Along the spatial passage, Yun Hong followed Bai Xiao to a dark place.

The place was surrounded by a hazy purple mist, and it was difficult to perceive the border, except for a stone platform in the center that attracted Yunhong's attention.

"This stone platform?" Yun Hong stared at the stone platform that was as white as jade and about three zhang in diameter, and the aura emitted was full of mystery, making him feel unfathomable.

"This stone platform was left by the old master a long time ago. Bai Xiao said in a deep voice: "It has the effect of calming the mind, and it can also assist in enlightenment, and the value alone is close to a superb Taoist weapon." ”

"Really?" Yun Hong's eyes lit up.

Both the Town Boundary Tower and the Purple Cloud Realm will leave the Changfeng World.

Although there are a lot of treasures on Yun Hong's body, all of them are worth hundreds of thousands of spirit crystals, and they can be exchanged for one or two top-grade Dao weapons.

And his cultivation needs are huge, and he is very poor!

"Don't think about it, this stone platform and I are one, and it is the core of the magic weapon of the cave. Bai Xiao glanced at Yun Hong: "So, don't want to sell it." ”

The corners of Yun Hong's mouth twitched, this Bai Xiao really didn't give himself face.

But.

If you can't dismantle it, you can't dismantle it, just one cave heaven core value is so high, the value of the entire cave heaven magic weapon must be terrifying, no wonder Bai Xiao said that she is the most important treasure left by Bai Jun.

Wrong.

Yun Hong's mind flashed with inspiration, and he couldn't help but say, "Bai Xiao, you just said that this was left by the old master?"

"Who is the old master?" Yun Hong stared at Bai Xiao.

Bai Xiao's previous title for Bai Jun has always been 'master', not 'old master'.

"Let's make a heavenly oath first!" Bai Xiao flipped his palm, and a dark green token suddenly appeared in his palm, the breath was very weak, but there was a faint meaning of vastness.

"This token?" Yun Hong frowned slightly.

"It's an oath order. Bai Xiao said: "This is the old master's order, you can look at the content of the oath and then decide whether to abide by it." ”

Bai Xiao waved his hand, and suddenly, a phantom appeared in the air, and a large number of words were engraved on the phantom, which was the oath that Yunhong wanted to make.

Yun Hong glanced at it, and immediately understood.

He immediately put his hand on the dark green token, and a vast invisible wave descended directly, completely enveloping Yunhong.

"I, Yun Hong, swear under the witness of the gods of the Eastern Netherworld and the Heavenly Dao...... Yun Hong recited a large part of the oath.

The oath is long.

But there is only one core content, the person who inherits the 'Beijue Cave Heaven' must be a living creature in the Changfeng World.

Moreover, before surviving the Heavenly Tribulation at the latest, the magic weapon of the same level must be left in the Changfeng World and left to the descendants of the clan.

Once the oath is made, the cause and effect are completed.

It cannot be violated.

"Whew!" Yun Hong opened his eyes, feeling another layer of shackles binding him in the dark.

This shackle is the bondage of the cause and effect of the vow.

If he has not been able to cultivate the Yuan Shen, he will not be hurt too much if he violates it, and the Yuan Shen has not been placed in the Heavenly Dao (Heaven and Earth Origin), at most he has only cut off the path of cultivation.

However, if you cultivate the Yuan Shen in the future, once you violate the oath of the Heavenly Dao, you will inevitably be punished by the Heavenly Dao and those who witness the great power, and when you cross the Heavenly Tribulation, you will be full of demons, and it is almost impossible to become an immortal and a god again.

Right now, this shackle won't hinder his cultivation, but when he cultivates to the world realm, it will become an obstacle to him.

"This Heavenly Magic Weapon is called Beijue?" Yun Hong couldn't help but say, "It was left by Beijue True Monarch?"

He had made an oath just now, and he had learned a great deal of information.

"Yes. Bai Xiao nodded and said: "Beijue Zhenjun, is my old master, he is a monk born in the Changfeng World millions of years ago, after he failed to cross the Heavenly Tribulation, he left many treasures in the cave sky, leaving a legacy for the descendants of Changfeng." ”

"It's just that in the next million years, the Changfeng world has not been able to give birth to outstanding people, and no one can get the inheritance of the old master. ”

"It wasn't until the master Bai Jun that he finally completed the old master's test and inherited the Beijue Cave Heaven. ”

The master also made an oath. Bai Xiao said: "So, when the Changfeng World was suppressed, the master Bai Jun was worried that he would not be able to complete the oath in the future, so he finally kept me in the Changfeng World." ”

Yun Hong suddenly.

