This jade is transparent, like crystal, but it emits a faint light, each piece as big as the palm of the palm.

"As long as you put the content of martial arts into it, the martial arts will be automatically imprinted inside it." The middle-aged man in gray explained.

"Okay." Ye Xiaofeng nodded, stretched out his hand, and a jade appeared in his hand. An invisible energy was input into it, and the two breaths were completed.

There was a trace of light flowing in the jade block that had been imprinted with martial arts, and the trajectory looked mysterious.

Ye Xiaofeng put the jade block with good martial arts on his other half, and then took another jade block.

When Ye Xiaofeng was marking his martial arts skills, the middle-aged man in gray took a piece of jade that marked his martial arts skills and checked it, with a look of satisfaction in his eyes.

Not long after, all seventy top martial arts and one hundred and eighty slightly weaker martial arts were branded.

"Can you give me the remaining jade?" After the branding, Ye Xiaofeng took a deep breath and asked.

"You are really a man who will not suffer any losses." The middle-aged man in gray smiled, "Okay! I'll give it to you."

Ye Xiaofeng took away the jade without any politeness. He had never seen such jade before, let alone possessing it. Don't want it for nothing.

"I have given you all my martial arts now. It won't take long to practice the system software to send it to you. I wonder when I can enter the library of your Ouyang family to view it?" Ye Xiaofeng asked.

"The transaction is fair. Although those instruments have not arrived yet, I believe in your character. You can go in at any time. Do you want to go in now?" asked the middle-aged man in gray.

"Yeah, now." Ye Xiaofeng nodded.

"Fengjiang, take Mr. Ye Xiaofeng to the library." The middle-aged man in gray said.

"Yes." Ouyang Fengjiang outside the hall said respectfully.

Ye Xiaofeng nodded slightly, then walked out with Ouyang Yuqian.

After the two left for a long time, the middle-aged man in gray showed a smile on his face, "With these martial arts and those instruments, the strength of our Ouyang family can be enhanced again."

"Brother, should we send someone to stare at them?" asked the middle-aged man in purple.

"This is not necessary. They must be trying to find clues about those things from the library of our Ouyang family. I have to say that they are quite smart. The martial arts and skills accumulated in our Ouyang family may not be as good as other families, but other types of books must be the most complete." said the middle-aged man in gray.

"Brother, I don't know what the use of those three things they want. We have never heard of those things." The middle-aged man in purple asked in confusion.

"Maybe it existed in the age of the gods!" said the middle-aged man in gray with some uncertainty.

"With his age and experience, I definitely don't know these things. I think it's very likely that the Moon God told him that the Moon God's cultivation has already reached the peak of the holy realm. You said that it would be using those things to restore his cultivation!" The middle-aged man in purple speculated.

After hearing this, the middle-aged man in gray was silent for a moment and fell into thinking, "We don't pay attention to the library. There are people watching over there, but after they leave, they must keep an eye on it. They must find out what the three things are useful as soon as possible. If they can really help people break through, we may also look for them."

"Okay, brother." The middle-aged man in purple answered.

Speaking of which, after Ye Xiaofeng and Ouyang Yuqian came to the library, they carefully searched for books about martial arts. They skipped the books on martial arts and directly looked for books such as notes and things.

When Ye Xiaofeng was looking for clues to the three mysterious things, two scientific and technological personnel from Shenfeng Technology and five masters came to the Ouyang family to install those things for their family.

In the past few days, some teams sent by the Longteng Alliance have killed many Lingmu clan powerhouses in those countries south of China and seized many leaves at the hearts of many Lingmu clan masters. These leaves can be used to refine pharmaceutical liquids.

If Ye Xiaofeng knew that the leaves could still be refined with pharmaceutical liquid, he would definitely regret it. At that time, Indonesia had no idea how many Lingmu clan masters had been killed, but all the leaves in the hearts of those masters were destroyed by him.

The 108 Gods of Thunder God worshipped the Divine Cult, and the power of the 108 Gods Generals were boundless. They were in the north of M Country, making the Divine Feather Clan dare not invade. As for the Demon Spirit Clan, they also entered the rest stage, but many teams were sent to harass them.

As a whole, only the demon spirit race captured more land, and only the black demon race was the worst. They paid a great price, but did not enter China. In the end, they had to change their strategies and attack other countries first.

At present, the Blood Shadow Clan and the Black Demon Clan are still attacking human land, and other races have basically suspended. After all, they have to digest it, otherwise they will occupy too much land and the front line will be stretched very long, which is not conducive to management.

In the Ouyang family's library, Ye Xiaofeng and Ouyang Yuqian searched for seven days, but found nothing, which made Ye Xiaofeng feel disheartened. Fortunately, there were still some books that had not been read.

If there is no clue in the Ouyang family’s library, I’m afraid there is really no information about those three mysterious things in the world.

Another day passed, Ye Xiaofeng had searched all the books on the shelves he had checked at this time, and a look of fatigue appeared on his face.

At this time, Ouyang Yuqian was still flipping through the book, and his eyes were flashing.

After eight consecutive days of searching, Ye Xiaofeng's spirit was consumed a lot. He rested quietly for a while, and when he felt that he had recovered almost, he began to search.

Two days later, they had already searched all the books in the Ouyang family's library, and the two met in front of the last row of bookshelf.

"How is it?" Ye Xiaofeng asked, rubbing the position between his eyebrows.

"I didn't find any clues, but I found several special places. What about you?" Ouyang Yuqian asked.

"I'm the same, let's go! Let's study it after we go back." Ye Xiaofeng said.

"Yeah." Ouyang Yuqian nodded.

The two of them had just walked out of the library and walked forward for a distance when they saw a middle-aged man in gray coming over. Five or six people were following him, all of whom were masters of the eighth level of the Holy Realm.

"You two have finished reading the collection of our Ouyang family?" asked the middle-aged man in gray with a smile on his face.

"I've finished reading it, thank you."

"How is it? Have you found what you want?" The middle-aged man in gray narrowed his eyes slightly and looked at Ye Xiaofeng seriously.

Ye Xiaofeng sighed slightly, "It's not that easy. It's too rare to find what happened a long time ago. I can only infer from some details."

"We have been disturbing the Ouyang family for many days and left."

"It's okay, you are distinguished guests of our Ouyang family. You can stay as long as you want." The middle-aged man in gray said with a smile.

"We also want to stay for a while, but there are too many things in the league, so we have to leave."

After saying something to the middle-aged man in gray, Ye Xiaofeng and Ouyang Yuqian left the Ouyang family.
Chapter completed!
