After listening to the explanation, Feng Jin felt a sudden enlightenment and couldn't help but chase:

"What is the tough day and what is the soft day?"

Ruan Xian looked at Lin Fengjin deeply, and a smile appeared on his wrinkled old face, but he said to Ren Mo:

"You come and answer him."

Ren Mo said in a little embarrassedly:

"Master Ruan! This is the secret of our institute that is not passed down!"

Sun Jue also said immediately:

"Yes, even external disciples must be admitted for two years, and the credits in the academy must be accumulated to 15 points before they are eligible to be awarded.

Ruan Xian waved his hand and said:

"This is my agreement to exchange for this kid. If I don't explain it clearly to him, wouldn't it mean that I'm coaxing him?"

Ren Mo said with a bitter face:

"If Master knows, I will be punished."

Ruan Xian said unhappily:

"If you have any questions, I will naturally tell him!"

Ren Mo had no choice but to say seriously to Lin Fengjin:

"There are many sayings about the hard day and soft day, but our Donglin disciples regard sunny days as the hard day and cloudy days as the soft day."

Lin Fengjin nodded and was taught, and he suddenly said:

"What about rainy days? What day is this?"

Ren Mo said:

"Rainy days are miserable days. There are records in ancient books: miserable rain is miserable. Oh, Brother Lin, you are too scheming!"

Lin Fengjin laughed loudly, but comforted Ren Mo:

"I just asked casually, Brother Ren Mo doesn't have to care."

He then asked Ruan Xian again:

"Just just heard Master Ruan's teachings, I suddenly realized, but why hasn't the little finger been mentioned in the usage of this glove? If you use the little finger, what is the use of the extracted nourishing essence?"

Ruan Xian sighed and shook his head and smiled bitterly, but laughed at Ren Mo and others and scolded:

"You are now far more talented than this kid, but there is one thing you should learn from him, that is, the thickness of your face! In the process of seeking the Tao, you should learn from this kid's spirit of being shameless."

Then Ruan Xian turned around and said to Lin Fengjin:

"I will answer you again because your question is still related to Baicaolu, but after answering this time, the transaction will be completed. If you want to ask me questions, you have to exchange something that you like to see in some family!"

Lin Fengjin smiled and said:

"This is for granted."

Ruan Xian said:

"The little finger is a waste and a demon! Then the essence of grass and trees squeezed out with it is useless to people."

Lin Fengjin quickly noticed the word "to the person" and immediately repeated it instinctively:

"Not useful to people?"

Ruan Xian twisted his beard and said:

"Yes, if you encounter a demon or a ghost, you will like it very much. I heard that the Medicine King Pestle is in the hands of the King Li Jian of the Middle Tang Dynasty. His mount, the Fire Char Beast, takes the Medicine King Pestle, and uses the essence extracted by similar methods every day, so he has always been willing to be the mount of the Li royal family."

Lin Fengjin nodded and lowered his head to ponder for a while, and suddenly said:

"I wonder if my senior has ever heard of the secret technique of demon refining?"

Ruan Xian was stunned and said:

"I have heard of this, but it is said that this secret technique is extremely rare and effective, but the negative effect is also a very great technique, just like drinking poison to quench thirst."

Lin Fengjin smiled and said:

"I have a demon weapon refined by demon refining techniques."

As he said that, Lin Fengjin greeted his servants from afar, and asked Lin De to take out the patchwork vest belonging to the dog king that he had collected, and then present it to everyone.

Like Ren Mo and others, they couldn't see what this thing was useful. Ruan Xian said oh, reached out and grabbed it, and the vest flew directly into his hand. The old man drank and ate peanuts while studying it for a while, and then said:

"It's indeed a bit amazing--,"

Lin Feng said seriously but cautiously:

"Senior, be careful. Although this object is extremely powerful, it must first absorb the wearer's essence and blood when used!"

Ruan Xian waved his hand and said:

"It's okay."

But he said to Ren Mo, Gu Xian and Sun Jue:

"You all stabbed this vest together."

The disciples of Donglin Academy may not be both civil and military, but at this time, the three sons of Donglin were sent to travel as the face of the academy. They are all figures that can travel the world with one book and one sword. The swords on their waists are not a decoration!

At this time, they drew their swords and stabbed them as Ruan Xian took a deep breath, and the three sons immediately saw the black aura that turned into a strange black aura, holding their sword tip tightly, and not being able to make progress! Lin Fengjin called out with concern:

"careful!"

