Yesterday, he also tried to use gray qi to improve the proficiency of the Yin and Yang Technique, but he didn't get any other improvement except that he felt that he was more proficient in the cultivation of the Running Technique.

The Dharma is the foundation of cultivation, just like walking, the rough level will not be crooked, up and down, even if the walking skill is improved, it will not have much effect.

Of course, if you add up to a lot of trick proficiency, the benefits from increasing your skill proficiency are also considerable, but since there are other methods that can bring benefits in a short period of time, why not use them up first?

What Yusuke needs to deal with now is the young masters of the upcoming cultivation world, and he can't quench his thirst from far away.

Having made up his mind, Yusuke put the gray gas bead in front of "Snow Moon Flower", and the condensed gray gas bead quickly dissipated, and the scattered gray gas poured into "Snow Moon Flower", and after the gray gas bead completely dissipated into gray gas, leaving only a thin gray gas the size of a basketball, he stopped the delivery of gray gas.

Almost all the gray qi was entered into the flower chapter in "Snow Moon Flower", but the proficiency of the flower chapter was only half reached.

All kinds of swordsmanship were practiced freely in Yusuke's mind, and in his vision, it was not swordsmanship, but flowers in full bloom.

After another hour, Yusuke put down the book and breathed a sigh of relief.

His eyes were fixed on the ash in his hand, and there was not much ash left.

For the same inheritance, the investment of gray gas is much more than that of black gas.

In order to prevent anything from happening, he had some discouragement left.

Glancing at the monster trembling on the ground, Yusuke walked out of the Heritage Library.

Arriving at the small courtyard of the house, Yusuke took out the katana given by the Kurai family, he held the knife in his right hand and the sheath in his left, the tip of the knife hung on the ground, and stood in front of a potted plant in the corner of the wall.

Just standing so leisurely, a sense of elegance and idleness appeared on his body.

Three seconds later, he tucked the katana into its sheath, and the feeling of elegance and indifference in his body vanished.

After he left, the plants in the potted plant snapped into two.

The name of this style is plum, the fragrance of plum blossoms is light and elegant, and it was called dark incense by the ancients, and this style is a dark sword that matches the fragrance of plum blossoms, elegant and hidden.

When you're playing against someone else, it's a killer move.

Returning the katana back to the Inheritance Library and looking at the small courtyard, Yusuke felt a little regretful.

The swordsmanship that can be used now from the flower chapter has a total of three styles, one is desperate swordsmanship, and the other is frontal attack swordsmanship.

The desperate swordsmanship hurts the body and can't be used at will, and the swordsmanship that attacks head-on can't be used because there is nothing to bear.

However, these three styles are already extremely strong swordsmanship, and with these three styles of swordsmanship, he is confident that he can easily defeat Hanazawa May.

Back in his bedroom, he entered the Heritage Library again, and the matter of the Black Shadow Yin Spirit still needed to be resolved.

Arriving at the library, Yusuke glanced at the ground and found a black figure the size of a watermelon hiding in the corner.

He came to the shadow.

"What do you want to do!" There was some weakness in the dark shadow's tone.

"I think we can talk about it now," Yusuke said.

"I don't have anything to talk to you about! Give me my body back! ”

"Looks like you haven't realized your situation yet!" Yusuke took a copy of the inheritance from the bookshelf and shook it in front of the monster.

Seeing the inheritance book, the black shadow remembered the way his body was absorbed by the book, and he couldn't help but be afraid.

"What the hell do you want!" It asked. This means that it has given in to Yusuke.

"I just wanted to ask you a few questions." Yusuke sat down in front of the dark shadow and placed the inheritance book in the middle as a demonstration of deterrence.

"What are you?"

"Yin Spirit."

"Why is it sealed in an ancient book?"

"I was attacked by a powerful being, I was going to win, but I didn't expect him to see that he couldn't do it, and he spent his life dragging me into the water and sealing it."

"Who is that being?"

"I don't know, I'm confused, and they attack me for no reason!"

"Do you know about sealing your ancient book?"

"I don't know."

……

Yusuke asked some more about the Yin Spirit, and other information was basically useless except that he learned that the other party came out of the Netherworld.

"Where is the netherworld, how do you get in?" Although Hanazawa May promised to take him to the netherworld, Yusuke is not someone who likes to follow behind others.

"I was born in the Netherworld, and I don't know where it is."

"And how did you get here?"

"I was patrolling the territory that day, and suddenly a hole opened in front of me, and then that guy came out of it, attacked me, and sealed me desperately, and then I don't know how I came here, probably that guy did it!"

"How much strength can you rank in the Yin Spirit?"

"None of the Yin Spirits I have encountered are my opponents, and I don't know what I have not encountered."

Touching his chin, Yusuke came to the conclusion that the Yin spirits in the Netherworld might not communicate much.

"The last question, how much do you know about that gray gas?"

"Gray gas? What ash gas? ”

"Seal your ashes." Yusuke stretched out his hand and showed the dark shadow the gray yin qi.

"No, it's a nasty force that seals me, not this!" The Shadow denied it very decisively.

Yusuke frowned, he also thought that the gray yin qi came from the existence of the attacking black shadow.

"Is there any danger in that ancient book?" Yusuke asked again.

"Isn't that the last question just now......" Under Yusuke's gaze, the voice of the black shadow became smaller and smaller, and it replied resignedly, "There is no danger, I have been walking in there for more than a month, and I haven't seen anything." ”

It added: "That guy was going to seal me in another thing, but that thing was destroyed by me who noticed it, and he took out the book." ”

Yusuke's question about the ancient book is for Sakura in the moon, although the ancient book is not normal, but the girl likes it very much, and if she takes it by herself, the girl will definitely lose her temper.

And logically speaking, in the case that the ancient book has no owner, the girl who got the ancient book is already the owner of the ancient book.

If there's no danger inside, stay with the girl.

After thinking about it, Yusuke felt that this was still a little inappropriate, and looking at various fantasy works, many of them were caused by picking up something strange.

Although this is a reality, it is better to recycle the old books just in case.

Let the Kurai family take a few ancient books for themselves, and then exchange them with the girl.

The next moment he decided on this, Yusuke took action, and he left the Inheritance Library to send a message to Kurai Shunji.

After swiping the screensaver on his phone, Yusuke finds an unread email from Kinji Muto and asks him to come over when he is free.

Yusuke replied tomorrow afternoon.
