"Yes, I promise. Ling Feng thought for a moment, and then replied, if it weren't for the fear that he would have doubts, he would have agreed when he heard this old guy say this.

Although the Yuan Spirit Brand is the most difficult means of restricting others in the world, unless the Yuan Spirit level is higher than the opponent's Yuan Spirit, there is no way to crack it at all.

But this method not only did not have any danger for Ling Feng, who had mastered the "Soul Devouring Technique", but it was of great benefit.

Of course, he will not refuse this kind of benefit sent to the door.

"Good. Ao Tian also sneered in his heart, he didn't know the existence of the "Soul Devouring Technique", otherwise, he would not have used such a stupid method to kill him.

At this moment, he was a little proud, and he was ready to take Ling Feng back to the Dragon Clan after getting the Great Void Sutra, but he only said that he would not kill him, and he did not say that he would let him go.

Even if this kid has any small means, with the Yuan Ling brand, he is not afraid.

Then, a purple light flashed from the center of his eyebrow, and then a purple spear shot out from the center of his eyebrow, levitating in front of him.

"Purple Yuan Spirit!" Ling Feng's eyes lit up, now, his Yuan Spirit had reached blue, if he could devour a wisp of purple Yuan Spirit, maybe he would be able to make it advance again and reach dark blue.

In this way, it won't be long before it can advance to the purple primordial spirit that only needs to have a king rank.

"Don't resist. Ao Tian reminded him, and then a purple light shot out from the purple spear, which directly sank into Ling Feng's eyebrows, and the next moment, Ling Feng felt that there was an extra purple spirit in his deep sea.

Ling Feng endured the thought of swallowing it and looked up at Ao Tian, at this time, he had also taken the purple primordial spirit back into his divine sea, and an imperceptible smile appeared on his face.

"Go, go to the Endless Desert. Ao Tian couldn't wait to find the Great Void Sutra, and as he spoke, he grabbed Ling Feng, and with a flash of his figure, he appeared directly in the Colin Oasis in the endless desert.

This is the power of comprehending the body of the void, and a single thought can travel to wherever you want to go.

Seeing that familiar environment, a smile appeared on Ling Feng's face, and he immediately released his divine thoughts to contact Niu Lao, but what he didn't expect was that Niu Lao didn't respond.

Just when he was wondering, Niu Lao's voice came from his head: "Little guy, you came just in time, come to me." ”

"What's wrong?" Ling Feng didn't know why, especially since he heard a little anxiety from Niu Lao's voice, you must know that Niu Lao is a saint-level powerhouse, what can make him feel anxious.

"I don't have time to explain to you now, I'm at the critical juncture of merging my flesh now, you should come here as soon as possible. After saying that, Niu Lao cut off contact with Ling Feng.

And he wanted to ask, but his divine thoughts were not as perverted as Niu Lao, and they could cover the entire endless desert, so he had no choice but to give up temporarily.

It's just that he still can't figure out what could make Niu Laodu so anxious.

Even if he was fusing his physical body, it was still in the ancient tree of life, and with such a heaven and earth alien guardian, it was impossible for anyone to cause harm to him.

If someone can really do this, what's the use of going over by themselves.

But no matter what, Niu Lao is kind to himself, and no matter how difficult it is, he can't sit idly by.

It's just that what makes him depressed is that now that Ao Tian is following him closely, it is impossible to escape under this guy's nose.

"How is that good...... Hey, yes. Suddenly, an idea flashed through his mind.

"Boy, I warn you, don't try to play any tricks on me, don't forget, you have my Yuan Spirit Mark in your Divine Sea. Ao Tian was stunned when he saw him here, thinking that he was using his brain, and immediately reminded.

"How dare I, I'm just thinking about which path to take. Ling Feng hurriedly got along with an excuse.

"What, there are still two ways to fail?" Ao Tian was stunned for a moment, and immediately understood what he meant, and said.

"Well, there are two, one is from the Yuanci Canyon, and the other is from the Ancient Demon Clan's Holy Land, compared to the Yuanci Canyon, the Ancient Demon Clan's Holy Land is safer. Ling Feng nodded and said.

"Wait, do you know where the Ancient Demon Clan's Holy Land is?" Ao Tian was a little shocked, knowing that the Ancient Demon Clan's Holy Land had disappeared from the world along with the Ancient Tree of Life tens of thousands of years ago, and no one knew its exact location so far.

Finding the Holy Land of the Ancient Demon Clan is equivalent to finding the Ancient Tree of Life, and the Life Source Liquid born from the Ancient Tree of Life is a holy object that can help a king-level martial artist break through the Holy Rank, of course his eyes are hot.

Therefore, hearing Ling Feng talk about the Ancient Demon Clan's Holy Land, it immediately caught his attention.

"Well, I was in the center of the Endless Desert from the Ancient Demon Clan's Holy Land. Ling Feng saw that he had caught his attention, and immediately smiled.

