The sun in the Ghost Realm was still dim, there was no bright sunlight, and there was no blazing temperature. But in the extreme east of the ghost realm, there is a hot zone. The heat in this area is not brought about by the sun in the sky, but by the fire that lies beneath the ground. But no one knows where the fire comes from.

"Really, it is said to be the easternmost part of the Ghost Domain, this easternmost is so big, where is it?" Bai Ye carried the heavy Seven Deadly Sins on his back and walked alone in the Far East. Her long pale hair was soaked with sweat, and the placket of her clothes was completely soaked and clinging to her body. With his feet on the hot ground, he "paced" forward step by step, and his back was also pressed against the seven deadly sins.

This is not a desert because there are water sources everywhere. But the desert-like temperature makes the water boiling hot.

Before this, Bai Ye also hesitated for a long time. Because he only knows how to be strong, but he doesn't know how to be strong. After that, he suddenly remembered that someone had recommended him to learn blacksmithing. That person was a teacher at his Black Emperor Academy, Tian Li.

Tian Li once said that if he wanted to learn the art of forging, he could go to the easternmost part of the ghost domain to find Tian Li's teacher, and told Tian Li that his teacher was recommended by Tian Li. After thinking about it in a variety of ways, Bai Ye felt that it was feasible.

Pure revenge only requires great strength. But what about after revenge? There is still a long way to go after revenge, but I can't be satisfied with the pleasure of revenge and stop there. He still has relatives to find, friends to protect, and a future life, all of which can be satisfied by more than just strong strength.

No matter how strong a person's strength is, he can't withstand thousands of troops. So he has to have a strong force. And becoming a good blacksmith is a great way to have power.

It's just that...... This easternmost side is really too big, God knows where Tian Li's master is?

Another day passed...... White Night found nothing.

Another three days passed...... Still nothing was found.

Another five days passed...... Still nothing was found.

After another eighteen days, Bai Ye finally found a small house. Finally, I no longer have to endure the days of drinking hot water every day to satisfy my hunger. It's just that...... The house is also a little too small.

It is no more than two meters tall and just over a meter wide. It's completely metallic, but it's also rusty. But it doesn't matter, the important thing is that the size of the house is simply impossible to live in, let alone forge. No, it's not a house anymore, it's just a thatched house. But there is only this one house within a radius of dozens of miles. No matter what, just open the door, maybe there is some special mystery inside.

"Anyone? I was recommended by Tian Li to learn blacksmithing. Bai Ye knocked on the door and shouted at the door. But no one answered.

"Hey~~~There are ~~~ people~~~~~?"

Still no one answered.

"Hey~~~~~~~~~~. ”

Still no one answered.

"It looks like there's no one left, so it shouldn't be here. Bai Ye muttered to himself, dispelling the idea that this was the destination, and planned to continue looking.

"Hey, stinky boy, what are you screaming at a toilet?" a white-haired old man appeared behind Bai Ye at some point.

The old man's white hair was somewhat similar to the color of Bai Ye's hair, but the old man's hair was less than a centimeter long, while the one in the middle of the night was shoulder-length hair. The old man was short in stature, only reaching the neck of the white night. The back is slightly bent but not hunched. His complexion is ruddy, full of energy, and he has good strength, which can be seen from his ability to appear quietly behind Bai Ye and be surrounded without concealment.

"This ...... Is it really a latrine?" Bai Ye was a little speechless, he seemed to have been turning around the latrine for a long time just now, and shouted twice. I don't know if it was all seen by this old man. Shame on you.

"Do you think that the eyes are not good for the nose?" the old man pouted.

In fact, Bai Ye has been walking in this place for more than 20 days, asking about the smell of sand and earth every day, and his nose is really not very good. "I'm sorry, kid was stupid. But I want to ask the old-timers, do you know Tian Li?" Bai Ye didn't care if he had lost someone just now, or if it was important to find his destination, so he asked.

"What? You know my unruly apprentice?"

"You are Teacher Tian Li's master?"

"Teacher, oh, by the way, he is now working as a logistics officer at the Black Emperor Academy, and you are a student of the Black Emperor?" the old man asked.

"Yes, the kid came to learn from you at the recommendation of Teacher Tian Li at the Black Emperor Academy. ”

"Oh. The old man nodded, and then asked, "What do you want to learn?"

"What is there to learn. ”

"You kid has a big appetite, be careful and don't chew too much, but I see that you still know some etiquette, and it doesn't hurt to teach you something. Come with me. With that, the old man opened the door of the "latrine" and walked inside.

“...... Senior, isn't this a latrine?" asked Bai Ye cautiously.

