Demon Slayer: Strength Gained with Every Swing of the Sword

Epic Item in the Universal Shop: Spiritual Power Secret Technique

"Hiss... It costs 3 million sword swings?"

Feng Yu looked at his remaining balance of just over 3.8 million sword swings, deep in thought.

"At this point, I've already balanced my defense, speed, and attack. This spiritual power secret technique is like dew in a scorching desert to me... So..."

"Buy it! Opportunities like this don't come around often. If I miss it, it's gone. I still have over 800,000 sword swings left, so I'll upgrade my speed first."

"After all, the effects of the Body Strengthening Technique and Immortal Body are enough for me right now..."

With excitement, Feng Yu clicked the "Buy" button. In an instant, his sword swing balance dropped to just over 800,000.

"Back to square one..."

"I guess I'll have to work hard to earn more sword swings to make a living..."

Now, Feng Yu couldn't help but feel like picking up his big sword and slashing at the evil demons.

"Sigh... If only there were more final trials like that one, I'd be on top in no time—smashing the Twelve Kizuki, even Muzan Kibutsuji himself..."

If members of the Demon Slayer Corps heard Feng Yu's thoughts, they would probably strip him naked and hang him up for a beating.

Because of the trial, Feng Yu had killed most of the demons, but there were not enough evil demons for the trial. The final assessment had been delayed for a year, and Demon Slayer Corps members had gone out to hunt normal demons to fill the gap. But Feng Yu remained blissfully unaware of this.

Spiritual Power Secret Technique: By meditating, one can enhance their spiritual power to resist mental attacks. Once perfected, the spiritual power takes physical form, and there may be unexpected surprises.

"This is another technique just waiting to be learned, but unlike the other rare techniques, it doesn't have an upgrade suffix attached. I wonder how much I need to enhance it..."

"However, the effects seem pretty good..."

After obtaining this secret technique to enhance his spiritual power, Feng Yu felt more energized, and his mind seemed to have become a bit sharper.

"Could this be a technique to increase my IQ?"

Feng Yu thought to himself.

But Feng Yu was mistaken; this was simply a special effect brought on by the enhancement of his spiritual power.

"Training this technique will be troublesome. Right now, the only way to earn sword swings is by practicing daily. But if I focus on cultivating this technique, it might not be worth the effort. Thankfully, this spiritual technique can be improved while sleeping, so I don't need to spend extra resources on it."

"So now, the only things I need to invest in are the techniques and the power-ups for Xiao Bai and later Xiao Hei..."

"Forget it, I'll focus on increasing my own strength first. That way, I can earn sword swings faster."

Feng Yu decided not to upgrade Xiao Bai's Beast Breathing Technique for now. After all, increasing his own strength would allow him to kill stronger evil demons, resulting in bigger rewards.

With that in mind, Feng Yu immediately clicked to upgrade the Wind-Drifting Swallow Art.

"Upgrade!"

"Upgrade!"

"Upgrade to perfection!"

In an instant, Feng Yu's mind was flooded with knowledge.

"What... where am I?"

"I've turned into a swallow?"

Feng Yu stared in shock at the hundred-meter cliff below his feet, the rain pouring down relentlessly.

"No, this is a third-person perspective. But I can still feel the swallow's emotions, posture, and movements."

Suddenly, Feng Yu's body, now the swallow, dove down. The tiny body soared through the air, unaffected by the downpour, guided by the wind.

At that moment, Feng Yu understood the essence of the Wind-Drifting Swallow Art:

Ride the wind and control the power!

A while later, Feng Yu opened his eyes, leaping into the air. He was able to step on air itself, moving at a speed three times faster than before.

He looked down at the grass and trees below, realizing he wasn't using any solid support but was simply walking on the wind.

While he couldn't reach great heights or hover in mid-air, this was still pretty impressive.

Anyone unaware might think Feng Yu had developed the ability to fly!

"Good! Very good! This is truly a system product—pure quality!" Feng Yu slowly landed, admiring the effectiveness of the Wind-Drifting Swallow Art.

"Just a shame... My sword swings are running low. I only have over 100,000 left, which means I can upgrade my technique to a higher level of perfection..."

"Should I upgrade it?" Feng Yu glanced over at the system's lottery section.

"Although there's a free daily lottery, I've already used my ten free draws... Those lottery items are pretty good though, things like Healing Pills..."

"Or I could just buy regular items from the Universal Shop..."

Feng Yu was in a dilemma. His defense was already sufficient, so there was no need to upgrade his Golden Body Technique or Five Tigers Fist for now. Regular items in the Universal Shop cost at least 10,000 sword swings, and most of them were healing potions, which didn't offer much.

But the lottery was different—it had uncertainty, and who knew, he might just get lucky and win a legendary item.

"Ah, forget it, I'll go for the lottery! Ten draws! Please, give me a golden legendary item!"

Feng Yu shouted.

"Congratulations, you've won: Healing Pills x5, Stamina Pills x2, Spicy Strips x2, Detox Pills x1."

"Huh? Did I win something?"

"Stamina Pills... and Detox Pills..."

Stamina Pills: Restores physical stamina.

Detox Pills: Removes toxins.

"Wow, these names are exactly as expected—straightforward and to the point!"

"Well, not bad. I'll save them for later..." Feng Yu took out the spicy strips and began eating them.

"Mmm... Still the familiar taste."

"Xiao Bai, want some spicy strips?" Feng Yu smiled.

"Ying?"

Since Xiao Bai's awakening, its eyes had become even more intelligent.

Sensing the spicy strips in Feng Yu's hand, Xiao Bai's mouth watered instinctively.

"Ying!"

Xiao Bai snatched a strip, devouring it eagerly, then spun around joyfully, causing Feng Yu to jump in surprise.

"Wow, that was a bit much... Looks like I've conquered another creature with spicy strips."

The entire bag of spicy strips was quickly finished between Feng Yu and Xiao Bai, leaving the air still thick with their scent.

If a nearby child caught wind of it, they'd probably be drooling.

"Alright, time to earn some money..." Feng Yu stood up, grabbing his sword and began practicing again.

Every swing of his sword brought him 10 sword swings in return.

As the sun set, Feng Yu continued training in the Spiritual Power Secret Technique.

Time passed steadily, and Feng Yu's mental strength increased steadily, while Xiao Bai continued to grow stronger through the Beast Breathing Technique.

Xiao Bai understood that only by growing stronger could it help its master.

On the thirteenth day, Feng Yu's Sun Sword arrived...
