Looking back at the way he came, Ye Ning's face showed a look of astonishment.

The position where he was standing was like an acute angle cut diagonally, and there were already thick clouds rolling overhead, and they were constantly surging inland, and the speed was obviously much faster than on land, like a bowl buckled upside down on the ground, and the position where Ye Ning was standing was on the edge of the bowl.

He didn't know what the force that stopped the black mist from surging to the land was, but it was obvious that although this force was strong, it was obviously a little weak, and it was only a matter of time before the black tide poured into the land.

Ye Ning didn't get to the junction or break into the black fog to experience it, and didn't even study the interest of the black fog, he directly took out a jade talisman, and flicked it, the jade talisman turned into a faint white light, and shot into the dense fog in the blink of an eye, and then Ye Ning cleared: "Hurry!" ”

An earth-shattering explosion thunder came from the rolling black fog, and in the void dozens of miles away in front of Ye Ning, a round of dazzling brilliance suddenly appeared, like a scorching sun, endless thunder and lightning burst out, turning into a sky full of lightning, like a super huge firework, each trace of lightning extended out for tens of hundreds of miles, and where it passed, it was like a ray of sunshine that tore through the night, turning all the thick clouds and black fog into green smoke.

Not only the lightning, the thunder was everywhere, the black fog within a radius of hundreds of miles disappeared in an instant, and the night sky, which had already reached out and could not see the five fingers, suddenly appeared a full moon, a faint clear light sprinkled down, the moon was white and the wind was clear, where was the black fog surging?

Ye Ning stood in a daze for more than half an hour before he slowly came back to his senses, not because he was shocked by Fang Cai's vision, but because of the earth-shattering thunder, it was really too close. I almost deafened myself, and until now my head is still a little dizzy, which is too amazing, I didn't expect such a loud sound before, and I almost put on an oolong. Hurt yourself.

The effect of the jade talisman is much better than he imagined, not only the electric rays, but also the thunder is also the nemesis of those netherworld black mist, the only thing that makes him feel a pity is that the power of the heavenly thunder jade talisman is enough. But it's a bit thankless to do this kind of thing, and the scope that can be cleaned up is really limited, and as this breath dissipates, those endless black fogs will come back again.

Without even looking at it, Ye Ning already knew that those black mist were composed of endless Yin Souls. If they really let them pour into the continent and cover the sky, the inland will also be called a ghost domain.

Without rushing to leave, Ye Ning sat down on the top of the mountain with his knees crossed, it was night. He wanted to know what was going on with those ghosts under the scorching sun during the day, but at this time, he had no hope of using the heavenly thunder to completely dispel the so-called Netherworld Qi. This method can only keep one city and one place from being disturbed, and want to clean up the netherworld qi of the entire world. It's simply not realistic.

As expected, before dawn, a faint black mist began to appear in the area that had been cleaned up, and above the sky, black clouds had already covered most of the sky.

I couldn't help but make a move. Ye waited quietly for a few hours, until after dawn. Ye Ning just looked around, and then a wry smile appeared on his face, and his heart couldn't help but sink slightly.

The situation was much more difficult to deal with than he imagined, it was already more than ten o'clock in the morning, but the sky was still gray, the sky seemed to be dusk, the visibility was only forty or fifty meters, and it was foggy and unclear to see farther away, and the situation at sea was even worse, and it was impossible to see anything clearly in the distance.

Let go of the divine sense, the void shadows are full of cold energy masses floating around, needless to say, they are all ghosts with no wisdom.

Sighing secretly, Ye Ning simply took out all the remaining three Heavenly Thunder Jade Talismans in the storage space, raised his hand and threw them into the sky, and in a blink of an eye, the three jade talismans disappeared into the void, Ye Ning Qing snorted, "Hurry!" When he ascended above the sky, a series of explosions sounded, endless lightning scattered, and the rolling thunder went straight through the sky.

…,

This time it was much better than last night, as far as Ye Ning could see, the sky became clear in an instant, and there was not even a trace of light clouds, the warm sunlight sprinkled all over this side of the world, giving people a warm feeling, the cold energy mass floating in the void also disappeared dry and quiet, the breeze blew, and a faint smell of the sea could be smelled, a few minutes before and after, the same place, but it was like two completely different worlds.

Instead of continuing to stay here and do useless work, Ye Ning sacrificed Xingyao, turned into a faint nebula, and disappeared from the spot in the blink of an eye.

What Ye Ning didn't know was that less than ten minutes after he left, two figures appeared on the top of the mountain he had just stood on.

Back in Nanping, Ye Ning just explained to Cao Na and Fang Ping separately, and then escaped into the secret realm and disappeared again.

Ye Ning did not stay in the basin of the secret realm, but escaped into the depths of the secret realm.

