But Liu Changqing does not have a spiritual sea, the most basic thing cannot be realized, and he can only rely on the book spirit to release a large amount of spiritual power plus the rapid inhalation of spiritual energy, forming a hard core before the spiritual power is exhausted, and then slowly forming a pill, which is much more difficult than that of ordinary monks.

Swallowing one Barrier Breaking Pill and two Shengyuan Pills, Liu Changqing concentrated his mind and endured the severe pain to let Shu Ling quickly release Xuantian True Qi. Because Liu Changqing has both the righteous path and the demon path, he can also use the demon skill to form the pill! But he first wants to use the Xuantian Gong to form the pill, because if he wants to form the demon pill with the Ten Thousand Ghost Dynasty Sect, it is best to choose a place full of demonic qi to form the pill, so that the chance of becoming a pill is much greater. Once he uses his magic skills to form a pill, he will be a double golden pill monk!

Rumble!

Breaking the barrier pill belly, the entire dantian began to boil, even the golden demon yuan set off a huge wave, the powerful spiritual power actually had to go upstream, along the meridians reversed, fortunately, Liu Changqing has the experience of urging the demon yuan, endured the swelling pain of the meridians, while signaling the book spirit to release the Xuantian true qi, while quickly running the Xuantian Gong method, guiding the powerful spiritual power to hover over the dantian, little by little to form a spiritual power vortex, forcibly compressing the spiritual power, in order to achieve the purpose of forming a hard core, but the spiritual power is sometimes condensed, sometimes scattered, and the hard core cannot be formed for a long time, and the compression and dispersion form a confrontation situation for a while。

Liu Changqing was not in a hurry, he understood that his cultivation was already very difficult, not to mention that he didn't have a spiritual root, how could he be a very simple knot, and slowly the cave fell silent, only the sound of a trace of spiritual power seeping into his body through Liu Changqing's facial features and the futon under the seat. Speaking of this strange futon, Liu Changqing was glad in his heart that this strange treasure could make the manic aura in the air become as docile as a lamb, greatly reducing the pain in the body, and allowing the aura to continue to enter the body steadily.

Because to form a golden pill, the spiritual power required is extremely huge, and the spirit gathering array arranged by Liu Changqing this time is composed of one hundred and ninety-eight high-grade spirit stones, and the spiritual energy is rich into white snakes, constantly drilling around, and being sucked into the body by Liu Changqing.

Time passed day by day, until Liu Changqing's tenth year of retreat, after two years of tug-of-war, although there has been no hard core, but Liu Changqing's mana is becoming more and more refined, and the compression ratio is getting higher and higher, on this day, the spiritual power vortex has become dark cyan, through internal vision, Liu Changqing found that a hard core the size of a millet grain appeared in the center of the vortex, and he was overjoyed, and hurriedly increased the input of spiritual power, the spiritual power vortex rotated faster and faster, and the hard core of rice grains slowly became larger, and the spiritual energy in the cave swarmed in, and even the entrance to the cave on Qilian Mountain formed a spiritual energy belt, and the illusion exit leading to the canyon also inhaled a large amount of spiritual energy, Liu Changqing's body slowly swelled, the blood vessels on his face burst out, and his face was hideous, if it wasn't for the alchemy technique, it was already in the early stage of the Iron Bone Realm, and he would have exploded and died.

Liu Changqing endured the severe pain, and began to slowly control the hard core in the vortex of spiritual power, absorbing little by little the aura that rushed into the dantian, as the hard core rotated faster and faster, the replenishment of the aura was not enough, Liu Changqing hurriedly ordered the book spirit to release the spiritual power, for this time, Liu Changqing deliberately went out, except for the seventh-level prison cell, except for the trapped turbidity sun god Jun Yuanshen, the other six rooms were full of Xuantian true qi, just worried that the aura of the knot pill was not enough.

Now above Liu Changqing's dantian, there is a demon emperor relic hanging, and the other is a two-story cell, one on the top and seven on the bottom, because the top is the heavenly prison department, and the level is higher than the dungeon department below, which can capture fifth-level demon beasts like three-legged crows, and the lower cell can trap the monks and fourth-level demon beasts under the yuan infant, and the greater use is to trap the spiritual power body of the yuan god and soul, but the number is too small, and the storage of spiritual power is not enough. The upper one of the cell cells was larger than the four below.

Fortunately, the cell of the Heavenly Prison Department has an advantage, it can change in size, after the transformation of the book spirit, it is divided into four areas, so that the three-legged crow can stay in one corner, and the other three areas can store some items, Liu Changqing's things are placed in one corner, and the other two areas have become the aura temporary storage room, which is also full of Xuantian true qi, in order to tie the Dan only, otherwise, the book spirit will not pry Liu Changqing to tie the Dan.

Soon, the spiritual power in the six dungeon cells was exhausted, and Jin Dan became the size of a pigeon's egg, pale cyan, and the aura flowed, making it look different. Although Liu Changqing was strange, he also knew that the other monks' golden pills were all pale golden, but why was his own pale cyan? But now was not the time to consider the color, so he hurriedly asked the book spirit to release the spiritual power in the Heavenly Prison Department.

The spiritual power in the Heavenly Prison Department is much purer, and soon the golden pill will turn dark blue, and it will also change from the size of a pigeon's egg to the size of an egg, and the speed of rotation will also be full, and it will gradually stabilize.

Liu Changqing let out a long breath, and finally succeeded in forming a pill! A powerful breath erupted from his body, and a chilling wind was formed in the cave, and suddenly the wind in the cave was fierce, and the sleeping little fox and the thin scales and the advanced two-tailed thunder fire scorpion were all frightened and hidden, and they didn't dare to come out.

Liu Changqing had just stood up, and a powerful coercion fell from the sky, giving people a feeling of palpitations.

Liu Changqing was taken aback, and hurriedly shook his body slightly, disappeared into the cave, and came to the open space of the canyon. At this moment, the sky was full of dark clouds, thunder and lightning rolled, black pressure came from the oppression, lightning and thunder between the dark clouds, as if the sky was about to be torn apart.

"Master, I didn't expect that one of your advances could actually lead to the four tribulations of the Four Nine Heavenly Tribulations, although the Heavenly Tribulation is powerful, once you can survive the Heavenly Tribulation, the benefits are extraordinary, you have to be careful!"

Ordinary monks will only fall a wave of heavenly tribulations after they advance, and the tribulation clouds in the air are obviously not a wave, but the four tribulations mentioned by the book spirit, that is, the four waves of heavenly tribulations, and the most powerful is still the nine tribulations! The four tribulations have already made Liu Changqing tremble, this is the first time he has faced the heavenly tribulation, and he hurriedly sacrificed the triangular bone shield that he had practiced, and then used his spiritual power to form a spiritual power shield, and then looked up at the sky.

The clouds in the air are like Mount Tai pressing on the top, and the depressing ones are breathless, and the thunder with the thickness of a thumb shuttles through the clouds, and it is actually purple! Liu Changqing's pupils contracted, when he saw the unicorn crocodile rhinoceros crossing the tribulation, it was a cyan thunderbolt when he saw the cloud swamp, how could it be his turn to turn purple? After thinking about it, Liu Changqing pointed with one hand, and a leaf covering the sky flew into the air, turning into the size of an acre, blocking the top of his head, just blocked, the first thunderbolt came down.
