Start by Signing In with Infinite Dragon God

After enrolling, he could clearly feel the system's activation speeding up.

Because Kuoh Academy had several beings with the strength of High-class Devils. Including Rias, Sona Sitri, Akeno Himejima, and Tsubaki Shinra, there were at least four.

The magic power leaking from so many Devils could greatly accelerate the system's activation.

But he still felt it was not fast enough, so he joined the Student Council and stayed until the very end every day after finishing his work.

The reason he had not joined the Occult Research Club was simple. Rias truly believed that talent was everything. Compared to Sona Sitri, who valued ability and tactics more, Rias could practically be called a brute.

Just look at her future lineup: Rias's Queen was the daughter of a Fallen Angel executive and possessed both lightning and light attributes.

Of her two Knights, Yuto Kiba possessed a Sacred Gear with immense potential, while Genoa had already been a powerful Holy Sword User before joining.

Of her two Rooks, one was an almost-extinct Nekomata, while the other was an immensely powerful Norse Valkyrie.

Of her two Bishops, one possessed The Smile of the Holy Mother, making her a top-tier healer, while the other possessed The Magic Eyes of the World Annulment, another top-tier control-type Sacred Gear.

And finally, Issei Hyoudou was the wielder of a Longinus.

Therefore... knowing his own limits, Su Yang chose Sona Sitri.

With Sona, as long as one had ability, there was still a chance of joining the Student Council.

With Rias, if you had no talent and were not a Devil, did you still want to join the Occult Research Club?

Sorry, were you kidding?

In short, through a wager in a chess match, Su Yang successfully joined the Student Council.

A year after joining the Student Council, just now, Su Yang had finally successfully activated the system!

[Ding!]

[Loading complete! Congratulations, Host, on activating the God-Tier Sign-In System!]

[Ding!]

[Congratulations, Host, you have triggered a Location Sign-in! Sign-in Level: King!]

[Sign-in Location—Infinite Dragon God Ophis's head.]

[Sign-in Time Limit: 1 hour.]

"Damn!~"

Su Yang was an extremely calm person by nature, but even he nearly cursed under these circumstances.

Damn! Do you know that Ophis is probably under the protection of the Khaos Brigade right now? Are you telling me to charge into a group of Heroes and the Old Maou Faction just to die?!

"I think I need an explanation," Su Yang said quietly.

[Ding!]

[The location for a Location Sign-in is somewhere the Host will definitely be able to reach within the time limit.]

[Please pay attention to your surroundings.]

"Fine." Su Yang sighed. "But what is this Sign-in Level about?"

[Ding!~]

[Sign-in Levels are divided into five tiers: Bronze, Silver, Gold, Diamond, and King Sign-in. The rewards increase in quality accordingly.]

[The higher the Sign-in Level, the lower the probability of it appearing.]

[There is a daily sign-in every day. The more daily sign-ins completed, the greater the chance of triggering a high-level sign-in.]

"Uh... so this is the highest-level sign-in?"

Su Yang swallowed. He had to admit that he was tempted.

[Yes.]

Danger and opportunity coexisted.

Besides, in Ophis's eyes, he should be no more than an ant. It should... it should be fine, right?

Su Yang comforted himself.

"Whether I can complete the sign-in is something to consider only after I meet Ophis."

Su Yang decided to first calculate how far he could travel within an hour.

Taking Kuoh Academy as the center, if he ran at full speed, he could cover fifteen kilometers in an hour. In other words, the destination had to be within fifteen kilometers of Kuoh Academy's gates.

Accounting for winding roads, an irregular shape quickly formed in Su Yang's mind.

Ever since childhood, he had possessed astonishing Computational Ability, and his memory was equally remarkable. He easily projected a map of Kuoh Town into his mind.

Then... a few seconds later.

Su Yang opened his eyes again.

"The highest place around here should be over there."

Su Yang ran toward a clock tower.

That was where he could see as much of the surrounding area as possible!

"Huff!~~ Huff!~~ Huff!~~"

After reaching the top of the clock tower, Su Yang silently factored in other variables.

Variables that would affect the probability of where Ophis might appear!

He factored in Ophis's personality as she had displayed so far in High School DxD, the usual pedestrian flow in Kuoh Town, the various facilities in Kuoh Town that he remembered, and...

Perhaps this powerful Computational Ability was Su Yang's talent.

In an ordinary world, he would certainly have become an immensely wealthy tycoon. In fact, his current assets were already quite astonishing. But, but High School DxD was a world filled with Gods and Demons!~

Someone might start a fight, and he could die for no reason at all. Then the survivors would have their memories erased, leaving almost no proof that he had ever existed.

"Good! These are the places!"

Su Yang successfully deduced those locations. To him, it was not difficult at all.
