How about upgrading the Harem King trait to the Rainbow level after accumulating enough materials next time?
Tatsuma suddenly had a bold idea in his mind.
From Limitless Potential and Devil God Bloodline, it can be seen that traits that can grow have a higher limit.
The Harem King trait, which increases its effect based on the number of infatuated individuals, is also a growth-type trait.
If there was any problem, it was that the Harem King trait not only increased Training effect but also added to charm.
As his charm attribute got higher and higher, the aura around him underwent some changes. Even if Tatsuma suppressed this aura in his daily life, it would still affect ordinary people around him.
"Mm..."
Just then, Est's voice sounded.
Tatsuma temporarily stopped thinking and looked aside.
Est had now woken up from her slumber, released his arm, and sat up.
Rubbing her sleepy eyes, Est stretched out her hands and wrapped them around Tatsuma's neck.
"Tatsuma, good morning."
"Good morning, Est."
Tatsuma stroked her head and led her into the bathroom.
After spending two hours washing up, Tatsuma helped Est change her clothes and took her out of the room.
Coming to the next room, Tatsuma saw that Yahweh was looking down and fiddling with a chess piece, on which a large number of Magic formulas were emerging.
Walking over and standing beside her for a while, Tatsuma asked thoughtfully, "Is this the Evil Piece you made?"
"Yes, it's currently just a semi-finished product, and there's still room for further optimization to improve its effect."
Yahweh's palm swept through the air, and all the extending Magic formulas retracted back into the chess piece.
"You came at the right time, I have something to ask you."
Tatsuma asked, "What is it?"
Yahweh said, "Referring to your previous request, I have now designed two versions of the Evil Piece."
"One is to strengthen a normal Evil Piece, allowing it to possess all the characteristics of an Evil Piece and significantly increase its strength."
"The other is to modify from the ground up, using your blood as the core to create a Evil Piece. Of course, a piece made this way can no longer be called an Evil Piece. Calling it a Tatsuma piece is more accurate."
While speaking, Yahweh took out a crimson Evil Piece and placed it on the table.
"This is the first generation Tatsuma piece I designed using your blood as the core."
"Compared to a normal reinforced Evil Piece, a Tatsuma piece is more effective, capable of strengthening the target from the inside out in all aspects, and even increasing potential."
"However, there's a problem. Not everyone can withstand your blood, at least Ultimate-class strength is required for successful fusion."
Tatsuma nodded. "As expected of me."
"I'm not praising you."
"I know what you mean."
Tatsuma picked up the two pieces and looked at them. Then, under Yahweh's bewildered gaze, he successively fused these two pieces into his body.
[Detected external power, convert to purple trait?]
[Detected external power, convert to red trait?]
Do not convert.
Tatsuma expelled the two semi-finished Evil Pieces from his body and put them back into Yahweh's hand.
"Next, let's focus on designing a Devil God piece."
Yahweh was confused. "Devil God piece?"
"Yeah, Tatsuma piece sounds weird, Devil God piece is more pleasing to the ear."
While speaking, Tatsuma took out a syringe from Yahweh's toolbox and drew a tube of blood.
"This is the material for making the pieces. My current blood is more suitable for designing the Devil God piece."
"No problem."
Yahweh took the syringe, suddenly frowned, and let out a surprised sound.
This blood... it seems a bit off.
She could clearly feel that the Evil Piece in her body was trembling. Affected by the Evil Piece, Yahweh indirectly felt a sense of oppression from this tube of blood.
A touch of holy light appeared on her fingertips, and Yahweh activated a divine art to analyze this tube of blood.
A few seconds later, the analysis finished.
Conclusion: Devil's blood, but the bloodline purity is far higher than the original Lucifer.
"Tatsuma, you evolved again?"
"Yeah, a little improvement yesterday."
"This isn't something that can be described as 'a little'."
Yahweh shook her head slightly, her expression a bit complex.
In the past, there were Devils whose bloodline purity reached the level of the original Devils after reverting to their ancestry.
But a situation like this...
Surpassing the origin of Devils, higher than both the original Lucifer and the Mother of Devils Lilith, is abnormal.
