The four-headed dragon stuck its head into the cave, stared at the amber vertical pupils and looked deeply into the cave, and then opened its three-petaled mouth wide.

Spraying venom again?, Greene carefully ducked to the side, observing and thinking.

Only this time the four-headed dragon was no longer spewing green venom, but a foul-smelling white gas.

Greene was startled, and before he could think about it, he heard Nibel shout in his head: "Little forest, this is swamp gas! If you don't want to suffocate to death, you better run!"

"Damn, biogas?! And that ability?" Greene screamed, turning around and running deeper into the cave with the beast and the Book of Dragons in his arms, with no choice but to go.

"Haha, Xiao Linzi, the four-headed dragon has such an ability!"

"Its four heads mean it has four different abilities: one can secrete an enticing scent similar to a dragonberry, one can spit green venom enough to corrode metal, and another can secrete a clear glue that hardens when it sticks, and now it can spit out rancid gas similar to methane!"

"When it encounters a predator, it can scare away even the hungriest giant dragons with a gentle spray of this pungent putrid gas. ”

Stumbling through the black cave, Greene covered his painful head and said in pain, "This is really a suffocating ability!"

People really can't be scared, he just held a venting attitude and simply teased the four-headed dragon, but he didn't expect to attract such a result!

There was no way back now, he could only continue along the dark and winding cave, and he had no time to think about what lay ahead.

......

"Hiss~"

"Meow Meow~"

Rubbing the bridge of his nose that had almost been broken, Greene was thinking about whether he really wanted to keep walking, when the little beast above his head suddenly "meowed" and stomped left and right on his head.

"Xiaolinzi, it's reminding you which direction to go, understand?"

Greene was slightly stunned, and then saw the little beast's shining green eyes in the dark environment, and immediately understood.

"Hey, this little guy still has night vision?"

"Hehe, most dragons have this ability, and it's not unusual. Nebel replied casually, and then fell silent.

Just as Greene wondered why he didn't speak, the sound of flipping through the book sounded in his head, and he touched his nose speechlessly: I didn't know that this old guy was addicted to that novel lately.

At the suggestion of the little beast, Greene walked silently in the dark cave, although it was still not easy to walk, but at least now he would not hit the mountain wall.

After walking for a long time, he still couldn't feel the end of this deep cave, and Greene couldn't help but feel a little apprehensive in his heart.

"Little one, you look like a cat and a squirrel, and you have learned to meow, so I'll give you a name. Greene pretended to be relaxed and said, "Well... Just call it meow meow, hehe!"

"Meow~"

"Haha, I didn't say I objected, I agreed!"

"Meow Meow~"

......

After walking alongside for a while, he suddenly noticed a glimmer of light in front of him, and the further he went, the clearer he could see, and Greene suddenly sighed: It seems that there is still an exit ahead.

A few more steps forward, and before he could see the exit, the sound of crackling water sounded in his ears, and then he turned a corner, and his eyes suddenly opened up.

This exit is completely opposite to the cave when you entered, narrow inside and wide outside, and there is a huge waterfall hanging outside the entrance.

After Greene drilled out the curtain of water, what he never expected was the scenery outside the cave:

It is a valley surrounded by mountains.

At the entrance of the cave is a huge waterhole, into which a waterfall cascades down the mountain.

In the middle of the valley, not far from the waterhole, there is a towering oak tree, the oak tree is surrounded by red flowers and green grass, butterflies fluttering, the whole valley is like a fairyland.

Meow Meow was noticeably more lively when she reached the valley, jumping from one shoulder to the other, and then to Green's head, spun around and screamed excitedly.

Greene pinched his neck helplessly and lifted the naughty little guy to his face and said, "You little thing doesn't like people to touch your ears, and I don't like something to step on your head!

As soon as he put Meowth on the ground, the little guy quickly climbed up along his body again.

At this time, Ge Lin suddenly remembered that the little beast's original injured body recovered quickly, but he never regained the ability to fly, what was going on?

When he wanted to bring Meow Meow in front of him again to see what the reason was, a yellow shadow suddenly swept from the corner of his eye and flew towards him from the sky, followed by a flash of lightning.....

Greene only felt numb all over his body, and he suddenly fainted as soon as it was dark in front of him.

＊＊＊＊

Greene felt as if she had been dreaming for a long time.

In the dream, he became a teenager named "Green", living in a Viking kingdom composed of many islands, the "Kingdom of Navia", and the island where the tribe to which he belongs, the "Thor's Tribe", is called "Dragon's Tooth Island".

Almost half of the 12 months of the year are cold winters, while the other half is a comfortable season, where people graze, fish, hunt, stock up on food, and wait again to survive the long and cold winter.

Day after day, year after year.

In a word: life is difficult, the environment is harsh, and survival is difficult.

And what's even more exaggerated is that there is a strange creature that has existed in this world for tens of thousands of years, more than beasts:

Dragon!

These dragons come in a wide variety of species, sizes, and with all sorts of strange abilities of their own, they are unscrupulous, often causing trouble, scourging livestock, and sometimes even killing some hapless Vikings.

Green, the son of a locksmith.

Originally, with his father's lock-making skills, he still lived a relatively comfortable life, but when he was out hunting, his father was killed by a two-headed dragon, leaving only 12-year-old him and 5-year-old sister.

After four long winters, Green and his sister, who had not learned much about his father's locksmithing, had become increasingly difficult, so he was desperate to change his hungry life.

Just after his 16th birthday, the opportunity finally presented itself.

King Harald III of the Kingdom of Navia suddenly announced that he would choose a husband for his only child and daughter, Princess Victoria, known as the "Viking Elf".

The selection will be open-ended, and any Viking of the right age, whether aristocratic or free, can sign up.

The first prerequisite project selected is to slay the dragon!

Only a Viking warrior who slaughtered a dragon with his own hands could make it to the second stage of the selection.

Green, who also knew that marrying a good wife and at least twenty years of struggle would save twenty years, quickly signed up, and with the attitude of avenging his father, he chose to slaughter a two-headed dragon.

Double head means double attack power, and Green, who has never been trained to be a professional dragon slayer, quickly suffers for his choice.

When he plucked up his courage to rush towards the two-headed dragon alone in the wilderness, he was knocked unconscious by the tail of the two-headed dragon.

When he woke up again, he found that he had been caught by a two-headed dragon and flew into the air, with white clouds and blue sea below.

Green prayed to the gods that the two-headed dragon would not let go, but his luck was apparently not good.

Just as they were about to reach a towering snow-capped mountain, he was thrown from the air by the two-headed dragon at once, and looking at the rapidly approaching white earth, Green could only scream in horror:

"Ah!!!