However, Ruan Xian laughed loudly, and when he waved his hand, all the strangeness disappeared. However, the third son of Donglin seemed a little surprised. It was obviously the first time he encountered such an evil thing. Ruan Xian played with the Baina vest for a while and waved his hand and said:

"Although this thing is nothing great, it's rare. Just tell me what you want, right?"

Lin Fengjin said seriously: - There are a few questions that I want to ask my senior to resolve the doubts."!

Ruan Xian thought about it and laughed:

"You little guy is very cunning. What are you talking about first?"

Lin Fengjin sighed and said:

"My first question is: In your heart, what is the Tao? My second question is one"

"Stop!" Ruan Xian, the old fox, couldn't help but smile bitterly after hearing Lin Fengjin's words:

"Fortunately, I listened to your question first, otherwise you would definitely be your kid's condom! It's a pity that it's not convenient for me to speak back. Once this happens, this vest can only ask one question. If you want, then ask. If you don't want to, take this thing away."

Lin Fengjin said very simply:

"Okay! This demon-refined Baina vest is the senior. The first question I asked is: what is Tao."

This problem has troubled Lin Fengjin for too long. Even though he was a human being for two lifetimes and had the wisdom of modern people, he still could not understand the meaning of this.

Ruan Xian smiled and suddenly brushed his sleeves lightly. Lin Fengjin had already used his demonic power to quickly slow down the flow of time, but he felt a flash of sight. Then the air all over his body seemed to have turned into an air cushion, rolling himself and Ruan Xian at the top of the tower not far away and flew straight over, floating like a wind flying.

Just on the roof of the building, Ruan Xian stood with his hands behind his back, his gray hair and beards floating quietly in the wind. After a long time, he looked up at a crescent moon in the sky and said to Lin Fengjin:

"When the moon is not full, the light increases day by day, which is the "way of heaven". Rain falls in the sky and falls on the ground. When it is full, it flows to low-lying places. This is the "way". Humanity is ever-changing, and everyone does its own thing. The humanity I follow is to read the "Book of Changes" at the age of thirty, and understand the ultimate truth of evil and humility. "Evil" means disgust, "fear", fear of "full", fear of complacency, and humility is my humanity!"

"The way of heaven, the way of earth, and the way of humanity are united! That is the way of heaven!"

Lin Fengjin was originally very difficult and obscure when practicing the human hunting technique. Even if he made progress, he was like a person forcibly squeezing from an extremely narrow cave forward, and his whole body was rubbed and covered in bruises. After hearing this sentence, he suddenly felt enlightened.

Because the great way of truth under the world is originally a different path.

After saying these few words, Ruan Xian floated away in front of Lin Fengjin's eyes.

It was really floating!! Lin Fengjin even felt that the old man seemed to have dissolved into the wind at this moment, and he even saw that the gust of wind blew towards the pavilion in the lotus pond, and then, what Lin Fengjin couldn't understand the most happened:

The pavilion was originally built of dry wood, and painted on it to prevent moths. However, when Ruan Xian flew past, the wood of the pavilion was rejuvenated, and bark, roots, branches and green leaves were quickly grown at an extremely fast speed, and green vines were wrapped around it, forming the wonder of a living pavilion!

Immediately afterwards, the two columns with the couplet written by "Storm" fell off on their own, and then flew away by the wind! However, the pavilion that lost the two columns did not collapse because of the green vines and the support of the living trees and branches.

"According to the laws of nature and integrating into it, this is the source of Ruan Xian's magical powers." Lin Fengjin murmured.

He stayed on the roof for a while and suddenly screamed:

"Linde! Fu Yingxiong!! Lift the ladder for me. If I want to jump down at such a high level, wouldn't I break my leg?"

As soon as Ruan Xian left, the three sons of Donglin also said goodbye one after another. However, before leaving, Ren Mo also grabbed Lin Fengjin and said meaningfully:

"Brother Lin, if your servant Wang Tie remembers the things about Fengyu couplet again, please be sure to notify me."

Lin Fengjin is also a very thick-skinned person, and immediately said righteously:

"Of course this is certain!"

He hesitated for a moment, and suddenly asked Ren Mo again:

"Senior Ruan has such supernatural powers, and he should be one of the best in Donglin Academy.

Ren Mo smiled and said:

"Master Ruan has a humble and calm personality, and plays in the world, and his cultivation is naturally profound. However, the one with the strongest killer in Ruolun Academy is the young master Hai who is known as the feather of the eternal clouds, and Gu Xian's master, Mr. Jiuyuan!"
