What is the world's most essential appearance? How does it exist?

These metaphysical questions will always be explored and pondered by a group of pioneers in every place and at every time.

The purest curiosity about the nature of the world we live in transcends race, time and space.

In Zhao Rong's eyes.

These metaphysical things were widely called 'truth' in previous lives.

Seeked by a group of philosophers and scientists.

And in this world, its name is 'Tao'.

Chased by various schools of thought and thousands of mountain climbing monks.

They are all 'catechumens'.

It’s just that the situations in different worlds are very different because of different unknown laws.

In the Xuanhuang cultivation world, powerful cultivators may not necessarily be obsessed with the Great Dao, but worship "power". However, those "admirers" who are obsessed with the Great Dao and can explore it in depth are all mountain-top powers who can reverse yin and yang, pluck hearts and hold the moon.

This is the case with Confucianism, Mohism, Taoism, and the Hundred Schools of Thought.

Obviously, Zhao Xifu, Zhu Yourong, Yu Huaijin and others in Xia Chong Zhai are inclined to be "admirers".

This is also the reason why Zhao Rong first proposed the "Achilles cannot catch up with the tortoise paradox".

However, he never expected that their reaction would be so intense, and that the subsequent developments would be so uncontrollable...

Originally, Zhao Rong just wanted to say something interesting to 'fool' Manager Zhao into drinking a few glasses of Bingniang wine, just like the color blindness paradox he had mentioned before.

But the fact is, he actually overlooked something:

Anywhere in the Three Thousand Worlds, the most important and fundamental exploration of 'metaphysics', or 'Tao', is... time and space.

The former is what is commonly referred to as the Long River of Time in the Xuanhuang Realm Mountains. However, the cultivators in this world seem to be affected by some factors in exploring the essence of the existence of the Long River of Time and space, which is very difficult and far behind Zhao Rong's previous life.

And tonight, the second paradox he proposed deeply involves the nature of time and space...

In a remote and old restaurant in Duyou City at the end of the world, Zhao Rong calmly and firmly said, "Time and space are not absolutely continuous."

It was like a bolt of thunder that struck out of nowhere. The whole place was silent and everyone felt deafened.

Before anyone could raise their voices of surprise, Zhao Xifu, who had been singing the opposite tune, suddenly spoke and poured wine, catching everyone off guard...

At this moment, Zhao Rong was looking at the clear glass of wine carefully.

In the wine glass, the water surface reflected the dim orange light in the hall, but it was not dazzling. Instead, it gave people a crystal clear feeling, with clear bottom.

Like a spring pouring and leaping along the mountain road in the forest in the early morning.

In the quiet hall, like everyone else, Zhao Rong looked at it curiously for a while, then raised his eyes and looked at the shopkeeper who was pouring the wine and the black wine jug in his hand.

Zhao Rong remembered that he had just poured out all the Bingniang wine.

But why now... more wine is being poured out?

"What kind of wine is this?" Zhao Rong frowned slightly.

It turns out that this black wine jug also hides a mystery?

Zhao Xifu did not answer, but turned his head and stared at the door.

It was as if he didn't hear what Zhao Rong said, or rather... he was ignoring him.

The shopkeeper looked at the door quietly for a while, then suddenly raised his foot, left Zhao Rong and walked towards the door.

On the way, he sighed deeply, and muttered with a sense of realization:

"Discontinuous...discontinuous, can't it be divided into smaller parts? Oh, is this what the 'water' in this broken river is like? I've been dealing with it for so many years, damn it, I'm only now figuring it out..."

Zhao Xifu rubbed his face.

Zhu Yourong couldn't help but speak at this time: "Manager Zhao, are you saying that Ziyu's words are true?"

There was some uncontrollable excitement in her voice.

Zhao Xifu nodded.

Zhu Yourong stood up in an instant, supporting herself on the table with both hands, her red lips and white teeth trembling slightly... If the 'paradox' and the answer from Ziyu's mouth were to be passed on to Tunanzhou, I wonder what a huge shock it would cause in the Jixia Academy!

She couldn't help but turn her beautiful eyes to look at the young scholar who invited them to drink tonight.

Zhao Rong looked as if nothing had happened. When Zhao Xifu didn't answer him, he looked at the glass of clear wine with curiosity.

