Chapter 103 Reaching a Bottleneck

He asked Ye Tiannan for a computer and then moved in here.

He originally intended to leave this world directly, but the appearance of these secret manuals was an unexpected delight. Therefore, he naturally wanted to thoroughly understand them before leaving.

In the time that followed, because he had no interest in the points awarded by the ghosts, Meng Li became completely oblivious to the world around him, even more ascetic than a hermit.

Meanwhile, in an office at the headquarters of the Demon Slayers.

"Senior brother, he's an intruder, why don't we attack him?"

Next to Ye Tiannan, a girl said angrily.

Fang Xiandao was naturally not just Ye Tiannan; the person next to him was his junior sister.

"It's nothing. We became friends after our fight. Besides, he's very strong. If a vengeful ghost appears later, we might need his help."

"But this is too stifling."

"It's nothing. To slay the vengeful ghost and restore peace and tranquility to the world, what's a little grievance?"

Ye Tiannan affectionately patted the girl's head.

"Senior brother..."

Looking at Ye Tiannan in front of her, the girl's eyes were full of admiration, and faintly, one could also see a hint of affection in them.

However, their romantic atmosphere was quickly broken.

A burly figure knocked on the door and walked in.

"Then I'll go down first, senior brother."

Seeing that Ye Tiannan had important business to attend to, the girl left on her own.

Ye Tiannan nodded and looked at his subordinates.

"How's it going? Have you found anything?"

"We've found out."

After he finished speaking, the burly man in black handed him a file folder.

Upon opening the file, the portrait of the file's owner was none other than Meng Li.

"An orphan since childhood, orphaned at a young age, chosen by the Bureau of Ghost Control, disappeared while controlling a benevolent spirit..."

"Boss, is there something wrong with him?"

The middle-aged man looked at Ye Tiannan's solemn expression and asked a question.

He was also a member of Fangxiandao. Although he looked old, he was actually only three years older than Ye Tiannan. They had grown up together since childhood, but he was an outer disciple and did not address him as a fellow disciple.

However, this did not affect the close relationship between the two. The burly man was considered Ye Tiannan's confidant, and given their relationship, he directly asked the question.

"There's no problem, you can go now."

Ye Tiannan smiled and said.

After the other person left the office, Ye Tiannan tapped his fingers lightly on the table, a thoughtful expression on his face.

"Who exactly are you...?"

Ye Tiannan didn't believe a single word of the file, but the other person's life trajectory from childhood to adulthood was traceable.

If the possibility that the other party had deceived the entire world is ruled out, the only thing Ye Tiannan could think of was possession.

Possession isn't something you can just talk about; at the very least, you need to be able to separate your soul from your body. But in this day and age, he's never even heard of it, let alone seen it.

Just as Ye Tiannan was pondering his identity, Meng Li also put down the book in his hand, his eyes vacant.

Of course, although he seemed to have lost his perception of the outside world, his brain was extremely active at this moment, and he was deducing the feasibility of various rituals and spells in his mind.

His powerful mind allowed him to achieve a breakthrough in less than half a month, a feat that hadn't been accomplished in the world for several years.

Meng Li had never discovered that she actually had a talent for research, but this kind of thinking was too tedious. Compared to this kind of life, Meng Li still preferred the visceral combat of hand-to-hand fighting.

But the outcome was ultimately good.

As Ye Tiannan said, nine out of ten of these books require spiritual energy, but there are also dozens of books that do not.

Meng Li then identified several theoretically feasible techniques from these ancient texts.

However, I don't know if it's related to not needing spiritual energy.

These spells all carry a hint of evil, lacking the so-called celestial aura, and seem more like unorthodox or heretical practices. They don't look like righteous methods at all.

For example, giving people secret medicines, creating so-called heavenly soldiers and generals at the cost of shortening one's lifespan, or eating raw animal and human flesh and blood to nourish a bloodthirsty and malevolent energy in one's heart, etc.

Anyway, Meng Li glanced at them a few times and then put them aside.

High cost is only one aspect of them.

Meng Li did not consider himself a great philanthropist.

Unless these techniques are truly heinous and require something like a human brain or an infant's heart, he will learn them without hesitation as long as they are helpful to him, even if they simply involve the use of blood or food or the need to endure pain.

It's mostly garbage.

These spells are effective against ordinary people, but they can be taken down with a single shot from a firearm. It's a huge waste of effort for such a lackluster result.

This is probably why Ye Tiannan didn't study them at all, even though they seemed feasible. After all, their effects wouldn't even be considered useless in the era of vengeful ghosts.

Meng Li's research, however, focuses on their principles rather than their practicality.

However, he also hit a bottleneck at this time. These techniques were useful for reference, but not many. They were nothing more than using things like blood energy and medicinal power to replace spiritual power.

But here's the problem: this substitution has its limits. To enhance their power, one still needs to study spiritual energy manuals.

But here's the problem: he didn't have a sample of spiritual power and had no idea what spiritual energy was.

During his conversation with Ye Tiannan, Ye Tiannan also discussed spiritual energy, and Ye Tiannan speculated that spiritual energy had long since disappeared from this world.

According to him, he later communicated with those Golden Elixir sects. Compared to the Fangxian Dao, they were in a worse situation. It is said that hundreds of years ago, they could communicate with the Heavenly Ancestors, but now it is different. All their cultivation scriptures have become worthless.

This is another piece of evidence that he believes gods and immortals may really exist.

After all, Fangxiandao had no records, but the Taoist sects of Longhu Mountain and Shu Mountain did have records of people ascending to immortality. Although everyone later thought it was fake, after the appearance of ghosts and the fact that the secrets of Fangxiandao were really useful, the records of those Golden Core sects also became elusive.

Of course, there are many cultivation systems in this world.

Besides the orthodox Golden Elixir School, the Fangxian Dao, a heretical and unorthodox sect, actually contains truly evil paths.

However, their requirements for spiritual energy are no less, and those spells that do not require spiritual energy are not only more cruel than those of the Fangxian Dao, but also less effective.

"It seems we could explore other religious sects."

With the teleportation anchor point set, the future body ready, and the invincible shield still in place, Meng Li now feels completely safe.

The research on Fangxian Dao has now reached a bottleneck. Perhaps we should try to look at the classics of other sects. Maybe we can learn from their experiences.

Thinking of this, he sent a message to Ye Tiannan, intending to ask him about the relevant matters when he came over.

While waiting, Meng Li also took a good look at the room where she had stayed for half a month.

Even Ye Tiannan's understanding of the Dao of Immortals is far inferior to his own.
