"Hey, what are you doing, I have a heart, you can't explain it to me, stop it, I'm afraid that the firewood knife will come." Li Mu kept shouting.

"Hmm, don't move, don't move." Erwin said vaguely. "Ah, the fresh blood, the strange taste, it's so addictive, I really want to keep drinking."

"Hey, I'm going to be sucked dry, shut up." Li Mu shouted.

A burst of red light rose from the two of them, and runes wrapped around the two of them, and a large amount of light swirled around the two of them, and the red light dissipated after a moment. Erwin took two steps back, "Alright, the contract has been rewritten, and now we are completely equal. Although the soul bond formed by the blood contract cannot be dissolved, you just need to follow your will to assist me. Help me reclaim my castle. ”

"Don't worry, I'll pay you back...... Including this one. Li Mu said firmly.

"Well, then I'm looking forward to your performance, I didn't expect you to be such a weirdo, it's a pity that you would give up your proud identity for that ethereal freedom." Erwin shook his head regretfully.

"What proud identity?" Li Mu was a little puzzled.

"As my servant, of course. You must know that becoming a servant of the noble true ancestor is an identity that is the envy of countless demons, and you will give up this luck, oops, it is really indifferent. Erwin said, covering his mouth and chuckling.

"Who likes to be a servant, although there are many people who shout to be knights, but they are only talking." Li Mu retorted.

"Oh yes, I haven't left the castle since I was born, I've been learning from books all these years, but I didn't expect that the human world has changed in the past few hundred years." Erwin cupped his chin in one hand in thought.

"It turns out that the eldest lady who is locked up in the castle and doesn't know what is going on in the world, no wonder she has such a temper, and she is going to bring a drag oil bottle again." Li Mu sighed.

"Hey, don't think I didn't hear it, although I'm optimistic about you, I'm going to be angry." Erwin crossed his waist, "You don't have to worry, as long as I get back my lost power, I'm invincible." The only ones who can surpass the vampire True Ancestor are the previous Six Demon Kings. You can rest assured. Erwin gave a reassuring look.

"I can't feel at ease, okay?" Li Mu held his forehead with one hand.

"Alright, you go to sleep, I'm going to rest too." Erwin waved his hand at Li Mu, "Sure enough, eating and sleeping is the most comfortable thing in the world." ”

"I really can't have too much confidence." Li Mu reluctantly walked towards the bedroom next to him.

Early the next morning. Under Mei Yi's envious and teasing eyes, Li Mu and Erwin finished a very hearty breakfast. Subsequently, Li Mu and Erwin made the final preparations before departure.

"We're going to take the castle, what should we do next, go straight to that castle?" Li Mu looked at Erwin, and understanding the employer's wishes was the key to receiving praise.

"No, that castle has a powerful barrier, which was originally only used to hide people's eyes, but now it seems to have been strengthened, and it may be very difficult to raid there without me regaining my strength."

"Oh, then, what are we going to do now? Look for your lost power, but even if we know the magic is endless in the castle. Do you know the secret passage to the castle? Li Mu showed an interested look.

"No, the power isn't in the castle, I can feel it, it's just hidden somewhere on this floating island. One of them is not far from the town we are in. Erwin said with his eyes closed.

"In that case, it's easy to do. So I can interject, oh no, is it a chime? Li Mu showed a curious look.

"Since it is for the sake of you to ask for advice so sincerely, I will kindly answer you, okay, you ask." Erwin had a proud look on his face.

"Now, you said you were a vampire, right, but how do you walk around in broad daylight, isn't the sun a deadly nemesis for you?" Li Mu showed a puzzled look. He had seen many vampires, and the vampires of each world were not quite the same, so he was also curious about Erwin's racial setting.

"It's really hard for me every morning. It's sleepy, the sun is dazzling, and the rooster crows so loudly," Erwin said, with a helpless expression.

"That's just you're lazy," Li Mu cast a disdainful look, "Wait, the rooster crows?" You're still raising roosters in the castle? Li Mu felt as if he had discovered something unusual.

"What's wrong? I like it, can't I? Anyway, the claims that we are afraid of the sun are just rumors, but our true strength will not really be revealed until it is true at night. Erwin hugged his shoulders with a helpless expression.

"Well, since you can walk freely during the day, it's no problem, you just need to be in charge of the position of the sensing power, and I'll take care of the rest."

"Then I'll wait and see, come with me." Alwin shrugged his shoulders and floated to his feet, heading out of town. Seeing this, Li Mu hurriedly followed.

The two of them came to the foot of a mountain on the edge of the floating island, at the foot of which was a gate made of rock with intricate carved patterns. It's just that because no one has taken care of it for a long time, this place seems to have become desolate and abnormal, and all kinds of plants and vines have climbed all kinds of columns.

"What kind of place is this, what kind of underground facility it looks like." Li Mu looked at the surrounding situation and then said.

"The Sykendem Pit, the ruins of a millstone pit built by Noam, the goblin of the earth, in ancient times, but after the veins were exhausted, Nome seems to have migrated to another floating island, and it has been abandoned for many years now." Erwin explained.

"Oh, what are you bringing me here for? Could it be that some of your power is hidden here? Li Mu looked at the deep pit and said.

"Well, the aura of power I felt near the town seems to come from here, I feel it, right in the depths, and although it's only a part of the power, I can really feel their presence." Erwin closed his eyes and felt it carefully, and said with certainty.

"Since this place is listed as a subject of suspicion, let's go in and explore." Li Mu nodded and took the lead in walking towards the inside of the mine.

"Well, let's go." Erwin also nodded and walked in with Li Mu.
