Shinoa Hiragi and Yuichiro arrived at the entrance of Sanguinem, where two Vampires still served as guards.
Seeing Shinoa Hiragi and Yuichiro, these two Vampires did not block their way, yet their faces still held contempt and disdain, their eyes revealing a scorn for humans.
They slightly stepped aside to clear a path, but their posture was as if they were granting a favor.
Shinoa Hiragi and Yuichiro were not angered by this and simply walked calmly into Sanguinem.
Before long, news of their arrival reached Lest Karr Karr's ears.
Lest Karr Karr found the two and led them into the laboratory.
The laboratory was filled with a faint smell of medicinal solutions. Various strange instruments and equipment were placed in every corner of the room. Complex ritual patterns hung on the walls, emitting a faint glow.
"Good day, you two. It's been over a week since we last met. I imagine you are prepared to cooperate with the research."
Lest Karr Karr smiled slightly, a hint of anticipation in his eyes.
Yuichiro nodded, but before the experiments began, Yuichiro needed to confirm some conditions.
He took a deep breath, his expression turning serious: "My demand is only one: save all races. If you cannot do it, I will not cooperate with you."
Lest Karr Karr was not surprised and nodded: "Humans can be directly resurrected. The other races will be resurrected in an angelic state. I will do my best to achieve this."
His tone was calm, but his eyes revealed a hint of difficulty.
Yuichiro frowned and shook his head: "Not 'do your best,' but 'must'!"
His voice was firm, his eyes revealing an unshakeable resolve.
Lest Karr Karr was silent for a moment, somewhat troubled. He couldn't even be sure if the seven sin keys would have enough power left to resurrect humans after reviving the angels, given the sheer number of humans.
He sighed and said: "Yu, if you don't understand the difficulties in this research, you can ask Shinoa Hiragi. Just preserving everyone's memories alone—we don't know when that research will succeed, let alone the fact that the number of humans is dozens of times greater than our numbers."
Yuichiro looked at Shinoa Hiragi beside him. Shinoa Hiragi was frowning, and noticing Yuichiro's gaze, she nodded.
She had also briefly looked at the ritual. Just understanding the function of each pattern couldn't be done quickly. Moreover, altering patterns in certain places to achieve the goal would further test the researchers' abilities.
She sighed softly and said: "This research is indeed very difficult."
Seeing Yuichiro fall silent, Lest Karr Karr tried to reassure him: "In any case, I will do my best. Actually, resurrecting human bodies like that is quite simple. However, it was precisely because Guren tried to save five humans back then that led to the apocalypse. I cannot be sure what would happen if all humans were resurrected."
His expression was somewhat grave, his eyes revealing a trace of worry. He was willing to resurrect humans, but his capabilities were ultimately limited.
Upon hearing this, Yuichiro realized that was what he was afraid of. He raised his right hand, and a ritual appeared. The ritual emitted a faint glow, as if containing immense power.
"If the apocalypse was caused by the Paradise, I have a way to avoid it. The Progenitor has already researched a ritual to shield from the Paradise's gaze."
His voice carried a hint of confidence. Even though it hadn't been tested, he felt a certain trust in the Progenitor.
Lest Karr Karr stared at this ritual. After a while, he rubbed his temples. His expression was complex, his eyes revealing a mix of surprise and relief.
"In that case, I can promise you."
He finally let out a sigh of relief, his expression relaxing a little.
Resurrecting humans was something his own research could potentially achieve.
After discussing some more details, Lest Karr Karr suddenly thought of something and said: "You can take some time to bring Byakuya Akane to Sanguinem. The sin key inside her cannot be extracted by you two alone."
His eyes held a glimmer of anticipation. That guy Luke stubbornly held onto the sin keys, not giving him a single one for in-depth study. He could only research them if Luke was present.
Shinoa Hiragi smiled and refused without hesitation: "You already have five sin keys. If we let you gather all the sin keys, we would be put at a disadvantage. After all, for the past few years, humans and Vampires have been on opposite sides."
Her smile held a note of firmness, her eyes revealing a hint of wariness.
Lest Karr Karr shook his head and persuaded: "To restrain us, you only need to hold onto one sin key. Plus, the ritual in Yuichiro's hands will take us a very long time to fully comprehend, so there's no need to worry about us turning against you."
