At the moon's head, Isenus knocked on Leo's door.

"Put this outfit on. Esenas threw over a black leotard and said, "I'll go out and bring another mask later." ”

Leo took the night coat and asked as he changed it, "Is it just the two of us?"

Isenas nodded: "Ente's skill movement is too big, or is he better at a head-on battle like a tough battle, and his height is not suitable, does he have, seven feet? or eight feet?"

"Taller than me. Leo recalled.

Seeing that Leo was neatly dressed, Isenas took out two more masks from his bosom and said, "Remember to stuff the exposed hair into the mask as well, so that no hair will fall out or something." We went down through the window. “

Esenas pushed open the window and looked around to make sure no one would spot them, then beckoned to Leo.

The two of them rolled over and landed lightly, and slipped out of the courtyard along the shadows of the wall.

Within two steps of walking, Isenus suddenly stopped and patted Leo on the shoulder.

Isennus's sudden movement made Leo look around nervously and ask, "What's wrong?

Esenas looked at Leo who was highly nervous speechlessly, and guessed, "Wouldn't you have done these sneaking things before?"

"This is my first time. Leo said honestly.

Isenus was starting to feel a little pain in his head again.

Between incompetence and inexperience, he prefers to choose teammates with inappropriate abilities. The former is at best underplayed, while the latter often represents danger and accidents.

"Relax, just as we were walking in the back garden, and you see where Lao Mo lived. Isenas tried to make Leo's state more natural, pointing to the sky.

Leo looked in the direction of Isenus's finger, and there seemed to be something strange in the sky.

Leo narrowed his eyes, trying to see better.

"Those are three alchemy birds, the product of biological alchemy. Esenas explained in a low voice.

Leo was taken aback, and with the introduction of Izenus, the little things in the sky were gradually recognized by him, which were three gray-black birds circling around Omoni's dwelling.

"Is this surveillance?"

"Of course, this shows that Lao Mo's rhetoric during the day is very successful, and the pressure on us to sneak in will be much less. “

When Leo heard this, his expression suddenly relaxed a lot, and his nerves were not overly tense.

Esenas also breathed a sigh of relief, fortunately he found Leo's problem before he officially infiltrated, otherwise it would have been a big trouble when Leo was too nervous and made an undeserved move at the critical moment.

Artisan Town is worthy of being a boutique town that only has certain assets to live in, not only the houses are exquisite, but the night patrol is also different, the night security of Artisan Town is patrolled back and forth by several teams of knights, and a large number of alchemical creations are interspersed with a large number of alchemical creations wandering in the dead corners, Leo and Isenas stop and go along the way, hiding and hiding, until late at night to touch the vicinity of the stone tower.

The two of them circled around the bottom of the tower twice, and then returned to the gate of the tower to hide.

Leo scratched his head and said in embarrassment: "This defense is too simple and crude, except for a door, there is no other entrance, not even a window. What are we going to do, knock the two janitors at the door unconscious?"

Esenas immediately rejected the proposal: "Not to mention that the patrol will also pass through the tower, although I don't know what the interval is, but I don't think it will be more than two hours at most." And whether the dive is successful or not, we will leave traces of the dive. “

"What then?" Leo frowned, his arms folded over his chest, and he looked up and down the barrel-like tower.

"That's why I chose you to dive in with me. I remember that your Sanctuary ability is pressure sensing, right?"

"Yes, is this ability of any use here?" Leo still looked at the tower again, trying to find his loopholes.

Isenus pointed to his eyes and said, "Sometimes what you see with your eyes is not necessarily real, and Sanctuary abilities are manifestations that transcend the limits of the human body... You try to feel the danger and abnormality of the tower with the pressure sensitivity. “

Leo nodded, closed his eyes and began to use the pressure sense, and suddenly, the trajectory of the air flow around him was reflected in his heart, and the air flow exhaled by the two guards at the door dissipated not far from the tip of their pen, and there were also two breaths a few hundred meters away. Leo guessed that it might be two dark whistles.

The pressure sensing extends further, touching the façade of the tower. The air was quietly clinging to the walls, except for a few places where the air twisted and swirled abnormally.

Leo opened his eyes and said hesitantly: "There are two secret sentinels a few hundred meters away, here, here, and behind the outer wall, these three places are a little strange, but I don't feel the danger. “

Isenus carefully observed the three places pointed out by Leo, and his eyes were a little sour, but he still couldn't find anything different from these stone bricks.

