"By the way, Brother Li, this Mogao Grotto is so big, can we enter each cave?" Li Xi asked casually.

"How is that possible!" Brother Li replied with a smile, "Most of the caves in the Mogao Grottoes are being restored now, and less than one-tenth of them can be opened for visits, and less than 40 of them are open!"

"Oh, I see!" Li Xi nodded understandingly.

I saw Li Xi quietly transmit a message to Tang Haoran and said, "Xiao Tang, how about it, after walking through these caves, did you find the entrance to the secret realm?"

"No, none of these caves have found the entrance to the secret realm. Tang Haoran replied, "But I have a faint feeling that this entrance must be hidden in a deeper cave." ”

Under the leadership of Brother Li, Li Xi and the three of them visited more than 20 caves in a row. In each cave, Li Xi glanced at Tang Haoran, but unfortunately every time he shook his head slightly, indicating that it was not this cave.

Finally, Brother Li took Li Xi and them to the last cave. I only heard my brother say: "This is the last cave we can visit, and we can't go inside!"

At the end of the cave, he was stopped with a thick chain, and a sign was hung on the chain, which read, "No non-staff are allowed to enter!" in red paint.

"Brother Li, but we haven't seen enough! Let's give some more money, can you think of a way, let's go in and have a look!" Tang Haoran said.

"Yo, young man, this is not good! It's not a matter of money, the state has already had regulations, and we don't dare to violate them!" Brother Li replied helplessly.

"Look...... When Tang Haoran was about to fight again, Li Xi pulled his arm and shook his head to stop him.

I only heard Li Xi say: "Then forget it, let's not embarrass Brother Li." The main thing is that this mural is so beautiful, we just want to see a little more, but it really doesn't work, forget it, it's okay!"

Tang Haoran sent a message to Li Xi and asked suspiciously, "Boss, the entrance to the secret realm is still inside, why don't we look for it?"

"It's not that I don't look for it, I definitely can't get in this situation now. Li Xi replied, "At night, when there is no one here, we will sneak over and look carefully." ”

"Oh, so that's the case!" Tang Haoran's eyes lit up and agreed, "Haha, I like to break into Mogao Grottoes at night, exciting!"

After the three of them finished visiting, they took Brother Li's car back to the hotel in Dunhuang.

Finally, when it was night, the sky was getting darker, Li Xi and Tang Haoran were ready to set off.

Li Xi did not take Su Xiaoxiao with him in this operation, because he felt that this was just a path-finding operation, and the fewer people the better, so as not to attract attention.

Su Xiaoxiao naturally obeyed Li Xi's words, so she stayed in the hotel and waited for them to come back.

As soon as Li Xi and Tang Haoran got out of the hotel, they moved quickly in the direction of Mogao Grottoes.

"Hmph, hmph, finally wait for you to act alone, this time look where you are going!" The Golden Eagle Daojun, who had been waiting outside the hotel, couldn't help but feel ecstatic in his heart when he saw Li Xi sneaking out of the hotel.

I saw him and the pig demon in the direction where Li Xi and the others disappeared, and they also hurriedly followed.

The area of the entire Dunhuang City was not large, and Li Xi and the others ran in the direction of the Mogao Grottoes for a while, and then came to the suburbs.

Tang Haoran saw that the moon was dark and the wind was high, and there was no one around, and the ring in his hand flashed, so he took out two talismans.

He said to Li Xi: "Boss, this is the speed talisman of my Taiyi Daomen, sticking it to my leg, you can increase your speed by more than three times!"

"Hey, you still have this good thing!" Li Xi took the talisman in surprise and stuck it on his calf according to Tang Haoran's appearance.

As soon as he put on the talisman, Li Xi instantly felt that his weight seemed to have lost a lot, and two air currents seemed to have been born out of thin air in his legs, pushing him to move forward continuously.

"Hehe, we still have a lot of good things in our Daomen!" Tang Haoran replied. "Boss, are you ready? Let's go!"

"Okay, let's go!" Li Xi responded.

