After leaving the cave, Yi Chen headed all the way north, and the little stone man turned into a round stone pier again, and he put it in a storage bag.

Half an hour later, he came to a small city, which was out of the range of Tainan Mountain, and he planned to look for some more information about the map of the prefecture, although he had obtained a map of the prefecture from the old man Yunbai before, but it was incomplete, and its content was not the surrounding area.

But at this moment, it was late at night, there were not many places in the city where the lights were still on, and it was not the time to inquire about the news, after walking around the street for a while, Yi Chen walked into an inn, he planned to take a good rest, and he was a little tired from the toss of the ruins to the present.

"Open a room. After throwing down a piece of broken silver, Yi Chen said lightly, he didn't have much of these worldly belongings, and this was what Grandpa Zhang left for himself.

After a while, the guy led Yi Chen up to the second floor, stopped in front of the door of one of the empty rooms, and after entering the house, Yi Chen casually gave two orders to the guy, and then closed the door.

A wooden table, two square stools, a bed, no extra decorations, quite simple, the inns in the small city are not as ornate as the big cities.

When the divine consciousness unfolded, there was some movement on both sides of the partition wall, and the guest rooms on both sides of the place where Yi Chen was located had already occupied guests.

"Yu'er. With a wave of his hand, a divine sense barrier was struck, blocking out the movement coming from both sides, Yi Chen called softly, and when the words fell, the jade spirit poked out of his body, transformed into a human form.

"What do you think of that ancient ruin?" Yi Chen continued to speak, tossing all the way, stopping at this moment, and suddenly remembered the problem that he had temporarily ignored before.

"You mean the cave mansion outside the small world, right?" Although this inn looks simple, but the bed is quite soft and comfortable, sit down quietly on the side of the bed, gently leaning on the edge of the bed frame, Yu'er is beautiful, when she looks at Yi Chen, she purses her lips and says, she and Yi Chen have a heart-to-heart connection, and naturally know what the latter wants to say.

"Hmm. Yi Chen nodded, and then said, frowning slightly, revealing doubts.

"Judging from the Star Array outside the small world, it seems that the previous master of the Ancient Cave Mansion should also be a formation master, and the realm is probably not weak, but shouldn't the formation master be only available in Qingxuanbu Prefecture, how could he come to Yuxubu Prefecture?"

"The formation path was created by the Qinglong Demon Ancestor, during the First World War in ancient times, the Demon Ancestor traveled all over the world, even if it left a legacy in other states, it is not necessarily. However, Yu'er covered her mouth and smiled, and then said.

"Uh......" Yi Chen was stunned for a moment when he heard this, then he was relieved and nodded, he forgot that the Demon Ancestor was the founder of the Formation Dao, because Zhang Fan and the Formation Peak were in the same vein, he always had a preconceived idea that Qingxuanzong was the birthplace of the Formation Dao, but he forgot that Yu'er had told him about these ancient things in the prison realm.

"The Qinglong Demon Ancestor was born in Qingxuanbu Prefecture, and one of its most outstanding disciples is also from Qingxuanbu Prefecture, so naturally the formation division in Qingxuanbu Prefecture is more prosperous, but this does not mean that only Qingxuanbu Prefecture has formation divisions. Yu'er continued.

Hearing this, Yi Chen nodded lightly, feeling that it made a lot of sense, as for the most outstanding disciple of the Demon Ancestor that Yu'er said, he naturally knew without thinking about it that there would be no one else except Zhang Fan.

"Is it possible that there is also a lineage of formation masters outside the state of Qingxuanbu......" Slowly sitting on the square bench next to the wooden table, Yi Chen muttered, The ancient ruins, the Great Array of Heavens and Stars really shocked him a lot at that time, and now he suddenly understood when he heard Yu'er's words.

Whether it is the Demon Ancestor or his disciples, in that ancient era, all of them were at the pinnacle of this world, and it is not impossible to leave a legacy in other states, but it may not be like Zhang Fan who founded Qingxuanzong to continue this lineage.

However, this does not rule out the possibility that there are still formation divisions in other places outside the state of Qingxuanbu!

"If there are still successors of the other formation masters, if I am lucky enough to meet them, I would like to have a good fight. A bright light flashed in his eyes, and the corners of Yi Chen's mouth showed a slight smile, a little expectant.

He is the first line of the Qingxuanzong Formation Peak, and he is the only inheritor of Zhang Fan, so he is naturally more concerned about this aspect, but even the current formation master of the Qingxuanzong has only three people left, and I am afraid that the possibility of the existence of the formation master in other places will be lower.

