Ye Feng flicked his finger on Jiang Yixue's head and said, "Silly girl, this is Dr. Ludo. He is the only one who knows where the central control is. Once we find the central control and turn it off, we can remove the tube and save the blood."
Ye Feng carried Dr. Ludo to the blood collection plant.
Dr. Ludo slowly regained consciousness and looked at Ye Feng in surprise: "Who are you and what do you want to do by capturing me? If you want to drink fresh human blood, just drink it. This jar is full of it."
"Tell me where is the central control?"
Dr. Ludo thought that Ye Feng just wanted to steal fresh human blood. The blood produced by the Blood Demon Sect was very popular among the demons and was a very important business opportunity, so it was reasonable for someone to come secretly to steal it.
But when Dr. Ludo heard Ye Feng say where the central control was, he became alert: "Why are you asking about the central control?"
"I don't want blood, I want these blood slaves."
"Ah, do you know where this is? You think you can steal the blood slaves by pulling out the tubes? This is the territory of the Blood Demon Sect. Elder Xuelun and Elder Xuechi are in the villa in front. Aren't you afraid of death?"
Elder Blood Wheel, Elder Blood Pool and the Blood Demon Sect are very notorious in the Nine Demon Realms. Although Ye Feng doesn't know it, he can feel it from the respectful way Dorona treats Elder Blood Wheel and the fear in her look.
Ye Feng smiled faintly and said, "I don't care about Elder Xuelun or anyone else. I just want you to tell me how to turn off the central control. Otherwise, I will chop off your head with one sword."
The Thunder Sword in Ye Feng's hand flashed with golden light, leaving a light bloody mark on Dr. Ludo's neck.
Dr. Ludo is not only proficient in human blood research, but also in weapons research. Seeing that Ye Feng's weapon could cut a bloody mark on his neck with just the sword light, it must be more than just sharp.
He was surprised and said: "Xianling, this is not a magic weapon, it is a fairy weapon, who are you?"
Ye Feng sneered: "Don't worry about who I am, whether you want to live or die."
Dr. Ludo swallowed his anger and said, "The central control of each blood collection room is on the roof. As long as we turn off the magic crystal circuit on the roof, we can turn off the central control. Then we can unplug these tubes."
Ye Feng said to Jiang Yixue, "Yixue, let's go upstairs and turn off the central control. Not only turn it off, but also destroy it so that they can no longer use it."
Jiang Yixue said excitedly: "Okay, let's go now."
Ye Feng used some ropes from the Medicine King Ring to tie Dr. Ludo up into a bun, carried him on his back, and jogged to the roof.
There are more pipes on the roof, leading one by one to the downstairs. Ye Feng saw a thick pipe and guessed that it was the pipe of the central control system.
Although he had never seen the central control system, Ye Feng saw a magic rune array on the roof. It was the gathering place of all the pipes, and there was a thumb-sized purple crystal stone emitting a faint light.
Some energy from magic crystals is rotating back and forth in the magic rune array, and that magic rune array is probably the central control system.
Dr. Ludo didn't want to tell Ye Feng what the central control was, but when he saw Ye Feng staring at the magic talisman array, he knew that Ye Feng was not easy to deceive. If he really wanted to deceive him, he would probably end up in disaster.
"Dr. Ludo, your chance to survive has come. Tell me how to shut down the central control."
Ye Feng's judgment was correct. The magic array inlaid with purple crystals and focusing on many pipes was the central control system of the blood collection factory.
Dr. Ludo said in a boastful and warning tone: "That's it, just turn it off. But I want to warn you, this central control system is full of energy, it is not something that ordinary people can turn off. It will produce a reaction force, this force is very strong and can be fatal."
Ye Feng showed a trace of disdainful sneer: "Thank you for your concern."
A flash of sword light flashed from the Thunder Sword in Ye Feng's hand, and he slashed it down fiercely. Then the magic talisman formation emitted a counterattack energy, like a surging wave.
However, the powerful energy was shattered into pieces by Ye Feng's spiritual shield.
Seeing that the central control system he had worked so hard to design was destroyed by Ye Feng, Dr. Ludo showed a look of heartache. At the same time, he was secretly surprised. If this central control system was directly destroyed, it would automatically generate counterattack energy. This kind of energy could only be resisted by a Demon Lord of at least the seventh level of magic power, but Ye Feng easily blocked it.
He became more and more confused about Ye Feng's identity.
"You actually destroyed the central control system in one go. Who are you?"
"Don't worry about this. Is there a central control system like this on the roof of every building?"
Dr. Ludo glared at Ye Feng hatefully, keeping his mouth shut and saying nothing.
"Hurry up and tell me, otherwise your head will be like your central control system. If I cut it, you know the consequences."
Ludo glanced at the Thunder Sword in Ye Feng's hand and was shocked by the dazzling sword light. He said helplessly: "Yes, every building has such a central control system."
The night was even more violent on the rooftop. The corners of Ye Feng's clothes were rustling in the night wind. There were a total of six buildings, and he had to destroy the central control by himself.
Ye Feng measured the distance between each building. They were not far apart. If he went downstairs and then upstairs, that would be too troublesome. It would be better for him to fly directly to the top of the building with a flying sword.
But Ye Feng was worried that the light of his Thunder Sword was too dazzling and would be discovered by the demons, so Ye Feng smiled and did some stretching exercises.
"You don't want to use the flying sword?" Jiang Yixue guessed Ye Feng's intention.
"In order not to alert the enemy, I want to jump over. This distance is enough for me to jump over."
Hearing Jiang Yixue mention the flying sword, Lu Duo showed a look of horror: "You are the Golden Immortals? Impossible, you are clearly from the demon clan, how could you use a flying sword?"
"If you know less, you can survive. If you know too much, you will die."
Ludo was so scared that he immediately shut up and pretended he heard nothing.
The ice bow in Jiang Yixue's hand immediately took shape, the bowstring trembled, and an ice arrow shot out at a rapid speed.
"How about I give you a ride with my frost arrows?"
Ye Feng and Jiang Yixiu had already been in perfect sync with each other. He jumped high into the air, like a night owl, and his speed was surprisingly the same as that of the ice arrow.
Ye Feng lightly tapped the ice arrow with his toes, and the ice arrow generated a boosting force, sending Ye Feng to the roof of the building opposite.
Jiang Yixue saw Ye Feng flying over like a bird and clapped her hands excitedly.
"Brother Ye, you are great."
Seeing Ye Feng flying to the roof of another building, Ludo showed a look of surprise and admiration in his eyes.
Ye Feng also found the central control system on the roof of the second building. He raised his sword and destroyed the central control system composed of the magic talisman array.
Ye Feng followed the same method and destroyed the central control systems of all six buildings.
When he reached the sixth building, he saw four hellhounds and more than a dozen Blood Demon Sect disciples forming a circle and surrounding Xiaobai.
