All Heavens Check in from Douluo

While speaking, Yun Feng couldn't help but think of the Heavenly Emperor's Treasure House in the Dead Marsh, which existed on the ancient trees of unknown ages and was guarded by the divine beast Yellow Bird.

Obviously, the Treasure House of the Emperor of Heaven could not be created by a cultivator in the world of Jade Immortals.

Even the giants of good and evil in the world of Jade Immortals, and even Linglong, the witch in southern Xinjiang who created the beast god, do not have the ability to create the treasure house of the emperor of heaven!

Obviously, the treasure house of the Heavenly Emperor was probably left in the human world by a terrifying existence in the God Realm, one of the six realms of Jade Immortals!

"I must go to the Heavenly Emperor's Treasure House if I have time in the future."

Yun Feng put away Li Po, and murmured in his heart.

Originally, he had no intention of entering the Heavenly Emperor's Treasure House. After all, for him, the only valuable thing in the Heavenly Emperor's Treasure House was the third volume of Tianshu.

However, now that he has practiced all the heavenly books in the system-improved version, the third volume of heavenly books hidden in the Heavenly Emperor's treasury is of no use to him.

But after confirming the existence of the ghost world, Yunfeng had no choice but to go to the treasure house of the Heavenly Emperor.

If his deduction is correct, the Heavenly Emperor's Treasure House is likely to be related to the God Realm. If he can use this to learn more about the God Realm, it will also be of great help to him in the world of Jade Immortals.

"Is there a passage into the ghost world in the forbidden area?"

Bi Yao didn't know what Yun Feng was thinking, after hearing Yun Feng's words, Bi Yao was startled at first, and then anticipation appeared on his face.

"Brother Yun, let's quickly search to see if we can find a passage to the ghost world!"

Baguio looked at Yunfeng with anticipation.

"Don't think about it, even if you find the passage to the ghost world, I can't take you in."

Yun Feng reached out and tapped Bi Yao on the head, and said angrily: "Your cultivation base is too low, if I take you into the passage of the ghost world, in case of danger, I may not be able to distract you and take care of you."

Baguio couldn't help feeling disappointed when she heard the words, but she also knew that Yunfeng was telling the truth.

Although her strength is considered top-notch compared with her peers, the gap between her and Yunfeng is as big as Tianyuan.

The ghost world is one of the six worlds recorded in ancient books, and there must be many powerful and terrifying existences in it.

Even Yun Feng may not be sure that he can retreat after entering the ghost world. If she stays with Yun Feng, not only will he not be able to provide Yun Feng with any help, but on the contrary, Yun Feng will be in danger because he is distracted from taking care of her.

It's just that although Bi Yao is talented, she still has a childish temper after all. Even if she knows that Yun Feng is telling the truth, she will inevitably feel disappointed.

"Don't worry, even if I find the passage to the ghost world, I won't go to the ghost world in a short time."

Seeing Bi Yao's disappointed expression, Yun Feng shook his head helplessly, and comforted him: "As long as you can improve your strength as soon as possible, I will consider taking you to the ghost world with me in the future."

Once he entered the ghost world, Yunfeng couldn't guarantee that he would be able to come back in a short time. Now that the tragedy in Caomiao Village is approaching, how could Yunfeng leave for a long time at this time?

Therefore, in a short period of time, even if he found a passage to the ghost world, Yun Feng would not choose to enter the ghost world.

Unless he can get a treasure from the treasure chest that can travel between the human world and the ghost world in Jade Immortal World at will!

Hearing Yun Feng's words, a smile reappeared on Bi Yao's face, and said solemnly: "Brother Yun, don't worry, I will definitely work hard!"

Yun Feng didn't speak when he heard the words, his eyes swept around, and finally fixed on a mountain wall.

There are densely packed characters engraved on the mountain wall, although the distance is far, Yun Feng can still easily recognize those characters.

"Heaven and earth are not benevolent, and treat everything as a straw dog."

Baguio also saw the writing on the mountain wall, read it softly, and then suddenly said: "This should be the second volume of the Heavenly Book that Uncle Xiaoqi said!"

"That's right," Yun Feng nodded, but he seemed a little absent-minded.

According to the two powerful ghost kings who guarded the entrance of the forbidden area before, the forbidden area of ​​the ghost king's sect is full of dangers, but since he and Baguio entered the forbidden area of ​​the ghost king's sect, he has never found anything abnormal except for the ghost ghost. .

"Brother Yun, is there something wrong?"

Baguio quickly discovered Yunfeng's abnormality and couldn't help asking.

"I'm just a little surprised. According to your two uncles, the forbidden area of ​​the Ghost King should be very dangerous, but we have been in the forbidden area for so long, but nothing happened..."

Yun Feng frowned, and said softly: "I'm worried if there's something I've missed."

As soon as Yun Feng finished speaking, the ground under his feet suddenly shook, and several black shadows rushed out from the ground and rushed towards Yun Feng.

The black shadow moved extremely fast, and even with Yun Feng's strength, he could barely react, covering his whole body with true essence, forming a set of true essence armor on his body.

A few black shadows collided with Yun Feng's true essence armor, and instantly tore the true essence armor to pieces, but those black shadows were also shaken and flew upside down, hitting the ground.

Only then did Yun Feng see the true colors of those black shadows.

They were a few mice the size of a lynx, and there were countless pustules on those mice. Inside each pustule was a hideous and distorted grimace, which looked very permeable.

"What is this!"

Seeing the terrifying mouse, Bi Yao shrank into Yun Feng's arms, trembling.

Although Baguio's courage is not small, the visual impact of this weird thing on her is really too big.

Not to mention Baguio, even Yun Feng was secretly startled when he saw the faces of those mice clearly.

This is the first time he has seen such a disgusting thing!

Sweeping his gaze over the mice, Yun Feng blocked Bi Yao's eyes with his left hand, and waved Li Po directly with his right hand.

Sword Qi gushed out and chopped towards the mice.

Those rats were just disgusting in appearance, and their own strength was not strong. Facing the overwhelming sword energy that Yunfeng slashed out, those rats with disgusting shapes couldn't hold on for even a moment, and were directly crushed by the sword energy!

[The host kills the soul-eating rats in the world of Zhu Xian, and the energy of heaven +100]

Hearing the system prompt sounding in his ear, Yun Feng couldn't help curling his lips.

Looking at the shape of the Soul-Eating Rat, he thought it was a big guy, but the sum of these several Soul-Eating Rats only provided him with 100 points of Heavenly Dao Energy.

Shaking his head in disappointment, Yun Feng then removed his left hand that blocked Baguio's eyes.

"Brother Yun, is it resolved?"

Baguio opened his eyes cautiously, but did not dare to look around.

The appearance of the Soul Eater is really disgusting, she really doesn't want to see more.

"It's okay," Yun Feng smiled, and walked directly towards the stone wall engraved with the second volume of the Book of Heaven.

A lot of the sword energy he cut just now landed on the stone wall engraved with the second volume of the Heavenly Book, and it was precisely because of this that he discovered something interesting.
