Su Ji lived in Huang Feihu's palace and found that Jiuquan had alternating day and night like the human world, but the yin and yang were reversed. During the day, the snow-covered earth glows, and at night, the light on the ground fades away, and the nine springs return to darkness.

The next day, before the ground was shining, Su Ji couldn't wait outside the palace to see the five-colored sacred cow tied to the stone pillar sleeping soundly.

Next to him, Huang Tianhua was silently feeding the jade unicorn.

The scenery in front of Su Ji's eyes showed a gloomy color, only the jade unicorn that emitted green light was incompatible with the darkness around him. Huang Tianhua, dressed in armor, squatted in front of his mount, holding a basin of waist cut out of nowhere, with bright red blood on it.

Su Ji fluttered his wings and flew over, not daring to get too close to the jade qilin that was eating, but just landed on the ground ten steps away from Huang Tianhua.

Huang Tianhua kept his head down, didn't even look at Su Ji, and took out a waist bigger than Su Ji's body from the basin and fed it to the jade qilin.

Su Ji couldn't help but say hello first: "Little brother has come to ask the great god." ”

Huang Tianhua glanced at Su Ji, "Don't call me the Great God, call me Lord Binglinggong, the Three Mountains Righteous God." ”

"Got it, great god. ”

Huang Tianhua frowned, and said with an impatient expression on his face: "You're early." ”

"The younger brother knows that he is naturally stupid, and he wants to come early to ask for advice on the art of transforming into shadows, and become a new person as soon as possible. ”

Su Ji thought that he could finally turn back into a human form, so he was inevitably a little anxious, but Huang Tianhua looked unhurried, feeding the jade qilin slowly and methodically, and said with ignorance: "Transform into a shadow, you can't learn it now." You don't have the energy of Yuan Yang, you can't use mana in the underworld, you can only start from scratch. From today onwards, I will teach you how to practice qi. ”

"Lianqi?"

Huang Tianhua stretched out a finger on the hard stone pillar and wrote a big character "Qi", explaining: "'Qi', also known as 'innate vitality', is the origin of all things in heaven and earth. The so-called Yuanyang Qi is also a type of 'Qi'. Mortals in the yang world can use their physical bodies to cultivate the acquired 'qi', but now that you are in the underworld, you can only cultivate the innate refining 'qi' with your soul. If you can't rush this kind of thing, take your time. ”

"How long does it take to take your time?" asked Su Ji.

Huang Tianhua speculated conservatively and replied: "If you learn quickly, it will take about twenty jiazi. ”

"Twenty Jiazi?" Su Ji was dumbfounded and said in amazement: "Sixty years is one Jiazi, twenty Jiazi...... That's 1,200 years!"

Huang Tianhua said expressionlessly: "If you want to refine Qi in the underworld and cultivate into a shape-changing shadow, you need to refine the Qi of the meridians. It takes a hundred years for a living person to refine the Qi of the five internal organs, and it will take a thousand years for you to refine the Qi of the meridians for a dead bird. Qi is the yin energy refined by the innate element, combined with the yang energy refined by the five internal organs. The transformation of yin and yang into each other can lead to infinite changes. ”

As Huang Tianhua spoke, he turned into an elephant with thick limbs, like a gray wall blocking Su Ji's sight.

Su Ji saw four pillar-like elephant legs in front of him, and when he looked up, he saw his fan-like ears gently fanning, white jade-like ivory shining, and his thick nose stretched high into the air, swinging like a flying python.

The elephant opened his mouth to speak human words, taught Su Ji the mantra of refining Qi, and taught him the mantra of twenty-four words: "Remember, if Qi gathers, it will live, if it is strong, it will be healthy, if it gathers, it will be stopped, if it is scattered, if it is weak, if it is weak, if it is dispersed, it will die." ”

After saying this, the elephant changed back into human form.

