This is the essence of the Heavenly Acupoint.

There is no beginning, so there is no end, there is no life, and there is no death.

It is a circle.

However, among the six major branches of the Heavenly Cave Sect, except for Hua Luan, the other five veins deviated from an incomparably long distance.

Because no one can understand why life and death can be transformed into each other.

This is a creation brought by the Netherworld River to the first sect master, but with the outbreak of the vision of the cave, no one has gone deep into the cave, the first sect master only left a strange spar, hurriedly selected the heir, and rushed into the cave, and since then there has been no news.

That spar was carefully preserved by the warriors of the Hualuan branch, because it contained a period of time and space that existed in the past, but due to the complex spatial structure, only a few people could see the creation process of the Heavenly Cave Technique by chance.

Now, this spar is placed in front of Yu Ling and Xue Qingling.

They had returned to reality from that period of time and space, the Styx River was gone, the Cave was gone, it was just an empty stone room, only a huge stone tablet stood in the center, and on the stone tablet lay the incomparably precious spar, a layer of milky white halo formed a barrier, sealing the spar inside.

"So what happened to the Heavenly Cave Vision back then?" Yu Ling hurriedly asked while the Gnature King was still asleep.

"To put it bluntly, this king took his clan and the resentful spirit clan to fight hard, and as a result, those resentful spirits began to play yin, attracting the power of those broken souls in the water of the Netherworld, wanting to kill this king. This king didn't expect them to be quietly laid out behind the back for hundreds of years, when the entire Netherworld River was about to be overturned, and this king had no choice but to rush to the Yang Realm, during which the dead qi mobilized seemed to be a bit excessive, and finally accidentally caused the tide of the Heavenly Cave. ”

"But this can't be blamed entirely on the king, the Wraithing Clan is also half of the responsibility. Whoever let them toss so much, if the Netherworld River runs well, the Cave tide will definitely not break out. ”

"As for the first sect master of the Heavenly Cave Sect...... This king actually didn't see him at all, because he was a little weak after coming to the Yang Realm, so I returned to the original state, scattered in the bodies of several mutated beasts and fell into a deep sleep, who would have thought that as soon as I woke up, the Heavenly Cave Sect would be destroyed, and Zhao Lan's bastard boy also sealed this king in the Valley of Wild Beasts, it was really a tiger falling into Pingyang and being bullied by dogs!"

No matter how huge the amount of information is, the gnature king directly said it all in one go.

After finishing speaking, it seemed to calm down a little, paused for a few seconds and said: "Wait, then again, this thing is a bit strange, the first sect master of the Heavenly Cave Sect is really a genius, this king doesn't know that the Netherworld River is round, and he actually observed it, so he will never have any problems surviving in the Netherworld, why did he disappear for thousands of years and never appear again?"

"You don't know, and I don't know. Yuling shook her head and said.

The Gnature King had no choice but to guess on his own: "That guy is a madman, maybe he came up with a new trick to die, but he can't come back?" It feels a bit far-fetched, with his circle of life and death, it seems that he can't die no matter how he does, so he may be trapped? Or, he doesn't want to come back? If only the cave was still there, this king really wants to see what happened after the tide broke out back then, and my people, I don't know how many ...... can be left."

"Netherworld and Yang Realm, is there only one passage in the Heavenly Cave?" asked Yu Ling.

"Actually, you can understand the Netherworld as the opposite of the Yang Realm, and the Netherworld River flows at the junction of the two, if that Heavenly Cave Sect Sect Master goes some distance further, he can come to the real Netherworld, which is the range of activities of our dead creatures. ”

"The two worlds are not absolutely opposed, the space will occasionally distort and fall, at this time the two worlds of yin and yang will be temporarily connected, but this kind of passage is random, and it is fleeting, anyway, this king does not expect to meet. I've only seen one stable passage, but unfortunately I can't find it now. There was a hint of wrenching in the gnat king's tone.

