The depth of the walls was somewhat beyond Han Kun's expectations. Unexpectedly, Dono has been digging five kilometers directly below to dig the head, it is not easy to repair the building to such a depth, not to mention that the area of this wall is so large, Dono who set off directly below is still the first to reach the end, and Dono who is heading in other directions is even digging along the wall.

After reaching the finish line, Han Kun immediately retracted Dono from other directions, and then as if he had climbed over an obstacle, after bypassing this wall, Han Kun began to dig upwards again, only this time he chose to keep a distance of a thousand meters from the ground, digging parallel at this depth, the impact on the ground was almost negligible.

Three hours passed. Until he dug directly below the Imperial Palace, Han Kun didn't feel anything abnormal. This is an area repaired with a black-brown substance, Han Kun tried to whip it with a magic line, but the originally indestructible magic line only left a white mark on it, this kind of sturdiness is enough to deal with most emergencies, at least it can completely break the idea of infiltrating the imperial palace from the ground, although Han Kun is not without a way to forcibly break through, but he is not willing to do such a stupid thing.

"There's quite a lot of space under this imperial palace."

After using Dono to explore the underground and external structure of the imperial palace almost thoroughly, Han Kun probably had a bottom in his heart. As the so-called tip of the iceberg, the size of the underground area of the Imperial Palace can be much larger than that on the ground, Zhao Hankun estimates that the scope of this underground area has far exceeded the scope of the defensive technique, that is to say, even if you do not enter the Imperial Palace, but dig underground from the vicinity of the Imperial Palace, there is a high probability that you can also encounter this black thing.

Although it is not easy to collect this information, it at least gives Han Kun the possibility of breaking through from the front, from here if he penetrates the black wall in one go, he can indeed directly lead to the bottom of the underground area, but this is also Han Kun's last resort preparation, unless it is absolutely necessary, Han Kun will not use such a way to forcibly destroy the sneak.

After leaving the mark in place, Han Kun put away all the Dono, and then directly used the ventilation spirit ring to move to Melissa's room. Although three hours had passed, and it was already evening according to the time on the ground, it was strange that Melissa had not returned to the room, and it stood to reason that she should have finished dinner and returned to the room at this point, but at this moment Melissa did not come back, which made Han Kun suspicious.

The collar around Melissa's neck is not abnormal, and it can even use magic to connect with himself, Han Kun can determine Melissa's position at the moment, obviously Melissa is still in the Imperial Palace, but it has been in the same place for a while.

"Forget it, I'll go find her."

Han Kun shrugged his shoulders, and then used the ventilation spirit ring to move a short distance and move himself out of the door. Han Kun has almost explored the internal structure of the surface building of the Imperial Palace, and he is basically familiar with finding Melissa. And as long as the cover with magical power does not collide with a certain general head-on, it is impossible to be detected at all.

When Han Kun walked up to Melissa, he actually found that this guy was sleeping on his desk. This is a fairly rare thing, after all, this guy has taken a long nap at noon, so he will not fall asleep unconscious after only a few hours in the afternoon.

Seeing that there was no one around, and there was no magic monitoring, Han Kun decided to wake up Melissa.

"Hey, wake up, don't sleep, what time is it."

Han Kun pushed Melissa's shoulder hard, and with the shaking of her body, Melissa finally woke up from her sleep.

"Hmm....... Right now...... What time is it and why am I falling asleep? ”

Melissa woke up from her sleep with sleepy eyes, but when she looked around, she didn't see anyone.

"It's me, why are you asleep here?"

Han Kun's familiar voice came from his ears, but Melissa didn't see Han Kun's voice and shadow, which was also reasonable. After all, the location where he is now is the auditorium, and there may be no one around, so he gave Han Kun the opportunity to come forward.

"I want to ask you, but since you don't know anything, I'm afraid it's useless for me to ask. You go to dinner, and as for sleeping, there is time at night. ”

"Okay."

Melissa rubbed her forehead slightly, then got up and prepared to head to the restaurant.

Along the way, the surroundings were a little too quiet. Although Han Kun was still here for the first day, so he didn't realize it, Melissa was vaguely aware that something was wrong.

"Today, it seems a little quiet around."

Although these words were said to Han Kun, Melissa did not get a reply from Han Kun, which is also a matter of course. After all, in such a public place, the response is tantamount to revealing one's identity.