"The reason why the owner of the Ancient Cave Mansion built the Cave Mansion outside the small world is probably because he discovered the remnants of the Nightmare Clan, so he destroyed it and sealed it again, since the Qinglong Demon Ancestor, the formation master has always been on the side of the right path. Yu'er said slowly, a little admiration flashed in her beautiful eyes.

Hearing this, Yi Chen nodded lightly, after entering the small world, he saw that there were many broken tree stumps and collapsed stone pillars in the ancient forest, and he could vaguely see that there had been a fierce fight in it a long time ago, I am afraid that the two sides of the fight were the Nightmare Clan in the stone hall and the master of the Ancient Cave Mansion.

"In ancient times, the formation master was much stronger than it is now. Yi Chen pursed his lips, was silent for a moment, and then sighed, the Great Array of Heavens and Stars made him feel very tricky, and he could only rely on the formation to crack it, and the Nightmare Clan with red pupils was a powerful existence that could open up a small world, and the master of the Ancient Cave Mansion could still kill him, which showed that the strength was terrifying, but unlike now, even the Qingxuanzong Formation Peak had only a handful of three people left, and even two of them were half-people like him and Yan Hao who had just stepped into the formation.

"Array Dao ......" Thinking of this, Yi Chen took a deep breath, and then groaned again, these two words had been carefully thought about when he fought with the stone giant, now he lacked means, except for the Spirit Melting Array and the Tribulation Array, the others were almost impossible to take, although these two things were enough to make him proud of his peers, but he still had to start thinking about adding new means, because at this moment, he had a sense of urgency, and this sense of urgency came from Taiyizi.

Born with a Dao body, that's an extremely strong opponent!

Moreover, he had agreed with Taiyi to fight in the future, whether it was to keep the contract or to borrow the teleportation array of the Ministry of State, he had to go to this battle, but with the existing means, to be honest, Yi Chen was not sure.

Even when it was to build the foundation to perfection, he was not sure.

Because the other party is a natural Dao body, who knows what realm the other party will reach when he breaks through to the consummation of foundation building?

Tong Xuan Period? Even stronger?Yi Chen didn't count it in his heart, but he knew that Taiyi would never be slow to cultivate!

But the consummation of the foundation is already the limit that Yi Chen can wait patiently, he is eager to return to the sect, and it is impossible to really delay until the day when he cultivates to be equal to Taiyi, therefore, in order to have some certainty in the future battle, he must add more and stronger means for himself!

But as for how to add new means, the only thing Yi Chen could think of was to start with the formation path.

Since the formation of the formation body was refined, he had also studied the formation path for a while, but the study was not deep, and it was only in the month before the trip to the prison realm, and the real gain was not great.

"But now if I work the formation path, I should be able to gain something. Pursing his lips, Yi Chen said to himself, his eyes showed a deep expression, he has experienced a lot in the past period of time, a hundred years of dream life and the conversation with Zhang Fan, he has gained a lot, a little precipitation, if he uses this to study and cultivate the formation path, there should be some results.

"The birth of the Tribulation Array can only be said to be an unexpected surprise, if I can comprehend a new formation this time, it will be my own formation. Yi Chen secretly said in his heart, nodded, his eyes were a little firmer, the Tribulation Intent Array was strictly speaking just that he used the trace of Tribulation Intent that was integrated into his body in the stone pillar space, and it happened to be combined with a formation that he imitated in the Endless Great Array, and it could not be regarded as the formation he comprehended, if he could gain something in the formation path this time, it would be completely his own efforts, and it could be called a real attainment in the formation path.

"Speaking of which, Yan Hao seems to have already realized a formation by himself......" Thinking of this, Yi Chen's eyes suddenly froze slightly, and then he shook his head and smiled helplessly, he had seen Yan Hao's self-created formation twice when Yan Hao was building the foundation and fighting the Jiao Beast in the deep valley of the prison realm, and the power was very good, if it was combined with the Spirit Gathering Array, it was almost not weaker than his Tribulation Array, but it was a little too terrifying in terms of consuming spiritual energy.

Yan Hao's guy obviously entered the formation through the back door, but he didn't expect that his attainments in the formation path were stronger than his who went through the front door......