Su Ji felt that although those mantras were complicated, they were not difficult for him. Because it mentions the main object of yin energy and the main energy of yang energy, and the two are combined with each other. These methods are actually similar to the 100-character Yin Yang Zen in the Jade Plate.

Huang Tianhua opened his right hand, and a shiny silver nail appeared in his palm, emitting a cold light.

"This magic weapon is called 'Heart Nail', which is given by the family teacher Qingfeng Mountain Ziyang Cave Qingxu Moral True Monarch. I once used this magic weapon to kill the four generals of the Demon Family. Now I want you to try to cultivate the Qi of the five internal organs and six internal organs until you can use the Qi to make this heart nail move, as long as you can make this heart nail move slightly, you will be considered done. Later, I will go back to Heaven to restore my life, and you can concentrate on cultivation here until I come back. ”

Su Ji asked, "When will you come back?"

"Cultivating the Qi of the five internal organs can easily take a hundred years. In a hundred years, I will come here again to find you. Huang Tianhua put the heart nail in front of Su Ji's eyes.

Looking at the heart-saving nail as long as a little finger, Su Ji secretly wondered if it would be possible to fiddle with this little nail under Jiuquan for the next hundred years?"

Su Ji tried to refine Qi according to the method taught by the formula. Soon the body trembled slightly, and the feathers on the whole body were soaked with sweat, as if there was a force born in the body.

At this time, the jade qilin swallowed the last big waist in Huang Tianhua's hand in one gulp, shook his head happily, licked his tongue greedily, and obviously wanted to have another piece, but unfortunately the basin was empty.

Huang Tianhua wiped his hands, got up and was about to leave, when suddenly a light flashed in front of him, and he saw a silver nail across his eyes.

There was a birdsong in his ears, and Huang Tianhua turned his head suddenly, only to see Su Ji's wings emitting a faint purple gas, and he was using the purple Qi to manipulate the heart nail. Thicker and thicker purple gas rippled and drifted, and the ice and snow melted into a pool of black water everywhere it went.

Purple Qi?

Huang Tianhua's face changed slightly, and he couldn't imagine that Su Ji could not only make the heart nail move, but also manipulate it at will in just a short period of time.

Su Ji let out a long sigh, a smile appeared on the corner of his mouth, it seemed that he had saved Huang Tianhua a hundred years of waiting in a snap of his fingers.

Huang Tianhua closed his eyes slightly, and found that the purple Qi emanating from Su Ji's body was not a pure Qi from the heart, but an unusual chaotic Qi.

In the blink of an eye, the purple qi that permeated the surroundings returned to Su Ji's body little by little. Obviously, Su Ji not only waited to refine this purple Qi, but also could put it away freely.

Huang Tianhua stared at Su Ji and said, "You can refine the Qi of the five internal organs in such a short period of time, it is undoubtedly an innate talent. Could it be that you were a pure yang body when you were alive?

"It's not. ”

"Impotence Body?"

"Not even so. ”

"Could that be ......" Huang Tianhua showed a look of surprise on his face, and said in a low voice: "It turns out that this is the reason why my father chose you, but he didn't tell me......"

Huang Tianhua couldn't help but fall into a long contemplation.

Su Ji observed his expression in a daze, and asked tentatively, "What's wrong with you, Lord Sanshan Zhengshen Binglinggong?"

Huang Tianhua suddenly came back to his senses, and suddenly his wrist flipped, and he saw two copper hammers in his hands.

Bang!

Two heavy copper hammers fell, sinking deep into the ground.

"You try to mobilize the Qi of the meridians again until you hold up these two Heaven-Breaking Hammers, and you're done. Huang Tianhua didn't say much after speaking, and turned to leave.

Su Ji tried to use the method just now to hold up the two sledgehammers, but no matter how they moved, they didn't move at all.

Looking at Huang Tianhua's departing figure, Su Ji hurriedly asked, "When will you come back?"

Huang Tianhua turned his back to Su Ji and said, "I'll come to you tomorrow." ”
