===

After the blue and white panties were fitted, Ophis felt a wave of reassurance beneath her skirt.

So this is the purpose of the fabric under the skirt? Ophis thought she had gained

some knowledge.

Chiba looked up, his expression slightly complicated.

In truth, being hugged by Ophis just now didn't make him feel particularly

comfortable.

After all, Ophis was a flat-chested loli.

Although flat chests were quite rare in this world, they were still flat chests.

....

[Ding!~]

[Congratulations! Host has completed the villain sign-in!]

[Sign-in Level: Gold]

[Sign-in Type: Location Sign-in.]

[Sign-in Location: The panties of Infinite Dragon God Ophis.]

[Congratulations! Host has received the reward: Masterless Enhanced White Dragon

Emperor Dragon Soul.]

[Masterless Enhanced White Dragon Emperor Dragon Soul: A masterless dragon

soul that has progressed beyond the White Dragon Emperor, usable for artifact

upgrades.]

[Ding!]

[Detected a reward that can be fused. Does the host wish to fuse?]

"Fuse."

Chiba swallowed hard.

This system reward directly resolved his urgent need.

Originally, Chiba had chosen to hide the Red Dragon Emperor's cage hand to act

covertly, usually letting Agumon take action.

However, if his artifact could gain the ability of "White Dragon Emperor's Wings," he

could use the abilities of either the Red Dragon Emperor or the White Dragon Emperor

openly!

[Ding!~]

[Masterless White Dragon Emperor Dragon Soul fusion successful!]

[Congratulations! Host has obtained: God Slayer Tool—Dance of Red and White

Dragons.]

[Dance of Red and White Dragons: An artifact that fuses the dragon souls of the Red

Dragon Emperor and White Dragon Emperor, enhancing both limits. Can use abilities

of both the Red Dragon Emperor and White Dragon Emperor separately or together.

More effects can be developed by the host.]

....

"Roar!!~"

The sound of dragon roars echoed.

Behind Chiba, white and blue colors intertwined as a pair of ice-blue wings flickered in

and out of existence.

The white armor and blue gemstones were characteristics of the White Dragon

Emperor, corresponding to the red armor and green gemstones of the Red Dragon

Emperor.

A few seconds later, the wings fully materialized, emitting waves of ice-blue light

points.

"Chiba....."

Ophis called out Chiba's name, her calm gaze wavering once again.

Just now, Chiba's artifact had evolved right in front of her!

She could understand absorbing dragon souls for evolution.

What she couldn't understand was... why was there an extra dragon soul from the

White Dragon Emperor?!

"This is actually my ability; it allows artifacts and various items to evolve," Chiba

explained helplessly.

"Hmm....."

Ophis nodded without saying anything further.

She didn't care what Chiba's abilities were; as long as he could help her achieve her

goal of "killing the Red Dragon Emperor," that was enough for her.

"This is for you."

After thinking for a moment, Ophis extended her small hand and inscribed an

ouroboros symbol in the air.

Pushing her hand forward, the ouroboros symbol advanced toward Chiba's chest.

"This is a blessing from the Dragon God. With it, you can resist several attacks from

dragon gods in a short time. If you encounter danger, you can also use it to contact

me."

"Okay... I understand."

Chiba stroked the ouroboros mark on his chest.

At that moment, he felt like a kept man by a wealthy woman.

But... he had to admit that being kept felt really nice! Being kept by a wealthy loli felt

even better!

Sorry, Nao-san; you were right.

If it helps achieve his goals, what's wrong with living off someone else?

With Ophis's mark as a life-saving item, Chiba didn't even need to hide the Red

Dragon Emperor's cage hand anymore.

.....

After inscribing the mark, Ophis nodded in satisfaction.

"My estimation is that as long as you absorb another Heavenly Dragon soul or

several Dragon King souls, you can elevate the dragon soul within your God Slayer Tool

to sub-dragon god level."

"However, there's no rush for advancement; you are a demon with a long life. I can

wait until you are fully prepared before executing our contract."

"Hmm, I understand this point."

Chiba nodded.

Of course, he wouldn't challenge the Red Dragon Emperor without being prepared;

that would be asking for death.

Even if he advanced to sub-dragon god level, he didn't plan to take action against him

yet.

Killing the Red Dragon Emperor could wait until he reached dragon god level!

.....

Ophis moved her delicate little feet and prepared to leave.

"Chiba... remember to call me if you encounter danger. I will take my leave now."

"Okay, Ophis. I will actively call you when I face problems I cannot solve. But are you

sure you don't want to stay here a little longer?"

Chiba wanted to deepen his relationship with Ophis further.

"No need; my purpose for wandering outside hasn't been fulfilled yet~"

"What is your purpose for wandering?"

Chiba raised an eyebrow; he thought Ophis was just wandering around aimlessly until

she was attracted here by Asia's dragon-attracting physique.

"My purpose... I am looking for someone."

"Who?"

"The Biblical God or rather... remnants of the Biblical God... or perhaps...

descendants of the Biblical God?" Ophis switched between several terms rapidly.

Hearing Ophis's explanation made a glimmer pass through Chiba's eyes.

[Biblical God!]

Indeed, only beings of such caliber would catch Ophis's attention!

....

An hour later,

Chiba had learned all about what interested him from Ophis.

Ophis also devoured all the snacks stored at Chiba's house.

"Chiba... your gift... I really like it..."

Ophis lifted her blue and white panties and gave Chiba a thumbs up.

Accompanied by Asia's shy scream, Ophis transformed into a wisp of green smoke

and vanished before their eyes.

....

After bidding farewell to Ophis, Chiba immersed himself in thought and opened his

system interface.

In fact, when integrating Ophis's mark earlier, Chiba had heard a system notification

sound.

[Ding!~]

[Detected that host energy has met standards; officially activating "World Sign-in"

function.]

[Chaos energy absorption in progress...]

[Estimated absorption time: 24 hours.]

[After 24 hours, "World Sign-in" function will officially activate; please look forward

to it!]

"World Sign-in..."

Chiba was very satisfied with this World Sign-in function.

Because not only did it mean he could travel to other worlds but also that his sign-in

opportunities would double—his speed of becoming stronger would double too!
