Roger simply explained the chakra ball in his hand. He was not worried that Erica or others could understand the nature of ninjutsu or chakra from these simple descriptions.

Knowing the source of a person's power is completely different from whether he can resist the power of this person.

Just like the future Iron Man, everyone knows that Tony relies on high-tech steel suits to have power beyond ordinary people.

But even if those who can't beat him know this, they still can't beat him.

And Roger has no intention of hiding his abilities.

Even if you know that chakra is my source of strength, even if you know all the ninjutsu I know, even if you know the fighting style I am good at, so what if!

Instead of carefully concealing your abilities, it is better to find ways to further improve your strength.

As long as you have strong enough strength, why worry about the conspiracy and tricks of those ghosts and monsters?

Same push is the kingly way!

Unparalleled is the mystery!

Not long after Roger finished explaining to Erica, the chakra ball in his hand dissipated into the air and turned into airflows.

Compared with the previous three stages, the fourth stage of Rasengan Practice is the real highlight.

It is not very difficult to condense the chakra in your hands at high speed and irregular flow. The difficulty is how to maintain and solidify for a long time.

The spirulina that cannot be maintained for a long time is like a water ball, and it can be broken with one stab, and does not have real combat value.

Although Erica didn't know what chakra was, she didn't know what spirebra was.

But she saw something called power on this chakra ball called light blue.

A ninja with chakra is the real ninja.

For some reason, such an idea suddenly popped up in Erica's mind.

Dissipate again and again, forming over and over again.

Every failure consumes part of Roger's chakra.

Ten times, twenty times, fifty times, one hundred times...

Roger could not remember how many times he had practiced. His only feeling now was that the chakra in his body was about to reach the final critical line, which was also the first time he had realized the feeling that chakra was about to be exhausted.

"The last time, whether it succeeds or not, it's all over today!"

Like the previous exercises, the last attempt failed without any suspense, and no miracle was born because it was the last one.

After moving his stiff body for a while, Roger looked up at the clock on the wall, and it was 3:45 in the morning.

Just as he was planning to use the last chakra to use the flying thunder god to return home, he vaguely heard the faint sound of fighting coming from the alley below the office.

As a weapon master with cold weapons, although the fighting sounds coming from were very weak, he could hear it at once that it was the sound of the samurai sword impacting.

In places like New York, it is not a strange thing to hear gunshots.

But in the middle of the night, those who would use samurai swords to fight were the only ones who were famous for their mad ninjas.

Could it be those crazy ninjas who join hands?

Driven by curiosity, he came to the window and looked in the direction where the fighting sound came.

The one who fought in the alley below the office was indeed a ninja, but it was not the hand-joining ninja he imagined.

One of the parties in the battle was none other than Erica, who had just become an assistant to the firm.

At this time, Erica was still dressed like a working woman during the day, but what she did now had no similarities with that of a working woman.

Erica, holding a samurai sword, fought against three enemies wearing ninja suits of different colors.

After watching it casually for more than ten seconds, Roger realized something was wrong.

Whether it was Erica or the three unknown guys on the other side, although their offensives looked extremely fierce and all their moves were attacking the vital points, Roger did not see any murderous intent on them.

Although I don’t know what relationship Erica has with the three guys opposite, as Erica’s current boss, Roger feels that he needs to go there.

"Erika, stop!"

"You are no match for the three of us. If you are obsessed with it, don't blame us for being ruthless!"

"Erika, go back with us. We can solve the problems of the joining party slowly!"

As soon as Roger came to the alley, he heard the words of the three ninjas and at the same time he figured out the origins of the three people.

There will be no one else who will say such words to Erica except those of the Holy Society.

Erica seemed to have not heard the words of the three people, and her attack became more and more fierce, and she was silently preparing to retreat.

However, the three Holy Ninjas on the opposite side soon noticed Erica's plan and stopped holding back. They forced Erica to a defeat in an instant.

When Erica was about to be defeated and then forced to take away, Roger, who had been in the shadow of the alley for a while, finally came out.

"Does the Holy Society only bully the less? And they bully a woman. Don't you feel ashamed?"

Although there is not much chakra left in his body, Roger still doesn't take the three ninjas from the Holy Society seriously.

Through the observation just now, he was 100% sure that even if he didn't use chakra, the three Holy Ninjas were no match for him at all.

"Who are you? Since we know that we are from the Holy Society, we dare to express ridicule!"

One of the men in a dark yellow ninja suit said sternly.

"Who am I? I am Erica's boss!"

"You are under my office and attacking my assistant, you will be a little too arrogant!"

Roger said as he walked, and when he finished speaking, he happened to come to Erica's side and took the samurai sword in Erica's hand directly over.

"If you want to take Erica away, I will beat me!"

"Or, the people of your Holy Society only dare to bully women when there are many people?"

After being ridiculed by Roger one after another, even those who have no temper will inevitably get a little angry now.

"A boy who doesn't know how to be tall and strong is, don't think that knowing some fist and foot skills can insult the Holy Spirit!"

The guy who spoke was still the guy wearing a dark yellow ninja.

"Boy, my name is..."

Just as he was about to sign up for his own registration, Roger interrupted him in time: "I'm not interested in knowing the names of some small characters. Your names are not worth my waste of any brain cells!"

"You're looking for death!"

It is estimated that this Holy Ninja has never been ridiculed like this. After hearing Roger's words, his already uncontrollable anger completely erupted.
Chapter completed!
