In the basement, Anna is lying on a fume hood with protective goggles, a tweezer in one chubby hand and an air gun in the other.

A soldering iron is clamped between the tweezers.

She's soldering circuit boards.

The brainwave relay amplifier construction is in the final stages.

In the whole of Xavier Castle, the only thing Anna was satisfied with was the basement, which was 10 times the size of the original small workshop of the Manor House B, with 50 small rooms, each of which was extremely large.

After the wall is opened, it is even possible to build an underground football field, small.

Maya and David have completed the final handover, and now Xavier Castle officially belongs to the Hansen family.

Finally, Maya has a little conscience, and the name of Anna is left on the property title, according to Maya, to save the inheritance tax in the future.

Norman Osborne is preparing supplies at Anna's request, and the basement is currently being renovated.

Recently, however, Anna has not been involved in engineering construction, and she is now focusing all her energy on the brain-computer interface project.

The last time the B manor exploded, it was a little later, and she didn't need the sacrifice of the Egger robot at all.

At the beginning of the snake and mouse war, she released 64 guinea pigs.

Each guinea pig carries an infrasonic generator with double the energy level, and the generator is pressed under the iron buckle, and as long as it reaches the designated place, it can temporarily build an infrasonic resonance network, which is enough to wipe out Lady Hydra and the others unscathed.

Unfortunately, it is too difficult to control the mice, and it is necessary to get them to accurately recognize commands, and the position error is within a few millimeters, and it is not enough to make them move.

The last brainwave amplification receiver was made by Anna on an improvised basis, and the target mice could not be accurately identified at all.

The result can be imagined, after adjusting for a long time, the mice have not been fully arranged to the designated place.

Then the Egger robot blew itself up.

64 guinea pigs are useless.

After the last lesson, Anna felt that she should do a good job of brain-computer interface.

In fact, the potential of brain-computer interfaces is enormous.

As Dr. Zola said, using brain-computer interfaces, people can control machines, machines can control people, and finally people can control people by controlling machines.

Dr. Shortneck is saying that it will take at least fifty years to reach the level where people can control people beyond intermediaries.

All Anna is doing is controlling the machinery.

Press the helmet on the round head.

The helmet has electrodes, capacitors, memory, solid state drives, CPU, WiFi generator and receiver, which is a small computer.

Anna built every line of the helmet, strong and weak electricity, even the internal wiring of the CPU.

She designed a special instruction system for the brain-computer interface, which was placed inside the CPU.

Then I approached Intel and asked them to rebuild the CPU circuits according to their own design drawings.

After pressing the helmet button, the red, yellow and green indicators flashed in turn, and finally stayed at the green light, and the electrodes and the scalp were in contact, and the graphene in the antenna and cerebrospinal fluid was transmitted.

Brainwave receiving amplifier is operating normally,

The graphene and X gene expression protein mixture was injected by Anna herself with a robot.

A local anesthetic was indicated, and a needle was inserted from the original anterior halogen position.

Penetration of the anterior halogen door is minimal damage to the skull.

Practice has proved that the expression protein function is good, in order to prevent hackers from hacking in when they are not paying attention, for the sake of safety, Anna used graphene to make a switching circuit and deliberately controlled the transmission bit rate.

Now Anna is ready to let go.

The command system contains 156 operating instructions, all of which are placed in computer instruction registers.

Anna's instructions are goal-oriented, such as giving the robot a command to bring the bottle.

The cerebral cortex transmission command is translated to the expression protein through graphene, and the expression protein output enhancement signal is returned to graphene, and finally the graphene is filtered and amplified, and then transmitted to the helmet signal reception, and then transmitted to the robot through the antenna after the signal reception.

The robot has an internal functional computer, and after receiving instructions, it will analyze the optimal path and the operations he needs to do at each locus of the path, and finally take the bottle to Anna.

At present, Anna can operate the robot to do simple operations.

The robot no longer has Parkinson's disease like in Building B's manor, and the mechanical adjustment of all parts of the function is relatively smooth.

This is just part of the application, and the brain-computer interface also has a super powerful function.

The information received by the eyes and ears is fed into the helmet computer, which produces a vector image and sends it back to the cerebral cortex.

To put it simply, it is to digitize what you see and hear and extract key information.

Don't underestimate this part of the app, it's actually quite powerful.

What the human eye sees is a dot matrix bitmap, and the data obtained is all fuzzy data.

After computer processing, Anna can use the data world, such as the height of the castle, Anna can directly use her eyes as a receiver, plus the position she is standing on, and the distance between the retinal lens to accurately calculate the height.

For example, according to the data obtained by Anna, the highest height of the castle is 21.5 meters.

Based on the latitude and longitude of Westchestershire, the angle of incidence of sunlight, and the length of Anna's reflection standing under the sun with her back to the sun, Anna can measure her height - 1.15 meters.

The helmet then makes a timer, and the bit is removed by time, and Anna can accurately calculate the speed, and the final speed is divided by time to calculate the acceleration, and the acceleration is multiplied by the estimated mass to calculate the force of a kick.

There is one last benefit, the storage capacity of the brain is limited.

The memory capacity of the brain, calculated according to 10 billion neurons, is only 30 TB when it is fully calculated, which is the capacity of 30 hard disks according to the current regular server hard disk.

Not too much, but too little.

Anna's robot drawings cost 250 TB, which means that humans can't remember a robot drawings with all their brains.

At this moment, when the brain and the network are connected, the network becomes the backup hard disk of the brain.

Anna can use her brain as a root directory to get the server address from the index, and then call it from the server, which is simple and pleasant.

The storage capacity of the brain can theoretically be unlimited.

She can now memorize the shape of every landmark on every street in New York's five boroughs, not with her brain, but with extraction.

However, the brain circuit is much more complex than that of a computer, and the circuits of a CPU are simply copied and repeated, and then copied and repeated.

As for brain circuits, 10 billion neurons are organized in 10 billion ways.

If we talk about complexity and integration, the brain is far more than the current supercomputing.

Now Anna's brain has both the precision of a computer and the high degree of integration and complexity of the human brain.

Maybe this is what he calls a new human.
