Little black and white stepped over the door, they began to walk cautiously, because once the wrong step means that there is no return, when they cross the door, they are in front of a shining mountain, when they look back, the door behind them has disappeared, only a stone tablet is written, on which is written the sword mountain and the sea of fire.

When I was in the world, I always heard others say that they were willing to go up the knife mountain and go down to the sea of fire, but Xiao Hei Xiaobai was standing in front of the sword mountain and the sea of fire at the moment, a knife mountain with a cold light, this mountain is not too high, you can see the top of the mountain when you look up, but every place you reach the top of the mountain, there are two or three steel knives with the tips of the knives on the ground facing up in every inch of land.

Detours? Knife Mountain is surrounded by a sea of fire, and red and hot magma flows at the foot of the mountain, setting off waves of heat.

"Xiao Ling, I'll carry you up" Xiao Hei squatted down, picked up Xiao Bai and began to climb the knife mountain, he felt a pain in the soles of his feet after taking the first step, but he still took the second step, the strange thing is that as soon as he left the wound on the knife and foot healed quickly, so he will experience the pain of drilling his heart every step he takes, and he will not feel relaxed because of the numbness of the pain, but Xiao Hei still climbs step by step towards the mountain, sometimes he can't stand the pain and screams, Xiao Bai asked him to put himself down, she walked by herself, But Xiao Hei still refused to let Xiao Bai down, he knew how uncomfortable this pain was, he remembered what he had said to Master Xie the night before he died, and he also promised Master Xie that he would definitely take care of Xiao Ling.

The high level of pain made Xiao Hei's consciousness gradually blurred, his head was numb, and his sense of pain was not as sharp as before. In the end, he fell on the mountain of knives, his arms, thighs, chest, and face were all pierced by the knife, but he would not die, only feel pain.

I don't know how long I was in a coma, Xiao Hei felt that he was moving slowly, but he didn't feel pain, he opened his eyes with great effort, and saw that he was lying on Xiao Bai's back, her weak body was carrying Xiao Hei and crawling forward slowly, and countless wounds had been drawn on her body.

"Xiao Ling, I'll carry you" Xiao Hei's mouth said indistinct words, but Xiao Bai still persisted in climbing towards the top of the mountain, they were only a few meters away from the top of the mountain, there was no cold and shining knife, only a warm resting place.

"Let me come this time and you leave, you have a good rest" Xiaobai held a knife, blood flowed out of her hand, staining the knife and staining the land red, she pulled hard, and they took a small step forward, but more blood flowed from under her body, it was the knife under her body that was cutting her body.

Just a few meters, they don't know how long it took to climb, the top of the mountain is a flat land with an area of more than 20 square meters, in the middle is a warm pool, there is clear water in it, there is some food and two sets of clothes next to it, standing on the knife mountain and looking into the distance, there are eight such knife mountains, there is red magma between each one, there is nothing else in this world, this is the knife mountain and the sea of fire.

Xiao Hei Xiaobai was already very hungry, gobbling up the blood stains on her body with water after she was full, Xiao Bai's clothes had already been cut into strips of cloth, covered with blood, she wrapped her and Xiao Hei's old clothes around her feet and filled with a lot of dirt in the middle, so that the knife would not be inserted into the meat, she planned to carry Xiao Hei on her back and continue to move forward, but Xiao Hei was faster, he also did a good job of foot measures like Xiao Bai, picked up Xiao Bai and walked down the mountain.

It's easy to go up the mountain and it's hard to go down, it's even more difficult to come down from the knife mountain, those knives are not straight into the soil, but there is an angle, so Xiao Hei will slip when he steps on it, and if he can't walk a few steps, the strips of clothes and cloth will be cut, and his feet will be exposed on the knife, but Xiao Hei didn't show it, so he walked down the mountain with Xiao Bai in his arms.

When he came to the foot of the mountain, Xiao Hei was already in a painful cold sweat, but he still held back, standing on the edge of the sea of fire, waves of heat rushed to his face, and Xiao Bai's hair was permed and curled.

"Xiao Ling, I can't carry you this time, I can only swim over by yourself" Xiao Hei apologized to Xiao Bai apologetically, the sea of fire has no tools, and neither of them can go if they carry it. But Xiaobai didn't complain, and walked into the sea of fire first.

