I have the earth as a plug-in

As you get closer, you can see that there is an inverted transparent cover on the building at the bottom of the lake, which isolates the lake from the outside.

Everyone was still worried about how to find the entrance to it, but when they touched the transparent film, they were dizzy for a while, and the teleportation happened again.

"Aww."

Shen Xu realized that he was alone again. At this time, the little monster woke up, which made him very happy. He touched its small head: "Xiao Jin, you finally woke up. We are now at the bottom of the lake. This should be the building at the bottom of the lake. In the group, we got separated from the others. Let's go and see what's here."

The little monster seemed to be a little depressed, because it actually fell asleep all the way, and only woke up now. It didn't know what happened in the middle, and then quickly cheered up again. It was still very useful, and now Shen Xu was left alone It's a beast, it wants to protect Shen Xu.

Seeing that the little monster cheered up again, Shen Xu also smiled, and then walked inside the building with it.

Looking up, you can see the protective cover like a film, and above it is the lake. The inside of the protective cover is different from the underground world. It is very bright here, as if there is sunlight shining down, and the air is not humid at all, and there is no water on the ground. How much dust has accumulated, if Shen Xu, who has not been exposed to practice and has been receiving modern education on the earth, would not be able to believe that everything in front of him is real.

The stone laid on the ground is excellent, and the building materials of those houses are also very good. It seems that they can directly build first- and second-rank spiritual soldiers. There is a sense of simplicity everywhere. Shen Xu has reason to believe that the buildings here have existed for a long time. It's been a long time, and I don't know when it was handed down.

He walked in the middle, with rows of houses on both sides. He tried to find useful clues in these buildings, but most of the houses were empty. When he entered another empty house, he found a The bookshelf, and there are a few books on the bookshelf, which made him extremely happy.

But when he turned the pages of the book, he could only stare wide-eyed. The characters on it knew him, but he didn't know them, but he seemed to have seen these ancient characters in his grandfather's place. What's the connection between them?

Shen Xu thought for a while, and put these books into the ring, maybe he could take them back and let his grandfather see if he could decipher them, and see what was recorded on them.

In addition to these books, I later found a shell-shaped shield that fell on the ground in a room, with cracked lines on it, and it looked like it had been smashed open with great force.

Shen Xu didn't know if the shield was still useful, so he punched the shield with all his strength, his fingers felt a little painful, but the cracked pattern on the shield didn't change at all.

Seeing this, the little monster was not convinced, and jumped over to catch the shield with its claws. The claws were very sharp. Shen Xu had seen a monster's brain smashed by scratching, but after scratching, the shield remained unchanged. .

The little monster was even more unconvinced, and wanted to continue to challenge the shield, Shen Xu quickly stopped it: "Don't, this shield might be a treasure, we have to keep it, maybe it will come in handy sometime."

That being said, Shen Xu has already determined that it is a treasure in his heart, because the sharp claws of the little monster did not even leave a paw print on the shield. Shen Xu dares to say that this shield will be at least a fourth-rank and fifth-rank He didn't want to use his own sword to test it at all, in case the sword he just got would be damaged.

The little monster jumped back on Shen Xu's shoulder, gritted its teeth, and looked quite shocked.

Shen Xu happily held the shield in his hand, he must have a defensive spirit weapon, if he wants to change to a spirit weapon of the same level, thousands of contribution points are absolutely indispensable.

"Come on, let's go find the others."

Although everyone dispersed, Shen Xu felt that no matter how big the underground complex was, it was limited, and everyone would meet sooner or later.

So he walked all the way along the road in the building, feeling that this road would lead to the center of the entire building complex.

Behind the rows of houses, there is a large open space. Shen Xu reckoned that this place should have been a garden, but now there is only soil left here, not even a grass root. He looked up thoughtfully. The thin film shield, the aura in the shield is very scarce, is the aura used to support the energy shield above?

Because even in the soil of this garden, the aura is very scarce. Even if a piece of spiritual grass and spirit flowers grew, it probably withered and turned into soil due to the scarcity of aura.

"Huh? Shen Xu!"

"Shen Nuo! Just you?"

"Yes, it's just me. I'm still wondering where you all fell. This time, I met you first. Let's go, let's find someone else." Shen Nuo said happily.

"You've been spinning around here? Did you find anything?"

"Let's pull it down, it's all empty, there's nothing there, and seeing a large open space outside, I wondered if there would be a Lingzhi Garden, but in the end, hehe, you saw it too."

Hearing Shen Nuo's complaint, Shen Xu couldn't help laughing, he raised the half-damaged shield in his hand: "Then I'm not bad, at least I have this harvest."

