Interstellar calendar 2009, Earth, Central Plains Continent, Qingshui Town, Lihua Mountain.

In the mountains and forests, a young man and an old man are slowly advancing.

The young man's name is Gu Tong, he looks about eight or nine years old, with a clean face, short black hair, a black sweatshirt, and the big bamboo basket behind him is completely inconsistent with his small figure, but there is no trace of tiredness on his immature little face, but full of excitement and curiosity.

Gu Tong said to the old man walking in front, "Grandpa, what kind of herbs are we looking for this time?"

The old man's name is Gu Bai, and he is Gu Tong's grandfather.

Cooper stopped, looked at the jungle below the mountain with his old eyes, stroked his goatee on his chin, squinted his eyes and said, "Don't hurry, let's go into the mountains again, and you will know when the time comes." ”

In this way, the old and the young continued to bury their heads in the mountains and forests.

......

Under the scorching sun, Gu Tong and Gu Bai were resting under an ancient tree.

Suddenly, Gu Tong looked up at the wild fruits on the tree and said, "Grandpa, look, there are wild fruits there!"

Gu Bai slowly looked up at the ripe fruits above his head, and said with a smile: "See, slow down when you pick it!"

"Got it!"

As soon as Gu Tong's words fell, the light blue light under his feet shone, and he ran on the trunk of the tree as if he was walking on the ground, and the light under his feet flashed again, and his body flew to the thick branch like a spirit monkey, and his movements were as coherent as flowing water, and it was only a few seconds to leap from under the tree to the branch of more than ten meters, and not even one of the herbs in the bamboo basket on Gu Tong's back did not fall out.

Gu Bai sat under the tree and watched Gu Tong climb the big tree so quickly, with a pleased smile on his face, and said: "Look at the use of this child's first son is really like his father, he has been a worry-free person since he was a child!"

...

In this time and space, there is the element of the first son, in the words of our time and space, it is magic or mana, and some people in this time and space, they can control the first son that exists in nature from the time they were born, improve their physical ability, make things or fight, but since human beings discovered that they can control this element to make things, they have found a drawback, that is, people cannot use the first son to make scientific and technological products and food or more complex things made by humans, even if they are made, because this kind of thing will not have any practical effect and become the first child to dissipate in the natural world again。

......

After a while, Gu Tong picked a whole basket of wild fruits, and Gu Tong took out a wild fruit and threw it to Gu Bai.

Gu Bai casually raised his hand and received the wild fruit, and asked, "Tongtong, how much of your heavy metal has been completed?"

When Gu Tong heard Gu Bai's words, he scratched his head and said, "Uh... I'm only 50 percent done with heavy metal. ”

"Fifty percent? ”

......

Heavy metals, since the birth of human beings in ancient times, they found that the human body absorbs the primordial elements in nature will make the body as hard as metal, and its sign is to form a metal-like luster on the surface of the skin, in other words, the body becomes invulnerable.

......

Gu Tong jumped on a big bluestone, his hands into fists at the waist, the horse step was deep, the light blue light shining all over his body, there seemed to be a light blue mist in the air around Gu Tong, and finally attached to Gu Tong's skin, and this light blue mist was the first son.

Suddenly, the light blue light disappeared, and a buzzing sound came from the bluestone under Gu Tong's feet, Gu Tong's skin began to turn into a metallic silver-white, shining dazzling in the sunlight, but this silver-white skin did not cover the whole body, from the face and neck, only half of the body.

Gu Bai looked at Gu Tong's half silver-white and half-normal skin, his wrinkled right hand was gently clenched, the first son in his hand gathered, a small knife appeared in his hand, his fingers curled, and the sharp knife stabbed Gu Tong with cold light.

Gu Tong didn't dodge, but stood there motionless, his silver-white skin flashed, and there was no blood splashed, but the sharp knife was bounced away.

At this time, Gu Tong stretched out his silver-white left hand and grabbed the knife, and a sore metal sound came, and the sharp knife was pinched into iron powder by Gu Tongsheng, and then turned into a light blue light and dissipated into the air.

