Hearing this, Xue Ying hurriedly flew back to Lou Xiyan's shoulder, her wings shrugged down directly, and then silently retracted, as if the pair of wings did not exist.

"The Nine Shades and Five Poisonous Flowers are the companion flowers of the Black Snow Luo Butterfly, and generally speaking, there should be a Black Snow Luo Butterfly near the Nine Shades and Five Poisonous Flowers." Lou Xiyan explained, while carefully observing the Nine Shadows and Five Poisonous Flowers, while looking for the figure of Black Snow Luo Dad.

However, he didn't find the figure of the Black Snow Butterfly, and sure enough, as the book says, is the Black Snow Butterfly extinct?

"Lou Xiyan, what are you looking for?" Xue Hotaru asked curiously, and suddenly she accidentally caught a glimpse of a small chrysalis on the wall.

"Lou Xiyan, look at that!"

When Lou Xiyan heard this, he turned his head to look, and after seeing the black pupa of insects, his pupils couldn't help but shrink: "Black Snow Luo Butterfly?!" ”

"Black Snow Butterfly? Is it an elf bug? Xue Hotaru asked in surprise.

"Well, it's an extinct elven worm. At least, that's what the books say. "About a few decades ago, the black snow butterfly was not extinct, but it was nearly extinct, and the number was extremely rare.

When the black snow butterfly was a black snow worm, it mainly lived by gnawing on the leaves of the Nine Shades and Five Poisonous Flowers.

Black snow insects are particularly fragile and do not have any aggression, just like ants that can be slaughtered. If the surrounding environment is not humid and cold enough, the black snow insects will weaken until they die, becoming the nourishment of the Nine Shadows and Five Poisonous Flowers.

When it becomes a pupae, it is still very fragile, but it will no longer die due to changes in the environment, unless there are external factors that deliberately harm it.

After breaking out of the cocoon and becoming a butterfly, the Black Snow Butterfly was born, and the Black Snow Butterfly was very aggressive, living by sucking blood, whether it was the blood of elves or humans.

What's more, the Black Snow Butterfly generally possesses dark elements, and its appearance is very beautiful.

People also created a sentence to describe the black snow butterfly: "The silence of the night, the evil beauty of the night." ”

As a result, people went crazy to hunt the black sorrel butterfly, which led to its extinction.

In the Valley of Ten Thousand Dragons, very few humans have been able to successfully reach here, and even fewer have been able to get out alive.

Therefore, the existence of the Black Snow Luo Butterfly is reasonable, after all, this cave is cold and damp, which is just right for the Black Snow Luo Butterfly and the Nine Shades and Five Poisonous Flowers to survive.

"Ah, it's extinct......" Xue Hotaru couldn't help but think back to the elves who had witnessed being hunted by humans to the final extinction, and her eyes couldn't help but droop, revealing a faint sadness.

Lou Xiyan took out a dagger inlaid with seven elf stones and a dark black body from the space ring—the Night Thorn.

Although he didn't know what kind of material this dagger was made of, Lou Xiyan still had to try it.

After all, if an ordinary magic weapon cut off the Nine Shadows and Five Poisonous Flowers, it would be corroded by the poisonous juice flowing out of it.

So, with a flash of black light, the roots of the Nine Shades and Five Poisonous Flowers were quickly cut off by Lou Xiyan.

Seeing that the Night Thorn was intact, Lou Xiyan couldn't help but breathe a sigh of relief. Then he picked up the Nine Shades and Five Poisonous Flowers, and seeing this, Xue Ying was stunned: "Lou Xiyan, isn't it poisonous?" Then how dare you hold it in your hands? ”

"It's okay, cut off its roots and it won't be poisonous." Lou Xiyan explained as he put it into the wooden box he had just taken out, and then put it in the space ring.

"And what about this chrysalis?" Xue Ying pointed to the black insect chrysalis on the wall and said, according to what Lou Xiyan said, since the Nine Shades and Five Poisonous Flowers are its companion flowers, then without the Nine Shades and Five Poison Flowers, the Black Snow Luo Butterfly will not be able to live?
