The princess traveled through time for a year to help the prince build his kingdom and then left

Qin Rubing returned to the dormitory, sent Zhuxiang out, and immediately summoned "Xiao Yu".

"Xiaoyu."

"I'm here."

"What kind of unknown secret does the queen have?" Qin Rubing frowned and asked in confusion.

"I do not know."

Don't know? This is not the answer that Xiaoyu would give, which is really surprising.

Qin Rubing pondered in her heart, could it be that this matter involves so many people that even "Xiao Yu" doesn't dare to reveal even a little bit?

Or is there something else hidden?

Thinking of this, she couldn't help but narrow her eyes slightly, as if thinking about something.

After a moment of silence, Qin Rubing decided to change her strategy and asked again: "Does Concubine Qi know some of the Queen's secrets?"

However, the response was still the familiar and doubtful words - "I don't know."

It's really surprising!

"Xiao Yu", who has always been well-behaved and diligent in her work, suddenly went on strike without any warning!

This is really incredible.

Qin Rubing was full of doubts, brows furrowed, and paced back and forth in the room, thinking hard about the reason.

She went over every detail related to "Xiao Yu" in her mind, but still couldn't find a reasonable explanation.

After careful consideration, Qin Rubing finally decided that it was necessary for her to go to the palace in person to find out the truth.

After all, "Xiao Yu's" sudden strike may hide some unknown secrets or troubles. If the situation is not clarified and resolved in time, it may lead to a series of unexpected consequences.

That night, she was both nervous and expectant, not knowing what the truth would be waiting for her...

The next day, Qin Rubing was thinking of a reason to enter the palace when the nanny beside the queen came to invite her.

She said that the Queen missed her.

Qin Rubing followed him to the Queen's Palace silently.

When the queen saw her, she was as kind and amiable as ever.

The queen had a smile in her eyes and a smile on her lips. She took Qin Rubing's hand and asked about her well-being.

"Rubing, you are my biological daughter-in-law. I like you just the way you look at me."

The queen gave her this and that to eat and was very enthusiastic.

Qin Rubing took them one by one with a smile and tasted them in small sips.

The queen pinched another piece of dessert and said, "Rubing, this sweet-scented osmanthus cake tastes great. Try it."

Qin Rubing waved her hands and said, "Mother, I'm full. I really can't eat any more."

During the scuffle, the armor on the Queen's hand accidentally scratched the back of Qin Rubing's hand, leaving a long cut.

"Oh!" the queen screamed, "Call the imperial physician."

Qin Rubing quickly covered the back of her hand, "Mother, it's okay, there's no need to bother the imperial physician."

The queen nodded slightly, asked the nanny to bring the ointment, and applied it to Qin Rubing herself.

The queen shed tears while applying medicine to Qin Rubing, "Rubing, I am really old and useless. I can't even take good care of you."

Qin Rubing was shocked. What was going on?

She was about to open her mouth to comfort him, but she heard the queen change the subject, "Rubing, don't blame me for being cruel, I had no choice!"

Qin Rubing immediately became alert, withdrew her hand, and asked, "What do you mean by this, mother? Your daughter-in-law doesn't understand."

The queen handed the ointment to the nanny and signaled her to leave.

There were only two of them left in the bedroom.

The Queen sighed and said slowly:

"Cheng'er is brave and resourceful, but he is too sentimental. How can he accomplish anything great? Xing'er is decisive and ruthless, so he is more suitable to be the crown prince."

Qin Rubing's eyes widened. "What? You want to support Chu Tianxing in his bid for the throne? This is impossible! Chu Tiancheng is your biological son, right?"

The queen sneered, "No matter who becomes the emperor, I will be the queen mother. But Xing'er is more suitable for that position than Cheng'er."

Qin Rubing was struck by lightning, her body swaying. She calmed down and asked, "Mother, why did you do this?"

The queen sighed again, "It's all your fault that you didn't want to marry Xing'er... If you want to live, just listen to me. Otherwise, don't blame me for not protecting you..."

As soon as the queen finished speaking, Qin Rubing felt dizzy.

Oops, I was careless. Could it be that the ointment is poisonous?

"Xiaoyu."

"I'm here."

"Antidote pills!"

"Yes, Master."

A pill instantly appeared in Qin Rubing's palm.
