Louis stared blankly at the first line of the letter, momentarily at a loss for words.

"Oh, Cialdini, so you were waiting for me here!"

He hadn't looked at the following content yet, but he knew the letter left by the big guy contained quite a lot.

It's not important. There's no need to be so cautious, using the magic blade to seal it and having Vier deliver it to him later.

And... what do you mean by "just a mere Celestial Blade"?

How would others feel if they heard this?

Is it really professional criticism?

But it doesn't matter, as it hardly affects him.

Because he had already learned the Celestial Blade.

He was curious about what the Sword Master specifically wanted to tell him, needing such caution to leave a letter.

He continued reading.

"I already noticed something was wrong the first time I killed Sin of Envy. The use of extraordinary powers follows certain rules; it's always an equivalent exchange, not something from nothing."

"For Sin of Envy to revive so frequently, there must be a significant price to pay. After killing him twice, I could determine he had at least two fatal weaknesses."

"After the first kill, there were still very obvious traits of the Giant Race in his body. I've heard that the King of Fury has a congenital weakness, making him much weaker than a normal giant, so it's safe to say this physique wasn't from the King of Fury."

"It's highly likely he used some means, like disguising as a giant, to gain the King of Fury's trust. I even suspect his revival method is akin to parasitism, possibly a soul-based authority."

Goodness!

Louis was shocked upon reading this.

Is this what it means to be a prodigy?

Such a keen combat intuition.

The Lokeshi Empire's thirteen families expended great effort to confirm the information, yet he sensed the enemy's methods in a brief skirmish.

He strongly suspected that if it weren't for the guy using authority to directly copy the Sword Master's techniques, even if he could revive, Cialdini would have found a loophole to kill again.

His finger skimmed the letter as Cialdini continued with more shocking words.

"After the second kill, he stole my path, but I could feel the giant's traits in him had significantly weakened."

"The powerful healing abilities and strength of a giant became less evident on him, leaving basically two possibilities."

"First, he seizes others' power, which isn't permanent, but gradually diminishes according to consumption."

"Second, his body isn't sufficient to accommodate multiple functional powers simultaneously, so he must selectivity house part of it."

"In either case, if it were you, you'd find a way, right?"

"Lastly, if you're intent on killing Sin of Envy, I don't recommend heavily relying on the Lokeshi's power. The third generation Envy hails from the Extreme Cold Giant Elephant Family, the only son of His Majesty Tal Griffin."

"That's all I have to say. I believe the Path of the Celestial Blade won't end with my generation."

Louis flipped to the end of the letter, letting out a long sigh.

"Oh Cialdini, you're really giving me a challenge."

He finally understood why Cialdini was so cautious.

This guy wasn't just a true combat genius; he was also quite a sharp individual.

Even though he didn't elaborate in the letter, he likely guessed the truth behind Sin of Envy's easy revival.

Even if Sin of Envy is a soul chimera, part of the chimera's material would have to be from the original host, right?

The Sword Master left the choice to him.

If the Ense Empire leads the attack on Sin of Envy, then everyone's goals align, with less interference.

But if they rely on the Lokeshi Empire's power...

Frankly, Louis doesn't believe Emperor Tal Griffin of Lokeshi has no thoughts, without considering the chance to awaken the Emperor's son's consciousness within Sin of Envy.

If such thoughts arise and there's direct interference, Sin of Envy's smooth demise becomes a mystery.

Even if Tal Griffin doesn't interfere personally, who's to say no one might think of protecting Sin of Envy to gain favor with the Emperor?

Don't think it's impossible.

Reality is more fantastical than fiction.

Given that, Louis might as well handle it himself.

"Looks like dealing with Sin of Envy requires more of my effort."

He felt a bit irritated.

Recently there's been too much for him to handle by himself.

However...

He glanced at the still-glimmering crystal of the Celestial Blade Path amidst the Tomb of Soldiers.

If he uses this, the likelihood of killing Sin of Envy remains great.

He cannot afford to delay further.

Action must be taken swiftly.

Even at his last moment of defeat, though Sin of Envy overpowered him, Cialdini still seized the time to identify his own flaw.

This condensed the martial arts essence of his lifetime, under normal circumstances, no one could drive it to approach the Sword Master's level.

Except Louis.

So Cialdini intends to allow Louis a chance, contributing his final strength to killing Sin of Envy.

And what he needs—

"If I'm not mistaken, you must have told your daughter to see if I was teaching her seriously before handing it over to me, right?"

Even the Sword Master didn't expect Louis to take it too seriously.

Even if he puts on a show for a few days, genuinely teaching Vier, she would directly bring the item over to him.
