Hearing the middle-aged man's words, Yi Xing remembered his previous guess again, the books on the shelves outside and the books in the wooden box in Qingyi Mountain were all martial arts. Yi Xing was taken aback, there were more books than the books in the wooden box!

Yi Xing didn't know what this middle-aged man wanted to do when he collected these exercises, and it was obviously too much to ask a stranger about this. He said a few more exercises in the wooden box, and as expected, the middle-aged man said that he had a collection. Yi Xing has a headache, in addition to those martial arts, he has no treasures to exchange with others! "Ling Tian Sword Sutra" he will never exchange it, as his cultivation of the Sword Sutra continues to improve, he knows more and more that this Sword Sutra is extraordinary, not only because of this, he also promised the old man in Tsing Yi not to pass on the Sword Sutra easily.

Yi Xing didn't know that he had said many exercises and stunts of various sects, and the middle-aged man was also shocked in his heart. Originally, he heard that Yi Xing was going to exchange the sword with the "Heavenly Sword Technique", at that time he thought that Yi Xing was a disciple of the Heavenly Sword Sect, and he didn't know why as a disciple of the Heavenly Sword Sect, he easily passed on the sect's inheritance skills, but later Yi Xing almost told all the powerful sect exercises in the Heavenly Spirit Continent, and he was shocked that he didn't know what the identity of this young man was, and he knew so many skills.

Seeing that there were no treasures that could be exchanged for swords, Yi Xing prepared to leave.

When the middle-aged man saw that Yi Xing was leaving, he said: "Childe knows all kinds of exercises, and he is not an ordinary person. If there is no treasure today, he will have it tomorrow. It's okay to pick and choose!" He was very curious, and couldn't help but open his mouth to keep it.

Yi Xing didn't expect that there would be such a turnaround, there is no treasure exchange, and it is good to take a look.

The middle-aged man took out three oil lamps and asked the three of them to choose their own swords in the room.

There were a large number of weapons in the room, and the three of them separated and chose their own.

Yi Xing held the oil lamp in one hand, looked at the sword hanging on the wall, and stretched out his hand to remove the sword. The sword was very heavy to the hand, and Yi Xing put the oil lamp on the ground, held the scabbard with one hand, and the hilt with the other, and drew the sword. I saw that this sword was pitch black all over, and the material used to cast this sword seemed to be very unusual. Yi Xing tried the black sword and felt that the sword was very good, but he didn't have a comparison object, and he didn't know what was good, it was just a feeling. He put the sword back in its scabbard. The scabbards here are all about the same, and it should be that the middle-aged man remade the scabbards for each sword himself after getting these swords. I didn't notice that there were two words engraved on the scabbard: Black Oblivion, which should be the name of the sword. Black Oblivion Sword!Not bad name. Yi Xing rehung the black sword on the wall and looked at the other swords.

"Sancai sword!What kind of sword is this!" Yi Xing saw the words engraved on the scabbard. Reach out and take the long, large sword. When I got it in my hand, I realized that it was not a sword, but three swords put together in this big scabbard. He pulled out his sword, three thin and long swords! After separation, each sword was very ordinary, and when they were put together, they already felt that there was some hindrance in wielding the long sword, and it seemed that these three swords might be used in conjunction with what kind of swordsmanship, Yi Xing guessed in his heart.

One has a sword, and it is easy to pick it up and put it down. It's easy to look at and dazzling, each sword has something unusual about it, and each one is worth having. It's a pity that there are no treasures to exchange, otherwise any one is good, Yi Xing sighed in his heart.

"Brother, come here!" Su Su's crisp and sweet voice came. Yi Xing glanced at the swords in front of him with some reluctance, and turned around and walked towards Su Su.

"What's the situation?" Yi Xing asked as he came behind Su Su.

"Brother, look!" Su Su looked happy and handed the long sword in his hand to Yi Xing.

"Affectionate, what's the name!" Yi Xing was surprised by the strange name when he saw the name on the scabbard. Drawing the long sword, it turned out to be two swords.

"That's it, Su Su, don't you know it! There are three swords in a scabbard over there, and these are only two swords! There's nothing to make a fuss about, right?"

As soon as Su Su heard Yi Xing say this, his mouth suddenly pursed, and his mouth began to be broken: "Brother stupid, stupid brother! You don't feel the extraordinaryness of this sword, just say that, it's really a big fool, idiot......"

Yi Xing was broken by Su Su, and his head was a little dizzy. He had seen so many swords, and he also knew that the best way to understand the spirituality of the sword was to urge the true qi to enter the sword, and he could sense the spirituality of the sword, after all, when using the sword technique, he needed to urge the true qi to enter the sword.

Yi Xing was a little embarrassed when he saw Su Su's disgusted look. took a long sword that I don't know if it was called amorous or ruthless, and urged the true qi to enter the sword. True Qi entered the sword, and the long sword suddenly emitted a faint light, which looked extremely magical in this dark underground room. Yi Xing was pleasantly surprised to find that he seemed to have become one with this sword, this feeling had never been felt before when he had seen so many swords! This made him very happy, this sword is good!

Su Su saw Yi Xing's shocked expression, so he walked over and picked up another long sword that Yi Xing had placed on the shelf. said to Yi Xing: "Brother fool, next time I dare to say that I don't have knowledge! Hmph!"

"Huh, how can this be?" exclaimed Susu.

I saw that the two swords of Yi Xing and Su Su glowed faintly, as if there was an invisible suction, sucking the long swords in Yi Xing's and Su Su's hands together. Yi Xing and Su Su were holding a long sword alone, and the tips of the two long swords were pressed together.

"Ding......

The two long swords touched each other, making a crisp sound. Then the two were surprised to find that the long sword, which was still glowing faintly, disappeared after the sound. A strange texture appeared on the two originally smooth swords, like some kind of flower or plant, but they didn't recognize each other.

After hearing the sound here, Xu Gongzi and the middle-aged man came over.

Xu Gongzi is okay, he doesn't know what these two swords looked like before. The middle-aged man's face changed drastically. But he didn't say much.

"Senior, what's the matter with this sword? We didn't mean it, the sword made it ourselves!" Yi Xing asked the middle-aged man when he saw the change in the long sword.

"It's okay, these two swords are like this!" said the middle-aged man.

"Oh, then I'll be relieved!" Yi Xing let out a long sigh of relief when he said this.

"Qian Yichu didn't expect you old guy, you haven't died yet!" A shout came from the entrance of the underground room.
