Tianjizi and his party have not yet found the whereabouts of the foxes in the desert, and they do not know that the foxes have left at this time. But he still has a great gain, and that is to find the lost ancient city.

This castle was one of the twelve city-states of the Ulan Kingdom. The vassal king of this city-state was named Ubato, and he was a man of great ambitions.

Ubato kept his city-state in good order and amassed a great deal of wealth. He began to be dissatisfied with being the master of a city-state, so he secretly recruited troops and horses, preparing to overthrow the rule of the king of the Ulan kingdom and turn himself into the king of Ulan.

Just as Ubato's plan was about to succeed, one of his ministers secretly went to the king of Ulan to tell him. The king of Ulan was taken aback and immediately summoned the vassal kings of the other eleven city-states to discuss countermeasures.

Eventually, the king of Ulan and eleven other vassal kings led a large army to conquer Ubatoar. On the day of the decisive battle, the sound of fighting on the battlefield shook the earth, and Ubato fought alone for two days and two nights with a spear, and finally was outnumbered and killed by random arrows.

The king of Ulan refused to spare everyone in the city-state, and he wanted to cut down the grass and eradicate the roots, so he led a large army to storm the castle and slaughter the city. According to historical records, the streets and alleys of the city-state were full of blood, and the cries and screams of the elderly, women and children were shocking.

While the slaughter was underway, a thick cloud suddenly obscured the sun, and the city-state turned from day to night. Then the wind raged, and the yellow sand was swept into the sky, and then fell from the sky above the city-state with a clatter.

Seeing that the situation was not good, the king of Ulan led his army to withdraw from the city-state, but when they ran to the city wall, they found that the city gate had disappeared inexplicably, and there were exactly the same walls everywhere.

The falling yellow sand slowly drowned the chariots, horses, and terrified soldiers. The king of Ulan looked up to the sky and sighed, it seemed that this was heaven's punishment for his brutal slaughter of the city.

In this way, until all the soldiers were covered with yellow sand, the king of Ulan did not find the exit of the city-state, and he also slept in this mysterious city-state.

Since then, the city-state has disappeared from the face of the earth, but legends about the treasures hidden in the city-state have survived to this day.

Nie Yuanfeng and Long Jingtian listened to Wang Pengzhan tell the story of what had happened in the city-state, and their eyes widened and they couldn't believe that this was the truth. Could it be that a brutal massacre really took place in this mysterious castle in front of us, and is there really a treasure stored in Ubatoar hidden here?

Why has this city-state, which had disappeared from the face of the earth for more than 500 years, reappeared again today? All this is so incredible and irresistible allure.

Where is the entrance to the ancient city? If you can't find the entrance, you can't enter the ancient city, and you can't find the coveted treasures.

"Daoist Tianjizi, have you thought of a clue?"

Wang Pengzhan's eyes rolled unconsciously.

Tianjizi listened carefully to the story just now, and carefully analyzed every detail. He wondered if Ubato had designed the mechanism when he was building the city walls.

When the king of Ulan led a large army to attack the city-state, the mechanism was activated, so when the yellow sand fell in the sky, the king of Ulan could only sit back and wait for death.

But where is the mechanism? Tianjizi can't find any information from the story. Wang Pengzhan looked at Tianjizi and frowned, secretly happy in his heart, his conspiracy was succeeding step by step.

"Tianjizi Dao Chief, it's better for us to look for the entrance to the ancient city separately, so it will be more efficient. Wang Pengzhan suddenly suggested.

I raised my hands and feet in agreement. Nie Yuanfeng shouted.

Long Jingtian glanced at Nie Yuanfeng and muttered in a low voice: "The problem of mindlessness can't be changed even if it is the end of the world." ”

Wang Pengzhan saw that Tianjizi didn't speak, so he then suggested: "I am in a group with Liu Ruyan, and you are in a group of three." Whoever finds the entrance first leaves a triangular mark on the city wall, and when he sees this mark, he can enter later. ”

This is also a good suggestion, Tianjizi agreed to Wang Pengzhan's method, and the two groups acted separately. Wang Pengzhan walked towards the side of the city wall with Liu Ruyan, and he carefully observed the traces on the city wall as he walked.

Wang Pengzhan knocked the city wall, a strange smile appeared on his face, and he took out a pen and drew a triangle on the city wall.

"Is this the entrance to the ancient city?" asked Liu Ruyan, puzzled.

"Hmph!" Wang Pengzhan let out a sneer, "You don't care so much, just follow me anyway." ”

After speaking, Wang Pengzhan pulled Liu Ruyan and continued to walk forward. "Wait, since it's not the entrance, why do you want to draw a triangle there?

"Daoist Tianjizi, don't call you so close. Wang Pengzhan said a little angrily, "Don't trust others easily, who knows if they came to the desert for these treasures?"

"You are too unconscionable, don't forget that it was the Heavenly Machine Daoist who rescued us from danger. Liu Ruyan didn't expect Wang Pengzhan to be such an ungrateful person.

