After Li Ling was brought back to the barracks, he simply settled there, fortunately, he could collect those black energy bodies on the battlefield at will. His mental power grew rapidly, and he stopped thinking about other things.

The continuous sound coming from the courtyard next door all day long caused him a great deal of confusion, and he did not know who lived there, let alone where the sound came from.

Finally, one day, he came to the door to find out, but found that the person who opened the door for him was actually a very short old man, with tense muscles and sweat.

"Is there anything you can do?" The old man asked, puzzled, and stood on the threshold with his feet in a very impatient look.

"I'm just here to see what you're doing here, I live next door to you, and I just hear ping-pong noise here every day, so." Li Ling said with some embarrassment, he actually came here because of curiosity.

"I'm sorry, I'm a blacksmith, please forgive me if I disturb your goodness!"

"Can I go inside and have a look?". Along the crack in the door, Li Ling saw the weapons placed on the weapon rack, row by row, flashing with the same light, like a beast that could be selected and devoured at any time.

"Okay!".

The old man hesitated for a moment but let him in. As soon as he arrived in the courtyard, Li Ling even appreciated the compelling momentum of the weapons. The cold light was a little bit, and none of the weapons revealed a cold and arrogant killing intent. It looks so unruly.

There was a huge stove in the middle of the courtyard, and there was a dark black flame in it, and as soon as he happened to be next to it, Li Ling felt a compelling heat. These flames seemed to be even hotter than those absorbed by Zhu Rongyan.

"Can I take a tour of your masterpiece?". Li Ling had heard from the captain of the crow soldiers, this old man was very strange, he didn't stay with other blacksmiths, and he didn't need the help of other people, so he spent all day alone in the yard tinkering with weapons.

These crow soldiers only tolerate him because of the old man's good craftsmanship. If nothing else, the scrap he threw away was no worse than the weapons made by the masters in the barracks. Until now, the captain was still wielding a large sword that the old man had discarded two years ago.

"Old man, your surname!" Li Ling asked quietly. He had heard that this old man was even more mysterious than his origins, and no one knew who he was. When he came to the barracks, he was seriously wounded.

He made a special observation and found that the old man was full of new wounds and long marks, and it seemed that the old man was also a person with a story.

"I don't know. I forgot, I really don't remember what I used to do!". The old man smiled wistfully, and was about to throw a large blue nameless metal furnace into the furnace.

Li Ling hurriedly came over to help, seeing that he made a complicated handprint, a strange energy suddenly filled the small courtyard, and a strange feeling suddenly emerged from his heart, the old man's refining method seemed to be quite clever, at least much better than the industrial model adopted by the Federation.

This attracted Li Ling's attention, and he found that the old man's gestures changed very quickly, sometimes he could change more than a dozen times in an instant, and his head was a little big, but there were very few gestures that could be remembered.

"It's really strange, is this old man still a hidden master?" Li Ling's heart moved, and he couldn't remember those complicated and changeable gestures anymore.

"Really, it's still a little lacking in heat, I'll give you this defective product!". Finally, the old man came and took out a blue sword from the stove.

Li Ling wanted to help, but when he saw the old man gesturing over and over again, he retreated a little, and his rash actions might only have the opposite effect.

Li Ling laughed helplessly, the captain had told him that as long as he could get a little bit of something back from the old madman, he would be rewarded, even if it was a piece of scrap metal.

"Buzz". At this moment, all the weapons in the courtyard began to shake, and even a few short daggers were shaken off the weapon racks.

Li Ling immediately understood, this time he had gotten a treasure, just imagine, a long sword that could resonate with other weapons. It's also a divine weapon. It's a bit big for me.

He once again looked at the old man's scars, and decided to give him a clean body, anyway, there were medicinal herbs in his ability space, and with his own skills, he was not able to catch it.

When Li Ling told the old man his thoughts, he thought for a moment and finally nodded in agreement, not that he was arrogant, nor that he refused to go to the doctor, but that he didn't believe that these quacks in the barracks could cure his illness. It was only because Li Ling was famous that he was determined to give it a try.

In the next few days, Li Ling had to run to the old man every day, and because of his medicine at any cost, the old man's body finally gradually improved. But he still insisted on letting the old man take a medicinal bath every day, and he had to take a large dose of herbs, Li Ling had already seen that the old man was an extraordinary person, and he couldn't treat the other party as an ordinary person.

Seeing that Li Ling and the old man were familiar, the captain paid attention to him, and wanted him to ask the other party for a few decent weapons, but he refused directly.

The captain shook his head and left Li Ling's small courtyard, saying in his heart that he had wanted to see the true craftsmanship of the old madman in this life.

After the two got acquainted with each other, the old man was even more shy of Li Ling when refining weapons, and sometimes when he came to help, the old man deliberately introduced him to himself. When refining weapons, the speed of gesture transformation also slowed down.

The opportunity is rare, Li Ling also memorized these steps attentively, and constantly rehearsed various handprints in his mind, breaking down each gesture little by little, and trying to find their specific functions.

"Do you have any medicine that can help people recover their memories? I really want to understand what kind of being I am!" After the old man's injuries were all healed, he asked Li Ling, every time he thought that other people had names and a past engraved in his memory, the old man felt that these people were so happy, at least they knew who they were.

Li Ling couldn't help but shake his head, it was too difficult to awaken a person's memory with a little herb. Perhaps it can only be done by using the high-tech means of the federation to activate the brain cells of patients one by one.

Although he already had the answer in his heart, the old man was still very sad after hearing the other party's refusal, maybe this is fate. He thought faintly.

"Don't be too pessimistic, I'll try my best, maybe I can?". Li Ling comforted