Seeing that Yuichiro and Shinoa Hiragi were still unwilling, Lest Karr Karr could only sigh.
Not long after, Shinoa Hiragi was asked to leave the laboratory, leaving only Yuichiro there to cooperate with Lest Karr Karr in researching the ritual.
Shinoa Hiragi looked at the corridors to her left and right, unsure which way to wander. The more those Lower-ranking Vampires looked down on them humans, the more she wanted to parade in front of them.
Casually choosing the left corridor, Shinoa Hiragi began to wander aimlessly... Inside Krul's palace, Luke was hanging upside down from a chandelier, bound by ropes made of Dark Energy.
He struggled, protesting: "Unfair! I didn't use a sin key, so you shouldn't use Dark Energy either!"
His body swung left and right on the chandelier like a prank puppet.
On the throne, Krul controlled the Dark Energy with interest, a sly smile curling at the corner of her mouth.
Her eyes held a hint of teasing, as if enjoying this playful little "battle."
"I never said you couldn't use a sin key."
Krul's voice carried a teasing note. Her finger twitched slightly, and the Dark Energy ropes tightened a bit.
Luke, unconvinced, began swaying left and right, trying to break free from the Restraint.
His hair hung down messily, his eyes holding a trace of unwillingness: "Cheater, let me down. I surrender."
His voice held a note of helplessness, yet it didn't lack stubbornness.
Krul crooked her finger towards Luke, and Luke was brought before her by the Dark Energy. His protests grew weaker until they changed tone.
"I was wrong."
The resolve in his words was unparalleled, as if this was a predestined outcome.
Hum! Beside Krul's throne, the japanese sword where Ashera resided suddenly trembled. A surge of Demonic Aura emerged, coalescing into Ashera's form.
After absorbing Dark Energy, Krul no longer needed to rely on the demon sword absorbing Demonic Aura to maintain communication with her brother.
"You two are really lovey-dovey," Ashera's voice held a hint of teasing. His eyes swept over Krul and Luke, as if watching an interesting play.
Krul pouted, stubbornly saying: "Tch, this guy just has a cheap bone. Needs to be disciplined regularly."
Her expression held a touch of tsundere pride.
Luke pleaded for help: "Save me, Ashera! Your sister is trying to murder her husband... mmmph..."
Before he could finish, Dark Energy He was silenced.. His eyes held a trace of grievance, as if pleading his innocence.
Krul pretended nothing was wrong, but her gaze never left Luke.
A short while later, she flicked her finger lightly, and the Dark Energy dissipated. Luke was finally freed.
He rubbed his mouth and complained: "Krul, you're too harsh."
Krul shrugged, putting on an innocent expression.
"Who told you to always make me angry?"
Luke straightened his clothes and was about to walk out.
"Not playing with you anymore. Can't win."
His tone held a note of helplessness.
Krul did not Prevent Luke from leaving, only reminded him: "If you have nothing better to do, you can go ask the humans for the remaining two sin keys."
Hearing this, Luke opened a Light Screen he hadn't looked at in a long time.
Mission: Collect Seven sin keys (5/7)
Time Limit: None
Reward: Official Main Heavenly Dao Agent
Penalty: Stripped of Main Heavenly Dao Agent Candidate Status (You will only possess Golden finger authority within this Sub-world).
Hmm... Luke still didn't know what would happen after completing this mission.
However, Luke was somewhat afraid that once he obtained all seven sin keys, he might directly submit them, which would completely stranded the Progenitor's resurrection plan.
He frowned, feeling conflicted.
Luke said to Krul: "Good idea. Why don't you come with me to Shibuya?"
His eyes held a glimmer of hope, wishing Krul would accompany him.
Krul thought about it and felt it unnecessary. If the humans were unwilling to give them, even going together wouldn't make it easy to force them, which would destroy cooperation. Besides, as the queen, she still needed to handle some matters.
In the end, Krul still shook her head.
Luke sighed, putting on a somewhat cocky air: "It's fine if you don't go. After all, with my charm, I can get the sin keys myself."
Then Luke handed the four sin keys to Krul.
Krul frowned.
"Why give them to me?"
Luke said mysteriously: "I'm afraid something irreversible might happen once all seven sin keys are in hand."
Even though it was unlikely he would gather them all this trip, Luke still had to be prepared for the worst.
Krul didn't ask further and Collapse the four sin keys.
