"That's right, Xuanwu!" Ling Feng remembered the abilities of the three diagrams of the Green Dragon, the White Tiger, and the Vermilion Bird, it was impossible not to think of the fourth diagram Xuanwu, and because he had obtained enough water essence before, he directly placed it in the Emperor Pearl.

At this time, a few months have passed, and it stands to reason that Xuanwu has almost been refined, and then he entered the Emperor Pearl and came to the place where Xuanwu was.

As soon as he came here, he saw a huge snake turtle with a height of two meters and a body of ten meters lying on the ground, the thick turtle shell covering most of the body, and the surface of the turtle shell was also wrapped with a layer of light blue energy, and when the breeze blew, it would bring a faint ripple, just like the surface of a lake.

Behind it is a snake tail, and the tail is a very fierce snake head.

Xuanwu is the god of defense, and in legends, even ancient beasts such as Qinglong, which are also divine beasts, cannot break through Xuanwu's defenses.

But this is not to say that it will have nothing but defense, its tail is its only way to attack, so to speak, it is the only one of all the divine beasts that integrates attack and defense.

Of course, it is best known for its defense, so its attack power is very limited, and it is not worth mentioning to other divine beasts, but it is extremely deadly to other demon beasts.

"It's already the third order. "Through the connection between Ling Feng and Xuanwu, he knew exactly the specific level of Xuanwu, and there was still a lot of water essence left, which seemed to be enough for it to advance to the fourth order.

At this moment, Ling Feng didn't let it continue refining the essence of water, but instead brought it to the side of the demon beast's corpse, causing it to devour the corpse as well.

Its feeding method is different from that of the Qinglong Vermilion Bird, it can be used both before and after, a **, a snake head devours at the same time, and can devour two demon beasts at a time, but the speed is not comparable to the Qinglong and Vermilion Bird, after all, one of them devoured a large amount of true dragon dragon qi, and the other devoured the King Kong Flame.

Whether it is dragon qi or vajra flames, they are all rare things, and naturally they have undergone abnormal changes.

However, the two heads of Xuanwu combined, they could barely compare to their speed.

After swallowing almost ten heads, Ling Feng's heart moved, and Xuanwu turned into a blue light and burrowed into his chest, and suddenly a strange power came from his chest, and then quickly spread throughout his body.

Almost in between breaths, he felt his exhausted body fully recover, and at the same time, he felt that the surface of his skin was wrapped in an extremely thin layer of water-attribute energy.

Ling Feng subconsciously took out an artifact and slashed it towards his right arm, but he found that the artifact was directly resisted by this layer of energy and could not be cut at all.

At the same time, he also felt that the exhaustion in his body had been swept away, as if he had been washed away by water.

"It seems that the energy of Xuanwu Replenishment can improve one's defense and resilience. "Ling Feng can be regarded as determining Xuanwu's ability.

Speaking of which, the role of each of these four holy diagrams is different, the green dragon devours flesh and blood, replenishing the soul and vitality, the white tiger devours flesh and blood, and the energy that is replenished can increase the strength and penetration of the true element, the energy obtained by the vermilion bird devouring the flesh and blood can increase the reaction speed and the destructive power of the true element, and as for the Xuanwu, it can increase the defense and recovery power, involving almost all aspects of the martial artist.

Ling Feng was suddenly very curious, curious about who was the person who created such an exercise, if it were him, I am afraid he would not be able to think of it.

Moreover, this is not the full version of the Four Holy Diagrams, and suddenly, he is also full of expectations for the complete version of the Four Holy Diagrams.

"I think Long Xiang is about to return to the Valley of Death. "When Ling Feng came back from Xue Qing before, he explained what she did, which was to ask her to tell Long Xiang and let him go back first with an Emperor Pearl.

In this way, he doesn't have to waste too much time, and he can enter the Valley of Death directly through the Emperor Pearl.

First, this is to facilitate him to return to the Valley of Death in the future to obtain the complete Four Saint Maps, and second, this is also a back path that he considers for himself.

After all, this Death Valley is a murderous place for ordinary people with no return, and no one would have thought that they would hide in the Valley of Death.

And the place where the Dan furnace was refined, the location Ling Feng also chose there, because the refining method of this Dan furnace was very peculiar, and the movement caused by it was probably not small, he was not at ease outside, and if he chose there, no one would come to disturb him.

"Master, your master is here. At this moment, Thirteen suddenly appeared beside Ling Feng and said.

"Got it. Ling Feng answered, releasing Xuanwu to continue devouring the corpse of the demon beast, while he himself left the Emperor Pearl, and as soon as he came out, he saw Tianxin pushing the door and walking in.

"Master?" Seeing the visitor, Ling Feng was stunned for a moment, because this was a woman in her twenties and thirties, she was still charming without powder, if it weren't for her appearance being a little similar to Tianxin, coupled with her aura, Ling Feng really couldn't believe that she was his master.

