It's been three days since the hero exam, and Saitama and Lisa have to go out on the streets to perform heroic deeds to maintain their rankings due to their low ranking.

The Northern Shadow Thunder is a B-level hero, so even if he doesn't do any heroic acts, he won't be removed from the Hero Association, and his ranking will drop at most, so he didn't accompany Saitama and the two to the street together, but went to find Dr. Evolution and Bofoyi alone.

Ever since Dr. Evolution got in touch with the Northern Thunderbolt, the Northern Thunderbolt introduced him to Bofoyi.

The two genius scientists hit it off at first sight and discussed the evolution of life.

Although Beaufoyi is a genius in mechanics, he has changed the direction of his research since he met the Northern Underworld, and it does not conflict with the genetic research that Dr. Evolution has always had.

Coupled with the blood and martial arts cheats provided by the Northern Thunder, it really allowed them to study something.

In a building on the outskirts of Z City, two scientists with deep pockets bought the entire building and used it as a research institute.

When the Northern Thunderbolt arrived, a robot led the way.

The building looks ordinary, but in fact it has long been transformed by Bofoyi, containing many armed robots, and the entire wall is reinforced many times, saying that it is a laboratory rather than a bunker.

Beaufer doesn't trust anyone, and there is only one person in the building, except for robots, Dr. Evolution.

After Dr. Evolution's evolutionary home was destroyed by the Northern Thunderbolt, he moved his laboratory to the building in Beaufoy, and the two of them shared their research results on an equal footing, with one mind on the study of human evolution.

When the robot arrives at the two's lab with the Underworld, he finds Dr. Evolution and Poffoyi arguing fiercely.

"The essence of this internal strength is the life energy of the human body, and only in the human body will it be infinitely enhanced!"

Bo Foyi has a different opinion: "In the final analysis, internal power is just a kind of energy, as long as you find a way, even a robot can store and enhance!"

Because of the different fields of science, two scientists usually have disagreements, and discussions and quarrels are not uncommon, but it is in these quarrels that their research has made breakthroughs.

"It seems that you have studied the essence of internal strength!" Bei Ying Lei came to the two scientists with a smile.

Dr. Evolution was unkempt at this time, and his handsome face was full of exhaustion.

Bo Foyi was not much better, but the two tired people were surprisingly interested, and after seeing the North Thunder, their eyes lit up.

"You've come just in time, we've finally figured out the nature of internal forces!" Bofoyi said to the Northern Thunder.

"Internal force is essentially a sublimation of life energy, which can also be created through scientific methods!"

Dr. Evolution added: "However, we have found that the internal forces dissipate quickly after losing the human body as a carrier, and what is more troublesome is that the life energy is different from each other, and it is difficult to transfer them to each other!"

"And every type of internal force has an element that changes the character!"

Bo Foyi took out the Taoist magic skill "Pure Heart Formula" that Bei Shenlei had studied for him before and said.

"According to my research, the personality of those who practice this martial art book will become more and more indifferent!"

Dr. Evolution took out a copy of the Demon Gate martial arts "Blood Spirit Skill" and said, "Those who cultivate this kind of martial arts will become more and more bloodthirsty!"

Bei Minglei nodded and agreed, each sect and each school of martial arts has its own characteristics, Taoism is indifferent, the demon gate is bloodthirsty, and the Buddhism is transcendent, all of which are different.

Take Bei Ying Lei himself as an example, when he practiced the "Wordless True Scripture", he didn't feel it at first, but when he practiced the "Qi of the Universe" and reached the top of his cultivation, his character was inevitably affected by divine skills, and his human nature gradually became indifferent, and his personality became more and more arrogant, and there was a feeling that everything in the world was an ant.

It wasn't until this time that he lost his internal strength, his martial arts were abolished, and he could only cultivate ** strength, so that he got rid of the restrictions of his divine skills, returned to his natural nature, and was even a little childish sometimes.

Calculated carefully, the fourth generation of the North Shadow Thunder is almost 70 years old, belonging to the elderly, but the personality is getting smaller and smaller, like an old child, but it makes people easier to get close.

The original Northern Thunder has a dusty temperament and a decisive personality, but it is inevitable that he will reject people thousands of miles away, and others will be afraid of him, worship him, and even admire him, but the only one will not get close to him.

And now the Northern Thunder is more popular.

Bei Minglei himself also understands the influence of the "Wordless True Scripture", but in order to gain great power, he has no choice.

"Is there a way to take out the charging crystal in my dantian!"

A day ago, the Northern Thunder informed the two of them about the loss of their internal strength, not because the Northern Thunder trusted them, but because with the growth of their strength, the Northern Thunder no longer needed to hide it.

"I've worked with Dr. Boffoy, but I haven't thought of a solution yet!"

"The charging crystal in your dantian is wonderful, with our current technology, we can't find it, how can we take it out!"

Bo Foyi had already inspected the dantian of the Northern Thunder with Doctor Evolution, not to mention the charging crystal, even if he didn't see a single hair, he couldn't solve the problem of the internal force of the Northern Thunder at all.

The "Charged Crystal" belongs to the highest technological crystallization of the "Olympus Divine Domain", surpassing the world technology of "One Punch Man" for hundreds of years, and no matter how talented Ren Bo Foyi is, it is impossible to shorten the gap of hundreds of years.

Bei Ying Lei was a little disappointed, but he didn't care, he had expected it, so he changed his words.

"Then the pair of sisters and brothers I asked you to find, is there any news?"

It has been a few days since Bei Ying Lei blew up his identity, and there is all his information on the official website of the Hero Association, and he hasn't even changed his name, just to bring out the Athena sisters and brothers.

To unlock the bell, you must tie the bell, and if you want to get rid of the charging crystal, the North Thunder can only go to the Athena sisters and brothers.

In the past, his strength had not recovered, so he avoided Athena, but now that his strength has reached the "peak of the Boundary Breaking Realm", and with Saitama, a god-level helper, he finally no longer has to be afraid of Athena.

It's a pity that Bofoyi gave Bei Ying Lei an unwanted answer.

"I haven't found them, I've used all my connections, but unfortunately I still haven't found them!"

"Where's the news of the mysterious organization?"

Dr. Evolution also shook his head and said, "There is no news, that base has been blown upside down, no clues have been left, and we have not found any news about that organization!"

Beauvoyi suddenly proposed, "I suggest you use the power of the Hero Guild to investigate!"

"The current Hero Association is already the largest organization in the world, as long as you can become the top S-class hero, you also have a certain right to speak in the Hero Association!"

"And after you become famous, it will be easier to attract the attention of that pair of siblings and mysterious organizations!"

Bei Ying Lei lowered his head and pondered: "Most of the tasks released by the Hero Association are just some simple tiger-level tasks, and the hero ranking is slowly rising, so I don't have that much time!"

Beaufoy pulled out a tablet and said, "Maybe now is a chance to be famous!"

The Northern Underworld saw a name on the tablet "Bounty Hero".
