In the Demon Slayer World, Luo Men arranged for the Kamado family to move to a safer location through the Demon Slayer Corps. After asking Tanjirou for his preference, he also arranged for Tanjirou to learn Flame Breathing.
While Tanjirou could learn Sun Breathing, his compatibility with Water Breathing was far lower than with Flame Breathing. Learning Flame Breathing would allow Tanjirou to grow faster, and it wouldn't be as difficult to switch to Sun Breathing later on.
Nezuko also entered a state of slumber, seemingly undergoing some kind of transformation. This left Luo Men with enough time to search for Tamayo and begin developing the human-transforming medicine.
However, Luo Men had already decided not to repeat his past mistakes. If something could be stopped, he would absolutely not let it happen again.
As Luo Men embarked on his journey in the Demon Slayer World, his Marvel main body once again connected with a projected self.
This projected self had entered that world through projection reincarnation a while ago, when Luo Men had a little free time and the power of the Mirror Dimension had recovered somewhat.
Due to the Mystery of the Womb, that Luo Men only unraveled it after an accident not long ago.
Looking at the old man on the chair before him, who had lost the breath of life, Luo Men only unraveled the Mystery of the Womb under the impact of intense emotion.
Great Sage Xianren, Left Ruotong, Inverse Life Triple, and Wu Gensheng—Luo Men naturally knew where this was.
Luo Men, in this life, was just over twelve years old. He was found by Left Ruotong in a well during a time of war when he was born. He then followed Left Ruotong from a young age, learning from him, and by the age of twelve, he had already mastered the first stage of Inverse Life Triple.
However, because his master, Left Ruotong, had been diligently cultivating in seclusion today, he hadn't had the chance to inform him.
Once his master came out of seclusion, he would confront Wu Gensheng, then break through to the third stage, and finally, unable to cope, choose to end everything.
"Master, you still got stuck in a rut."
Looking at the old man who had passed away sitting in the chair, Luo Men couldn't help but murmur softly.
Because Wu Gensheng was able to neutralize Left Ruotong's Inverse Life Triple, Left Ruotong believed that the path of Inverse Life Triple was mistaken.
Luo Men didn't think there was anything wrong with Inverse Life Triple. The path to heaven wasn't limited to three stages, so Inverse Life Triple didn't necessarily have to be limited to three stages. The path is walked by people; the path opened by predecessors might be like this, but future generations can completely further develop the path.
Secondly, the most important point was that whether it was Left Ruotong or the current disciples of the San Yi Sect, everyone excessively pursued methods, thereby neglecting the improvement of their own life essence.
The essence of cultivation in this world was primarily the process of enhancing one's life essence.
If everything was transformed into Innate Qi, then without the life essence body as a foundation, how would it be different from a wisp of clear breeze between heaven and earth?
There was a very high possibility that Inverse Life Triple was not a complete method from the very beginning.
Luo Men believed that Inverse Life Triple, returning to its essence, still needed to focus on improving life essence, and the method of reversing back to Innate Qi should be supplementary, and it should be a means derived while improving life essence, just like the Golden Light of the Golden Light Charm.
Once the life essence grew strong and one's Qi underwent a certain qualitative change, it would no longer be like a gentle breeze without support, dissipating into the world if not fully concentrated.
It was like the True Yang Spirit of Quanzhen, transforming from the Yin Spirit, and reaching the Yang Spirit stage was a qualitative change. From being fragile to freely roaming the world, the difference was self-evident.
Left Ruotong's three states were like a Yin Spirit without qualitative change. The true third stage should still require a process of qualitative change, but Left Ruotong used external forces, rather than his own life essence reaching the standard, which is why it was like this.
However, the path of Inverse Life Triple had not been explored and perfected by predecessors, so Luo Men could only do it himself.
"But, isn't this also very interesting?"
However, after thinking about the cultivation after Inverse Life Triple, Luo Men suddenly got a headache again.
It wasn't because of cultivation problems; Luo Men had no issues with cultivation. Not to mention being influenced by Left Ruotong since childhood, the numerous materials left by Left Ruotong were enough for him to review.
Aside from cultivation, the problem was the senior uncles and brothers of the San Yi Sect.
Although his master had instructed them not to seek revenge on Wu Gensheng, under emotional impulses, no one would certainly obey this command. And those who had only shallowly cultivated Inverse Life Triple would be completely countered by Wu Gensheng, who possessed Divine Spirit.
Then, in the future, all the remaining people of the San Yi Sect, during the Jiashen Rebellion, led by Lu Jin, sought revenge on Wu Gensheng, resulting in their complete annihilation, with only Lu Jin surviving, and he failed to save his good brother.
However, there were still four years until the Jiashen Rebellion, and Luo Men had enough time to grow stronger and then consider how to proceed.
Since he had unraveled the Mystery of the Womb and knew a bit about the future's trajectory, Luo Men certainly wouldn't let everything follow its original path; he didn't like tragedies.
After seeing some of his senior brothers leave the San Yi Sect to seek revenge on Wu Gensheng, Luo Men did not stop them.
At present, his words carried little weight. He would discuss other matters after his strength improved and he had enough say. Most importantly, when Lu Jin gathered the San Yi Sect brothers in the future, he needed to have enough say, or enough strength, so that when they sought revenge on Wu Gensheng, they wouldn't be annihilated.
After Left Ruotong's ascension, after a period of turmoil, it finally slowly stabilized when a respected senior uncle stepped forward.
Luo Men looked at Lu Jin, a handsome young man in his twenties, whose constantly changing expressions showed that his inner state was quite poor at the moment.
After observing for a long time, Luo Men no longer stayed and returned to his room.
Next, he would improve Inverse Life Triple according to his own ideas.
Fortunately, Left Ruotong was formidable and collected many useful materials, and these things would ultimately be transformed into Luo Men's foundation.
"However, the Breathing Technique of the Demon Slayer World also seems to have some merits."
While studying the Qi refining methods in Under One Person, he discovered that the Breathing Technique of the Demon Slayer World could also be integrated into the Qi refining system, and he began attempts that would not harm himself.
Inverse Life Triple had parts that enhanced life essence, but compared to the methods of reversing to Innate Qi, it was still far inferior. This was a certain degree of asymmetry that led to the flaws of Inverse Life Triple.
However, the Demon Slayer Breathing Technique, to some extent, could also be considered a dual cultivation method of essence and life. Transparent World was essence, and Mark was life. Combined with Inverse Life Triple's own dual cultivation of essence and life, it could be further improved
