The other three vampires remained silent. What happened to Vincent also shocked them. Only by completely obeying the black-robed boy would they have a chance of survival. They could see it very clearly.
"Oh? Isn't this equivalent to a curse?" Yao Min blurted out.
"The Curse? Is it the thing worn on the head of the god monkey in Chinese mythology?" Ace speaks Chinese very well, and he has a certain understanding of the mythology.
"The god monkey wears a golden hoop, and the spell to control the hoop is the magic spell." Yao Min corrected him.
"It sounds good, but how effective is it? You have to try it. Ace, you can use the blood oath now to pledge your allegiance to... me!" Xia Yan said. He originally wanted Ace to pledge his allegiance to Yao Min. But having a vampire by his side might not be a good thing for Yao Min.
What's more, he didn't want a handsome foreign guy to be by Yao Min's side, even if it was a vampire and a slave who swore allegiance!
"Yes!" Ace was unwilling and helpless, between life and dignity, he chose the former.
Xia Yan loosened the rope, released Ace, and tied the other four vampires together again. The skeleton soldiers closely followed Ace, who was temporarily free to move. As long as he made any changes, the skeleton soldiers could immediately suppress him.
"Let's start." Xia Yan said.
"Yes!" After letting go of the rope, Ace confirmed that he had no chance of escape, and could only despair completely. He stretched out his right index finger, popped out the one-inch-long sharp claw, gestured at his left chest, and slowly pierced into the flesh until the entire sharp claw was pierced in.
Pain appeared on his face, and he was chanting words. On his index finger, there was a slight glint of blood.
After a while, Ace slowly pulled out the sharp claw from his chest. Xia Yan was surprised to find that the sharp claw was hollow. At this time, a tube of dark red blood was sucked into it, which was Ace's painstaking effort.
After the sharp claw was pulled out, some blood oozes from the wound, and then it closes up quickly.
Ace raised his arms high and began to speak English in a strange accent.
"Great Cain, please witness the pious oath of your descendants!" Yao Min simultaneously translated for Xia Yan. The medical school's top students have read countless original medical works in English, and Xia Yan's English level has exploded by more than ten blocks.
"Your descendants hereby swear with the blood of the heart, allegiance to any life that has the most precious blood, dedicate my life to him, let him control..." Ace continued to swear loudly, and Yao Min continued to interpret simultaneously.
When this period of oath finally came to an end, Ace's palm had a dark red crystal the size of a soybean, like a gem.
"Master, please grasp my vowed blood crystal!" If Ace was still unwilling to show resignation just now, he has completely lost this emotion now. He knelt down in front of Xia Yan, holding the little blood crystal with both hands. Jing, presented in front of Xia Yan, was extremely respectful and obedient!
"Is this thing really useful?" Xia Yan picked up the blood crystal and found that it was very hard, not much different from real gems. He pinched it with his nails, but no marks were left.
But after pinching like this, Ace clutched his chest and screamed, "Master, spare me!"
"Really?" Xia Yan was taken aback, "Are you acting?"
"No acting, please forgive me, master!" Ace continued to yell.
"Let me try!" Yao Min said, and Xia Yan handed the blood crystal to her.
Yao Min carried the blood crystal behind her back and said, "This way we can test whether he is acting or not!"
"Miss Min is smart!" Xia Yan gave a thumbs up and pinched the blood crystal behind her. Naturally, it was impossible for Ace to see it. If he still reacted like this, it would prove that the vowed blood crystal would indeed affect him.
Ace was originally a white man, but when he saw the blood crystal falling into Yao Min's hands, his face became even paler.
Seeing his terrified look, Yao Min felt relieved, and pinched the blood crystal hard behind her back.
"Ah!" Ace let out a miserable cry, rolled on the ground, pressed his hands tightly to his chest, wishing to take out his heart.
"It's really not acting!" Yao Min was overjoyed, and pinched his back again, and Ace continued to scream and roll. The other four vampires were sweating profusely, feeling the same way.
"Xia Yan, can you give me this thing?" Yao Min said with satisfaction, "I want to make a hole in it and make it into a pendant. By the way, I will take a vampire under his wing. If anyone comes to pester me again, let the vampire take care of him." ,whee!"
"Doctor Yao, please forgive me, please forgive me!" Ace was so frightened that he turned up and knelt down regardless of the pain in his heart, "Master, please forgive me! Master, please forgive me! I will die of pain if I wear a hole, and I can't be your subordinate anymore." !"
"Sister Min, do you really want a vampire to follow?" Xia Yan asked cautiously. For Yao Min's thick nerves, he was completely convinced.
"Let's forget it. I don't have much fighting power. If this guy snatches the blood crystal away while I'm not paying attention, he will definitely seek revenge from me. I won't be able to handle it at that time, so you better keep it!" Yao Min sighed and returned the blood crystal to Xia Yan. Ace heaved a sigh of relief and collapsed on the ground.
"Sister Min, if you want, I can make him not dare to grab it." Seeing her regretful face, Xia Yan thought for a while and said.
"Xiao Yan, do you really have a solution?" Yao Min was overjoyed and hugged Xia Yan's arm.
"It should be possible." Feeling the soft touch on his arm, Xia Yan took out an ebony Horcrux, and stuffed the vowed blood crystal into the skull's mouth. The wooden skull moved slightly, squeezing the blood crystal tightly. Bite it, it won't fall out, a little soul fire inside licks the blood crystal.
"Master, what is this?" Ace's eyes widened suddenly, full of surprises: "It's so comfortable, this thing can increase my strength!"
"Really?" Xia Yan was also taken aback. Could it be that the fire of the soul has such benefits for vampires? He hastily checked the soul storage device, and found that the vowed blood crystal was really comfortable in the fire of the soul, just like steel being tempered by the fire. And according to Ace, he vowed that the blood crystal would benefit, and he himself would become stronger.
"So you are loyal to me, but you still took advantage of me!" After understanding this, Xia Yan couldn't laugh or cry.
"This is the luck that Cain bestowed on me, great master!" Ace knelt down deeply and kissed Xia Yan's shoes without hesitation, regardless of the dirt and blood on the shoes.
The blood race is a strictly hierarchical race. In front of ordinary people, Ace is superior, but once he donates the vowed blood crystal, he becomes a dog under Xia Yan's feet, without any psychological barriers.
Xia Yan's heart moved, and he sent a little mana into the ebony Horcrux, and the fire of the soul immediately became more intense, tempering the vowed blood crystal more fiercely.
