simultaneous crossing in many anime worlds

Saitama seemed to have discovered a new continent, and Genos's eyes also lit up.

The two looked at each other and asked in unison, "What is Ninjutsu?"

Sonic originally didn't want to bother with them, but he couldn't resist Saitama's enthusiasm.

Seeing how interested they were, Sonic felt a bit proud, and his attitude improved significantly.

After a dry cough, Sonic began to introduce Ninjutsu.

"Just form hand signs and you can release Ninjutsu?"

"Rat – Ox – Dog – Horse – Monkey – Boar – Tiger, this hand sign is so complicated!"

"It also requires Chakra? What is Chakra?"

"Body energy? Spiritual energy? Meridian system?"

A large number of incomprehensible terms spewed out of Sonic's mouth, like a dazzling display, leaving Saitama completely confused.

Genos also didn't understand, but he listened very carefully. If he had the chance later, he would ask Dr. Kuseno for clarification.

Rumble!!!

The ground suddenly trembled, interrupting Sonic, who was in the middle of an enthusiastic speech. His expression stiffened, and he was very angry.

Saitama was also not too pleased.

"A massive energy is approaching us from underground."

Genos's life-sensing system reacted strongly.

Hearing this, Sonic and Saitama simultaneously stared at the ground.

"Despicable humans, return the surface to us!"

"Submit at the feet of the Underground King!"

A tall, muscular figure burst out of the ground, letting out a rampant laugh.

"When people are having a good chat, don't come out and cause trouble! You bastard!"

With that, Saitama punched a large hole through the Underground King's chest.

The laughter abruptly stopped.

The Underground King looked down at the fatal wound on his chest in disbelief.

Then, he slowly fell.

His eyes were filled with unwillingness…

Sonic stared at the Underground King's corpse, his eyes flickering.

The good news was that the Underground King had been taken care of, and the corpse was relatively intact, much more valuable for research than the Earthlings. His master would definitely be very happy.

The bad news was that the Underground King was taken care of by Saitama…

"Damn it, why does this bald guy always steal my kills…"

What to do?

Should I forcefully take it?

Sonic was in a fierce internal struggle. Before he left, Chu Yang had specifically warned him not to get into conflicts with Saitama again.

It seems he can't win…

Sonic recalled the punch Saitama used to instantly take care of the Underground King; he wasn't sure if he could even take it.

"Do you really want it?" Saitama pointed at the Underground King's corpse and asked curiously, "You've been staring at that weirdo's corpse since just now. Do you really want this thing?"

"Let me tell you first, this kind of weirdo can't be eaten."

Sonic was greatly alarmed, "Could it be that you've eaten other types of weirdo before?"

Saitama said with a reminiscent expression, "Seaweed, celery, mushrooms, they all tasted pretty good. Back when I was short on cash, these weirdo always appeared at just the right time."

Listening to Saitama talk about how delicious plant-type weirdo were, Sonic actually felt his appetite stir and fell silent.

Genos clenched his fist and said solemnly, "Teacher, don't worry, I won't let you go hungry again!"

Saitama nodded, touched.

"I'm too lazy to bother with you guys. Since you don't want it, I'll take the weirdo's corpse."

Sonic was about to take the Underground King's corpse but was stopped by Genos.

"Without the corpse, how can we prove that Teacher defeated the Underground King? Teacher's hero ranking at the Hero Association won't be able to rise."

Genos stood sternly in front of Sonic.

Sonic turned to Saitama and asked, "Why would a man as strong as you care about these things?"

"Whether it's S-Class or C-Class, they are all meaningless labels."

"Does being admired by others make you so intoxicated?"

Saitama pouted, "When others call you 'Flashing Ninja,' weren't you grinning from ear to ear?"

Sonic's face flushed. He hadn't realized it before, but after he truly became a hero, he did feel a secret pleasure when people called him by his title.