"Haha, a shield that is about to break, yes, Shen Xu." Shen Nuo looked at the shield and laughed.

Shen Xu let him laugh, and did not explain to him the peculiarity of this shield. If there is a chance to play its role, Shen Nuo will naturally be able to see it, so let him be envious.

Even the little monster despised Shen Nuo, and even its claws couldn't scratch the shield. The little monster was not convinced, but in its heart

In fact, I still admit that this broken shield has some effect.

Going forward, they met more and more people, and finally they arrived at a square, and the rest of the people had already gathered in the square, Song Qian and Dong Wei were also there, and the four of them met again.

"How did you gain anything?"

"Hehe, there is nothing. Now we are going to see the last palace. Brother He said that we will wait for everyone to come together before going in." Song Qian pointed to the tallest building on the square, which is very magnificent. They were teleported to this palace The rear of Shen Xu and the others happened to be in two directions, so they didn't meet until now.

Everyone gathered, except for Shen Xu who held a broken shield in his hand, everyone else's hands were empty, everyone looked at Shen Xu and laughed, after the incident that Shen Xu was a porter in the fog before, now everyone looks at Shen Xu. Very kind.

Shen Xu was ashamed. Of course, he also felt that some people might not tell what they got. For example, he still got a few books, but he didn't release them.

"All the people are here, let's enter this last palace."

"Listen to Brother He."

"Walk."

He Qiong led the team at the front, the other fifth-rank members consciously held up behind, and Shen Xu and the others walked in the middle.

The palace has a thick gate. He Qiong put his hands on it and exerted force. The thick gate slowly opened inward. This was the first sound from the underground complex. Shen Xu looked up unintentionally and found the protective shield above it. There is a slight tremor.

His actions attracted the attention of others, and they looked up together.

"It seems that the core of this shield is in this palace."

Light suddenly appeared in the originally dark palace, and everyone followed He Qiong into the threshold one by one, and found that the space in the palace was larger than they thought. , I do not know what people use.

"Look, there's an altar in the middle."

"Be careful."

He Qiong didn't make a sound, held a sword in one hand, and although his pace didn't slow down, the vigilance of his whole body was raised to the highest level, and he could switch to a fighting state at any time

The palace was filled with a solemn atmosphere, except for someone talking when they first entered, everyone was silent afterwards.

Soon, everyone saw the scene on the altar. There was a black bead on it, the size of a baby's fist, and it was covered by a transparent cover. The closer they got to the black bead, the more pressure they felt. He approached them face to face, and his body kept crushing them like a heavy weight.

This feeling is not much better than the multiple gravity of the gravity peak.

Someone said in surprise: "Senior brother He, what is this thing? We feel that it is all caused by this black bead?"

"Actually, this is coercion. Could it be that this black bead belonged to some kind of powerful creature before, and the coercion of his life still remains after the death of the creature?"

He Qiong still insisted on moving forward, but his steps became smaller and smaller. His face, which was always calm, also began to flush because he was moving forward under pressure, and sweat oozes from his forehead.

He finally opened his mouth: "It is indeed likely to be something left behind by a powerful creature after death. You should remember the name of this secret realm, right?"

Everyone was shocked: "Could it be Xuanwu? But isn't it called Xuanwu Secret Realm because of that Xuanwu puppet?"

Divine Beast Xuanwu? !Everyone couldn't believe it. All kinds of mythical beasts had already become legends in the Tianyuan Continent. Could it be that there really was a basalt mythical beast in Tianxia Academy?

If it was really a basalt beast, wouldn't the black bead in front of him be... The eyes of everyone looking at the black bead also became fiery.

Shen Xu looked at the black bead with very complicated eyes. Although the black bead was a little bigger, he felt that the black bead was somehow related to the mysterious bead in his body, and he was born outside the lake before. The subtle induction should come from this black bead.

Seeing how hard everyone was persevering, Shen Xu wanted to hold his breath and turn his face red, pretending to be working hard like everyone else, but he didn't actually feel much pressure, which made him more certain that this body in his body This bead is related to the black bead.

"Then this black bead is the inner alchemy left by the Xuanwu beast?" Someone finally called out.

"But we can't even get close, how can we get the inner alchemy of this Xuanwu beast?"

"Senior Brother He can do it, Senior Brother He hasn't stopped yet."

"Yes, Brother He, come on, let's cheer for Brother He."

Some people sat down on the ground and gasped for breath after speaking, their faces flushed like a monkey's butt.

With this beginning, there were thumping sounds in the palace one after another, Shen Xu followed Shen Nuo and the others also fell to the ground, making a very strenuous appearance.