He was very strange before, Bai Jun was only in the realm of all things at the beginning, why could he have such a precious 'Cave Heaven Magic Weapon'?

Moreover, even if you want to leave a legacy, you can open up a small world to store it, such as the Chengyang Secret Realm, the Black Dragon Secret Realm, etc., so why do you need to leave such an important Cave Heaven magic weapon?

Now, the truth is out.

At the beginning, Bai Jun inherited the inheritance of the 'Beijue True Monarch', and I am afraid that he also made a heavenly vow similar to Yunhong today, and he must give the 'Changfeng One Pulse' in the future.

Sixty thousand years ago, the world of Changfeng changed greatly, and Bai Jun was worried that he would never return, and he would be bound by an oath in the future.

Therefore, he simply left the 'Beijue Cave Heaven', even if he could not return to the Changfeng World in the future, he could be regarded as having fulfilled this oath.

"You inherit the inheritance today, and if you have the ability in the future, you will also have to give back to Changfeng. Bai Xiao said.

"I understand. Yun Hong nodded.

"Well, sit on the jade platform, it is the core of the cave sky, refining it, you will be able to control the entire cave sky. Bai Xiao said in a deep voice.

Yun Hong took a step forward and sat on the white jade platform.

Sit down.

Then he felt that his impetuous mind was quiet, as if the whole world was quiet, quiet!

Some evil thoughts and distracting thoughts that originally needed to be deliberately suppressed have all disappeared.

In a short period of time.

Even the speed of the divine soul is several percent faster, and in this state, whether it is cultivation or enlightenment, it is more relaxed.

"It is worthy of the treasure left by Beijue Zhenjun. Yun Hong said secretly, and as soon as his mind moved, a stream of true yuan infiltrated into the stone platform and began to refine.

It was not as difficult as Yunhong imagined.

On the contrary, it is extremely smooth.

In less than ten breaths, half of the entire stone platform had been refined.

This surprised Yunhong.

At the beginning, he was refining the 'Town Boundary Building', but it took several hours to barely imprint the Divine Soul Imprint.

And this 'Beijue Cave Heaven' is at least ten times more precious and powerful than the Town Boundary Tower, and it stands to reason that even if it is refined for ten days and half a month, it is normal.

"Bai Xiao, are you helping me?" Yun Hong looked at Bai Xiao who was standing not far away.

"Yes, I didn't resist you, I'm not an ordinary Dao weapon, if I don't want to, you won't be able to refine me with your strength!" Bai Xiao smiled: "Hurry up!"

"Hmm. Yun Hong nodded lightly, calming down and refining with all his might.

Time passes......

In less than a quarter of an hour, Yun Hong had completely refined the stone platform and initially controlled the entire cave sky.

"Dongtian is the real world. ”

"Is that what it feels like to be in control of the real world?"

Yun Hong closed his eyes, he sat on the stone platform, although his mind sensed a huge cave in the sky.

The world that spans thousands of miles, the dark treasure space, and the core central hall...... Everywhere, he is in perfect control.

Similarly, within the Cave Heaven, he was able to mobilize the power of the entire Cave Heaven to suppress and kill any creature he wanted to deal with.

In the cave sky, Yun Hong is the god and the master!

"Whew!" Yun Hong opened his eyes.

"Met the hosts. Bai Xiao saluted respectfully.

"Bai Xiao, it doesn't have to be like this. Yun Hong said in a deep voice.

"How I treated my master in the past, that was in the past. Bai Xiao said respectfully: "From today onwards, you are my new master." ”

After refining the entire cave sky, Bai Xiao and Yun Hong also really got close, this is from her heart.

"Hmm. Yun Hong was slightly helpless, he naturally understood in his heart.

This is the special spirit of the puppet and the spirit of the magic weapon, no matter what their relationship with you is, once they are refined, they will be absolutely loyal to their master.

"Please come here, those two!" Yun Hong said softly.

As the owner of the Cave Heaven magic weapon, he was naturally able to sense the two special beings in the Cave Heaven.
