"This is an Advent ritual."

He Ao calmly looked at the lines around him with deep eyes.

"Advent ceremony?"

There was an obvious question mark on Luo Luo's face. As an extraordinary person, she suddenly felt that He Ao's knowledge structure was not on the same level as hers.

"Brother Hao Yi, what is the advent ceremony?"

Lin Chi Chi didn't feel that much. She basically didn't know anything, so she just asked questions directly.

"You can understand it as a 'channel' through which some high-level being that exists outside this time and space forcibly descends into this world."

He Ao squatted down next to the flesh and blood control console and carefully checked the surrounding circuits.

After entering the front of the car, those dark tentacles never appeared again.

This is an obvious protection mechanism. This car is very afraid that those tentacles that are not very controlled will destroy the ritual formation inside.

To be precise, the 'arranger' of this ceremony did not trust the tentacles belonging to this car.

In fact, from the moment he got on the bus, He Ao found that the rules of this car were a bit too complicated.

Of course, it is understandable that a B-level extraordinary item has extremely complex ritual rules. After all, under such a weird extraordinary system, anything can happen.

So Heao showed no obvious doubts.

Until he saw the blood pool in the last carriage and the ritual circle in the front of the carriage.

No extraordinary item would draw an advent ritual in one's body to summon other high-ranking beings, and the simple wisdom of extraordinary items would not be able to achieve such a complex function.

Obviously, this car was deliberately set up by a certain existence to complete the advent ceremony in the main world.

"High-ranking existence?" Lin Chi responded, "Is it a god from myths and legends? Do gods really exist in this world?"

After saying this, she suddenly realized that she seemed to have asked a very stupid question. There are trains in this world that can travel through space at will and travel thousands of kilometers in half an hour. Why can't gods exist?

"But, Yan..." Luo Luo glanced at He Ao, "The information I got is that there are no gods in this world..."

"It depends on how you define it. In a sense, 'gods' are some kind of powerful extraordinary beings, but they are indescribable and incomprehensible. They have gone beyond the scope of what ordinary mortals can understand, so they are considered to be

There’s nothing wrong with ‘god’ either.”

He Ao didn't look up. He was carefully tracing some of the lines in the car. He vaguely felt that these lines could overlap with the lines in the red beads he obtained from Jin Ya.

However, the two magic formations did not completely overlap. He was trying to analyze the meaning behind this overlap.

Luo Luo nodded thoughtfully. In the research institute's information, no extraordinary life that exceeds human cognition has been found so far, but the absence of discovery does not mean that there is no such thing.

One of the institute's tenets is, 'Always remain in awe of the unknown.'

But at this moment, she became extremely curious about He Ao's identity.

He Ao seems to know a lot of occult knowledge that even the academy does not know.

"Then this ceremony is the coming ceremony of a powerful 'god'?"

Lin Chichi glanced at the terrifying bloody lines around him with some worry, "Then can we still survive?"

Since He Ao has used that tone to describe "gods", it proves that the gods may be really strong, so strong that even He Ao cannot deal with them.

If this is really a trap from the gods, then I'm afraid the only option is to lie down and die.

"uncertain."

He Ao shook his head. He had vaguely separated the overlapping part of the two magic formations and was analyzing the remaining magic formations.

What makes He Ao still a little confused about this advent array is that it is too complicated.

As a 'friend of the gods' who has dealt with many friends, He Ao still has a little understanding of the rituals of the gods.

All the ritual formations of evil gods coexist with simplicity and complexity.

Simplicity lies in the fact that the emblems pointing to the gods are very simple. They are basically some simple compositions, such as the seven-pointed star of the God of Knowledge, the heart shape of the Desire Witch, and the Eye of Truth of the God of Death.

The complexity lies in the fact that these emblems have strict carving conditions. The more precise the carving, the more perfect the ceremony, the more pleasing the gods will be.

For example, a good friend particularly likes the magic circle arranged by He Ao.

Pattern is the language of mysticism. The simpler the emblem, the more unique this great being is.

Just like a person's title.

In ancient China, the emperor was supreme. When talking about the emperor, people knew that it referred to a specific person.

