Yun Ling was very confused and wanted to solve the mystery, but now the clues were broken. Yun Ling thought about it and thought that he could go to his father to ask if the Yun family had any enemies. In this way, maybe he could find the person who wanted to poison him.

So, Yun Ling walked towards Yun Canghai's room. Along the way, Yun Ling frowned. After all, the other party came directly to the Yun family to assassinate, which was a serious threat to his life. Yun Ling must investigate thoroughly!

When he arrived in front of his father's room, Yun Ling knocked on the door, but no one responded, so Yun Ling planned to go in and wait. Yun Ling pushed open the door and walked in. Yun Canghai was a man of generous temperament, and the layout of the room was naturally simple and tidy.

Yun Ling walked to the table, found a chair and sat down. He looked around, stood up again, touched his father's weapon rack, and then took his hand back, supported his forehead, and continued to think about things. After a while, Yun Ling naturally took his hand off his forehead and put down his arm. With a "ding" sound, Yun Ling touched a mechanism!

"Creaky", a secret door slowly opened. Yun Ling looked at it, hesitated for a moment, and walked in.

"There is a secret door in my father's room. There must be a secret here. Maybe it is the secret of my being poisoned." Yun Ling thought to himself, and his feet quickened his pace.

Entering the secret door, this is a quiet place, with stone walls everywhere, and water dripping in the depths.

What hit him was the dust accumulated for many years. Yun Ling waved his hand and coughed lightly. The sound went deep into the depths. After a while, an echo came.

Yun Ling was slightly surprised. There was such a world in this secret door. Where did this secret passage lead to? Yun Ling couldn't hold back his curiosity and walked step by step into the depths of the secret passage. But the secret passage was extremely dark, and nothing could be seen clearly. There was only a dark area.

"Fire in the palm!" Yun Ling flipped his finger and a flame rose up. The secret passage suddenly lit up. Yun Ling found that the secret passage was very narrow, but Yun Ling continued to walk in.

After walking a few steps, the secret passage finally became wider, but the further he walked in, the more humid the secret passage became, and the lower the temperature became. There was a trace of water flowing down the stones on the wall. Yun Ling touched the water on the wall and found it was unusually cold. Yun Ling thought: "Is there any treasure in this secret passage? Or is there some ice layer inside? But it is too unreasonable to have ice inside." The more Yun Ling thought about it, the more he couldn't hold back his curiosity.

He continued to walk in. I don't know how long he walked. Suddenly, a light appeared in the distance. Yun Ling walked quickly and walked to a cave. Yun Ling walked out of the cave. Yun Ling was shocked by the scenery in front of him. It was all ice, and it was all ice. The light here was all reflecting the fire in Yun Ling's palm.

Yun Ling felt unusually cold and trembled all over. Yun Ling shivered and asked, "Heavenly Book, is there any treasure that can drive away the cold?"

"Ding, Master, yes, this top-grade treasure, the Fire Pill, can resist freezing attacks when placed on the body. Of course, it can also drive away the cold, and people will feel warm."

"Stop talking nonsense, as long as it is useful, quickly exchange it!"

"Ding, Master, the exchange is successful, and the current points are 14400."

Yun Ling held the Fire Pill in his hand, and it was just as the Heavenly Book said, he was not cold at once, his whole body was warm, and he also felt warmth in his hands. Yun Ling put the Fire Pill in his arms and continued to observe the ice cave.

The cave was full of ice sculptures, emitting bursts of cold air, with strange shapes, some of which were extremely sharp, and it felt dangerous and uneasy just by looking at them.

Yun Ling continued to walk forward, and as he walked, Yun Ling felt the temperature drop again. At a turn, Yun Ling saw a coffin! This coffin is made entirely of ice. In the coffin lies a white-haired old man with a crystal clear bead in his mouth. The old man's skin and hair are intact, as if he was just asleep, without any signs of decay.

Yun Ling carefully observed the old man, and as he looked at him, he felt familiar. Just as Yun Ling frowned and wondered, Yun Ling saw his own reflection in the ice. He was shocked! This old man looks so much like himself!

Yun Ling thought, is the one lying here my ancestor in this life? Thinking about it, Yun Ling quickly knelt down, kowtowed three times, and bowed. After all, he disturbed other people's peace, so he should be respectful.

After worshiping, Yun Ling stood up and carefully observed the coffin. The whole body of the coffin was made of ice, and the pattern outside the coffin was complicated. Yun Ling looked at it and felt something was wrong. There was no gap in this coffin, that is, there was no coffin lid! It seemed that the whole coffin was formed naturally. Yun Ling looked around and found a box next to the coffin.

It is engraved with: "The Life of Yun Boen"

"Yun Boen, so this ancestor is called Yun Boen." Yun Ling murmured. Yun Ling wanted to open the box, but found that he couldn't open it, so Yun Ling had to ask for help from the Book of Heaven.

"Is the Book of Heaven here? How do I open this box?" Yun Ling asked.

"Ding, Master, the Book of Heaven is here. This box is a mythical treasure of the Earth - the Bronze Sparrow Box. You need a Bronze Sparrow Key to open it. The Bronze Sparrow Key cannot be exchanged for the level of this book, and your points are far from enough."

(After the items reach the epic level, they are mythical treasures. Myths are divided into earth mythical treasures and heaven mythical treasures.)

"Hey, it seems that the road to cultivation is still long, and there is really a long way to go!" Yun Ling sighed. It seems that I can only wait until I have points in the future, and then come here to open the Bronze Sparrow Box to find out!

"No way, I can't come to this secret realm and really go back with nothing!" Yun Ling said a little discouraged.

Yun Ling looked around, and suddenly, he saw a strange ice sculpture, which had a slight color difference from other ice. If you don't look carefully, you really can't see it. Yun Ling walked closer and gently stroked the ice sculpture.

"Boom boom" Yun Ling triggered the mechanism, and an ice door slowly opened, and a more chilling cold air floated out.

"Tian Shu, this fire pill doesn't feel warm anymore, exchange it for another fire pill." Yun Ling said lightly.

"Ding, master, the exchange is successful, and the current points are 13400."

Yun Ling put the fire pill in his arms again, and then walked towards the ice door. After entering the door, there was a bead placed at the innermost!

Yun Ling stepped forward quickly and looked at the treasure carefully. At this time, Tian Shu couldn't help but said.

"This is the Red Dan Divine Pearl! It has the magical effect of rebirth, and the most important thing is that it can make you unscathed when you experience the heavenly tribulation!"

"Heavenly tribulation? When will you experience the heavenly tribulation?" Yun Ling asked in confusion.

"After the martial arts master, the venerable, the human venerable, and the heavenly venerable all need to experience the heavenly tribulation before they can break through." Tianshu explained.

"Then this is really a treasure! Collect it, collect it." Yun Ling put the red dan divine bead into the spirit bag.

"Okay, this trip is worth it. Go back to the city!" Yun Ling said.

After that, Yun Ling crushed the instant talisman and returned to his father Yun Canghai's room.

(The instant talisman can be instantly sent to any place within 10 kilometers, but it must be a place that has been visited and the approximate location is known.)

Back in the room, Yun Ling sat down and took a sip of tea, and destroyed the two fire pills that had lost their effectiveness. Just as he was about to get a golden leaf - the leaf of heaven, a sound of footsteps sounded outside the door.
