Hundreds of years ago, the land was filled with the power of soul fire that everyone could grasp.

Aoki, Crimson, Clear Water, Golden Earth, Hurricane, Thunder, Wei Bing.

Seven elements give birth to seven grams, and the wheel is mutually reinforcing.

However, the good times did not last long, and a hundred years later, there was no trace of soul fire power on the continent, and there was only a new atmosphere on the continent that had changed.

Starting from the dragon crystal unearthed in the Gulong Mountain Range, it has passed through the hands of several generations to obtain a new generation of power - the technology tree!

The power operation of the technology tree is based on the burning of dragon crystals to generate dragon spirits, and then the execution of advance programming commands, but in the long history of hundreds of years, the operation of the technology tree has gradually been improved, and the cumbersome process of pre-programming commands has been omitted.

Now, the power of the tech tree is not only limited to the giant combat human fuselage that is tens or even hundreds of meters high, but has begun to slowly integrate into life, and the trams, pets, medical treatment, food, and cities where people live have also begun to slowly break away from the embrace of the earth and turn to the blue sky.

All..... It seems to be so good.

However, these are only the beauty of the rich, and they are the goals that the poor cannot achieve in a lifetime, the rich live in a clean and tidy house, and the poor only deserve to stand outside the simple thatched hut and look at the house in the target.

......

The farthest part of the continent is where dragon crystals are produced.

This dragon crystal, there is no other place, it is only produced in this ancient dragon mountain range, and the number of dragon crystals is extremely huge, and it has been collected for hundreds of years without seeing the bottom.

Occasionally, some miners want to go down to the bottom of the Gulong Mountains, but they are often gone, so gradually, exploring the bottom of the Gulong Mountains has become a seemingly impossible task.

Today, mining operations are still going on in this mountain range.

"Hey, hey!"

The miners are constantly digging dragon crystals with shovels.

This large piece of dragon crystal is colorful, as if it is as gorgeous and beautiful as the seven-colored crystal.

The workers didn't care about the view, and dug up the whole root and threw it into the minecart to dig up another one.

When the long - when the long - when the long!

The continuous sound of "dang chang" attracted the attention of the workers, and their eyes looked to the source of the sound.

"Hmm... Isn't that a little vain, why is he trying to climb down again!"

Following the worker's gaze to the almost ninety-degree vertical rock wall, a six-year-old boy was slowly climbing down with two iron pickaxes in his hands.

Some workers are already surprised, and some workers are still a little worried.

"Xiao Baibai, it's dangerous down there, come up quickly!"

"Don't worry about me, you better do your own work!"

As he spoke, he stepped into the air, but fortunately, his eyes were quick and he grabbed a protruding rock directly, so that he did not fall.

"Xiao Baibai, it's okay!"

The boy was also a little frightened, but quickly recovered.

"Ahh

At the foot of the foot is this abyss that no one has ever been to, and there is no way to explore the land of no man!

The boy took a deep breath, but the tangle in his heart still made him continue to crawl down.

When the long - when the long - when the long!

The pickaxe was waving, and he gradually disappeared from the sight, gradually descending to a depth that no one had ever descended to before.

"Wow, have you reached this place, I'm almost at the bottom!" the boy was a little happy, and he couldn't help but feel a little proud as he watched himself gradually climb down the mountain wall that had persuaded so many people to return.

The reason why this place is uninhabited is because the soil is extremely soft and there are no cliffs to climb on!

Bang ——!

The pickaxe is hollowed out!

The soft soil here directly made the two pickaxes he used to support the rock climbing useless, and the whole person fell to the bottom of the valley in an instant.

"Ahh

The terrifying screams echoed in the Gulong Mountains, and the ears of all the workers were filled with this scream, and they all left their work and ran to the edge of the cliff.

"Little white!"

"He's falling, quick, go find the rope!"

........

At the bottom of this dark ancient dragon mountain range, only the stars of dragon crystals were shining.

I saw that in the bright place of the dragon crystal, a boy crawled up in the dark.

He looked at his surroundings and chiseled a dragon crystal to use as a searchlight.