Zhu Yourong's breath was slightly choked... Does this guy know what he has done? His paradox and answer reveal the essence of the long river of time and space! Even if it is just a 'simple' answer to whether time and space can be infinitely divided, it involves one of the most fundamental characteristics of the great way of heaven and earth.

As far as she knew, before today, the sages of the Xuanhuang Realm had always held the view that time, all things, and even the flow of the long river of time were "continuous" and could be divided infinitely. This was also an almost obvious conclusion that everyone could subjectively feel.

In the past, this conclusion would have been almost beyond doubt. However, tonight, a certain guy not only proposed a paradox to question the continuity of time and space, but also gave a definite answer! He directly took two steps forward.

If his words were correct, then if Zhao Rong were now in the Jixia Academy where one could 'prove the great Dao', his words would cause strange phenomena in heaven and earth, with white rainbows piercing the sun, clouds and dragons spitting pearls, and colorful mist and clouds... It's a pity that this is not the place to prove the Dao.

The woman in Confucian clothes with her chest bound couldn't help but take a deep breath and took several breaths in succession.

She didn't even have time to care about the pain from the bra wrap caused by her intense breathing. Instead, her beautiful eyes were fixed on Zhao Rong. Her long eyelashes trembled. She wanted to speak several times but was hesitant every time.

Just as Zhu Yourong was shocked, other people also had different reactions.

Although Yu Huaijin did not have as much knowledge as her teacher, she also vaguely sensed a certain "horror" behind this strange paradox and the answer. She had never seen these views in any book before.

This old-fashioned girl who came all the way to the ends of the earth to study stared at the young Confucian scholar who interrupted her at Ruexingtang. For a moment, she seemed unable to move and was in a daze.

As for Zhao Lingfei, Su Xiaoxiao, Zhao Qianer, Li Xueyou, Jingzi, etc., because the discussion of Zhao Rong, Zhao Xifu, Zhu Yourong and others on the scene was beyond their understanding, so after listening to it in a daze, the expressions of these girls were all...

I didn't understand, but I was shocked.

But even if Zhao Lingfei, Su Xiaoxiao and others didn't understand, they were not stupid. They could see the violent reactions of Zhao Xifu and Zhu Yourong after Zhao Rong finished speaking... They were clearly shocked.

So their eyes all fell on Zhao Rong, and their expressions were different.

Su Xiaoxiao's little head was turning and turning in thought... Hmm, does it make any difference whether the water in the river is continuous or not? Why is she so confused about this light?

However, although she couldn't figure it out, she didn't get bogged down in it. Just like other little worries that had popped up in her mind in the past, the little fox demon quickly put them behind her.

She doesn't understand, but as long as Zhao Lang understands, it's enough. Besides.

The little fox demon secretly glanced at the faces of everyone in the circle and was secretly happy.

Su Xiaoxiao felt that as long as she could see whether Zhao Lang was showing off, there would be no problem.

The little fox demon is not unfamiliar with the reactions and performances of the people on the field, and wants to say, "I am very familiar with this."

This is how Zhao Lang shocked the entire audience in the much-anticipated Confucian-Taoist debate in Zhongnan Kingdom, and won the debate against the Taoist gentleman.

She was the first one to cheer and clap her hands at that time.

And that day in the Liangjing Palace of the Great Wei Dynasty, Zhao Lang talked eloquently, making the uncle in the luxurious and solemn dragon robe bow his head and respectfully call him "Sir"...

The little fox demon hummed happily in her heart for a while, then glanced sideways at the expression of the woman with autumn eyes opposite her.

There was a dazed look on Zhao Lingfei's pretty face as she looked at the young Confucian scholar who had become the focus.

Su Xiaoxiao's fox eyes secretly curved like a pair of crescent moons.

She thought to herself: Hmm, this Zhao Xian...sister, she was so surprised even when Zhao Lang casually showed her hand. It was obvious that she didn't often accompany Zhao Lang and only cared about her own practice. Hmm, Xiao Xiao accompanied Zhao Lang through many things along the way, and Zhao Lang said... not accompanying is the most lasting confession.

Thinking of this, the happy smile on the little fox demon's pink lips gradually faded.

