[Rainbow Slime], a seven-color body that glows slightly at night, like a neon second-order slime.

It is characterized by its ability to spit out seven-colored rainbows on rainy days, and is often used to decorate the façade of some large cities.

But its properties are just ordinary!

It can't spray water or spit fire, and when many people first see the "Rainbow Slime", they often think that it has seven attributes because of its body color, but that's just a misconception.

The color of the Rainbow Slime is like a peacock's tail, but it is just a tool used for courtship.

- [Rainbow Slime] is a rare slime with male and female gender in the large group of slimes!

Rowan will notice such a slime that has no advantages other than ornamentality, at first because of its male and female characteristics, and later in deep digging, he discovers a conjecture about the [Rainbow Slime].

The author of that conjecture is a scholar specializing in the reproduction of monsters, and his name has been forgotten in the long course of history, but his nickname has survived to this day.

Compassion and compassion, popular and grassy.

Because of this, people call it "sad wind".

Sadness is a true scholar, in order to study the way of monster reproduction, he did not hesitate to go to the sea to practice, and spent decades to forge a long book, called "The Origin of Monsters", which provides a huge and real data for human beings to study the habits and weaknesses of monsters.

Unfortunately, after completing "Monster Origin", he died of overwork, and some people slandered his death because he had AIDS.

Monster Origins is one of the few books that also studies slimes' habits, and Rowan borrowed it from the library and still sits on the shelves in the lab.

In the book, Grief writes: "The Rainbow Slime is the most beautiful slime I have ever seen, and its beauty is not only shown in the appearance of the seven colors, but also from its inside. It wasn't until I came into close contact with it that I discovered the special structure in its body, which resembled a magnificent spiral corridor, and I even suspected that the Prissym Slime was the ancestor of all slimes, not the now-recognized original slime. ”

[Primal Slime] is often considered to be the ancestor of slimes, which comes from a popular concept of "evolving from weak to strong", and [Primal Slime] is obviously the weakest of the entire slime group, and it does not have superfluous attributes, so it has the potential to evolve to various attribute branches.

However, in the sad wind's remarks, the [Rainbow Slime] is the ancestor of the slime race, and it is the reproduction between [Rainbow Slimes] that low-level slimes with various attributes are born, and then these low-level slimes form a huge group of slimes through evolution.

Rowan is very interested in this kind of statement, and if Sadwind's conjecture is correct, he will most likely make the [Firedemon Slime] go in the direction of the [Rainbow Slime].

Until then, it would be necessary for him to take a look at the Rainbow Slime for himself.

From the standpoint of a researcher, he has an absolute advantage that the Sadness Wind does not possess - he can verify the correctness of the Sadness Wind conjecture through in-depth analysis.

……

Yanyun Mountain, near Jingnan Town, is notoriously beautiful and spectacular in the entire province of Changqing.

In particular, the three important places of Lingfeng, Lingyan and Dalongyu are called "three unique clouds of smoke and clouds".

Of course, this kind of artistic conception of playing in the mountains and rivers is only qualified to be enjoyed by strong people who can ignore the monsters around them.

Luo Wen is not yet a strong man, so he and Wang Yan both raised their vigilance to the limit when they rushed to Yanyun Mountain, and did not have the leisure to watch the smoke-filled and magnificent Yanyun Waterfall!

On the way, Rowan revealed a little bit of his research on the slime mutation, because he had his own pet as evidence, Wang Yan didn't doubt it at all, and looked at Rowan like a star chaser staring at a star.

Luo Wen thought that he could finally gain some admiration from this childhood sweetheart.

Unexpectedly, Wang Yan patted him on the shoulder, and said in an old-fashioned manner: "Study hard, and when you have research results, don't forget to honor your sister." My Bright Butterfly can't wait to evolve! ”

Variations with uncertain direction and uncertain probability are called "variations".

But a mutation with a definite direction and a 100% chance is no longer mutation, but "evolution"!

Wang Yan was obviously eyeing him.

For this reason, Luo Wen shook his head helplessly, Wang Yan's Bright Butterfly was already the third order, and the third order to the fourth order was a qualitative process, how could it be so easy to study.

……

Stepping into the Smoke Cloud Mountain, crossing the slightly bizarre mountain path, and carefully avoiding the monsters that forage at night, Rowan and Wang Yan gradually approached the Great Dragon Stream.

In an instant, thousands of horses galloped, thunder shook the sky, and its shape was not seen, but its sound was heard.

The Great Dragon Stream of Yanyun Mountain is a large waterfall that rushes endlessly.

From a little distance, the big dragon is like an angry silver dragon, swooping down from mid-air, the sound is like thunder, shaking the sky and the earth, the momentum is magnificent, it is worthy of being a wonderful scene.

In his previous life, Luo Wen once took Luo Wenwen to Dalongyun, although Luo Wenwen contracted the wind and cold after going back that time, but the memories of traveling together still became the most valuable property of the two.

Now, Rowan came to Da Longchu again, the time was at night when it was impossible to go to the view, and he was accompanied by Wang Yan, who had already fallen to his death.

It is said that revisiting the old place always has a warm feeling, but what Luo Wen's eyes are full of is only unstoppable amazement.

The big dragon at night is amazing!

The waterfall splashed down from mid-air, and groups of [Rainbow Slime] wandered on the shore, gathering in piles of three or five, the shimmer of the body surface flashed brilliant colors, and from time to time raised its head to spray out seven-colored rainbows that ran through the sky.

The starlight is dim, but the waterfall presents a colorful seven-colored rainbow-like spectacle under the light of the [Rainbow Slime].

The waterfall smashes down the surface of the pool, and the water vapor rushes up like a cloud of smoke, inevitably dyed with brilliant iridescent, decorating the whole waterfall with more magnificent, wonderful and romantic!

Rowan stood leaning against the boulder, his eyes slightly widened, his lips half-opened, and he couldn't help but be amazed.

Wang Yan stood beside Luo Wen, it was the first time she had seen the big dragon stream, and it was the first time she had seen such a strange scene at night, and the shock in her heart was only deeper than that of Luo Wen.

Watching the waterfall at night, the rainbow is like a flocculent, the smoke and clouds are swirling, and the rainbows are flying, what could be more romantic than this?

Her body was slightly crooked, and she unconsciously leaned on Rowan's shoulder, and a heartbeat feeling arose.

As midnight approached, the [Rainbow Slimes] gathered together gradually separated, no longer piled together, but accompanied by two and two, in pairs, composing a beautiful overture in the night.

This is the big dragon of the night, and it is the only big dragon in this world!
