Make a plan, Yeyang got up, and went to find a suitable environment for cultivating the [Netherworld Heart Sutra].

An hour later, he came to a deep valley about 100 zhang deep, this deep valley was located between two mountains, the sun could not shine into the bottom of the valley all year round, and he could feel the cold breath wafting up from below when he stood on the side.

Yeyang took a deep breath, felt cool all over, and his soul was much more comfortable, and then jumped down. At a height of tens of meters, jumping down is not much of a difficulty for building the foundation realm, but when he is about to come up, he should have a headache.

The bottom of the valley is filled with a black mist, this mist is called yin, and it is also a type of yuanqi, which is somewhere between death and darkness. Staying in this kind of place for a long time is harmful to others, but for those who cultivate these two kinds of vitality, it is a rare and excellent cultivation environment.

Ye Xiao also felt very fresh, after playing for a while, maybe he felt tired, so he lay on the ground and fell asleep, wisps of yin qi entered its body, and there was no need to refine, for him, sleep was the best cultivation.

Under the black mist, I could only see the distance of about five zhang around me, and I could vaguely see some black vines. Yeyang sat down cross-legged, put the Dharma seal on his thigh, closed his eyes, and carefully felt the three souls and seven spirits in his body.

After a long time, Yeyang's body emitted a little fluorescence, and seven stars like fireflies flew out of his body, and his body was a lot more illusory. Immediately afterwards, the three figures of one blue, one white and one black walked out one after another, and at this time, Yeyang Dao's body really became transparent, without the slightest breath of life.

The three figures sat around the illusory body of the night sun, and the seven star points above them also continued to rotate, and finally slowly stopped, floating above the black figure, and rushed into its head, while the other two figures also disappeared into the black figure, leaving only the black figure with a growing aura.

"Huh!" The black light flashed, and the figure rushed into Yeyang's body, and the illusory body became condensed again, and an eerie aura emanated from him, making people shudder.

According to the tradition of the demon world, the three souls in the body of living beings are divided into evil, righteousness, and evil, and what Yeyang has to cultivate first now is the evil soul of the three souls - the soul of evil.

"Hu ......" only heard the wind howling, and the black mist at the bottom of the valley frantically surged towards the night sun, forming a whirlpool that shrouded him in it.

Strands of black vitality quickly entered Yeyang's body, circulating along the meridians according to a specific line, and most of the vitality was eliminated and discharged from the body on the way, until in the end, only a few thin lines as black as ink were left into the empty dantian, slowly filling it......

There was food and water prepared in the Langya halberd, so in addition to going out every morning to practice the Purple Qi Donglai and Hongmeng Alchemy, half a month of Yeyang was spent at the bottom of the valley, and a total of nine hundred and eighty-one layers of the Netherworld Heart Sutra were reluctantly cultivated by him to the first layer, and the pitch-black vitality in the dantian also reached about five percent.

In the morning, as soon as he finished cultivating the Purple Qi Donglai and Hongmeng Alchemy Technique, Feng Lao appeared behind Yeyang and took him to the plain where he was reborn, and as soon as he arrived here, he was shocked by the scene in front of him.

The plain is divided into three distinct parts, one of which is neatly stacked with hundreds of pieces of iron ore, ranging in size from a few zhang high to a few feet in size.

Feng Lao pointed at these iron ores and said, "This is hematite, a fist-sized hematite can withstand the strength of a thousand catties, you will need to use pure physical strength every month in the future, and smash a piece of hematite into crumbs with your bare hands." ”

Without looking at Yeyang's jaw that was about to fall off, Feng Laoyou walked to a pile of gray bricks like a hill: "This is a limestone brick, the texture is fragile, each piece can only bear the weight of ten catties, you ......"

"How much is this going to smash, let it go!" Without waiting for Feng Lao to finish speaking, Yeyang patted his chest this time and said, "This kind of little thing, come and smash as much as you want!"

"This isn't for smashing, then!" Feng Lao shook his head and waved his hand to throw a halberd.

Yeyang went to pick it up with one hand, but almost fell, and hurriedly held the pestle on the ground with both hands, looking at the two-zhang long and baby-thick halberd in his hand, his face was full of surprise: "It's so heavy, this is at least a few thousand catties, right?"

