Looking at the snake corpse that was 100 meters long and winding on the ground, Xia Gui also exhaled in fear. He was such a formidable opponent that he had to kill him through self-depletion.

This is just a pit viper leader who has been cultivated for fifty years, and if it is replaced by a heaven-swallowing python that has been cultivated for a hundred years, the consequences will be unimaginable.

The excitement slowly calmed down, Xia Gui slowly walked to the snake and found the seven-inch part that had been fatally hit by himself just now.

After the pit viper died, the snake's skin tentacles were still sticky, but the snake's body became unusually cold. At the part where it had been pierced by itself, a naidan the size of a thumb cap rolled out.

This Nedan has a goose-yellow color, like an amber that has not been frozen for long, with a mysterious yellowish sheen in the moonlight. Looking closely, there are countless filament-like spiritual flocs in the inner dan that are slowly circulating, spinning, and a rich aura emanates from the surface of this inner dan.

"The quality is good!" With Boudin's cheers, his phantom image was also projected on Xia Gui's side, looking at the thick Neidan in Xia Gui's hand with a smile.

Boudin praised again and again: "The quality of this fifty Neidan is excellent." It's no wonder that this pit viper is a little more powerful than usual. ”

Xia Gui looked at the Neidan that had been seriously injured and consumed himself, and a complicated look flashed in his eyes.

He could feel the rich spiritual power contained in this Inner Dan, and it was indeed a Inner Dan far beyond the same level. In the final analysis, it is also something that I have worked hard to get, and there is a strong sense of joy in my hand.

If you add up the inner pills of the more than 100 little snakes before, then he has a batch of valuable elixirs in his hands to improve his cultivation. Although he didn't find the Sky Swallowing Python, it was also a hard-won reward for his hard work in sweeping this hill.

Xia Gui spread all the Nedan in front of him, and his mood was inevitably excited.

"Teacher, can these things really make me jump to the fourth order in one go?" Xia Gui asked in disbelief.

Boudan smiled, "I don't dare to say anything else, just this fifty-year cultivation Inner Dan will definitely allow you to jump to the fourth order." Of course, you have to absorb and refine according to the method I said. ”

"Is the teacher's method any different from others?" Xia Gui was puzzled.

Budan said: "It's nothing, it's just that the old man has made some improvements in the ordinary refining method of absorbing the Inner Dan, so that the absorption rate of the Inner Dan can be increased by one-fifth." ”

Xia Gui gasped.

When a cultivator refines and absorbs the Inner Dan, it is often inevitable that there may be a loss of absorption efficiency. It is a pity that these pure and rich spiritual energy are wasted and consumed like this. Therefore, cultivators will try to improve the absorption efficiency of the inner pill, and even develop a discipline dedicated to the study of the absorption efficiency of the inner pill.

It is very difficult to absorb the efficiency of the inner pill by one-tenth, and it requires the blessing of many magic weapons and pill spirit arrays. If it is increased by one-fifth, it is definitely considered a god.

Seeing Xia Gui's salivating appearance, Bu Dan couldn't help but roll his eyes, and said angrily: "The old man's method is also limited to the absorption and refining of Inner Dan under a hundred years. If the quality and order of Nedan are high, then there is no way, and the old man is still pondering. ”

Although this method is only limited to Inner Dan under a hundred years, it is enough for Xia Gui at this moment.

At the beginning, as the sixth prince, the quality of the Nedan attacked by the generals under his command could hardly surpass that of this pit viper who had been cultivated for fifty years. This inner pill, coupled with the efficient absorption and refining method, the benefits are self-evident.

"The mantra of refining, you can take a look. Boudan smiled, stretched out his phantom-like palm and wiped it in front of Xia Gui's forehead, and suddenly one after another mantras poured into Xia Gui's mind.

"Little Soul Blessing Refining Method?" Xia Gui read the name of this refining formula, and I have to say that this name is really a bit awkward.

Feeling the large number of refining mantras in his mind, Xia Gui also carefully understood it, and obtained the essence of it. I have to say that Boudan is indeed an excellent high priest, and although this little soul blessing refining method is only effective for Inner Dan of a hundred years and below, its improved efficiency is really terrifying, and it can definitely be called amazing.

Boudan fully mobilized the power of the soul, using the blessing of the soul power to wrap and refine the essence of the inner pill, so that the loss of the essence of the inner pill can be reduced to a minimum.

Now that Xia Gui finally understood, it was no wonder that the name of this refining method was called "Little Soul Blessing Refining Method", precisely because it used the power of the soul.

"Teacher, why didn't I find out that you were a ...... Genius!" Xia Gui couldn't help but praise.

Boudan sneered and laughed, "The old man is the high priest of the Southern Wilderness Country, and isn't it the old man who is the best at pondering the alchemy medicine formation and the formula for improving efficiency?"

Boudan snorted, "Okay, let's not talk about it, let's try the old man's refining mantra quickly." ”

Xia Gui nodded slightly, and didn't ask any more, he swallowed the inner pill of the more than 100 little snakes, as well as the good quality pit viper inner pill, and then began to refine according to the instructions in the formula.

It was a breezy and cold night, the stars and the moon were hanging high, Xia Gui'an sat quietly on the top of this dead and desolate hill, and began to seal his hands, his eyes and nose, his nose and his heart, and his consciousness gradually sank into the depths of his soul.

The true qi circled along the veins, and finally came to the place of the dantian. As Xia Gui meditated, settled, and meditated, he entered a deep state of soul dormancy. True Qi flowed silently in his body, and if he looked closely, Xia Gui's cheeks were extremely peaceful, like a sleeping baby, and True Qi flowed almost spontaneously.

The True Qi slowly rotated again, coming to his many Qi Points, and at each of them, he began to slowly circle and stay. And the inner dan in the dantian is also exuding wisps of spiritual energy essence, penetrating into the acupoints and integrating with the true qi.

A long wind blew, the messy hair in front of Xia Gui's forehead flew, and his robe flew with it, he was like a sleeping child, completely immersed in the refining of his mind, unaware of the outside world.

The moonlight stretched his figure, and his slightly thin figure was projected on the mountain wall, as tall as a majestic mountain, standing still.

Boudin looked at Xia Gui's figure, with a distressed and relieved smile on his face.

The youngest disciple he accepted, although he was a powerful person, experienced calamities and sufferings that others could not experience. In this process, he did not complain, silently endured all the gifts given to him by fate, and at this moment, his state of mind, his character, and his cultivation finally began to be reborn, becoming more and more tenacious and powerful.

Nedan was absorbed by Xia Gui little by little, and the aura on Xia Gui's body became more and more powerful.

A domineering and incomparable energy swirled and melted rapidly in his dantian, and then blended into his veins in a subtle way.

This domineering power was constantly removed by the true qi, warming the acupoints and blood veins all over the body, and the aura essence in it was constantly integrated into the flesh and bones. Whenever this essence was integrated into the flesh and blood, Xia Gui's meridians also faintly glowed with a faint white light, and under the illumination of this moonlight, it actually glowed with a chalcedony-like texture.

About an hour passed.

Budan looked at Xia Gui, who was still asleep below, with a smile, and said proudly: "It looks like it's almost over." The absorption rate of this inner pill has reached eighty-seven percent, and the loss is very low, and the old man's little soul blessing refining method is really amazing. ”

Under Boudin's gaze, the last trace of essence in the inner dan was also absorbed. When the last drop of essence was submerged in Xia Gui's veins and was refined cleanly, Xia Gui's body trembled violently like a lion that suddenly woke up.

"Breakthrough?" Boudin's eyes widened suddenly, and a light of surprise bloomed.
