Chapter 688: I Saw You as a Brother, But You Want to Be My Son-in-Law

Javier Sinclair’s gaze fell upon his in-laws.

The two of them were badly injured. His father-in-law, in particular, had a cracked bone. His mother-in-law, on the other hand, wasn’t as seriously hurt. With her Divine Power for protection, she had only sustained minor injuries.

At this thought, he said, “You are indeed badly injured.” As he spoke, Javier Sinclair gently raised a hand, his palm aimed at the pair. A current of power flowed from him into their bodies. Just a moment later, their injuries were fully healed.

Feeling the change in his body, Noah Grant touched his chest in delighted surprise.

“Whoa! It doesn’t hurt anymore.” He raised a hand and circulated his Cultivation; the flow was completely unobstructed. “My injuries are healed! The Unrivaled Bear’s attack cracked one of my ribs, but now it’s good as new.”

“Holy shit! Bro, that move was slick as hell! You get a thumbs-up from me.” As he spoke, Noah Grant looked at his wife. “Honey, how are you?”

Elara Eastwood opened her palm.

“I’m fine now too, my love.”

As she spoke, she once again clasped her hands in a gesture of thanks toward Javier Sinclair.

“Thank you, Senior.”

Noah Grant was overjoyed.

“Thanks, bro.”

‘My father-in-law is calling me ‘bro,’ which is already more than I can handle. And now my mother-in-law is calling me ‘Senior’ with every breath. That’s even worse. I don’t need this huge seniority gap. I really, really don’t.’

Javier Sinclair said earnestly, “Please, don’t call me Senior. Since you consider me a friend, just call me by my name!”

Noah Grant clapped him on the shoulder and laughed. “Bro, you’re a real straight-shooter. I love dealing with people like that. The ones I can’t stand are those pretentious types who look down their noses at everyone. You’re my kind of guy.”

“Enough talk. Let’s head home now.”

“Bro, I’m treating you to a barbecue tonight. You know what barbecue is, right?”

Javier Sinclair nodded slightly. “Yes, I know.”

Noah Grant looked up at the sky, where a giant eagle of the Great Demon Level was circling at a low altitude, waiting. “Bro, is that giant eagle your ride? It looks so badass. It’s like the Rolls-Royce of mounts.”

Javier Sinclair nodded slightly. “I’m not familiar with the area, so I caught it to be my guide.”

Noah Grant was filled with awe.

‘Is this what a powerhouse is like? Casually grabbing a Greater Demon to act as a guide… Some people are just on a completely different level. He’s so damn strong.’

“The eagle is fast. Let’s get on.”

“Alrighty then, bro! Don’t mind if we do.”

As he spoke, the three of them leaped onto the giant eagle’s back one by one. The eagle let out a cry, circled once in the air, then flew toward the Eastwood Clan Grounds.

Guided by Noah Grant and his wife, the giant eagle soared over a swamp. It then crossed a mountain range and passed through an Array Barrier before finally entering the Eastwood Clan Grounds.

“The High Priest is back!”

“And the Young Clan Leader has returned!”

Javier Sinclair’s gaze fell upon Noah Grant and Elara Eastwood. ‘So, my father-in-law is the High Priest, and my mother-in-law is the Young Clan Leader of the Eastwood Divine Clan.’

‘He wasn’t surprised that his father-in-law had come to these Ancient Times from Earth. After all, he himself was standing right here. With the right fated coincidences, such things were possible.’

‘Crossing the river of time to arrive in this ancient era and meeting his father-in-law was a complete surprise. However, Javier Sinclair hadn’t forgotten his purpose for coming here.’

He was here to deal with the Seal left within Celeste Grant’s bloodline.

That evening, he casually brought up the matter. His approach, of course, was to say that a Sealing Skill had been placed in his wife’s bloodline and that he knew very little about such things.

Noah Grant was very enthusiastic and immediately asked what kind of Sealing Technique it was, saying he had done a lot of research on the subject and might be able to help.

As it turned out, he could indeed help.

But after hearing Javier Sinclair’s description, he scratched his head in confusion. “That’s really strange. What you’re describing sounds a lot like a new Sealing Skill I recently developed: the Function and Algebra Sealing Method. I just came up with it, and it hasn’t spread anywhere yet. Don’t tell me someone else had the same idea. No, no, that’s impossible… unless they’re from Earth, like me. That would explain it. The principles of this Magic can be used for both offense and defense; it has multiple applications.”

Javier Sinclair: “…”

‘Is it possible that you were the one who developed it?’

‘The Function and Algebra Sealing Method? A Sealing Skill from the Ancient Times involved something like this? No wonder I’ve never seen it before.’

‘Isn’t this just high school math from my wife’s home world? My father-in-law actually used it for this. And for some unknown reason, this Magic ended up being used on his own daughter.’

‘For a father to use such a Sealing Skill on his own daughter… it couldn’t have been to harm her. It must have been to protect her.’

Javier Sinclair glanced at him and asked, “Can it be undone?”

Noah Grant laughed. “Of course! You just have to learn functions and algebra to undo it. It’s super simple. Bro, if you want to learn, I can teach you!”

‘Learn functions and algebra?’

‘Father-in-law, are you even listening to yourself?’

‘He was a top-tier Archfiend. Was he really supposed to go back to school?’

Perhaps sensing his thoughts, Noah Grant, who was sitting to the side, let out a laugh. “Haha, making you learn this with no foundation would be pretty tough, I admit. But it’s fine. I’m not on Earth anymore; I’m standing at the very pinnacle of science. So if you want a shortcut, there are other ways. For instance, knowledge transfer.”

“Sit tight, bro. Let’s do this the direct way.”

As he spoke, his hands formed a series of seals, and a layer of a Barrier enveloped him. At the same time, he gently raised a hand and tapped Javier Sinclair on the forehead.

The next moment, all sorts of mathematical knowledge was forcibly crammed into his mind. Geometry, algebra, functions… and even middle school and elementary school math…

When his father-in-law pulled his hand back, he was sweating. “That’s it, I’m totally drained. Bro, give it a try. How is it?”

“I’ll try.”

With that, he closed his eyes.

All sorts of symbols flashed through his mind, arranging themselves into concepts he could understand.

‘So these are algebraic functions.’

When he opened his eyes, he gave a slight nod.

“I understand now. So that’s how it works.”

In that moment.

As he applied his new knowledge of functions and algebra to the previously unsolvable Seal, it suddenly seemed easy. He could unravel it layer by layer, just like solving a test from a teacher and getting all the answers right. By doing so, the Sealing Skill in Celeste Grant’s bloodline would be undone.

‘I have to admit, this father-in-law of mine is really something else. Speaking of which, if I had managed to replicate the Sealing Skill before… if my wife had seen it, she probably could have undone it herself. After all, Celeste Grant is from Earth; she must have studied functions and algebra.’

‘What an oversight. A complete oversight.’

‘This was the price he paid for being uneducated.’

But, having come here…

…he was still happy to have met his in-laws.
