The old man lay lazily on the Taishi chair, and stretched out a hand to swing at Shen Luo.

The meaning was obvious and told him that he could leave now, and Shen Luo turned around and left very interestingly when he saw this.

After leaving Lingyun Pavilion, Shen Luo did not fly directly in the direction of the cave he had rented just now.

Instead, he returned to Black Wind City, where he wanted to buy some magic circles to protect the cave, even though he now had the Upside-Down Five Elements Array in his hands.

But in the final analysis, this is not where the sect is, and there is not enough security, so it is natural to be more careful.

The Smoke and Rain Pavilion is the most famous shop in the Black Wind City that sells all kinds of array flags and formation plates.

It is said that the shop was once founded by a monk of Jindan Daesei, and has a history of nearly 1,000 years.

Shen Luo walked into this shop wearing a grimace mask, and as soon as he stepped inside, he was attracted by the various array flags and magic plates placed on the counter.

However, he could only look at it curiously, he didn't know anything about the formation, and he didn't know what these tools were for.

"I've seen my seniors! I don't know what kind of formation my predecessors want to buy? We can sell various formations for attack, defense, illusion, and so on. A girl in yellow stepped forward and saluted Shen Luo, and said in a gentle voice.

"I want to buy a set of magic circles to protect the cave mansion, preferably one that even the Jindan period monks can't break at the first time!" Shen Luo said to the girl.

"Is it a magic circle that even a Jindan stage monk can block?"

When the girl heard this, she was stunned and stunned on the spot, she thought that the other party was just here to buy some ordinary formations.

Who would have expected that his lion opened his mouth widely, and he actually wanted to buy a magic circle that could block the Jindan period monks.

It took a while for the girl to recover from her shock.

"The little woman doesn't dare to call the shots for this kind of magic circle that the seniors want, and ask the seniors to wait for a while, the little woman will report this matter first, and then let the shopkeeper here decide." The girl said apologetically.

With that, the girl turned and walked into the inner hall behind the counter.

Seeing the girl walking away to report, Shen Luo had to stop in the store and wait.

The reason why he wanted this formation was nothing more than that he was afraid that in the cave mansion, he would use a gourd to refine the best elixir, or swallow this elixir to cultivate, and he would be noticed by outsiders.

After all, there are other monks living near his cave mansion, and he has to guard against this.

Not long after, the departing girl led a middle-aged beautiful woman to the hall.

"Do you want to buy a magic circle that can resist the Jindan monks in a short period of time?" As soon as the beautiful woman came here, she asked Shen Luo again.

"Yes." Shen Luo nodded.

"To be able to resist the magic circle of the Jindan period monk in a short period of time, our store naturally has it, but the refining materials of this magic circle are quite rare, and the refining method is extremely complicated, so the price." As she spoke, the beautiful woman stopped talking, but looked at Shen Luo with deep meaning.

"As long as the formation is applicable, the price is easy to say." Shen Luo said lightly, he dared to come here to buy the magic circle, he must have brought enough capital.

The capital in his hands was not earned by him selling pills and talismans, but by killing people and looting treasures from them.

"Since Daoyou is so refreshing, then I will also open the skylight and say something bright, there is a spell in our store called the Xuanhuang Yin and Yang Array, which is simplified according to the ancient array, and it is a complete defensive array."

"Even if it is a Jindan early stage cultivator, it will take half an hour to break it under a frontal attack."

"I didn't expect your store to have this kind of magic array, it's just a simplified version of this ancient array, and it should be quite time-consuming to arrange." Shen Luo held his chin with one hand and said slowly.

"Hehe, you can rest assured that the formation is very simple to arrange, and after several improvements by us, as long as the spirit stone is embedded in the formation plate, it can be activated." The beautiful woman smiled a little smugly.

"I see, I just don't know what the price of this formation is?"

"In terms of price, Daoist friends only need to deliver three thousand spirit stones."

Hearing this, Shen Luo didn't hesitate at all, and took out thirty middle-grade spirit stones from the storage bag.

Seeing Shen Luo so simply, the beautiful woman and the girl couldn't help but be very curious about his identity.

You must know that 3,000 spirit stones is not a small amount for a late-stage foundation building monk.

Shen Luo didn't even blink his eyes, and took them out.

Of course, their suspicion of Shen Luo can only be put in their stomachs, if because they talk a lot, the other party discourages the idea of buying, it will be more than worth the loss.

After Shen Luo delivered the spirit stone to obtain the formation, he bought some materials for refining talismans in the city, and finally flew towards his cave mansion with the flying boat.

When he came to the place where he rented the cave, he pushed open the bluestone gate that had been closed for a long time and walked in.

After a little inspection, Shen Luo arranged the upside-down Five Elements Array placed in the storage bag and the Xuanhuang Yin-Yang Array that he bought.

Seeing that these two magic circles were activated, he came to the retreat room with peace of mind and meditated and cultivated.

Time flies, time flies, and four years have passed unconsciously.

Shen Luo has been staying in the retreat room since he came to this cave mansion, concentrating on cultivation and never going out.

One day, Shen Luo, who was cultivating in the retreat room, suddenly interrupted his cultivation and opened his eyes.

After four years of retreat and cultivation, he meditated and cultivated with the help of the best elixir in his hand for four years.

Finally, the cultivation was forced from the late stage of foundation building to the late stage of foundation building, and it was only one foot away from forming a golden pill.

But with this kick, he couldn't get past it no matter what, and he knew that this was because of the bottleneck of Yudan.

As for the bottleneck of the Jie Dan, he currently only has four Dust Reduction Pills in his hand, and he only has four Dust Reduction Pills, so he doesn't dare to take them rashly.

On the one hand, he was afraid that his qualifications were too poor, and the four Dust Reduction Pills were not enough, and on the other hand, he was still short of the Snow Spirit Water and Heavenly Fire Liquid that he used when he was promoted to the Jie Dan.

These two kinds of spiritual liquid are indispensable elixirs, and their effects are equivalent to those taken by Qi refining period monks when they advance to the foundation building.

Shen Luo's own situation, he couldn't be clearer, he didn't think that after he broke through the bottleneck of the knot pill, he would definitely be able to rely on his own mana to advance to the Jindan successfully.

Therefore, without enough Dust Reduction Pill, Snow Spirit Water, and Heavenly Fire Liquid in hand, he would not easily get the Dan.

"If you want to get these elixirs as quickly as possible, you can only go to the Black Wind City Market." Shen Luo muttered to himself.

A few days later, the gate of the Bluestone Cave Mansion, which had been closed for four years, was finally opened.

Shen Luo drove the flying boat and flew straight in the direction of Black Wind City, flying at great speed.
