"Let's go our separate ways, this has a better chance, remember not to provoke others at will!" Zhi Yao instructed them with a serious expression.

"Yes!" the group nodded earnestly, then dispersed around.

Zhi Yao picked a random bookstore and walked in.

"This guest officer, what kind of books do you want to buy? Our store not only has basic enlightenment textbooks, but also has a lot of unique books from the previous dynasties. A guy greeted Zhiyao warmly.

"Just take a look. Zhi Yao shook her head.

"Okay, then you look slowly, what do you need to call me. The man walked away.

This service attitude is not bad, Zhi Yao nodded in her heart.

Half an hour later, Zhi Yao finished browsing the entire bookstore and had a certain understanding of the learning state of this world, but there was no trace of the secret key at all.

"Excuse me, have you heard of any keys?" Zhi Yao casually asked the guy without reporting hope.

"Hey, you're here to find the key?" a slightly questioning voice suddenly came from beside him.

Zhi Yao looked back and saw a scholar standing not far away with a few books in his hand.

When Liu Xi saw Zhi Yao turn around, she suddenly blushed, lowered her head and didn't dare to look at her, worried that she would surprise the beauty.

Seeing the other party lowering her head, Zhi Yao suddenly felt embarrassed, did she look scary?

"Hello, my name is Ye Zhiyao, do you know about the key?" asked Zhiyao with a smile as she tried to make herself as friendly as possible.

Liu Xi heard the voice, looked up, and instantly his entire neck turned red, and replied hesitantly: "Little ...... Xiaosheng Liu Xi is ...... It's a showman. What the girl ...... Said key small ...... Xiaosheng has one in his family. Only...... It's just that I don't know if it's what the girl is looking for. ”

"Then can you take me to see it?" Zhi Yao was overjoyed when she heard this.

"Yes, please come with Xiaosheng. After Liu Xi finished speaking, he staggered out.

Zhi Yao hurriedly followed, walked for about two quarters of an hour, and stopped in a small courtyard.

Liu Xi opened the door, welcomed Zhiyao in, and then invited her to the study.

"This is the key!" Liu Xi turned the vase, and a dark grid was displayed, and a key was inlaid in the center of the dark grid, with the word "Lingxu" written on it.

Sure enough, this was the case, Zhi Yao was overjoyed, and stepped forward to take it off, but found that she couldn't take it off no matter what.

"The elders of the family have told Xiaosheng that if someone comes to pick up this thing, he must be asked to copy the "Pure Heart Formula" before taking it away. After Liu Xi finished speaking, he prepared the pen, ink, paper and inkstone, and took out the "Pure Heart Formula".

Zhi Yao walked over, steadied herself, picked up the brush, lightly dipped it in a little ink, and began to transcribe according to the "Pure Heart Formula".

But as soon as she finished writing the first word, Zhi Yao's face turned red, and she looked at the dog-like words on the paper, she was really a little shameless.

Liu Xi was also a little confused, such a beautiful woman, how could this word be so ......

For the sake of the key, Zhi Yao could only write it down, constantly paralyzing herself, writing very well, very well.

But she was always panicked, after all, someone was watching next to her, and suddenly, Zhi Yao found that this "Pure Heart Formula" was actually a book of cultivating the mind, aiming to calm the mind.

Immediately, Zhi Yao silently recited in her heart, and soon the heat on her face subsided.

Slowly, Zhi Yao had forgotten where she was in the depths, and her soul seemed to have come to a paradise where birds and flowers were singing and flowing water, and the pressure on the whole person was relieved.
