Ao Ertian was a high school student. 

The school taught him about second dimensional creatures. Second dimensional creatures were discovered 200 years ago, they had invaded the human world. but not successful. 

There were people who were able to recognize their identity first. and work together to deal with one of the lords of the second dimensional beings, and when the humans have won for the first time.

Humans had learned how to use a certain power by chance. A power that can be used to fight the creatures of the second dimension, and it was mana.

The very source of energy that all living beings had.

[Checking the area... A level 1 threat was detected at the direction of 10 o'clock.]

[Analyze the possibility that the host can win.]

[100%]

“100%? Can this information be trusted?

[100% Trustable]

Ao Ertian's brows furrowed together before turning to the ten o'clock direction.

“Then what should I do to be able to fight with a level one threat of second dimensional creatures? and what weapon do I have right now. You have a weapon for me. Right? system.”

[Yo do have weapons and it’s a fist or fists. right and left]

“...........”

Ao Ertian was speechless and sighed. But if the system says so, it can't be helped. Ao Ertian slowly walked forward, step by step, he lowered his body out of instinct.

1 meter, 2 meters...

Ao Ertian walked until he reached a high hill then he looked down from there.

Ao Ertian looked down from the top to the bottom of the high hill, and was surprised when he saw what was below.

"That's a second dimensional creature."

Ao Ertian hurriedly lay down so that the thing below him could not see him.

What was below stood on two legs and had a body like a human. But its skin was very red like blood. it wore torn rags and in its hand held some bone while making a strange sound.

“System analyzes the battle for me. How am I supposed to attack from here?”

[Analyze... The system advises the host to find a huge rock to throw at it from the hill.]

“Good advice”

Ao Ertian nodded. The system’s suggestion was the same as Ao Ertian had thought. He looked around and saw that there was a huge red rock near him. He hurriedly pushed it up the hill.

It was extremely heavy for a Level 1  body like him but using some tricks can help him. He used a small rock to prevent the huge rock from rolling down the hill.

"Well, don't blame me, Please blame the system."

Ao Ertian let out a sigh before pushing the rock down the hill.

A huge rock fell from the hill. The path was precisely directed towards the head of the second dimensional creature below.

*Bang! *

The rock missed the target a bit but slammed onto the right shoulder of the second dimensional creature below, its body was crushed to the ground.

[Congratulations, Host succeeded in killing -Lv.1 Red Goblin- ]

[Absorb -Lv.1 Red Goblin- resources to convert them into energy for the host.]

[Congratulations, the host has been promoted.]

[Inspecting host body… Ding!... Host's body strength is now level 2.]

Ao Ertian now felt that his body was strengthened. The exhaustion he was experiencing now had completely disappeared.

“Well to find resources to upgrade my body. I will have to deal with such creatures right.”

[Host is right, the host has killed the red goblin. The weakest creature in the second dimension. The information resources absorbed from the Goblins with body strength Lv.1 made the host's body of the same level to become stronger.]

“What is an information resource?”

[Information resources are things that are recorded in the form of energy since birth. The system is able to absorb those resources only when the organism ends, causing the information resource to flow out of the body and return to the origin.]

“Information resources recorded at birth It sounds a lot like mana, doesn't it?”

[Host is right, an information resource, in other words, can be called mana as well.]

“……”

Ao Ertian let out a sigh of relief. The resource was not something weird, and the system would only absorb and bring it to enhance the stats of his body.

And while Ao Ertian was thinking,

[Ding discovered Red goblins, Lv.1, direction 3 o'clock, 3 units]

The system alerted him. But this time, the system can distinguish the types of creatures.

"okay..."

Ao Ertian was slightly confident before walking down the hill. and walk to the 3 o'clock direction 

Ao Ertian discovered three more red goblins dressed in rags.

“This time, there are three of them, I can't use the same tactic.”

Ao Ertian stood and watched the movement of those goblins for a moment. before thinking of something

“This method should work. But I can not make a mistake.”

Ao Ertian slowly walked towards the withered bush before bending down. He looked at the three goblins walking aimlessly. And as soon as a goblin came near him, he whistled.

The whistling sound immediately entered the ear of the nearby Goblin. The red goblin was not intelligent. He heard a whistling sound and immediately thought it was the sound of an animal. It dashed towards the dry bushes where Ao Ertian was hiding. He was separated from the other two.

"Really stupid"

Ao Ertian said with an evil smile. Red Goblin when it reaches the bushes. Ao Ertian did not delay. He lunged forward, grabbing the Red Goblin throat and pressing it against the ground. And as he was pressing Red Goblin against the ground, something happened.

*Crack!!*

Ao Ertian, ​​holding onto the goblin's neck, it felt as though he was grabbing a dry branch. The Red Goblin neck was broken the moment Ao Ertian pressed it to the ground. He died so easily.

"Huh"

Ao Ertian was slightly shocked. He only wanted to hold the goblin and press it to the ground. Before smashing it with a stone, but he didn't think killing the goblins would be this easy. He needed to control his strength.

[Congratulations, Host succeeded in killing -Lv.1 Red Goblin-]

[Absorb -Lv.1 Red Goblin- resources to convert them into energy for the host.]

Once again, Ao Ertian felt that his strength had increased again.

“System, compare me now using a normal level measure.”

[Analyze the data for comparison. The host's body strength is Level 2, equivalent to a two star bronze level warrior in the normal measurement.]

“Body of Lv.2 equivalent to a two star bronze rank warrior, then what about mana?”

[The host still cannot use mana because the host core is still locked.]

“...still cannot use mana. So how can I unlock it?”

[Hosts need to find more resources. Resources that the system cannot convert directly. due to insufficient information.]

“What does that mean?”

[If the host wants to unlock the core and awaken the mana in the host It is recommended to find a Mana Stone.]

“Mana stone?”

Ao Ertian thought that the system would be able to allow him to use mana. He can’t afford a Mana stone. If he had a mana stone, would he risk killing a second dimensional creature for resource?

The minimum price for mana stone was 50,000 credit, which was quite a high price. There was absolutely no way for a commoner family to earn that much money. Today, just living every day His family was still in trouble.

Ao Ertian sighed in disappointment.

“Well, being a warrior is also good.”

Not being greedy was a good thing. With just the body of a 2-star Bronze rank warrior, he was already able to find a good job. He didn't have to aim high yet. With this power, it was already making his life more comfortable.

“Now that's it. Let's deal with the remaining two goblins first.”

Ao Ertian threw away all the thoughts that were currently bothering him. and chased the other two goblins. using the original method

[Congratulations, Host succeeded in killing -Lv.1 Red Goblin-]
