Lake Evans lies quietly on the fourth dead mountain in the northwestern part of the Kotstein Mountains, the pale blue water is as flat as a mirror, and the blue-gray limestone is dotted with green shrubs and black lichens. Gray, green and black crisscross and weave into a dark scarf that surrounds the beautiful Lake Ewens, serene and elegant.

Rainon and Fiona walked around the oval Lake Owens, and the nightmare followed silently, and in a few moments they came to a small stream at the source of the Wushui River. The clear waters of Lake Erwens gushed out of that small gap, and they ran down the slope singing merry songs, and every time they touched a rock, they stirred up white flowers and flowed into the dark green jungle in the distance.

"That's it. Ruinon's gaze followed the water and flowed down to the Black Forest in the distance, and he silently said in his heart, "I believe this is the new beginning of my life." ”

Fiona looked up at the blue sky, letting the fresh mountain breeze blow through her silky hair, reflecting a brilliant golden color in the bright sunlight.

"It's beautiful!" said Ronon with a sideways glance.

Fiona smiled and said, "Thanks, thank you, didn't you say you were going to look for something along the river? It's not early, the Black Forest at night is terrifying." ”

"Well, I wish we could find the hole in the dead branches before it gets dark. Let's go!" said Rinon and stepped onto the nightmare's back again. With a hissing roar, the nightmare spread its hooves and leapt into the sky, leaving a long black flame in its wake. Fiona once again harnessed the Qi Elemental and followed closely behind, and after a long run, there was not a trace of exhaustion on her white face.

"Boy, you're very discerning! You can get such a beautiful elf. Not only is she beautiful but also very strong, have you ever pushed it?" the nightmare chattered again during the long journey, "I don't know what it tastes like...... Gee. It smacked its lips.

"What is it that you don't push? I'm just ordinary friends with her, that's all, and I don't want to sink too deep into the emotional world. ”

"You're not interested in such a beautiful elf? I'm hungry and hope she's delicious. ”

"If you dare to do anything to her, I'll fight with you!" said Ruinon, pulling Nightmare's black mane fiercely.

"Ahh

"What's wrong?Rinon?" Fiona asked, hearing Nightmare's screams, as she flashed up to Rainon and Nightmare.

"I didn't ...... It's nothing ......" Renon wiped the cold sweat from his forehead and thought to himself: if we told her that we were discussing whether she was delicious or not, I guess she would kill us.

"I remember a few key points written in that diary: deciduous trees, migratory routes, and almost dry rivers. Fiona snapped her fingers and said, "Now that we have been walking along the Wushui River for a long time, it is still very full. ”

"Could it be that I guessed wrong? could it be some other river?" asked Renon, scratching at his messy hair.

"No! You can't be wrong, the Black Forest is a scarce source of water, there are only a handful of rivers and there are no tributaries to the rivers that flow into the Black Forest. "I remember very well that there was only one river in the southern Black Forest, and that the chameleon must have migrated along the Wushui River, because they needed the only water they had to survive. ”

"Really?" Ryanon closed his eyes, and an invisible meditation force field spread. Fiona and Nightmare felt a cool breeze on their cheeks and sped away. "Here!" said Ranon suddenly, pointing to his left front with his left hand, "there are different trees. Although I can't name them, what is certain is that they are different from the evergreen pine and fir trees that are widely distributed in the Black Forest because their trunks are bare. ”

"Deciduous trees...... That's it!let's go!" Fiona immediately manipulated the qi elemental and flew forward like lightning.

"How can you be more positive than me?" Rynon muttered quietly, urging the Nightmare to keep up.

The nightmare took Rainon through the dim jungle, and gradually the branches and foliage of the surrounding trees seemed to become sparse, the light became brighter and brighter, and the vision became wider and clearer.

"Is this the place? These trees...... Not dead wood. "Rinon noticed that the bare branches had green spots, which were new shoots.

"It's not here, then let's continue north. I remember that the chameleon would pass by there every year in early spring. Nightmare made a suggestion to Renong.

"That's it. ”

As we walked, the sky gradually darkened, and the sun drooped its head in the dim yellow sky.

