Chapter 739 Another Broken Sword

The Demon King's lair is located at the bottom of a deep pool. It is a natural cave. The cave walls are inlaid with gems and glow with a faint yellow light, which is not too dark.

After Hei Feng entered here, he immediately started searching in the cave.

"It should be here, why can't I find it?"

Heifeng searched for a long time and frowned. He could clearly feel that the treasure was here, but he couldn't find it, and he couldn't help but feel a little anxious.

"Are you sure you're here?"

Yun Yi also released his senses, but he didn't find anything special here at all. He didn't know how Heifeng sensed it.

"Of course, look."

As Heifeng spoke, he spat out a broken sword, which he found in the Peace Villa before, but he didn't say anything at that time.

If he hadn't taken it out now, Yun Yi would have almost forgotten about this matter.

Now Heifeng took out the broken sword, which once again aroused Yun Yi's curiosity. What on earth is this thing that can make Heifeng pay so much attention to it.

As soon as the broken sword appeared, it immediately hit the stone wall in front of it. The imaginary collision sound did not appear, and the broken sword was seen to have penetrated directly.

"This is?"

Both of them were shocked, and immediately stepped forward to observe, and found that there was a spatial barrier here, blocking the depth of perception.

"Yes, only the space barrier can block the detection of our souls. Now it has become more developed."

Heifeng immediately beamed. The fact that the Demon Emperor valued him so much and even specially disguised it meant that there must be a lot of good things in it.

"But how to break through this space barrier?"

Yun Yi was pleasantly surprised but at the same time he couldn't help but feel a little worried. This space barrier was obviously set up by the demon emperor, and he had a connection with the demon emperor.

Once they forcefully break through, they will inevitably be discovered, and by then, their situation will be passive.

"This won't trouble me, come on."

Heifeng smiled, waved his hand, and a stream of light flew out from the space barrier and landed in front of him. It was the broken sword.

Under the control of Heifeng, the broken sword lightly swiped on the space barrier, directly creating a gap without causing any fluctuation.

Yun Yi was surprised, what kind of grade was this broken sword? It could actually cut through the space barrier silently, which even the Jiuji Sword couldn't do.

"Walk!"

After Heifeng finished speaking, he got in directly, followed closely by Yun Yi.

After entering, they found that this place turned out to be a huge space about a hundred meters in radius, with a gray area inside.

From what Yun Yi and the others knew, this space was not an ordinary place, but an independent space opened up by a powerful person with great means.

This is a bit overbearing. Such a method can only be used by masters above the Spirit Master.

"Look."

Black Wind seemed to have discovered something, pointing forward and shouting.

Yun Yi looked along and saw half a pale skeleton not far away, exuding strong pressure.

"Is this a dragon bone?"

Yun Yi's eyes widened, because the skeleton felt like a dragon to him, with a pair of dragon horns growing on its head.

"It's not a dragon bone, it's a dragon bone. No wonder the Demon Emperor has such an opportunity. Xiao Yunzi, put it away quickly, and when you break through the Spirit Emperor, integrate it into the Jiuji Sword. It can greatly improve the strength of the Jiuji Sword. Power, if you are lucky, you can also give birth to dragon power and suppress all directions. "

Heifeng clicked his tongue and marveled. Although this dragon bone was not a real dragon bone, it was still a very rare treasure.

The dragon takes one step further and becomes a real dragon.

The reason why the demon emperor was able to turn into a dragon was probably due to this bone. After all, given its condition, it was basically impossible to transform into a dragon without a great chance.

Unfortunately, he only refined half of it before they interrupted it, and the remaining half of the dragon bone could not help him complete his transformation.

However, this was a bargain for them.

"good!"

Yun Yi was not polite and directly put away the half of the dragon bone. The Jiuji Sword was his natal weapon. As it became stronger, his own strength would naturally increase.

"By the way, where is the baby you are looking for?"

Yun Yi turned his attention to Heifeng again. This guy wanted to get something even if he provoked the Demon Emperor. How could he not be curious.

"This is it."

Heifeng waved his hand, and another broken sword appeared in his hand. It seemed to be one piece with the previous one.

"What kind of soldier is this?"

Yun Yi still couldn't help but ask, being able to cut through the space barrier silently and being so valued by Heifeng must not be ordinary.

"Don't ask, you just need to know that this thing is very powerful, and only I can use it now."

Black Wind didn't say much.

"All right."

Yun Yi didn't ask any more questions and turned his attention elsewhere.

This can be said to be the Demon King's treasure house. There are many good things in it, including all kinds of soldiers, a wide variety of medicinal materials, and a large number of spiritual stones and ores, all of which are priceless.

After entering Debao Mountain, how could Yun Yi come back empty-handed, especially the medicinal materials and spiritual stones?

As for Black Wind, he didn't want anything. He was already satisfied if he could get the broken sword.

"Let's go."

Yun Yi said with satisfaction that he had already plundered everything here. The profit this time was so great that he would not even have to worry about spiritual stones and medicinal materials for a long time in the future.

"etc."

Hei Feng was about to leave, but suddenly he seemed to think of something and stopped again.

A space of this size requires at least a fifth-level spiritual master to open it up. If it is just used to store some sundries, it would be overkill.

After all, for a master at the spiritual level, things like dragon bones are almost the same as garbage. Only the bones of a true dragon can penetrate his eyes.

So, he let go of his senses, thoroughly explored the entire space, and finally discovered something strange in an inconspicuous place.

As soon as his body moved, Hei Feng came here immediately.

There was a futon in this place, which looked ordinary, but it was precisely because it was so ordinary that it caught Black Wind's attention.

This is like a beggar mixed in among a group of dignitaries, which is indescribably awkward.

"Xiao Yunzi, sit on it and try it and see what the difference is."

Heifeng said that although he was not sure whether his idea was right, his feeling told him that there might be some secret hidden in it.

Yun Yi also followed over and sat up after hearing the sound.

In an instant, Black Wind disappeared, and even he himself disappeared, leaving only countless thin lines and dots.

Yun Yi was a master of the Spirit King and had already been exposed to space, so he immediately realized that these points were space nodes, but it was the first time he saw those lines.

It seemed that there was a voice in the dark telling him that this was space.