Gu Bai watched Gu Tong pinch the knife into iron powder, and scolded with a smile: "You stinky boy, you run around in the mountains all day long after school, and now the heavy metal is only fifty percent complete, wait for your dad to come back and see how your dad cleans you up." ”

Gu Tong heard that his grandfather was going to sue his father, and the silver-white skin on his body instantly returned to normal, and he hurriedly jumped to Gu Bai's side and said, "Grandpa, don't do it, my dad hurts a lot when he beats people, grandpa." ”

Gu Bai couldn't stand Gu Tong's soft grinding, and hurriedly said: "Okay, listen to you, but you remember, when your father comes back, you must practice heavy metal to seventy."

Gu Tong's little head nodded like a chicken pecking rice, and said, "I know, I will definitely do it." ”

"Alright, go inside a little further and try to get back before dinner. ”

......

The remnant sun is like blood, the ancient peers walked in the jungle, the immature little face was slightly tired, although he was a capable person, but after walking in this mountain for a day, the body was also unbearable.

Seeing the tiredness on Gu Tong's face, Gu Bai sighed and said, "Alas, it seems that I can't find it today, let's go, while we can still see the mountain road clearly, let's go back quickly." ”

When Gu Tong heard Gu Bai say go home, he shouted, "Okay! You can go home for dinner!"

Just as the two of them turned to go down the mountain, there was a loud bang, and a bright point of light appeared above the sky.

Gu Bai looked up at the sky, his cloudy eyes shone with a light blue light, his face instantly turned pale, and the skin of his body instantly turned silvery-white, grabbed Gu Tong and rushed down the mountain.

"Grandpa, what's wrong?"

"Don't ask so much questions yet, hurry up and recover your strength!"

Gu Tong looked at Gu Bai's serious face and hurriedly closed his eyes and meditated.

But before the two of them had run far, the clouds above the sky dome rolled up, and finally they were broken by a firelight, and a huge meteorite carried a blazing high temperature from the sky, and the powerful destructive power directly destroyed this mountain, and the mountains and rocks collapsed in an instant, and the lush jungle instantly turned into a sea of fire.

Gu Bai looked at the menacing flames behind him, the light blue light in his hand shone, and slapped his palm on Gu Tong's body, forming an egg-shaped protective cover on Gu Tong's body, sending Gu Tong down the foot of the mountain.

Gu Tong, who was meditating, knew Gu Bai's thoughts and shouted, "Grandpa, let me out!"

Gu Bai smiled slightly and said, "Don't worry! Your grandfather is very powerful!"

The fire was like a python, and it swallowed the ancient cypress in an instant.

......

The sound of rushing water woke Gu Tong from his coma, Gu Tong struggled to get up, found himself on the edge of a waterfall, remembering what happened before, Gu Tong hurriedly looked at the place where the meteorite fell, on the other side of the dense forest, billowing smoke rose, and the strong fire seemed to illuminate the night.

Gu Tong looked at the billowing smoke and couldn't help but curse angrily: "What's the situation!?Where did the Earth Defense Force go? What did the defense satellite do to eat? The meteorite squeaked when it fell? I don't know if grandpa is okay?"

Gu Tong thought about it, and he didn't bring his mobile phone now, so he had to go home first, and found his bamboo basket on the side, fortunately, the herbs and wild fruits in it were not lost too much, and he walked down the mountain with the bamboo basket on his back.

But before he could walk, Gu Tong felt as if something was following him behind him, and he paused in his footsteps, and there was a rustling sound in the grass.

Gu Tongxin thought that it was night at this time, and it was the time when the wild beasts in the mountains came out to feed, Gu Tong saw that the wild fruits in the bamboo basket were less than half, and thought that it would be better to hunt a game for his mother, and when his grandfather came back, he would also honor his old man.

Without further ado, Gu Tong's figure turned sharply, the light blue light in his eyes shone brightly, the first son in his hand gathered, and the two knives were held in his hands, approaching the bushes.

Something in the bushes seemed to sense the danger and hurriedly dodged, but at this time, the knife in Gu Tong's hand was approaching, and the cold light flashed, and the bushes were instantly split in half.

Just as Gu Tong was about to go further, a piercing scream pierced the silent night.