He had no choice but to rub his eyes, and said helplessly: "One of the great joys of adventure is that you never know what kind of strange skills you have to face, but you can still take risks and succeed... These stone bricks may have used some technology unique to Artisan Town, probably a reconnaissance alarm or something, let's go, let's go in from here. “

Looking at the blank wall that Isenus pointed to, Leo suddenly realized: "Yes, your Sanctuary ability, it turns out that Sanctuary ability can still be used in this kind of place."

Isenus pressed his hand to the wall, and without seeing him make any movement, the stone bricks turned out one after another silently, revealing a hole of one man tall, and Leo immediately followed after Isenus.

As Isenus and Leo entered the cavern, the turned stone bricks returned to their original places one by one, and it was completely unrecognizable that a passage had just been opened here.

Because there was no light source, the tower was completely dark, and even if the two of them had good night vision, they could not see the slightest, so Isenus had to light a fire fold.

"The smoke from the ignition of the fire fold may leave some marks, and the flame will occasionally lick something and leave a trace..."Isenus was reluctant to use such a lighting tool, he was always demanding perfection, so that he could not use what could leave a handle.

Leo was optimistic: "If we act lightly, no one will notice these traces in a short time, and no one will come to us anyway, which is no different from leaving no traces." ”

Although Isenus did not agree with this self-hypnosis, there was no better way, so he shook his head and observed his surroundings.

The slightly cramped room was covered with a finger's height of dust, and in the center of the house there was a wooden staircase that spiraled upward. It seems that this place has indeed been firmly closed for more than 20 years, as the locals say.

Everything here seems to be the same, but the sharp-eyed Isenas has noticed something.

Isenus beckoned Leo to an experimental table, and smoothed out the footprints of the two men.

The lab table was littered with lab instruments, a dozen bottles and jars lying crookedly on the table, and some sticks, tweezers, and the like.

"Is there anything wrong with that? just because they're slumped on the table? isn't that arbitrary?" Leo looked at for a long time, but didn't find anything special.

Isennus didn't pay attention to these, he gently touched the instruments, and asked, "What do you see what these instruments are made of?"

"Glass, wood, stone. ”

"A core lab uses these things for experiments?"

Isenus immediately asked the key point, even if most of the experimental instruments are made of ordinary materials, then there should always be some rare instruments made of precious materials, right?

Leo pondered, trying to argue against the argument: "Maybe they took it themselves?"

Isenas shook his head and said, "These things are all matched, and they should be a set to be valuable." ”

Leo thought for a moment, and after agreeing with the discovery, he began to follow this line of thought: "You mean that people like us have been here before?"

"That's right. Esenus nodded affirmatively. "And these people must have the same ability to erase traces as I do, but their greed still exposes their tracks. ”

"So what did these people find here? They can't have already taken the clue we're looking for, right?" Leo looked a little worried, if the clue was broken here, it wouldn't be easy to find.

"Take it?" Instead of worrying, Isenas said sarcastically, "According to their greedy style, I'm afraid they will be caught before they discover the secret here." ”

"Caught?" Leo was really taken aback, judging from the current situation, except for the difficulty of sneaking in, the rest of the place was very safe.

As he walked up the stairs, Isenas said, "Remember when they explained why they didn't demolish the tower? I didn't believe this argument from the beginning, the bottom tower was already in danger, and even if it wasn't demolished, the upper part shouldn't be used, and if the lower part of the tower collapsed one day, all of them would be buried together, and it would have been wiser to erect another tower elsewhere. ”

"As long as you have the heart, there will always be people who will find the loopholes under this rhetoric and come here to explore quietly. Although the Council of Five has the intention to defend, in order to keep the secret, it can't strengthen the defense here in a big way, so the only method they will use is traps. ”

"Trap?" Leo tensed up again, nervously calculating where to put his feet, and carefully so that his body did not touch any extra parts of the tower.

"Yes, traps. The team of thieves must have triggered some alarm when they were rummaging through things, and they were caught and arrested before they reached too high a level. Isenas glanced at Leo, who was starting to get too nervous again, and immediately advised: "No matter what strange things you encounter, don't make drastic moves, we will discuss and discuss before acting." ”

Isenas shook his head secretly in his heart, although Leo is not weak and has some adventures, but the situation he faces is still too few, and he still needs to hone more.

The two of them walked higher and higher, although they occasionally saw some weapons made of unknown materials, armor, or strange props, but both of them cautiously did not touch them, and just walked up intently.

Cautiously, they came to the seventh floor of the tower.
