At this time, Lei Luo was standing alone outside the prison, while the two daughters, Tang Tai Yan and Chen Lingxue, were flying and searching in the royal city.

The three of them had no clue about the whereabouts of the remnant blood real person and the location of the dragon vein.

"The dragon vein is not in the Heavenly Prison, so where will this remnant blood real person be?" Lei Luo also wondered.

I didn't expect this person to be so cautious, even his own subordinates could be regarded as pawns, so it must be even more difficult to find this person.

Among the exercises that Lei Luo learned, he didn't have the magic power to find the dragon vein, he could kill people by himself, and if he wanted to find these non-existent things, it would be like an old death.

"Linglong, come out and help!"

He had no choice but to call his most trusted and resourceful helper to come out and give advice.

Lu Linglong slowly appeared beside Lei Luo, but as soon as this woman appeared, she began to look around, as if she had found something.

"Childe, there is indeed a formation in this entire royal city, I came out just now and was busy killing the enemy and didn't find it, now calm down and take a look, I can see it," Lu Linglong said slowly after looking around.

Hearing this, Lei Luo never thought that this woman would be able to see that there was a formation, but when he thought that he was a formation idiot and this woman was a genius, he was relieved.

"Can you see that there is anything wrong with this formation, or where is the person presiding over the big formation?" he asked quickly.

The top priority now is to find the remnant blood real person, this person must be the culprit sent by the sect to investigate, and at the same time, this person has been doing evil in the royal city for many years, and must be eliminated.

"This formation is very large, covering almost the entire royal city, I can only see a little bit of the formation now, and I still need to go to other places to check them one by one," Lu Linglong explained.

The formations are also large and small, and although the formation they are in now has no attack ability, it is extremely huge.

If you are only in one place, you can't even see the texture of the formation, let alone crack it.

"In that case, let's check as we go, you can lead the way!" Lei Luo understood what he meant, and then nodded.

Lu Linglong nodded, and then she started walking in one direction, but she sometimes stopped after walking a few steps, and then groped for something in some palaces or statues.

Lei Luo only knew some common sense about the formation, so naturally he couldn't help much, so he could only let Lu Linglong study it slowly.

"Someone's coming, it's still cavalry!" he said abruptly in one direction, and his tone was extremely strange.

It turned out that they had unknowingly walked near the gate of the city, and a large group of cavalry directly under the royal city rushed over, obviously taking him as an assassin who had trespassed on the royal city.

After the cavalry rushed in front of Lei Luo, one of the middle-aged men in armor rushed to the front of the group, and then ordered the whole team to stop.

"Bold thief, you dare to trespass into the royal city, and you won't be caught immediately!" the man in armor shouted loudly.

This person is a general of the cavalry directly under the royal city, and when he saw that Lei Luo was able to walk in the royal city with a swagger, he was naturally angry and wanted to capture the other party.

But to his surprise, the other party didn't react after hearing his words, not only did he not have the consciousness of being restrained, but he was also thinking about something while walking, and he didn't take so many of them in his eyes.

"Bold, dare to ignore us and others, who will capture him!" the man in armor shouted again, this time louder, obviously really angry.

As soon as he finished speaking, two cavalrymen dismounted and walked towards Lei Luo, drawing their long swords at their waists as they went, as if they were about to strike if the other party resisted.

"By the way, in the royal city, King Zhao!" Lei Luo suddenly shouted.

This can startle a group of people, including the armored man, and they don't understand why the people in front of them are not afraid when they see so many of them, and they also shouted out the name of their own king.

However, something that surprised them even more happened, only to see that the other party actually looked around a few times, and then as if he had suddenly discovered them, he showed a somewhat surprised look.

At this moment, including the armored man, their faces were darkened, there were so many people on their side, and the other party actually saw it now, is the other party blind!

"I remember that you seem to be the cavalry directly under the royal city, which of you has the greatest official position?" Lei Luo asked suddenly.

This question also surprised everyone, who had never seen such a madman, and actually asked this kind of question without any logic in front of them, and asked whose official position was greater.

However, someone really looked at the man in armor, obviously signaling the person in front of him with his eyes, and this person had the most official position among us.

"Thank you, I ask you a question, where is King Zhao?" Lei Luo thanked the person who showed him in his eyes, and then asked the man in armor.

This time, the armored man and the cavalry behind him were speechless, and they all looked at the boy in front of him with a stupid face.

"Look, someone, take him down for me!" the man in armor ignored Lei Luo's question and shouted sharply.

As soon as he finished speaking, the two dismounted soldiers directly drew their swords and rushed towards Lei Luo, which means that if you resist, we will really use our swords.

"Hey, I have to do it!" Lei Luo sighed lightly, then shook his head.

He didn't have any nonsense, and pointed to a side hall beside him with one hand, and a pale red sword qi was released from his fingertips.

