Another skill is also very useful, named Bukū-jutsu.

【Skill Name: Bukū-jutsu LV1】

【Skill Description: Originating from the world of "Dragon Ball," it is a secret technique of the Crane School that allows one to fly in the air, enabling players to move freely in the air without being restricted by gravity.】

Chen Yu naturally knew about Bukū-jutsu; initially, only those from the Crane School, like Chiaotzu and Tien Shinhan, could use it.

Later, Son Goku, Krillin, and others also learned Bukū-jutsu, and after that, it became a common skill.

Almost every minion and villain in the later stages could fly.

But this doesn't affect its uniqueness; with this skill, Chen Yu can switch from ground combat to aerial combat, further enhancing his fighting capabilities.

In the original work, characters used Ki to manipulate Bukū-jutsu for flight, but in Chen Yu's hands, the magic power within his body replaced the role of Ki from the "Dragon Ball" world, allowing Chen Yu to fly off the ground as well.

After acquiring this skill, the flying skill previously obtained in flying class suddenly had an additional line of annotation added to it.

Flying Skill LV1 — flying broom Riding Version.

Used to differentiate it from the ability to fly in the air like Bukū-jutsu.

The flying skill is still somewhat different from Bukū-jutsu.

The flying skill only requires riding a flying broom to fly, and the magic consumed during flight is negligible.

But Bukū-jutsu is different; Bukū-jutsu consumes 0.1 of Chen Yu's magic power per second during flight.

With Chen Yu's current 84 magic points, he can only sustain it for 14 minutes before it's completely depleted.

If he flies at full speed, the rate of magic consumption will increase exponentially.

And perhaps because the level of Bukū-jutsu is relatively low, the normal self-flying speed is not fast, even a beat slower than flying on a flying broom.

But Chen Yu was still quite content.

This Bukū-jutsu can also be used as a trump card.

Especially when facing steep environments like cliffs and precipices, when others think you have no flying broom and no escape, a Bukū-jutsu can leave them dumbfounded.

After all, in "Harry Potter," there are truly very few wizards who can fly without the aid of tools like flying brooms.

In the book "quidditch through the ages," it states at the very beginning: "To date, wizards have not invented any spells that allow them to fly in human form without any tools."

Perhaps the book was written quite early, and at that time, no wizard had indeed invented a spell for flying without tools.

But later in the original work, Lord Voldemort and Snape did have experiences of flying without the aid of other tools.

However, it cannot be ruled out that this spell for flying without tools was invented by Lord Voldemort.

It's also possible that Snape, whom Lord Voldemort later favored, taught him his self-invented flying spell.

After all, in Lord Voldemort's eyes, Snape was always loyal to him.

Time flies quickly, and another month passed in the blink of an eye.

Since Professor McGonagall warned the Little Wizards not to go into the Forbidden Forest.

Chen Yu also stopped venturing deep into the Forbidden Forest.

Mainly, the Centaurs in the Forbidden Forest left many runes that Chen Yu couldn't understand in the forest, seemingly for warning.

Before figuring out the purpose of those runes, Chen Yu thought it was better to be cautious.

After all, if he accidentally exposed himself to the Centaurs, it would be too much of a loss.

He couldn't possibly kill all the Centaurs he saw, could he?

Centaurs don't look like villainous monsters like Acromantulas at first glance.

Centaurs at least have half a body that looks like a human, and since there's no enmity between them, fighting them would still carry some psychological burden.

It was just tough on Professor Quirrell.

Recently, Professor Quirrell's body trembled more and more during class, feeling like he was in the late stages of cancer, looking extremely listless.

Some Little Wizards even discussed whether Professor Quirrell might suddenly drop dead during a Defense Against the Dark Arts Class class and return to teach them as a ghost professor, like in History of Magic class.

Chen Yu was also somewhat curious, wondering if Professor Quirrell could still obtain Unicorn blood under the circumstances where Hogwarts professors were constantly monitoring the Forbidden Forest and Centaurs were on high alert.

