　　After a lot of thinking, Richard has a guess that the so-called "highly activated state" is likely to be the "energized state".

　　In normal human body, the cells in the body carry out metabolism and nerve signal transmission, which are accompanied by the flow of potassium and sodium ions on the cell membrane, thereby generating bioelectricity. This kind of bioelectricity is very weak, and the voltage is generally in the order of millivolts (millivolts are mV, and 1 volt is equal to 1000 millivolts).

　　Although it is weak, bioelectricity is of great significance to people. Its changes can directly lead to changes in cell metabolism or function in the body. For example, when nerve fibers are locally stimulated, the excitability at the cathode will increase and the membrane potential will decrease (depolarization), and the excitability at the anode will decrease and the membrane potential will increase (hyperpolarization).

　　According to the description of the method of constructing the source of the law in the chapter of Monroe, it is obvious that some kind of transformation of the body structure is made. Among them, the so-called spiritual power is used, which is most likely related to this bioelectricity. Perhaps it is to increase the biological current in the human body to a certain extent, so that the body can open up a new "organ" under the action of mental power.

　　 Of course, this is just a guess, right or wrong to be verified.

　　 The main reason for Richard to call the two maids is to prepare for a test that can produce a battery that can discharge current in the current Middle Ages, which has nothing to do with "electrification".

　　 First, Richard prepares to make the simplest fruit battery. The raw material only needs a piece of copper, a piece of zinc, a piece of metal wire and a fruit.

　　Because the active types of the two metals, copper and zinc, are different, after inserting the fruit, the zinc flakes will undergo an oxidation reaction, losing electrons and flowing to the copper flakes, thereby generating current in the metal wire.

　　Because there is no difficulty, Richard simply said a few words and asked the maid Angel to make it. The other party did not disappoint Li Cha. Soon after the production was completed, he saw a thin iron wire connected to a nail-sized copper and zinc sheet, inserted on a pear.

　　Angel, the maid, carefully handed the fruit battery to Li Cha. After touching it, Li Cha frowned and immediately knew that the fruit battery was unqualified.

　　 is not a problem of production. After all, the production method is so simple that it is impossible to make mistakes, but the problem of the fruit itself. Because the fruit juice is acidic, the chemical reaction can be successfully carried out, thereby generating electric current. But compared to real acid, the acidity of fruit juice is still too weak, so the current and voltage generated are too small.

　　 Richard felt it. It was estimated that the voltage was less than 0.5 volts and the current was less than 1 milliampere. This level of current is stronger than the normal biological current of the human body, but it is too reluctant to want to affect the internal body of the body.

　　After all, there is resistance in the human body. If the biological current is increased spontaneously in the body, naturally there is nothing, but a normal person without the talent of a wizard is impossible to do. If you want to apply current from the outside to affect the body and use scientific methods to crack the remodeling of life, then you must overcome the resistance of the human body up to more than 1000Ω, and you must apply a stronger current.

　　 The question now is, how to get a stronger current?

　　 Richard frowned, thinking for a few seconds, and began to ask the two maids to make different fruit batteries.

　　Different types of fruit, the acidity of the juice is also different, then the current generated is divided into strong and weak, find the strongest one, may ignore the body's resistance of more than 1000Ω, to meet the requirements.

Medieval fruits are not rare when counted. Common ones are cherries, strawberries, blackberries, apples, pears, cherries, plums, grapes, plums, currants, mulberries, black prunes, figs, and sea. Jujube, lime, lemon and other dozens.

　　Richard ordered that some people prepared these fruits naturally. Not many times, except for some that are not mature due to seasonal reasons, the rest are placed on the experimental table.

　　Richard waved his hand, and Angel and Luna two maids quickly made it. In a short time, various types of fruit batteries were placed on the table in left and right rows, with Angel on the left and Luna on the right. Obviously, Angel made more.

　　Richard did not comment much. He reached for a fruit battery and tested it with his body. After a while, he put it down and picked up another one.

　　 Repeated so many times, after testing all the fruit batteries, Richard already knew. Because of the different acidity of the fruits, some of these fruits emit more current than the original pears, such as apples, such as gooseberries. The strongest is lemon, but even so, the voltage is just over 0.5 volts and the current is just over 1 milliampere.

　　 Under normal circumstances, the average current for an adult male to cause sensation is about 1.01mA. That is to say, under the influence of human body resistance, this level of current has just made an ordinary person aware.

　　 This is not what Richard wanted.

　　 Licha stood frowning deeply in the laboratory. The two maids looked at Li Cha's solemn expression and did not dare to breathe at the same glance, bowing their heads carefully. Although they are well aware that His Royal Highness will not lose his temper casually, nor will he punish people for no reason, but His Royal Highness is not always a good thing.

　　Richard did not know what the two maids were thinking, but continued to think seriously about how to solve the problem.

　　How to get stronger current?

　　 Maybe use other plants than fruits to make batteries, UU reading www.uukanshu.com can give it a try. For example, the famous potato clock is made of potatoes.

　　 But... it seems that there are no potatoes in the Middle Ages.

　　After all, according to the development on modern earth, it wasn't until the great nautical era after the Middle Ages that someone spread potatoes from South America to Europe.

　　 In the current medieval-like world, Richard cannot determine whether it is the one in the history of the earth or whether there is so-called South America and Europe. But it’s true that no potatoes are used, so it’s not necessary to think about potato clocks.

　　 Having said that, even if the potato clock is actually made, there is a high probability that it may be a waste product. After all, in order to ensure normal growth of plants, the acidity cannot be too strong. It is very possible to try all the plants in the current world, and the current produced by the manufactured battery is only in the same range.

In this case……

　　 Richard's eyes narrowed and flashed quickly.

　　Since this is the case, you can only make real batteries, such as voltaic stacks.

The 　　 Volta stack is the first recorded power generator in the history of modern earth. It was invented by the Italian Volta on March 20, 1800. The structure is slightly more complicated than the fruit battery, but it is not too difficult. The key is the preparation of materials.

　　 Since this is the case, then...

Richard turned his head to look at the two maids quickly and issued a command: "Angie, you go to configure some salt water, the concentration is moderate. Luna, you come with me, trim these linens to the same size. Then put these fruit batteries in Treat the copper and zinc sheets and cut them into a ring..."

　　After Richard finished speaking, the two maids quickly began to get busy.

　　Few times, the materials are ready, Richard began to make voltaic stacks himself on the experimental table.
