"Several traversers, please open the system interface and select the Starter Pack" The cold electronic sound sounded.

Without warning, four figures appeared in a small, ownerless three-story building in Central City.

Xia Lin raised his head, and he was greeted by three companions dressed in old-fashioned European clothes.

[Hmm, did you cross over?] These days, the crossing has become rotten. It's still a group wear, it shouldn't be the kind of space class of infinite horror. That's troublesome, the four of us can fight ordinary people, but once we encounter a well-trained enemy, we will explode on the spot. Xia Lin thought wildly.

"I'll go, Lao Xia, you've changed color!" Wei Li and the three of them said in unison. The corners of the mouths of the three of them were constantly twitching, obviously holding back a smile.

"What's the situation? I'm still yellow-skinned, no problem. Give me a mirror and I'll take a look. Xia Lin didn't know why, and grabbed the makeup mirror in Wei Li's hand.

The strong afternoon sunlight in the mirror stung Xia Lin's eyes, but he didn't care at all. The soft and long golden hair became crystal clear under the support of the sun, and the young man's already extremely feminine face was beautifully set off by a pair of golden eyes.

"Well, this hair length can be used for women's clothing in the future." Xia Lin was extremely satisfied with the change in his appearance, and blurted out an astonishing comment.

"Arin, do you think that's the point? With blonde hair, you probably won't be able to mix in the steel world......" Li Ruoge sighed. "The villain in the bottle sees you and it's over, Hohenheim or something better not to have anything to do with it."

"Calm down, blonde hair is not an exclusive trait. Why does Lao Xia's hair change color is a problem, right? The skin color and hair color of the three of us have not changed, only Lao Xia has become blonde and golden. Wei Li calmly analyzed.

"I mean, don't you think the system's package is the most important?" Wang Xiyi interrupted the conversation between the three.

[System Package: 1. A full set of knowledge of alchemy (improved version), a full set of knowledge of the use of leyline energy, body enhancement lv.1 (fist power 300kg), a letter of recommendation for the national alchemist assessment, a full set of rare-level clothing, basic ancient martial arts fighting skills, material perception ability, and a sense of three-dimensional space

A full set of alchemy knowledge (New Country Inheritance Edition), a full set of knowledge of the use of leyline energy, body enhancement lv.20 (the limit of human beings in this world, muscle fine-tuning, reaction speed of 0.03 seconds, strength 6700kg, non-full strength), resurrection once, a full set of Chinese super melee ancient martial arts, energy restraint knowledge (black technology, from the original world organization "Dream Builders Space Clinade Research Association"), Static Space (sound insulation, skills)

4. A full set of alchemy knowledge (the lost version of the ancient world of the new country, biased towards architecture and healing), a full set of energy use knowledge, a full set of energy use physique (non-human)]

"Choose two, you can tell the good and the bad depending on the richness, okay? The main and supporting teams in Steelforge are all main melee, and this body enhancement is just right. As she spoke, she clicked on option 2 on the light screen.

"Wait." Wei Li grabbed Li Ruoge's hand. "The use of leyline energy, with alchemy, make a head? Ruo Ge, are you going to grab the collar of the truth and ask him to change the rules or what? ”

The main power system of the steel world is traditional science and material transformation. Traditional science is about the same as the early twentieth century in the original world, with cars, trains, guns, and telephones, but if you want a computer or air conditioner, it's better to close your eyes and dream.

The transformation of matter is composed of alchemy and alchemy, both of which focus on different directions, but the essence is to transform one substance into another. The difference is that one is to use the energy of the ley veins and the other is to use the energy of the dragon veins. The general theorem is "equivalent exchange", and the principle of exchange is complex, not a simple principle of one gram for one gram. Therefore, it is called "equivalent exchange" rather than "equivalent exchange". The principle of transformation is to retransform or disassemble objects by refining arrays or some characters to guide energy. Because it's not the caster's own energy, there's no such thing as replenishing demons, as long as you're refining into a formation, you can use it infinitely. However, the output speed of the energy that each person can use is limited, and the matter that can be called is also limited, so it is not possible to make a palm-sized refining array that will sand everything within a kilometer of the power is not equal. Nor can one gram of stone be refined into a hundred grams. Of course, you can also draw a kilometer-long refining array or find a Philosopher's Stone to achieve this effect. The Philosopher's Stone is a solid that converts the soul into energy and compresses it, containing powerful energy. It is always regarded as an object increment, but it ignores the important function of exchanging souls due to the principle of equivalent exchange.

In the second plan, there is alchemy, but what is given is the knowledge of the use of the leylines. In short, useless. This is also the reason why Wei Li pulled Li Ruoge. If you can't use alchemy, what's the use of this? The transformation of matter is a feature of the power system of the steeled world. Even if this doesn't happen, what's the use of coming to the world of steeling?

"System, how long is it until the beginning of the story, that is, the protagonist Edward Eric becomes the national alchemist? What are our current ages? How long is it until the last National Alchemist Exam? Wang Xiyi asked all the important questions he could think of in one breath.

[You're now 15 years old, three years before the story begins.] The most recent National Alchemist Exam just ended this morning, and the next National Alchemist Exam will begin today next year. Therefore, you already have a full set of military alchemist credentials. The only difference with the authority of the National Alchemist is that you are not allowed to work on high-risk items such as synths, etc., without authorization. Your documents are in the left pocket of your respective coats. The cold electronic sound of the system echoed in the minds of the four.

"That is, we are three years older than the main character. Three years is enough time to establish a solid foundation. Xia Lin muttered to himself.

"Knock knock." Two short, powerful knocks came from the door of the small building.

"Hello, according to the second article of Chapter 63 of the Specific Alchemy Law of Central City, high-risk experiments are prohibited in Central City without the permission of the relevant departments. The military department has the right to search you and your home. Please open the door, the executor of this search is Yasren Ho. Signs of bioalchemical or similar alchemical use have appeared in your dwelling. Through the cat's eye on the oak door, Xia Lin and the four saw a pretty and immature blue-haired young face.
