Hong Yu had already decided to cultivate the Nine Refinements of the Yuan Spirit, and he no longer hesitated.

At present, there is only one day left before the end of the assessment of the Abyss Mountain Range, and if he misses the time and fails to return, then he will lose his qualification to enter the Blue Immortal Sword Sect. But after going back, he will definitely face the interrogation and even persecution of the forces behind the top ten Tianjiao, so it has become an urgent matter to improve his strength as soon as possible.

Fortunately, after two days of continuous life-and-death battles, Hong Yu's cultivation was further consolidated, and he guided the aura of heaven and earth into the lower dantian, and there was no problem in breaking through to the peak realm from the late ninefold period.

Once you reach the ninefold peak of the Jing Yuan Realm, you can naturally cultivate the Nine Refinements of the Yuan Spirit.

"Nine Refinements of Yuanlu" is divided into nine layers, and each cultivation is a compression of the aura of heaven and earth in the lower dantian.

It means that Hong Yu must fill the entire lower dantian with heaven and earth aura, and then use the secret method of "Yuan Luo Nine Refining" to compress the heaven and earth aura. The first compression will become one-ninth of the original cyclone, and the second will be two-ninths of the second cyclone, and after repeated nine times, the merit will be considered complete, and the flawless nine-spin spirit will be condensed.

As we all know, there is a golden age for martial arts to cultivate.

The younger you are, the more potential you have!

According to Xiao Budian's statement, the reason why many Tianjiao who cultivated the "Nine Refinements of Yuanlu" in the past ended up bleak was that they had spent too much time in the process of compressing the aura of heaven and earth nine times. Second, it is also because they don't really have the know-how to comprehend the "Nine Refinements of Yuanlu".

"Young man, since you plan to cultivate the Nine Refinements of Yuanlu, this seat naturally can't let you follow in the footsteps of those ancestors. Xiao Budian crossed Erlang's legs in the Xuantian Tower, and he could see Hong Yu outside through the Divine Tower. The two dark and bright eyes narrowed into a slit, and said awkwardly, "Come on, come on, give me all the remaining elixirs in your pocket, and I will teach you a set of methods to quickly devour the spiritual energy of heaven and earth!"

"Little bit, you are blackmailing, you are robbing while the fire is burning!"

Hong Yu resisted angrily.

However, Xiao Budian didn't care at all, knocked on the big pipe in his hand that was longer than others, and said disdainfully: "This is a fair deal, you can not accept it!"

“......”

Hong Woo was defeated.

handed over the last few first-grade elixirs to Xiao Budian, and the tower god in his mind let out a treacherous smirk, and then slowly passed on a set of secret methods to Hong Yu. This set of secret methods is called "The Sea Contains All Rivers", and the little ones who blackmailed Hong Yu from more than a dozen first-grade elixirs seem to have found it in conscience and take the initiative to expand the shadow martial space.

Hong Yu practiced the "Sea Acceptance of Hundred Rivers" set of spitting exercises in the Yingwu space.

After about three hours, he had already reached the realm of mastery, and the speed of absorbing the aura of heaven and earth had increased by three times.

"It's worthy of 'Embrace of All Rivers', and the realm of mastery alone has tripled my speed. And in the realm of perfection, it can increase the speed by a full five times!" Feeling the speed of devouring the aura of heaven and earth soaring rapidly, the depression caused by the loss of a grade of elixir faded a lot.

"Embrace all rivers, suck!"

Hong Yu slowly closed his eyes and ran the Xuangong "Sea Acceptance of Hundred Rivers".

This set of Xuangong is indeed powerful, and with the threefold increase in absorption speed, Hong Yu can feel that the aura of heaven and earth around the space is converging towards his side.

If you want to fill the lower dantian at the previous speed, you must keep absorbing it for thirty or forty hours. However, under the increase of the sea and all rivers, it took Hong Yu ten hours to fill the empty lower dantian again. After filling the lower dantian, Hong Yu's whole person suddenly felt refreshed and radiant.

