Demon Slayer: Strength Gained with Every Swing of the Sword

In the following days, Feng Yu continued his regular practice of swinging his sword, while also asking Sakonji Urokodaki where he could learn martial arts.

However, Feng Yu was disappointed when Urokodaki told him that he hadn't encountered any significant martial arts dojos, only a few lesser ones.

This world was rapidly advancing, with firearms and ammunition increasing in number, and the era of hand-to-hand combat was long past.

The only kind of dojo still common was for sword training.

Yet, Feng Yu felt that his swordsmanship had already reached a high level. Continuing to learn other styles seemed unlikely to improve his abilities much.

He could only wait until the system upgraded to see what the Universal Shop had in store.

On the eighth day after Feng Yu returned to Sagiri Mountain, the system upgrade notification finally sounded.

Ding! System upgrade complete. The first-tier Universal Shop is now open. Please check it out.

"Since this is the host's first time opening the system, the reward includes 10 rare or higher-quality items."

During these few days, Feng Yu diligently practiced swinging his sword, collecting numerous sword swings.

The Final Trial quest also displayed as completed, so Feng Yu received the quest reward.

His sword swings instantly reached over 5.3 million, and a golden Beast Breathing Technique appeared in the system's bag space.

So this is the Beast Breathing Technique... Xiao Bai... I didn't expect it to be this simple to use...

"Xiao Bai, come here."

Feng Yu called Xiao Bai over, then took the Beast Breathing Technique and gently pressed it against Xiao Bai's forehead, allowing it to slowly integrate into Xiao Bai's mind.

Xiao Bai stood stunned, watching as Feng Yu placed his hand on its head. Then, an overwhelming flood of knowledge surged into its brain.

Feng Yu felt Xiao Bai's breathing change instantly, as a rhythm of breathing, similar to that of humans, appeared around Xiao Bai. Yet, it was different from human breathing techniques.

"Impressive, my Xiao Bai... You mastered it on the first try."

Seeing Xiao Bai successfully master the Beast Breathing Technique, Feng Yu smiled with satisfaction. After all, there was a prerequisite for this technique: it could only be used three times, and after those three uses, it would become ineffective, whether or not mastery was achieved.

"Now, the next step is Xiao Hei... But I have no idea where it's run off to now…"

"Having no contract really is troublesome…"

Feng Yu thought to himself.

Ding! Congratulations! Your pet, the White Fox, has successfully awakened. Please check its attributes.

"Huh? Xiao Bai's attributes are now separated?"

Feng Yu quickly checked Xiao Bai's status.

Name: Xiao Bai

Species: White Fox

Divinity Value: 0.00000001

Owner: Feng Yu

Skills: Beast Breathing Technique (Beginner, can be upgraded)

Awakening: Telekinesis, Charm, Shape-shifting Control

Description: This was originally just an ordinary white fox, but it has gained a trace of divinity.

"Impressive, Xiao Bai is truly extraordinary. Not only has it awakened telekinesis and charm, but it also gained the ability to control its shape. That means I can take Xiao Bai on missions now."

"I wonder if Xiao Hei also has shape-shifting control once it awakens…"

"If so... would that mean I have both land and air mounts? Imagine how awesome that would be…"

Feng Yu began fantasizing about riding Xiao Bai on the ground and Xiao Hei in the sky.

After all, every man's dream is to fly once, right?

"But Xiao Bai can also 'pay to strengthen'... but I, as the owner, would have to spend money... This is such a scam…"

"Looks like I'll have to work hard and make money to support the family in the future…"

Thinking about how, after contracting Xiao Hei, he would have two pets to feed, Feng Yu felt a headache.

"Maybe I should try spending money to strengthen Xiao Bai..."

"No, no, let's first check the Universal Shop. What if I buy something for Xiao Bai and then run out of money for the things I really need?"

Feng Yu opened the Universal Shop.

The shop was like a small online store from his previous life, with only 30 stalls. The ten rare or higher-quality items were placed at the front.

"Only one epic item, and the rest are all rare... This is a rip-off..."

"But there are a few items that I need right now…"

"This one will do, 500,000 sword swings isn't too bad…"

After purchasing, a large amount of knowledge instantly flooded Feng Yu's mind.

Body Techniques: Wind-Drifting Swallow Art… Nice, very nice. This will help make up for my lack of speed.

Wind-Drifting Swallow Art: When perfected, the user's speed becomes as fast as a swallow, able to walk on the wind.

"This Golden Body Technique is also great. When perfected, a golden film forms on the body, making it invulnerable to Swords and bullets, increasing my defense. I'll buy this too!"

"This Five Tigers Fist is good as well. When perfected, an internal energy forms in the body, protecting the meridians. A single punch can match the strength of five tigers."

These rare techniques only cost 500,000 sword swings each, but once bought, they required more sword swings to improve or could be trained manually.

But Feng Yu thought, What sane person would train? Paying money to upgrade is way more efficient...

The rare techniques he bought cost a total of 1.5 million sword swings, and he had already entered the basics. Each skill showed a "can be upgraded" prompt.

Looking at the remaining 3.8 million sword swings on his panel…

His gaze shifted to the lone epic item...