"Stop!" suddenly the nightmare warned loudly, "there's a smell!"

"What smell? Why didn't I smell it. Ruinon sniffed.

"If you can smell it, then you're not human. Fiona drew her sword and smiled.

"Rancid smell......" Nightmare added.

"What is that?" Fiona looked around warily.

"I don't know how to do it, but I rarely come here before. ”

Ruinon patted Nightmare's neck and said, "If you don't enter the tiger's den, you can get the tiger, go, go and have a look!"

Nightmare nodded, slowly moving in the direction the scent came from. The rancid stench in the air grew stronger, and gradually both Renon and Fiona could smell it.

"There's a river!" Fiona, who is an elf, has excellent vision, which is one of the reasons why elves are good at bows and arrows!

"A river that is almost dry...... That's where the rancid smell comes from. When he came to the river, Rainon covered his nose and looked at the black stagnant water and said, "Ahem...... What is in this water, how can it emit such a foul smell?"

"It's poisonous!"

"Poisonous?" said Ruinon, looking at the black, stinky water in amazement, "Why is this river suddenly out of water? ”

"Not only is the water in the river poisonous, but you can see that even the soil in the vicinity is polluted. It's no wonder that large swaths of trees are wilting. Fiona poked her toes at the hard, dark purple soil and said, "Look, there's not a single normal tree around. The trunk of the tree is full of flocculent cavities...... It's rotten for a long time. With that, she gently poked a tree beside her with her sword, and the tree shattered into a mess of powder.

"There are black plants everywhere...... What a foul smell!" Ruinon saw a tangled mass of vines by the river, and leaned closer to his face curiously. Suddenly, a smoky stench came to his face, and Ruinon's eyes turned red and he burst into tears.

"Renon be careful! That's the black snake thorn vine, a vine plant with a lot of poison. Nightmare bit the back of Rinon's shirt and held him away from the black snake vine. (Black snake thorn vine: perennial climbing herb, the stem is hemp rope-shaped, black purple, covered with black fluff, with strong adsorption, can climb.) The leaves degenerate into spikes and are flowerless. The epidermis can secrete dark red milky juice, which is highly poisonous and has a pungent foul smell, once the poisonous juice is ingested by mistake or is stabbed by the thorn of the black snake thorn vine, the highly poisonous juice can instantly blind people, and then the heart stops beating. ）

"Black Snake Thorn Vine?"

"A terrible poisonous plant!" Nightmare's purple pupils scanned the banks of the river.

The sky darkened, and the banks of the dim river ditch were covered with dense black snake thorn vines, making the dark purple corroded earth even more eerie.

"Ahh She pointed to a black whirring shadow in the distance.

Rainon and Nightmare walked quickly in the direction Fiona was pointing.

"This ......"

"Nightmare, hit me. Renon said to Nightmare.

"What?"

"I said, hit me. ”

"That's what you said. With that, Nightmare lifted his front hooves and kicked on Ronon's back. "Bang" Ruinon flew out like a kite with a broken string, rolled on the ground more than ten times, and smashed a dead tree more than ten meters away before stopping.

"Damn! you're trying to murder me!" said Ronon grimacingly, standing up and yelling at Nightmare.

"Didn't you say I'm going to hit it?"

"But it didn't make you so ruthless!"

"Oh...... yes. Nightmare shook her head and made a sudden realization.

"It hurts! Looks like I'm not dreaming. Ruinon looked at the black snake thorn vine wall that was more than three people tall in front of him and said dumbfoundedly.

"Yes, if I hadn't seen it with my own eyes, I wouldn't have believed that there was such a large community of black snakes and thorn vines in the World Realm. Fiona grew up and said, "The Wushui River will be cut off, and the river will be polluted, and it turns out that the river is blocked by a large group of black snakes and vines." ”

"Since there is a community of black snakes and thorny vines, there must be ...... here. Red Sticky Frog. Nightmare raised his front hooves and pointed to a small red dot not far away and said, "There are a few creatures in the world that are not afraid of the black snake thorn vine toxin. Remember, Renong, don't get too close to them. This seemingly weak creature has a toxin that even dragons fear. Once they sense a threat, they will spray a deadly mist of venom from a small hole near their eyes. ”

