Although the female Taoist Xie Ying hoped that they would stay in Yuexia Villa for the time being, Li Zhen and Di Yan insisted on returning to the inn.

When they returned to the inn, it was already two o'clock. Li Zhen sent Di Yan to her door and smiled at her, "Get your energy well, let's go to the underground palace to take a adventure tomorrow night."

Di Yan was a little worried, "Brother Li, I always feel that things are not that simple."

"I also have many confusions that cannot be solved, but at least they don't want to kill us. All the doubts will be resolved until tomorrow night. I'm too lazy to think too much, so let's take a break!"

Di Yan nodded silently, "You can rest well, too."

She slowly closed the door. Li Zhen took a few steps, stopped hesitantly, and turned around and stared at her door. The doors of Di Yan slowly opened again. The two looked at each other, and Di Yan glared at him fiercely.

Li Zhen returned to his room and got into the quilt. He was already extremely tired and didn't even take off his shoes, so he fell asleep.

......

Li Zhen slept until noon the next day. When he slowly opened his eyes, he found that Di Yan was sitting beside him. She had changed back to women's clothing, wearing a light green robe, a pomegranate silk skirt, her arms were wrapped around red silk, and a double-ring bun was combed, and a jade hairpin was inserted diagonally. She looked beautiful and her skin was as bright as jade.

Seeing her holding needles and thread in her hand, she was sewing a headscarf for herself with all her concentration. Li Zhen couldn't help but smile and said, "You can still do needles and threads?"

Di Yan was startled by him, quickly took the needle and thread behind him, and said coquettishly: "Are you lazy guy finally awake?"

Li Zhen raised his arms high and stretched his waist long. He found that his shoes and socks were taken off. He said a little embarrassedly: "I was too sleepy last night. I fell asleep when I fell down and didn't bother to take off my shoes."

"Yes! I didn't bother to take off my shoes, and even the door was locked. I just hoped that some thief would come in and kill you with one knife."

Li Zhen scratched his head and smiled, "I guess the little thief doesn't like me, a poor man. You might as well just pretend to be a little thief and touch it in."

Di Yan blushed and poked him hard with a needle, "Get up quickly, I'll faint from hunger when you are noon!"

Li Zhen seemed to think that he had said something wrong, so he jumped up embarrassedly and put on his shoes randomly, "I'll go and wash!" He pulled his feet downstairs, and the footsteps ran thud.

Di Yan sighed, put away the needle and thread, and then tidied up the bed for him, while whispering: "You can sleep until noon. No wonder his eldest sister always calls him lazy. She is so lazy."

"I'm fine!"

Li Zhen had washed his face and looked refreshed. Seeing that Di Yan had already cleaned up his room, he smiled and said, "Let's go for lunch, I'll treat you to roast lamb legs."

"Then what?"

"Then we go to Tai Chi Palace to take a step, first find Ziyun Pavilion, then see if there are any patrols or something, and prepare for the evening."

Di Yan didn't say anything, she felt a little disappointed. In fact, she wanted to go to Qujiangchi.

.........

Tai Chi Palace is located in the north of Chang'an City. When Emperor Wen of Sui ruled, it was the political center of the Great Sui Dynasty and was first called Daxing Palace.

After the establishment of the Li Tang Dynasty, the Tai Chi Palace became the political center of the monarchs of the Tang Dynasty. The famous "Xuanwumen Incident" occurred in the Xuanwumen north of the Tai Chi Palace.

Since Emperor Gaozong of Tang Dynasty Li Zhi ascended the throne, the Tang Dynasty began to build a new palace - the Daming Palace, and the Tai Chi Palace gradually fell into the curtain of history and became the residence of some old palace concubines.

In the era of Wu Ze's Catholic rule, the entire Chang'an was neglected. In order to get rid of the control of the Guanlong nobles over the Tang Dynasty, Wu Zetian resolutely decided to move the capital to Luoyang. The capital of the god Luoyang flourished. Chang'an was like a concubine who was inscribed into a cold palace, gradually deviating from the political and economic center of the Tang Dynasty.

The Tai Chi Palace became the yellow flower of the past. Almost all the palace supplies were transported to Luoyang, and the palace maids and eunuchs also moved to Luotaichu Palace. The Tai Chi Palace was filled with huge empty buildings, no one lived in or managed, with wild grass growing and snakes and rats forming nests.

However, there are still a thousand troops stationed in Tai Chi Palace. They stationed at the palace gates and patrolled the palace to prevent ordinary people from entering the palace at will, and safeguarded the dignity of the Tang Dynasty.

But for Li Zhen and Di Yan, who are skilled in martial arts, the army's protection is meaningless at all. At night, the two sneaked into Tai Chi Palace from near Xuanwu Gate to the north. After passing through a long corridor, they entered the bedroom area of ​​Tai Chi Palace.

Li Zhen and Di Yan both changed into black clothes and night clothes, wearing long swords, Li Zhen was arching on his back, and carrying a heavy and long bag in his hand.

They had already stepped over the spot during the day and were very familiar with the road to Ziyun Pavilion. The two of them moved quickly and climbed up a mountain pavilion. The whole picture of the Tai Chi harem appeared in front of them.

To the north of the bedroom is the Houyuan. There are several large pools in the middle and west of the garden, called East, West, and South China Sea Ponds. There are some garden-like temples around the three pools. There is also a group of mountain pond courtyards in the northwest corner. At the foot of the mountain is the Qianbu Lounge, which runs across the east and west and leads directly to Ziyun Pavilion.

In the east of the Dachi, there are a series of pavilions such as Lingyan Pavilion, Gongchen Pavilion, Ziyun Pavilion, Ningyun Pavilion, etc., and the Ziyun Pavilion they are going to be located in it.

