The door of the underground palace of the Mysterious City was opened successfully, but... Bai Yutang said that the door was opened from the inside, not because he picked the lock, so... everyone looked at each other and felt a sensation of the cold wind blowing out from the crack of the door.

At this time, it should be close to noon, but the sky in the sea of ​​ghosts was getting dark.

"Why did the Ghost Sea get dark so early?" Lin Yehuo felt that the weather was a little weird.

Zou Yue said, "There is a little different from the outside of the ghost sea. It is dark early and bright late, and it is more time tonight. Moreover, there is no moon when it is dark during the day. This is the time when sand ghost activities are the most rampant."

"Are the sand ghosts afraid of fire?" Zhan Zhao asked.

Zou Yue nodded, "I am afraid of fire and light. I rarely appear during the day. When I come out, I will hide in the sand immediately."

After a while, the sand near the stone gate was cleared, and Baiyutang opened the stone gate... In the door, there was a black hole and a path that led directly to the ground. The bottom was dark and the situation was unknown.

I took out a piece of black jade locust stone and threw it into the cave... and heard "gululu"... After a few sounds of stones hitting the wall... I didn't hear the sound of finally landing, nor did I fall into the water.

Everyone looked at each other.

Zhan Zhao frowned, "Or it would be sandy below, falling into the pile of sand, or it would be so deep that it would be so deep that it would not be heard, otherwise..."

Everyone had a thought at the same time - someone reached out to catch the stone.

"If there is really someone inside, the other party doesn't seem to object to us going in." Yin Hou smiled, "It seems to be quite welcome."

"There may be a trap below." Zou Yue frowned.

It was getting darker at this time.

"Isn't someone good? Go in and take a look." Tianzun said and then he drilled into the door. Bai Yutang grabbed him quickly and glared at him.

The Heavenly Lord squinted his eyes and looked at Bai Yutang.

Bai Yutang signaled the Heavenly Lord to come to him behind him. He took out a fire note and blew it brightly, and took the lead in entering the entrance.

There was a not-so-steep slope down the entrance. Bai Yutang walked in, and Zhan Zhao followed him in.

The Heavenly Lord also followed.

Before Zou Liang entered, he turned around and said to Zou Yue who was about to follow him, "Dad, you and Yi Yi are outside."

Zou Yue was stunned. It was not that he would refute him if he didn't let him in, but that Zou Liang called him "Dad", which made him confused and didn't know how to react for a moment.

Lin Yehuo also instructed Lin Yueyi to stay outside, signaling them to respond with the remaining sand demons and Song Jun, and looked at the door.

The last time Yin Hou walked in, glanced at the patterns that were faintly visible on the walls on both sides of the tunnel. Yin Hou frowned slightly, but he didn't say much, and followed everyone down.

Bai Yutang likes architecture and has a certain understanding of underground palaces. In addition, he has studied the mechanisms more and observed them all the way, but it was unexpected that this inclined walkway has no mechanism, but there are different patterns on both sides. The patterns look like vines lingering together, and it seems to be some kind of text, with a trace of pattern in the mess.

Zhan Zhao and others regretted it a little, just bringing Gongsun in, maybe he knew these words...

I walked a while.

There was still no mechanism or sight in the aisle, only the footsteps of the few of them, and a hint of wet and coldness.

"There seems to be a source of water below." Bai Yutang said.

Lin Yehuo asked Yin Hou behind him, "Old man, have you heard the voice?"

Everyone also looked at Mr. Yin and the Heavenly Lord.

Both of them shook their heads.

It is very quiet here, and it is easy to hear the sound, but there is absolutely no one nearby or even further away. With the internal strength of Yin Hou and Tianzun, it is impossible to hear it wrong.

So Zhan Zhao asked Bai Yutang curiously, "Are you sure the door wasn't you pried open?"

Bai Yutang nodded with certainty.

Zhan Zhao was puzzled, "What's the ability of that person who opened the door? The aisle is so long, how did he run away silently after opening the door?

At this time, a curve suddenly appeared in front of the passage that had been straight.

Bai Yutang turned around and suddenly retreated... At the same time, Zhan Zhao, who was turning around together, was quick-witted and hugged Bai Yutang and kicked him back.

The Heavenly Lord was following, and when Zhan Zhao turned around, he kicked him away. Everyone behind him also stopped and looked again... Bai Yutang grabbed the wall with one hand and stood on the edge of a broken wall with his legs...

It turned out that when I came over this turn, there was no road ahead. A large abyss appeared below, which was very dangerous.