But these things had nothing to do with Chen Yu; currently, Chen Yu just hoped to spend each day peacefully, learning new spells while watching his skill proficiency increase day by day.

It was also a coincidence; if he hadn't used a random item card to open a 【Wanderer's Experience Book】, his Killing Curse wouldn't have directly risen to level three.

【Wanderer's Experience Book】

【Description: This is a Wanderer's Experience Book from "Teyvat," containing 1000 experience points. If one does not live in the Seven Nations of the continent, these experiences are still necessary.】

Chen Yu's system didn't have level-up experience, only skill experience, so these one thousand experience points were naturally added to the Avada Kedavra skill.

This was also the only spell among Chen Yu's many spells that reached LV3.

At LV3, Chen Yu found that he gained three new variations in controlling Avada Kedavra.

First, he could guide the ordinary Avada Kedavra beam to curve.

Second, he could split the Avada Kedavra beam into multiple rays, currently up to seven rays.

Third, he could quickly charge Avada Kedavra, investing more magic power to make the Avada Kedavra ray ejected from his wand resemble a light cannon.

Guidance, splitting, and convergence—these were the changes after Chen Yu upgraded the spell to LV3.

Of course, as Chen Yu expected, the Killing Curse at LV4 required 10,000 experience points.

He remembered that the 【Hero's Experience Book】 contained 20,000 experience points, and Chen Yu had secretly prayed for a purple book next time he got an experience book.

However, the results of the subsequent draws were not very satisfactory.

It was as if all his luck had been used up in the previous draws.

The remaining three items were 【Sunset Fruit】, 【Apple】, and 【Delicious Teyvat Fried Egg】.

The 【Sunset Fruit】, 【Apple】, and 【Teyvat Fried Egg】 were all foods from Teyvat.

Among them, 【Sunset Fruit】 and 【Apple】 could restore 300 player health points after consumption.

Although his broken panel didn't show how many health points the player currently had, they should also be usable as red potions.

Chen Yu was a bit confused about the 【Delicious Teyvat Fried Egg】.

【Delicious Teyvat Fried Egg】

【Description: This is a single-sided fried poultry egg from "Teyvat," with a warm, sunny taste. Just one bite brings a surge of immense vitality. It can revive the consumed character, restoring 150 health points.】

The description was very clear: like the 【Sunset Fruit】 and 【Apple】, it needed to be eaten to take effect.

The problem was that dead people can't eat.

To use it on himself, would he have to stuff the fried egg into his mouth just before dying?

And at the moment of falling, let inertia cause his upper and lower jaws to collide, biting the fried egg in his mouth, so that it could have the intended effect?

This trigger condition was too harsh, wasn't it?

Or perhaps this item was actually for others.

After someone died, he would use the fried egg to stuff their mouth, then close their jaw, make them perform a chewing motion, and then the person would revive.

As soon as he thought of this, Chen Yu felt like cursing.

He finally drew a resurrection item, but the trigger condition for himself was too harsh, and he was unwilling to use it on others.

This was a second life; how could he bear to use it on others when he hadn't even had the benefit of resurrection himself?

Chen Yu felt that his luck this month had been bad recently, so he exchanged the remaining two draws for random skill cards.

The result was one Art of Food Creation and one Water-Making Spell.

【Art of Food Creation】

【Skill Description: A magic from "World of Warcraft," players can use magic power to synthesize two magical dark breads for players and allies to eat and satiate hunger, capable of replenishing a small amount of their vitality. These foods will disappear one day after being created by the player.】

【Water-Making Spell】

【Skill Description: A magic from "World of Warcraft," players can use magic power to synthesize 2 bottles of magical glacial water for players and allies to drink, capable of replenishing a small amount of their magic points. These waters will disappear one day after being created by the player.】

These two skills are divine skills for survival in uninhabited areas or deserts, but for Chen Yu, who currently lives in Hogwarts Castle and eats lavish meals every day, they are useless.

Flavorless to eat, yet a pity to discard.
