With Tang Bai's words, the heavy stone door that was tightly closed suddenly trembled again, and the tremor amplitude was greater than before. Under Phil's intently gaze, he moved away to the left little by little, revealing a swarthy cave behind him.

"That's it?" Phil's inquiring gaze swept Tang Bai.

"Maybe, I need a little more confirmation before I get in." Tang Bai walked towards the wall with a torch nearby, stretched out his hand to scoop the torch in his hand, and walked as he went.

"What confirmation? Isn't this door already open? Phil looked puzzled.

"You're advanced." Tang Bai didn't explain, but shook his head and gestured to Phil.

"Okay, okay." Phil raised his hands and made a gesture of surrender. He didn't pick up the torch on the other wall, the darkness didn't affect vampires as much as humans. They are able to have excellent visibility even at night.

Physique, mood, everything is enhanced and amplified when turning into a vampire.

"Don't rush in yet, Phil." Seeing that Phil had stepped into the cave and wanted to go inside, Tang Bai immediately stopped him.

When Phil heard this, he immediately stopped moving forward, and turned to look at Tang Bai with a puzzled face.

"Get out. Let me see if you can get out of it. Tang Bai put his wand between his arm on his left chest, and the palms of his two hands were upward, and he waved his palms at the same time, making a gesture to Phil.

"You're experimenting with me?" Seeing this scene, Phil, who has always been clever, immediately guessed something. His face looked a little unpleasant in the firelight.

"I have to confirm that. Check if the vampire can get out of this door. I will have all the caution I should have. Tang Bai nodded frankly.

"It's terrible." Phil, who had always thought that he had gained Tang Bai's trust, involuntarily lowered his mood. He stepped out with his feet outstretched, without any hindrance.

The seal of this space has indeed disappeared.

"Not at all! I don't know if the spell here is for all people or creatures with extraordinary powers. You're trapped, and I can still find a way to free you. But I'm stuck with the dragon, and that doesn't match my plan. Tang Bai strode into the cave.

"I think you must have enough blood, don't you?" Phil rolled his eyes and followed.

"Yes, it's enough for you to be a wine here, and drink heartily for a month and a half." Tang Bai walked forward with a torch and replied without looking back.

"You should have told me beforehand, at least remind me, so that I can be mentally prepared." Phil muttered aggrievedly.

"Come on! If I tried to deal with you, Phil, you wouldn't be alive now. We're going to hurry up and find the vampires here and get them out. Tang Bai unceremoniously blocked Phil's aggrieved complaint and said.

"Hurry? Why? Phil's voice echoed through the cavern.

"Hurry up and get out while we can get out." Tang Bai had already seen a withered, shapeless vampire in a corner.

"Didn't you break the spell?" Phil suddenly became nervous when he heard this.

"The effect of this potion is just an erosive effect. It can open a small gap in a spell, but after the potion has been depleted of energy, if the spell is strong enough and has another source of power to replenish it, it can revert to its original state, closing the gap that the potion has eroded. So," Tang Bai threw the weak withered vampires who couldn't even move their fingers on Phil behind him, and ordered, "Please take them all out as soon as possible." One does not fall. ”

After exploring the entire cave roughly and finding no other vampires, Tang Bai turned around and left the cave.

"What are we going to do next? Do you feed them blood? Phil put the last dry vampire on the wall, lined up with a row of vampires, took two steps back, and looked at the pair of red and bloodshot eyes, mixed with pleading and desire, he turned his head to look at Tang Bai with some hairiness in his heart.

"Hey, twenty-five vampires in all, good. You can also have a drink with them if you like. Tang Bai inserted the torch into the crack in the wall near the vampire again, counted the flames, and then took out a potion rack out of thin air. The shelves were lined with twenty-seven vials of viscous blood-colored liquid.

Phil took the blood-colored bottles in his hands one by one, walked over to the withered vampires, crouched down beside them, pinched their jaws, and poured blood into the bottles for them one by one.

The vampire who was infused with blood first regained the wriggling of his lips, and then his fingers also regained their ability to move, and his dry and wrinkled, gray-looking skin also became plump and healthy as the speed of blood sucking increased.

After one vampire regains his ability to suck blood on his own, Phil goes to take care of another vampire who is still dry.

Tang Bai was not idle during this period, he used a thick and solid, beehive-like ice wall with holes to seal the entrance of the hole. The holes in the ice walls are deliberately exposed to bring in air from the outside world. So that this cave, which was a little cramped after being filled with nearly thirty people, would not cause the air to be thin.

Building such a beehive-shaped wall wasted some of Tang Bai's time. By the time he had done all this, the vampires, who had been looking like corpses before, had regained their mobility one by one and stood up with their hands on the wall.

"Is it restored? That's great! Do you have anything to say to me, the one who freed you from decay and pain? Tang Bai spread out his arms in a hug and said with a smile.

"What do you want us to do?" A female vampire who looked dignified and showy, with a face leaning towards the East, stepped forward, perhaps because there had been no blood for decades, or maybe the blood she had just taken was still turning into energy to restore her failing body, so the woman's voice spoke with a thick hoarseness, as if her vocal cords were damaged.

"Nothing but allegiance." Tang Bai tilted his head, and said in a soft but firm voice: "I need you to do things for me." ”

"What if we refuse?" Another male voice rang out.

A man with unkempt hair, covered with thick dust, and a gloomy face crossed the female vampire who spoke first, and looked at Tang Bai greedily with blood-colored eyes.