A burning sensation, a strong pain came from every inch of the skin on the body, it was more painful than on the knife mountain, the skin would not be burned, it would transmit pain all the time, they would not faint, they could only hold hands to encourage each other.

In this way, there was a painful wail from the empty sword mountain and sea of fire, I don't know how long it took, Xiao Hei Xiaobai finally turned over the nine knife mountains, nine seas of fire, and finally came to the door at the end, their clothes were messy, their hair was scattered, their eyes were red, they were laughing the moment they saw the door, and then they hugged each other and cried, I don't know how long it took, they pushed the door open, and started another test.

When they pushed the door open, they felt it dark, and they both fainted.

Xiao Hei felt as if he was in the water, his body was wrapped in something, he felt very comfortable, he felt that he was sinking, his body was very tired, he didn't want to move or struggle, but soon his mind flashed Xiao Bai's cute face, and he opened his eyes all of a sudden. He is indeed in the water, his back is the dark bottom, no one knows what is in it, Xiao Hei is lying in the water and floating at will, he raised his head and looked around, and did not find Xiao Bai's figure, he shouted loudly, but there was no sound around, he held his breath and dived into the water and still found nothing, he was desperate, he looked at the huge bloodshot eyes in the sky, those eyes were also looking at him, Xiao Hei found these eyes when he woke up, but he was busy looking for Xiao Bai, didn't care about these eyes at all, but Xiaobai was gone, and he lay down quietly and looked at his eyes.

Xiaobai woke up on a flat ground, there were no stones or trees around, nothing, only a red sky, but it was too high and too high, Xiaobai opened her mouth and wanted to shout, but she opened her mouth and found that she couldn't make any sound, the surroundings were also quiet, all she could hear was her own heartbeat, knock, all at once, it made people feel depressed, Xiaobai frantically slapped the ground with his hand, even if it could make a little sound, but there was still no sound, Xiao Hei was gone, Now she is the only one in this place, and she faces the world by herself.

She didn't know where to go, so she chose a random direction and started moving, hoping to meet Xiao Hei in front of her and see Xiao Hei waving to her. Xiao Hei was floating in the water, and he felt that his eyes were staring at him no matter where he was drifting. He also gave up the struggle, just drift like this, he hoped to meet Xiaobai ahead.

They are each other's dependents and are the only relatives in this world. Now that they're separated, they don't know if each other still exists in this world, and they're both looking for each other. In this way, Xiao Bai was walking in one direction, there was not a trace of sound around, and she couldn't say any words, Xiao Hei floated in the water, looking at the eyes in the sky.

I don't know how long it has been, they have blurred the time, there is no day or night here, they don't feel tired, they don't need to eat and drink, they only have one thought left in their hearts, and that is to find each other.

Finally, Xiao Bai saw a piece of the sea, this sea is so vast and boundless, she jumped into the water and swam along the coastline, Xiao Hei finally touched the land, he lay still, he knew that Xiao Bai would come to him, this was their agreement when they were children.

"If I can't find you one day, you will wait for me at the place where the water and land meet, and I will go to find you" The little black head remembered Xiaobai's words, and he just lay still, looking at the eyes in the sky, and those eyes seemed to have found something, and there were more bloodshots. I don't know how long it took, Xiaobai finally saw a trace of abnormality in the sky, a red cloud floating on the sea, which had never happened before, she sped up and swam towards the cloud, and when she got closer, she found that there was a pair of huge bloodshot eyes in the cloud, it was staring at her deadly, and cracks had begun to appear on the eyes, dripping dark red blood.

She slowly approached her eyes, and found that there was a person lying on the sea below where her eyes were looking, and the distance was too far to recognize, but Xiao Bai still swam towards that person, and when she got closer, she found that it was Xiao Hei, Xiao Bai was ecstatic, swam up and hugged Xiao Hei, she wanted to say something, but she couldn't make any sound, and Xiao Hei was still staring at the eyes in the sky, and did not give her any response.

In this way, I don't know how long it took, those eyes finally couldn't support it, shattered into pieces and disappeared between heaven and earth, Xiao Hei's eyes also regathered, and found Xiao Bai lying beside him, and woke her up softly.

Xiao Bai woke up and found that the eyes were gone, Xiao Hei also returned to normal, wanted to ask Xiao Hei what was going on, and found that she could speak, so from this time on, she began to have a more characteristic of chatting, she was afraid that if she didn't say it at this time, she didn't know when she couldn't speak again in the future.