"Wow..... The dragon crystals here are all level three or four, oh my God!" he fell from a height of dozens of meters, and thanks to the exceptionally soft ground here, he was not injured.

The boy was stunned, almost all of the dragon crystals here were of high quality, and any one of them was worth several low-grade dragon crystals.

"Let me find out if there is a fifth level - Dragon Crystal!"

The dragon crystal in front of him that emitted a dazzling red light, he was stunned, this was an item he had only seen once, and the price on the market was very expensive.

The boy took a deep breath and chiseled off this small piece of fifth-level dragon crystal in a few clicks.

"Now, the gift is ready!" Long Jing was put in his pocket by him, and then continued to hold Long Jing to search.

After a few laps, I didn't find the rest of the fifth-level dragon crystals, and the highest level was only level four.

Although the fifth-level dragon crystal was not discovered, another magical thing was discovered.

A tree with a lot of fruit growing on it.

The tree pattern is very novel, the whole tree does not have a few leaves but still grows so many fruits, this fruit is also delicious, not big but slap, but unexpectedly good-looking, after eating a few in a row, the boy saw the rope from above.

"Xiao Baibai, are you still alive?" came the shouts of the workers in the distance.

After eating the last piece of fruit in a few bites, the boy shouted, "Here I am, here I am!"

After following the rope to safety, everyone breathed a sigh of relief.

"Little Baibai, do you know how dangerous this is!"

The boy shook his shoulders, "What are you afraid of, isn't it not dead!" he said, untying the rope and jumping out of the mountains.

The Gulong Mountain Range, as the only source of the Kinetic Energy Dragon Crystal of the Technology Tree, has gathered a large number of people to form the largest city on the ground.

Gulong Town.

There are millions of poor people living in this ancient dragon town, and their daily work is to go down the mountain to mine, down to the mountain to mine, monotonously but repetitively live every day.

Although the days are hard, there is still hope in this small town.

The boy trotted all the way back to his home, a simple and dusty home.

The first thing he said when he pushed open the door was, "Mom, where is Xingqian now?"

The mother, who was sewing and mending the shabby clothes in the wooden house, was stunned, "Xingqian...... She should be leaving soon, she's hovering in the field now, she's going to Jibei Taiping soon!"

"What!" the boy slammed the door and left.

A hover field is a place where a flying city is parked, usually built not far from the city on the ground.

After running for a while, he came to the hovering field, and then saw the huge flying city suspended in mid-air, and the extreme was peaceful.

"Xingqian, Xingqian, wait for me, wait for me!" He rushed into the noisy crowd at once, and saw the person he had been pursuing, she was about to step on the stairs of another world, "Xingqian, wait for me!" The boy's voice seemed to be noticed, and Xingqian stopped and turned to look at him.

"Oh, Tianbai, why are you here, didn't you go mining!" Xing Qian looked at him, and then at his palms full of small cuts, "Going rock climbing again?"

The boy looked at her and nodded, and then he quietly took out the fifth-level dragon crystal from his pocket.

"This ..... It's a gift from you, and I hope you don't forget me in the flying city!" The boy cried a little but held back, "When you go to Jibu Taipingli, I don't know how long we will see each other again." ”

Xing Qian accepted the dragon crystal, and she held it tightly in the palm of her hand.

"I won't forget you, I will always remember you!" she smiled brightly, leaving her best smile for him, "It's a pleasure to meet Tianbai, because you have made me have a sense of this gray world"

"Well, I'll always remember!" said the boy, and watched as the flying city slowly rose until it reached the blue sky that would never end in sight.

Thinking of this, Tianbai couldn't help sighing, you know, Xing Qian has brought him more than a little influence, it is her existence that allows her to discover the true meaning of life, and it is the hope she gives herself that allows her to have such a world of survival.

As the flying city was gradually engulfed by white clouds, Tianbai knew that she and she had become people of two worlds after all.

However, what he didn't expect the most was that she would say such things for herself.

"Well, forget it, even in the future, it's all worth it!"

With that, he went home.