"Who are you with, don't forget that we are from the same door, and we came here together to find treasures, how can we talk to outsiders now. Wang Pengzhan was even more angry.

"I'm the right thing, not the right person. Liu Ruyan also snorted and looked at Wang Pengzhan, "Besides, we still need the help of the Heavenly Machine Daoist to get out of the desert!"

Wang Pengzhan squeezed out a mysterious smile on his face, which was even more ugly than crying. "Don't worry, I've learned all his skills, and I guarantee that we will get the treasure out of the desert safely. When the time comes, you and I will be Monopoly. ”

Speaking of this, Wang Pengzhan couldn't help laughing, as if he had really become a rich man. At this time, Tianjizi was taking Nie Yuanfeng and Long Jingtian to look for the entrance on the other side of the ancient city. The disciples walked at the front, clinging to the city wall and looking back and forth.

"Tianjizi, do you think there is really a treasure in this ancient city?" Long Jingtian always thought that this was just a legend.

"Who knows!" Tianjizi carefully observed every detail of this ancient city, "It is better to believe that it exists than to believe that it does not exist." Besides, our goal is not to find treasures, but to find the foxes. ”

Speaking of that Jia Deren, everyone suddenly had a question. Since that Jia Deren set out before everyone with the treasure map, why hadn't he arrived here yet? Could it be that he had lost his way in the desert, or was he hiding nearby and waiting for the right moment?

Wang Pengzhan pulled Liu Ruyan and walked quickly towards the south of the ancient city. Suddenly, he stopped, stretched out his hands and struggled to scrape the ground. It didn't take long for a large sand pit to be dug out of the ground, and a circular button was exposed underneath.

"Hahaha!" Wang Pengzhan laughed like a madman, "Sure enough, it is exactly the same as what is recorded in the ancient books, and the mechanism is hidden here." ”

It turned out that Wang Pengzhan had long known that there was an organ in the ancient city, and the organ was hidden in the south at noon. These are the conclusions he came to after spending several years of painstaking efforts and consulting a large number of ancient books.

Wang Pengzhan lifted the circular mechanism upward, only to hear a "creak", the ancient city wall actually cracked a gap, and it became bigger and bigger, until it was enough to drill into a person before it stopped moving.

"It turns out that you knew that the entrance was here, and you deliberately threw off the Tianji Dao to grow them. Liu Ruyan saw Wang Pengzhan's true face more and more.

"Don't talk nonsense, the treasure will belong to the two of us soon, and we will be able to be human in no time. Wang Pengzhan said this, and there was another burst of uncontrollable laughter.

Wang Pengzhan laughed so terrifyingly, like a psychopath, and like a greedy demon. Liu Ruyan couldn't help but shudder, she began to become more and more unfamiliar with the fellow who got along day and night in front of her, this was not the Wang Pengzhan in her eyes.

"Don't be in a daze, let's go!"

Wang Pengzhan pulled Liu Ruyan into the entrance. Entering the ancient city, Wang Pengzhan closed the mechanism, and the city wall was slowly restored, no different from the original.

Not long after Liu Ruyan and Wang Pengzhan entered the entrance of the ancient city, a mysterious figure walked out from behind the sand dunes not far away. He smiled smugly and walked straight towards the location where Wang Pengzhan had opened the mechanism just now.

This is the praying mantis catching cicadas and yellow finch, and a fierce battle for treasure has just begun. The mysterious man followed the method that Wang Pengzhan had just operated and easily opened the entrance to the ancient city. He let out a pore-shrinking laugh darkly, burrowing into the mysterious ancient city.

"Fight with me, you're all too tender. Upon entering the ancient city, he whispered to himself that in the dim light, his devilish face looked even more sinister. A scar lying on his left cheek like a large flesh worm is Jia Deren.

Ever since Jia Deren had stolen Tianjizi's supplies that day, he had taken the treasure map he had defrauded from Wang Pengzhan and walked in the direction of the ancient city.

According to the location of the treasure map, he came to the location of the ancient city, but there was no ancient city here, but there was only yellow sand everywhere.

"Did Wang Pengzhan, that stinky boy deceive me?" Jia Deren muttered through gritted teeth.

Jia Deren did not give up, he searched here and again, and his feet walked through an area of several kilometers. Just when he was about to despair, he suddenly noticed several figures walking towards him.

The cunning old fox immediately hid behind a hidden sand dune. When those people walked in, Jia Deren saw clearly that it was Tianjizi and Wang Pengzhan.

He thought to himself that the treasure must be nearby, otherwise Wang Pengzhan would not have come here with Tianjizi. Immediately after the dark clouds pressed down, a tornado hit, and the ancient city that had disappeared for 500 years miraculously appeared.

Jia Deren wanted to go out and find the entrance to the ancient city, but he had an idea. If you go out now, you will definitely be discovered by Wang Pengzhan, and if you don't do it, you will ruin your treasure hunt plan. It's better to hide in the shadows and reap the benefits of the fisherman. After the treasure is found, destroy Wang Pengzhan and Tianjizi.
