The origin of this sword, in fact, can be traced back to ancient times, is a craftsman cast, but this craftsman has a strange temperament, everything he thinks is very understandable, to create this sword, no one can drive, because the world thinks that this is an impossible imperial method, in a rage, he sealed this sword with his own soul, since then, the craftsman and the spirit of the instrument are in harmony, self-sealed.

Today, he felt Duan Li'er's sword intent, and suddenly his heart was very happy, so he wanted to unseal himself, causing changes in the heavens and the earth at this moment, as if a catastrophe was coming.

A phantom shadow slowly appeared on the sword's body, making people not very clear, Duan Li'er glanced at the phantom, only to feel a roar in his mind, and a magic trick like a tide drilled into his mind.

Yue Mo took a cup of tea, Duan Li'er finished digesting the magic trick, a smile appeared on the corner of his mouth, and he nodded towards the phantom, at this moment, Duan Li'er inherited the mastery method set up by the magic craftsman for this sword, and at the same time understood the origin of this sword. Duan Li'er sincerely admired the spirit of this divine craftsman who sacrificed his life for the sword.

The phantom nodded, and he got into the sword very happily, the sword roared lightly, and suddenly the sword body changed, the original decoration suddenly turned into powder, and the sword body revealed a little starlight, like a star, which made people dazzled, but it was so clear, it made people feel very rhythmic, as if it contained the truth of heaven and earth, which was the formation on the sword body according to the distribution of heaven and earth stars in ancient times.

Duan Li'er stepped forward and shouted: "Yin and Yang double blades, only I command, crack." With a shout, the flying sword suddenly fell, and his body slowly shrank, turning into a three-inch size. I only heard a crisp cracking sound, from the top of the sword, cracking.

Suddenly, the two flying swords, one yin and one yang, flew in the air, and they collided and sparked dazzling sparks. There was a tremor in the stirring realm.

"One yin main attack, protect me, one yang main god, protect my god, god into the sword, ten thousand laws are one, together. When one of them heard the order, he let out a soft roar, happily turned into a ball of aura, rushed into Duan Li'er's mouth, followed the veins, and headed towards her Purple Mansion.

In the Purple Mansion, Duan Li'er's Yuan Shen throbbed, and happily rushed towards the aura that rushed in, and suddenly the sword body was displayed, and Duan Li'er's Yuan Shen was stored in the sword body since then, as if there was a protective film, if no one said that this sword was broken, then she would be eternal and immortal.

Feeling that the Yuan Shen was as light as if there were no restraints, Duan Li'er accepted this set of Yin and Yang Sword Spirit cultivation methods with great relief.

With a move towards the air, the half of the flying sword fell into the palm of his hand, and suddenly the wind and sun in the Xuan Realm were restored in an instant. The flying sword was like a naughty child in her hand, and she kept bending the tip of the sword and scratching her palm, which made Duan Li'er happy.

Looking at the flying sword that was only three inches in shock, the second elder was very surprised by Duan Li'er's blessings, but at the same time, he was also worried about her, since ancient times, people with deep fortunes naturally suffered a lot, and he couldn't help but pray for her in his heart.

"Li'er, let's give your flying sword a name. Bai Ziyu said with a smile.

Duan Li'er groaned slightly, and said: "This one in his hand is as soft and light as water, so let's call him soft, and the one in my purple mansion is strong and powerful, protecting my Yuan Shen and trying to protect me, so call him Zhenling." It seemed that she was very satisfied with her title, and there was a soft groan from Zifu and the palm of her hand, and with a turn of thought, Rouying turned into a ball of aura and drilled into her dantian, tempered by her danhuo day and night.

"Haha, Du Chengwu, now you can take it, my old man has such a thing in his hand, hehe, your old girl's ring is nothing. "Bai Ziyu has a rare opportunity to squeeze him, where would he let go of such a big opportunity?