There are many "kings" under the emperor, so when describing a certain "king", you must add his feudal name or title, such as South Commandery King, North Commandery King.

The more accurate modifications required prove that there are many people of the same class of this character, and he has to modify himself to distinguish himself from others.

Of course, the actual character title modification involves many detailed changes.

But in a mystical sense, generally the more complex the pattern, the lower the level.

The magic circle in front of He Ao now is that the pattern pointing to the descending high-dimensional existence is too complicated, and it does not seem to be pointing to a certain god.

If it is a person whose personality is lower than God, it can be explained.

If you can use a B-level extraordinary item as the carrier of your own Advent Ritual, then your personality is probably higher than that of B-level, and there is no relevant knowledge in He Ao's memory that B-level can use the Advent Ritual.

Class B is still in the human category.

When it comes to ‘advent’, they all have a certain mythological nature.

The result is obvious.

"If it's not a god, what is it?"

Luo Luo was a little confused by He Ao's "not necessarily".

He Ao looked up at her and Lin Chichi and said calmly, "You should know that knowledge itself carries pollution. The more secret knowledge you know, the easier it is to be noticed by high-ranking beings. Are you sure you want to listen?"

"I have no problem!"

Luo Luo nodded heavily, then she looked at Lin Chichi, "But..."

But before she could continue speaking, Lin Chichi quickly said, "Brother Hao Yi, I have already been exposed to these things. I have already been connected with that high-ranking being. It doesn't matter if I know more knowledge.

I can take responsibility for myself."

"Um,"

He Ao stood up slowly, glanced at Luo Luo, and continued,

"Between humans and gods, there exists another kind of mythical creature, 'angels'. Some of them are servants of gods, and some have self-awareness.

"The dividing line between angels and humans is Class A. In ancient times, Class A was also called an angel.

"The process of becoming an angel is very dangerous. It can easily turn into an indescribable and incomprehensible crazy mythical creature, causing unimaginable disasters."

These points are summarized by He Ao from the knowledge he saw in Iliaan's underground library and his own partial understanding.

Luo Luo didn't quite understand what she heard, but she still wrote down these words seriously.

"So this 'Advent Ceremony' belongs to an angel?"

Lin Chichi reacted quickly.

"Um,"

He Ao nodded slightly. He didn't know if there was a higher rank among angels than A, but judging from the dense complexity of the pointing pattern, this advent ceremony most likely belonged to a relatively weak angel.

But no matter how weak it is, it is still at least A level.

He Ao retreated to the wall at the entrance and continued, "Whether it is this kind of advent ceremony or a communication ceremony, all rituals for high-level beings must meet the three elements of the ritual, namely the altar, the sacrifice, and the host.

"The altar is the place where the ritual circle is painted. It is responsible for establishing passages and anchoring coordinates. The sacrifices are responsible for supplying energy or pleasing high-ranking beings. The host is the host of the entire ceremony and is often the initiator of the entire ceremony.

hub.”

"So the blood pool in the carriage just now was the sacrifice? Our place is the altar," Lin Chi Chi quickly summarized what He Ao said, "But... there seems to be no host."

"No, yes," He Ao leaned against the wall, "we are the 'hosts'."

Lin Chichi: "Ah?"

"To be precise, the 'player' who is constantly playing the killing game in the car behind is the 'host' of this ceremony."

He Ao slowly explained, "As the hub of the entire ceremony, the host determines the success or failure of the ceremony. Once the host has self-awareness and gives up the ceremony for some reason, the advent will fail.

"The person who arranged this ceremony may have done it to control risks, or maybe there was no suitable candidate, so he made a clever design.

“Deploy a ‘trap’ that constantly lures people into it, and then use a killing game to lure people into the trap to kill each other.

"This game is actually a special 'ritual'. During such killings, everyone in the game will form a twisted obsession with killing as the main body.

"This obsession leads these killing souls to become the 'host' of this advent ceremony.

"As long as the game continues and the passengers continue to kill endlessly, this obsession will always exist, carrying the soul of the dead in vain, becoming a conceptual host who has no self-reason and only promotes the ceremony.

'.

"And the passengers' corpses and souls after death will become the 'sacrifice' for the supply ceremony, killing two birds with one stone.
