"Yes, I think when Lao Tzu practiced this exercise, his cultivation was only in the early stage of building the foundation realm," the bronze tiger statue sighed, and then said, "Later, after my physical body was destroyed, I don't know how many years have passed, but I didn't expect to be able to see the exercises practiced back then." ”

The voice of the bronze tiger statue is full of desolation, telling a past that belongs to him.

"I see." The promise bowed slightly.

Xu Yu looked at the exercise, and an impulse suddenly surged in his heart.

"If you practice this technique again, will you be able to regain your strength from the past?"

"You want to buy this exercise?" The bronze tiger statue said, "This exercise is incomplete, only the upper part, and the lower part was thrown by me in the land of the West Sea. “

"Since you've practiced this exercise yourself, isn't it very easy to do it all over again?"

"How many memories do you think will be left in a few hundred years?" The bronze tiger statue's tone was slightly lower.

"Forget it," Xu Promise said, "I guess your cultivation was not very good at that time, in my opinion, your own cultivation exercises should be memorized to the extent that you memorize them like a stream, buy them and try them." “

The words of the promise made the bronze tiger statue fall silent.

After a while, the bronze tiger statue said, "There is no complete exercise on it, and I don't remember the content of the second half, do you really want to try it?" “

"If it doesn't work, then make more preparations, in case you don't know where to find the second half later."

Xu Yu picked up the iron box, pretended to look at it for a while, and then looked at the stall owner: "How much is this spirit stone worth?" ”

"Childe, you really have a vision!" The stall owner stepped forward very attentively and said, "This thing is recorded in a sheepskin scroll, and it must be a good thing, and the price is three thousand silver dollars!" “

"Three thousand silver coins......" Xu Yu frowned slightly, and then said: "Give you two inferior spirit stones." “

The stall owner smiled,

Xu Yu glanced at the stall owner, smiled lightly, put the Nine Luan Sword and the black box containing the Nine Thunder Fire Duel into the storage bag, and slowly walked towards the outside of the store.

At the same time, while walking, I transmitted sound with the bronze tiger statue.

"How do you feel now that you know that the exercises you practiced back then are now only worth three thousand silver coins, and you can even easily buy them with only two lower grade spirit stones?"

"It's just that there are no beads, Lao Tzu spent a lot of money to get it." Although the tone was a little flat, it could be felt from the trembling from time to time when he spoke, and the bronze tiger statue was actually not calm at this time.

Then, Xu Yu took out the parchment scroll with the Nine Thunder and Fire Battles from the iron box, walked to a corner, and took a general look.

When he looked at the contents, the image he had seen before came to his mind, which was an extremely complex formation that looked very complicated.

Where do you seem to have seen this kind of formation?

But no matter how much he thought about it, he still didn't remember when he had seen this kind of formation.

Compared to this, when I was in the Cloud Sky Sect before, when I was attacked by the Ten Thousand Poison Sect, the formation patterns on the formation laid by the other party were simply like the graffiti drawn by a child.

"Looks good." Xu Promise said secretly in his heart, and then reached out and took the exercise into his arms.

Suddenly, on a whim, what would happen if the formation patterns on this scroll were copied on the paper used to draw the formations?

He bought a piece of paper and a pen from a utility store in the south of the city, then placed the parchment scroll underneath and began to sketch out the patterns.

Promise's movements were extremely slow, each finger seemed to be nailed to the table, slowly but accurately tracing the pattern.

"At this speed, I'm afraid I won't be able to finish it in a day!" Promise pursed his lips and muttered to himself.

At this time, the bronze tiger statue on the side suddenly made a mockery.

"What are you kid thinking? The lines on it don't make much sense. The mocking voice of the bronze tiger statue sounded.

Promise ignored it and continued to draw the formation.

"Since you said that you have forgotten many things because of time, then this may be one of them, and since these formations are here, then there must be a reason why they are here."

"Hmph." The bronze tiger statue snorted coldly, "You just wait for all the useless work you do later!" “

"Whatever!"

As soon as the bronze tiger statue finished speaking, he heard the promise muttered as if it didn't matter.

The bronze tiger statue rolled its eyes and said no more.

