The man walked into the dilapidated yard in front of him with the dog.

"Grandpa Xu, we're here to see you." Dogdan'er skillfully hung the two fish in his hand on a wooden shelf in the yard and shouted towards the dilapidated thatched hut.

"Did you bring the money?"

An old voice came from inside.

"Brought it." Goudan'er touched a dozen copper plates around his waist. These copper plates account for half of their income each time they go to sea.

As soon as Goudan'er finished speaking, an old man walked out of the dilapidated thatched hut, with his body hunched and his hair completely white.

The old man raised his head, looked at Goudan'er, glanced at the man again, and then said to Goudan'er: "Two people can pay two people's tuition." ”

The man hurriedly spoke: "I'm not here to study, I'll just sit in the yard, wait for the dog to get out of school, and we'll go back together." ”

The old man snorted coldly and said, "Whatever you want." ”

Then he picked up the dog and dragged him straight to the dilapidated thatched hut. With a bang, the weather-beaten door was shut, and in an instant, the sawdust was falling rapidly. The broken door persevered after all.

The man was not surprised, and found a piece of bluestone in the courtyard and sat down.

Looking up at the clear blue sky and looking at this quiet village, my heart became more and more peaceful for a while

He set his eyes on the broken hut.

A faint voice came from within, but it still fell to his ears word for word.

"Do you remember what you learned last time?" This is the voice of the old Xiucai.

"Remember, Grandpa Xu." This is the sound of a dog's ball.

"Okay, I'll test you, if you can't answer, you can take the money back, and don't come to me again from now on."

"Okay." The dog's voice was a little weak.

"Last time we talked about the scriptures of the saints, the unity of knowledge and action, why don't you talk about the unity of knowledge and action?"

"Back to the teacher, the last time the teacher talked about the knowledge of things, it means to exhaustively study the principles of things, so as to gain knowledge. And the unity of knowledge and action is that when the ancient sage Wang Yangming read the book of Zhu Dasheng, he did not understand much about the way of "learning from things", and decided to practice it first. So he sat in the court, Gezhu for seven days and nights, and finally found nothing, but he fell seriously ill. So as to realize the way of learning from things and the unity of knowledge and action. Learning from things must not be divorced from reality. A lot of experience, and even wisdom, needs to be discovered through practice, and it takes frustration and repetition to be understood by the heart, which is the unity of knowledge and action. ”

"Well, that's good." Yu Laoxiu stroked the white beard under his chin and said, "It can be regarded as a good understanding." The unity of knowledge and action is the road of the world, and only by implementing it can we understand the mystery and will inevitably have unexpected gains. ”

The man sitting in the courtyard heard the theory of the unity of knowledge and action, his eyes lit up, and he muttered: "Is the unity of knowledge and action?" ”

"To learn from things, we must first pay attention to the unity of knowledge and action."

The man sat in the courtyard and pondered hard, and there was some kind of information stirring in his mind, and some kind of Taoism was gradually stirring.

Yu Lao Xiucai said something later, but the man didn't listen to it at all. The idea of the unity of knowledge and action triggered a kind of information bombardment in the depths of his mind, which resonated with a certain idea that seemed to have existed for a long time in the depths of his mind.

By the time Goudan finished school, the sun was already setting, and the whole small village seemed dark. The man and the dog Dan'er walked down the road. The man asked, "What did you learn today?" ”

Goudan'er's eyes were bright, and he was interested for a while and began to talk endlessly.

"Xu Laoxiu is a good teacher, you have to study hard."

The man said earnestly.

"Yes, big brother." Goudan'er nodded heavily, "I'm also like Grandpa Xu, I was admitted to Xiucai, and at that time, Grandpa didn't have to go to sea every day." ”

"Haha, okay." The man laughed.

When he was about to get home, Goudan suddenly found the man in black in a circle outside the yard.

Goudan'er felt a little uncomfortable, and hurriedly said, "Big brother, let's go back quickly." ”

But before they could take a few steps, a figure flew out of the doorway.

"Grandpa." The dog barked hoarsely.

The person who flew out was none other than Grandpa, covered in blood, and blood was scattered all over the ground.

"Hmph, old immortal, if you had told that man where he was earlier, you wouldn't have to suffer from these flesh and skin."

A big man walked out, stepped on his grandfather's chest, and said in a fierce voice.

"Stop."

The man shouted, walked over and stared at the man.

"Who are you?" The man said word by word.

"Hehe, don't you even know who we are?" The man smiled, "It doesn't matter who we are, you must be the one we are looking for." ”

"What are you looking for me to do?"

"You killed Wang Tie?"

"It's me."

"Hey, good boy, you did it. Do you know who Wang Tie is? ”

"Who is Wang Tie, and what does it matter to me?"