Having explored the secret realm several times, Ye Ning also had an impression of the general situation of the secret realm, how big this secret realm is, he has not figured it out now, and has explored thousands of miles in several directions, but he has no clue, although the harvest is huge, but he has not explored the end of the secret realm.

This time, he naturally didn't want to continue to explore the end of the secret realm, but purposefully rushed to a place, a piece of cave blessed land that he had found during his previous explorations, and it was still more than two thousand miles away from the basin he had set up at the entrance.

This is an extremely deep valley, the rich aura of heaven and earth is almost condensed into a liquid state, strange flowers and plants compete for beauty, like a fairyland, it is in this valley, Ye Ning was abused by a spotted leopard to death, almost gave away his life, and did not even have a chance to escape, if it were not for the fairy sword Xingyao, Ye Ning would have to be reincarnated again.

Any kind of medicinal herb in this valley, put into the outside world, will make Ye Ning compete for it at any cost, but here, like the weeds outside, can be seen everywhere, the pure world blue lotus that is ready to be used to plant spirits for Cao Na was collected in this valley, which shows how attractive the natural materials and earth treasures here are.

Ye Ning came over this time, but it was a treasure in the old nest of the spotted leopard, a heart-cleansing cold spring known as the elixir and jade liquid in the immortal cultivation world.

He has already thought clearly, since the Heavenly Thunder Fu can't achieve his goal, he can only pin his hope on the light of the pure world that Chen Ying said, there are two main medicines in the Zhuji Dan in this valley, and he has already brought the remaining main medicine with him, and there is no shortage of auxiliary medicines, even if there is no identical one, he can find a substitute, and he can refine the Zhuji Dan without leaving the valley.

The reason why he chose this valley, in addition to the safety aspect, the heaven and earth aura here and the heart cleansing cold spring are also a strong guarantee for him to impact the foundation, with the heaven and earth aura that is so rich that it is almost liquefied, he does not have to worry about the lack of vitality, and the heart cleansing cold spring can allow him to always maintain the most sober state, so as not to be invaded by foreign demons when rushing through the level.

The first thing to do is to refine the Tsukidan.

After collecting and processing the required medicinal materials one by one, Ye Ning entered the old lair of the spotted leopard, which is a natural karst cave, which is extremely wide, with a space of seven or eight square kilometers, but there is only one exit, and this is also the place with the strongest aura in the entire valley.

Ye Ning arranged a formation at the entrance of the cave, completely concealed the entrance of the cave, and set up another formation trap in the entrance of the cave, of course, this was arranged just in case, he has always been a cautious and cautious person, even if he feels that it is foolproof, he will still make some arrangements in advance, this kind of character has saved him countless times, and it has also made him lose a lot of opportunities.

Near the innermost wall of the cave, there is a four-foot square pool, above the pool is a black and a white stalactite, from time to time there is a drop of stone milk dripping into the pool, this is the cold spring of cleansing the heart, in the world of cultivating immortals, even if it is a drop of the cold spring of the heart, it can be sold at a sky-high price, but a deep pool of water is found here.

…,

Taking out two jade bottles with slender necks from the storage space, Ye Ning used a small spell to make the two jade bottles stand in the void under the two stalactites, and collect the stone milk into the jade bottle, where he has already collected nine bottles of stone milk.

Sit down in the open space next to the waterhole and take out the Dan furnace, Ye Ning plans to refine the Dan medicine on the spot.

There were a lot of elixirs in the valley, and Ye Ning's storage space also brought a lot of elixirs collected from other places, and the preparation work alone had been done for nearly a week, so when he started alchemy, he seemed to be in an orderly manner.

Ye Ning did not directly start refining the Zhuji Dan, but first refined a few furnaces of other pills, especially the Cultivation God Pill, and refined nine furnaces in a row, this thing usually consumes little, but when it is really needed, it is very fatal, and there is always nothing wrong with making more preparations.

After everything fell into place, Ye Ning began to refine the foundation building pill calmly, in order to be able to smoothly impact the foundation building, the materials he prepared were very abundant, more than ninety percent of the raw materials were collected from the secret realm, and the several spiritual herbs that Liang Hongyan had originally collected outside were found in the secret realm, and even far exceeded his expectations.

Seven days passed in a blink of an eye, Ye Ning is first three furnaces of Zhuji Dan were basically scrapped, after all, it was the first time to refine this thing, and it was not until the fourth furnace that two finished products were produced, perhaps thanks to the way he handled the raw materials, so the quality of the pill was quite good.

There were no further mistakes in the next few furnaces, and after refining all the medicinal materials in one go, Ye Ning obtained a total of twenty-four Zhuji Dan.

With Tsukidan, the rest is to rush the pass.

And one last more...