Xu Yu didn't know the slander in the heart of the bronze tiger statue, and he was now engrossed in drawing the formation.

"There are nine layers in total, each layer is divided into six levels, and the formation on the first floor is the simplest, but it is still not something I can crack now."

"But I can vaguely feel that these are indeed not formations, but a kind of ......" Xu Yu frowned and pondered for a while, and then patted his head, "It's more like a puzzle than a formation." ”

"What is hidden behind this is indeed very strong, but it's a pity that I have only cultivated to the peak of the early stage of foundation building now, if I want to crack what the content is, I should need to raise it to another level." Promise secretly.

Thinking of this, a doubt arose in Xu Promise's heart.

Could it be that there are other secrets hidden in these nine thunder and fire duels?

"Don't think about it, it's useless." The bronze tiger statue spoke again, "In the past, Lao Tzu cultivated this Nine Thunder Fire Technique to perfection or even perfection within a month, and naturally tried to crack these lines like you, but the subsequent conclusion was that the things inside were all written blindly. ”

"Nonsense?" Xu raised his eyebrows slightly.

"Yes, it's just like making it up, the patterns inside are all messy things, do you think Lao Tzu is idle? Will you scribble on some patterns and leave the information you want? "

"If you don't believe it, even if you crack it, you'd better not memorize those patterns, otherwise when the time comes, you will go crazy and die, and Lao Tzu won't know how to explain it."

"Confession?" Xu Promise was puzzled, "Explain to whom?" "

The bronze tiger statue smiled, did not speak, but looked at the jade Jian in Xu Xu's arms, "You still don't have to think about the meaning behind these lines, honestly practice the exercises in it, if Lao Tzu remembers something, at least he can give you a little guidance." "

Promise moved in his heart, but still shook his head and refused.

"Forget it, I can find the clue to this sheepskin scroll myself, and I won't bother you." Promised.

Hearing this, the expression on the bronze tiger statue changed a few times, and finally sneered: "Since you don't want to, there's no way." "

The promise snorted, and continued to sketch on the paper.

After some copying, he promised to copy nearly half of those lines, but the rest of the parts were quite complicated, and it didn't take long for me to feel a little mentally tired.

Xu Promise stood up, glanced at the bronze tiger statue, and then turned to leave.

The bronze tiger statue stared at the back of the promise for a while, and then snorted coldly: "I don't know how to lift!" "

Xu Promise ignored the scolding of the bronze tiger statue and walked straight towards the south of the city.

After he walked away, the bronze tiger statue suddenly turned into a golden cat and followed Xu Promise.

"Hmph, stinky boy, when you cultivate to the point where you don't understand in the future, at that time, Lao Tzu will definitely let you kneel on the ground and beg me to tell you!" The bronze tiger statue snorted coldly.

"Meow~!" The golden cat let out a very angry meow.

He paused, then lowered his head and looked at the parchment scroll in his hand.

Before, he wanted to record all the content on it, not only to record it at first, but also to remember this pattern in his mind, but in fact, when the bronze tiger statue said that these lines were meaningless, he dispelled this idea.

Because these patterns look like the formation disks of some formations, or some other strange symbols, they don't have any aggression at all, and he is still in the refining stage, even if he learns this pattern, it can only be a waste of time.

Thinking of this, Xu Promise directly threw the sheepskin scroll in his hand into the space ring.

After that, Xu Promise did not return to the Cloud Sect, but continued to wander around the town.

He always had a feeling that there was something in this place that he hadn't found.

When he promised to inform the bronze tiger statue of his thoughts, it was not surprising that he was ridiculed by the bronze tiger statue again.

On this day, Xu Promise got up early and took out a pile of medicinal herbs that he had obtained a few days ago.

Promise first placed the herbs on the floor of the house, and then took out a bunch of herbs from the storage ring, and arranged them all neatly.

These herbs would be perfect if they could be grown and self-sufficient.

It's a pity that if the herb with aura wants to take shape, it won't go through ten or eight years, and maybe it won't even be in the growth period.

Moreover, within one year before this, the efficacy of the drug must also be guaranteed, otherwise the effect of the drug will be greatly weakened after a long time.

