"Brother Du?!" Xu Xian looked at the young man in white with astonishment, "Why are you here?"

"Don't worry, I'm not here to look for you." Du Qian casually replied to Xu Xian, then smiled at Master Zishan and said, "I'm Du Qian. I've heard of your great name for a long time. It's a great honor to meet you today!"

"It turns out to be Fellow Daoist Du..."

Master Zishan bowed politely and cast a puzzled look at Xu Xian.

Xu Xian understood and quickly transmitted his message: "He is the one who used the math formula to test my disciple!"

Is it him?

Master Zishan was slightly startled, then frowned tightly.

As early as when Xu Xian sent him the message, he was extremely shocked that someone could say the five words "odd changes, even remains unchanged", but at that time he was worried about the safety of his disciple, so he could only suppress the shock and suspicion in his heart temporarily.

Now, with Du Qian in front of him, all the thousands of thoughts that had been suppressed in Master Zishan's heart finally came out at once.

The mathematical knowledge he taught Xu Xian all came from the system and later generations, and the level was far beyond that of this era. The formula of odd numbers changing but even numbers remaining unchanged was not spread until the 1970s and 1980s.

There are only two possibilities for Du Qian to be able to express this in this era.

One is to learn from their master and apprentice, such as reading memories, stealing knowledge and eavesdropping.

And these two...

Master Zishan endured the tingling sensation on his scalp and cautiously asked, "Is Daoist Fellow Du also a cultivator?"

Du Qian smiled and said, "Yes."

Master Zishan bowed and asked, "Where is Youxian Township?"

Du Qian smiled and slowly said eight words: "Beside the Huangpu River, next to the Pearl Tower!"

Xu Xian, Bai Suzhen and others nearby did not know the meaning of these eight words.

But Master Zishan knew it very well. His body shook, his pupils shrank suddenly, and a storm surged in his heart.

Bai Suzhen pondered for a moment, and said with a puzzled look on her face: "Maybe the Immortal remembered the name of the river wrongly? I have been to the Huangpu River, but I have never heard of any Pearl Tower nearby!"

“…”

Du Qian glanced at her and said with a smile: "No, there is indeed an Oriental Pearl Tower on the bank of the Huangpu River. Just because you can't see it doesn't mean that others can't see it... Am I right, Fellow Daoist Zishan?"

When saying the last sentence, Du Qian cast his half-smiley gaze towards Master Zishan.

Zishan Zhenren recovered from his shock, glanced at the golden-armored general behind Du Qian, and said calmly, "Did Daoist really come from the Pearl Tower?"

Du Qian smiled and replied, "Why would I lie to you?"

After saying this, without waiting for Master Zishan to respond, Du Qian continued, "I know you have a lot of concerns and doubts now, but it doesn't matter. When you are more than halfway, I will answer them one by one for you."

"As for now, you'd better listen to me."

Du Qian glanced at the sky above his head and said with a smile: "Otherwise, you have to think carefully about what that monkey did five hundred years ago..."

Master Zishan's heart trembled, and he immediately followed Du Qian's gaze. As expected, he found that a heavy and oppressive feeling that was difficult to describe in words was pressing down from the higher sky.

——The Jade Emperor’s heavenly soldiers are coming!

Xu Xian, Bai Suzhen and others were all shocked.

Xiaoqing looked panicked, and quickly tugged at her sister's sleeve, whispering, "Sister, just listen to him!"

Since the return of the gods a few years ago, there are only a few forces in this world that can compete with the Heavenly Court. The Banbudu Inn is the most mysterious and well-known one among them.

Without hesitation, Bai Suzhen immediately bowed respectfully and said, "Thank you very much for your help, Immortal!"

"Sure, sure!"

Du Qian answered with a smile while glancing at Xu Xian and Master Zishan.

Zishan Zhenren hesitated for a moment, sighed, and said, "Then let's do as you say!"

As soon as the words fell, everyone reached a consensus and immediately used their own methods to fly towards the foggy valley not far away.

After everyone disappeared in the fog, a dark cloud stretching for ten miles finally appeared on the horizon.

The dark clouds were piled up like a ladder, toppling over. On them stood figures, each wearing silver armor and holding a long spear. A large flag with the word "Li" stood upright in the clouds, fluttering in the wind and making rustling sounds.

In the center of these thousands of heavenly soldiers, there was a mighty general holding a small tower in his hand.

Next to the God General, a handsome young man wearing lotus armor, holding a fire spear, wearing a Hun Tian Ling around his waist, a Qian Kun Circle across his shoulder, and wearing a wind fire wheel, with two buns on his head, raised his eyebrows and asked in surprise:

"Didn't they say that a snake spirit stole the talisman? Where is the snake spirit?"

The mighty general glanced at him and said calmly, "He has taken more than half a step forward..."

Nezha glanced at the mist, then curled his lips and said, "Really? Then there's nothing we can do!"

