[Ding! Mastered Air Cannon Ninjutsu Version. Knowledge reinforcement in progress...]

This was the system prompt that echoed in Gu Qi's mind after he completed the Ninjutsu Version of the Air Cannon.

The principle behind the Air Cannon was essentially to compress gas and then release it instantly.

However, it took Gu Qi several months to achieve this seemingly simple principle.

The biggest problem was how to ensure the compressed air mass maintained its power after being released.

Otherwise, the Air Cannon would rapidly weaken and lose its effectiveness once fired.

To solve this, Gu Qi had a sudden inspiration and thought of a Tornado.

If the weakening couldn't be prevented, why not allow the Air Cannon to continue accumulating power during flight?

By having the fired air bullet rotate and absorb surrounding air to compress it, the loss could be offset.

Although he had an idea, implementing it was far from simple.

This was because the air bullet needed to reach a certain rotational speed to meet Gu Qi's requirements.

Unlike the Rasengan, which rotated simultaneously left and right to create tearing force, Gu Qi needed the air bullet to rotate in one direction to generate a powerful suction.

Furthermore, rotating in one direction also had the advantage of increasing the air bullet's penetration.

As for whether the direction of rotation was counter-clockwise or clockwise, one only needed to refer to how an impact drill works to bore holes.

Even with sufficient theory, the actual implementation was still very troublesome.

Fortunately, with his experience cultivating the Rasengan and his strong knowledge of mathematics and physics, Gu Qi eventually succeeded in completing this ninjutsu.

The air bullet fired by Gu Qi resembled an inverted Tornado, with a cone-shaped tip and a flared tail.

This design served two purposes: to increase lethality and to facilitate the absorption of surrounding air.

Although the process was somewhat convoluted, Gu Qi ultimately succeeded.

Gu Qi had now completed tasks 4, 5, and 6. The only remaining conditions to unlock the next stage of tasks were tasks 1, 2, and 3, which required significant time and money.

In reality, if Gu Qi had enough money, he could complete tasks 1, 2, and 3 in no time.

Unfortunately, Gu Qi didn't have that much money on hand right now.

With no other options, Gu Qi could only wait patiently.

"Hey, what's this Scroll for?" Gu Qi asked, puzzled as he took the reward from the system.

He was annoyed because he couldn't open the Scroll at all.

[Please carefully read the instruction manual.]

The system dropped this sentence and vanished without a trace.

"Tch!"

With the system being so difficult, Gu Qi had no choice but to read the manual himself.

After carefully examining the instruction manual, Gu Qi discovered that the Scroll couldn't be opened because it hadn't been unsealed yet.

To unseal it, he had to complete the trial mission issued by the Scroll.

However, the manual didn't explain what the Scroll was used for.

"Whatever, let's see what the trial is first!"

Gu Qi shrugged and, following the instructions, used a kunai to cut his finger, dripping blood onto the Scroll.

A swirl of smoke later, the character "Refine" appeared on the Scroll.

At the same time, the system's prompt sounded in Gu Qi's mind.

[Ding! Do you wish to activate the Trial Space? 1000 Ryo/time.]

"..." Gu Qi was speechless. This was truly characteristic of the system.

Although he was reluctant, Gu Qi had no choice but to grudgingly pay the price.

[Trial Space activating... 3, 2, 1]

As the countdown hit zero, Gu Qi's figure abruptly vanished from the room.

The moment Gu Qi regained his senses, he found himself in a dojo with a distinct martial arts style.

"Greetings, challenger. Please prepare yourself, the challenge is about to begin."

Before Gu Qi could finish observing his surroundings, he heard a hearty voice from across from him.

Following the sound, Gu Qi saw a person wearing beige shorts with a few patches, white leg wraps, straw sandals, a bare upper body, a fair and plump belly, and large dark circles under their eyes.

"You are..." Gu Qi pointed at the person in surprise. He was far too familiar with this appearance.

"That's right, I am your opponent. So, please attack!"

Gu Qi froze, flustered. "Whoa, whoa, whoa, did something get messed up!"

Gu Qi was absolutely no match for fighting this person!

You have to understand that the guy in front of me is a 1.88-meter-tall, over 100-kilogram super-fatty.

Then look at Gu Qi's skinny arms and legs; they're not even in the same weight class.

Forget fighting, just one "Mount Tai crush" from the opponent could take half of Gu Qi's life.

"Since you're not attacking, I'll go first." After saying that, the opponent charged straight at Gu Qi.

Watching the opponent's massive body charge at him like a tank, Gu Qi knew he had no choice but to fight.

"Konoha Whirlwind." Using the momentum of his charge, Gu Qi used his left foot as a pivot and delivered a heavy whip kick to the opponent's stomach.

Thud~

Gu Qi felt like he kicked a ball of cotton; there was no sensation of hitting a human body at all.

"Nice power, but not enough." The opponent's stomach stiffened, and Gu Qi felt a powerful force push him back.

He landed with a backflip, stabilizing himself, and charged at the opponent again.

However, since he knew he couldn't win a head-on confrontation, Gu Qi decided to use a softer approach this time.

So, Gu Qi used his incredible speed to get behind the opponent, then jumped up for a downward chop.

Yet, the back of the opponent's head seemed to have eyes; he easily raised his hands to block Gu Qi's legs.

Then, the opponent executed a backflip and, while still holding Gu Qi's leg, threw him away.

Gu Qi was a bit frustrated. He was a big fatty, yet he was so agile. Was that fair considering all the delicious food he'd eaten over the years?

Despite his thoughts, Gu Qi wasn't one to give up easily. Just as he was about to crash into the wall, he flipped and landed steadily on the wall.

"Cool, how can you do that?" Seemingly captivated by Gu Qi's skills, the opponent asked curiously.

"Want to know? ... Not telling you!" Gu Qi pushed off with his back foot and charged at the opponent again.

In mid-air, Gu Qi's left hand continuously gathered Chakra. Soon, a small Rasengan was formed.

"Rasengan!"

"Looks amazing, but I can do that too!"

Gu Qi, flying in mid-air, was surprised to see the opponent's hands begin to glow.

Then, the opponent gathered a ball of energy in his hands and forcefully pushed it towards Gu Qi.

"Whoa!" Unable to dodge in mid-air, Gu Qi quickly dispersed his Chakra and brought up his shield.

He didn't expect this ball of energy, which looked soft and weak, to exert such a powerful force upon contact with his shield.

As a result, Gu Qi, still in mid-air, was directly slammed back into the wall.

"Ouch, ouch, ouch!" Gu Qi gritted his teeth and cried out, trying to elicit sympathy from the opponent.

Unfortunately, the opponent was unmoved and relentlessly pressed his attack.

"This is troublesome."

Gu Qi stood up, silently took out a coin from his body, and simultaneously, the Lightning began to flicker around his arm.

Sizzle~

The accelerated coin flew directly towards the opponent.

Just as Gu Qi thought victory was within his grasp, the opponent suddenly grinned and used a standard Tai Chi move, "four ounces deflect a thousand pounds," to bounce the coin back.

Gu Qi then remembered that this opponent was a divine being who could even catch Shells fired from a cannon.

"Ahhh, I'm gonna die!" Gu Qi's hair stood on end. He raised shields with both hands to block the coin.

Before Gu Qi could recover, the opponent, shouting and grinning, charged at him.

"Hah!"

Then, a plump fist lightly landed on Gu Qi's cheek.
