Too large size is beneficial and harmful to Ding Yi.

The secret technique selected by Ding Yi is a method that can freely change the size of the body.

However, no matter whether it becomes bigger or smaller, the essential strength will not improve at all. Moreover, if it becomes too large, its strength will decrease, which is not a good thing.

Fortunately, what Ding Yi wanted this time was not to become bigger, but to become smaller. If it was smaller, it would have no impact on his strength.

Ding Yi originally looked down upon such a secret technique.

After all, no matter how big or small you become, you cannot improve your strength. So what can you learn to do?

If it is a magical world similar to the prehistoric world, such a magical power that can improve its strength, Ding Yi will naturally start practicing and comprehend early. However, Ding Yi didn't like this secret technique before.

However, it is a special situation now. Ding Yi needs to have his own body size smaller. Otherwise, when he encounters an enemy that is difficult for the body to deal with and needs to have his own body field, he accidentally blows up the earth himself, which would be a joke.

There are so many secret techniques and martial arts in the inheritance memory of the Chiyang Volcano clone. After Ding Yi picked it up, he chose this secret technique.

Obviously, the ancestors had encountered similar troubles in the Chiyang Volcano clan, so the inheritance of this secret technique that could not be improved was solved by Ding Yi's urgent need.

This secret technique is not difficult to learn. Ding Yi is confident that he can learn it in a few months and use it freely.

According to the three levels divided in the secret technique, there is almost no difficulty in achieving the first level, but the first level can only become larger and smaller three times, which cannot achieve the effect Ding Yi wants.

The second level is a bit difficult, but it is not difficult for Ding Yi to do it. Once you learn the method of changing the second level, you can make your body bigger and smaller thirty times.

However, this was not what Ding Yi wanted. What he really valued was the effect that could be achieved by practicing the third level to the perfect state.

Once this secret technique is practiced to the third level of perfection, it can easily change the size of the body, which can increase by billions of times or smaller by billions of times.

With Ding Yi's Chiyang Volcano clone, it can be reduced to a height of one or two kilometers after it becomes smaller, which is already the limit that this secret technique can reach.

Although one or two kilometers is still very large, there will be no situation where the earth will explode without accidentally seeing it.

Time passed, and Ding Yi had been in the central city for more than a month in a blink of an eye.

The security of the central city is much better than Xinghai City. In addition, Barry is working hard to combat crime, which has made considerable contributions to the reduction of the crime rate of this city.

For more than a month, Ding Yi not only asked his clone to work hard to comprehend the secret technique, his body was to eat and drink every day, or occasionally return to Xinghai City to judge some guys who jumped out to find uncomfortable.

During this period, Barry has been working hard to learn how to become a successful superhero, and he occasionally comes to ask Ding Yi for advice.

Of course, it is not to ask how to kill people. Barry is Barry, he is not Ding Yi. Even if the criminals kill many people, no matter how evil and evil things they commit, he will only lock them up and will never kill people.

Ding Yi would not agree with Barry's practice of only keeping in check but not killing him.

But he was too lazy to correct Barry. Whatever he loved was his time, and he didn't care what Ding Yi was doing.

On this day, Ding Yi came to the Sitte Cafe as usual and enjoyed a cup of afternoon coffee.

This cafe is where Iris works. Barry and the others like to come here. Ding Yi has been used to it after coming a few times. Besides, the coffee here tastes really good.

While drinking coffee, Ding Yi looked at the magazine in his hand, just like other customers in the store.

At this moment, his cell phone in his pocket suddenly rang.

Putting down the magazine, Ding Yi took out his phone and looked at the number on the screen.

"Barry, what did he ask me for at this time? Shouldn't he be helping the people in the city and working voluntarily?" Ding Yi smiled and muttered, pressing the answer button and putting his phone in his ear.

"Hi~! Barry, is the work going well?" Ding Yi greeted with a smile.

Barry's voice came from the other end of the phone. There seemed to be a lot of people next to him. He deliberately lowered his voice and said, "Hey~! Chris, guess what I just met? Another superpower criminal, I think you may be interested in coming and taking a look. That guy seems to be quite special."

"It's very special?" Ding Yi smiled and said, "Okay, then I'll go to the cutting-edge technology laboratory to wait for you."

"Okay, see you later!"

After hanging up the phone, Ding Yi looked at the magazine on the table, shook his head and smiled, then got up with the coffee and walked out of the cafe.

Cutting-edge technology laboratory.

Ding Yi walked into the main control room on the surface, and Barry was indeed not here yet.

"I heard that Barry met another superpowered criminal and said it was quite special. What's the special method?" Ding Yi walked in and asked.

Caitlin and Sisco were both there. When they saw Ding Yi coming in, they also greeted him with a smile.

Even Dr. Wells, no matter what he thought, was still pretending to be very welcoming Ding Yi on the surface.

"Barry is late again." Ding Yi sat down and said.

Almost as soon as he finished speaking, Barry arrived.

"Hi~! Man, it's not good to say bad things behind the scenes." Barry walked over with a smile, greeted Ding Yi, turned to look at Caitlin and the others and asked, "How about it, have you developed anything about the new guy?"

"Anger, hatred," Dr. Wells said. "These strong emotions can stimulate the brain and make people do things that they don't do or dare to do."

"Just just now, those people were like crazy in the bank. Their eyes looked at people as if they were all their enemies who killed their fathers. This state lasted for five or six minutes." Barry said, "Do you think this guy's ability is the emotion that controls people?"

"Maybe it just makes people angry," Sisco said.

At this time, Caitlin also came over with a USB flash drive.

"Detective West got the tomography that the hospital did for those in the bank, look."

When the USB flash drive was put into the socket, a picture soon appeared on the screens of several computers.

Barry and the others were discussing, but Ding Yi frowned, as if he was thinking about something.

Suddenly, Ding Yi snapped his fingers and said, "I remembered it!"

"What?" others looked at him one after another.

ps: Happy Christmas to everyone!
