Xu Bai was about to pay for it, but suddenly heard the bookstore owner asking, and looked at the bookstore owner with strange eyes.

"Are you sure you want this one, what's the problem?"

It's weird, do you have to decide in advance to buy a book?

It's not that kind of book, what else are you sure about?

Although he didn't read the title, he was sure that there were no illustrations on it when he looked through it casually.

That's normal!

"Alas, guest officer, you should pay attention to your body, you are young, you must know how to control yourself, I think I was ...... when I was young," the bookstore owner said as he sighed.

Xu Bai was stunned, subconsciously glanced at the book on the table, and then, the corner of his mouth twitched.

There are four words written in the book - the key to strengthening the kidney.

No wonder, no wonder you have to look at it this way......

Xu Bai took a deep breath and asked again, "How much?" ”

If you don't argue, the more you fight over some things, the more you can't explain them.

And no one knows him, even if he has a weak kidney, what's the matter?

"Thirty cents." The bookstore owner said.

"So expensive?" Xu Bai was stunned.

He finally knew why no one in the bookstore was buying books.

This money is enough to eat and drink several meals.

Buying a book? Dogs don't buy.

"It's all at this price, otherwise my bookstore wouldn't be unattended to buy books." The bookstore owner said worriedly.

Xu Bai didn't want to say more, handed over the money, picked up the book and was about to leave.

Before he could take two steps, he suddenly stopped again, turned his head and said, "Boss, how often do you enter the book here?" ”

"I'm here......" The bookstore owner thought for a while and said, "Once a month, the imperial court attaches great importance to reading, in addition to the first purchase, you can also replace it for free later, every month." ”

The Great Chu State is heavy on military force, and it is also heavy on literature.

The emperor paid special attention to education at the bottom, and even if it was a small county town, there were bookstores.

"Boss, next time you change all the books in this store, I'll come back next month, if there is anything I like, money is not a problem." Xu Bai walked up to the front and stuffed a piece of broken silver.

Since he can find something here that can stimulate his understanding, Xu Bai will certainly not let it go.

If you enter the book once a month, you can also replace it, then replace it all with a new one.

The bookstore owner was stunned for a moment, then silently put it away, smiled and nodded.

The two agreed on a time again, and when Xu Bai left, he was still standing at the door waving.

This year, for the first time, he was stuffed with money, and the bookstore owner was in a happy mood.

Xu Bai got the "Tips for Strengthening the Kidney", and he didn't have the heart to continue wandering, put the book in the package, and walked home.

Along the way, he was also thinking.

None of the other books triggered the comprehension progress bar, but "The Key to Strengthening the Kidney" was triggered, which means that other books have no trigger value.

Xu Bai thought about it, and there was only one result.

"Anyway, let's read this book first."

He didn't think much about it anymore and walked briskly towards home.

……

Bypassing the streets, Xu Bai finally stopped in front of the house on the west side of the county.

The house looks old, but it is a legacy left to him by the original uncle.

Digging around his waist, Xu Bai took out the key and opened the door.

"Squeak......

With the tooth-sour sound of the wooden door, Xu Bai pushed the door open, and there was no expected musty smell.

The room is clean and tidy, and the original person is also a person who loves cleanliness and cleans it often.

Xu Bai closed the door familiarly, found a chair to sit down, and couldn't wait to take out the book "Tips for Strengthening the Kidney".

Although the name is a little bit buried, it's good to trigger understanding.

He has a good kidney, just know it yourself.

Besides, it's okay to learn how to tonify the kidney.

Men, there is a good saying, people have to be middle-aged and soak wolfberries in a thermos cup.

Although Xu Bai is still young, the kidneys still need to be protected.

The eyes are fixed on "The Key to Strengthening the Kidney", and the progress bar is walking very slowly.

Compared to the prison cell, the progress bar is much slower.

Staring, Xu Bai felt bored.

"Or ...... Look? ”

He swore that he would never watch it because of kidney problems.

It's really boring, it's going to rise if you stare at it anyway, and it's going to rise if you read it carefully, so it's better to pass the time.

Thinking of this, Xu Bai flipped through the pages of the book.

At this glance, his eyes couldn't leave.

The speed of turning the pages was slow, and he read it carefully.

"It can still be like this."

"Huh? This action can strengthen the kidneys. ”

"Before going to bed, sleeping in this position can cure kidney yin deficiency?"

Xu Bai couldn't help but nod again and again while watching, and sighed from time to time.

He was really just curious.

It's vividly described, and at the same time it makes sense, and it's not at all as boring as other books.

When reading this book, Xu Bai still had an idea, it turned out that the kidneys really need to be well protected, and the handiwork should be done less.

Reading books is very time-consuming, especially when you are serious about reading books.

Xu Bai even forgot about the progress bar, and it wasn't until a line of text appeared in front of him that he realized that the progress bar was full.

[You have observed the key to strengthening the kidney and comprehended the method of beating the kidney. 】

Xu Bai was stunned, what is the hammer kidney method?

Before he could react, information came from his mind, and then the blue panel in front of Xu Bai's eyes changed.

[Name: Xu Bai.] 】

[Realm: Jiupin Wufu. 】

[Bone Breaking Knife Method (Level 1): Full level. 】

[Broken Bone Heart Method (Level 1): Full level. 】

[Kidney beating method (1st level): full level. 】

[Understanding: Full level.] 】

"It is also the first order, and the kidney beating method is longer than the broken bone series, and it seems that the first order is also divided into high and low." Xu Bai touched his chin and came to a conclusion.

He felt very excited.

It's like meeting a stunning beauty who is removing makeup.

With each unloading layer, the excitement is higher.

Explore the golden finger in just two words.

- Stimulation.

When the excitement gradually subsided, Xu Bai paid attention to his new abilities.

Kidney beating method, a very bad name, at least that's what Xu Bai thinks.

But sometimes, the reality is often even worse.

There is no other reason, the kidney beating method is really beating the kidney.

Xu Bai stretched out his hand, and the true qi in his body swirled, and then, in a way that ordinary people could not understand, he pounded at the position of his left kidney.

The true qi in the body has grown by one point, constantly rushing left and right.

"Being able to temporarily increase the content of true qi is equivalent to an explosion." Xu Bai withdrew his hand and said secretly.

After waiting for a stick of incense, the true qi in the body gradually disappeared.

And that's just the case of hammering one kidney, and if both sides are hammered together, it will be stronger.

Although the name is a bad one, the effect can completely replace the name.

"By the way, I remember that the negative effect is to weaken for half an hour."

He was too excited just now, Xu Bai tried it without thinking about it, and only then did he remember that this skill had a negative effect.

Xu Bai stood up, his steps vain.

walked to the table, picked up the bronze mirror on the table, looked at the pale face in the bronze mirror, and Xu Bai put it down silently.

"In short, don't use it lightly."

Half an hour of weakness is one thing, the main thing is that he doesn't want to really be considered kidney deficient.
