The frustration of knowing who the killer is, but not having enough evidence to arrest him, is unbearable. But Batman didn't show the slightest bit of anxiety. He knew the mad hatter, the madman's purpose was certainly not as simple as developing a medical supply that would go down in history, the poor family was undoubtedly consumed by the mad hat as a test subject, and it was doubtful that after the death of the family, the mad hatter immediately hired two people to search for the chip.

"Bruce? What are you doing? ”

Seeing the people who were busy on the test bench as soon as he returned to the cave, Clark asked with some curiosity.

"Mad hatters' chips come in pairs"

According to the Mad Hatter himself, there is a main core that can connect to the human brain, and then connect the secondary core to the spinal cord under the fault, so that a virtual radio bridge can be grafted at the place where the spinal cord is broken, so as to replace the role of the spinal cord, which sounds very happy, doesn't it?

However, if the Mad Hatter is not lying, then the real effect of this on the chip should be that the secondary core is responsible for hypnotizing the people it comes into contact with, and the main core sends controllable radio waves, so that the Mad Hatter can control the people he wants to control. But why is it that only this chip that fell into his hands is independent? Bruce was lost in thought as he watched the inspection data on his computer.

"Bruce, you see... Did the Mad Hatter let you see that shadow too? ”

Clark asked as carefully as he could, if the Mad Hatter had manipulated Bruce into seeing Jason's apparition.........

“... No, he shouldn't have known I got this chip, let alone .."

Bruce still remembers the confrontation with the Mad Hatter that day. He believed that the Mad Hatter would have wanted to get his hands on the chip so that he could control him, but the Batcave's natural advantages made it impossible for any radio waves to penetrate the rock-based underground cavern. It is simply not possible to control this chip by emitting radio waves from the outside, let alone how much power it takes....

"What's wrong? Bruce? ”

Watching Bruce's fingers suddenly pound on the keyboard, and the instrument used to scan the chip suddenly increased in power, which made Clark wonder what Bruce had noticed.

"Low-frequency sound waves are indeed more convenient for hypnotizing them, which are far beyond the range of human hearing, and will not cause any discomfort to the human body at all, which is very suitable for giving orders to the subconscious when people are relaxed in their hearts, using this principle, psychologists usually use low-frequency music to relax patients, so as to achieve the purpose of psychological treatment, but low-frequency sound waves have a fatal weakness..."

"Penetration"

"Yes!"

Clark immediately reacted to the point of Bruce's words. Low-frequency sound waves have a wide coverage but poor penetration, emitting such low frequencies from the chip that a thicker box can shield them, which is why Bruce was hypnotized and Alfred was not. Because the bruce is in contact with the bare core for a longer period of time, it is more susceptible to low-frequency sound waves.

If the Mad Hatter wants to use this thing to control the power of Gotham, then there must be something to solve this weakness, if you guess correctly, the so-called main core plays this main role, in other words, the secondary core is the main core, and the main core is like an amplifier....

"But if the mad hatter's purpose is to bring him a lot of wealth with this chip, then these chips must be used on the rich"

"But not all rich people have this need, right?"

Clark raised his doubts, this kind of chip has a very narrow range of use, and most people can be excluded from the role of the chip. How can the Mad Hatter have to pay for his losses?

"That's the answer I'm looking for"

Bruce didn't refute Clark's question, as he was also struggling with the question. After screening all the eligible people in the family from the computer, I found only three people with a higher probability of purchasing.

One of Gotham's current councillors, Moore. Lee, his eldest son, who had previously fallen off his horse due to equestrian sports, had caused a high paraplegia; Gold. Wright is now a rising star in the business world, not as big as the Wayne family, but also important in the business world of Gotham, his wife was paralyzed in a car accident; The remaining one is Bruce, who has a well-known extreme hobby. Wayne, it is indeed very common sense to infer that it is not impossible for the heirs of the Wayne family, who love extreme sports, to buy an "insurance" for themselves. But these people are only likely to buy it, not necessarily buy it.

What's more, the main means of hypnosis of this chip is low-frequency sound waves, and it is difficult to say whether this effect will be achieved after being embedded in the human body. And in the case of Bruce himself, the only things that will cost him money are those that are technically mature, apart from those in research. He will not pay for this new product, which has just been developed and is not supported by any successful experiments.

The Mad Hatter must have a plan to get his chips into the hands of the people he needs to control.......

Things were moving much faster than Bruce had imagined, and it was only a few days before an invitation on his desk made everything clear.

This invitation letter from the St. Lawrence Institute, in addition to sending blessings, also invited him, the sponsor, to attend a special press conference of the Institute as a special guest in two days. The reason why it is special is that the institute intends to raise funds through auction of the first five sets of chips, and the funds raised are mainly used to help volunteers perform surgeries.

Medical supplies are absolutely not allowed to be marketed without human experimentation, and Mad Hatter's chips, which are completely new products, need to be strictly regulated.

Volunteers are nothing more than those who are willing to take risks for various reasons and are willing to do experiments.

"Humph! It's a nice name."

Bruce laughed at the mad hatter's attempt to use charity to spread the chips, which was a bit of a surprise to him.

It seems that the Mad Hatter did not intend to bury these chips in the body he wants to control in the first place, which also confirms Bruce's guess that low-frequency sound waves are the main body of hypnosis.

"Will you be there?"

Alfred asked dutifully, although it was true that Bruce was in a low mood during this time, he unknowingly hypnotized Batman, which made the old man feel worried.

"Of course, and I'll be the one to shoot the first pair of chips."
