This palace is from modern day 2

Chapter 201
The implication is that it is a bit like Nangongchen kidnapped Princess Fengqingguo.

Nangong Chen frowned unhappily, and said to the female envoy, "I don't know any of your princesses at all, how can I pay back?" In his life, there are only a handful of women who appear.

"His Royal Highness once wrote a letter to my servants. Two years ago, she sold her body here. The buyer happened to be the empress of your country. Her Royal Highness asked us to redeem her body after two years."

After the maid finished speaking, Nangong Chen's complexion suddenly changed, and then he narrowed his eyes, "Does the princess you mentioned look like a boy?"
The maid was upset when she heard this, and explained, "Our princess is handsome and beautiful, and she is one of the best in Fengqing Kingdom."

...That's not the point, is it?!
"About ten years old, kung fu is quite good, there are two small dimples at the corner of the mouth?"

The little boy who stood behind Yanran and protected her must be the princess of Fengqing Kingdom, right?
The maid nodded, "The princess does have two dimples."

Is it really her...

Nan Gongchen leaned his back on his back a little dejectedly, "I am also looking for them now, they have been missing for two years."

The maid opened her mouth wide and looked at him in disbelief, "What? But, the time agreed by the princess has come..."

Nan Gongchen asked the envoy Feng Qing to stay, and then walked to the Queen's Palace by himself.

Nangong Ye was teasing his little princess happily, when she saw Nangong Chen coming again, she just glanced indifferently, as he continued to play with her daughter transparently.

But Gu Yiyi couldn't see it, seeing Nangong Chen's preoccupied appearance, Guan asked, "What's the matter, Chen'er?"

Nangong Chen looked up at Nangongye, then at Gu Yiyi, "Mother, do you still remember that I mentioned to you, of course, the little boy beside Yanran?"

Gu Yiyi nodded, "What's wrong?"

"She turned out to be the princess of Fengqing Kingdom."

Nangongye continued to develop a relationship with his daughter without any surprises. Looking at Nangongchen was jealous. When he was a child, he never saw his father treat him like this.

"What?" Gu Yiyi was surprised, "Princess?"