"This is a 3,000-pound black iron halberd, and every month you have to use this halberd to carve an inch-deep character on ten limestone bricks. ”

"What!" Yeyang felt his head grow for a while, and it was a problem to even hold it, let alone write it. The first two items are so difficult, and the remaining one is not so simple: "What's the end?"

"You better feel the last item yourself!" Feng Lao waved his robe, lifting the night sun under the final ice cave.

"Ouch!" The ice under the ice cave was extremely smooth, and Yeyang suddenly fell on the ice, and it took a long time to tremble and stand firm, and then asked in disbelief: "It's that simple?"

Feng Lao smiled: "This is the beginning. ”

"Huh!" a piece of more than a dozen catties of ice fell, smashed on Yeyang's body, a piece of red and swollen appeared, its hardness was no less than hematite, if this ice block was usually smashed on him, there was naturally no problem, but at this time he even had a problem standing, and a blow hit, making him almost fall.

After a narrow blow, another block of ice fell, right in the middle of the night sun, but this time he was not so lucky, and was smashed out of the air.

"When you stand, the droplets fall into the barrel, and you need to fill the bucket a month. Feng Lao pointed to the corner of the ice cave.

Only then did Yeyang notice the half-bronze wooden barrel in the corner, and his eyes widened: "With such a big wooden barrel, it will only be full in the Year of the Monkey!"

Elder Feng stroked his long beard: "No more, no less, it will be full in ten hours." ”

“......”

At the beginning of a new cultivation, Yeyang fell into a penance day and night, smashing the hematite is good to say, at the cost of his blood and exhaustion every day, it took ten days to finally smash a three-foot square piece of hematite into crumbs.

And the carving on the limestone bricks is much more difficult, the first three days, the night sun did not carve a piece, the heart can't help but become impatient, in the anxious mood is another five days passed, still there is no gain. In the end, he simply went with the flow and stopped thinking about the task, but calmed down, and carved ten limestone bricks that were on the verge of breaking and the handwriting was crooked in ten days.

The final skating was much easier than the lettering, and it took only eight days to fill a bucket of water.

The three cultivation days before and after add up to thirty-six days, which is six days more than a month, and is superimposed on the next month's cultivation time. At this time, Yeyang was not in a hurry to complete the task, but went to cultivate the vitality again.

The amount of vitality in his dantian has been reduced by eighty percent, and there is less than one percent left, which is not because the vitality has dissipated, but because it has been squeezed and contracted in penance. It's just that this compression has stopped three days ago, which is a manifestation of being compressed to the extreme, and it took Yeyang thirteen days to fill the vitality in the dantian to five percent before he began to complete this month's task.

This month's penance was much faster, it only took twenty-five days, but with the addition of the thirteen days of cultivating the Yuan Qi, another five days were owed, making a total of fourteen days.

In the third month, because of the [Netherworld Heart Sutra] breaking through to the second layer, it only took eight days for Yeyang to cultivate the vitality, and then it took twenty days to complete the task, and two days were returned, and twelve days were still owed.

In the fourth month, he owes eight days, and in the fifth month, he owes only four days. At the end of the sixth month, he had completed all the days he owed, and he had two remaining days to cultivate the [Netherworld Heart Sutra], which belonged to the gradually increasing power.

By the time it was a year, Yeyang had already cultivated the [Nether Heart Sutra] to the fourth layer, and the gas vitality was also filled with one-tenth of the dantian.

Cultivation has no years, and nine years have passed, on this day, Yeyang sat in the black deep valley, and the inky black vitality surged towards him, and the wisps of vitality operated in the meridians for a great week and then entered the dantian that was already too full to be full.

Ordinary people can't help but break through when they reach this point, but Yeyang is unmoved, still suppressing, squeezing a few traces of vitality into a thread, a trace after a trace.

Finally, a critical point arrived, the vitality in the dantian suddenly rioted, Yeyang's body trembled violently, a mouthful of reverse blood spurted out, his face was firm, his green muscles burst out, the magic seal in his hand changed, and the [Netherworld Heart Sutra] was running at great speed: compression!

