"Then let it break out of its cocoon and become a butterfly there." Lou Xiyan looked at the black insect chrysalis on the wall and said.

"Are we going to leave it to fend for itself?" Xue Ying was surprised.

"Don't worry, after it breaks out of its cocoon and becomes a butterfly, it lives by sucking blood." Lou Xiyan explained.

Hearing this, Xue Ying couldn't help but be stunned, there were still elf insects that lived by sucking blood, and she thought it was strange enough for her to eat the carrion of various corpses.

"Well, let's go." Xue Ying said thoughtfully, since the Black Snow Luo Butterfly has become extinct in the Star Luo Continent, then at least the only remaining Black Snow Luo Butterfly in the Valley of Ten Thousand Dragons must be protected.

After exiting the cave, Lou Xiyan and Xue Ying entered another cave that was about the same size as the previous one.

As soon as Lou Xiyan entered the cave, he could feel the sound of heavy breathing, and there were some magic fluctuations.

Snow Firefly was even more apprehensive, shrinking itself into a ball, its blue fluffy tentacles hidden.

Lou Xiyan could barely see the giant creatures inside by the slight light outside.

He couldn't help but be stunned, it turned out to be the dragon clan he had encountered by chance when he and Snow Jade Dragon came to the Valley of Ten Thousand Dragons last time, the Yellow-level Wind Swift Dragon.

Lou Xiyan couldn't help but take a deep breath, it was a coincidence, it was sleeping last time, and this time it was still sleeping.

It seems that this is a lethargic wind dragon.

Sunlight from the outside spilled on one part of its body, refracting a faint blue light.

Although it is a relatively rare dragon family, it is famous for its speed, ranking second among wyverns in terms of speed, after the first-ranked Wind and Snow Pterodactyl, and the third place is the Purple Thunderbolt Dragon.

Judging from the speed of flight alone, the Storm Swift Dragon is actually faster than the Wind and Snow Pterodactyl. However, the Wind and Snow Pterodactyl possesses a top-secret magic comparable to a flash.

In fact, it is simply so fast that it cannot be seen by the naked eye, so it looks like a flash in the eyes of ordinary dragons.

The so-called top-secret magic is a powerful and mysterious magic created by the elves from generation to generation, and this magic can only be learned by the elves of the same race. However, only a small number of elves are able to learn it successfully.

Top secret magic is not available in every elf, except for the elves.

Lou Xiyan silently took out the Night Thorn from the space ring, he held the Night Thorn tightly with his backhand, put it behind his back, and then quietly approached the Wind Swift Dragon.

Xue Ying was so frightened that she hurriedly buried her head in the fluff and didn't dare to look at it again.

Although Lou Xiyan's face was indifferent, he was still a little nervous in his heart.

However, at this moment, the Swift Wind suddenly rolled over and slept in a different direction.

Xue Ying suddenly trembled with fright, and Lou Xiyan froze in place.

After a while, after seeing that the Swift Wind Swift Dragon was breathing steadily, Lou Xiyan adjusted his mentality and continued to approach it.

Lou Xiyan raised the Night Thorn, stared at one of the blue dragon lins tightly, and then raised the knife in his hand and cut off a piece of dragon lin with lightning speed.

Seeing the blue dragon lin in the palm of his first hand, Lou Xiyan couldn't help but breathe a sigh of relief.

However, at this moment, he suddenly felt a sense of fear coming from his bones, he slowly raised his eyes, and a pair of blue vertical pupils suddenly broke into his eyes.

"Lou Xiyan...... Yes! As soon as Xue Ying showed her head, she was greeted by a pair of big blue dragon eyes, and she suddenly screamed in fright.

Lou Xiyan's whole body froze in place, and the sense of fear dominated him, and he couldn't move and escape.
