Due to the extremely small target area of the plasma cutter, Wang Ye needed to burn as many regions as possible in one go. Even after a part was burned and necrotized to the point of exposing the bone, he had to endure the intense pain and continue burning other areas. While he was burning other areas, the previously burned and necrotized parts were quickly replenished with flesh and healed.

Therefore, after Wang Ye had burned and tempered his entire body in a circle, the starting point had basically healed, allowing him to seamlessly continue burning the second circle. Because the plasma cutter’s power consumption was terrifyingly high, consuming a degree of electricity per minute, and the total storage capacity of these few energy storage batteries was only a few dozen degrees, Wang Ye needed to frequently change the batteries. While he was using one battery, another could be charged using solar energy.

He maintained this high-intensity body tempering frequency throughout the morning. During this time, the heat consumption was almost unbelievably high every second since he constantly needed to recover numerous deep, bone-exposing injuries all over his body. The heat consumption per several seconds was approximately equivalent to an average person’s entire day’s calorie consumption, about two thousand calories. For a regularly built human with about 30% body fat, the energy stored in fat is at most around two hundred thousand calories. Even someone as strong as Wang Ye could only store around five hundred thousand calories, which would support his high-intensity training for only about twenty to thirty minutes without new energy supply.

If it weren’t for the continuous supply of energy from sunlight, Wang Ye might have starved to death despite gorging endlessly. Yet even with the energy from sunlight, he had recently started to feel somewhat overwhelmed.

After all, light is merely light; the upper limit of energy provision is still too low. Even solar panels have to rely on finding materials with broader light absorption range and higher light absorption coefficients to improve efficiency.

Thus, Wang Ye needed to start researching controlled nuclear fusion as soon as possible to achieve a once-and-for-all solution.

However, while tempering his body with the plasma cutter, a new idea suddenly emerged in Wang Ye’s mind as he looked at the energy storage batteries before him: absorbing the battery, or installing the battery in a certain part of the body to achieve continuous, large-scale energy supply. The current world’s battery technology is already excellent; a coin-sized nuclear battery can continuously supply energy for fifty years. Although the power of one is not high, a qualitative change can be achieved through quantity.

If Wang Ye could buy such nuclear batteries and find a way to install them in his body to supply continuous energy internally, he might be able to gain even stronger power than he currently has.

Even if he couldn’t buy such rare nuclear batteries, Wang Ye could use regular batteries to supply energy. Although ordinary batteries don’t have high storage, only lasting months or a year, they are enough for his current use.

This new idea opened a new world for Wang Ye.

He planned to stay at his hometown for some time to study how to use batteries for his energy supply, solving this problem as soon as possible. Otherwise, relying solely on sunlight for energy would eventually lead to issues.

Finally, nearing noon, Wang Ye was thoroughly exhausted.

But it wasn’t physical exhaustion; it was mental depletion.

The prolonged, intense pain had led his spirit into a state of fatigue.

This kind of mental exhaustion couldn’t be quickly recovered and could only improve slowly over time.

Meanwhile, the energy storage batteries he brought had completely drained their power.

Even with all these batteries, constantly being charged by solar energy, they could only provide two hours of energy, showcasing just how frighteningly energy-consuming the plasma cutter was.

In the industry, people even referred to the plasma cutter as an "electric tiger" due to its massive power consumption, where most construction sites wouldn’t use it for more than half an hour.

After tidying up the mess, Wang Ye took his things back home.

He had lunch with his parents and chatted for a while.

At two o’clock in the afternoon, Wang Ye returned to the unfinished building.

This time, he didn’t bring the plasma cutter but bought a few Nanfu batteries and dozens of boxes of toothpicks from the supermarket downstairs. He planned to start his first battery experiment this afternoon while also training his long-neglected Throwing Skill.

Wang Ye, maintaining the Bone Shrinking Skill, walked for twenty minutes to the morning’s training location.

He first took out the Nanfu batteries from his pocket, observing the battery before him while checking the battery operating principle on Baidu Encyclopedia.

Nanfu batteries could be considered the most famous batteries in China. The early advertisement slogan "one battery is better than six" made the manufacturing company rich and without competitors even today.

But in reality, with the development of dry battery technology in China over the years, most batteries’ quality is now roughly equivalent.

After thoroughly understanding the principles of dry batteries on Baidu, Wang Ye couldn’t help but bow his head in contemplation.

The principle of these dry batteries is that the chemical reaction inside the battery excites electrons, causing electron accumulation at the anode and generating an electron difference between the anode and cathode. When the battery is placed into an electrical appliance, the electrons accumulated at the anode flow into the cathode through the appliance’s circuit, providing power to the appliance during this process.

Batteries are designed this way because electrons can return to the battery’s cathode after passing through the circuit and flow back into the anode, maximizing the value of the electrons and allowing a single-use battery to last longer. 𝚏𝗿𝗲𝐞𝚠𝕖𝐛𝗻𝗼𝐯𝕖𝚕.𝚌𝗼𝗺

Therefore, battery usage highly depends on the circuit.

However, Wang Ye’s body doesn’t have a circuit. Constructing one inside his body is highly unrealistic, so he could only crudely replenish energy by absorbing electrons.

Currently, the simplest method seems to be directly swallowing the battery into his stomach.

Through the energy absorption function of his cells, he could absorb electrons from the battery and convert it into energy.

However, this approach also presents a problem: batteries are toxic,

containing primarily iron, zinc, manganese, and trace amounts of mercury, which is highly toxic. If a person experiences mercury poisoning, it can damage the central nervous system, with a mortality rate of up to 40%. Mercury can cross the blood-brain barrier and damage the central nervous system, causing headaches, insomnia, depression, anxiety, memory loss, tremors, and in severe cases, muscle spasms, coma, epilepsy, and other illnesses. A mere 0.1 milligrams can cause death.

An ordinary person swallowing a battery would either suffer from intestinal blockage or die from chemical element leakage toxicity.

Nowadays, Wang Ye’s stomach acid could dissolve most substances, and his resistance to poisoning exceeded that of a normal person by dozens of times. Thus, he wasn’t too worried about dying from mercury poisoning, and even if poisoned, he could recover quickly.

The current issue lay in whether he could use this method to extract electrons and provide energy to his cells. He didn’t expect a small battery to provide significant energy, as a Nanfu battery’s capacity is only fifteen hundred milliampere hours, translating to just 4-5 calories, less than a spoonful of oil. So this test was merely to prove whether he could extract energy from a battery.

If this could succeed and the side effects were minimal, the next step would be to test with higher capacity and density batteries.

After mentally preparing himself, Wang Ye swallowed a battery.
