"You?" Lin Deming and Liu Wan, who were originally in a quarrel, instantly turned out their drums, and turned their heads to look at him.

"This is the 5W crystal coin that the school organized for students to enter the grain boundary a few days ago, and I earned!" As he spoke, Lin Chen took out the 5W crystal coin from his pocket.

Now the currencies between the six remaining powers on the earth have been exchanged for global crystal coins!

The maximum face value of the crystal coin is 100,000. The 50,000 crystals in his pocket, each with a face value of 1,000, can only fit into his pocket.

"Maybe in a few days, the school will organize again, and then I will kill some more crystal beasts, money... You'll be able to raise enough! ”

As soon as this sentence was finished, Lin Chen was startled by Lin Deming and Liu Wan's violent reactions.

"No, this is our business, you use this money to cultivate well for me, I don't need you kid to worry about it!"

"Yes! You earned this money at the risk, Xiao Chen listened to his mother's words, put it away, and went back to buy more potions! Mom and Dad don't have the ability, otherwise with your talent to cultivate with the help of potions, your physical fitness wouldn't be... And so now! ”

Under the stern gaze of his father Lin Deming and the gentle gaze of his mother Liu Wan, Lin Chen's nose was a little sour for some reason.

In the 21st century, he lost his parents, and he was extremely eager for family affection, but now under the care of his father and mother, the whole person has become a little unnatural.

"Dad... Mom, it's okay, you know my talent, it's not bad for this little potion, and Xiaoxue is also my sister, so you take this 5w first, and I will try to raise the other 15w during this time! ”

After speaking, Lin Chen quickly got up and escaped from the living room and returned to his room.

Closing the door, Lin Chen looked at his messy room, a slight smile appeared on the corner of his mouth.

Before coming back, he was still nervous because of Lin Chen's parents and sister, but now, he has wholeheartedly accepted this new identity and likes this home!

Especially, that cute Kobayashi Xue who looks very similar to his sister!

"Whew! Let's clean up the room first! ”

……

Night.

It was already past ten o'clock after Lin Chen finished cleaning up the room, and he was sitting at the head of the bed, took off his shirt, and began to bandage the wound on his chest.

Before ten o'clock, he was afraid that his parents would suddenly come in, so he didn't treat his wounds, but now at this time, they had already slept, and Lin Chen was relieved to deal with his wounds.

Accidentally touching the top of his chest, the four deep bone-deep claw marks, Lin Chen's painful cold sweat broke out.

Then he took out a small bottle of potion from his pocket and applied it.

The liquid in this transparent small bottle in his hand was only five grams, which cost him five thousand yuan, and this kind of medicine was just the most ordinary medicine for healing wounds, and if the effect was better, it would be even more expensive, each gram was more than 2,000 or 5,000!

He doesn't have that much money, so he can only use this kind of medicine with the worst effect, and the 5,000 crystal coins have been saved for a long time, and he is going to buy physical energy potions to help with cultivation, and as a result... Spend a fine light.

It can be seen that in today's world, you really can't live without money!

After all the five grams of medicine were applied to the wound, Lin Chen was already sweating profusely, and finally endured the severe pain of fainting, bandaged the wound, and then lay on the bed in prostration.

And he was about to go to the toilet to wash his face when his door suddenly opened.

Then through the crack in the door, a small head came in.

"Brother~ Have you slept?"

"Little... Qing..."Lin Chen, who was almost called by the wrong name again, quickly changed his words and said, "Xiaoxue, you haven't slept yet?" ”

Xiao Lin Xue saw that he was not asleep, so she slipped in sideways, walked to Lin Chen's bedside, and screamed obediently. "Brother~"

"Xiaoxue..."Lin Chen was a little strange, Lin Xue, who was barefoot in his sight and holding a brown bear doll in his arms, looked unusually well-behaved, and did not have the naughty appearance in his memory.

Even those big jewel-like eyes did not have a lot of wisdom, but looked at themselves and became a little red.

Lin Chen moved to the side of the bed, reached out and touched Lin Xue's little head, and said gently, "What's wrong?" ”

“… Elder brother... I... I" Lin Xue I didn't finish for a long time, and finally only spit out a sentence "Thank you!" He hung his little head.

Lin Chen was not stupid, although she didn't say it, she still guessed that Lin Xue was afraid that Lin Xue already knew about her parents' quarrel, so she opened her mouth and comforted: "Okay, hurry up and go back to sleep, don't you still have to learn physical fitness tomorrow?" The matter of tuition, brother must have solved it for you! When the time comes, there will be another little genius in the physical fitness school! ”

"Brother..."

"Let's go back!"

After watching his sister Lin Xue close the door, the tenderness in Lin Chen's eyes slowly became heavy.

"It seems that another 150,000 must be raised during this time!"

Although he has a heart, he also feels a headache for this huge number. If the money was so easy to make, he wouldn't be able to cross here!

And the world ......