Zhan Zhao looked down and couldn't help but stick out his tongue. The broken wall was so high that it was almost impossible to see the bottom. No wonder the black jade locust stone thrown by Bai Yutang could not hear the echo. It turned out that it had fallen.

Although this place is dangerous, it seems not a trap, because there is no path ahead in the distance, but a huge dark space, and I don’t know how big it is.

After looking around, I saw a step on the wall, extending all the way to the bottom.

However, the steps are extremely narrow and built against the wall, so they can only accommodate one person. There are no railings outside and they are very steep.

The steps surround the walls and lead to the underground.

"This underground palace was built like this. Isn't it a storage room or something below?" Tianzun was curious, "Or it is used to raise any animals?"

"Animal?" Zhan Zhao asked.

Tianzun nodded, " Raise some big bugs or something."

As soon as Tianzun finished speaking, Bai Yutang, who was about to go down the steps, stopped and looked back speechlessly at his master.

The Heavenly Lord smiled badly.

Zhan Zhao jumped gently and came to the front, which meant - he left first, he was not afraid of insects.

Everyone stopped laughing and lined up and walked down the steps.

Yin Hou was still walking at the end, and others looked down at the road, but Yin Hou looked up at the top of his head. There was no light in the underground palace, only the fire sticks and lantern Gu in the hands of everyone, there was a dim light, and nothing could be seen above his head.

However, Yin Hou didn't know what he was looking at, but just looked up with his face and looked quite focused.

"Old man." Lin Yehuo poked the Heavenly Lord who was jumping on the steps in front of him, "Is there anyone here?"

The Heavenly Lord blinked and shook his head, "It seems that there is no human words."

The answer of the Heavenly Lord caused a little doubt in everyone - what is the answer?

People say...it shouldn't be there?

Is there anyone who is not human?

Just then, a gust of wind suddenly passed.

Everyone subconsciously stopped and looked towards the top of their heads.

After a long time... with a "huh", something passed by.

This time, everyone discovered it.

"What?" Zhan Zhao frowned. There seemed to be a shadow in the darkness. According to the wind, it was quite big... but there was no sound.

"Is there something?" Zou Liang frowned and asked uncertainly.

"It seems to be there, but I don't feel the breath..." Bai Yutang looked back at Tianzun.

The Heavenly Lord raised his face and pointed toward him, looking up, with a curious expression on his face, and even looked back at Yin Hou.

Hou Yin looked at him, both of them raised their eyebrows and continued to look, as if they knew something again.

Zhan Zhao and Bai Yutang looked at each other, Lin Yehuo and Zou Liang were also a little confused - but neither of the two old men said there was danger, so it was probably not a problem, right? Could it be that the wind leaked in somewhere, or the shadow of a tree?

After waiting for a while, the movement disappeared, and there was still a piece of darkness above.

Zou Liang took out a illumination arrow and looked at everyone. What does that mean - do you want to throw it up and see it clearly?

"Wait..." Zhan Zhao reached out to stop Zou Liang, "This underground palace has not seen the light of the sky for a long time. Don't act rashly first. We are still in mid-air. If you want to throw it, wait until the bottom."

Zou Liang nodded, thinking that it made sense.

So everyone accelerated their pace and walked down.

Although this underground palace is dangerous, the stone steps are quite hard. It’s just that they walk around in circles. Everyone doesn’t know how long they have been walking, but they feel a little distressed when they finally walk. Where are they going? Are they going? Eighteen-level hell?

"Why is it so deep?" Zhan Zhao stretched out his hand and pinched Bai Yutang.

"Hiss..." Bai Yutang rubbed his arms and saw Zhan Zhao.

Zhan Zhao asked him, "It hurts?"

Bai Yutang looked at Zhan Zhao speechlessly.

"That's not a illusion... How could it be so deep?" As soon as Zhan Zhao finished speaking, everyone heard a "click".

The sound came not far away, below... it seemed to be the water surface. A piece of gravel they just kicked fell into the water?

Zhan Zhao took out a few lantern guns that Gongsun had stuffed to him before leaving, and threw them into the distance...

As the faint lights lit up, everyone realized that they had almost walked to the end. There was a large circle of flat ground below, and a pool in the middle.

As the Lantern Gu flew towards the center of the pool, everyone couldn't help but open their mouths...

I saw a huge tree in the middle of the pool.

"What kind of tree?" Lin Yehuo saw that the tree was amazingly big and lush with lush branches, so he should be alive.

"The groundwater source of the Ghost Sea is below." Zhan Zhao said, "Didn't Uncle Zou mention that there are many natural springs in the Ghost Sea, and the groundwater is very clear?"

Everyone nodded.

"How tall is this tree?" Lin Yehuo felt amazing.
