Tian Mo and Xiao Ao infiltrated the treasure room of the Nether Tower through the forbidden spell-level space-time magic, where they saw many precious jewels and artifacts, as well as some spell patterns that people had to be careful about. The treasure room was divided into several floors, and the first floor did not find the artifacts they were looking for, and the two of them could only advance to the second basement floor.

Compared to Xiao Ao, who recorded the spell while walking, Tian Mo didn't have that mind, he didn't dare to be interested in the Yin and Yang spell, and he was not in the mood to record anything, he just hoped to find the artifact quickly, leave here, and go to the next destination.

After coming to the second floor, they found that there were many fewer lights here than on the first floor, and compared to the first floor, there were many places where the lights could not shine, and it was all dark there, and Xiao Ao needed to use magic to illuminate it. For the sake of ease of action, Xiao Ao summoned fire elemental spirits, one following Tian Mo and the other following himself, so that the two of them could act separately.

Under the light of the fire elemental spirits, those dark places can also be seen clearly, and sure enough, the dark places are still full of this kind of spell pattern, if someone is too troublesome to light up here, it is estimated that it will be easy to touch them.

The two of them checked the second basement floor of the treasure room for a while, and found that there was nothing they were looking for here, so they had to go to the next floor to take a look.

They reached the entrance of the lower level, and when they looked down, there was even less light below, and even a light in the center of the treasure room was black.

After Tian Mo and Xiao Ao went down to the third floor of the staircase, they did not continue to move forward, because they found that the layout of this floor was different from the upper two floors, and the patterns on the ground under the light were clearly spell patterns, these spell patterns were relatively high, Xiao Ao did not know what they meant, but he felt that as long as someone entered, there would be a problem.

"We have to be careful. Xiao Ao reminded.

He and Tian Mo began to search in the dark places with the light of the fire elemental, avoiding approaching the area with the spell in the middle.

But nothing was found on this level.

The two of them came together, "How many floors are there?" Xiao Ao asked.

Tian Mo closed his eyes and borrowed the realm of time and space to check here. After a moment, Tian Mo opened his eyes, "There are two more floors below..."

Xiao Ao frowned, "The situation is a bit grim now, now this layer is already a bit special, what will the next two layers look like?"

Tian Mo could only feel the general situation below, what it looked like, he didn't have that ability yet.

When they reached the staircase leading to the fourth floor, the two men stopped again, and there was almost no light.

The two of them took a closer look and found some anomalies, there were many tiny threads here, they were distributed in various places that were not easy for people to find, and if they didn't pay attention, they would come across them, although they didn't know what would happen if they touched them, but they would definitely be discovered outside.

After they illuminated it with the fire elemental, there were more spell patterns here, and some of the spell patterns looked dangerous, probably the kind of spell patterns that would cause damage when touched.

"It looks a bit hard to move here. Xiao Ao looked around carefully, there are thin lines everywhere, and if you don't pay attention to it, you will encounter it, and the thin lines in many places are arranged very tightly, and normal people's bodies can't pass at all.

"There should be some mechanism here to turn off these thin wires. Tian Mo was also looking around carefully.

Xiao Ao let the fire elementals fly into the room on their own, and these fire elements were small enough to easily pass through the gaps of those thin lines.

But there's nothing here that looks like a trap.

"Maybe the trap here is outside, not inside the treasure room, or maybe some special spell is needed here to disarm the trap here. Xiao Ao analyzed.

Of course, Tian Mo also meant this, "We have to quickly find a way to get in." ”

Now the situation has temporarily stopped Xiao Ao and Tian Mo from advancing, and the two of them have nothing to do with these thin lines with mechanisms.

Time was ticking, and five minutes later, there was still nothing good for the two of them.

Outside Dongmu City, Alfred Bruce and the others had already arrived at the hill where they had been stationed a few days earlier. They looked at Dongmu City, there was nothing unusual there, it seemed that Xiao Ao and they had not been discovered.

Lucia also looked anxiously in the direction of Dongmu City, she was still very worried about Xiao Ao.

Nandena was also very nervous, although she was very familiar with Xiao Ao and others, but before this, she had never participated in the actions of Xiao Ao and others. This time, in order to find the heroic relics of Aaron's allies, it was the first time she participated in the mission of Xiao Ao and others.

"They'll be fine. Nandena walked over to Bruce.

"Sister, it's okay, we have to believe Xiao Ao. Bruce reassured. The relationship between their sister and brother is still very good, unlike Alfred and Lucia, although they are brother and sister, but there is almost no communication at all, Lucia has always had a certain prejudice against Alfred in her heart, and the relationship between the two is also like a familiar stranger.

While they were still anxiously waiting, Tian Mo and Xiao Ao were still thinking about how to explore.

"Looks like we're going to have to use magic to figure these things out. Xiao Ao said, and then he raised his hand and began to chant the incantation, which kept changing in the palm of his hand, slowly conjuring into a "summoning beast" in the shape of a beautiful bird.

"What is this?" asked Tianmo.

"It can take our place to look around on the fourth floor. Xiao Ao smiled mysteriously. Then he raised his hand, and the bird flew out, and streaked through the brilliant lights.

What's even more incredible is that this little bird touched those silk threads, and the silk threads did not react, which shows that this magic bird has no physical characteristics. It's like an illusion that doesn't exist in this real world.

"Alright, let's take a break. Xiao Ao drew a box in front of them with his hand, and then, in the box, what the magic bird saw, under the light of the fire elemental, they were like people on the other side of the monitor, they could see every corner of the fourth floor without moving.

In the end, Tian Mo and Xiao Ao simply sat on the stairs and manipulated the magic bird to search for traces of the relics on the fourth floor.

Tian Mo really admires Xiao Ao at this time, Xiao Ao's magic attainments are really too powerful, like this kind of monitoring magic in the eyes of ordinary magicians needs the help of some magic tools, but Xiao Ao can make these out of thin air, which makes Tian Mo convinced, judging from the magic alone, Xiao Ao is indeed much more powerful than Tian Mo.