Di Yan stared around for a moment and said, "Brother Li, it's a bit strange tonight. Have you noticed that there are no patrol soldiers in Tai Chi Palace?"

Li Zhen sneered and said, "This should be Wei Tuaner's credit. She paved the way to enter the palace for Yupinlong, but in the end it made us cheaper."

Di Yan also felt it made sense. She frowned slightly and said, "Can the female Taoist priest named Xie stop the fish-pinlong?"

Li Zhen nodded, "The underground palace has been opened for too short and very dangerous. If there is interference from others, it will inevitably fail. I think the female Taoist nun knows in her heart that she will do her best to stop the fish-picking dragon."

Di Yan had no good feelings for the female Taoist nun. She didn't want to listen anymore, so she pulled Li Zhen, "Time is coming soon, let's go!"

The two ran down the mountain pavilion and ran along the Qianbuluo corridor toward Ziyun Pavilion located on the northeast bank of Haichi.

.........

Tonight, there were indeed no soldiers defending the Tai Chi Palace. Wei Tuaner's secret orders played a role. A thousand troops were changed to garrison the Daming Palace. There was no one in the huge Tai Chi Palace.

At this time, a group of black shadows quickly crossed Xi Neiyuan and rushed towards Xuanwu Gate. The group of people were the ten subordinates led by Yu Pinlong. They arrived in Chang'an at noon today and made some necessary preparations. They prepared ladder parts that could be temporarily put into a long ladder.

Yu Pinlong was also very nervous. If the mission failed today, Wei Tuaner would never spare him easily. He understood Wei Tuaner's methods and was cruel and vicious. Li Dan's Concubine Liu and Concubine Dou were tragically harmed by her, and even the bones were not left. Thinking of Wei Tuaner's ruthlessness, his heart trembled.

The royal gardens of Xineiyuan, Sui and Tang dynasties, were barren for many years and had already grown in bushes. The aquatic reeds grew taller than people. When Yu Pinlong and his men were about to cross a small river, a scream suddenly came from behind.

When Yupinlong turned around, he saw his subordinates falling into the grass. In the blink of an eye, half of the ten subordinates disappeared. Yupinlong was shocked and drew his sword and shouted urgently, "Leave the grass!"

His men were also panicked. Before they could react, countless black shadows rushed out of the grass, dozens of people pressed his men one after another. Snow-bright daggers stabbed into the heart, and screams came from the dark night.

The fish-picking dragon then saw clearly that it was not a beast and a poisonous snake, but an ambush. He reacted very quickly and turned around and fled.

At this time, an arrow suddenly shot into his thigh, and the fish dragon fell to the ground, but the survival of the person still made him get up desperately and stumble and run northeastward.

A warrior raised his military crossbow and aimed at his back, but Wu Yinghong reached out to press the crossbow, "A Gu has an order to save his life!"

Wu Yinghong watched the fish dragon escape, and he turned around and stared at the depths of Tai Chi Palace.

Xie Daogu didn't allow them to interfere in Li Zhen's actions, which made him a little puzzled. If they went to help, wouldn't it be more powerful? But he didn't dare to disobey the order, so he waved his hand and said, "Let's go!"

He led more than 30 subordinates to quickly evacuate Xi Neiyuan, and left ten corpses in the grass.

.........

Ziyun Pavilion was called Vajra Pavilion during the Sui Dynasty, which was related to Emperor Wen of Sui’s devout Buddhism. The original purpose was to worship Buddha treasures. After Li Yuan, the Emperor Gaozu of Tang Dynasty, he changed the Vajra Pavilion to Ziyun Pavilion.

Since purple clouds are more than 20 feet high, it is the tallest building in Tai Chi Palace. Standing on the top of the pavilion, it seems to be directly up the sky of purple clouds, Li Yuan changed his purpose and used it to view the sky statue at night, while the underground palace was renamed the Zangxi Palace.

After Li Yuan's death, Emperor Taizong Li Shimin put the seal used by his father into Yu Linglong and put it into the seal palace.

After Li Shimin passed away, Emperor Gaozong Li Zhi put the seal used by his father into Yu Linglong and put it into the seal palace, which almost became the tradition of the Emperors of the Tang Dynasty.

But this tradition stopped abruptly when Emperor Gaozong of Tang Dynasty. After the old palace maid A'e, who was in charge of the key, passed away mysteriously, there was a missing key to opening the underground palace, which made it impossible for the underground palace to be opened.

More importantly, Wu Zetian did not want to inherit this tradition, but sealed all the seals used by her husband Gaozong into Qianling Mausoleum, and this unopenable underground palace was gradually forgotten.

However, Yu Wen Kai, the master of designing this underground palace, considered the loss of the key and made a clever design. Every seven years, the underground palace has the opportunity to open automatically.

Tonight, Li Zhen’s mission is to take out Yu Linglong, who has two generations of emperor seals, from the underground palace.

Li Zhen used the iron key given by Xie Ying to open a stone door under Ziyun Pavilion and slowly pushed it open. The stone door was only six feet high and four feet wide. Behind the stone door was a stone corridor about two feet deep, which directly led to the heart of Ziyun Pavilion.

The two of them waited for a while in front of the stone gate before lit the torch and slowly walked into the corridor. Li Zhen lowered his head, pointed to the torch with one hand and held the sword with the other, and walked forward carefully step by step.

Di Yan followed him, but gently stroked the stone walls on both sides. The stone walls on both sides were carved with patterns of various Buddhist stories, and the patterns were vivid, implying the original purpose of this pavilion.

In just a moment, the two walked into Ziyun Pavilion's ventricle. When they looked up, they both screamed in surprise.
