The next day, Edward said goodbye to the group and boarded the train with his brother Alphonse to his hometown of Lysable.

The whining whistle sounded loudly on the platform, and the steel dragon with a sense of the times slowly drove away from the platform.

On the train, Edward leaned against the window, looking out of the window with a deep face.

"Brother, are you really going to dig up that pile of rubble?" Alphonse was worried about what his brother was about to do.

Beneath the ruins of their home lay memories they didn't want to recall, evidence of their ignorant sins, the remains of a mother made from the human body, and Alphonse didn't know if they had the courage to face it.

"Alphons, this is something we have to face, there is no solution to the problem by escaping, and ...... Even if it's even a little bit possible, I want to confirm what exactly we were refining back then. Edward said with a serious face.

People cannot be resurrected after death, and the refining of the human body has never been successful. Jiang Mu's words aroused deep doubts in Edward's heart, and he had to go back to investigate the matter clearly.

If it was confirmed that it was not the body of their mother, then the sins in their hearts would be much lessened.

"Hmm." Seeing Edward's resolute attitude, Alphonse also nodded, hoping that he would find an answer on this trip.

On the other side, Jiang Mu was not idle for a few days after Edward and the others left, but he basically couldn't be seen, because he had been buried in the National Central Library in Central City for the past few days. It was a large library with countless documents on display, and basically everything you needed could be found in the library.

Because of his status as a national alchemist, Jiang Mu can enter the National Central Library to consult materials without obstacles.

In the spacious library, rows of bookshelves about three meters high are neatly displayed like building blocks, like soldiers guarding the frontier, resolute and upright. Because there are so many bookshelves that light can't shine in, the shelves are a little gray between them, and the corridor is filled with the special smell of books, which makes you feel the history of this place.

These days, Jiang Mu has been studying materials here, and a mountain of books has been built in front of him.

Although Xiao Tian's progress in the steel refining world has been much faster under the acquiescence of the truth, according to the current progress, it will take a long time to fully penetrate this world. Taking advantage of this time, Jiang Mu planned to study the large-scale refining array in order to be able to play a role in the future.

Of course, the formation of the land refining array has become the first object of Jiang Mu's research.

The books in the National Central Library are very complete, based on the human body refining array, Jiang Mu quickly found out the principle and basic structure of the land refining array, and then carefully studied the land refining array again, and he found more subtle changes in it.

In the plot of Steelcast, there are a total of three super-large refining arrays, each of which is the size of the entire Amystolis border.

The first is the "Territorial Refining Array" secretly practiced by the villain Holmonx, who can refine all the civilians across the country into the Sage's Stone, and Holmonx opens the "Gate of the Earth, the Pupil of Heaven" and absorbs the "God" into his body.

The second is the "Reverse Refining Array" researched by the elder brother of Skar the Ishuvar based on alchemy and alchemy, which can make the alchemy seal invalid, and can also increase the alchemy effect of everyone.

The third is the "Rebellion Refining Array" laid out by Edward's father Hohenheim, which can return the souls of those who have been refined into the Philosopher's Stone back into the body.

In the final battle, this move almost gave the bottle villain a fatal blow, making the bottle villain unable to suppress the so-called "god" in the body in the final battle, thus blowing the horn of the turnaround.

And what Jiang Mu is working on now is also a super-large refining array.

Refining the descriptions of the large refining arrays in the library, combined with the wealth of knowledge from the truth side, he is researching how to achieve his desired goal on the basis of the "land refining array".

Snap and close the book in your hand.

Jiang Mu was silent for a while, then calmly picked up a pen and began to write. Drawing graphics on a blank piece of paper, as the tip of the pen wanders, the strokes are outlined together, the lines are constantly interlaced, the graphics become more and more complex, and then the large circle sets the small circle, and the flat figure actually begins to present a strange three-dimensional effect.

Hiss, the tip of the pen is dipped in ink, and the last stroke stops at the beginning.

That's it, you're done!

Jiang Mu looked at the refining array he designed with satisfaction, because the plane design could no longer accommodate the huge system parameters, so Jiang Mu had to find another way, and on this basis, he designed an almost three-dimensional refining array. Of course, the amount of work involved is quite huge, and if it weren't for his special status, ordinary people, even if they were a once-in-a-millennium alchemy genius, might not be able to complete this task.

"With this blueprint, we just have to wait for the last moment." Jiang Mu nodded lightly, and had a detailed plan for the future.

The final battle is the appointed day, when the next total solar eclipse occurs.

That was the crucial time to launch the super-large refining array, and at that time, whether it was the villain in the bottle or Hohenheim, they would take action.

There is still some time before the total solar eclipse, and this time is enough for him to go to the world to complete the layout of the refining array.

After carefully checking the lines of the refining array, and after confirming that there was no problem, Jiang Mu snapped his fingers out of thin air, and the scorching flames instantly burned the drawing into ashes.

"It's time to get moving." With a whisper in his mouth, Jiang Mu got up and stood up.

After leaving the National Central Library, Jiang Mu went to Mastan's office.

I've troubled Mastan enough of them in the past few days, and I should talk to them when I leave.

……

Leaving from Mastan's office, Jiang Mu went directly to the train station, and then bought a train ticket to the Eastern Capital, accompanied by the vibration of the steam locomotive, Jiang Mu began to march towards the Eastern Capital.

Distant Lissepur, the hometown of the Edward brothers.

On this day, the sky was overcast and there was a light drizzle in the sky.

Digging up the ruins of his hometown with his own hands, sorting out the bones that did not look like human bones at all, Edward looked at the skeleton, the whole person became silent, washed out the tufts of hair with mud with water, Edward looked at it blankly, and suddenly laughed.

"Brother......" Alphonse cried out worriedly.

"Now, Alphonse, Mommy's hair is brown, but this ...... It's black, and this skeleton is male, not a mother at all! ”

"It is true that people cannot be resurrected after death."

There was a self-deprecating tone in his voice, but Edward's spirit was refreshed, and he pointed to the bones on the ground and said to Alphons: "Since that day, these have been symbols of despair, but now they have become hope, Al, you can change back!" ”

"Well, brother!"

Alphonse nodded vigorously, although he may not have understood it as well as Edward, but his heart was also full of hope because of Edward's infection.