(Red Slimy Frog: One of the rarest and rare species on the continent of Middle-earth.) They are very harsh on the environment they live in, and are only found in a few jungles in the southern part of the Middle-earth continent with humid air and abundant water, and they must have highly toxic plants near the water source where they live. The average body length of the red sticky frog is about 2~4 cm, the back has a brilliant rose red, and it is immediately dotted with several orange spots of different sizes, and the limbs are covered with scales. The red sticky frog has smooth skin and secretes toxic mucus on its surface, which can be absorbed by the skin of other animals and cause severe allergies. Once the red sticky frog senses a threat, it will spray a deadly mist of venom from the small hole near the eye, and just inhaling a small amount of the toxin can instantly paralyze and lose consciousness. The toxin of the red sticky frog can affect the nervous system of living organisms, causing the poisoned person to be paralyzed instantly, the heart stops, and finally dies. Alchemists have yet to develop an antidote. )

"Hiss......" After listening to the introduction of the nightmare, Ruinon gasped, "cough, cough, cough, cough, ......cough, cough", the stench in the air choked Ruinon and coughed repeatedly.

"Rinon, Nightmare, give way. Fiona exclaimed.

"What?" Rynon and Nightmare asked, looking back at each other, only to see Fiona raise her sword in the air, and the high-speed air currents swept around her body, scraping her clothes with a grin.

"I said get out of the way!"

"You, you...... What do you want to do?"

"This abominable black snake vine has clogged the river, polluted the water, and killed a lot of plants! After saying that, Fiona swung her sword again and again, only to hear three piercing screams that broke through the air, and then the thick black snake thorn vine wall collapsed. "Poof" sounded again, and a scorching wave of air hit, and a dark red fireball fell from the sky into the fragmented remains of the black snake thorn vine, and suddenly black smoke billowed into the sky.

"That black smoke is poisonous! Rinon use magic to create a barrier to protect yourself. With that, a light purple aura flashed around the nightmare.

Ruinong narrowed the coverage of Meditation's stance and strengthened its stance. Under the action of the hot air, the black smoke rolled and surged, and every time it collided with Ruinong's meditation position, it was as if a heavy hammer was hitting Ruinon's chest, hitting him with chest tightness and headache and blood surging.

"Hiss......" There was a hiss of snakes in the raging fire.

"Is there a snake?" asked Ronon under the pressure of the intense poisonous mist.

"Who knows? Fiona said in a cold voice, staring at the raging fire.

The sky was completely dark, the fire had finally been extinguished, the black snakes and vines that had accumulated in the river had been burned, and the clogged Wushui River was finally unblocked again, but the water was still black and emitted a disgusting stench.

Renon drew his wand and pointed it twice at the sky, spewing out a white ball of light. The ball of light floated in the air and followed Renong, emitting a soft light that was both bright and not dazzling.

"Hiss......" was another sound, which made everyone's hearts tremble.

"What's it, get out of here!" said Renon, looking around warily.

"In the water!" Fiona said, pointing her sword at a pair of green eyes in the river.

Nightmare stared at the thing and said, "It's a rotten water broad-footed lizard...... Let's go, let's go, we can't afford to mess with this thing!"

"What is that?" Rynon asked, scratching the back of his head, "and from the tone of your voice, that thing sounds terrifying." (Rotten Broadfoot: A rare giant lizard on the continent of Middle-earth, it is extremely adaptable to changing environments, and can survive as long as there is a pond that can accommodate it.) The first rotten broadfoot lizard to be found in the world lived in a pool of black, stinky stagnant water, and when it climbed ashore, explorers were shocked by its huge paws, so they named it Rotten Broadfoot. They are mainly found in the tropical jungles of the southwestern part of the continent, and have also been found in the cold steppes by explorers. The rotting broad-footed lizard is huge, with an average body length of up to 5 meters and a weight of about half a ton. Omnivores, they eat almost everything, including carrion and dead wood. The saliva of the rotting broadfoot lizard is deadly due to the well-developed venom glands in its jaw that secrete lethal venom, and few creatures can escape the clutches of death once bitten by it. ）
