"Senior Lei, I'm here. Lei Yu respectfully greeted Lei Ming's seniors.

"Hey, how did your momentum become so powerful? Great!" Senior Lei saw the change in him as soon as he saw the thunderstorm.

"Hehe, it's just some opportunities, nothing. Lei Yu said and walked into the cultivation room.

The content of the fourth jade slip "Introduction to the Law of Space" is slowly turning in the sea of consciousness of the thunderstorm, and after cultivating the "Secret of Refining Qi in the Dark Desolation", the sea of knowledge of the thunderstorm has expanded to a radius of tens or hundreds of miles, and it has also absorbed a huge amount of heaven and earth aura, and the divine consciousness is of course more powerful, and with the improvement of the divine consciousness, the understanding of the thunderstorm at this time has also made great progress.

"Introduction to the Law of Space", which tells the formation and construction principle of self-space, these theories, for Lei Yu's cultivation at this time, of course, are very difficult, very difficult, and it is impossible to remember them after reading them once.

Cultivation has not reached that step, these theories are like metaphysics, and they cannot be deeply understood at all, because the founder never thought that his theory was built in the cultivation to reach the realm of the Jindan period, at that time, after several qualitative leaps, the thinking can naturally keep up, and once prompted, you can realize it, but I didn't expect that the successor of Lei Yu, cultivation is only for the Qi refining period, "Summary" There are many things in it, and they don't consider the realm of cultivators at all, of course, this senior will never know that the people who are cultivating this theory of him now will have such a low cultivation.

The formation of self-space is an extremely important thing for cultivators, and the concept of the domain in the future is built on the theory of space, and with the self-space, when the cultivation is one step further, the realm will be reached, and then the space can be torn apart and the space transformation can be achieved, that is, the category of 'teleportation'.

The concept of space is the application of the principle of force field, when the cultivator uses his divine consciousness to lock within the scope of his ability, when the space wrapped by his divine consciousness exceeds a certain critical point, then his own space is formed, since it is his own space, then he can do whatever he wants, if he encounters an enemy, confined the opponent to his own space, then the opponent will only be abused and will only wait for death.

In the cultivation room, six years have passed, and the thunderstorm has chewed the contents of the jade slip word by word, constantly experiencing this mysterious and mysterious feeling, sometimes it seems to have grasped something, but for a moment, this feeling disappears again. Although this feeling is floating, Lei Yu knows that he is not far from success.

Putting down the cultivation of "Introduction to the Law of Space", Lei Yu spent more than four years to practice the sword movement style in "Qingxu Sword Technique" without stopping, and only after a while did he truly appreciate the essence of using the sword and the cooperation of momentum that the master had said.

"There is no end to learning, the skills that I thought I had mastered before are really just scratching the surface!" Lei Yu said secretly in his heart.

Zuihou, Lei Yu took stock and cleaned up what he had learned one by one.

The cultivation methods are: "Eighteen Recipes for Immortality", "Immortal Gate Qi Refining Foundation", "Star Cultivation Recipe", "Soul Searching Recipe for Setting Yuan", "Secret Qi Refining Recipe for the Dark Desolation", "Outline of the Five Elements Cracking Laws", "Exploration of Wind and Thunder Guiding Laws", "Introduction to the Laws of Time", "Introduction to the Laws of Space" and so on.

The cultivation ** are: "Stick Method Cultivation Technique", "Immortal Sword Technique Foundation", "Jianzhen Cultivation Technique", "Qingxu Sword Technique".

After cultivating the "Clear Void Sword Technique", he really realized that his current understanding of the way of the sword was really too superficial, and what he needed most was a high-level sword technique to more deeply understand the mystery of the "Clear Void Sword Technique".

"After you go out, you must find a high-level Immortal Sect Sword Technique Jade Jian from Sect Master Ding!" he thought to himself.

Thunderstorm came out of the cultivation room, and after saying goodbye to Lei Ming's seniors, he returned to the immortal tree, and Xiao Shi was also planning to wake him up.

"Senior Lei, the "Summary of the Laws of Space" has never been able to grasp the main point, so it has to come out. Lei Yu said.

"Okay, okay, okay, it's okay, take your time, and one day you'll catch it." Lei Zhenzi said with relief.

Greedily inhaled the special breath of life emitted by the Immortal Tree, the mood of the thunderstorm was much better, and the aura emitted by the Xuanhuang Spirit Vein was combined with the breath of the Immortal Tree, and that breath really made people feel too comfortable.

"Okay, I'm out, I'll talk to you again when I have time. Lei Yu said, walking out of the blood thunder bead.

"Thunderstorm, Elder Ma has sent you a message, asking you to go to the Great Hall of Immortality before you set off. As soon as Uncle Zhang saw the thunderstorm, he quickly told the thunderstorm about the transmission.

......

"Your cultivation is really tight, as soon as you come back, you will close your cultivation, and it is not easy to meet you. Master Su said with a smile.

"If you don't hurry up, it's too far away, hehe!" replied with a smile.

"It's really timely for you to go to the spar mining area this time, otherwise the Immortal Gate will lose a lot of spars, and let you come, just to meet you." ”

"This is what I should do, Master Su and Elder Ma, don't be so outward. ”

"With these spars, I want to give you the spars I owe to Shopkeeper Xu to pay him back on your behalf. Su said.