"Boy, it's really a toast and don't eat and drink."

"I think you're toasting and don't eat and drink." The man raised his eyebrows, and suddenly kicked out, shouting, "It's a waste of time to talk so much nonsense with you." ”

In an instant, the man flew upside down like a kite with a broken string.

The man squatted down and helped the old man up, and the dog had already pounced on him with tears on his face, hugged the old man, and kept crying.

"Grandpa, grandpa."

"How are you?" The man also shouted in a panic, he reached out and put his palm against the old man's back, and the aura was transported into the old man's body.

But the old man began to cough up blood again, and the man quickly stopped. The old man's body was too weak to withstand the powerful aura at all.

Seeing this, the dog cried even more, and barked at his grandfather again and again.

"Big brother, save grandpa."

The man's face was dejected, he had just sensed that he knew that the old man had run out of oil, and even if Da Luo Jinxian came, it would be useless.

"Kid." Grandpa spoke with difficulty.

"Grandpa." The dog kept crying.

"Well, don't cry. Grandpa is old, it's time to go. You must follow Yu Laoxiu to study hard, and your big brother will take care of you in the future. ”

Grandpa looked up at the man with a look of hope in his eyes.

The man looked at his grandfather, tears flickering in his eyes, and finally nodded heavily.

Grandpa was relieved in an instant.

Immediately, he looked at the dog again, and said with difficulty: "Child, grandpa is gone." You have to listen to the big brother well. ”

"Grandpa." The dog cried, and the tears couldn't stop lying down.

Finally Grandpa closed his eyes.

"Grandpa." The dog barked bitterly.

The man trembled, Huo De raised his head and stared at dozens of men in black.

Then he said lightly: "How do you want to die?" ”

"Hmph, give it to me." There were people in the team who shouted, and immediately these dozens of people in black pounced on the man like hungry wolves.

"Humph!"

The man snorted coldly, took a step suddenly, and his body moved slightly, turning into a stream of light and shadow, directly shuttling through the crowd.

In an instant, he reappeared next to the dog. The dozens of men in black also fell down at this moment, their throats were slit, and blood spurted out like a fountain.

The faint smell of blood dissipated in the air, and the blood flowed and converged into a small river.

At the head of the village, this is the cemetery of a small fishing village.

The cemetery is full of tall artemisia grass, mounds rise and fall, and bluestone tablets are submerged in the artemisia grass.

There's the dog's father and mother lying here.

This time, Godan'er's grandfather will also be buried here.

A new mound was piled up, and a new cyan stele was erected.

Goudaner knelt in front of his grandfather's tombstone and didn't get up for a long time, until the early morning of the second day, Goudaner kowtowed three times and stood up. But the fists were clenched together, and even the knuckles turned white.

"Big brother, I want to learn martial arts." Dogdan'er glared, looked at the man, and said in an unquestionable tone.

The man did not refuse, stared at the dog and said word by word: "You have thought about it, practicing martial arts is not a simple process. You have to suffer a lot, and once you start, you have to stick with it forever. ”

"I've figured it out, big brother." Dog Dan'er said.

"Can you tell the big brother, why do you want to practice martial arts?"

Goudan'er clenched his fists tightly, a strong anger rose in his eyes, and he gritted his teeth and said two words: "Revenge." ”

"Have you figured it out? You don't have to guess to know that it was the mayor of Liyang Town who sent someone this time. Compared to him, there is a world of difference, and it is not easy to kill him. ”

"I've figured it out." Dog's Egg.

"Ugh."

The man let out a long sigh when he heard this, and wanted to say when it was time to retrigate the wrongs, but after thinking about it, this sentence was easy to say from his own mouth, but it was extremely difficult for the dog to do this.

Finally, he nodded and said, "Okay, as long as you want to learn, I will teach you." I just want to tell you, don't be blinded by hatred, after all, life is more than hatred. ”

The dog didn't speak, his little fist still clenched.

"Let's go, I have to go to Yu Lao Xiucai to read a familiar book today. Don't forget your grandfather's instructions. The man spoke, patting the dog on the shoulder.

"Hmm." Goudan'er nodded, and then walked towards Yu Lao Xiucai's house with the man again.

Yu Laoxiu was lying on a table in the dilapidated hut. As soon as the man and the dog stepped in, they felt a burst of extremely strong alcohol.

Sure enough, there were several empty jars on the table.

As if hearing someone coming, Yu Laoxiu stood up, grabbed the man and the dog, and said, "Sit down, we won't have classes today, drink." ”

The man wanted to say something more, but was glared at by Yu Laoxiu, and immediately shrank back.

"Today we only drink and nothing else. Dogs have to drink too. ”

Yu Lao Zhu said drunkly.
