Catherine didn't pull the door open at once, but carefully opened a gap and peeked inside, hoping to see Nelson and his captors, but it was empty.

On the contrary, Leo didn't seem to be worried about startling the snake, and without waiting for Catherine to react, he directly opened the door very rudely, kicked the wooden wedge on the ground against the door, stepped in, and said: "No need to look for them, they are no longer here! ”

Leo walked straight to the closest tomb in the entire chamber to the inside, which was different from the other tombs in the chamber in that it was a coffin tomb that had preserved the whole body.

Since several large-scale plagues broke out in the three continents of the Velen world, the funeral habits of the Velen continent have changed, except for those wealthy merchants and nobles, the vast majority of people will choose cremation.

In a place like Cage City, after the dead are burned to ashes, the ashes are put into the ashes and sent to a niche in the large burial chamber, adjacent to the other deceased, which is the most suitable burial method for a slum like Cage City. And the way of burial in a coffin like the one Leo is facing now is a bit abrupt here.

"This is the tomb of St. Birmingham, who was the chief architect of the sanctuary and who was posthumously canonized by Martin, who was then the Patriarch, and who has been included in the Holy See's register of saints. When Catherine saw the name on the tombstone, she immediately made a religious prayer gesture and explained to Leo: "He also built the Temple of Eternal Sleep, and he was the first person to be buried here." ”

"Birmingham, it sounds like an English name. Leo said casually.

Catherine said, "He is the man of your kingdom of England." ”

After hearing this, Leo didn't say anything, but squatted down and groped under the sarcophagus, and then heard the sound of pulling the mechanism, and then the coffin slowly moved away to reveal a downward staircase, and Catherine showed a surprised look when she saw this scene.

"Wait!" Catherine stopped Leo as he was about to lead the two of them down, then looked at him with a straight face and said, "You'd better explain it first, and then we can decide what to do next?"

Leo asked rhetorically, "Explain what?"

Catherine said solemnly, "Why do you know so much about these mechanisms, why do you think Nelson will be brought here, and where does this secret passage lead?"

"I'll answer your questions one by one!" Leo saw Catherine become serious, and felt the need to explain, so he said, "I said just now that everyone's smell is very unique, for example, your perfume with gooseberry and clove is very unique, and it should be your own blend. ”

Catherine looked surprised when she heard this, and it was clear that no one knew the secret.

Leo continued: "Perfume alone is not enough to make your scent unique, you have some herbs on you, some potions, and these scents are mixed together to make your scent unique. ”

Catherine guessed, "Can you smell the scents?"

Leo didn't admit it, nor did he deny it, just smiled, then pointed to the revealed secret passage, and said: "As long as you track the smell to the place, it is easy to judge whether there are secret doors and secret passages around, because it is impossible for someone to disappear out of thin air, and it is not a person." It's much easier to confirm that you have a secret door and a secret passage, and then look for the mechanism to open. ”

Catherine was stunned for a moment, and finally couldn't help but say to Leo, "Were you a thief before?"

Leo didn't take the words, continued to point to the secret passage, and said, "As for where this secret passage leads, it should be easy to guess, and you should be able to guess too." ”

"Catacombs. Catherine quickly thought of the answer.

"Yes, it's the catacombs!" Leo nodded affirmatively, he would know where the secret passage leads is not speculation as he said, but the spiritual web has already figured out what is going on below. Then he said, "Don't you think it's strange? Mr. Martin wanted to target the doctor for no reason, and the ultimate goal was the catacombs, and now another group of people joined in, and when they caught the doctor, they also took him to the catacombs. What's so special about this catacomb? And what's so special about the doctor?"

Catherine was in deep thought because of Leo's deliberate guidance, but she soon recovered, and it was evident from her thoughtful expression that she had thought of something. It's just that she didn't intend to say it, but urged: "Let's find Nelson first and then talk about the rest!"

Seeing that Catherine was reluctant to speak, Leo did not ask, he nodded in agreement with the offer to find Nelson first, and then he cut down several wall lamps filled with lamp oil from the tomb with a tomahawk from his waist.

Leo's destruction of the sconces made Catherine frown and tried to stop it, but in the end she didn't say anything.

At this time, Leo lit the wall lamp and gave it to Catherine and Jason respectively for tunnel lighting, and put the rest in the backpack for backup.

Later, in order to avoid getting in the way of the wide burqa, Leo took off the burqa again, but did not throw it away, and also put it in his backpack along with the burqa taken off by the other two, so that it could be used as a fire starter if needed.

Finally, he checked the reload of the king and queen, and asked Jason to fill the crossbow he had received from Valjean with arrows, but not the arrows with the special effect on them, but ordinary arrows.

Leo's cautious approach made Catherine feel very nervous, because she had prepared to treat the patient beforehand, and she had never expected such a thing to happen, and even if an accident happened, she felt that she would not be harmed in the parish, so she did not carry any weapons at all, and the only thing that could be regarded as a sharp weapon was a syringe with a needle soaked in an alcohol box sterilized.

"You take this tomahawk first, and hide behind me or Jason when something happens. Perhaps sensing Catherine's predicament, Leo took a tomahawk from his waist and handed it to Catherine, prompting.

Catherine, who was obviously not an ordinary woman, took the tomahawk and swung it twice, nodding at Leo to indicate that she could use it.

After more than seven minutes of preparation, Leo, who had checked everything, grabbed the wall lamp, stood up, walked into the tunnel, walked briskly down the sloping stairs, and after walking some distance, stretched out his right hand and pressed it on a stone brick carved with an inconspicuous pattern on the wall.