As he spoke, he yawned and said in boredom, "This old Jade Emperor really doesn't know the importance of a matter. They are just two snake spirits. We only need to send a small general to lead more than a hundred heavenly soldiers to capture them. Why mobilize so many troops?"

"Not only have they sent the Heavenly King, but they are also sending me in person. This is really like using a butcher knife to kill a chicken!"

The mighty general glared at Nezha and said, "Be careful with your words!" After that, he transmitted his voice in a bad mood, "What do you know? That snake demon has a great background. She has the support of Lishan Laomu and Guanyin Bodhisattva. The mortal hero who has a connection with her has an even more amazing background. There is a possibility that the Purple Palace is behind him..."

"Purple Palace?" Nezha raised his eyebrows and asked in surprise, "Isn't it not built yet?"

Li Jing couldn't help but glare at him again.

Nezha suddenly realized, "The one above?"

Li Jing's expression eased slightly and he nodded.

Nezha rolled his eyes and said, "That's even more unnecessary...Okay, I thought there was really a fight today, but it turned out to be just a show of pretense. Boring, boring. I'm going to Guanjiangkou to find my second brother. Next time there's something like this, don't call me again!"

After saying that, Nezha leaped forward, drove the Wind Fire Wheel into flames, and flew away into the distance.

"you……"

Li Jing looked at Nezha's back with an angry face, his expression changing from gloomy to bright, but in the end he sighed helplessly.

At this moment, there seemed to be a prying eye below. Li Jing frowned and looked in the direction of the prying feeling. He saw a golden-armored god standing at the edge of the mist in the valley, looking at him expressionlessly.

When their eyes met, Li Jing frowned, then waved his hand and said calmly: "Sound the horn, withdraw the troops!"

Along with the sound of wind, thunder and drums, the dark clouds in the sky dissipated, the military flags disappeared, and the heavenly soldiers vanished.

The golden-armored general stood where he was, looking at the sky for a while, then turned around and slowly walked into the fog.

…

…

On the other side, at the Banbudu Inn, Yijiu’s two brothers had already arrived with three thousand soldiers.

Du Qian met with the two of them, confirmed their identities, and then asked them to lead their troops to garrison the Shenyu Tower.

As for Du Qian himself, he settled Xu Xian, Xiaoqing and Bai Suzhen in his room, and finally he had time to be alone with Master Zishan.

In a private room of the inn and restaurant that was not open to the public, Master Zishan sat at the table, looking across at Du Qian with a slightly frown.

After pondering for a long time, Master Zishan still hadn't figured out how to start the conversation.

Du Qian, who was standing opposite him, glanced at him, put down his wine glass with a smile, and asked curiously, "Fellow Daoist, are you a spirit from a mountain?"

Master Zishan was slightly startled and nodded hesitantly.

Du Qian suddenly realized: "No wonder his Taoist name is Zishan..."

Master Zishan twitched his lips, and finally couldn't help asking, "Daoyou Du, since my little disciple has let the cat out of the bag, why don't we speak frankly - Daoyou Du, you are also a time traveler, right?"

Du Qian smiled and nodded: "Not bad!"

True Man Zishan thought to himself that it was as expected, and then frowned and said, "Daoyou can make the half-step Yijiu Divine General obey your orders, so it is obvious that you have an extraordinary origin. But I have been in this world for nearly five hundred years. During this period, I was also a demon king. I boast that there are not many secrets in the three realms that can be hidden from me, but I have never heard of your name..."

"Who are you?"

Du Qian smiled and said, "Not many secrets can be hidden from you, which means there are still secrets in this world that you don't know, right?"

Master Zishan nodded: "Of course."

Du Qian asked leisurely: "Then do you know why the immortal god Buddha disappeared back then?"

Master Zishan fell silent. Du Qian had hit the nail on the head. This question really stumped him.

Du Qian smiled and said, "Because of a monkey."

"……monkey?"

Master Zishan's face was full of confusion.

As a traveler from the mythological world, when I hear the word monkey, the first thing that comes to my mind is definitely Sun Wukong who made a riot in the Heavenly Palace.

But then again, when the immortals and Buddhas disappeared, the catastrophe of the Journey to the West had already passed a hundred years ago, and the monkey was also obediently serving as the Fighting Buddha in Mount Emei, so how could it be related to him?

Du Qian smiled slightly: "I didn't say it was a monkey from this world."

Master Zishan was slightly startled and asked in astonishment: "Could it be... the upper realm?"

Du Qian was stunned for a moment, then smiled and said, "Have you also heard about the rumors in the upper realm?"

Master Zishan came back to his senses and nodded solemnly: "It is said that this world is just one of the three thousand small worlds, and there is an even more vast world above this world."

"But this is just a legend after all. No one can confirm it..."

Du Qian smiled and said, "Now you can prove it."

Master Zishan frowned and asked, "Where is the evidence?"

Du Qian said leisurely: "It's far away in the sky, but it's right in front of us!"

Master Zishan was slightly startled, and could not help but exclaimed: "You are from the upper realm!"
