p1: After completing her modern-day mission, Tang Yuanzhu finally returns through time with the System. But when she gets back, “she” is confessing her feelings to a strange man.
“Miss Tang, you just said I have to marry... what?”
Tang Yuanzhu hurriedly let go of the other person's sleeve, then smoothed out the wrinkles she'd made in it.
“I meant you have to marry... marry my Big Yellow.”
Unable to think of a good excuse, Tang Yuanzhu blurted it out as she looked at the yellow guard dog dozing under the eaves.
The nobles from Liulan Garden and Plum Garden heard her and looked up in astonishment. Even Big Yellow, who had just been named, wagged his tail and glanced at them both.
p2:
Everyone in Chang'an knew that Tang Yuanzhu had changed her ways two years ago.
She had grown up with the Crown Prince, but then got entangled with the Second Young Master of the Minister of Works' household.
She went to such lengths that the whole city found out, breaking the Crown Prince's heart. He took command of an army and went to guard the northern frontier, where he had remained ever since.
Tang Yuanzhu thought: I'm innocent!
p3:
Tang Yuanzhu went to the modern world to complete a mission, and brought the System back with her.
She helped the people grow sweet potatoes and improved rice so they could eat their fill. She taught them to grow cotton so they could keep warm. She suggested building dams and postal stations...
After doing all sorts of good deeds that benefited the people and the country, she even became a female official.
One day, the emperor asked Tang Yuanzhu what reward she wanted. She knelt and made her request:
“Forgive my boldness, Your Majesty, but I wish to marry His Highness the Crown Prince.”
The emperor was momentarily lost in thought. He was fairly sure he had heard those words about two years earlier, when the Crown Prince had exchanged all his achievements for the right to say:
“Forgive your son for his boldness, Father. I ask to marry Miss Tang Yuanzhu of the Chancellor's household.”