After the loud "boom" sound, a quarter of this side hall was blasted into rubble by this sword qi, and countless broken corpses and house beams collapsed, the scene was quite spectacular.

Seeing that a large hall in front of him was directly bombarded by the other party, the man in armor swallowed a mouthful of saliva, and the swords in the hands of the two soldiers unconsciously fell to the ground.

"Run!" shouted for some reason, but the cavalry all turned around and fled.

What are you kidding, the person in front of you can have such destructive power without even moving his feet, and if he doesn't run, he won't be looking for death!

"Who said that the cavalry of Wangcheng was strictly disciplined, so they ran away?" Lei Luo shook his head and sneered.

Then another sword qi was released, and a large crater was blown out behind the cavalry, some of them rushed down without holding their horses, and many more were shaken back by the explosion gas wave.

"You haven't answered the question below, and when you answer the question, I'll naturally let you go!" Lei Luo's voice rang in the armored man's ears.

This scared the man in armor a lot, and the whole person fell off the horse because of fear.

Then when he saw a figure standing beside him, he was terrified, and his whole face was dark blue.

"Great, hero, King Zhao is in the royal city, and it is in the most central palace!" the man in armor said.

But as soon as he spoke, Lei Luo was also strange, didn't he say that King Zhao hadn't appeared for a long time, how could he still be in the palace.

"Then why didn't I see him?" he could only ask.

"The hero doesn't know, the king has built an underground secret hall under the palace, this underground secret hall is built quite deep, and the ground is covered with a rather special stone, so ordinary people can't find it!"

Lei Luo then asked several more questions, including how the man knew about these things, and the man in armor opened his mouth to explain.

In this way, after the two of them asked and answered, he also knew the reason why he couldn't find King Zhao.

It turned out that the underground secret hall was built by King Zhao more than twenty years ago, when the man in armor was still an ordinary guard in the royal city, and he happened to be in charge of supervising the craftsmen to build it at that time.

In this way, after the construction of this underground secret hall, the king of Zhao ordered everyone not to leak the news, and many craftsmen who participated in the construction at that time were ordered to die.

This is the reason why the armored man can know the whereabouts of King Zhao, and only a very few people in the royal city know that there is an underground secret hall directly below the palace.

"I see, okay, you can go!" Lei Luo waved his hand and let the people go.

Hearing this, all these cavalrymen, including the men in armor, spread their feet and began to run, running as far as they could, and some of them even used their strength to eat.

"No wonder it's so hard to find, no wonder there are rumors in the palace that there are man-eating monsters, no wonder Wenxiu was able to run all the way out of the palace!" Lei Luo looked at the palace in the center and said.

The gate of the palace was in front of him, and there was no obstacle between the palace and the gate, and one way could run out of the city.

That King Zhao ordered the construction of that underground secret hall, and the remnant blood real person must be hiding inside!

"Maybe that King Zhao is also practicing some kind of evil art, and maybe the Remnant Blood True Person and King Zhao are the same person, and the original King Zhao may have been taken away!" Lei Luo guessed.

After getting the news, he informed Lu Linglong, and then took out the messenger to inform Tang Tai Yan and Chen Lingxue, and he walked towards the palace first.

This palace is actually the place where King Zhao and the civil and military officials of the Manchu Dynasty discuss state affairs, but since the King of Zhao ignored the government, there is no one here, although there are people cleaning every day, but it still seems quiet and empty.

"Childe, the center of this big array is directly below this palace, about fifty zhang or so, and the center of this formation is also inside!" Lu Linglong said slowly after entering the palace to check.

After saying that, she looked around, obviously looking for some kind of secret door or something.

"Linglong, you don't have to look for it, hand it over to me!" Lei Luo stopped her.

Just when this woman was quite puzzled, she saw Lei Luo take off her shirt, then sit cross-legged, and began to close her eyes and breathe.

"Childe, do you want to!" Lu Linglong said in surprise when she saw this.

Lei Luo didn't reply, but instead ran the "Mountain Refining Body Decision" technique in his body, and an invisible wave of qi exploded and spread around.

However, this time the power of the qi wave was much smaller, and it only shook the walls around the palace into cracks.

Then he put a hand on the ground of the palace, and with his movements, it spread around the palace, and an earthy yellow ripple four or five miles wide spread out in all directions.

"It's a different place!" Lei Luo shouted in a deep voice.

When the range was controlled at this distance, he ran the exercises again, and then the ground within four or five miles began to collapse entirely.

Underneath these lands, streams of yellow energy were directly absorbed by Lei Luo in the center.

The sound of "boom" spread all around, and for a while, the entire royal city was full of smoke and dust, and the center began to collapse, and even inside and outside the capital felt this sense of vibration.

After about half an hour, a huge pit more than five miles wide was formed around the palace of the king, and all the buildings here were in ruins!