Catherine, who was at the back of the tunnel, closed silently behind her, leaving only a faint oil lamp in the hallway.

"Let's go! We still have to catch up with them, we need to speed up. Leo didn't wait for Catherine to think nonsense, then he urged, and then quickened his pace and led the way.

Perhaps because of the fact that she had been walking in the darkness of Cage City for many years, Catherine's adaptability to the darkness was still higher than Jason's, and she soon adapted to the rhythm of Leo's footsteps.

Leo was also surprised by Catherine's ability to adapt, but it wasn't a good thing for him, as he was going to use Catherine as an excuse to slow down.

The grinding process and the idea of slowing down now were all because Leo wanted to know what the people they were chasing now had to do with Nelson, and what were they here for, so well-equipped?

At the moment when the secret passage was opened just now, Leo's spiritual network had already detected the location of those people who entered the secret passage first and Nelson, because the secret passage extended downward in a spiral, although some of it would be beyond the coverage of his spiritual network, but soon the secret passage would turn around, and those people would also reappear in his spiritual network along the secret passage.

And just like Leo's previous information from the scent particles, Nelson was indeed not kidnapped, and from the fact that Nelson was guarded by those people in the middle, it is clear that Nelson was there to be protected.

What's even more interesting is that Nelson is not the only one who is protected, there are two other people, and these two people seem to be very familiar with Nelson, and they will also have some very intimate actions when they are in a hurry, such as patting their shoulders, etc., and Nelson has no signs of resistance.

If Leo immediately led people to chase down when he sensed Nelson and the others, I believe that in a few minutes at most, they would be able to catch up with the people who were not well adapted to the darkness, but in this way, I am afraid it would be difficult to know the purpose of this group.

Therefore, Leo deliberately delayed for a while, allowing Nelson to walk far enough away before leading people to chase down.

However, he obviously underestimated Catherine's ability to move in the dark environment, and at the current speed, if the other party did not get out of this secret passage, they would soon meet.

Fortunately, under the perception of the spirit network, about one hundred and sixty meters down, the secret passage had already reached the exit, and Nelson and the others were only half a circle away from the exit.

Leo continued to move downward at his current pace, and deliberately did not warn of some of the broken steps, causing both Catherine and Jason to make some noises due to the sudden stride under their feet.

Sure enough, as he expected, after the sound came out, those people in the secret passage also heard it, and the speed of travel immediately accelerated a lot, and soon rushed to the exit of the secret passage and walked out.

When Leo and the others reached the exit of the secret passage, the group was nowhere to be seen.

After reaching the end of the secret passage, Leo deliberately groped around the stone wall in front of him for a while, before opening the closed stone door as if he had just found a mechanism, and then walked out first.

I saw that the location of the secret passage exit happened to be in a basement, the stone door just covered the exit, open the stone door and directly enter this basement, you can see the basement exit more than a dozen steps forward, the steps of the exit go up, and you will soon be able to walk out.

"Here, where is this?" Catherine, who walked out of the basement, looked at the unfamiliar surroundings around her, and couldn't help but be stunned.

Although it is underground, the stone walls here and the rocks at the top are covered with a fluorescent plant.

Although the light emitted by this plant is not very strong, it can also play a certain role in illuminating when it is gathered together, and if nothing else, it can at least let people see the general situation of this underground space.

The ruins of a huge city, this is the first impression anyone can get when they see their surroundings.

In addition, the whole city is carved out of the rocks of the earth, which can be judged from the fact that there are no gaps in the contact points of all the building components, such as the beams and pillars of the houses, the foundations and even the roofs, etc., which are enough to judge that these individual stone houses are hewn out of a single piece of rock.

Finally, you can vaguely see more houses on the stone wall in the distance, and it is clear that they are stone kilns carved out of the stone wall, and judging by the number of houses, there were many people living here at that time.

"This is supposed to be the catacombs. Just when the two of them were still shocked by what they saw in front of them, Leo already knew the situation of the underground city, and without too much emotion and excitement, he said in a calm tone.

"No way! I know what the catacombs look like! It can't be the catacombs here!" Catherine shook her head, denying Leo's claims.

Leo said, "Remember how many meters the secret passage went down and recall the location of the catacombs. ”

Catherine thought for a moment, as if she had thought of something, and suddenly looked up at the rock above, and said, "You mean that we are under the catacombs. ”

"I don't know. Leo replied vaguely.

In fact, Leo knew very well that his current location was at the very bottom of the catacombs.

If you follow the normal route from the Sacricade, you will first enter the catacombs, and then through the passages excavated from the catacombs into the residential area of another underground city, and then through the passages opened up in that underground settlement.

Because of the vertical downward direction of the secret passage, people who walk through the secret passage pass through the catacombs and another underground settlement, and directly enter the underground city area.

This was a good thing for anyone who didn't want to disturb the church of Aconaya, and in Leo's perception, there were heavily armed church guards at both ends of the passage from the catacombs to the next dungeon.

If he didn't have this secret passage, he would have to think about how to deal with these people, which saved him a lot of trouble and avoided disagreements with Catherine, who had a special affection for the church.

At this moment, Catherine suddenly seemed to see something, and quickly slipped through a rubble ruin, and came to the center of the dungeon.

This is a central square, and there should have been a huge sculpture on the square, but it has been reduced to a puddle of rubble, but the base of the sculpture is barely preserved, and by the light of the fluorescent plants clinging to the rock face, even those with a slightly better eyesight can barely make out the large text and some strange symbols on the base in the distance.

At this moment, Catherine squatted on the ground, looking at the embossed words and symbols in front of her with a look of surprise, excitement and excitement, and muttered to herself: "Is it true? ”
