Over the next two days, Liang and Isabella drove around the city like regular tourists, stopping to take photos at certain attractions or museums.

But in reality, the two of them used travel as a cover to reconnoiter the area around the historic buildings to see if there were any remnants of supernatural power.

It's a pity that there is no extraordinary reaction at these locations at all, even Notre Dame Cathedral, which claims to have a crown of thorns, is clean in terms of extraordinary power.

"I think this kind of place, if there were anything extraordinary, would have been taken away a long time ago." After coming out of the Louvre, Isabella spoke to Liang En through a soul connection.

"Although it is said that this world cannot be cultivated, there should be some understanding of the use of transcendent items, so everything in this kind of place must have been screened once, and if there really exists transcendent items, they will also be taken away."

"You're right." Liang En, who was back in the car, started the car and continued, "So let's go to the last important spot, if it doesn't already exist, we'll really have to try our luck all over the city."

Soon after the car started, it crossed the Seine towards the 14th arrondissement, and it took them 20 minutes to reach the Place de Danfer-Rochaelau, three kilometers away, because of the traffic jam.

As soon as they parked their cars and entered the plaza from the parking lot, they saw a Belfort lion sculpture entrenched in the traffic at the crossroads. And near the lion statue there are many people lined up in a long line.

These people, like Liang's destination, are the catacombs in the 14th arrondissement of Paris, which is also the largest and most legendary cemetery in the entire city of Paris.

It started as an open-pit quarry outside the city of Paris, but gradually excavated underground until the 15th century, when it was abandoned for various reasons and then forgotten.

Until the 18th century, a huge plague hit Paris, and in a short time the Paris cemetery was full of corpses, and every burial place was excavated several layers, but a large number of corpses and liquids were still abandoned all over the streets.

There was no doubt that this type of burial would only lead to the spread of the epidemic, and in order to solve the public health crisis, the mayor of Paris decided to turn out all the cemeteries in the city and move all the bones to the abandoned quarries underground.

The church undertook the specific work of relocating the cemetery, but the work was enormous because it had to resettle all the dead over the centuries, and it was not officially completed until nearly a hundred years later, in 1810, with a total of 6 million to 7 million remains.

Today, the total length of the catacombs is about 300 kilometers long, but only one kilometer is open to the public, and what Liang En and they have to do now is to enter the underground in the name of visiting, and then feel the transcendent atmosphere up close.

The entrance to the catacombs is housed in a small house on the edge of the park, which is the only legal entrance to the catacombs in the entire Paris area, and the light gradually dims after buying a ticket to enter the room and spiraling down the 83 steps.

As soon as he entered the cemetery area, piles of bones appeared on both sides of the tunnel, and even if Liang En knew that all the guys around him really jumped out and couldn't stop his sword, he still felt a chill hit his heart.

After all, for self-aware beings, there will always be some special feelings and inexplicable sadness when seeing the remains of the same kind, which is the so-called sadness of the dead rabbit and fox.

"Thank goodness it's a world where supernatural powers don't exist." Looking at the rows of remains around her, Isabella said with a sense of joy.

At least in the ancient world, there was absolutely no city that dared to put such a large cemetery underneath, otherwise it would be easy to mingle with the ancestors who raised up from the coffin in three days.

As Liang En and the two of them went deep into the ground along the passage, the surrounding environment became more and more gloomy, and at this moment, Liang En felt that the compass pointer he was carrying began to rotate.

"Huh?" The spinning hands lifted Liang En with a surging spirit, and he didn't expect that he had actually found an aura that matched the transcendent aura that Nicholas Flamel possessed when searching for the last important location.

Determine where the spiritual power gathers is

After the location was located deep in the catacombs, Liang En and the others relaxed and pretended to be tourists who had visited the open part of the catacombs, and then went to the surrounding attractions, which looked no different from ordinary tourists.

It wasn't until 11:30 p.m. that the two men, pretending to be resting, used illusions to slip out of the room and flew for a few minutes along the underground drainage system that stretched throughout Paris to a red brick wall.

"This should be it." After turning into a human form from the light, Isabella said as she looked at the blackened red brick wall in front of her. "Based on my previous investigation, this should be the closest entrance to the target location."

The underground drainage system in Paris is also a very old one. Dating back to 1370, the first sewer system was built beneath the now famous Avenue de Montmartre.

Since then, the underground drainage system of Paris has been expanded throughout the city, especially in the 20th century, from 1914 to 1977, when more than 1,000 kilometers of sewers were built throughout the city.

In this case, the underground of Paris naturally has a huge network of underground networks like spider webs, and the underground network of different systems is prone to certain contact points.

The wall they found now is one of the many partitions separating the underground drainage network from the underground cemetery of Paris, and the brick wall is three meters thick to prevent the two from being connected.

But this obviously couldn't stop Liang En, I saw him walk to the brick wall and lightly tap his fingers twice, and the next moment the whole wall trembled, and then those bricks quickly avoided the place where Liang En had just knocked with his hands.

It seemed that in the next second, a fist-sized hole appeared in the wall, and then the hole grew larger and larger, and finally turned into a red brick arch.

"Please—" Liang made a gesture of please.

Soon, the two of them passed through the arch that formed in the wall. When she reached the other side of the arch, Isabella turned her head to find that the arch had become a solid wall again.

"It's a pity that I can't learn alchemy, and if I were to change it, I might just make a hole in the wall." Isabella spitted, and then walked forward after Liang En.

Unlike the open catacombs they had visited before, the tombs in this place had apparently never been disturbed.

There was a thick pile of dust everywhere, and there were even quite a few human remains on the ground.

In order to avoid disturbing the dead, in many places Liang En and they had to fly in light, and even had to fly out of the cracks of some bones in order to pass through some tunnels.

Because the underground tunnel is three-dimensional, it took them more than an hour to reach the target they had largely locked on, even if they knew the road.

"This should be it."

Looking at the pile of human remains in front of him, Liang En grabbed a handful of dust from the side and gave him spiritual power, and then gently blew towards the gray bones in front of him.

In the next moment, a little visible light emerged from the large pile of bones in front of him.