With so many reserves of heaven and earth aura, Hong Yu has full confidence, even if he encounters Hong Hu again, he can kill him!

And without the use of stratagem!

After all, no matter how strong Honghu is, if he is faced with three or four consecutive all-out annihilations, he is afraid that he will not be able to resist it.

"Then it's time for the first compression, which is a crucial process. ”

Hong Woo took a breath and began to compress for the first time.

"Nine Refinements of Yuanluo" is sad and heavy!

This first level is relatively simple, but it's not just anyone who can successfully cultivate it. First, it is very dangerous to compress the aura of heaven and earth, and if the aura of heaven and earth that contains terrifying destructive power accidentally explodes, it will be small to destroy the dantian, but it will explode and die!

Hong Yu carefully operated the Xuan Gong.

Once......

Twice......

Three times......

He refined the heaven and earth aura in his body again and again, until after the ninth refinement, the heaven and earth aura that was full of his lower dantian was finally compressed and turned into one-ninth of its original size. But the power and purity contained in it are even better.

"Cyclone, now!"

Hong Yu let out a low sigh.

As the "Yuan Lu Nine Refining" method was in operation, the heaven and earth aura in Hong Yuxia's dantian, which had been transformed from a gaseous state to a liquid state, slowly rotated. Hong Yu's whole body suddenly shook, more than 36,000 pores exploded at the same time, and a sharp pain made his whole body convuls.

"Hold on!"

Hong Yu clenched his teeth and persevered with a strong will.

The heart-rending pain tormented him for half an hour, and when Hong Yu was almost exhausted and collapsed, the swirling chaotic heaven and earth aura finally stopped. The size remains the same, only occupying one-ninth of the position of the lower dantian. However, on top of the aura of heaven and earth, there was an extra weird cyclone.

It is the first sign of "Yuan Lu Nine Refining".

"Buzz!"

The lower dantian shook suddenly, and the slow-forming cyclone was finally completely formed.

At this moment, Hong Yu felt that his body was filled with unprecedented power.

He tried to clench his fists and bring up a "crackling" sound, and his legs kicked violently, and his body bounced up and went straight to the top of the cave. At the moment of landing, Hong Yu walked by with his feet on the seven stars, grabbed the spear on the side, and with a low roar of "ha", the spear pierced out.

"Bang!"

A shot was fired on the cave wall.

The spear sank directly into the rock wall, and with the crisp sound of "click", cracks roamed like spider webs. The cracks grew larger and spread faster, and in the blink of an eye they were reaching the roof of the cave and still spreading. With the roar of "boom", the cave began to shake violently.

"Bad ......"

Hong Yu hurriedly put away his spear and fled the cave quickly.

"Boom!"

Almost at the same time as he left the cave, countless boulders rolled down from the cave behind him, and the entire cave collapsed directly, raising a cloud of dust.

Hong Yu stood outside and looked dumbfounded, drenched in cold sweat: "Nima, Lao Tzu almost buried himself alive?!"

In addition to being afraid, Hong Yu felt a burst of ecstasy and excitement in his heart.

The power of this blow just now was already comparable to the upgraded version of Extinction that he had used with all his might when he killed Hong Qi before, and more importantly, it was just an ordinary attack. Hong Yu was ecstatic in his heart: "Hahaha, my current ordinary attack is no weaker than a half-step Earth Spirit Realm, with a destructive power of six or seven thousand catties." If you add the extinction of the upgraded version, then the strength can definitely be doubled to about fifteen thousand, which is already more than many early stage powerhouses of the Earth Spirit Realm!"

"Yuanluo Nine Refining" is indeed powerful, and if it is tightly refined to the first layer, it will increase the combat power of De Hongyu to this point.

If it is to reach the double and triple ...... in the future,

Even the highest Nine Spins Yuan Spirit, how will his combat power change against the sky?

Perhaps, when that day comes, he will also be able to become the legendary demon who kills the Heavenly Soul Realm with the body of the Earth Spirit Realm, right?!

Gathering his mind, Hong Yu's eyes looked at the sky that was slightly white: "There are still a few hours left, I should go back too!"

