Demon Slayer Basic Breathing Technique: Strengthen cardiopulmonary function, allowing the blood to absorb a large amount of oxygen in a short period of time, which can greatly increase physical ability in an instant, and temporarily possess physical fitness comparable to that of a ghost.

Breathing Method: Tiger and Leopard Thunder Sound: The breathing rhythm of a specific frequency vibrates the qi and blood, exercising the internal organs, and even the muscles and bones.Practicing to the extreme can make a person completely reborn, and his physical ability can reach the limit of the human body.

"Demon Slayer: Kimetsu no Yaiba... the other one should be from the world of martial arts, right?"

Xia Hua didn't know much about Chinese martial arts, most of it was hearsay.

On the contrary, it is the breathing method of Demon Slayer: Kimetsu no Yaiba, because of the excellent animation production and the crazy bombardment of short videos at that time.

The original breathing method of Demon Slayer World comes from Sun Breathing by Jiguo Enichi, and its five branch breathing methods of water, fire, thunder, rock, and wind are also taught by Jiguoyi Enichi himself after improving them based on his personal physique.

In addition, other branch schools with personal characteristics have evolved from the five major breathing methods.

People who practice breathing techniques have the power to temporarily compete with ghosts.

For example, cutting off rocks and trees with a sharp blade, chasing a carriage, or jumping between trees are all things that ordinary members of the Demon Slayer Corps can do.

And if you can learn one or two secret techniques in the school, you will have the strength to kill ordinary ghosts.

"How to choose? Since the system can break through the limits of skills, no matter what choice you make, there should be no bottlenecks."

Think about the various schools of Demon Slayer's basic breathing techniques, as well as techniques like Changzhong in the complete set, and the inhumanly powerful stripes...

But remember in the setting, people with stripes turned on will not live past the age of 25 except for Ji Guoyuan?

So...it's decided!

Although Demon Slayer's breathing method can make people stronger in a short time, Xia Hua knows that the only way to be strong is to be strong yourself.

Choose the branch, Breathing Method·Tiger Leopard Thunder Sound!

In an instant, the thoughts about Tiger, Leopard and Thunder merged into Xia Hua's mind.

It was as if he had practiced this breathing method thousands of times, and it was deeply engraved in his memory, like an instinct.

Xia Hua couldn't wait to calm down and try the effect of this breathing method.

He closed his eyes and his breathing became long and strange.

Gradually, dull sounds came from his body.

Xia Hua seemed to hear the sound of tsunami-like waves in his ears as his energy and blood vibrated.

This experience lasted for more than ten minutes before Xia Hua reluctantly quit the cultivation state.

"The body...has become stronger."

After just ten minutes of practice, Xia Hua felt slight changes in his body.

This improvement may be insignificant, but compared to the lack of improvement in physical training, it has undoubtedly opened up the path for Xia Hua to become stronger.

Xia Hua directly increased the level [-] tiger leiyin to level [-] in one breath.

Levels 160 to [-] add [-] points each time, and level [-] adds [-] points, for a total of [-] points, plus the [-] points consumed for breakthrough.

Xia Hua has a total of 250 points, but now only 41 points are left.

It would take forty points to continue to strengthen Tiger Pao Leiyin, so he did not continue to strengthen it, but kept the points for emergencies.

After adding the points, Xia Hua felt refreshed.

He took out his sunglasses from his pocket, put the baseball cap on his head, and transformed into an ordinary Oriental.

But as an undercover agent, you need to be cautious.

Xia Hua first drove around, then took a taxi from the street to the nearest bus, and finally took a three-hour bus ride to New York.

After arriving in New York, the first thing to do is to contact the members of the organization.

The organization's safe house is a private warehouse in Brooklyn.

This place doesn't seem big, just a few neat rows of simple houses.

There is nothing special in the warehouse. There is a scrapped car with its wheels removed in the center and a wall full of equipment and tools. It is no different from an ordinary garage.

In fact, there is another layer of space underground here.

Xia Hua opened the warehouse gate and walked in, then closed the gate again.

Then he got into the car, and through the mechanism in the car, he took the chair and sank into the ground.

As soon as he entered the underground space, Xia Hua smelled a strange smell.

"Oh my god, how long have you been out since? Isn't it already sour?"

This underground space is like a secret agent safe house in a movie.

A large screen, an unfamiliar tool table, and various weapons and props are all available.

"It's been...about a month, right?"

The one making the sound was a group of humanoid creatures huddled on a chair.

The messy long hair was draped over her body like kelp, almost submerging her petite body.

This is a girl, but Xia Hua has never regarded her as a woman.

Because he has never seen such a nerdy creature in his life.

"I need the qualifications to enter Osborne Tower. Do you have any good suggestions? Hongke?"

Hongke is the code name of the girl. She is a computer super talent who is responsible for organizing network security issues in New York and providing relevant assistance.

"Osborne invites outstanding students from various universities in New York to visit the company every weekend. I can help you fake your identity."

Hongke curled up in her chair, tapping her fingers on the keyboard, and soon hacked into Osborn Industries' network system and added Xia Hua's fake identity to the visiting list.

Immediately afterwards, the 3D printer nearby printed out the relevant ID documents and Osborne's pass.

"Thanks."

Xia Hua took out his ID card, and the acrylic card showed a picture that looked like his.

The matter of forging identities is nothing more than familiar to undercover agents, and they have been filed for a long time.

"Ten o'clock the day after tomorrow, Osborne Tower."

Hongke opened his dead eyes and breathed out half-deadly.

She reached out to grab the Fatty Happy Water on the table, but Xia Hua intercepted her.

"Gulu gulu...burp..."

After taking a big sip, Xia Hua felt full and stuffed the bottle back into Hongke's hand with satisfaction.

"Go take a shower and change clothes. You smell greasy."

After complaining, Xia Hua left the safe house unsteadily.

Hongke, who was curled up in a chair and seemed to be in a daze, completely collapsed after the person left.

She moved her hands lightly and let the soda in her hands fall to the floor.

"Indirect kissing...is forbidden..."

Under the messy bangs, Hongke's cheeks were hot and he murmured to himself.

Because she raised her head, she was able to reveal her true appearance.

Her facial features are exquisite, her skin is fair, and her pores are almost invisible.

I have to admit that no matter how sloppy this talented girl is, she still has a sweet face.