"Are you really stupid or stupid? There is no one in this radius of dozens of miles, what are you doing building a latrine?" the old iron head pursed his lips again and continued, "This is the entrance to the Iron Castle. By the way, don't call me an old-timer in the future, it sounds awkward. My name is Tie Qiusheng, you can just call me Old Tietou. ”

"Iron Castle?" Bai Ye was very unfamiliar with the word. Bai Ye was familiar with all the books in the Bai family, and he had never heard of such a place as the Ghost Domain and the Iron Castle.

"That's where I live, and that's where I strike iron. The old iron head explained.

Entering from the entrance is a flight of stairs that descend downward. The stairs are not long, but they are steep. It's also thanks to the old iron head that he can walk here freely at such an old age. If you go down the stairs to the bottom, you will see a door. Inside the door, there is a spacious room. In the center of the room is a huge melting pot. Around the big room, there are small doors, which are estimated to be some small rooms, including where the old iron head lives.

"Well, that melting pot is my forging furnace. The fire inside comes from the fire beneath the ground, and as long as the fire does not disappear, the fire here will never be extinguished. And the temperature is many times higher than that of ordinary flames. That's why I built the Iron Castle here. The old iron man introduced his forge and looked at it affectionately, like an infatuated man looking at his lover.

"Is the earth fire? does the iron senior know where this earth fire came from?" Bai Ye has no interest in the old iron head's habits, but is quite interested in this earth fire.

"How do I know, all I know is that this earth fire works well, and that's it. The old iron man shrugged.

"......" Bai Ye was speechless.

"Alright, don't you want to learn from me? I have nothing to teach you, I can only strike iron, and I can only teach you to strike iron. Come here, I'll see how talented you are first" As he spoke, the old iron head pulled Bai Ye to his side, and pressed a big hand on Bai Ye's head.

"Well...... Kindness...... The soul strength is good, Eun...... The mental power is also good, well...... ...... old iron head pressed Bai Ye's head, muttered to himself, first nodded appreciatively, and then shook his head, "The attribute is perfect, the strength is not too prominent, and the speed is not very good, which is not very beneficial to striking iron." ”

"Boy, you are a cultivator, what is your spirit?" the old iron head took his hand off Bai Ye's head and asked. Although the strength of the old iron head is unfathomable, the scope of exploration is also limited. Or maybe it's found out but you don't know it. After all, there are so many cultivation methods that exist in this world, and almost no one can write down all of them.

"Black Hell Soul Flame. White Night replied.

"Black Prison Soul Flame? People from the Bai family?" Although the old iron head was asking, there was no doubt on his face, obviously not too surprised by the five major families.

"Don't hide it from your predecessors, the kid is the third son of the Bai family, Bai Ye. Bai Ye replied respectfully.

"Black Prison Sacrifice Soul Flame ......" Old Iron Head No. 4 ignored which family he belonged to, and thought about the information about the Black Prison Sacrifice Soul Flame.

"Black Hell Sacrifice Soul Flame, no high temperature, no explosive power, strong corrosiveness, penetration and concealment. That's right. Finally, the old iron head remembered the information about the Black Prison Sacrifice Soul Flame.

"Iron seniors are well-informed, and that's exactly what happened. Bai Ye still maintained a respectful posture, and by the way, he also patted a small ass. Of course, the purpose is naturally to let the old iron head accept him.

"Don't pat me on the back, you can go back. "The old iron head doesn't eat the white night.

"How to go back?" Bai Ye couldn't help but ask. That's it? Haven't started to go back to yourself? What's going on?

"How you came to go back. I'm not going to take you as an apprentice. The old iron head said ruthlessly.

"Can you tell the juniors why?"

"You're not fit for forging. The old iron head also changed his tone, and no longer said that forging was iron.

"I'm not suitable for forging?" Bai Ye was puzzled by the old iron man's answer.

"Forging requires the power and speed of swinging a hammer, and your attributes are perfect, which dooms you to not have particularly strong strength and speed. Forging also requires a high-temperature flame, and your spirit is a low-temperature flame. Forging also requires strong soul power and spiritual power, and you can meet the requirements for these two points. ”

"Can't the high-temperature flame borrow other flames? ”

"Do you think that after you get used to your own spirit, you will still be able to control the high-temperature flames? unless you give up cultivation, but then your soul power and spiritual power will not be able to keep up. ”

The old iron head's words completely dispelled Bai Ye's thoughts. Talent, he has no talent for forging. He could not learn to black, and in order to achieve his goal, he had to take a different path, and the other paths were destined to be more difficult. But there is no way, talent determines that he can't take the road of forging.

"Alright then, bother, senior. The boy took his leave. Bai Ye bowed like an old iron head in a little frustration, took up the seven deadly sins, and turned around to leave.

"Wait. Just as Bai Ye was about to leave, the old iron head suddenly stopped Bai Ye.

"Is there anything else going on with the Iron Senpai?"

"Actually, you have another choice. Or rather, another opportunity. The old iron head said unhurriedly.
