Soon, Richard came back with more rats and began to design experiments, conducting control tests, control variable tests, and repeat tests.

Eventually, Richard discovered that some of the situations were a little more complicated than he had imagined.

For example, the performance of mice is not only the reinforcement of fear signals, but more accurately, the acceleration of nerve signal transmission. To put it simply, the little mouse reacts faster and can respond to external stimuli in a shorter time, so it can constantly dodge the attack of the scalpel.

Richard wasn't sure what the rationale was, but it was much more important than the "one-eyed fury potion".

In other words, the dark blue extract in the blood of the "Griffin Colorful Bird", which is regarded as an impurity by One-Eyed, is not an impurity at all, but a treasure, and is worth more than the entire "One-Eyed Rage Elixir".

Improves reaction speed!

This is not just a difference of one or two points, but sometimes it can play a crushing role.

It's like the difference between 59 points and 60 points, and the difference between 99 points and 100 points, representing two worlds.

Generally speaking, the nerve signal transmission in the human body is almost at the level of 100 m/s, which leads to a certain delay in the body to make a move even if the brain reacts to something.

Therefore, all explosive actions must have a time to initiate and react.

For example, in sprint races on modern earth, from the referee firing the flare gun to the athlete's start, the process must exceed 0.1 seconds, which is the reaction limit time obtained through scientific calculations. If the start is less than 0.1 seconds, then it will be directly judged as a rush and disqualified.

What if you reduce the time to initiate and react, say by a fifth, a third, or even a half?

It's going to be scary.

In combat, especially in hand-to-hand combat, sometimes a move can determine the outcome of a move that is fast on the line, so if each action can be half as fast as the enemy, it is completely teasing.

"How does this dark blue extract from blood work? How does it speed up nerve transmission?" Richard's eyes flickered, and he guessed, "Covering the 'Lang Fei node' to speed up the transmission of nerve fibers, or does it change the transmission process of neurotransmitters?"

Generally speaking, nerve signaling in the human body is transmitted by nerve fibers, which are made up of multiple neuronal cells. A neuronal cell can be divided into two parts: the cell body and the neurite according to the structure. Neurites are further divided into two types: dendrites and axons. According to the function, neuronal cells can be divided into four parts: the receiving area, the trigger area, the conduction area and the output area.

When a nerve cell receives a signal or stimulus from another cell, the trigger zone (dendrite) first generates an action potential, which is quickly transmitted through the conduction zone (axon) to the output zone (axon terminal).

The output region synthesizes the neurotransmitter and encapsulates it within the synaptic vesicle to diffuse the neurotransmitter molecule to the receiving region (dendrite) of the next neuronal cell.

The receptor in the receptive zone of the next neuronal cell binds to the neurotransmitter and produces a biochemical reaction, which in turn causes an action potential to appear in the trigger zone of the next neuron, which continuously transmits the signal.

To speed up the transmission of nerve speed, in general, there are only two ways.

First, speed up the process of the "conduction zone".

Second, speed up the process from the "output zone" to the next neuronal cell "receptive zone".

The first method is to achieve this, and then the best way is to reduce the weakening of the signal, which vertebrates have a great advantage of.

As you can imagine, the entire nerve is connected by segments of wires (neuronal cells), and the signal strength weakens when the current signal flows through a section of wire. The cheating of vertebrates over other creatures is that they put a shameless insulating shell on the wire, called the myelin sheath, which ensures that the signal strength weakens very little and can be transmitted more quickly.

However, the problem is that the myelin sheath is not very tight, and there is a gap in the middle, which is section by section if you look at it with a microscope, and the gap between the nodes is called the "Langfei's node", and the wires (axons) in the "Langfei's node" are still exposed. If the number of "Lang Fei knots" decreases, then the wires (nerve axons) will be less exposed and the faster the signal will be transmitted.

The second way to achieve this is to change the way neurotransmitters are delivered. Because the transmission of this process is divided into many steps such as producing neurotransmitters, wrapping, diffusion, receiving, binding, and reacting, which is extremely cumbersome. If it can be optimized, even if it is only one step of optimization, the degree of acceleration is great when you look at the transmission of thousands of neuronal cells.

So how does the dark blue fluid work, and what is the way to speed up the nerve reactions?

Richard's eyes twinkled, he thought quickly, and finally decided to test it out for himself.

Taking a deep breath, Richard picked up the configuration of "Richard's Unknown Elixir" and took a sip, closed his eyes, and carefully perceived the change, and after a while, he took another sip, raised the dose and continued to perceive, deeply perceive, and invoke spiritual power to perceive.

The change occurred, and Richard's brow furrowed slightly.

Halfway through, Richard furrowed his brows, opened his eyes, his eyes flashed brightly, looked at his hands, and said to himself, "Is that so......?"

In Richard's perception, speeding up neural transmission is not the first method at all, nor the second method, but the third method beyond cognition.

Theoretically, as long as the signal is successfully transmitted, the brain can react, and the brain's response signal is transmitted to the corresponding part, it does not matter the process.

After countless years of development, the entire animal kingdom has evolved a perfect nervous system for this function, which includes large and small structures, which are precise and complex.

But...... What if you abandon this system?

It's like, transporting a bunch of things, a whole complete railway system has been developed, which is efficient, but at the same time efficient, it also limits further development. If the rail system were abandoned, wouldn't it be better to use airplanes for air transport?

Richard is not entirely sure, but there is some vague speculation that the reason for the speed of nerve reflexes accelerated by the agent is probably not due to the transmission of electrical signals from neuronal cells, but to the generation of a special substance to transmit signals.

This substance does not exist on the modern earth, and is like a specialty of the current world, similar to a free energy element.

Free energy elements can run along the channels (blood vessels, nerves) in the human body to reach a specific state, and then excite and release them outside the body to play a role.

The special substance produced can also run along the human channel, attached to the nerve but not completely bound by the nerve, it can find the shortest and fastest path, transmit it to the brain at a speed beyond the nerve signal, and then return the signal.

It can be simply understood that the nerve is an ordinary broadband line, buried deep in the ground (in the body), and the speed of this broadband line is okay, but it is not too fast, and there is a certain delay. After that, it was transformed, and along the line buried by the nerve, a new fiber broadband was buried, and the speed was greatly improved, so fast that it exploded, and the delay was greatly reduced.

Although this fiber optic line is temporary, it requires a potion to appear, and it has a certain duration, which is costly, and it is impossible to use it all the time in daily life. But in the course of the duration, if used properly, it can exert unimaginable effects.

Unbelievable results!