"Shopkeeper Xu, I've done it, you don't have to pay it back, the spar will be kept for the longevity gate in the future. ”

"This time I went to the 'Tianyue Cave', I have a copy of the reference map inside, which was left after the collection of the previous masters, it may be useful to you, but you can't let others know, this is a secret passed down from the Immortal Gate. Master Su said, handing over a jade slip, along with several pills and a distress charm, to Lei Yu.

"These pills have the ability to heal poison and heal wounds, replenish true qi consumption in time, improve divine consciousness, etc., and carry them with you just in case. Elder Ma said.

"Xiexie Su is in charge, Elder Ma is here. Lei Yu thanked.

"I won't leave you, go back and prepare, and set off the day after tomorrow. ”

Halfway up the mountain behind the Great Hall of Immortality, there is a very special place, for hundreds or thousands of years, the masters of the Immortal Gate have been blessed with extremely powerful formations and prohibitions, and no one can approach it, which is the location of the mysterious 'Tianyue Cave'.

For thousands of years, the Immortal Sect has been passed down from generation to generation, leaving behind the legend of 'Tianyue Cave'.

It is said that thousands of years ago, due to the great changes in the aura of heaven and earth in the human world, the cultivation realm of human beings fought endlessly for the dwindling spiritual veins of heaven and earth, and the sects of the cultivation realm were almost completely wiped out.

The predecessors of the Immortal Sect, in order to continue the sect, opened up a mustard seed space in the spiritual vein of the back mountain, and connected it through a passage called "Tianyue Cave".

It is briefly opened every fifty years, so that the best of the descendants of this sect can have the opportunity to go to this mustard seed space, and absorb the aura of heaven and earth in that primitive environment that has not yet been destroyed, so that cultivation can make a rapid breakthrough.

It is said that those who are destined can even see all kinds of scenes and characters in the heyday of the human cultivation realm back then, and get some of the predecessors of the Immortal Sect back then, all kinds of cultivation**, cheats, instruments, pills, etc. left behind when they flew into immortals.

Because it can only be opened once every fifty years, the cultivation of disciples who can enter is also limited to the Qi refining period, and the disciples who cultivate in the foundation building period and above have tried countless times, but they can't enter at all, and they are all automatically blocked out of the cave, and they can't enter the mustard seed space.

The current boss of the sect is also because when he was cultivating in the Qi refining period, he went in once as an excellent disciple.

Because the mustard seed space is too large, it is comparable to a continent. When I went in, I was limited to a low level of cultivation, and I was only randomly sent to a very limited number of places, and it was impossible to get a glimpse of the whole space.

According to rumors, the items left in the mustard seed space are the agreement of the great power and predecessors of the Immortal Sect: "Before ascending to the immortal realm, or before passing away, all the items that you can't take away will be left in the space, so as to benefit the descendants of this sect, help future generations grow, and let people with virtue and talent and destiny get it, and inherit and glorify this sect."

Legend has it that this space is extremely mysterious, and there are countless hidden things, if you really have the fate to get it, don't say that you can dominate the Immortal Sect, even if you dominate the cultivation realm of the entire continent, it is not impossible, after all, it is the items, cultivation cheats, ** and cultivation experience left by the ancestors of the Immortal Sect before they ascended to the immortal realm!

It's just that those who can enter, their cultivation is only limited to the Qi refining period, it may be that the ancestors considered that the disciples in the Qi refining period, although their cultivation is low, they are more malleable, which is more conducive to accepting inheritance and more conducive to cultivation.

For more than a thousand years, countless outstanding disciples have traveled to this mustard seed space. Of course, most of the disciples who went there just saw the rich aura of heaven and earth in that space, and found some pills, elixirs, spirit grasses, ** cheats, cultivation equipment, etc., and the gains were not the same, and they had nothing to do with the level of cultivation, purely by chance.

Of course, there are gains and losses, and blessings and misfortunes depend on each other. There are many disciples who have fights and vendettas due to the various formation prohibitions, spirit beasts, dangers, and the things that have been obtained by each other due to greed, hatred, and mutual robbery, etc., and the vendetta has been left in it forever.

There are also some smart people, such as several leaders, including the current Su master, who have gained a lot from it, and thus stood at the peak of their sect.

Today, on the day when the 'Tianyue Cave' is about to open, the giants of all sects are planning, thinking about the situation that their sect disciples may encounter after entering, and how to get the maximum benefits.

However, there are too many variables in it, and it is a random teleportation, and it is completely impossible to control where it is teleported, and it is all up to personal chance, even if you want to worry about it, it is not much use.

In the main hall of the Purple Xuanfeng Sect, the disciples who will enter the 'Tianyue Cave' tomorrow gathered together to listen to the three elders introduce their experiences after entering the cave back then, as well as what they saw and heard.

After the merger of the two sects, this time the Purple Xuanfeng Sect, including Lei Yu, a total of forty disciples were eligible to enter.

“...... , Any prohibition that cannot be broken, don't forcibly destroy it, don't delay time, maybe the organs inside will cause you harm.

Each of you has a contact flame stick, once you go in, try to gather together as much as possible to reduce the risk, and in addition, you can find the treasure together, maybe the chance is greater.

Because it's a random teleportation inside, I don't know where you'll be teleported, the shape of the entire mustard seed space, probably the picture I drew, and you know your approximate location by comparing it to the stars.

In a word, it is good to find a treasure by chance, but life is more important, and it is best to come back alive and safely. Sect Master Ding Zuihou concluded.
