My health recovery is incredibly fast.

Beatrice raised her slender hand and pointed to the student's clothing:

"Wear it, and then we'll go to the training room to test out some wind magic. You'll then understand its uses."

Xia Zuo cast a detection spell while putting on the brooch.

..

Xia Zuo followed his mentor to the training ground.

Beatrice summoned a cloud of silver mist, roughly the weight of an adult, ten meters in front of the students.

Xia Zuo skillfully unleashed wind projectiles at the silver mist.

The wind blast, imbued with a cyan light, exploded after drifting forward ten meters, producing a crisp cracking sound.

The silver mist, which had been stationary, was pushed back about two meters by the strong airflow.

Power temporarily increased by 20 points, significantly enhancing the power of the Wind Bomb Explosion!

Xia Zuo looked at his professor and said with a sincere smile, "Thank you, Professor. I really like this brooch."

Beatrice smiled slightly, crossed her arms, and tapped her chin as she said:

"I'm glad you like it. Let's get down to business. Today I'll teach you how to properly use Tivanas's Wind Walk spell."

"This spell is unique in the history of flight spell development. It is the first wind spell that can change the caster's appearance, which is why it is classified as a high-level spell."

"When you use it, it will transform into a transparent cloud of energy. Ordinary people cannot see you, but those whose spiritual ocean has reached the level of a mage apprentice can see a very faint blue light."

"Therefore, when facing ordinary people, this Wind Walk spell is also a way to conceal one's whereabouts."

Beatrice looked at the student's excited hands-rubbing and smiled, "Don't be so impatient. This spell has quite a few drawbacks."

"Huh?" Xia Zuo blinked.

Beatrice snapped her fingers lightly.

Silver sand appeared beside her, drifting towards the open space of the training ground, where it transformed into many common things such as half-open windows, narrow door cracks, dense forests, crowded people, and sewer pipes.

"After you use this Windwalking spell, you can travel through places where your body cannot pass."

Beatrice pointed to the round opening of the drainpipe, and then to the door crack that was only half a finger's width wide.

"If you're in a sewer pipe and accidentally dissipate your gas cloud form, this is very likely to happen..."

Beatrice flicked her fingers, and a ribbon-like cloud of gas, shimmering with a blue light, floated into the drainpipe. Then, with a "bang," the ribbon-like cloud of gas exploded and transformed into a humanoid ball of light.

As the tube shattered, the humanoid ball of light itself was also reduced to a mangled mess.

"In such a confined space, your body would be crushed into a pulp. It's dangerous, isn't it?"

Xia Zuo listened to his mentor's words and nodded with difficulty.

"This Windwalking spell has more than one drawback."

Beatrice summoned a band of gas cloud once more.

The clouds drifted toward the dense forest that had been formed from the silver sand, weaving between the tree trunks.

Its direction changes due to the obstruction of trees. Sometimes it cannot change direction in time and can only split into two halves, drifting past the sides of the tree trunk before rejoining.

"See that? When you use Tivanas Windwalk, you have to avoid obstacles while you're floating, otherwise the obstacles can split you in two."

"When you are split apart, you will feel pain. And the pain will interrupt the spell, causing a series of serious consequences."

Beatrice looked at the student who had frowned, her tone somewhat grave:

"Let me put it this way. Among all high-level spells, Tivanas Windwalk is one of the more difficult to master."

"It requires very strong perception to avoid obstacles, extremely strong willpower to resist the onslaught of gales, blizzards, and scorching sun, as well as the pain of being separated by obstacles."

"If you want to experience that feeling of being split apart, I'll be there to keep watch and prevent you from having a tree trunk inside your body after you leave your magical form."

"Doing this serves as a reminder not to recklessly pass through obstacles in the form of a cloud of gas, lest it cause serious trouble."

Xia Zuo hesitated for a few seconds, then nodded heavily, "Professor, I want to give it a try."

"Alright. The method for using the talent spell is very simple. After you enter a shallow meditative state, trace the pattern of the [Floating] trait, and then silently recite the name of the spell."

Beatrice walked a few steps to the sidelines, giving the students more space to cast spells.

Xia Zuo stood still, narrowed his eyes, and calmly entered a shallow meditative state, silently reciting:

"Tivanas Wind Walk".

He felt a sudden lightness in his body, and his feet involuntarily left the ground. He could no longer breathe, blink, raise his hand, scratch his head, or perform any other actions.

Xia Zuo looked down at his own body.

The starry night robe adorned with sequins was gone. A completely transparent cloud of mist replaced her body, with a very faint blue light flowing within it.

Walking forward became floating forward horizontally, and jumping and crouching were replaced by taking off and falling.

The ribbon-like cloud that Xia Zuo transformed into hovered and drifted two or three meters high, familiar with the light and airy cloud shape.

"Professor, I'm ready."

Xia Zuo opened his mouth to speak, but found that he only exhaled a few breaths of air and could not make any sound.

Beatrice stood on the sidelines and watched as the clouds of energy the students had transformed into drifted toward the woods. She reminded them, "Try to slow down your drifting speed."

Xia Zuo, in his cloud form, circled around in response, then slowly floated to the nearest tree trunk and tried to touch it with the tail of the cloud formed from his feet.

A slight tingling sensation came from where the tail of the cloud split.

With a thought, Xia Zuo brought up his own health data.

..

[Health Points] 48/48 (Slight Poisoning)

[Base Health Regeneration Speed]

6 points/hour

[Real-time Health Regeneration Speed]

6-3 → 2 points/hour

..

Sure enough, the damage, pain, or other negative effects received while in the Qi Cloud state will affect the body.

Xia Zuo tried to make the tree trunk pass through his cloud of qi.

The real-time health regeneration rate is always positive.

He increased his drifting speed, moving at a normal walking speed—about 5 kilometers per hour—and crashed into the tree trunk.

..

[Real-time Health Regeneration Speed]

6-5 → 1 points/hour

..

The healing rate is reduced to 1 point per hour.

Xia Zuo only felt a slight tingling and numbness, far from the point of pain!

The answer is obvious!

Provided the obstacle remains stationary.

When the cloud form is divided by obstacles, the rate of health loss is equal to the drifting speed.

As long as the real-time health regeneration rate is positive, there will be no pain.

in other words.

Other mages need to avoid obstacles.

However, with the help of data-driven modifications, as long as Xia Zuo maintains a positive real-time health regeneration rate, he can move in a straight line through numerous obstacles.

Xia Zuo floated back to the ground, transformed back into human form, rubbed his temples, and asked, feigning dizziness:

"Professor, may I float to a higher place? To avoid the crowds and forests on the ground."

Beatrice shook her head, her tone growing increasingly serious:

"No. The airflow at higher altitudes is unstable. If a strong gust of wind blows, the pain you feel will be several times greater than when you are being torn apart by an obstacle."

Beatrice raised her right hand and summoned a blue, ribbon-like cloud of energy.

The cloud drifted high into the sky, about ten meters above the ground.

A strong, blue wind, as smooth as a wall, rushed towards the cloud of gas.

"Whoo~"

The originally intact band of gas cloud was violently torn apart, with some parts even being swept several meters away by the strong wind.

Just looking at it makes me feel so painful...

Xia Zuo swallowed hard…

It would probably need a health regeneration rate of 30-40 points per hour to withstand the impact of strong winds.
