turned the word 'sand sculpture' into a classic?"

Xiao Yu chuckled softly, tightening his arm around her waist. "This is unprecedented and will never be repeated. From the incompetent daughter of a general to the treacherous princess of a prince's mansion, and now the dean of the academy, only you can turn treacherous people into a livelihood that benefits the people."

"In this life," Chen Weiwan counted on her fingers, "I tricked the Liu family away and saved the general's estate; I tricked the scumbag away and brought in you, my beloved prince; I also tricked out three debt collectors..." She looked at the lights coming from her children's rooms in the distance, tenderness in her eyes, "It's worth it, it's really worth it. I used to think I was reborn for revenge, but later I realized it was to meet you and live this lively life."

"It's more than just the days," Xiao Yu held her hand, his fingertips tracing the calluses on her palm—marks left by years of grinding croton powder. "You've also created a peaceful and prosperous era. Everyone knows that with the Prince's Palace in Dasheng, scammers have to avoid it. Even street kids know to avoid anyone from the Prince's Palace, especially the princess who gives croton powder as a gift."

The two men smiled at each other. The wind from the croton fields blew through the observatory's railings, tinkling the croton wind chimes on the porch. In the distance, the sounds of Keng Keng and Wa Wa arguing came, as if competing to see who could produce the biggest smile with croton powder.

"In the future," Shen Weiwan stood up, the moonlight gilding her skirt with a silver edge, "this academy must be run well. We must teach the children to identify scams, and also teach them to use their intelligence to protect themselves. They don't necessarily have to cheat others, but at least they can't be cheated by others."

Xiao Yu then stood up and hugged her from behind, resting his chin on the top of her head: "I'll do as you say. My treacherous dean, what are you going to talk about in the first class tomorrow?"

"Just tell me..." Shen Weiwan rolled her eyes, and the corners of her mouth raised the familiar arc of "asking for a beating", "Just tell me how to use croton powder to make a simple lie detector, and give the new students a surprise!"

[Section 4: The legend continues, but the pitfalls continue]

The next morning, the rising sun gilded the plaque that read "Scam Academy." Shen Weiwan stood at the academy gate, watching the stream of children pouring in with their croton wood backpacks. These were adorned with all sorts of "anti-fraud artifacts"—some with sachets of itching powder, others with croton thorn bracelets. The most outrageous thing was the young master, who had hollowed out yesterday's "surprise winter melon" and made it into a schoolbag.

Henkeng, holding his "Super Itch Powder 2.0," and Wawa, waving his leaky "honesty flag," were arguing fiercely over who would be at the front of the line. Xiao Yu approached with two cups of croton flower tea. Seeing the sly smile in his wife's eyes, he shook his head helplessly. "Let's go, Madam Dean. You'll be late for your first class."

Shen Weiwan took the teacup, rubbing her fingertips over the croton powder foam on the rim of the cup, and watching the silver hair on her husband's temples gleam in the morning light: "Your Highness, do you think that when we are old, will our children's children come up with more fancy tricks to trick people? For example, using croton powder to make traps to catch thieves?"

"Of course I will," Xiao Yu pinched her cheek and said firmly, "It's up to you."

The two walked side by side into the academy. Sunlight filtered through the croton-shaped windows, casting flickering spots of light on the blue bricks. The classroom was filled with the noise of children, mingling with arguments about things like "Don't use too much itching powder" and "Honest Laxatives taste better with Sophora japonica honey."

Shen Weiwan's legend began with her rebirth in the autumn of her fifteenth year. Using her witty wisdom, she slashed through the shadows of her past life and lived a brilliant present. She relied not on scheming or witchcraft, but simply on straightforward, down-to-earth tactics and deception, protecting those she wanted to protect and winning the life she desired.

At this moment, she stood in front of the classroom door, looking at the energetic little faces in the classroom, with a satisfied and silly smile on her face. In this life, Shen Weiwan had cheated her enemies, cheated liars, cheated the emperor, and even cheated her family into happiness.

This legend, written with croton powder and laughter, has just begun a new chapter. On the road of deceiving people, she and her family will continue to move forward with their unique wisdom of sand sculptures of the Dasheng Dynasty, making every scam in the world invisible to their art of "deceiving people".