Luke left the palace and exactly bumped into Shinoa Hiragi, who was wandering aimlessly. Perfect timing! His eyes flashed with a hint of pleasant surprise, as if seeing hope.
However, disappointment soon appeared on Luke's face. The sin keys on him showed no reaction, meaning Shinoa Hiragi wasn't carrying any sin keys.
Then they must be in Shibuya.
A flicker of Loss crossed his eyes, but he soon returned to normal.
Shinoa Hiragi saw Luke and greeted him, her eyes holding a trace of curiosity.
Luke smiled back. Just as he was about to leave, he suddenly thought of something and decided to tease Shinoa Hiragi, wearing a mischievous grin.
"Shinoa, when are you and Yuichiro getting married?"
His voice held a teasing note, but his eyes revealed a hint of seriousness.
Zero-frame Opener?! Shinoa Hiragi's brain Short route from Luke's sudden question.
Her face instantly turned bright red, her eyes filled with fluster. Even though she usually loved telling risqué jokes, she felt somewhat shy now.
Luke patted Shinoa Hiragi's shoulder and said: "You must win Yuichiro over. I've been shipping you two for a long time. I believe in you. If you need a Wingman, you can come to me."
His voice carried a note of encouragement, but his eyes revealed a hint of slyness.
After saying this, without waiting for Shinoa Hiragi to react, Luke left, leaving only a blushing Shinoa Hiragi standing there in a daze.
Luke wandered around Shibuya. After chatting with Byakuya Akane, he learned that the humans were determined to keep the remaining two sin keys in their hands to maintain the initiative, so he temporarily gave up the idea.
For a long time after that, the world seemed to slowly get back on track. Human society in Shibuya had taken shape. Yuichiro would come regularly to cooperate with the research.
Shinoa Hiragi and the others focused their efforts on Shibuya.
Urd and Guren returned to Russia, and Lest Karr also went back to Germany.
After all, those were their territories. There wasn't much left for them to worry about in Sanguinem.
It's worth mentioning that Urd left a group of people under his command to assist Lest Karr Karr with the research. After accepting their help, Lest Karr Karr realized Urd's research in this area had reached a very mature stage.
Apart from the times when Luke stubbornly dragged her out to play, Krul spent her days in the palace handling affairs. When bored, she would ask Luke for a few manga or light novels.
Luke truly acted as a Wingman for Shinoa Hiragi, creating several opportunities for the two to be alone.
Even a blockhead like Yuichiro caught on. Their relationship wasn't explicitly stated, but it was mutually understood.
And so, six years passed.
Because Luke had never consumed human blood, he did not stop growing. By now, he was 183 cm tall, his face much more mature, having transformed from a juvenile into a youth.
Because he couldn't defeat Krul, Luke researched many ways to use the sin keys during these six years. He could now use the sin keys to contend Krul.
"Ah~~~ So bored~"
Luke suddenly complained. He lay with his head on Krul's lap, playing with a sin key in his hand.
Krul turned a page, saying irritably: "You really can't stay idle."
Krul didn't know why, but even after becoming a Vampire for so long, Luke's human emotions and sensations hadn't disappeared. Perhaps it was because he hadn't drunk human blood.
Having fed on Luke's blood for so long, she felt signs of her own human emotions reviving somewhat.
Just then.
Bang bang bang!
A knocking sound came. Luke and Krul turned to look and found the usually steady Lest Karr Karr looking excited.
"Success! I've finally finished optimizing that ritual!"
So fast?!
Both Krul and Luke were stunned.
They thought it would take at least a hundred years or so, but it only took six years for Lest Karr Karr to complete the research.
"Krul, quickly convene the Ancestor Council Meeting. Have Urd and the others come over. The New World is about to begin!"
He didn't pay any attention to Luke and Krul's posture. In the past, he would have Indispensable teased them, showing just how excited he was now.
Not long after, the Ancestor Council Meeting was convened. Urd and the others also felt it was too fast, but they figured Lest Karr Karr wouldn't lie to them.
"I will come as soon as possible."
After the meeting ended, Luke couldn't help but ask.
"Are you sure the ritual is perfected?"
Lest Karr Karr smiled confidently and nodded.
"Of course. Once Urd and the others arrive, we can start the plan. Yu is also very excited and has already rushed back to Shibuya to inform the humans."