They climbed ashore and found two impermanences flying down from the sky and falling in front of them. He said congratulations and congratulations, and then led them out of the place one by one. Soon they arrived at the same mansion where they had been when they first came to the underworld, and the black and white impermanence continued their usual work, as if they had only been away for a long time.

"How long have we been in there," Xiao Hei asked, the black impermanence beside him.

"It's only been more than four hundred years," the black impermanence glanced at Xiao Hei and replied coldly.

"What about Xie Bi'an and Fan Wusheng?" Xiaobai asked, she wanted revenge, and the torture for so many years seemed like yesterday.

"Presumptuous, the names of Lord Xie and Master Fan are also what you can call casually" The black impermanence made a straight face and wanted to reprimand Xiao Bai, but was interrupted by someone talking.

"The two of them are our descendants, it doesn't matter what they are called, you go down and get busy" Bai Wuchang waved his hand and let the two black and white impermanence leave, and walked to the backyard with Xiao Hei Xiaobai.

"Why are you torturing the two of us like that" Xiao Hei began, and he asked very calmly and calmly.

"What that eye is, you know? That's the anger of the two of you, if you don't wear out the anger of the two of you, you can't do the work of black and white impermanence" Bai Wuchang said as he pushed open the door of a room, which was full of torture instruments, from broadswords to iron sticks, from lightning strikes to water showers, where all the torture instruments in the world were gathered, and in the center of the room was a man with his hands, feet, and head bound in chains, his body was covered with scars, his hair was scattered, his lips were chapped, and he was muttering something to himself.

"This is the biggest murderer who killed you, Fan Wusu and I tried our best, and even pulled down our old face to plead with the king of Hades before agreeing to hand it over to us to deal with, now you use the tools here to take revenge, and after the revenge is over, the next room will find us" Bai Wuchang left after speaking, and closed the door of the house when he left. He had just left when he heard a heart-rending cry coming from inside the room. Bai Wuchang shook his head helplessly, then pushed open the door of the room next to him and walked in.

Soon after, the door of the torture room opened from the inside, and Xiao Hei and Xiao Bai walked out with a smile on his face, blood flowed from the corner of his mouth, and the moment they closed the door, only a white skeleton was left in the middle of the room.

Little Black and White pushed open the door next to him, and what came into his eyes was Black and White Impermanence drinking tea with a teacup, they just knelt down and kowtowed three times to Black and White Impermanence, and then Black and White Impermanence didn't say anything, and handed them over to the two Black and White Impermanence.

Later, they learned how to use black and white impermanence, and were taken by other impermanence to familiarize themselves with the operation of the underworld and some institutions, such as Meng Po Tang, Lechuan River, Wangxiangtai, Ghost Gate Pass, etc.

Later, Black and White Impermanence called them and said that they needed help with something.

"Fan Wusu and I hope that you will join the work of black and white impermanence, and inherit the position of the two of us when the time comes, but the two of you have no performance, so Fan Wusu and I will pull down our faces and find a job for you to patrol the yang world, and you two will cooperate well with others and strive to become positive as soon as possible" Bai Wuchang took out a letter and asked Xiao Hei Xiaobai to listen to others and not be mischievous. Black impermanence doesn't say anything, Xiao Hei Xiaobai is also used to it, but Xiao Hei has a mustard in his heart, he doesn't want to believe in people, he is more willing to believe in ghosts in comparison.

In this way, they were sent to the yang world by Bai Wuchang that night, and before they could be introduced to Qin Feng, Bai Wuchang ran to collect the Yin Spirit, and Xiao Hei Xiaobai remembered his words, and An An lined up separately.

After listening to what Xiao Hei said, Qin Feng asked him to recuperate, and then Xiao Lou lay on the sofa chair and enjoyed life, he wanted to know the story of Xiao Hei and Xiao Bai, which was convenient for him to better integrate with Xiao Hei and Xiao Bai, they should be a family.

Looking at Xiaobai who is busy in the store, although she usually talks a lot and acts crazy, but she has been suppressed for too long, she just wants to vent it, in fact, there is nothing bad about this kind of character, just treat her as her own sister, although her age can be regarded as her ancestor.
