Luo Xin cautiously approached the bronze door, but he didn't worry too much in his heart.

Although he had never come here before, this was a place where the three ghosts often came, and if there were traps and dangers that his three ghosts couldn't detect, it wouldn't be Luo Xin's turn.

A thin layer of ice is attached to the bronze door, which makes the color of the door lighter. The ice sealed the gap in the door, making it impossible to see anything from here, and the huge handle of the door was locked, and the lock was also sealed by ice.

Luo Xin approached again and took a closer look for a while, and suddenly reached out to cover the door!

I saw that his eyes were looking straight ahead, and there was suddenly no wind around him, and the torch in his hand was directly blown out!

"Burning Heart Fire!" A colorless wave of heat burst out from his palm, centering on him, drying all the frost on the ground around him, and at the same time, it instantly swept the copper door in front of him, and the surrounding ice also melted and disappeared at a speed visible to the naked eye!

As the ice melted, the lock on the gate gradually revealed, it was not an ordinary door lock, there was no place to insert a key on it, but only an intricate coat of arms.

Luo Xin's hand did not stop, he simply threw away the extinguished torch, and the free hand was strengthened, and another colorless flame shot out, but this time the colorless fire was soaring, directly melting the residual ice in the gap of the gate.

Seeing that the hindered ice layer disappeared, Luo Xin collected his strength and kept shaking his two hands, which were steaming because the temperature was too high, so the next thing was to solve how to open the lock.

The disciple who had just gone to the rear had not yet returned, but Elder Peng, who had received the news, came over, and he panted and said, "Lord Luo, this place is cold and poisonous, and it has not been ventilated for many years, so we have to go out quickly!"

Luo Xin said confidently: "Elder don't worry, Lord Three Ghosts, he has explained to me how to open this lock, and give me time to stick incense, but I have to trouble you to appease the disciples first." ”

Elder Peng glanced at him and bowed his head to each other, although his words were concise, they contained trust.

This is the trust that the two have worked together for many years.

"Then I won't bother you, I'll go and see the disciples in the back!" Elder Peng waved his hand to him, and without resting for a while, he walked towards the back of the team again.

Although he knew that Elder Peng was by no means so old-fashioned, Luo Xin couldn't help but worry when he looked at his swaying back.

If you want to discuss the real age, there is actually not much difference between Elder Peng and those 'ageless demon girls' of Baihua Peak, two hundred years old is just an energetic prime of life for a cultivator, but there is no doubt that being trapped here for fifty years will not only have an impact on him, and this is the same for everyone.

But if you want to say why Elder Peng changed into such an old man, you have to start from his personal preferences.

Luo Xinyou remembered how dashing this old man was fifty years ago, and although he was a resolute supporter of 'not using the rejuvenation technique', it did not prevent him from wandering around the cultivation realm in the slightest.

It's a pity that Old Man Peng suffered a serious leg injury during that encirclement and suppression, and since then, although he doesn't say it on the surface, Luo Xin has known him for a hundred years, how can he not see his depression? Seeing that Old Man Peng really lived more and more like an ordinary old man in the human world, until a few years ago, the three ghosts went out and brought back a child.

Elder Peng's current grandson is actually not related to him by blood.

He is a merry old man who has not yet started a family, and he has no heirs at all, let alone any grandchildren.

He himself said that he didn't want to leave offspring, because he didn't know that he would die in the fight one day, so he didn't want to bother to be responsible for anyone.

At that time, conflicts of all sizes in the cultivation realm would occur almost every day, and there were not a few people who had this kind of thought, even Luo Xin himself thought so, and then those who had a heart would find that since the Lan Yan Sect was involved in the turmoil of fusing demon beasts, the family formation rate of its members had greatly decreased.

And the seemingly ruthless old man Peng, when he later met a homeless child who also had no family, he took the initiative to stand up and take him as his grandson, and he was very pampered, and even spoiled him like this.

But to be able to work with such a person for 50 years is also a blessing in this life!

Luo Xin smiled and shook his head helplessly, although he was thinking about things, the movements in his hands were not ambiguous at all, and it only took a while to do the things that needed to be prepared for unlocking.

The things to prepare are also very simple, and they have been known for a long time.

This kind of lock is not difficult for him to open, because the way to unlock the lock has been taught to him by the three ghosts a long time ago, so that when he saw this lock for the first time, the answer was already coming out.

It was a lock with a strange metallic sheen all over, and the lock body was large, completely beyond the width of the bronze doorknob, which seemed a bit exaggerated, but this kind of lock used to restrict cultivators was made like this to make people think that it might really work.

This thing that seems to be a lock doesn't actually have a place where the key can be inserted, but on the lock body, it uses etching to leave a formation that seems to be natural, a formation that makes him stunned.

The composition of this formation is actually not complicated, even if he is not good at it, he will arrange it, it belongs to the entry-level of the Lan Yan Sect, but because it is unpopular, there are not many people who learn it.

But he still remembered it very clearly, because this was what the three ghosts taught him personally.