She suddenly felt like crying... My... My Zhao Lang... Originally my...

For a moment, no one on the field noticed Su Xiaoxiao's sudden sadness, and all their attention was focused on Zhao Rong.

Zhu Yourong wanted to raise his hand to grab Zhao Rong's sleeve.

Just like sometimes when they were writing privately with him in the study of Yilanxuan, when she came across a word she couldn't write well, he would think for a moment and then casually pick up the pen to write it down. Zhu Yourong would happily reach out and grab his sleeve, asking this enemy to teach her quickly.

He would always smile and keep things a secret to get a beating... just like an enemy...

At this moment, Zhu Yourong was about to raise his hand, but then he put it down silently, frowned at Zhao Rong and said, "Ziyu, you said before that you saw it from a certain book. Where is that book? Have you really forgotten it?"

Just as Zhao Rong was about to nod seriously, Zhao Xifu chuckled and glanced at Zhao Rong with an expression that said, "Who are you trying to fool, you little bastard?"

Seeing this, Zhu Yourong pursed her lips, and remembered that this enemy liked to keep people in suspense and fool people, sometimes making it difficult for people to figure out whether his words were true or false.

Bad Zi Yu, it’s already this time and you’re still trying to trick me… She was a little angry and glared at Zhao Rong who was blinking.

"Manager Zhao, please don't talk nonsense. How could I lie to you? I really read it in a miscellaneous book." Zhao Rong felt it necessary to reiterate it. Well, it's just that this miscellaneous book is not in the Xuanhuang Realm...

Everyone didn't believe him and thought he was being modest.

Zhao Xifu glanced at the glass of wine in front of Zhao Rong and sneered.

Zhao Rong coughed and didn't explain further.

He pointed to the glass of wine that was as clear as spring water:

"What kind of wine is this? Could it be... Uncle, you are too polite. We are no match for each other. Qingjun has already troubled you by borrowing your kitchen to cook tonight. Now I can't help but take out the precious wine. This is too... Hmm, is this a summer insect or a Qushi?"

Zhao Rong was speaking sincerely, but the next second his expression changed and he asked curiously. "It's not that I dislike you, I'm just asking out of curiosity."

"..." Zhao Xifu felt that if he stayed with this brat any longer, he would get eye twitching... Ugh, we're not friends with each other, don't try to be so familiar with me.

He said expressionlessly, "It's yours. You'll know after you drink it. Don't ask me."

The shopkeeper came to the closed wooden door, looked up at the clock hanging on the door, and glanced outside through the hole in the screen of the wooden door.

Zhao Rong nodded, picked up the wine glass and was about to drink it.

"etc."

The sword spirit in the heart lake suddenly said.

"He's shaking you. It's useless for you to drink. It may even be... harmful."

Zhao Rong asked seriously, "What kind of wine is this?"

Gui was quiet for a moment, "This is probably a rare place for enlightenment."

Zhao Rong's heart trembled.

The sword spirit said in a deep voice, "Give it to your first wife or second wife, or your old lover."

Zhao Rong was stunned for a moment, "Xiao Xiao?"

"No, this is the smaller one. It's the one with the biggest breasts and the most dignified look."

The corner of Zhao Rong's mouth twitched violently, and he couldn't help cursing in his heart:

"Can you please stop making such jokes? The relationship between Zhu Yourong and I is not what you think. We are normal teacher and student, and our relationship is that of both teacher and friend. Don't taint us with your dirty thoughts!"

He was a little angry.

"Oh, teachers and students...it's not like we haven't seen this kind of thing before. Don't you scholars like this kind of tune? In addition to female teachers, there are also teacher's wives and so on..." Gui said disdainfully.

"Shut up. I can't explain this to you, so don't talk nonsense."

"If it's normal for a teacher and a student, would they write secretly on each other's hands in public?" The sword spirit was amazed. "Does this require your advice? Scholars really know how to have fun. Even their flirting is so elegant. This time they wrote on the palm of the hand. Where will they write next time?"

"I..." Zhao Rong.

Wait, why do I feel like you, a crappy sword spirit, know everything?

The two of them only exchanged a few quick words for a few breaths, and Zhao Rong's face soon turned dark.

