Nangong Du first bought a horse in Xuzhou City, and then went all the way to the southwest. He rode his horse for a long time, got off the official road, and walked on a forest path, the mountain road was rugged and difficult, and he also wanted the horse to rest, so he led the horse all the way to let it eat some grass, while walking slowly.

He walked among the mountains and forests dappled with light and shadow, and suddenly felt that there seemed to be a figure flashing behind him, and when he looked back, there was no one there. Nangong Du was suspicious in his heart, and always felt that someone was following him, but looking around, the green trees were standing, the grass and trees were deep, and occasionally birds flew by, trembling single branches and leaves, where was there half a figure. Nangong Du stopped, tied the horse aside, and sat down under a tree, half-squinting, pretending to be asleep, and sure enough, after a while, he felt that someone was on the tree above him. He quietly held the mist knife, ready to go, suddenly, there was a faint fragrance from his nose, his heart moved, he opened his eyes and looked up, only to see a woman in emerald green clothes sitting on the branch above his head, she was also looking down at him, the waterfall-like black hair hung down from both sides, and the hair was blowing on her fair face with the wind, and the feminine appearance was seductive.

Nangong Duxi said: "Skylark, why are you here?"

"I've been waiting for you outside Xuzhou City for three days, and this morning I saw you riding out of the city gate, so I followed." The lark leaped from under the tree, its coat flying. Today, she is dressed like a small jasper in Xuzhou City, with a colorful hosta in her hair bun, and a cyan thin skirt.

Nangong Du looked at the lark who was like the two before, and thought: The woman is really strange, and the change of dress is as if the whole person has changed. Seeing him in a daze, the lark tugged at his sleeve and said, "Hey? What's wrong with you?" Nangong Du immediately came back to his senses and said, "What did you just say?" Wait for me for three days, why wait for me?" The lark said seriously: "I sent you to the place drawn on your map, but it is inconvenient to stay, so I don't know if your poison has been smelted?" I just want to wait here and see, if you smelt the poison, you will always have to go down the mountain. Nangong Du said again: "Oh...... I was about to thank you for sending me there. The lark smiled heartily, patted him on the shoulder, and said, "You're welcome, I also want to thank you!" If it weren't for you, how could I have made up my mind to leave Chidorka?" Hearing this, Nangong Du was shocked and was about to ask, but the lark seemed to be trying to block his mouth, so he first said counterproductively: "By the way, where are you going?" Nangong Du didn't want to hide it from her, and truthfully said that he was going to Yunnan Yigu, wanting to find out what was going on with the tragedy of Nangong's family back then, but he didn't say anything about Iris and Qi Xiaowu. Since the lark already knew his background, she naturally understood his approach, but she seemed to be worried and hesitated: "I know that your martial arts are good, but legend has it that there are Yin soldiers guarding the valley, and ordinary people can compete with it." Nangong Du laughed a few times and said: "I, Nangong Du, never believe in these ghosts and gods, so there must be something strange about it, even if it is not for my family affairs, I have to go and see it." The lark pursed his lips and stopped persuading. The two were silent for a moment, and the atmosphere was suddenly a little awkward. Nangong Du has a life-saving grace for the lark, and the lark sent him to Weng Shen Doctor, which can be regarded as a sense of help, and more importantly, Nangong Du didn't know that the first two days of getting along had unconsciously ignited the lark's cold heart, she couldn't sleep peacefully for several nights, repeatedly thought about the meaning of her life, and decided to change her established fate. Therefore, Nangong Du is like a guide who suddenly appears on the way to her, reassuring her and trusting her. She waited for him here for three days, as if to meet him in her new face and surprise him. But what about after the meeting? There was no reason for her to stay with him, should she turn around and go back? She didn't speak, waiting for Nangong Du to give her a choice. Nangong Du didn't know what she was thinking, but he felt that the lark had been waiting for him for a long time, and if he saw this side, he would ask her to go back, which seemed too meaningful. So he said: "If you have nothing to do, you can go to Yunnan with me, but I am afraid that the valley is in danger, so don't follow me into the valley." Do you think so? The lark smiled and nodded.

On the way, the lark chatted with Nangong Du about which masters she knew had been folded in the valley, and there were not a few famous ones, such as Shangguan Yinji of the 'Baili Divine Whip', Hu Yifei of the 'Thousand Leaf Knife', and Yu Qiantai of the 'Lei Yin Palm'...... There is no return, there have been so many masters in the valley of treachery, saying that the place of Yin is not simple, Nangong Du went deep into the valley this time, and he didn't know if he could come out alive. He was originally alone, ready to die at any time, but now when he thought of Qi Xiaowu, he was no longer as free and easy as before. He sighed in his heart: If I die, Xiaowu will probably wait for me all the time, unless...... She knew that I had killed her father, and she would not wait for me any longer. He suddenly saw the lark beside him, and said, "Skylark, I have something I want you to help with." If I go to the Valley this time, I ...... If I can't come out, I want you to go to Doctor Weng again and help me bring a message to someone. The lark glanced at him and said, "Before we reach the valley of treachery, let's say these are unlucky!" She said that she would no longer pay attention to Nangong Du and walked forward.

Nangong Du only has one horse, men and women are different, can not always ride with the lark, so, let the horse to the lark, he led the horse to walk, even if the lark does not ride, he no longer rides, the two of them walked like this, suddenly the trip was much slower, Nangong Du originally planned to go from Xuzhou to Wumeng in five days, and then use three days to enter Qujing City, Yunnan. Now it seems that the time to Wumeng alone is probably going to double, as long as you get to Wumeng, you can buy another horse, and then you can only run to Qujing non-stop.

Along the way, the lark seems to be quite happy, even if he passes through a small town, he has to have a good time. Nangong Du can only accompany her all the way to the mountains and rivers. The two walked to the outside of Wumeng City, in the suburbs, suddenly saw a cemetery, the tombstones were neatly arranged, and the handwriting on the stele was also the same, it seemed to be the ancestral tomb of a certain family, many people who were not wealthy could not afford to build an ancestral hall, so they buried their own family members in one place, and made the ancestral hall. At this time, the two of them were able to look at the gate of Wumeng from afar, only to see a mourning team coming towards this cemetery, about a dozen people, wearing linen and filial piety, and mourning shook the sky.

The lark looked at the mourning team, swept away the happy expression of the past few days, and suddenly said melancholy: "Alas...... I, a nameless and nameless person, will die in the future, and I am afraid that there will not be anyone to bury me. Nangong Du also knew that she had always been obsessed with her name, and she didn't know how to persuade her. The lark suddenly laughed again: "Why don't you give me your last name?" Nangong Skylark, it sounds pretty good. Nangong Du was stunned, since ancient times, women have taken their husband's surname, and the lark is not his wife, how can she casually follow his surname. Embarrassed, Skylark chuckled and said, "I'm kidding." Then he pointed to the mourning team and said, "They are coming, the dead are the greatest, let's get aside and let them go first." Nangong Du nodded, and the two of them got off the horse, led the horse slowly on the side of the road, and waited for the mourning team to pass.

The mourning team slowly approached, the two sides staggered by, Nangong Du and Skylark couldn't help but look at this group of people, only to see that they were men and women, all of them were in their twenties and thirties, and their bodies were also well-proportioned and strong, but among the mourners, there were no old people or children......
