Aizen Iori: What era is it, and why are you still using traditional cheat codes?

Haven't you seen that some people can gain the strength to kill any enemy with one punch after three years of training;

some people can learn Bankai in just a few days, from a layman to a captain-level reaper;

some people are taught by famous teachers, and they can learn to be entangled and awaken the fruit with a few sticks;

reincarnation, rebirth, time travel, plot killing, setting invincibility, the author's own son, the author's own father... There are so many

of them, like crucian carp crossing the river. But Aizen Iori knows that ordinary cheats can no longer survive in the industry with serious internal circulation, and we have to use the biggest cheats!

So what is the strongest power system common to all the heavens and the worlds?

Is it love?

Is it hatred?

Is it instinct?

Is it E=mc^2?

No, it's the style of painting!

I'm not targeting a certain person, I'm saying that everyone here, no matter what cheats you use, my Aizen Iori's style of painting is always superior to you!

This noodle is so delicious! Nangong Shuoyue exclaimed, and then a ding echoed in the boy's mind. The belated cheat code had arrived. A chat group for all realms? The group owner is the collective will of the heavens and all realms? You can become stronger by spending money? Interesting... The boss pretending to be a newbie smiled happily.

Traveling through Tokyo in the 1980s, living in Beika-cho, next door to the Cat's Eye Cafe.

I was looking forward to meeting my favorite two-dimensional character, but the system was activated and I was teleported to the Saint Seiya world on the spot.

The daily life of the anime has become a journey through the heavens, and facing the seriously injured and unconscious Ophiuchus Silver Saint Shaina, as long as you complete the interaction, you can punch in and get rewards?

So should I choose to save her?

Or take off her mask and see the girl's beauty?

Or... ignore her and return to the main plane world safely?

Lin En said-

except for the last one, I want all the rest!

Vitelli: "No, what's the point of this? Is this still China? What? Is this Planet Vegeta?"

Vegeta: "Vetli, you dog! Did you lie to me when you said your combat power was less than 10,000?!"

Son Goku: "Is this a Super Saiyan? Vitelli is so strong? I'm fired up!"

Bulma: "Ahhh!!! This is the Prince Charming of my dreams!"

No. 18: "Hmph! Don't think that just because you saved me, you can treat me... Don't... Don't do it here..."

Levi, a college student who was unemployed right after graduation, was inexplicably brought to the world of Dragon Ball by fate and became a member of the fighting nation Saiyan.

He, who was defined as a superior warrior at birth, said that Kakarot could become a Super Saiyan with a combat power of over 100 million through hard work from a combat power of 2 points. Then, Vitelli's starting point now is 1,000 times that of Kakarot!

As long as I work hard and train hard, as long as I'm strong enough, what does Frieza matter? What does Cell matter? And the God of Destruction, Binus, I've been annoyed with you for a long time!

From today on, be a person who practices diligently, facing the gravity room, and watching the spring flowers bloom!

Wait, No. 18, Bulma, what are you two doing? Don't come over here! Two against one is cheating!

Even someone as strong as a Super Saiyan would be scared when faced with such a situation~~~

Wayne split into pieces and traveled through countless worlds, but he could share power and memories in different worlds. However...

Wayne: Why are you all so abstract!

————————————

Naruto Wayne: My father is the second generation! The world is under my control, and I will do it now. Who dares to disobey? Hmm? You are not conducive to harmony, right? Come on! Cook him for me!

Wayne the Weasel: Brother, you smell so good——

Celebi Wayne: Should we throw the sleeping Kyogre into the lava today? Or take Mewtwo to find out about Mew? Hey, I have a plan. How about we go steal some snacks from Ray Karakura?

French strategist Wayne: Han and traitors cannot coexist! Since I've been reborn into the Three Kingdoms, I must unify the Central Plains and conquer the world! Wait... what did you say? Without a moment's mourning for Wuzhangyuan, the next person to arrive on the battlefield is Zhuge Liang in his most powerful form—hindsight?

Then why should I bother with the knitting? I’ll just give up and be done with it!

The same thing about simultaneous time travel: while other schools only need to diligently cultivate, rise from the ashes, face death head-on, experience adventures, and endure countless battles, Wayne, who simultaneously traveled through time, has much more to consider, considering his shared talents and strengths. ...