Gui thought for a moment and said firmly, "According to my experience, if you two keep flirting with each other like this, you will end up together sooner or later..."

Without waiting for it to finish, Zhao Rong left the Heart Lake and ignored the poisonous-tongued sword spirit.

The next second, he moved.

At this moment, in the sight of everyone else, Zhao Rong saw that after hearing Zhao Xifu's words and picking up the wine glass, his hand movements suddenly stopped.

Then he lowered his eyelids, was quiet for a few breaths, suddenly raised his eyes, and handed the wine glass to Concubine Zhao Lingfei without saying a word.

"Qingjun, drink it."

Zhao Rong said seriously.

Concubine Zhao Ling was stunned for a moment, shook her head, and tried to refuse, "Brother Rong'er, I told you that I don't drink this wine, you drink it..."

"Qing Jun." Zhao Rong interrupted softly.

At the door, with his back to the crowd, he folded his arms and looked at Zhao Xifu outside, his eyes slightly narrowed.

Concubine Zhao Ling frowned slightly and wanted to ask.

Zhao Rong was having some guesses in his mind, and the thoughts were getting stronger and stronger. He stared at Zhao Lingfei's beautiful eyes seriously, squinted his eyes and repeated:

"I drank it."

Concubine Zhao Ling raised the glass without hesitation, tilted her head back, and drank the glass of wine that was as clear as spring water.

The autumn-eyed girl immediately became obedient.

It all happened in an instant.

Just as everyone reacted, Concubine Zhao Ling had already put down her wine glass.

She put down the wine glass gently, and at this moment, the bottom of the glass was only a few centimeters away from the table.

Next second.

The wine glasses touched the table.

“Knock!”

There was a loud bang! It was like a knock on everyone's forehead, making their teeth chatter.

No one spoke.

For a moment, the sound of the cup falling echoed back and forth in the dim orange light of the hall, just like the first ring of a morning bell on the top of the mountain in the early morning, welcoming the bright rising sun.

With everyone's eyes focused on her, Concubine Zhao Ling sat upright with her waist straight, and slowly loosened her hands that were holding the cup.

Under her hands, the wine glass that had once contained a certain wine turned into powder.

Silently.

At this moment, the tavern was closed, there was not a trace of wind, and everyone's breathing was even softer.

The wine glass turned into powder, which flew up with the wind, swirled upward, drew a whirlwind trajectory, and then scattered.

However, when part of the powder flew about a foot above and in front of Zhao Lingfei's right shoulder, it seemed to encounter some transparent obstacles...

The powder vaguely outlined the shape of a small sword.

In just a moment, the dust had disappeared.

The sword disappeared.

Before everyone could open their eyes and take a closer look, a small handleless sword appeared one foot above Zhao Lingfei's left shoulder.

It is exquisite, slender and miniature, just like a slim girl.

Zhao Rong was very familiar with this sword. It was the physical sword of Qingjun's natal flying sword Qingmei in his heart lake. However, Qingjun seemed to have not yet collected the special materials and forged it completely, so he rarely took it out.

However, at this moment, under the astonished gazes, Qingmei appeared and... roared with all her might!

Clang——!

The clear sound of Qingmei's sword seemed to be joy, like... a welcome.

The next second, a sword sound that was clearer than the sound of Qingmei Sword suddenly resounded throughout Xia Chongzhai.

Clang——!

Li Xueyu, who had a mortal constitution, couldn't help but cover her ears, and then her hand was gently held by Yu Huaijin, who had a frown on his face.

When this strange sword sound suddenly appeared, the two sword cultivators in Xia Chong Zhai, except for the woman with autumn eyes, immediately took action...

Zhao Xifu, who hadn't touched a sword for a long time, crossed his arms and slowly turned around.

Zhao Qian'er suddenly stood up from her seat and said excitedly, "Miss!"

Concubine Zhao Ling pursed her lips quietly, as if she didn't hear anything and didn't look at them.

The woman with autumn eyes lowered her head and calmly looked at the slender hand that had just held the cup, somewhat absent-mindedly.

She suddenly turned around and said to her husband seriously:

"It seems... I'm waiting again."

Zhao Rong raised his eyebrows... again?
