Bai Ye didn't say much about Yu Ye's words, making sure that the jade skeleton had already controlled the 'underworld on the earth', and emphasized again that it was not allowed to go out of the 'underworld on the earth' to erode the yang world.

Then, he set off with the dark night and headed towards the Demon Kingdom of the Dark Qin.

This place is tens of thousands of years away from the Demon Land of the Underworld, and the dark night knows the direction very well, so it is not to mistake the direction.

In fact, when Bai Ye summoned her over earlier, Yu Ye was also wandering around the Stygian Demon Kingdom, wanting to find an opportunity to sneak up on the Stygian Demon Kingdom again.

Since the discovery of the Hades Qin Demon Kingdom and the discovery of the 'Demon Dragon Demon Court' Dao system inherited from it, the attention and energy of the dark night have basically been attracted to the side of the Hades Qin Demon Kingdom.

As long as she is in the underworld, she is basically around the Hades Qin Demon Kingdom, always thinking about and looking for opportunities to attack the Hades Qin Demon Kingdom.

Yu Ye couldn't wait, and Bai Ye didn't want to waste time, so the two of them flew away quickly all the way, and there was no delay halfway.

In less than ten days, the two of them arrived at the underworld where the Demon Kingdom of the Underworld was located, on a plateau.

At this point, the night began to be cautious, and landed directly on the ground with the white night, walking on the ground, instead of flying in the sky.

After fighting with the Styx Qin Demon Kingdom for such a long time, Yu Ye has already been full of experience, and he knows the means and strength of the Stygian Qin Demon Kingdom, and in the place close to the Stygian Qin Demon Kingdom, it is impossible to be too careful and cautious.

White Night followed behind Yu Ye, lurking and stealth all the way, and Yu Ye would sprinkle some black powder from time to time and float around, I don't know if it was erasing the traces or the chaotic atmosphere.

Sneaking around like this, turning east for a while, going around west, and sometimes even sneaking underground to go around underground, Bai Ye gradually became a little unclear about the route and direction.

Finally, when he followed the night and dived out from under a river of blood, the night stopped in front of an ordinary hill on the plateau.

She came to the dirt wall on the side of the ravine, stretched out her hand to measure the up, down, left and right, and after some calculation, she locked on a position, and did not use her mana, but reached out and tapped lightly and heavily on the dirt wall, as if she was activating some mechanism.

In a few clicks, a hole was quietly cracked on the dirt wall, and there were several dry bones lying in the hole, sensing the movement, and immediately got up, a pair of black hole skull eyes, burning with green ghost fire, looking towards the two of the white nights.

After seeing the night, several skeletons stopped moving, and spread out to the ground again, like a pile of dry bones.

Ignoring the skeletons guarding the door, Yu Ye beckoned to the white night, and walked towards the entrance of the cave first.

Bai Ye hurriedly followed, entered the entrance of the cave, and walked all the way towards the depths of the cave.

After not going far, the night stopped again, and instead of continuing to move forward, he made another effort on the wall of the cave, and as a result, a hole appeared in the wall again, and there were also several skeletons guarding the door.

Yu Ye directly entered the new cave entrance, Bai Ye followed, while entering the new cave entrance, he turned his eyes to look at the direction of the old cave entrance extending to the depths, and he didn't know where it led, and it was estimated that it was also some obstacle set up by Yu Ye.

In the subsequent journey, Yu Ye walked halfway several times, but suddenly opened another door on the cave wall and turned forward, like an underground labyrinth, with too many wrong paths and misdirections.

Bai Ye believes that if there is no guide from the dark night, it is absolutely impossible for outsiders to find her lair after they come in.

It's good not to get dizzy and get lost.

When Yu Ye once again opened another portal on the wall of a cave, Bai Ye finally couldn't help it, and sighed lightly: "You are too cautious!"

"In the Nine Demon Realm, if you are not cautious enough, you will die a long time ago!" said Yu Ye without hesitation.

Bai Ye was also speechless, so he could only follow her silently.

Finally, she didn't change direction again, and walked all the way through the cave to an underground hall.

The area of this underground hall is not large, less than ten zhang square, but there are many things inside.

In the hall of less than ten zhang, there were nearly 100 balls of light floating up and down in the air, and there were scenery and figures flickering in each ball of light.

Bai Ye looked at the balls of light curiously, judging the scenes and figures in the balls of light, and speculating on their functions.

Yu Ye pointed to those balls of light, looked at Bai Ye, and said with some pride: "These are my eyeliner! My eyeliner is all over the Stygian Qin Demon Kingdom!"

"Eyeliner?" Bai Ye looked at the nearly 100 balls of light in surprise, and couldn't help but be surprised: "It seems that you have made a lot of efforts over the years." ”

"Of course!" Yu Ye said with some pride: "You know, my current strength is not small compared to the Stygian Qin Demon Kingdom, I can only fight guerrilla attacks with them, constantly looking for opportunities to sneak attack, and retreat if something is wrong!"

"And if you want to fight guerrillas, what is the most important thing? Of course, intelligence information!"

"Without enough eyeline, without enough comprehensive information, how can I choose the most correct and best target every time?

"You really have a talent for guerrilla warfare!" Bai Ye nodded, stepped forward to carefully observe the scenes in these balls of light, and gradually found that they were indeed the scenery on the underworld plateau, as well as some pavilions and black cities, he couldn't help but say, "Can you introduce these eyeliners to me?"

"Of course!" Yu Ye nodded, stretched out her hand towards the nearly a hundred balls of light, and immediately flew out of them, twelve balls of light flew out of them, she opened them one by one, and each ball of light immediately enlarged, and she could clearly see the scene in it.

Bai Ye found that the scenes in these twelve balls of light were different, whether they were hills, or river banks, or hills, or flat land, but what was the same was that there was a black castle in each place, about the same size and style, and each castle had a 'black dragon flag' on it, and there were zombie patrols on the castle.

"These twelve places are the twelve fortresses on the border of the Styx Qin Empire, surrounding and guarding the entire Stygian Qin Demon Country!" "They form a large array, enveloping the entire Stygian Qin border, if we want to go deep into the Stygian Qin Demon Country, the large array formed by these twelve castles cannot be bypassed, we must break one!"

Bai Ye looked at her suspiciously, and said, "There is such a big array covering the border, then how did you enter the Stygian Qin Demon Kingdom to fight guerrillas?"

Hearing Bai Ye's words, Yu Ye showed a hint of embarrassment on his face, and said, "The large array formed by these twelve castles is a newly built new one recently built by the Stygian Qin Demon Kingdom...... I must have been scared of my guerrilla fight, so I had to block the border. ”

"And since they laid down these twelve castles to form a large array, I haven't been able to break through and fight a guerrilla ......"

Bai Ye listened, a little helpless, and said, "It turns out that this is still your fault!"

An embarrassed smile appeared on Yuye's face, and said, "Who knew they couldn't afford to lose so much." ”
