Fei Xing couldn't help but secretly said in his heart when he heard this: "It is rumored that this Tianmai Pill was originally found and refined by Zhang Laozu from the ancient books, this Lin Tianyang actually took out this pill, it seems that the master guesses that this person has an extremely close relationship with Zhang Laozu, it is really possible, it seems that this time I should indeed follow the instructions of the master and try to find out the foundation of this person."

Lin Tianyang didn't know that the reason why Fei Xing wanted to go to Yin Qiu Gorge with him was for another purpose, in his opinion, he just wanted some Xuanyin silkworms and used the Tianmai Pill to make a deal, which was enough, so he didn't take it to heart.

After chatting a few words, Fei Xing threw out a white jade battle boat and invited Lin Tianyang to enter together.

When he arrived at the battle boat, Fei Xing immediately drove the two god-transforming stage puppets to control the battle boat, and he sat in a quiet room with Lin Tianyang.

Because there was still some distance from Yin Qiu Gorge here, the two of them didn't need to be so anxious, and after chatting for a while, they exchanged cultivation experiences with each other.

Fei Xing is a disciple of the Mahayana Ancestor, with the guidance of the Mahayana Ancestor, and his understanding of various exercises and recipes is not shallow, Lin Tianyang has followed Chu Tianxiang, the Demon Ancestor of the Demon Realm, for a long time, and naturally it is not comparable to that of ordinary monks, and both of them have benefited a lot from the exchange.

Lin Tianyang didn't have anything, after Fei Xing communicated, he felt in his heart that with Lin Tianyang's views on some exercises, if he didn't have the guidance of a master, he didn't believe it himself, it seemed that the more he came into contact with this person, the higher the possibility of thinking that he was a disciple of Zhang Laozu and the like.

A month later, the warship finally arrived at the Yin Qiu Gorge.

Because the yin qi in this Yin Qiu Gorge is extremely heavy, people who have cultivated to almost enter it, almost have no return, so in order to place someone who strayed into it, ten thousand years ago, Shi Yanyan, the ancestor, used his great magic power to seal this place. Unless they have the strength of the Merge Period, they can't force their way in, and for the Merge Monks, the things inside are basically of little use to them, so few people come here to hunt for treasure.

Although Fei Xing did not have the cultivation of the merger period, as a disciple of Shi Yanyan, he had the magic weapon in his hand to open the seal gap, and although the yin qi in it was powerful, it was no longer a threat to cultivators like Lin Tianyang and Fei Xing. In fact, as long as you are a god cultivator, you can resist the yin qi inside.

After Fei Xing opened the seal gap, Lin Tianyang followed him inside.

Although few people come to this Yin Qiu Gorge, for Fei Xing, it is a place where he often comes. And the entire Yin Qiu Gorge is not too big, so after so many years. He knows everything about it, too.

The whole body of the Xuanyin silkworm is dark blue. The size is about the same as that of ordinary people after two fingers together, and generally has the strength of the god level after adulthood, and after spinning the silk cocoon, it will become an ancient demon butterfly like Xuanyin butterfly, but once the silk is extracted, it not only can't turn into a butterfly. And it will burst out and die immediately.

Because of Fei Xing's familiarity with this place, Lin Tianyang found a lot of Xuanyin silkworms within a few days after entering it, which made Lin Tianyang somewhat grateful to Fei Xing.

On this day, Lin Tianyang found a few Xuanyin silkworms. Fei Xing suddenly asked, "Lin Daoyou, have you found these Xuanyin silkworms, is it enough for your spirit treasure to refine?"

After Lin Tianyang listened, he calculated and said: "It should be too much, and it should be enough to find a few more for the sake of insurance!"

Hearing Lin Tianyang say this, Fei Xing smiled and said, "In this case, next, Fei Mou will go to one place to pick a spirit fruit that should have matured, and then take Daoyou to two other places where there may be Xuanyin silkworms?"

"Naturally, there is no problem with this, after Fei Daoyou and Lin came in, it took more time to find the Xuanyin silkworm for Lin along the way, Fei Daoyou should think more about himself!" Lin Tianyang said politely.

"In that case, let's go!" Fei Xing finished speaking, and immediately turned into a ray of light, and Lin Tianyang followed suit.

Less than two hours later, near a cold pool, Fei Xing's light fell, and Lin Tianyang landed next to him.

At this time, in the cold pool where the two of them looked, there was actually a small island that was only an acre in size, but on the so-called island, there were several small trees that were only half a person high, and each small tree had three or four black thumb fruits, adding up to almost sixteen or seventeen.

"Fei Daoyou, these seem to be bitter yin fruits!" Lin Tianyang looked at these black fruits, thought about them and said.

Fei Xing immediately nodded and said, "Lin Dao's friendly eyesight, this is indeed the Bitter Yin Fruit, and the Bitter Yin Pill refined with this fruit will be of great benefit to people like you and me who cultivate cold attribute exercises at the same level!"

After Fei Xing finished speaking, he flew directly to the island, but just when he was about to pick the bitter yin fruit, suddenly he shot into the air, and then a dark flying sword erupted from his mouth, and the flying sword went straight into the cold pool, and then suddenly a column of water rose into the sky, and in mid-air, it actually turned into the shape of a giant sword and stabbed towards Fei Xing.

Fei Xing was also shocked when he saw it, and hurriedly spewed out a piece of jade plaque from his mouth, as soon as this jade plaque appeared, it suddenly rose wildly, and with the flash of spiritual light, some runes were reflected, flowing uncertainly on its surface.

The pool of water that turned into a giant sword suddenly hit the jade plate, and it immediately cracked, turning into flowing water again and falling back into the pool.

Although he blocked this blow, Fei Xing's face became extremely ugly at this time, and he secretly said in his heart: "The last time I came, that cold python was far less powerful, how could it have become so strong in the past two or three hundred years!"

Just when he was a little puzzled, a whirlpool suddenly appeared in the cold pool below, this whirlpool became bigger and bigger with the continuous flow of the pool, and when almost the entire cold pool became a part of the whirlpool, a blue figure suddenly rose from the cold pool.

Fei Xing looked at this blue figure rising into the sky, a trace of horror appeared in his eyes, and he couldn't help but murmur in his mouth: "It's actually a cold ghost, damn it, that cold shadow python actually has a python as a dragon, no wonder its strength will increase so much!"

Lin Tianyang's divine sense swept over the dragon that suddenly appeared in front of him at this time, and he was also shocked in his heart, although this dragon was not a merger-level existence, but its aura was so powerful that it surpassed the ordinary continuous level of ancient beasts.

Suddenly encountering such a high-level dragon existence, Lin Tianyang didn't dare to sit idly by, and immediately flew into the air, and at the same time, twelve golden yang knives erupted from one mouth.

Fei Xing saw that Lin Tianyang did not choose to flee because this cold ghost was extremely powerful, and his heart was suddenly relieved, and at the same time he said: "Lin Daoyou, I only knew that there was a cold cloud python here, but I didn't expect this python to turn into a dragon, this Jiao's strength is far beyond you and me, we have to be careful to deal with it!"
