The Flowing Water Rock Shatter Gym is built on the edge of a steep cliff, and the road up the mountain is only a stone staircase that seems to be endless at a glance.

Since the Sea King incident, Gu Xin has often been in contact with Saitama and Genos, and when the silver fangs Banggu, who ranks third in the S-rank, invited Saitama to visit the boxing gym, Gu Xin happened to be there, so he was invited together.

On the smooth floor of the training ground, his hair and eyebrows have turned gray, and his face is full of wrinkles and ravines, but he is full of energy, Bang Gu is playing flowing water and rock crushing fists in front of Gu Xin, fast and strong, as if washing the waterfall of the earth, a set of clouds and flowing water, not at all like an old man who has passed the age of sixties.

After the end of the Flowing Water Rock Fist, Banggu, who was originally alive and vigorous, became a rickety old man again, if it weren't for the name of an S-class hero, he would look like an ordinary old man.

After Banggu sells Saitama and Genos to no avail, he has a new idea,

"Your recent reputation is very famous, but in just ten days, you have risen from 350 in C to 37 in A level, known as the most terrifying newcomer in history, I think I have a good talent, how about Gu Xin, do you want to try to learn it?"

Gu Xin directly refused, if he didn't have a contract war demon, he could still learn it and improve his combat power, but what he got by borrowing the power of the war demon was hot weapons or cold weapons, and he didn't fight with his bare hands.

"Mr. Silver Fangs!"

Everyone was attracted by the shouts at the entrance of the gym.

I saw a man in a suit who was sweating profusely and panting with exhaustion, gasping and saying: "I was sent by the Hero Association, and the Association issued an emergency convening order for S-level heroes, please follow me to the headquarters of the Association!" ”

"That's Mr. Genos over there, right? All S-Classes will need to be present this time, so please come with me Mr. Genos! ”

Gu Xin looked at all this and smiled secretly in his heart, he had a good relationship with Saitama these days, and he also came to the boxing gym because of social fear, just so that he could go to the headquarters of the Hero Association with Banggu on this day.

When Boros invades in a spaceship, he can greatly increase his level as long as he does his part.

"Garrank, please watch the house." After Banggu finished instructing his disciples, he took Gu Xin and the others and left with the people of the Hero Association.

……

City A, the headquarters of the Hero Association.

The seventeen heroes of the S-rank, except for the metal knight who ranked sixth in the S-rank and the blast who was the first in the S-rank, were all here.

Gu Xin, Saitama and Genos sat at one end, and the remaining fourteen S-class heroes sat on both sides, and the cadres who had personally notified him of his promotion to A-rank heroes sat opposite each other, telling everyone what had happened.

To put it simply, it is the prophet who left a prophecy of "the earth is not good" before he died, and within half a year, there will be an apocalyptic disaster.

Gu Xin knew that the disaster at the top of the dragon would come later, and then only the Hero Headquarters in the entire City A would survive, and the rest would be in ruins.

He wanted the Hero Association to evacuate the people of City A in advance, but he was powerless, no one would believe him, even if he was S-level, he couldn't let so many people take refuge in other cities for the sake of the illusory prophecy.

Outside the headquarters, a huge H-shaped spaceship obscured the sky, shrouding most of City A in darkness.

The surreal hull lit up with white balls of light, and in the next second, the balls of light plummeted down like a torrential rain, booming, accompanied by explosions one after another, and City A was reduced to ruins as if it had been hit by a nuclear attack, and even the sturdy association building was tilted like the Leaning Tower of Pisa.

The S-class heroes rushed outside and were shocked to see the destroyed City A.

The vanguard sent by the cosmic overlord Boros, the dragon-level Meruzagarudo, was eyeing him not far away, and even the disciple of the Atomic Samurai, the second rank of the A-rank, was cut off by him.

It had five tumor-like skulls on its neck, all five pairs of eye sockets were empty, without eyeballs, and its earthy brown body was covered with chaotic muscle lines like dead tree roots, and its body could be deformed at will.

After a brief temptation, Meruza Garudo split into five to fight several S-class heroes such as Silver Fang.

After Gu Xin let the war demon eat his left arm, a bright red cannon barrel with a thick bowl mouth wriggled from the severed arm, and met one of them.

Meruza Garuda is completely at the dragon level, but after separation, each one is only at the ghost level, plus the opponent's light enemy and Gu Xin knows its weakness, Gu Xin may be able to kill one by surprise.

"The inferior races still dare to resist, I will tear off your limbs and keep them on our spaceship."

As he spoke, one of the clones of Meruza Garudo's right hand wriggled into a huge hammer, and with the sound of whirring through the air, it slammed towards Gu Xin!

The latter's right arm was carried across his front of him, and with a snort, the huge impact of the hammer directly cut his forearm in two.

Gu Xin took the opportunity to pull out the barrel of the cannon from behind, and after the cannon fired, Meruzagarudo was blown off the head by the sudden shelling, but the latter was not nervous, because it only took a few moments for it to recover.

"Ghost now!"

The black ghost that had been preparing to attack next to him suddenly burst out under Gu Xin's order, and the hand wrapped in the black bandage was in the flesh in mid-air, quickly grabbing and pumping, and a black bead like a glass bead appeared in its hand.

Click!

The black ghost squeezed hard, and the black beads shattered in his hands.

Meruzagarudo's body melted into a puddle of flesh.

Other S-class heroes are still fighting hard, but Gu Xin can kill Meruza Garudo's clone one one step ahead of them, not that Gu Xin is stronger than Banggu and others, but that Gu Xin has the information.

Gu Xin reminded: "This guy's weakness is in the black bead in his head! ”

The Atomic Samurai laughed: "I was actually topped by an A-rank hero, and I will laugh out of my big teeth when I say it!" ”

In the end, with the concerted efforts of the S-class heroes, all the beads in Meruzagarudo's skull were pinched and exploded.

"You've got to bandage it as soon as possible." Banggu noticed Gu Xin's broken arm, which was still bleeding, and led him to treat the wound.

While Bangu was bandaging his severed arm, Koshin looked at the spaceship in the sky that looked like a mountain floating in the air, and thought: Saitama should be up to Boros.

It's okay for him to fight Meruza Garudo with S-class heroes, but the battle between Saitama and Boros is not something he can get involved in.

Boros is the overlord of the universe and is tired of endless plundering until twenty years ago a soothsayer predicted that Earth had an opponent to match.

Poros then came all the way to Earth, but he didn't expect to meet Saitama, and he didn't know that earthlings had hair before he died.

Furushin guessed that the soothsayer was not prophesying Saitama, but a wolf.

Bang!

The sudden explosion at the top of the spaceship attracted everyone's attention, and the mushroom cloud caused by the explosion was like a giant beast, roaring to remind everyone that there was a terrifying battle going on inside the spaceship.

About a quarter of an hour later, the spaceship of the Cosmic Dark Matter Pirates fell in flames, kicking up a tsunami-like cloud of smoke.

Saitama walked out of it dirty, and only Gu Shin and Genos were present who knew that he had just saved the world.