Although this was caused by him, it was the first time he had seen Tianxin's appearance.

"What do you think?" Tianxin glanced at Ling Feng, but she could see that she was in a good mood, and if she didn't say anything else, she said that she had regained her youthful appearance, which was enough to make her happy.

It's a woman's nature, and that woman doesn't love beauty.

As for the rest, needless to say, the divine soul broke through the realm of the martial master, and broke the common sense to give birth to the primordial spirit, and the physical condition is also better than before, I don't know how many times, as long as she is given enough time, it is not a problem to cultivate to be promoted to the martial master.

Either way, it was something she never dreamed of.

"Hehe, Master, someone told you that you are beautiful?" Ling Feng saw Tianxin like this, and his heart was full of joy.

It's not that he's bold, it's that Tianxin's appearance at the moment really makes him unable to raise the respect he had before, after all, she doesn't look much bigger than herself now.

"You kid, you dare to even make a joke from Master, right?" Tianxin said this angrily, and then walked to Ling Feng's bed and sat down, and said, "How is it, is it better?"

"Well, it's almost too good to be true. Ling Feng said and did it, at this moment he was really almost recovered, but suddenly remembered the Yuan Spirit born in Tianxin, and said curiously: "By the way, Master, didn't you give birth to the Yuan Spirit, release it quickly and let me see!"

"Hmm!" Tianxin did not refuse, and as soon as his heart moved, Yuan Ling flew out directly from the center of his eyebrows.

But when Ling Feng saw this Yuan Spirit, his eyes immediately widened, because this round neck was not something else, but his own Fang Tian Painting Halberd.

"How could this be?" Ling Feng was so shocked that he didn't know what to say.

"You ask me, I still have to ask you, did you do something to let me give birth to the Yuan Spirit?" Tianxin is also very strange, after all, the Yuan Spirit only has a chance to be born when you first enter the True Martial Arts, if you fail to be born in the True Martial Arts, then it is impossible to have it in this life, even if you advance to a higher realm.

However, after this matter was involved with Ling Feng, there was a change, so she thought that Ling Feng had done something for her that allowed her to give birth to the Yuan Spirit.

"Master, you think too highly of me, if I have this ability, then I don't have to do anything, I don't have to worry about anything if I give birth to the Yuan Spirit for others. When Ling Feng heard Thirteen talk about this matter, he was also very strange, and he didn't expect the result so far.

But one thing is for sure, it must have something to do with you.

"You kid, you talk nonsense. Of course, Tianxin knew that this matter had something to do with Ling Feng, and he could see that even he himself didn't know what was going on.

However, no matter what happens, it is always a good thing to be able to give birth to the Yuan Spirit.

"By the way, Master, you haven't started cultivating yet, have you?" Ling Feng suddenly remembered something and said busily.

"Not yet, what's wrong?"

"It's good if you don't have it. With that, Ling Feng got up from the bed, then came to the table and laid a dozen blank papers, and said to Tianxin, "Master, please help me polish the ink." ”

"What kind of fame are you going to make?" Tianxin was puzzled, but he still walked over and picked up the inkstone and grinded it.

"Hehe, you'll find out later. With that, Ling Feng picked up the brush, dipped it in ink, and began to write.

While Tianxin was grinding ink, she stood beside Ling Feng and looked at what Ling Feng had written, the more she looked at it, the more shocked her expression became, and in the end she even forgot about grinding ink.

"Apprentice, what you wrote is ......"

"Haotian Battle Qi, the ground-level high-grade exercises, Master, don't underestimate it, it's a miracle skill, even if it's the ground-level top-grade exercises, it may not be comparable to it. Ling Feng said as he wrote.

"This is the Haotian Battle Qi Exercise?" Tianxin had obviously heard of this exercise, and was a little shocked.

"What, Master, have you heard of it too?" Ling Feng couldn't help but ask when he saw that Tianxin was like this.

"Not only have I heard of it, this method is the treasure of the ancient One Qi Sect, and it is a rare exercise, but later the One Qi Sect fell, and this exercise disappeared, and later I heard that it was acquired by the Martial Arts Holy Land Tianfeng City, as for whether it is true or not, no one knows, but even if it is true, I am afraid that it disappeared with Tianfeng City more than a hundred years ago. Speaking of this, Tianxin paused and said, "How do you know this exercise?"

"Master, there are some things I don't want to lie to you, but I can't say anything about them, so ...... You still don't have to ask me. Ling Feng shook his head and said.

"Well, in that case, then I won't ask. Tianxin could see that Ling Feng had something unspeakable, and Ling Feng was able to tell him this, which already showed that he trusted himself very much.

Otherwise, he made up a random reason, and he didn't know if it was true or not.

"Master, don't worry, I will always be your apprentice, and you will always be my master. Ling Feng said sincerely.

"You kid, I told me what I wanted to say, what should you let me say?" Tianxin said a little speechlessly.
