There is a circular open space around the stone tower, and the outermost stone fence is enclosed, as if forming a forbidden land.

Song Rui and Zebra stood outside the stone fence, where they could clearly feel the oppressive aura, which made people palpitate, and the inconspicuous gray stone tower, like an ancient giant beast, stared at the two of them coldly, making people's hair stand on end unconsciously.

Song Rui swallowed his saliva, "If that tower is not in danger, I will eat Xiang live on the spot!" ”

"......" Zebra rolled his eyes rarely, too lazy to pay attention to the goods.

"By the way, Zebra, I've always wanted to ask a question." Song Rui scratched his forehead, "Is there a hierarchy of this creature like Nitro?" ”

"Strength is paramount...... Probably. Zebra led first towards the tower.

"Probably?"

"Yes."

Zebra was the first to step over the stone fence, followed by Song Rui.

The moment the two stepped over the stone railing, they suddenly heard an angry roar, Song Rui and Zebra paused, followed the sound, but saw that outside the side guardrail of the stone tower, there was a Nitro, judging from the appearance characteristics, it was the one they met at the east gate just now.

The expression of that Nitro was extremely angry, and there seemed to be a layer of blood in the bright yellow pupils, of course, it could not be ruled out that it was due to the influence of the jade skeleton's aura...... At this moment it opened its mouth wide and made a sharp cry in its throat, like that of a bird, but it was thicker than the sound of a bird, and it had a strong penetrating effect, and the sound was rolling and piercing the eardrums.

When Nitro's mouth was opened, the inside of the upper and lower beaks was full of teeth, and it looked terrifying. This creature seems to have been born to eat, with an innate greed for food and a powerful appetite, and all the organs in the body, except for the needs of battle, are all in the service of eating.

In the food pyramid, only a few drops of water were dropped into the coffins of the two Nitro that had been sealed for thousands of years, and they were resurrected from the state of dried corpses, and the body function recovered nearly half in an instant after drinking sweet and smooth Coke, if there is enough food, this creature can recover from the near-death state in a very short time, and it can be said that it is the most terrifying creature found in the food world at present, and it is also the most tenacious creature with the most vitality, there is no one.

At this time, the Nitro was extremely angry, but it was standing on the periphery of the stone fence, without the slightest intention of stepping into the area inside the stone fence, which made Song Rui feel very strange, this Nitro, as if he was afraid? Like a warning to them?

Zebra was also very curious about the Nitro's performance, he had never seen this kind of look or creature in the food pyramid...... There is a saying, two meters six tall, but with a momentum of 100 meters, giving people the feeling that they are never afraid of creatures, but at this time they are facing a tower, showing a jealous look?

Song Rui also saw that this Nitro must not have dared to enter the inside of the stone fence, and he was energetic at that time! I was about to tease the creature, but I was slapped on the back of the head by Zebra, so I had to give up.

Song Rui smiled sheepishly at Nitro, and walked quickly into the stone tower, his expression was like saying: I won't come out, how about it? You're going to hit me, stupid!

The aura that overflowed all around made the corners of Zebra's eyes jump, and he deeply suspected that this skeleton shelf had a hole in his brain!

This stone tower has only one entrance, and it is not like ordinary stone towers with windows on each floor, so Song Rui rummaged through his backpack and found a flashlight.

The space in the tower is not large, and there is no very complicated arrangement, entering the first floor, there is only a small platform half a person high, the platform is golden yellow, the surface is a little rough, and the light that comes in from nowhere just shines on the platform, and the platform is covered with a layer of gold dust.

With such an obvious plot trigger point, Song Rui naturally wondered if there was a trap, and he glanced at Zebra.

Zebra nodded, his echo map kept open, although the tower had an underground part, but there was no hidden passage, he took the lead towards the platform.

The platform is not large, about a meter square, in the shape of an oblique trapezoid, and is stretched with a piece of parchment...... It should be parchment, the paper is slightly thicker, the structure is tight, the color is yellowish, there are some fine textures on it, the texture is not obvious, it may have undergone special treatment, the whole paper looks soft and smooth.

But none of this is important, the important thing is that the map on this parchment, which is smaller than the platform, is a map of this dungeon, and it is marked in detail, but the problem arises again...... That kind of text is still in Babel, and Song Rui can't read it, at least for the time being!

"How important it is to master a foreign language!" Song Rui took a detailed picture of the parchment, and in order to prevent problems, he also made two records.

There was no FLAG around the platform that could be triggered, and after recording the map, Song Rui followed Zebra to the second floor.

The second floor of the stone tower is still the same layout, and this time the map is the internal map of the stone tower.

I don't know who designed this stone tower, what's the point of putting two maps here, the brain circuit is clear.

The third floor has no map, and there are some simple arrangements, which look like living quarters, with a table, a bed, and a stool. There are still no windows, but the third floor is very bright, and the top of the wall and the surrounding area are inlaid with bright beads, and the pearl is arranged in a staggered manner, which makes people feel like they are in the sea of stars when they step on the third floor.

Although it looks like a living place, there is still nothing of value to be found on the third floor, the whole floor is simple and clean, and there is not even a trace of hair smell, so it is completely impossible to guess the species of creatures that live here. But the palpitating feeling is becoming more and more obvious.

Song Rui and the two searched for it, and went directly to the fourth floor.

"......Whew" Song Rui took a deep breath, the feeling of palpitations became more and more obvious, although Song Rui had no skin, but the sense of crisis was like holding a sharp knife on his neck, and the cool and thin blade was against the skin, arousing a layer of fine goosebumps, and the chill penetrated the bottom of his heart.

Zebra's expression was also very solemn, the two of them were highly tense all the way, although they hadn't found anything so far, but this was more stressful, he realized this problem himself, and began to consciously adjust.

Song Rui's pressure didn't just come from the feeling of palpitations, some fragments began to flash in his mind, and he heard a voice that kept shouting the little bones...... Familiar and unfamiliar, his memory is a little confused, something is sprouting in the depths of the memory layer, arching the memory one by one, but it can't break through the ground.

Song Rui tried his best to stay calm, he came in to search for answers, whether it was a memory or a sense of crisis with palpitations, he had a premonition when he came, and it was a good thing that there was movement, and it was not in vain that he risked his own risk to run this trip.
