After Maxing out all Classes

> 

Embarrassed, Kelly said, “it's just that if it's an ordinary blacksmith, I can't teach them well, because to make steel, you need to know how to use and manipulate the element.
An ordinary blacksmith can't control the elements, and only know the basic magic of the earth system.”

“Not really.” Robb waved his hand and took something from the air.
A square iron box flew into his hand.

Kelly recognized it at a glance.
It was a magic container.

Robb smiled and said, “this magic container is specially used to contain the element of carbon.
In the future, my craftsmen don't need to know magic.
They just need to extract magic from someone who knows alchemy in advance and put the element into this box.
When the craftsmen make steel, they just need to mix the element in this box into iron in a certain proportion.”

“Oh,” Kelly said, “that's a good idea.
But in this way, the division of labor is very thin.
The production of a piece of steel can only be handled by one alchemist, but now we need to send out an alchemist, a craftsman, and even a magic container.
Won’t it become very inefficient?”

Robb laughed and said, “if only a small piece of steel is produced, the division of labor will be more and more inefficient.
But if we produce a large amount of steel, the division of labor will be more efficient.”

Kelly was confused and didn't understand what was going on, but he didn't complain to Robb.
He just listened to him.
The more people knew, the more they knew not to casually question something they didn't understand.
The more they saw it clearly, the more stupid they were to spurt out their own wisdom, and the result would be that they were very “wise”.

Robb said, “anyway, I have arranged the first group of students for you.
Go to the school to find the principal.
He will arrange a dormitory for you.”

Kelly bowed and was about to leave.

But Robb suddenly waved at him again with a mysterious smile on his face.
“I heard that you tried to add something else to the steel, but you blew yourself up.”

With an embarrassed smile on his face, Kelly said, “I'm sorry.
I was thick-skinned, but as a result…”

“Haha, don't be embarrassed.” Robb said, “I think being thick-skinned is very good, very good.
Your idea is correct, but you just added something wrong.
Do you want to know what else in the steel can make it more corrosive, harder, and even more awesome?”

Hearing this, Kelly became excited.
“It turns out that Godfather has been studying for a long time.
Please give me some advice.”

Robb said mysteriously, “what I'm going to tell you is the technique that only gods can master.
But if I tell you everything, gods will blame me, so I can only tell you a little.
You have to test the specific thing by yourself.”

Kelly hurriedly said, “as long as you can guide me the way, I can save a lot of time.”

“Okay, listen carefully.” Robb chuckled and said, “in relation to ores, there are not only copper, iron, silver, gold.
There are also many magical and unknown metal elements.”

Kelly nodded in a hurry.
“I know that.
There are also mithril, thorium, Arcanite and so on.
But those things are very rare and difficult to get.”

“Let's not talk about those difficult things.” Robb whispered “I've told you that it's easy to get them, such as, for example, chromium, molybdenum, titanium, manganese, and so on.
Of course, I know you haven't heard of these things.
Although I know them, I can't teach you too much, in case the gods blame me for exposing too much.
Just remember what I just said, and then use your alchemy to look for them in all kinds of ores.
As long as you find them, add them into the steel, and mix them with the correct proportion! “