Now he is worried about the situation on Niu Lao's side, so he wants to go over and have a look as soon as possible, and as for luring Ao Tian over, maybe he can help them.

After all, although this old guy is a bit shameful, his strength is still very strong.

"Okay, let's go to the Ancient Demon Clan's Holy Land. Ao Tian didn't know that he had been calculated by Ling Feng, and now that his mind was full of life source fluid, his brain could no longer think calmly.

"The Holy Land of the Ancient Demon Clan is about 100,000 miles southwest of this place. Ling Feng told him the specific location of the Ancient Demon Clan's Holy Land, and the implication was to let him travel through the space to take him there.

After all, at a distance of 100,000 miles, he walked day and night, and it took him five days.

And if Ao Tian sent him over through the space, it would be a blink of an eye, and he didn't want to waste so much time on it.

"Hmph. Of course, Ao Tian also heard the meaning of Ling Feng's words, and snorted angrily, but he didn't say anything, grabbed Ling Feng's collar, got into the space, and when he reappeared, he came to the vicinity of the Ancient Demon Clan's holy land.

Without Ling Feng to guide the direction at all, Ao Tian had already discovered the entrance to the Ancient Demon Clan's holy land and flew over immediately.

However, he stopped ten miles before the entrance of the Ancient Demon Clan's Holy Land.

"What's wrong?" Ling Feng didn't understand what he meant by stopping suddenly, could it be that he could see that he was lying to him?

"There are people there. Ao Tian replied.

"Anyone?" Ling Feng's divine thoughts couldn't cover such a long distance, but Ao Tian said that nine times out of ten, it was true.

At this time, he finally understood why Niu Lao was so anxious before, and the feeling was that someone took advantage of Niu Lao's fusion body to be unable to exert his strength, and someone entered the holy land of the ancient demon clan.

"It's not good, someone wants to snatch the Great Void Sutra, we have to go in quickly, otherwise we won't get anything. Ling Feng was worried about Niu Lao's safety.

Immediately define this group of people as competing for the existence of the Great Void Sutra, because only in this way can Ao Tian stand on the opposite side of these people, so that the rest of the matter can be carried on.

"What, have you told others about the Great Void Sutra?" Ao Tian was a little nervous at this time, after all, this "Great Void Sutra" was something he was determined to obtain, and he would never be allowed to fall into the hands of others.

"No, absolutely not. Ling Feng hurriedly denied it.

"Then how do they know?" Ao Tian asked in disbelief.

"Didn't I say it before, I went in with the others......"

"You mean, these people may be from those big families?" Before Ling Feng finished speaking, he was interrupted by Ao Tian, and he was a little hesitant in his heart.

Because the current dragon clan cannot confront the five major families head-on, if this is really a person from the five major families, then if he makes a direct move, it is very likely to cause a conflict between the dragon clan and the five major families.

Even if you get the Great Void Sutra, the situation of the dragon clan will be very bad, after all, it will take a long time to get the "Great Void Sutra" and want to cultivate the body of the void.

"No, it shouldn't be. Ling Feng seemed to see Ao Tian's thoughts, and immediately said.

"How can you be so sure?" Ao Tian looked at Ling Feng strangely, wanting to hear him say why.

"Of course I'm sure, because they don't even know that there is a strange book called the Great Void Sutra. Of course, Ling Feng said this in his heart, and said, "Of course I know, because they haven't seen the Great Void Sutra at all, which means that they can't tell their family at all." ”

"In that case, who are the people here?" Ao Tian felt relieved when he heard Ling Feng say this.

"I don't know, but I'm sure they're not from the Five Great Families. Ling Feng was still sure of this, because the five great families had already lost their minds to the Life Source Liquid last time, and it was impossible for them to send anyone over again.

"Are you sure?" asked Ao Tian.

"Of course I'm sure, besides, the clothes on the people of the five major families have obvious marks, and I don't think there should be any on these people's bodies. Although Ling Feng didn't see it, he also guessed that eight or nine was not far from ten.

"Not really. Hearing Ling Feng say this, Ao Tian released his divine thoughts to investigate, and the result was the same as what Ling Feng said, these people did not have the symbols of the five major families on their bodies.

"Let's go. Since it wasn't the Five Great Families, then he didn't care about it at all, and as soon as his voice fell, Ao Tian took Ling Feng to kill him.

The strength of the guards outside is not low, and the lowest one also has the cultivation of the Martial Master Realm, even if it is in the Unable Family, it can be regarded as an extremely strong team.

But in front of Ao Tian, who had cultivated as a seventh-level king and had an extremely deep spatial origin, these people were no different from ants.

Even, before they could see the enemy's appearance clearly, they were torn to pieces by sharp spaces.

Soon they passed through the tunnel and came to the entrance of the Ancient Demon Clan's holy land.

It's just that after the last time, Niu Lao sealed this entrance again, and now, this entrance has been opened again, and even the stone gate that has been blessed by special power has been shattered.

It can be seen that the people who came this time are even stronger than those people in the Mu family.
