The system said, "Host, there has been no war in Da Gan for the past twenty years, but the external environment is similar to that of Tang Dynasty on Earth. Nomadic tribes frequently invade the borders. Xiushan Village, where you are, is located in the central border region of the entire Dragon Kingdom. It is a small mountain village under the jurisdiction of Qingzhou in Da Gan. There are natural mountain ranges here as a barrier for the border. The capital of Da Gan is located in Luoyang."

Li Yao roughly calculated in her mind that, if she converted it to a map of the Dragon Kingdom, she would be in the northwest region, not far from Chang'an, while the capital was in Yuzhou, about a thousand kilometers away.

Li Yao asked, "System, do you have any background information about the princess being switched?"

System: [Host, yes, it's available for purchase. It costs 1000 skill points. Would you like to buy it?]

Li Yao: [Shouldn't this have been a gift from you? Why do I have to spend skill points? Even if I have a lot of skill points, I can't withstand this kind of exploitation, can I?]

System [Host, the final interpretation of this rests with the main system. I'm just an employee. You... will you buy it?]

Li Yao: "Buy, buy, buy! Give me a copy of the royal family genealogy and information too!"

System: [Okay, host. A total of 6500 skill points. Do you wish to confirm the purchase?]

Li Yao [Confirmed, hurry up, don't make me slap you]

System: [Okay, host. Purchase confirmed. Please click to use. The information will be directly entered into your consciousness.]

Li Yao clicked "Use," closed her eyes, and after a dozen seconds, just like learning a skill, she learned about the royal family background and the whole story of how the princess was switched.

It turns out that in the fifth year of the current emperor's reign, a locust plague occurred in the south. The empress, who was nine months pregnant, had to set an example by going to the Daxiangguo Temple to offer incense and pray for blessings in order to appease the people.

Finally, she was rushed into the temple and forced to give birth. But the baby was snatched away as soon as it was swaddled after birth. The royal guards gave chase, and by sheer coincidence, the thieves abandoned the infant on the mountain behind the village where the Zhao family lived.

Zhao Gou Dan went up the mountain to chop firewood and saw that the baby's swaddling clothes were made of rare silk. He thought the baby belonged to a wealthy family, and since his own family, Zhao Er Gou's family, had just had twins, he could use them.

Upon closer inspection, the baby in the swaddling clothes was still alive. Zhao Gou Dan, hoping to curry favor with a powerful figure and receive a reward if someone came looking for him later, took the child back with him.

After returning home, Zhao Ergou's wife breastfed the baby, and the child survived.

A few days later, people started searching the mountains, saying they were looking for an infant. Zhao Gou Dan and Zhang Cui Hua discussed it and decided to switch Zhao San Zhu's twin sister, who was also only a few days old, with the infant.

Since the children were all only a few days old, it was impossible to distinguish their appearances. They could only look for swaddling clothes. The guards who came to search knew that Zhao Gou Dan didn't have the guts to switch the royal princess, so they sent someone to write down the family's appearance and then took the children back to report.

Afterwards, Zhao Gou Dan lived in fear for a while. Seeing that the villagers and the village chief did not control them, he moved his whole family to their current location. The reward money at that time was basically used to purchase household registration and land here.

Li Yao asked the system, "Who is it that snatched the child?"

System: [Host, you are a spy from an enemy country, a Rouran.]

Li Yao: [Okay, I'll remember this. I thought it was a palace intrigue story, and we could go to the palace and wreak havoc. What a pity.]

System: [Host, try to read fewer novels with crazy female protagonists. What are you planning to do next?]

Li Yao: [First, create some auspicious omens for myself, then adjust my time zone to teach the Zhao family a lesson, and finally return to the capital to live the life of a spoiled brat.]

System: [Okay, the host does know how to grasp the key points, no problem.]
