When Nangong Du woke up again, the first thing he saw was a lark, he was a little surprised, but not very surprised.

However, the fact that he is still alive proves that the lark is no longer his enemy. When the lark saw him wake up, he immediately asked with concern, "Are you awake?" How does it feel? Nangong Du felt that his back was cold and wet, as if he had put on some medicine, so he reached out and touched it, and sure enough, a thick layer of straw slurry was applied to his back, and he suddenly turned pale What was going on, and he hugged his fist to the lark and said, "Thank you!" The lark saw that he only said a word

"Thank you" didn't seem to intend to say anything more, and said a little embarrassedly: "You're welcome." Look at your injuries...... It's not like the poison in the Central Plains, it can't detoxify you, so you can only use some medicine to control it a little first. The lark paused, seemed to hesitate, but continued: "Although I don't know what kind of poison this is, but the golden-robed people I saw that day poisoned you, they may ...... It is from the valley of Yunnan. If my speculation is correct, then the poison in you is the Yunnan Gu poison. So, you ...... I still have to get out of here early and go to the doctor. Nangong Du didn't expect the lark to tell him this so frankly, so he also let down his guard and asked, "Yunnan Strange Valley?" I haven't heard of it, how much do you know? The lark's eyes widened, and he said incredulously: "You don't know Yunnan Strange Valley? Then do you know the Feng Yu brothers and sisters? Nangong Du shook her head, the lark hesitated for a long time this time, and it wasn't until Nangong Du urged her that she bit her lip and said, "I also listened to these things from my classmates, and they may not be true, so I will tell you about them." Twenty years ago, there was a pair of brothers and sisters from Yunnan Yigu, the elder brother was called Feng Yubai, and the younger sister was called Feng Yuling, they were good at using Gu poison, it seemed that they came to the Central Plains to find a treasure knife, it is said that the treasure knife is the key to open a treasure. But the owner of the treasure knife is quite famous in the rivers and lakes, and his martial arts are not weak, and their brothers and sisters are not opponents at all, so they promised a lot of money to the Thousand Bird Pavilion, so that the top killer at that time, the ghost car, personally carried out this task, and the ghost car really lived up to their expectations and killed the owner of the treasure knife. This incident was also a major event that shocked the martial arts back then, and then ......" The lark said this, his voice became weaker, and he secretly glanced at Nangong Du a few times, as if he was watching his changes.

But Nangong Du was calmer than she imagined. Nangong Du didn't even expect his external performance to be so calm, maybe it was because he had already stabbed the ghost car, and the most painful hatred in his heart had dissipated, and now he could calm down and accept this matter.

He said coldly: "Then, the ghost car killed my parents, snatched our family's iris knife, and handed it over to the Feng Yu brothers and sisters, and then successfully withdrew from the Thousand Bird Pavilion, becoming an example for you juniors to worship?" The lark didn't care about the sarcasm in his words, but continued: "No, it's not that simple. Soon after the ghost car withdrew from the organization, rumors spread about the Yin-Yang Tower, and it was said that the iris knife was the key to open the Yin-Yang Tower. There is an extraordinary treasure in the Yin Yang Tower, and it is said that this treasure is not a gold or silver treasure, but a divine object that can reach the heavens and the earth, and even the emperor Lao'er is rare. Since then, batch after batch of good people from the rivers and lakes have gone to Yunnan Yigu to look for the Yin-Yang Tower, but no one has returned. Because legend has it that there are Yin soldiers guarding the valley, ordinary mortals, no matter how high your martial arts are, it will be useless. Nangong Du was silent for a long time, suddenly looked up to the sky and smiled, and stopped after a while, his eyes seemed to have tears, but they revealed a sadness and madness.

He said: "The people in the rivers and lakes say that they are not seeking fame and fortune, and their righteousness is thin and cloudy, but for such a so-called treasure, what Yin and Yang Tower, what treasure, what key, these rumors are really ridiculous, but I didn't expect that these ridiculous rumors cost my whole family their lives." I have been playing with the iris since I was a child, and I have never heard my father say anything special about it, let alone any treasure, except for its strange shape. If there really is, then my father holds the key to the Yin-Yang Tower, why not open the Yin-Yang Tower himself and keep the treasure for himself. After listening to him vent his emotions, the lark said: "However, I heard our pavilion master say that the reason why your Nangong family has an iris knife is because you are the guardian of the treasure, so the iris knife can only be opened with your blood, and others get it is just a piece of scrap iron?" She hadn't seen the iris knife unfolded, so she looked at Nangong Du with an inquiring gaze.

Nangong Du's heart moved, and he calmed down a little before he said, "How do you pavilion masters know this?" Skylark said: "This has to be said, after the ghost car washed its hands, the rumors about the Yin-Yang Tower came out, and the pavilion master naturally wanted to go to the Yin-Yang Tower to find this treasure." So the pavilion master has been sending people to secretly investigate the news of the Feng Yu brothers and sisters all these years, while secretly monitoring the ghost car. Until I found out that someone had been looking for a ghost car, that person was you, the descendant of the Nangong family-" Skylark paused and said: "Actually, do you think that you can deal with the world-famous Thousand Bird Pavilion for so long with your own strength?" After you killed the first person from the Thousand Birdstooth Pavilion, we have already found out who you are and what your purpose is. However, the pavilion master used you to find out the ghost car, and you were the descendant of Nangong and the real owner of the iris knife, so the pavilion master decided not to kill you first, but just sent people to constantly harass you, as well as ...... Trace. After the lark finished saying this long paragraph, he stopped and looked at Nangong Du quietly.

After listening to the lark's words, Nangong Du realized that he was being played with by this Thousand Bird Pavilion, but all of this was because of this treasure of the Yin and Yang Tower.

Nangong Du was angry and hateful in his heart, and said angrily: "When I go out from here, the first thing is to go to the Valley of Tricks, I will definitely go and see in person, what the Yin soldiers look like, what the Yin Yang Tower looks like, and what treasures are in it!" He was in a state of agitation, causing a poisonous attack, and his blood surged, and he fell to the ground again.

In the next period of time, Nangong Du didn't know the time, he woke up and fell asleep, when he was awake, he wanted to use his internal strength and cheer up, but he felt that the dantian was empty, the more he was lucky, the more he felt that his body was soft, he couldn't support it, and he fell asleep again.

This sleep seemed to have been a long and long sleep, and he woke up a few times in the middle, only to feel that the lark carried him on his back and walked in the mountains, he fell asleep countless times, and woke up again, and his blurred vision was always the shaking mountain road and the thin and bumpy shoulders of the lark......