With a bang, Yeyang felt that all the gas and vitality in his body disappeared, leaving only a drop of emerald dark green liquid.

Yeyang showed a smile, wiped the blood from the corners of his mouth, and spent another three days consolidating his cultivation, and then got up, using his hands and feet together, and flexibly climbed up the deep valley to the square of cultivation.

There are more than 100 pieces missing in the hematite pile, but the rest are relatively huge, he walked to a piece of hematite more than a zhang high, shouted, and a series of fists fell up, a set of boxing techniques were displayed without using the vitality of the body alone, the boxing method was fierce and domineering, and the destructive power was very strong, it was the best fist method of the spirit level passed on to him by Feng Lao-[Kaishan Fist].

Thinking of the scene when Feng Lao threw the fist technique to him indifferently, and said that this was the lowest level garbage he had, Yeyang hated it so much, the best magic of the spirit level, even he only had less than ten copies before.

With Yeyang's current strength, he can't fully exert the power of the Kaishan Fist, and the nine-style boxing method has only been cultivated to the fourth form, but even so, its power is also very amazing, and this high-speed hematite was shattered by him by one-tenth in two hours.

Retracting his slightly red and swollen fist, Yeyang walked to the pile of bricks and sat down, picked up a limestone brick, took out the black iron halberd and began to engrave, this black iron halberd was given to him by Feng Lao later, it weighed five thousand catties, and the previous gray stone bricks had long been used up, and the current one was only three inches thick.

However, Yeyang still carved a piece in three hours, the handwriting was quite neat, and there were few cracks on the limestone bricks.

After carving, Yeyang got up and did not put away the black iron halberd, but walked onto the ice with the halberd.

Naturally, the ice surface could not have become smoother, and he could stand up steadily at this time, but the volume and speed of the falling ice cubes were larger and faster.

A hundred-pound piece of ice fell, and Yeyang took a step to avoid it, and then swung out a halberd with his backhand, just breaking it, but he also slipped backwards. Then two more blocks of ice of about the same size fell, and Yeyang swung his Darkiron Halberd again to meet them...... Half an hour later, he was smashed out by a thousand-pound block of ice, he patted the ice chips on his body, and left the plain.

Coming out of the plains, Yeyang walked into a large mountain and through the jungle. There was a big cave at the foot of the mountain, he picked up a stone of more than ten catties, kicked it and flew in, and an angry roar suddenly sounded in the cave.

A huge black bear ran out and saw the familiar annoying figure in front of it, and its eyes were filled with intense anger. This black bear is five zhang long, three zhang tall when it stands up, with rough skin and thick flesh, and huge strength, it is the true overlord of the second-grade brute beasts, and even some ordinary brute beasts who have just entered the third grade are unwilling to provoke it.

Yeyang fought with it no less than ten times, each time it was less than a hundred moves, and it would be covered with scars, fortunately, it was not fast, Yeyang cultivated the shadowless step of the Xuanjie Extreme, and he could successfully escape every time, this time, he broke through to the condensate and vowed to defeat it.

The black bear roared and rushed towards the night sun, and slapped it with one palm, and the latter [shadowless step] moved, brushing the bear's paw, and a big tree behind him was suddenly broken.

Yeyang moved to the side of the black bear, clenched his fists, wrapped a layer of black vitality on it, and smashed a fist on the black bear's back: "Kaishan Fist First Style!"

With a muffled sound, the black bear was not harmed at all, and without even pausing its body, it pounced towards the night sun, but pounced on a string of afterimages.

"Kaishan Fist Second Style!" "Yeyang hit the black bear's weak defense in the abdomen this time, and the black bear's body rolled and was knocked out a few feet away, but there was no substantial damage.

"Kaishan Fist Third Style!" Yeyang took advantage of the situation, more than a dozen fist shadows fell on the black bear's stomach, the black bear roared in pain, slapped out with a palm, Yeyang couldn't dodge, leaving three deep visible wounds on his chest, which were shot out of more than ten zhang, hit the mountain wall, and a mouthful of blood spurted out.
