Xiao Ziyi's face suddenly changed, and an extremely depressed and cold breath came to his face. He felt a special feeling of fear for no reason in his heart.

Yang Xuan is quite different. He feels an unprecedented sense of intimacy. This feeling is like an old friend who has known him for many years calling himself.

A black knife about a foot and a half long, as thin as a cicada's wing, is dark all over, but you can see some dark red and blood lines in front of you.

Yang Xuan carefully stretched out his hand. As soon as he touched the handle, the blade suddenly began to tremble and make a buzzing sound.

Yang Xuan's heart pounded, and a feeling of Indescribability surged into his heart. When holding the black knife, he seemed to feel that the black knife was like an arm and leg, which was originally a part of his body!

Drink——

This feeling made Yang Xuan very excited. He couldn't help shouting, then his body flashed, Shua and slashed a knife in the air.

Boom!

With this knife, a crack about one meter wide and more than ten meters long suddenly appeared on the ground!

"Good knife, I found it, I found it!"

Yang Xuan couldn't control his excitement. When he held the knife, he felt that his combat effectiveness had improved more than one grade in an instant!

In fact, when Yang Xuangang graduated from the training camp of the owl group, his combat effectiveness had reached its peak.

But Yang Xuan always felt that he was missing something, like something blocked in his blood vessel.

Over the years after graduation, no matter how Yang Xuan practiced, his combat effectiveness was stagnant. He always felt bound by an invisible force.

Yang Xuan racked his brains and couldn't figure out what the reason was.

Until now, this mystery has finally been solved!

What he lacks is the black knife. When he holds the handle of the black knife, he feels that every pore and every meridians all over his body suddenly connect!

This feeling is very happy. Every cell of the whole body seems to be injected with a pure breath. The body seems to contain inexhaustible power!

"Purple, I found it, I finally found it!"

Yang Xuan looked at Xiao Ziyi gratefully. If she hadn't insisted on bringing herself here, I'm afraid she wouldn't have seen this black knife in her life.

"Congratulations, but this knife is so fierce that I almost fainted just now."

Xiao Ziyi stretched out her hand and gently wiped it on her forehead. With a happy smile on her mouth, she looked at the black knife and said with a smile, "I'm afraid only you can control the hostility of the knife in this world."

"Of course, I am the real owner of this knife!"

As Yang Xuan spoke, he was so excited that he gently stroked the blade as thin as cicada wings and saw two strange symbols engraved on the handle.

"Do you know what this is?"

Yang Xuan asked the erudite Xiao Ziyi for advice.

After staring at the two words for a while, Xiao Ziyi said, "this is an ancient inscription. These two words are translated as Tiance."

"Tiance? Xuantiance?"

Yang Xuan was stunned and then said in some surprise, "it seems that the rumor in the town is true. Not only does he really have xuantiance, but he does leave the ancestor of ten thousand soldiers. It's amazing!"

Xiao Ziyi said with a smile, "there are all kinds of wonders in the world. Those strange legends are not groundless, but many people think they are right and don't want to admit it."

"Since the name of the elder xuantiance is engraved on the blade, this Dao will be called Tiance Dao in the future!"

Yang Xuan nodded hard, "Tiance Dao, good name!"

"This should be a knife manual!"

Yang Xuan set his eyes on the Yellow thread bound ancient book in the flat box. He went over and turned it over with his hand. He was surprised to find that there was no word in it. Page by page were all blank yellow paper!

"No, when the box was opened just now, I clearly saw the words on it."

Xiao Ziyi also looked puzzled. The moment the box was opened just now, the ancient books in it were automatically read.

Xiao Ziyi clearly saw that there were words on it at that time, but why did it suddenly disappear in the blink of an eye?

They tried many ways, looking through the sun, soaking in water and baking over fire, but the paper still didn't respond at all.

"It's strange. Just give me a knife instead of a knife spectrum. It's useless."

Yang Xuan looked regretful. It was like giving an atomic bomb, but he didn't know how to detonate it.

"You have to go back and study it yourself."

Xiao Ziyi said, "since master xuantiance left the box and the knife together, it shows that there must be an inseparable relationship between them."

"Maybe you can solve this secret by chance."

"By the way, there's another thing. Although I don't know martial arts, I've also seen a lot of classics in this regard."

"This Dao is definitely the highest spiritual weapon. It already has an independent soul. It can cut iron like mud, and it can be soft. These concepts are just the most basic for this Dao."

"A weapon with an independent soul will be integrated with its owner, and its combat effectiveness will naturally be immeasurable."

"But such a spiritual weapon also has disadvantages, because it has an independent soul. It's like two people. They can't come together until they have the same personality."

"Otherwise, if you can't control it, it can only be regarded as the best result. Maybe you will be eaten by the spirit product."

"When this knife appeared just now, I felt an unimaginable hostility."

"This shows that the soul of this knife is extremely ferocious and violent. You must be careful when using it. If you don't control it well, I'm afraid there will be big trouble."

Xiao Ziyi's head really contains thousands of knowledge, as if she could tell everything she could see in the world.

"Ha ha, that's just what I want. There's a saying that villains need to be sharpened by villains. I'm a great villain myself. I'll see if it's me or this knife. Ha ha ha!"

Yang Xuan didn't take what Xiao Ziyi just said seriously. Although he was also a well-informed man, he always felt that what Xiao Ziyi just said was too outrageous.

No matter how powerful this knife is, it is always just a weapon. Just like the atomic bomb, no matter how fierce it is, it still needs someone to control it?

But at this time, Yang Xuan would never dream that the seemingly outrageous words just said by Xiao Ziyi were the truth of every word!

"Ziyi, why don't you go back to Nanjiang with me for two days?"

When he passed the security check at the airport, Yang Xuan suddenly felt a little reluctant.

Xiao Ziyi smiled, "OK, I have no problem, but after I go to Nanjiang, will I sleep with you or with my sister?"

"Well..."

Yang Xuan scratched his head in embarrassment. If Su Nan knew he had a concubine outside, he had to pull out a layer of skin.

After returning to Nanjiang, what Yang Xuan did most every day was to hold the blank ancient books for various studies.

But half a month later, there was still no clue.

What exactly does elder xuantiance want to express?

Yang Xuan thought hard. Suddenly, a group of people came to mind!

Sumo!

Those ancient people who live in seclusion in the mountains with the Longyin nationality always boast that they are the descendants of the divine sword transformed by Pangu's divine axe. Maybe some of them can understand the mystery of this ancient book!