"Devil God piece... I somewhat understand why you named the new version of the piece this."
Tatsuma asked, "How is it? Can it be made?"
Yahweh said, "It will take some time, the tube of blood you just drew is stronger than before, and ordinary Evil Piece raw materials might not be able to withstand it."
Tatsuma said, "Time is not a problem, as long as it can be made."
He was researching the Devil God piece, partly to use it himself, obtaining high-level traits as material through conversion.
On the other hand, it's for Sakiko and the others, to strengthen their abilities and extend their lifespans.
As long as it can be researched, any amount of time spent is acceptable.
"Busy again."
Yahweh put away the syringe in her hand.
With the first-generation Tatsuma piece as a reference, modifying the underlying logic to create the Devil God piece is not difficult.
But in traits of materials, purification is needed.
Of course, purification is just the final method. Before that, there are other methods that can be tried.
Taking out a mask and putting it on, Yahweh completed her disguise.
"Let's go, we're going to Lilith. If we're lucky, maybe we can find materials suitable for making the Devil God piece from the Devil higher-ups."
"Then I'll look forward to your harvest."
Tatsuma snapped his fingers and activated Teleportation magic.
The surrounding scenery rapidly changed, and the three of them arrived inside the Lucifer Palace in the next instant.
Releasing his senses to probe, Tatsuma quickly found Sirzechs's location.
Bringing Yahweh and Est all the way to the top floor, Tatsuma pushed open the office door.
"Tatsuma, you're here."
Inside the room, Sirzechs was having a remote conversation with a blond young man via projection.
"Let me introduce you, the one on the screen is a deity of the Norse pantheon, Vidar."
"Vidar, this is..."
"Sirzechs, no need for introductions."
Vidar waved his hand and interrupted, "The famous Red Dragon Emperor, I recognize him."
"Compared to the legendary God of the Forest, I'm not exactly famous."
After a round of polite mutual flattery, Tatsuma looked at Sirzechs. "Where are Ajuka and Azazel?"
"After the meeting yesterday, Ajuka took Azazel to his secret base."
Sirzechs took out a nameplate. "This is the key to the door. Once activated, it can teleport you there."
"You go first."
Tatsuma handed the key to Yahweh, who was standing nearby.
Yahweh nodded, injected energy to activate the key, and her figure disappeared from the spot in the next instant.
Seeing this, Sirzechs reacted a beat slower. "She's the one who made the amulet?"
"Yeah, you can call her Rin Nanakura."
After giving Yahweh's alias, Tatsuma reached out and pointed at the silent silver-haired girl beside him.
"This one here is Est, the spirit I contracted in the Familiar Forest yesterday."
"Hello, Est."
Sirzechs gave a greeting.
He wasn't completely unfamiliar with Est. Through his conversation with Restia, he had learned more or less some things about Est.
Although Restia didn't know much, she did know basic information like silver hair and blue eyes.
After greeting Est, Sirzechs's gaze returned to the screen.
"What are you talking about?" Tatsuma leaned over and asked.
"The time for the talks." Sirzechs replied.
Not long after ending the civil war and establishing the Three Factions Alliance, Sirzechs, Michael, and Azazel jointly sent alliance applications to various pantheons, attempting to further establish a mythological alliance to maintain world peace.
Tatsuma had also heard about this matter.
Hearing Sirzechs say this, he instantly understood what the other party meant.
"The Norse Pantheon is willing to join the alliance? Then why is it Vidar? Shouldn't Odin be the one discussing this?"
"That old man is out of contact." Vidar's voice was full of resentment.
"Recently, the internal affairs of the Norse pantheon have all been handled by me on his behalf."
"I see." Tatsuma nodded thoughtfully.
Odin has a bit of his style.
Sirzechs said, "Tatsuma, Vidar and I are preparing to set the time for the talks after the summer break, and the location will be Kuoh Town. What do you think?"
"That's fine."
Kuoh Town is where the Three Factions Conference was held, and it holds special significance for the Bible Faction.
It is naturally very suitable for signing the alliance contract with the Norse pantheon, but...