Since crossing into this world in the afternoon, Lin Chen has not had time to sort out the memories in his mind, and now that he is free, he has begun to rethink this world!

'Crystal' era! This is a new era of technology and element integration!

In his mind, Lin Chen didn't have much knowledge and knowledge of the Crystal Age, so Lin Chen only knew that the human race had entered the Crystal Age of a new realm from the nuclear age before the 25th century (Demon Famine Century), completely with the help of the 'Crystal Beast' in the grain boundary!

And this is also the real reason why human physical fitness genes and civilization can be improved as a whole in just 300 years.

As for the older 'Demon Famine Century', he knows even less, but through history textbooks, he simply knows that the age of the Demon Famine Century is the 22nd century ~ 24th century!

At the beginning of the 22nd century, in order to explore the galaxy and find a new life planet, human beings accidentally exposed the coordinates of the earth in the universe, thus encountering a large-scale invasion of the 'desolate demon'.

And in those 200 years, it was the darkest era of human beings on the earth, hundreds of large and small countries and regions were reduced to ruins in an instant, and the nuclear weapons of human beings could not play much lethal power against the desolate demons at all, and in the end, only six countries including Huaxia were left.

Just when the earth's civilization was on the verge of extinction, the six great powers united and barely survived the apocalypse.

During the darkness of more than 200 years, human beings have never stopped looking for light in the darkness, and finally in the middle of the 25th century, after human beings discovered the grain boundary (planet) through the gate of time and space, human power civilization began to rise again......

After the nuclear age entered the crystal age, humanity began to resist the invading desolate demons and re-establish cities, cities, and even today.

However, to this day, most areas of the earth are still occupied by desolate demons!

……

Memories go back to the crystal era of the 28th century.

Strength, speed, nerves!

The cultivation of these three physical energy genes, like the crystal beasts in the grain boundary, is divided into ten levels, which are 1~10 levels. After breaking through, you can equip the corresponding level of mecha weapons! Become a Mecha Warrior!

There are three physical genes, and the mecha weapons equipped are also divided into three different series!

'Power & Defense Series Mech' 'Attack & Speed Series Mech' 'Long Range Bomber Series Mech'

This is the connection between physical fitness and crystal mechas!

If the 'mecha' is a weapon that exerts the 'physical gene', then the 'crystal element' is the fundamental that determines the strength of the mecha's equipment!

Strength system: Strength and defense series mechas, which can use the crystal elements of fire, earth, and water, so as to strengthen the mecha, integrate with scientific and technological weapons, and finally form super mecha skills.

Speed system: Speed and attack series mechas, which can use the crystal elements of wind, thunder, and ice.

The neurological long-range bombing series mecha can use the crystal element of six attributes.

This is all he knows about the 'physical fitness genes', 'crystal mecha', and 'crystal elements'......

"It's like... It's so similar! ”

When Lin Chen sorted out these memories, he suddenly found that the crystal mecha of this era was very similar to the crystal game he played in the 21st century!

Strength, speed, nerves, and three physical fitness gene cultivation methods, just corresponding, in the grain boundary game, warrior, knight, and long-range division three major professions.

Moreover, the connection between the mecha weapon and the crystal element here is exactly the same as the connection between the mecha equipment and the crystal beast in the mecha game of the grain world.

Both turned out to be enhanced mechas!

Moreover, the six attributes of the crystalline element are also exactly the same, fire, earth, water, wind, thunder and lightning, and ice.

It's just that there are still two crystal beasts with super attributes in the crystal boundary game, light and dark. I don't know if there are these two properties in the grain boundaries here.

After thinking about it, Lin Chen didn't get any more information.

There is no way, the body owner lives at the bottom of this world, and many things are not known at all. And he is the strongest one standing at the top of the pyramid in the grain boundary game, ranking among the eight professions!

However, there are also many differences in this world, such as after the fourth order!

After the physical fitness gene breaks through to the fourth order, it is said that it can be equipped with a stronger 'body', so as to soar in the air, and after the mecha weapon and the body are perfectly integrated, the power of the attack is enough to destroy the city and shatter the galaxy!

But in the Grain Boundary game, there is no equipment for the body at all.

"It seems that there is time, we must go back to the grain boundary and find out!" Lin Chen thought to himself.

If, as he thought in his heart, the current earth uses the gate of time and space to connect the grain boundaries, which are similar to the grain boundary games he plays, then...

Lin Chen didn't dare to think about it anymore, because he knew that if it was really the same, then at least before the sixth order, all his cognition in the grain boundary would be clearer than any human on the earth!

As for... After the sixth order, there is no way, and his game character is only level 60...

But... Sixth Order! It's totally enough!

"Whew!" After sorting out the memories in his mind, Lin Chen was suddenly full of infinite confidence in the era in which he lived!

"Lin Chen! Since I possess your body and your memories, you are me from today onwards! I am you! Everything you have will also belong to me, so don't worry, I will take good care of this family, as well as our sister......"