I saw that the two of them suddenly increased their speed to the limit, and under the effect of the speed talisman, they seemed to turn into two black streamers, and galloped towards the direction of Mogao Grottoes at an extremely terrifying speed.

"What!" The Golden Eagle Daojun, who was following Li Xi in the distance, was suddenly taken aback, he felt that the speed of the two of them suddenly increased several times, and there was a faint feeling that he couldn't keep up.

"Hmph, dare to compete with me in speed! Taking advantage of the night, the giant eagle's wings waved hard, and its claws grabbed the pig demon on the ground, and flew in the direction of Li Xi.

Driven by the speed talisman, Li Xi and Tang Haoran rushed to the Mogao Grottoes that they had visited during the day.

The two of them did not stop at all, and with a whoosh, they crossed the duty room at the door and rushed straight into the cave.

The security guard on duty at the door only felt a flower in front of him, and it seemed that two black shadows rushed in front of him. He rubbed his eyes, and then looked intently, and saw that there was silence around him, and there was still a shadow somewhere.

"Damn, I won't see anything dirty!" the security guard was secretly frightened, scolded, and quickly hid in the duty room.

The Golden Eagle Daojun in the air watched Li Xi and them rush into the Mogao Grottoes, and he swept it in the air with his demon sense, sensing that the terrain in the Mogao Grottoes was complex and there were many caves.

Cautious by nature, he didn't want to rush in, so he stopped in the air and said secretly: "This Daojun is waiting for you outside, and you can't escape from the palm of Bendaojun's hand." Hmph!"

Li Xi and Tang Haoran were cautious after entering the Mogao Grottoes, but they did not attract anyone's attention. They explored all the way in, and soon crossed the blockade they had seen during the day.

The two went deeper and deeper, passing through more than 100 caves. Suddenly, Tang Haoran stopped, closed his eyes and concentrated for a moment, and said excitedly: "Boss, I sensed it, the entrance to the secret realm is in the cave ahead. ”

The two of them walked into it quickly, only to see that the area of this cave was not large, only about ten square meters. The interior was empty, except for a mural painted on a stone wall.

However, what is strange is that the stone wall in this cave is not painted with a pattern of Buddhism or a flying goddess, but a portrait of Taoist Taishang Laojun.

I saw that although this portrait of Taishang Laojun has a long history and has gone through wind and frost, it is still clearly visible and lifelike.

"That's right, the entrance is here!" Tang Haoran said excitedly, "According to the ancient records of my Taiyi Daomen, the great power that sealed the statue of the Blood Demon King back then was the immortal cultivator of my Daomen. Therefore, the mural at the entrance of this secret realm must be the content of my Taoism. ”

Hearing this, Li Xi touched the stone wall with his hand, and felt that the place in his hand was cold and hard, so he pushed it hard, and the stone wall did not move at all.

He asked, puzzled, "Where is this entrance?"

"Let me try!" Tang Haoran said, only to see him concentrating on his luck, chanting words in his mouth, and drawing a strange pattern on the wall with his hands.

In an instant, the portrait of Taishang Laojun on that wall suddenly lit up, and a burst of golden light erupted. The golden light lasted for a moment, then dissipated into nothingness, and nothing happened.

"It seems that what is written in the ancient books is true, and the entrance to the secret realm can only be opened on the night of the full moon. Tang Haoran said helplessly.

"On the night of the full moon, isn't there still more than half a month?" Li Xi said after calculating.

"There's no way, according to the ancient books, except for the night of the full moon, you can't open this entrance at any other time. Tang Haoran responded.

"Forget it, there is no way to do it, it seems that I have to go back first, and wait patiently until the day of the full moon to come back. But today, we have at least discovered the location of the entrance to the secret realm, and we have successfully completed the task!" Li Xi said.

After saying that, the two of them turned around and carefully walked out of the gate of the Mogao Grottoes along the route they had come.

The two of them rushed in the direction of Dunhuang City for a long time, at this time Li Xi seemed to feel that something was not right, he raised his head blankly and looked down at the sky, and said, "Hey, why is it so dark, I can't even see the moon!"

I saw a large black cloud hanging over the two of them, and even the moon in the sky was completely obscured.