Yu Ling was pondering his words and preparing to comfort him, when the Gnature King said excitedly: "Forget it, it's useless to talk so much, you should see Zhao Lan soon, right? ”

…… It seems that the world of living things and dead things still has something in common, for example, the power of power determines the right to speak.

"Don't you look at the stone stele, which is engraved with the "Heavenly Cave Formula", and on the back is a modified version of the Hualuan branch. Xue Qingling had already circled the stone monument.

Yu Ling had the time to carefully browse the stone tablet, "Heavenly Cave Jue" has a total of nine layers, from the strong tendon period to the chaos realm, even the immortal realm above the chaos, there are only a few words to describe it, which can be regarded as providing an idea for the latecomers.

According to the speculation of the first sect master of the Heavenly Cave Sect, if the circle of life and death can be completed and reach the realm of the Netherworld, then it is equivalent to immortality.

He said he would practice the path, regardless of whether it ended up being a success or a failure.

Yu Ling looked at the Hualuan branch vein version on the back again, and in general, it had changed by thirty percent, which was equivalent to a simplified version of the genuine Heavenly Acupoint Technique, otherwise, except for the first sect master, no one would be able to truly comprehend the true meaning of the circle of life and death.

But Yu Ling's situation was more special, he had seen the Netherworld a long time ago.

He will not forget the intoxicating purple light like fireflies in the sky, and the insurmountable barrier between the yin and yang worlds.

Fortunately, if Zichen was finally saved by him with soul condensation, otherwise Yuling might not forgive himself in this life.

And that strange state of the netherworld, which is also an experience that is difficult to describe in words.

The Circle of Life and Death...... Yu Ling faintly understood.

Although he would not give up the Gu Yang Jue and change to the exercises of the Heavenly Cave Sect, this was a completely new idea after all, and there were many things for him to learn from.

He can't do the transformation of life and death, because he is far from touching that realm, but everyone's understanding of the circle of life and death is different, and the circle itself is a concept with a wide extension.

For Yuling, the circle has no beginning or end, its essence is a cycle.

That's right, the cycle, the great cycle of the three major systems, the cycle of the ancient yang recipe and the original recipe of the Dao......

Yu Ling felt that this path was feasible, and he had already conceived a basic prototype, but it still needed further practice.

If he succeeds, he will accomplish an unprecedented feat of truly integrating the three independent systems into one, and the two great skills into one.

Refining and refining qi, refining qi and transforming gods, this is a single-line process, and the direction he will work towards in the future is to connect the essence and spirit to form an infinite circle of circles, so that the Xuan power can be transformed into spiritual power, and the spiritual power can be transformed into soul power, and even the soul power can be transformed into Xuan power.

This sounds ridiculous, but Yu Ling has not forgotten that Shuo, who is a member of the Yan clan, naturally has the talent to transform spiritual power and soul power into each other.

"Let's go, I'm done. Yuling straightened up, feeling a lot of emotion in his heart.

Although he didn't even know what the name of the first sect master of the Heavenly Cave Sect was, the Heavenly Cave Recipe left by the other party, as well as the image that existed in the past, did give Yu Ling great feelings, and it could even be said that it pointed out the way forward for him.

He didn't need to cultivate the Heavenly Acupoint Technique, because the true meaning and essence of the Heavenly Acupoint Technique were already in his heart.

"The door is over there. "Xue Qingling has already finished exploring this stone chamber.

Yu Ling looked around, except for the stone tablet and the spar, there was nothing left here, so he nodded and said, "I don't know what the inheritance of the other veins looks like." ”

"I think it's still more precious to have such a knowledge, and it's worth the trip. Xue Qingling glanced at the spar sealed in the barrier.

With some respect for the first sect master of the Heavenly Cave, the two quietly pushed open the stone door and came to a hall that seemed to be used for gatherings.

"Why are you here?"

As soon as Yu Ling came out, she heard a familiar voice, and turned her head to see that it was Bei Ran, and there was a shy and timid Wen Shu standing next to her.

Yu Ling responded, and his gaze quickly swept over the rest of the people.

Except for Pei Tianling, who had a gloomy face, Yuling didn't know anyone.