Unexpectedly, until she entered the dining room, Melissa still didn't see a maid, which is a strange thing. Usually a bunch of maids are waiting here to dine on their own, but not only is dinner not prepared today, but not even a single maid has been seen.

"Something's wrong."

Han Kun's tone was quite solemn.

"I know without you saying it."

Melissa also sensed that something was wrong, and she immediately ran to the kitchen, which did not take much time on the way because the distance between the kitchen and the dining room was not far.

What Melissa saw was a maid who had fainted to the ground. The maids seemed to lose consciousness in an instant and fell to the ground at the same time, and Melissa didn't even dare to approach them, only watched from a distance.

"These people seem to have just fallen asleep, and from the outside, they are fine, and their life characteristics are still there, but whether they can wake them up is another matter."

Han Kun's voice suddenly appeared in Melissa's mind, it was a voice that he used magic to generate directly in Melissa's mind, so it would not be heard by others.

"Are you sure you didn't do this?"

"Why did I wake you up?"

Han Kun's rhetorical question made Melissa choke, but his reasons were quite sufficient, and Melissa couldn't find any fault.

"So what now? Trying to wake them up? ”

"Cold salad. Anyway, this has nothing to do with me, but looking at it like this, it is likely that the entire Imperial Palace has fallen asleep, and I would like to know who has such a ability to make everyone fall asleep without knowing it, so that they can dive into the ground without any flaws. Really, how did I miss such a great opportunity? ”

Melissa couldn't help but pout. Unexpectedly, this guy not only thought about himself, but also kept thinking about the bad idea of sneaking in, but thinking that Han Kun himself was also a sneaker, Melissa's heart was also a little relieved.

After thinking about it for a while, Melissa chose to walk quickly to the side of a maid and shake her body vigorously, but she didn't expect that even with such a violent shake, the maid didn't react at all.

"Wake up! Wake up! ”

Even yelling so loudly in the maid's ear couldn't wake her up, and Melissa had no choice but to give up.

"It looks like I can't wake up. But I'm curious how you got called so easily? ”

"Maybe it's because I don't lack sleep myself."

"Someone didn't sleep all night last night."

"It's not because of you!"

Unexpectedly, Han Kun let out a shameless chuckle, and what was even more shameless was that he deliberately let this burst of laughter enter Melissa's mind, so that Melissa couldn't listen to it if she didn't want to.

"That's it! I'll have to check what the others are doing, and hopefully anyone else is as awake as I am. ”

"Aren't you afraid of running into an intruder head-on and being killed?"

Han Kun's words made Melissa pause, but soon she said firmly:

"I'm not afraid, anyway, I'm already your hostage."

"Good fellow, use me as a shield? Are you really going to protect you for that poor piece of information you know? ”

"I don't want your protection."

As if in a rage, Melissa walked straight out of the kitchen, slamming the door loudly.

"This guy, don't you know that the louder the voice, the higher the likelihood of provoking others? But it's okay, I'm going to see who can grab something from me right under my nose. ”

Han Kun let out a cold snort and followed behind Melissa.

Inside the Imperial Palace, there is a place called the Cabinet, which is where some of the powerful people live, and it stands to reason that Melissa should also live here, but she really doesn't like the gloomy atmosphere here, so she moved out early, and Melissa's uncle also lives in the depths of the Cabinet. Not surprisingly, Melissa's uncle should have been in the room at this time.

In the cabinet, there was silence. However, Melissa, who has not been here for too long, can't remember whether it has been like this here since before or whether it is very quiet because of an accident, everything will not be revealed until Melissa opens the door of the first room.

Melissa was the first to go to her uncle's room, and when this kind of sudden situation happened, of course, the more capable people are, the higher the probability of being awake, but long before entering, Han Kun had already used magic to probe this building. There are no living creatures inside the building.

"It's strange that Uncle isn't here."

Melissa searched all corners of the house, but she couldn't see her uncle.

"Don't look for it, he's not here. I've surveyed it with my magic, and there's still magic left here an hour ago, and apparently your uncle is awake, but I don't know where he went. ”

"That's good, I'll check the next one."

"No need, I've already surveyed it all with my magic, except for the three houses that are still empty, and the others, like the maids, are asleep."
