"The wisdom of the working people in ancient times should not be underestimated. You wouldn't be normal, but we saw just now that there were no springs on the carriage. They used some skins to make shock absorption." Sun Yingying quickly comforted, so as not to break Bai Yixiu's glass heart. "We can't ride in the carriage, but we can make simple springs. The iron and steel used in this is very special. If we do more experiments, we can finally find a suitable spring."

Hearing Sun Yingying's comfort, Bai Yixiu nodded, "Yingying is still you think clearly. I remember that there are many books in your space. If there is a suitable proportion, we will copy them directly to save us from working hard."

"Okay, OK." Sun Yingying nodded, "If you have time, then we will enter the space, but we must not let others know."

"Of course, that's a very secret matter." Bai Yixiu knew the importance of it. Some things can be said, and some things can't be said even if they are beaten to death. That space is his cave and the last secret between him and Sun Yingying.

"Oh, I almost forgot that Yuqi and the two of us disappeared together. Why don't I find the books inside and take them out first, and let's study them again. Is it different?" Sun Yingying quickly patted her head, feeling that she seemed to be being led by Bai Yixiu. She didn't expect such a simple method.

"Hahaha..." Bai Yixiu also laughed, "We two are like little fools."

"You are stupid, not me." Sun Yingying shook her head quickly, but she would not recognize such a nickname.

With things to do, it’s not so boring!

Sun Yingying found some books from the space. Fortunately, she bought a lot of books before, including chemical and physics. She is not professional, but Bai Yixiu should have the patience to read.

Bai Yixiu is really a little more patient than Sun Yingying, and he also likes to read these books more.

Madam Li personally brought the reward given to Sun Yingying by Crown Princess Yu Wanyi, and once again came to Prince An's Mansion.

With Caihe's help, Sun Yingying quickly changed into her clothes and came out to receive the reward.

As a folk girl, Sun Yingying always kowtows, but she can get a lot of good things every time, so she kneels down!

"Thank you for the reward of His Highness the Crown Princess, and also for the nanny who came here in person." Sun Yingying said with a smile, neither humble nor arrogant, and with appropriate advancement and retreat.

Madam Li smiled slightly, "Miss Sun takes action this time, and the Crown Princess is very grateful. If Miss Sun needs you in the capital in the future, the Crown Princess will definitely protect you."

"Thank you for your concern and love," Sun Yingying said with a smile. She did not doubt the words of Princess Yu Wanyi. She was a female doctor. The princess had to rely on her if she wanted to have a baby.

After showing goodwill, Madam Li began to get to the point and asked softly: "The Crown Princess has been taking the medicine for four days. Miss Sun, when is it suitable for entering the palace to take the Crown Princess' pulse?"

Sun Yingying thought for a while and replied: "That medicine will take seven days. I will go to the palace to take the pulse and change the medicine for His Highness the Princess."

Hearing this, Madam Li smiled, "Then the old slave will come to pick up Miss Sun in person."

"It doesn't take the nanny to work so hard. His Highness the Crown Princess needs a loyal person like the nanny to serve him." Sun Yingying refused. Just let Bai Yixiu take her into the palace at that time. There is no need to let Madam Li come here specifically.