Plundered the points of the Seven Heavenly Pride, and he was already destined to be the first.

The only thing to worry about is how he will face the forces behind the Ten Heavenly Prides when he returns to the meeting point outside the Abyss Mountain Range......

............

Entrance to the Abyss Mountains.

In the lined camp, the camp that had been quiet for two days became noisy again.

Seeing that noon was approaching, each of the strong men stepped out of their tents and gathered on the wide square, all eyes fixed in the direction of the Abyss Mountain Range.

According to the convention, there should be a return of Tianjiao!

But until now they have not seen anyone return......

"It's strange, there is only half an hour left before the end of the meeting, why hasn't anyone come yet?"

"Did something happen?"

"Impossible, I'm waiting here to guard it, and other strong people can't enter it at all. What's more, it is impossible for them to enter the inner area to provoke the second-order desolate beasts, so there shouldn't be any danger to their lives!"

"Wait!"

Minutes and seconds passed.

When there were still fifteen minutes before the end of the meeting, the first figure finally walked out of the abyss mountain range.

"Huh, isn't that Cao Bo, the kid of the Cao family? He was the first to come back?"

It was a thin young man, his face was pale, and his clothes were dirty and torn, and it was obvious that the two-day journey of hunting wild beasts had not been very smooth.

Cao Bo dragged his tired body back to the camp and handed over the points jade order to Hong Tiande: "Senior, this is my points jade order!"

"Hmm!"

Hong Tiande waved his hand, looking a little impatient.

Since yesterday, he has had an inexplicable panic, especially seeing that time is passing bit by bit, Hong Hu and the others have not come out, this uneasiness is even stronger.

Cao Bo was stunned, Hong Tiande's indifference made him a little unwilling, but when he thought of his pitiful fifty points, he felt bitter in his heart: "With my results, don't say the top four, I'm afraid that they are all at the bottom of the top ten Tianjiao." As a high-ranking elder of the Hong family, how can he look at me differently?"

Shaking his head, Cao Bo returned to the area where Cao's house was located.

Cao Bo's father was really the head of the Cao family, and he asked anxiously, "Xiaobo, you're not injured, are you?"

Cao Bo shook his head.

The head of the Cao family breathed a sigh of relief and asked, "Have you seen anyone else?"

"Nope!"

Cao Bo wondered, "Why?

The head of the Cao family nodded.

"Look, there's someone back!" an exclamation broke the thoughts of father and son.

Following the sound, another figure returned from the Abyss Mountains.

This person is Wang Meng!

Compared with the domineering and flamboyant before entering the mountain range, Wang Meng at this moment seems to be much more low-key, looking left and right as if he is vigilant about some terrifying existence. It wasn't until he returned to the camp that he breathed a long sigh of relief and handed over the point jade order to Hong Tiande. Hong Tiande glanced at him lightly, frowned, and said, "Wang Meng, have you seen anyone else?"

"Others?"

Wang Meng was stunned for a moment, and a look of horror appeared on his rough face, as if he remembered something extremely terrifying, and his whole body was full of spirits.

This subtle detail caught everyone's attention.

Several big families stepped forward to inquire about the situation......

"What the hell is going on?"

"Did you have an accident?"

"You bear child, speak quickly, are you going to die in a hurry?"

Faced with the questioning of more than a dozen strong people, Wang Meng's face turned a little paler, and he trembled his lips and said, "He, they...... All, all dead......"

"What? all dead?"

"How is that possible? Is it just the two of you who are alive?"

"What the hell is going on in the Abyss Mountains? Tell me, where is my Chen Hao child?"

Chen Hao's father's eyes were red, and he kept shaking Wang Meng's shoulder and asked, "Tell me, is everyone else dead except for the two of you?"

Wang Meng, who was shaken to pieces under Chen Hao's father's hands, was stunned, and a figure suddenly flashed in his mind. As soon as he thought of the young man's figure, Wang Meng hugged his head and roared in horror......

"There's still a living ......"
