I'm a little bit cute after transforming.

The Sword Saint snapped out of his daze and looked at Diana with a complicated expression.

"Anna, I misunderstood you just now!"

"It's alright, Master Yi, I'm used to it."

The Sword Saint patted Diana on the head.

"Anna, although you have a photographic memory and have memorized all the sword techniques, swordsmanship is not just about imitation. You need to grasp the essence of it. Come! I will spar with you using only sword techniques and teach you how to fight in real combat!"

Diana nodded and activated her Prediction and Wisdom skills, which not only allowed her to predict the Sword Saint's movements but also enabled her to quickly execute the best counterattack moves!

After only a short exchange, the Sword Saint felt the pressure and realized that he was actually at a disadvantage!

Diana not only uses all kinds of moves perfectly, but she also seems to be able to see through my movements. I am no match for her just by relying on her moves!

After enduring more than ten more moves, the Sword Saint retreated, narrowly avoiding Diana's sword strike.

"Alright! That's enough!"

The Sword Saint sheathed his sword, wiped the cold sweat from his brow, and fell into self-doubt. 'I've practiced the Limitless Sword Technique my whole life, and it's not even as effective as a child watching it once?'

Diana sheathed her sword as well. She felt that the Limitless Sword Technique was just so-so, because she hadn't gained any new skills after using it; it only added some attack methods, which wasn't as direct as casting magic.

Seeing that Diana seemed rather uninterested, the Sword Saint couldn't help but sigh.

"Anna, didn't you want to learn how to control your sword energy? Come with me!"

After the Sword Saint finished speaking, he walked into the wooden house, and Diana quickly followed.

"Master Yi, why do we need to go inside to practice sword control with qi?"

The swordsman took two prayer mats and placed them in front of the offering table. He sat cross-legged on one of them and then patted the other prayer mat next to him.

"Anna, come and sit down."

Diana plopped down on it.

The Sword Saint laughed.

"Anna, do you think this Wuji Sword Technique isn't that powerful? Just some impressive moves and routines?"

Diana scratched her head sheepishly.

"Yes, Master Yi, how did you know what I was thinking?"

The Sword Saint coughed twice, inwardly scoffing, 'How was I supposed to know? It was written all over your face!'

"In short, it's not what you imagine. Although the Limitless Sword Technique is exquisite, it still needs to be combined with another set of skills!"

Diana became interested.

"What skill!"

The Sword Saint's expression was solemn.

"This skill is the most important. Even if many geniuses have mastered the Limitless Sword Technique, they still cannot master this skill!"

"What kind of skill is this, Master Yi?!"

Diana was thoroughly exasperated by this old man; he really knew how to keep things in suspense!

Seeing Diana's anxious expression, the Sword Saint finally felt a little better and chuckled:

"This technique is actually just a breathing method!"

"Breathing technique?"

Diana felt like she'd heard that somewhere before.

The Sword Saint nodded.

"Yes! It's the breathing technique! This space contains not only various magical elements, but also something called Qi. By inhaling it through a special breathing method, one can not only greatly enhance their physical potential, but also, upon reaching a certain level, extend it out of the body through a specific route!"

As he spoke, the Sword Saint brought his index and middle fingers together, and a wisp of transparent and sharp energy, about an inch long, rose from his fingertips.

Diana gasped repeatedly and reached out to touch it.

The Sword Saint quickly stopped him and withdrew his energy.

"Anna, your anger can be very sharp. You'd better be careful in the future!"

Diana nodded, seemingly understanding.

"Alright! Anna, now I'll teach you the breathing frequency and how to extract air from the air! Remember, don't rush, or you'll easily get hurt!"

After giving repeated warnings, the Sword Saint demonstrated the techniques and explained the key points and precautions.

Diana watched the Sword Saint's breathing rate while listening carefully to his explanation. After one cycle, she understood all the steps.

Diana closed her eyes and began to breathe at a specific rhythm.

The Sword Saint looked at Diana's perfectly synchronized breathing and felt genuine admiration. He himself had taken a month to get used to this breathing method!

"Anna, try to extract air from the air. Be sure to go slowly; it might be painful at first! Hang in there!"

The Sword Saint couldn't help but feel a little worried for her. This step of extracting Qi was something that should have been attempted only after she had mastered the breathing rhythm, but Diana was just too extraordinary, and the Sword Saint inexplicably felt that she could complete it!

Diana wasn't used to breathing at this frequency at first, but after going through a cycle, she found it quite comfortable and felt that all the cells in her body were becoming active.

Upon hearing that the Sword Saint had instructed her to extract the energy from it, Diana immediately began to try.

The inhaled air begins to circulate within the body along a specific trajectory, and a distinct wisp of air is condensed from it.

Diana felt a warm sensation, without the pain the Sword Saint had described, perhaps because she possessed pain immunity.

'Ding! Proficiency achieved, skill (Qi Control Technique 1) acquired.'

Diana was overjoyed. 'The skill is here!'

Then, without hesitation, Diana maxed out the Qi Control skill!

As the brain system broadcast the message, the Qi Control skill was upgraded to level 10!

In an instant, Diana seemed to sense the omnipresent air in the air. She took a deep breath, and all that air rushed into her body, then circulated wildly.

An invisible aura suddenly appeared on Diana's body.

The swordsman, who had been watching Diana intently, took several steps back, his pupils instantly contracting.

"This...this is impossible! This is!"

As soon as he finished speaking, the ancient longsword on the altar began to tremble violently.

With a sharp clang, the longsword was drawn from its sheath on its own, hovering in the air and slowly rotating around Diana.

Diana's aura seemed to have formed a connection with the sword, and the sword's blade even shimmered with light!

The Sword Saint's voice trembled, and tears welled in his eyes.

"Use... Qi... to... control... the... sword!"

"For so many years! For so many years no one has been able to reach this level! Master! Do you see? My disciple has done it!"