When Luo Xin first joined the Lanyan Sect, the three ghosts were just a stunning genius, he longed for freedom and was unwilling to be bound by the affairs of the sect, so it was difficult for everyone to see him in the sect.

Although he was often away from home, the formation enchantment was one of his few interests, so when he was not going out or in retreat, he would also teach this kind of course in the sect.

Luo Xin was fortunate to be his apprentice for a while at that time, but not because he was interested in formation, he just went to see the demeanor of this genius.

Luo Xin used his fingers to caress the lines on the lock body, and the method of dissolving the formation quickly revisited in his mind.

"The formation I taught you today is very simple, but at the same time it is also difficult, I named it the 'One to Ten' formation. ”

There was a burst of laughter in the school, and the young disciples at the time were amused by the funny naming of the three ghosts, but it also managed to attract the attention of the disciples.

The three ghosts of the year said leisurely, when he was young, he was domineering, no one dared to pick up his edge, and just a glance at the lecture could make the most naughty students shut up obediently.

Luo Xin was not naughty at all, he just didn't like this class, he just wanted to come and see the style of the idol, but when he listened to it, he was also attracted by the words of the three ghosts.

At this time, the three ghosts were like a real teacher, from the theory of the formation to the application in practice, all of which were in detail, but this was not enough to distinguish him from other teachers.

The greatest advantage possessed by the Three Ghosts was his genius comprehension and unique perception, a realm that was difficult for mediocre cultivators to achieve in their lifetimes, and another point was his rich practical combat experience.

At that time, the Lan Yan Sect had not yet given birth to the fusion technique, and the power of the sect was still weak, so those who could fight like the three ghosts were very popular in the sect.

That period of time can be regarded as a difficult period for the Lan Yan faction, because it had just taken root, but it was also a time when the various factions were blooming and competing to expand their fields and influences.

The three ghosts started the class this time because he had just gone out to punish the rural faction who wanted to steal resources nearby, and it didn't take much effort.

Although the battle continued, they all survived without danger, but the three ghosts who had won a lot of battles did not dare to be complacent, in his opinion, fortunately, with what they were in their hands now, they could not enter the eyes of those big sects at all, so they were able to survive until now, otherwise with the consistent ruthless methods of the Demon Sect, it would not be enough to rely on one three ghosts alone.

In addition to the three ghosts' cultivation of the Burning Heart Fire, his attainments in all aspects are not bad. Usually, he is also good at setting up various formations around the sect, such as some of the magic arrays in the sect that warn outsiders, but they are all from his handwriting.

In his opinion, the formation path is the fastest way to improve a person's overall strength, because the setting of most small formations will not be limited by the level of the individual cultivator.

Once the formation is set, most of the operation and activation are from the surrounding environment to absorb the aura, and the longer it is set, the stronger the circle will be because it absorbs enough aura.

Therefore, as long as the caster is careful and cautious enough, and keeps in mind all the factors to be taken into account when setting up the circle, he can also make a super strong circle!

At that time, the sect was facing the harassment of the strife of various factions in the vicinity, so he took advantage of this time to come back to rest, and simply started a class to teach the formation he had learned a few days ago to the juniors, which could be regarded as making some contributions to the sect.

Although the formation engraved on the lock can be seen with the naked eye, in order to crack it, you need to dive into the level that the maker left inside.

This seemingly simple and easy-to-learn formation, it is indeed not difficult to learn how to arrange it, but the way to crack it is difficult, this is the intention of the three ghosts to teach this method to these junior disciples, so that the enemy can be weak and strong!

Luo Xin probed his mind into 'one when ten', and a smile appeared on his lips.

The magic circle that appeared here was exactly the same as that of the Three Ghost Professors back then, and once his mind penetrated, several possible paths of life and death were all in front of him in an instant, but he vaguely remembered that many of them were deceptions left by the formation makers.

There is only one real life gate, and this door lock is not to trap the disciples here, this is a hint, the three ghosts have already given it to him fifty years ago.

The carving of 'One When Ten' is not complicated in the formation, it can even be said to be simple, but its simple lines contain great power, which is also a manifestation of the genius mind of the three ghosts.

But in the eyes of those who don't understand, 'one when ten' is just a simple primary formation, even if you can't find a way to live, it doesn't hurt to forcibly crack it.

This is another method of deception in this circle, using seemingly simple lines to trick the intruder into letting down their vigilance, but if they really force their way in, those strange true breaths that are instilled will immediately trigger the warning mechanism in the circle, warning the caster and causing the entire circle to change.

Somewhere the pattern will be transformed, turning this otherwise solvable formation into a dead formation, and into an offensive formation that amplifies power!

The strange true breath that invaded before will become the nourishment that fuels the magic circle, and it will be quickly absorbed and used in the formation, and then explode violently!

If this intruder had the intention of forcibly breaking through the formation, then the amount of true breath he poured into this formation would be very huge, which also meant that the power of the subsequent formation explosion would be twice as much as the amount of true breath he poured into it!