Xu Yu sighed, no wonder most immortal cultivators would join the sect, even if it was only a very small sect, its background was not comparable to that of ordinary monks.

"No matter, anyway, I have time now, let's study it slowly."

Xu Promise sighed, and then continued to study the herbs.

And while he was busy, something happened in the town.

In the middle of the town, a few people suddenly appeared out of thin air, and as soon as they appeared, they began to look around.

The group was dressed in a very peculiar way, they wore black cloaks that hid their faces, and they were extremely short, like ordinary peasants, except that their eyes were very bright, like a pair of eagles, exuding a sharp and sharp gaze.

As soon as these people appeared, they drove all the surrounding people and businesses away, and then ransacked all the houses.

After driving the people around, they went straight into a house.

The construction of this house is very different from the surrounding buildings, it is like a huge warehouse, surrounded by mountains, and there are many doorways, which looks eerie.

One of them took out a jade slip: "That person's name is Xu Promise, this is the man's appearance, which was engraved in the jade slip by the adult, find him out as soon as possible, life or death." ”

Another man took the jade slip and put it on his eyebrows, and as soon as the jade slip touched the skin, it emitted a soft light that turned into a point of light and disappeared.

"Big brother, don't worry, as long as he dares to appear in front of us, he will be better off than dead!" Another said.

......

Promise didn't know what was going on in the outside world, and was now immersed in studying the lines on the sheepskin scroll in his hand.

Although Xu Yu only had a preliminary grasp of some of the veins on the parchment scroll, he also benefited a lot from the process of studying these veins.

"Huh? There are two lines that go in different directions! "

Suddenly, Promise whispered in surprise.

On a sheepskin scroll, and it's two lines.

One of them is golden yellow, while the other is off-white.

Xu Yu looked at these two lines, and his heart was excited, "These are two veins, golden and gray-white veins and ravines, which seem to form a dragon shape?" "

Thinking of this, Promise's heart was pounding, and he took a deep breath before returning his attention to the sheepskin scroll in his hand.

"Two dragon veins?!"

Xu Promise muttered, "Could it be that what is recorded on this scroll is not the direction of the dragon vein?!" "

Thinking of it, he did it, promised without the slightest hesitation, and immediately began to study the scroll in his hand.

He first used his spiritual power to probe and cover all the movements of the two dragon veins.

It turned out that the veins of the two dragon veins were indeed different from ordinary veins, these two veins were round, with a straight line in the middle, and curved on the other side, as if they were an earthworm.

"What's going on?"

Xu Promise frowned and muttered.

Promise looked at it carefully for a while, but he couldn't figure out why the veins of the dragon vein appeared on the parchment scroll.

Xu tried several more times, but still didn't figure it out.

"Forget it, let's study the information first." Xu Promise shook his head, "Regardless of whether the original owner of this scroll has really studied this thing thoroughly, just from the words in it, it is also very valuable, and this thing is also a little strange." "

Thinking of this, Xu Promise focused all his attention on the veins of these two dragon veins.

And when the promised spiritual power probed into the two veins, it was found that there was a faint white mist shrouded in the veins of the two dragon veins, and these white mist were not pure energy condensation, but also mixed with some quaint and mysterious aura.

Thinking of this, a solemnity flashed involuntarily in the promised eyes: "I don't know what is hidden here, but my current realm is still too low, I'm afraid I can only see such a little thing." "

Promise put away the parchment scroll.

He stood up and stretched.

However, when Xu Promise turned around, he saw an old man walking slowly towards him.

The old man looked to be about seventy years old, with a slightly hunched body, an old complexion, slightly pale temples, and a little thin.

When the old man came to a distance of five meters from Promise, he stopped, he looked up and glanced around, and then his gaze fell on Promise.

At this time, Xu Yu looked at the old man with some surprise.

The other party gave him a strong feeling, far beyond the level he could understand, and even more terrifying than those demon beasts.

Promise can feel that there is a palpitating power fluctuating in the other party.

The fluctuation unnerved him.

"Be careful." The bronze tiger statue that turned into a kitten on the side jumped to the shoulder of the promise, "The killing intent on that person's body is very strong, and it is aimed at you." ”

"You're the promise?"