"I also have to work hard, I am also the inheritor of the way of the Immortal Array Master of Sect Master Zhang Fan, I will see Yan Hao again when I return to the sect in the future, I can't lose to him in the formation path, it's too shameless......" With a long sigh, Yi Chen's eyes were certain, but a gentle smile appeared on his face, after the hundred years of life in the dream, he was even more looking forward to the reunion with Yan Hao in the future.

"It's late at night now, shouldn't you understand your formation path in this inn?" Leaning on the side ......of the bed, looking at Yi Chen's determined face at this moment, Yu'er covered her mouth and chuckled.

Hearing this, Yi Chen smiled calmly and shook his head, he naturally wouldn't be so desperate to comprehend the formation path, but his plans for future cultivation had to be thought about as soon as possible.

With an accurate goal and direction in mind, cultivating can also save a lot of unnecessary wasted time, but he likes to do everything with confidence and preparation, so as not to make what he does useless.

"There are also spirit stones, this is also a big problem......" And when it came to cultivation, Yi Chen suddenly frowned, and then sighed helplessly, speaking of which, this is the most fundamental and important problem at the moment, what he lacks most now is the spirit stone, without the spirit stone, only relying on the spirit gathering array he laid and the thin aura floating between heaven and earth, his cultivation is almost as slow as a turtle crawling, and it is impossible to step into the foundation building consummation in a short period of time, let alone go to the Taiyi Sect to find Taiyi to fight.

"How can I get a large number of spirit stones in a short period of time......" frowned slightly, Yi Chen pondered, but after a while, there was a look of distress in his eyes, he would never be less than the spirit stones needed to cultivate to the perfection of the foundation, and with his vision, at least a large number of high-grade spirit stones, even if he used medium-grade spirit stones to cultivate, it was too slow, he couldn't bear it, but how to obtain a large number of high-grade spirit stones, this was a big problem.

Yi Chen vetoed it at the first time, with his nature he would not do this at all, there was no injustice or hatred, why would he rob other people's spirit stones, besides, as far as he had seen so far, there were almost no reserves of rare cultivation resources such as top-grade spirit stones in small sects, and even in the hands of the scattered cultivation seniors of the Xuan Period.

A large number of high-grade spirit stone reserves can only be possessed by the middle immortal sect or above the family, but obviously, with Yi Chen's current strength, he is not qualified to provoke the middle immortal sect or family, that belongs to looking for death.

Of course, it is still the same sentence, there is no injustice and no hatred, and he has no reason to provoke others.

And apart from grabbing, there are not many ways left......

There are only two ways that Yi Chen can think of now, either he can sell all the valuable things on his body for spirit stones, such as the magic weapon of the net, Uncle Luo Zhen's storage bag, etc., and he will definitely be able to exchange for a lot of high-grade spirit stones, or he can only go to the mountains and deep valleys to find spiritual mines to dig by himself.

Neither method is really a good idea......

Frowning slightly, Yi Chen sighed, revealing a little helplessness, he really didn't know the price of firewood and rice, when he was in Qingxuanzong before, he almost never had any troubles about the spirit stone, and there was no spirit stone to reach out to the elder to ask for it, but now that he was in the Yuxu Prefecture, he had to think about this problem.

At the moment, obtaining spirit stones is more urgent for him than comprehending the formation path.

Yu'er leaned on the side of the bed, looking at Yi Chen with a distressed face at the moment, but she was also a little helpless, spirit stones were already scarce, if they were just low-grade spirit stones, it might be much easier to obtain, but obviously it was impossible to see with Yi Chen's vision.

Both of them were silent, and the room was quiet for a while, but at this moment, Yi Chen's expression moved slightly, and he noticed that there was a sudden movement in the storage bag on his waist.

"What's the matter with you?" The divine sense hooked the storage bag, took out the round stone pier, and put it on the wooden table, Yi Chen looked at the little stone man who turned around and appeared, and said calmly.

He put the little stone man into an empty storage bag, and Uncle Luo Zhen gave him a total of two storage bags, and the spirit stone magic weapon and other things were put in another storage bag, otherwise all the ten high-grade spirit stones he had would be stolen and eaten by this goods.

"You want spirit stones, don't you? Find me! I am a stone spirit clan, I can naturally sense spirit stone mines, how about taking you to mine?" Xiao Shiren looked at Yi Chen at this moment, with a smug expression, showing off his ability, as if he had forgotten his previous painful experience.

But Yi Chen didn't care about his attitude, when he heard the words at this moment, his eyes suddenly lit up, revealing a strong essence, and he quickly spoke.

"Can you sense where there is a spirit mine?"
