Dugu Yun agreed to Wu Daozi's words, and when he returned home, he never mentioned his plans to break into the outside world. Accompanied Wu Daozi to refine medicine all day long. Boredom, he practiced the small grappling skills and genius swordsmanship he learned from the two sisters of the Mo family several times. After practicing for a few days, he was already proficient, but he always felt that something was wrong, and asked Wu Daozi, but Wu Daozi couldn't say why, and couldn't help but be very frustrated.

Wu Daozi knew that Dugu Yun was now bent on learning martial arts, and he was very relieved. I only hope that Dugu Yun will learn martial arts as soon as possible, and he may be able to avenge his family in the future. But when I think of what happened back then, I can't help but worry. I thought to myself: "This kid has so many enemies, and the enemy is so powerful, it is not easy to take revenge." I'm afraid that as long as any enemy is concerned, he is not an opponent. Why waste his life again? Thinking of this, he originally planned to tell Sù Duguyun's life experience, but he couldn't help but hesitate. After thinking about it, I finally decided: "It's better not to let him know." Let him live happily for the rest of his life. ”

Duguyun looked at Wu Daozi in a daze and asked, "Grandpa, what's wrong with you?" Wu Daozi came back to his senses and said: "Grandpa is thinking, grandpa's father, that is, your grandfather was a master of medicine and martial arts. But when he came to his grandfather, he loved medical skills, and his martial arts were wasted, and he couldn't even beat the two offspring girls in Zhufu, so he was really ashamed. When Dugu Yun heard this, his eyes lit up, and he hurriedly took Wu Daozi's hand and asked, "It turns out that Master Zu's martial arts are also a must." Did he leave any cheats or anything like that?"

Wu Daozi said: "It seems to be, but it's been decades, and I've been in the wind and rain all these years, wandering around, and I don't know if it's lost." As he spoke, he pulled out a box from a cave in the cave. Dugu Yun was surprised in his heart, and thought: "I know everything in this cave, and I don't find that there is such a box here every day." It turns out that my grandfather also hid it from me. ”

Wu Daozi wiped the dust of the box and revealed his true face. But seeing that the vermilion around his body is shiny, the box has not been old for a long time, and it is obvious that the workmanship materials of the box are extremely precious. Dugu Yun was overjoyed, thinking: "This box is so well preserved, it must be an extremely precious thing inside, I don't know what kind of treasure it will be?" Wu Daozi put the box on the table, and Dugu Yun approached the box, wanting to reach out and touch it. Wu Daozi said: "Be careful, this box has a mechanism." You can't touch it. Duguyun was shocked when he heard this, and hurriedly retracted his hand.

Wu Daozi said: "Looking at Grandpa's technique, it's okay to start like this." But I saw him groping left and right, pressing up and down. The 'pop' box opened in response. I saw three books in the box. The written word is outdated. Wu Daozi took out the three books and found a hand, and handed one to Duguyun. I saw the words "Wuxin Jue" written on it. Dugu Yunqi said: "What kind of martial arts is this? What a strange name?" but saw Wu Daozi put the other two back into the box. Duguyun asked: "Those two are books again, why didn't Grandpa give them to Yun'er?"

Wu Daozi closed the box and said, "These two are forbidden books. What it is, grandpa doesn't know, when your grandfather passed it on to grandpa, he asked grandpa to just keep it, and let grandpa swear that he would never look at it in his lifetime. Grandpa doesn't know what the reason is. Dugu Yun said: "That grandfather gave it to Yun'er, and it is not a violation of the oath." Wu Daozi said: "No." Even grandpa can't look at it, so it's probably not a good thing. Here you go, grandpa is afraid that he will hurt you. It's still not good to look at. ”

Dugu Yun said: "That's not a good thing, so why not destroy it?" Wu Daozi said: "Your ancestor didn't say that he wanted to destroy it." That can't be destroyed. Duguyun couldn't help but wonder: "What the hell is this, it can't be destroyed, and others can't see it." Okay, anyway, I've memorized the way to open the box, and when you're not here one day, I'll secretly open it and see what happens. "I have made up my mind, and I will not ask any more. I opened the "Heartless Formula" in my hand and looked at it. Although Wu Daozi is a good doctor, he is not skilled in medical skills, but he is extremely dull. The words of the elders are just what they say, and they never disobey it at all. Not to be flexible. Just because he didn't pass it on to Duguyun. So much so that Duguyun suffered a lot later and almost took his life. This is a later story, and I will show it later.

Let's say, Duguyun opened the first page of "Heartless Formula", which read: Heartless, so-called, selfless, heartless, invincible and fearless, no tricks and no style. No stupidity, no greed, no desire, no thought. Duguyun saw that he didn't know what to do, and he didn't know where to start for a while. That and Wu Daozi Xiang, Wu Daozi was even more indifferent, and sighed: "If grandpa could understand, grandpa would have become a martial arts master a long time ago." So grandpa can't help you, as for how much you can comprehend, it depends on your own understanding. ”

Dugu Yun was frustrated, so he had to continue to look backwards in order to find a way out of it. "No Heart Formula" is an upper-level internal strength method. And the mental method is extremely profound, even if it is a martial arts master, most of them can't understand it, let alone practice it. This is also the reason why Wu Daozi can't practice.

Duguyun finished reading the book, and the first half of the book was a mantra for practicing internal skills. The second half is a martial arts move. He couldn't practice his internal skills, so he had to practice his moves first. The moves are also extremely subtle. He practiced hard every day, and practiced for more than a month with his intelligence, although he knew the moves, but after all, without the assistance of internal strength, he was powerless.

On this day, Dugu Yun got up very early to practice his sword as usual, and after practicing three times, he still made no progress, and he couldn't help but feel bored and unable to settle down. I can't practice anymore. Throw the wooden sword and sit down on a large rock to rest. After resting enough, I lost the interest in practicing, and I thought that there was nothing to do, and my grandfather was not at home, so why not go to the town to go to Xiao Yu'er to play. When I thought of playing, I couldn't help but say to myself, "I haven't seen Xiao Yu'er for a long time." I don't know how she is doing, whether she thinks about me, 'Brother Lin'. When I thought of it, Xiao Yu'er still didn't know her real name, and she still called Brother Lin Chang Lin and Brother Lin, and she was very proud in her heart.

As soon as Duguyun was about to leave the forest, he heard the sound of horses' hooves, from far to near, and in a blink of an eye, he was in front of him. The horses were extremely healthy, and there were twelve horses in the group. On each horse sat a man in brocade clothes, all with weapons, and all twelve of them were imposing. Dugu Yun was surprised, and thought to himself: "What day is today, where are so many martial arts people from?" The old man at the head has a somewhat gray beard. Le Ma walked forward to Dugu Yun, leaned down and asked, "Little friend, how to go to Zhujiazhuang?"
