Creak!

Lin Chen pushed open the door of the house in the dust, and saw the scene of the family waiting for him to come back for dinner in the small living room, although he didn't know how many times, he still felt warm.

"Brother~ Where have you been?"

As soon as Liu Wan saw that Lin Chen's clothes were stained with blood, she immediately walked up anxiously and said worriedly: "Xiao Chen? Alas... How did you get all this blood? ”

“… Mom, I'm fine, this blood isn't mine! ”

He had already washed the blood off his face on the way, and there was really nothing he could do on his clothes. It's too late, so I have to come back like this.

"Are you going to the grain boundary again?" Lin Deming, who was sitting on the chair, directly guessed that Lin Chen had gone out in the morning, and only now did he come back to go to the grain realm, so his face was a little unsightly.

"Mom, Dad, I'm really fine!"

Liu Wan tugged at Lin Chen's clothes, and found that it was indeed only blood on his clothes, so she was relieved, but she was still worried: "Xiao Chen, the grain realm is really too dangerous, I heard that many mecha warriors died in it, let's not go now!" ”

"Okay, I know Mom, let's hurry up and eat, I've been hungry for a day!"

……

The family had dinner. Lin Chen returned to his room.

After carefully hiding the eight elemental crystals harvested today in the wardrobe from the pocket of his pants, Lin Chen went to take a shower. When he came back, he locked the door and took out the god-killing flame.

"Huh? It's been more than two hours, why is it still 9% energy? Lin Chen looked at the tail of the gun, the still dim Huang-type energy device, with a strange expression.

"It can't be because of the increased power that the 'Huang-type' energy device has a problem, right?"

Thinking of this, Lin Chen suddenly became anxious, the nerves are mecha firearms, the most important thing is the energy device, if something goes wrong, the entire firearm will be scrapped!

"MMP, Lao Tzu spent all his belongings to buy the baby... No, it's not just..."

Putting the heavy gun more than one meter long on the bed, Lin Chen looked at it for more than ten minutes, but he didn't find any problems. However, just when he was at a loss, he suddenly found that the energy of his heavy cannon had recovered to 10%.

"What's going on?"

At this time, Lin Chen was stunned, and the energy could be automatically recovered, indicating that there was no problem with the 'Huang-type' energy device, and there was no problem with the firearm, so...

"Could it be a problem with this temporary time space?" Lin Chen frowned and looked at the black crystal card like a nail in his hand.

Then quickly took out the communication device to find relevant information.

After 10 minutes.

He finally understood!

No wonder this morning, the proprietress didn't look for herself to collect money, it turned out that this temporary time space was originally a gift, a worthless thing.

I was afraid that she would collect money again, so I ran away in a hurry, it turned out... A temporary time space like him, where he can only hold one firearm, is not worth anything at all!

Moreover, mechas, mecha vehicles, mecha chariots, battleships, etc., cannot automatically recover energy in the temporary space.

You can only take it out and it can be automatically restored.

In the outside world, it takes about a day for a Huang-level energy device to automatically recover to 100%!

However, when placed in the space-time bracelet, this recovery speed will be increased by as much as 3 times!

"No wonder... The space-time bracelet needs at least 300,000 crystals, so it turns out that it is still useful! ”

Lin Chen looked at the temporary time space the size of a fingernail in his hand, and he was extremely disgusted, no wonder when he was in the grain boundary during the day, he always felt that his energy could only go in and out...

After figuring it out, Lin Chen secretly stuffed it under the bed in order to restore the energy of the Godslayer Flame, and then he fell asleep with peace of mind.

……

Monday, 6 a.m.

Last night was the most comfortable sleep Lin Chen had in so long.

After washing up and having breakfast, we rushed to the motorized rail station.

He came very early today, and Jiang Wanting's sister and brother hadn't come over yet, so Lin Chen waited for a while.

At 6:45, the two arrived together, and the three got into the car and rushed to the school as usual.

It's already 7:15 when I get to school, and if it's this time on weekdays, the school may still be quiet, but today because it's the day of the test, all the students came early!

Then Jiang Wanting went to her second class training room, and Lin Chen and Jiang Zhihui walked towards the fourth class.

On the way, Jiang Zhihui took off his eyes, wiped them and put them back on, and suddenly said a little depressed: "Alas... It's another test, Lin Chen, do you say I have no way out? ”

Lin Chen frowned, not knowing why he suddenly said this.

Although Jiang Zhihui's talent is not high, and his physical performance has always been poor, Lin Chen knows that he doesn't focus on physical fitness genes at all, but likes to study mechanics.

"Didn't you say you liked mechanics? How was this time? ”

"Alas... Don't mention it, I just found some materials and books, how can I have the money to buy those materials for experiments! Jiang Zhihui's whole person is like a frosted eggplant, without the slightest fighting spirit. After all, whoever it is, it is inevitable that you will be a little frustrated in the face of such a dilemma.

What's more, he was just a child from a slum family.

"Don't be discouraged, when I become a mecha warrior in the future, I will help you get materials!" Although Lin Chen said this with an element of comfort, he actually thought in his heart that if he had the ability to help, he would definitely spare no effort!

Because the two professions of mechanic and pharmacist need to spend a huge amount of money in the initial stage, otherwise it is impossible to get started!

The former requires a lot of crystals, materials, and devices to do experiments, and the latter needs a lot of bottles and cans of medicines, specimens, and the flesh and blood of the desolate demons to practice blending, so it costs money!

And now Lin Chen doesn't have the ability to help him!

Five minutes later, when the two of them walked into the training room, Hou Jinglin was already there.

When everyone arrived, Hou Jinglin led the four long-awaited students to the first test of the month.

"Didi-"

After the data debugging is completed, the first one is still Tan Yue......

……

Two hours later, Wu Feng also walked out of the simulation space, this time he was not as proud as half a month ago, because the overall ranking was 29!

His average strength is 495KG, and the rest of his results are the same as last time, all of them are B grades.

Seeing that Wu Feng, who had the best grades, had only a B-level fighting score, all the students were a little disappointed, obviously they had been excited in vain these days!

It was a bit of a fantasy for them to want to reach an A-level grade in martial arts and use the school's time and space gate to enter the crystal realm freely!

Next is the speed detection.

This time, Hou Jinglin did not let Lin Chen go first, but according to the list.

An hour later, when it was Lin Chen's turn to test, Yue Jing suddenly walked up to him and reminded.

"Don't forget what I told you last week!"

Lin Chen looked at her nervous and serious little face, and nodded helplessly.

Low profile! In fact, even if Yue Jing didn't remind him, Lin Chen understood it in his heart.

"Next! Lin Chen! ”
