The entrance to the cave on the grassland once again ushered in two uninvited guests, who were Xu Rui and Xiaohu.

The battle on the grassland has ended, and the work of re-establishing a new order is also being carried out in an orderly manner, which is just the right time for Lin Shaodong, the new political envoy of Anxibu, to familiarize himself with the work as soon as possible and establish his prestige.

Xu Rui simply threw all the big and small things to him, and he and Xiao Hu secretly set off to go to the fairy world appointment that was made three years ago.

This time, for some reason, Xu Rui didn't take the shadow maid and Yao Li, so he only set off alone with Xiaohu, and only said that Lord Jingluo went deep into the grassland to investigate the terrain.

"I didn't expect the entrance of the fairy world to be so close to the Khan Court."

Xu Rui looked at the hole with a diameter of about two meters, and the darkness stretched out to nowhere and said playfully.

Xiao Hu nodded: "Yes, I didn't expect that the entrance of the Immortal Realm Road would be two hundred miles northwest of the Khan Court, and it would be so conspicuous. ”

Xu Rui looked around, found a few not-so-obvious ruts on the ground, frowned, and said: "The snow melts, winter goes to spring, after a winter baptism, there are still ruts left on the ground, it can be seen that there are a lot of people who came here at the beginning." ”

Xiao Hu said: "This time, the door is fully prepared, almost using the power of the nest, and the elites in the door are all here, and the scale is naturally not small." ”

"That's weird, if you're so determined, why don't you leave a few people at the door to guard it? Aren't you afraid that some people also want to break through the road to immortality? ”

Xu Rui pointed to the empty hole and asked puzzledly.

Xiao Hu laughed when he heard this: "My Hou Ye, do you know the secrets of the fairy world?" ”

As he spoke, a hint of pride flashed on his face and he said: "I dare to guarantee that the only one in the world who knows this road is my Guigu, not to mention that with the danger of this road, even if someone else wants to go, it will never be possible, so why bother to leave someone to guard it?" ”

Xu Rui felt that there was some truth in it, and said worriedly: "Since this place is so dangerous, can the two of us walk in?" ”

Xiao Hu smiled: "Don't worry, Master Hou, the master came in advance this time to open the way for us, we just need to go inside, the master must have cleared all the obstacles for us, and are waiting for us at the place where the door opens." ”

"So I don't have to bother with it?"

Xu Rui asked with a smile.

Xiao Hu nodded: "No, all the preparations will be done for you in advance, you just need to use the power of the bloodline to open the door to the immortals, and then whether you enter the fairy world or stay in the human world depends on your own choice!" ”

"Oh, so what are you waiting for? Ben Hou can't wait to see what the fairy world is like! ”

Xu Rui laughed, and took the first step towards the entrance of the cave.

Xiao Hu was overjoyed in his heart, and hurriedly followed his footsteps, but Xu Rui didn't see that the moment he entered the cave, Xiao Hu glanced at an inconspicuous code, and a cold smile flashed on his face.

After entering the cave, the light quickly disappeared, and when Xu Rui was hesitating to light a torch, he found that there was a faint light in the cave, and the light source came from nowhere, just enough to make people see the way forward.

Because the time was too tight, Xiao Hu kept urging in front, and Xu Rui didn't have time to figure out the principle of luminescence, so he hurriedly followed him.

The scale of the cave was still beyond Xu Rui's expectations, and the two of them walked in the darkness for two days before they could see the bottom, but the soft soil around the cave suddenly turned into a heavy concrete structure.

Xu Rui gently stroked the shocking scratches left on the cave wall, as well as the faint smell of blood wafting in the air, squinted his eyes and said, "It seems that I experienced a bloody battle not long ago, what is there in here?" ”

Xiao Hu thought for a while and said: "According to the records of this ancient book, there are many immortal guards on the path to immortality, preventing mortals from crossing this passage, their strength is incredible, and they can't even tell what kind of demon it is.

But you don't have to worry, the master should have cut off all the immortal guards along the way in advance, didn't we encounter any enemies after walking for a few days? ”

Xu Rui shook his head: "I'm not worried about any enemies, it's a big deal that I can't escape the same way, but how long will this cave go?" We only have enough dry food for today, but this passage shows no sign of coming to an end, and I don't want to starve to death here. ”

"So you're worried about this."

Xiao Hu smiled and said, "Don't worry, Shizun has already thought about it for us, so you just have to go." ”

After saying that, Xiaohu continued to walk along the cave, as if there was really no need to worry about everything.

Xu Rui didn't ask much, since the Guigu Gate paid such a big price to invite him, it means that the so-called Gate of Ascending Immortals must be opened by him, at least he should not be in any danger before opening the door.

It's just that the moment he saw the concrete structure, Xu Rui could already determine that this place was not a road to immortality at all, but a relic of an ancient civilization.

I just don't know what the difference between the ruins here is different from the ruins in the Gobi of the Eight Hundred Miles of Hanhai, and what is the connection with the underground vault in the Khan's Court and the caretaker represented by Yin Ji?

Xu Rui thought about possible explanations in his heart, and unconsciously remembered the formula that Helen left him, the formula was naturally not solved, but through the process of cracking the formula, he seemed to have found some way.

The so-called essence of the world in Helen's mouth seems to be a truth hidden in the fog, which can unravel the original meaning of the existence of this world, and the reason why so many time-travelers appeared.

He had a hunch that there might be a huge secret hidden in this cave that could solve all the mysteries, quietly waiting for him to discover.

The two walked deep for a long time, and Xiao Hu really found the food left by the troops in front of him in a hidden corner.

It turned out that the reason why Xiao Hu was not worried about running out of dry food was because he had long known that the Guigu Gate would be left at intervals for the two of them to replenish.

It's just that when Xiao Hu found the provisions, Xu Rui noticed that a special set of codes appeared nearby, which seemed to be self-contained and different from other codes in this world.

But the moment he saw this code, Xu Rui thought of the secret chess code, which seemed to be somewhat similar to the code of the Guigu Gate, but the core of the code was completely different.

After discovering this detail, Xu Rui's heart moved slightly, and he was concerned about the secret signal left nearby.

The two continued to walk inside for another day, and finally arrived at the place where the Turbid Heart confronted the Ghost Valley elite that day.

Xu Rui carefully observed the nearby environment and found that this was actually a core control room, for Xu Rui's cognition, the equipment inside was very advanced, but it seemed to have worn out over too long and became a little old.

Another thing that made Xu Rui puzzled was that the operating equipment and systems here were very similar to those he used in the other world, but they were different from common human creations, could it be that the civilization that established these ruins in the first place was involved with the humans of the other world?

The more Xu Rui thought about it, the more strange it became, and he gradually became obsessed with everything here, not noticing that Xiao Hu's eyes had become more and more gloomy when he looked at him.
