Bofoyi didn't expect that the "golden human" in the mouth of the king of the underworld turned out to be Saitama.

Saitama has never been in contact with Bo Foyi, but through the relationship with the Northern Thunder, Bo Foyi also knows a little about Saitama and knows that his strength is above the Northern Thunder, but his personality is a little strange.

"I don't know this guy!" Beaufoyi wanted to hide his relationship with the Northern Underworld.

The Underground King smiled and said, "I know your relationship with the Northern Thunder, it shouldn't be difficult to get Saitama's blood!"

Bo Foyi was shocked, the power of the Underground King was even more terrifying than he imagined, at least the intelligence ability was terrifying, his contact with the Northern Underworld Thunder was carried out secretly, and he was still detected by the Underground King.

"Why don't you go yourself!" Bofoyi asked, "With the strength of the underground people, just tie Saitama directly!"

"What is the strength of Saitama, you know better than me, I'm afraid that even if I raise the strength of the whole clan, I won't be able to fight that monster!"

Bofoyi fell silent, to be honest, getting Saitama's blood was not a problem for him, but according to what the Underground King said just now, once the strength of the underground people increased greatly, the first unlucky ones would be humans.

"What do you have to exchange with me!"

When the Underground King heard Bo Foyi's words, the corners of his mouth curled, and he said happily: "I promised you before, as long as you help me activate the holy stone, I will give you all the technology of the underground people!"

"I still want to know the history of 6,000 years ago!" Boffoyi said in a deep voice.

"Yes, as long as you give me Saitama's blood!"

Bofoyi's robot shook his head humanely and said, "I want a deposit!"

"I want a blueprint for the space conversion device!"

The underground people did not immediately agree to Bofoyi, but pondered for a while, carefully considering the pros and cons before replying.

"I can give you a prototype of a space converter, but the design drawings can't give you!"

Bofoyi said categorically: "No, this matter is not negotiable!"

"Saitama is not an ordinary person, his blood is not easy to get, besides, how can I believe that you will not cross the river and tear down the bridge!"

The Underground King laughed, "I don't have to lie to you, and besides, you don't have a choice!"

A holographic projection suddenly rose to the left of Bofoyi, playing the whole process of the original transaction between Bofoyi and the King of the Underworld.

"As long as I pass this video on to the Hero Association, you will be ruined and will not tolerate human society!"

Beaufer was unmoved, and said with a smile: "Even if the metal knight is ruined, I just change the vest, no one knows the true identity of the metal knight!"

The Metal Knight has always acted as a robot, and Beaufoyi is hidden behind the scenes, and the video exposure has no effect on him, and the Underground King cannot threaten him.

The Underground King's eyes narrowed, staring fiercely at Bofoyi's robot, as if he wanted to see the operator in the distance.

"Give you a machine, the design drawings give you half, the core technology can't be given to you! That's my bottom line!" The King of the Underworld said solemnly.

Beaufoyi knew that the bottom line of the Underground King had arrived, so he stopped bargaining.

"Deal!"

The Underground King then gave Boffoyi a space converter and sent the blueprints to his mailbox.

"In three days, I'll give you Saitama's blood!"

As soon as Bofoyi got what he wanted, he immediately returned to the human world.

Along the way, Beaufor noticed that there were always a pair of seemingly non-existent eyes staring at him, those sent by the King of the Underworld to follow him.

"Looks like you're going to have to make a trip!" Boffoyi said to Dr. Evolution in front of the computer screen.

"I'll go find the Northern Thunder, be careful yourself!"

Bofoyi nodded and said, "I will send a hundred robots to attract the people of the Underground King, you take the opportunity to leave quickly!"

Soon a hundred robots flew out of the base in Bofoyi and scattered in all directions, and the stalkers sent by the Underground King were overwhelmed and obviously understaffed.

Dr. Evolution hid inside one of the droids, and after making sure that no one was following him, he changed his face and went to the home of the Northern Underworld.

The house where Bei Ying Lei lives now was arranged by Dr. Evolution, and he left a secret door in advance, which could lead from a building next to him to a room in Bei Ying Lei's house.

Five minutes later, Dr. Evolution came to the side of the mansion of the Northern Thunder Family, and sure enough, he found a lot of monitors, always keeping an eye on the surrounding situation, once he approached the building, he would definitely attract the attention of these people.

Dr. Evolution tugged at his collar, lowered his head, walked into the next building, cautiously went to the basement, and opened a secret door.

The secret door connects the two buildings, and Dr. Evolution successfully infiltrates the basement of the North Thunder family's mansion and then opens another secret passage.

Inside the secret passage was a small elevator, and Dr. Evolution shrunk back and filled the elevator to the brim.

The elevator leads directly to the top floor of the building, and the room of the Northern Thunder was built by Dr. Evolution himself, no one knows, not even the Northern Thunder.

When the elevator door opened, Dr. Evolution was surprised to see a pair of ketones.

As soon as Manli finished taking off her clothes, she saw the walls of the room suddenly open, revealing the Doctor Evolution with the body of the turtle roll inside.

At this time, how does Dr. Evolution look so obscene.

A man and a woman, their eyes facing each other, opened their mouths wide in surprise, and when Dr. Evolution looked down, Manly screamed.

"Pervert!"

Manly's voice was so loud that Dr. Evolution couldn't help but cover his ears, and then he saw Manli grab a sheet and wrap it around her body, pick up the high heels next to the bed and hit him.

"Kill you pervert!"

Manli shot mercilessly, the heels of his high heels hitting Dr. Evolution again and again, grinning in pain.

The heel was sharp, and it hurt extremely much to hit the person, and Manli shot extremely hard and more powerful under the grief and anger.

"Stop, I'm not a pervert!" Dr. Evolution said that Manli was too fast and heavy, and he shrank in the elevator and couldn't move, so he could only try to protect the vital point.

"Where's the pervert!" Manli's door opened, and Fuyuki and Lisa rushed in, and when they saw Manli beating up Dr. Evolution, they guessed something.

"I'll help you!"

Both women, Lisa and Fukiyuki put aside their preconceptions and teamed up to help Manli beat up Dr. Evolution.

"I'm really not a pervert!" Dr. Evolution exclaimed bitterly.

Although Dr. Evolution has superhuman intelligence, his physique is still in the category of normal people, and he was besieged by the three women, and he didn't even have the power to fight back, so the three women grabbed him out of the elevator, rolled up his sleeves and went on, and hit Dr. Evolution with a small fist "poof".

Lisa, in particular, almost used all her internal strength, but fortunately she still has some sense, otherwise Dr. Evolution would not be able to see the Northern Thunder.

At this time, the three of them, Saitama and Genos, were guests at Banggu's dojo, happily eating hot pot, and they didn't know the tragic appearance of Dr. Evolution.

When the three of them returned from the Banggu Dojo, he saw Dr. Evolution, whose face was bruised, covered in wounds, his hair was as messy as a chicken nest, and he was tied up like a dumpling, looking at him with tears in his eyes.

"Northern Thunder, save me!"

At this time, there are still three daughters sitting on Dr. Evolution!
