The darkest day ever in the city of Z today was when a large number of mosquitoes from nowhere attacked the city of Z, causing unimaginable damage.

Mosquitoes swarm in swarms, seemingly endless, and kill people when they see them, but anyone who has been bitten by a large number of mosquitoes has all dried up and died.

The Hero Association has upgraded this mosquito plague to "Dragon" and sent S-class heroes to solve it.

It's a pity that Z City is a marginal city, and it takes time for heroes to arrive, but the people of Z City can't afford to wait.

But just when the people of Z City were desperate, the mosquitoes seemed to be guided by something, and all of them gave up killing humans, and instead went towards the center of Z City.

The appearance of the mosquito plague also attracted Saitama's attention, and he was curious to follow the direction of the mosquito, but unexpectedly saw Lisa.

When all the mosquitoes carried the blood of countless humans and integrated into the body of the mosquito children, her strength was enhanced to the extreme, and the strength of the original "ghost level upper position" was instantly raised to the "dragon level middle position".

Human blood not only strengthens the mosquito child, but also increases her speed, while giving her a bit of a burst of self-confidence.

Although Genos's body was badly damaged, the detector was still working normally, and when he discovered the strength of the mosquito child, he immediately alerted Saitama and Lisa.

"Run, her strength is already at the dragon level!"

Lisa was shocked when she heard this, she knew that when the weirdo level reached the dragon level, it meant that he had the lethality to destroy the city.

Dragon-level monsters usually require two or more S-class heroes to deal with.

Since the establishment of the Hero Association, there have not been a few dragon-level crises.

"None of you can leave today!"

The mosquito monster screamed and quickly attacked Lisa, her speed was several times faster than just now, and Genos's detection could not detect her movements, and it was too late to remind Saitama and the two.

In the face of the mosquito child's speeding, Lisa even showed a desperate expression.

"Boom!"

Saitama suddenly appeared on the path of the mosquito children, and no one saw his movements clearly, only saw him wave his hand casually, and the mosquito children hung on the outer wall of a building like a pile of rotten meat.

The sudden change caused Genos's CPU to short-circuit a little, and Lisa didn't expect the dragon-level weirdos to be defeated so easily.

On the contrary, it was Saitama, who seemed to have done something insignificant, scratched his head and said.

"So unbeaten!" Before he could contribute, he didn't expect the mosquito child to be shot to death.

Bang

The building that the mosquito child hit collapsed, causing Genos to wake up.

"May I ask the hero's name!"

"My name is Saitama!"

"Please take me as an apprentice!" Genos pleaded suddenly.

"Huh?!" Saitama didn't react a little.

Lisa noticed the sound of a police car in the distance, pulled Saitama and left, she didn't want to make a fuss.

When they got home, they found that the Northern Thunderbolt had returned, and had brought a gift.

"What's going on in my house!"

Saitama found that her home was in a mess like a typhoon passing through, and there was a big hole in the ceiling.

"When I came back, I saw these two things wreaking havoc at home!"

The Northern Thunder refers to two strange people, one looks like a toad and the other looks like a praying mantis, but at this time they are injured all over their bodies, and they have more air in and less air out.

"Who are these?" Saitama said angrily: "Why do you want to destroy my home!"

Saitama is worried about money, his house is rented, and he has to pay the landlord after it is damaged.

"They seem to be saying that they are from the House of Evolution!" The North Thunder doesn't matter.

"No matter how much, just let them lose money!" Bei Ying Lei grabbed the toad monster and shouted fiercely.

"Lose money quickly!"

As a wolf-level weirdo, the toad man felt that he was really unlucky today.

Originally, Dr. Evolution arranged for the mosquito child and the orangutan-reformer to kidnap Lisa, and he and the mantis man went to monitor the house of the Northern Thunder.

The mantis man saw that both Kita-Stygian and Saitama had left home, and in order to grab the credit, he dragged him to sneak into Saitama's house, trying to find the weaknesses of Kita-Styx and Saitama, but he didn't expect to run into Kita-Stygian Thunder and go home.

When the thief was caught, the mantis man simply broke out, and he wanted to catch the Northern Thunder without his might.

Of course, the result is self-evident, they didn't want to be human beings after being taught by the Northern Thunder, and the three of them fought and inadvertently destroyed Saitama's home.

If it weren't for the fact that Bei Ying Lei wanted the two weirdos to lose money, I am afraid they would not have saved their lives.

"We really don't have any money!" The toad man said with a bitter face.

"We don't usually use money, so we naturally don't have any money!"

Saitama didn't give up and said, "Then your evolution family will always have money to lose!"

Lisa couldn't bear to say on the side: "The point is not to lose money!"

"Don't you want to know why the House of Evolution found you!"

Bei Ying Lei and Saitama glanced at each other and shook their heads.

"It doesn't matter why he provokes us, he can't threaten us anyway!" The North Thunder stall said.

"You guys?!" Lisa was a little speechless, but after thinking about it, Saitama could kill a "dragon-level" monster so easily, and the strength of the Northern Thunder was unfathomable, so naturally she would not be afraid of the small evolution family.

Knock knock

While Lisa was silent, a knock on the door pulled her thoughts back.

Lisa opened the door and saw Genos standing intact.

"How did you get in good shape so quickly!" Lisa wondered, knowing that half an hour ago, Genos's mechanical body was still in tatters.

"90% of my body is mechanical, and if it breaks, I will replace it with a new set, and it won't take much time!"

Genos suddenly said solemnly and loudly: "I came to visit this time to ask Saitama Sensei to take me as an apprentice and teach me how to become stronger!"

Saitama and Kitastyra, who were in the house, naturally heard Genos's words.

"When are you going to take in your apprentices!" Bei Ying Lei looked at Saitama funny, as far as he knew, Saitama was confused with all his strength, let alone being a teacher.

"Teacher Beiming, don't make fun of me!" Saitama touched her head and said embarrassedly.

But Kita-Ray didn't mean to make fun of Saitama, he knew that according to the plot of "One Punch Man", Genos worshipped Saitama as a teacher, which kicked off his career as a hero.

"Let him in!" The Northern Thunderbolt beckoned to Lisa.

Saitama heard the command of the Northern Thunder, and it was not easy to stop it.

It was very strange why Saitama, who was so powerful, would respect the Northern Thunder so much.

"I won't take you as an apprentice, you better go!" Saitama never let go.

"Teacher, I am very sincere in apprenticing to my teacher!"

Bei Minglei's eyes lit up when he heard this, and he asked, "How much tuition have you prepared!"

"Huh?!" Genos was surprised: "I don't have any money!"

Bei Minglei's face was stunned, and he quickly gloomed, muttering, "There is no money again!"

Bei Ying Lei then targeted the toad man again.

"Say, where is your evolutionary house?"

"Lao Tzu is going to collect debts!". [.]