His verbal attack failed, so Sonic gave up on entanglement with Saitama. With this effort, he might as well go hunt other weirdo.

"It's just a weirdo that's not even Dragon-Level. Take it if you want it. I'm warning you, if you steal my prey again next time, it won't be this easy to let you leave."

Sonic snorted and prepared to leave.

"Hey, wait!"

"You can take this weirdo's corpse."

Saitama suddenly spoke.

Sonic looked at him in surprise.

Saitama scratched his head and said, "With your strength, even if I hadn't intervened, you could have easily defeated the Underground King. From the result, it really does seem like I stole your credit."

Genos also silently stepped aside. Since Teacher had said so, there was no need for him to be aggressive anymore.

"You're not a bad person."

Sonic's mouth curved upwards, and he quickly walked to the Underground King's corpse, lifting it onto his slender frame.

Saitama looked at Sonic's departing back and said with a sense of loss, "It's a pity that the conditions for learning Ninjutsu are too strict. I really wanted to learn how to breathe fire."

Genos reminded him, "Teacher, if you become a cyborg, you can also breathe fire. Dr. Kuseno will definitely help you."

"Genos, that's not what I meant." Saitama quickly waved his hand, afraid that Genos would keep pressing the topic, and left the park without looking back.

Neither Sonic, nor Saitama and Genos, noticed that there was a car parked in the corner of the park.

A lazy voice suddenly came from the back seat of the car.

"When did the Hero Association get a few heroes this strong? They look pretty good…"

The car window slowly rolled down, revealing half of a remarkably beautiful face.

The very beautiful woman first looked in the direction Saitama and the others had left, hesitated for a moment, and then told the driver to follow Sonic.

The sky gradually darkened.

Sonic walked through the forest by Gekko, unaware that someone was following him. His mind was completely occupied with how his master would praise him later.

The more he thought about it, the happier he became. Maybe he could even learn a few more powerful Ninjutsu!

Sonic returned to the House of Evolution. The woman's figure stopped outside the building. She felt inexplicably uneasy, looking at the dark building as if it were a monster waiting to devour people.

Reason told her she should turn back.

But the image of Sonic using Ninjutsu kept appearing in her mind.

That power made her very curious and fascinated.

So, the woman gritted her teeth and entered the House of Evolution in the dark night.

"Master! I brought back a Demon-level weirdo corpse!"

Sonic shouted at the top of his lungs.

Chu Yang pushed open the door and walked out of the laboratory, followed by Dr. Genus.

Chu Yang tilted his head and glanced, exclaiming, "Oh, the Underground King! Not bad, not bad. His body can be used to forge battle armor."

Sonic, who was about to take credit, immediately froze, confused, "Master, how did you know he was the Underground King?"

"By his appearance," Chu Yang said casually, "The Underground King usually looks like that."

Sonic: "…"

Sonic realized his master was teasing him and asked with a crestfallen, wronged expression, "Master, what do you mean by this?"

"It means you did bring back a good experimental subject, but the problem is you brought back more than just this one thing."

Chu Yang said exasperatedly.

"Huh?"

Sonic was utterly confused.

Dr. Genus adjusted his glasses and explained, "Ahem, Mr. Sonic, someone followed you back and found our base."

Sonic finally reacted, his face suddenly darkening, "I'm sorry, Master, I'll go take care of that guy right now."

Chu Yang waved his hand, "No need, they've already come down."

Tap, tap, tap~~~

The sound of high heels on the stairs grew closer.

First to enter everyone's sight were a pair of impossibly long legs, longer than Sonic's life, clad in black over-the-knee boots.

Further up was a very eye-catching dark green long dress, with a luxurious pearl necklace adorning her chest.

Even more eye-catching than the pearl necklace were her proud peaks.

Green hair, green clothes, an imposing figure, and beautiful looks—after gathering these elements, Chu Yang guessed who the newcomer was.

"The B-Class Rank 1 hero, Hellish Blizzard."
