After returning home and sleeping, Yusuke only took his morning class the next day, and in the afternoon, he went to the Wagashi shop, and the old lady told him that the katana had been found.

"Little master, this is it." The old lady handed over a katana.

Taking the knife, Yusuke looked at it carefully.

This is a knife with a curved blade, the pattern cast on the gauntlet is a piece of maple leaves, and the handle is wrapped around a silk rope that winds two diamond-shaped marks.

Pulling out the knife, Yusuke looked at the edge of the blade and was very satisfied.

"Little master, this is a first-class knife, and its name is Chiba Maru." The old lady and Yusuke introduced.

The grade of the knife is the same as the grade of the elixir, which is the lowest grade.

Although it is only a product, the knife of the first product is very rare, and it is enough to be used as a family heirloom in a small family.

Yusuke covered his aura on the blade and swung it twice, which was very easy.

The spiritual power cover is a skill obtained from "The Leaf Picker", although the "Leaf Picker" is not of high grade, but it also has unique features.

"This knife is the heirloom of the Sanzhi family, and it took a lot of effort for the old man to bring down this knife for the little master." The old lady narrowed her eyes and smiled even brighter.

"You can make an offer." Yusuke grabbed the scabbard and liked the knife very much.

"After all, it is a knife that has entered the grade, and the pill that the little young master took out before is a little ...... Low, right? ”

"What do you want?"

"It's not that the old body wants anything, but the Sanzhi family wants some pills that can improve their cultivation." The old lady said.

Yusuke glanced at her, took out a jade bottle from his pocket, and threw it away.

The old lady took it with a grin, and when she uncorked the bottle, her eyes narrowed into a slit.

"Pei Yuan Dan of Yipin, is it enough?" Yusuke asked.

"If you have ten bottles, that's enough." The old lady said.

Yusuke put five Peiyuan Dan in a jade bottle, which means that fifty pills are needed. In the case of ordinary exercises, fifty pills are enough to cover four years of penance, allowing a practitioner to ascend from the early stage of Qi cultivation to the late stage of Qi training.

Of course, there are bottlenecks from the early to the middle and the middle to the late stage, and the time cannot be counted in this way.

Yusuke frowned.

What made him hesitate was not the price, although he didn't know whether the price was suitable or not, but as long as the old lady still wanted to get the pill from him, he didn't dare to deceive himself.

What he hesitated was that he didn't have so much Pei Yuan Dan.

Half of the ones he had refined before had been eaten by him, and he hadn't refined them again these days, and now he only had four bottles and twenty Peiyuan Dan in his hands.

After thinking about it, Yusuke threw another jade bottle to the old lady: "What is the value of this elixir?" ”

The old lady took the jade bottle and stared at the pill inside for a while, a little puzzled. She took out an elixir, put it under her nose and sniffed it, scraped it off with her fingernails and tasted it a little more, revealing a shocked look.

"This elixir is rare?" Yusuke asked.

"Little master, don't make jokes about the old body, this is a first-class elixir, if the old man accepts it, the young master's parents will have to call the old body over to drink tea." With a sad face, the old lady handed the medicine bottle back to Yusuke.

Yusuke was surprised, he didn't expect this elixir to be so precious, and the old lady didn't dare to accept it.

The elixir is a kind of elixir that nourishes the soul, this elixir is mostly used when breaking through the bottleneck, after all, compressing the spiritual power in the body is a very soul-consuming thing, once there is a mistake, it will be seriously injured or dead.

This bottle of Divine Cultivation Pill was used by Yusuke for himself, and as a result, he broke through from the early stage of Qi training to the middle stage of Qi training, and it was a matter of course, and he did not encounter any obstacles at all.

That's why he thought that the bottleneck of the Qi refining period was too weak, and the first-grade Divine Pill could only be used in the Qi refining period, so the Divine Pill was also considered useless by him.

Now judging from the attitude of the old lady, it is not that the bottleneck of the Qi refining period is weak, but that her "Yin and Yang Jue" is clever and there is no bottleneck.

"How many Divine Cultivation Pills can be worth fifty Peiyuan Pills?" Yusuke turned the jade bottle in his hand, this bottle of elixir was of no use to him in the slightest, and it was already an unexpected joy to be able to exchange it for something.

"Little master, don't make jokes about the old body." The old lady waved her hand and refused to accept it.

"Don't worry, there won't be any problems with this bottle of Divine Cultivation Pill." Yusuke had to find a way to reassure the old lady.

"I have broken through to the middle stage of Qi cultivation, and I have not used the Divine Cultivation Pill, so it can be said that I have used it in the middle."

The old lady's complexion changed, she thought about the pros and cons, and in the end she still did not resist the temptation.

Three Divine Pills were taken out from the jade bottle, and the old lady's wrinkled face smiled brightly again.

"Is it hard to break through the bottleneck?" Yusuke asked.

"The young master's qualifications are outstanding, of course, there is no problem, but not everyone in this world has outstanding qualifications!" The old lady sighed and sighed.

Aptitude?

Yusuke touched his chin and felt as if he knew extremely important information.

He pretended to be unintentional and said, "Isn't qualification washable?" ”

"The elixir of washing qualifications is more valuable, and it's useless to wash it!" Putting the three pills in his hand into a jade box and putting them away, the old lady looked at Yusuke with more enthusiastic eyes than before.

She knew that Yusuke would be able to get something good.

Yusuke didn't notice the old lady's gaze, and he was stunned by one thing:

Does the world really need qualifications? Isn't it true that the Qi acceptance period of every exercise will wash the practitioner's qualifications to the most suitable point?

Wait, how did you come to this conclusion?

This conclusion was reached when he selected exercises in the previous life, and the exercises he chose seemed to be all ninth-order exercises......

Either way, it didn't hurt him.

After using a bottle of Pei Yuan Dan to exchange some medicinal materials from the old lady, Yusuke took a car to the small courtyard in the countryside and refined the pill.

In the evening, he returned home, ate dinner, washed up, picked up the ancient books he had exchanged from Sakura Tsukimi by the bedside, and entered the Inheritance Library.

After thinking about it, he felt that the Heritage Library was the safest place to put this unknown book.

Putting the ancient books on the shelves, Yusuke was just about to leave, but he saw the ancient books flying out of the shelves.

That's right, it flew out!

As if grasped by an invisible hand, the ancient book flew out of the shelves at the edge and into one of the shelves in the center of the library.

Coming to the bookshelf, Yusuke took out the ancient book in amazement, and he found that he was able to understand the words on the book, and this book was

- "The Nether"

Holding the book, Yusuke pondered whether he should try to enter black gas.

But the location of this book is the bookshelf of the eighth-order inheritance, and his own yin qi is definitely not enough to open the eighth-order inheritance.

But Yusuke tried it anyway.

He failed, and this inheritance cannot be separated from "Snow Moon Flower".

However, he also knew some information about this lineage, which was a practice lineage.

I didn't think that the exercises from the outside world could also be brought to the library, but unfortunately there was no reward for this kind of behavior.

Letting go of the matter, Yusuke returns to the present world, and he gets under the covers and prepares for sleep.

The night was silent, silent, lying on the bed with his eyes closed, as if he was in a mysterious space.

Ten seconds later, Yusuke opened his eyes.

Something is wrong!
