Wang Ye nodded, after eating, he sat on the sofa and watched TV with his parents for a while before continuing his training.

His current schedule mainly involves training in Throwing, Vajra Indestructible, and Bone Shrinking Skill during the day,

while at night, he focuses on training Running, running continuously from seven in the evening until seven the next morning.

Running continuously for twelve hours.

During this period, Wang Ye did not use a watch to record mileage, because his current running speed was simply too fast, most of the time even the watch’s GPS couldn’t keep up with his speed.

However, according to his current average speed of 400 kilometers per hour, he could roughly estimate that he ran five to six thousand kilometers, which is roughly a round trip distance within China.

The next day, Wang Ye received good news.

The desktop spectrometer he ordered had arrived.

Upon receiving this news, Wang Ye was overwhelmed with excitement.

He immediately ran to the villa area.

When he opened the door, he saw the desktop spectrometer being installed by workers in the corner of the living room,

The main body of the spectrometer was about the size of a computer case, connected to a computer display screen nearby.

The computer featured a large amount of complex data display fields, with sidebars mostly labeled in English or shorthand, such as Fe representing the element iron, Cr representing chromium, beneath which precise values to five decimal places were displayed. Without specialized knowledge, someone unfamiliar would definitely not know how to operate it.

This device is actually an experimental instrument for measuring spectra, used for analyzing metal material components, detecting chemical reactions, and studying material properties, among others.

It is mainly used in scientific research, medical fields, and the steel industry. In the fields of physics, chemistry, and materials science, spectrometers are widely used for atomic and molecular structure analysis, material quality analysis, infrared spectrum analysis, surface analysis, and so on. It is also possible to identify various diseases and pathological changes by analyzing the spectral information of human tissues and body fluids. For example, near-infrared spectroscopy can detect tumors, blood, and brain function abnormalities. In addition, it can be used for environmental monitoring by analyzing pollutants in the atmosphere, water, soil, etc. for environmental pollution monitoring and analysis.

Some scrap recycling businessmen buy handheld spectrometers to sort precious metals in scraps and sell them at high prices.

Most handheld spectrometers are only the size of a kettle, but their prices almost always exceed two to three hundred thousand dollars, not much cheaper than desktop spectrometers. The main reason most scrap recycling businessmen and researchers purchase such expensive handheld spectrometers is for convenience, as they can scan things at any time, while desktop ones have to be fixed in place, requiring samples to be cut and placed at the detection port for scanning, and are also more complex to operate.

The main reason Wang Ye bought it back was to test his current bone composition. His bones had become so hard, they were clearly no longer purely calcium, but some kind of special alloy material.

Additionally, most of his other body tissues had also changed in composition, which he could feel himself. It wasn’t just a change in density, because density is an inherent property of a substance, and once bone calcium density increased to a certain level, it wouldn’t increase further unless its nature changed, for example, changing from calcium to iron.

Moreover, his way of nutrient intake had also changed. Before coming home, he hadn’t eaten normally for a long time nor absorbed a lot of calcium. If most of his bones were made of calcium, he would have long since collapsed due to osteoporosis.

But to conclude that his bones had turned into metal also seemed unreasonable, as Wang Ye hadn’t deliberately ingested any other metallic elements. His main means of energy replenishment now was absorbing ultraviolet light, at most absorbing some metal particles in the air while breathing.

For example, iron, aluminum, magnesium, and others. These particles come from soil, rocks, minerals, released into the air through natural processes like weathering and erosion. Additionally, industries like smelting, mining, and chemical production also produce large amounts of metal particles. These particles are emitted into the air in aerosol or smoke form, such as lead, zinc, copper, mercury, etc. Automobile exhaust emissions, road wear, and brake pad wear also produce metal particles, like iron, chromium, lead, etc. These particles accumulate in the air near cities and roads.

But the gram amount of these metal particles is really too little, even if exposed to these pollution sources for a whole day, it wouldn’t absorb even more than a gram of metal elements. However, if Wang Ye’s body, like a vacuum cleaner, naturally absorbed a large number of metal particles during this evolutionary period, it might change the elemental composition of his body.

In summary, relying on the spectrometer for detection is the only way to know the result.

Wang Ye referred to the spectrometer in front of him, searching online for video tutorials on how to operate a desktop spectrometer. After about ten minutes of watching, he barely understood the basic operation of this desktop spectrometer.

Unlike handheld spectrometers that only require a button press to scan a sample and get results, these desktop spectrometers require placing the sample at the detection port for multiple tests, obtaining multiple data sets, and calculating the average value, then comparing against the standard values of other metals to determine which metal the sample material tends toward. Therefore, the accuracy of desktop spectrometers is much higher than handheld ones because it calculates the average of multiple data sets, with fewer errors and a lower failure rate.

Wang Ye sat in front of the screen, casually broke off a piece of stainless steel on the furniture, and experimented by placing it in front of the testing port. He operated the computer with the mouse while fiddling with the piece of stainless steel in front of the testing port. Approximately two minutes later, the analysis results of this piece of stainless steel appeared on the screen.

According to the analysis results, the sample primarily contained elements like iron, carbon, chromium, nickel, with iron having the highest content, exceeding 70%, and other element contents being relatively low. 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞

"Quite convenient," Wang Ye couldn’t help but praise.

He originally thought operating this thing would take at least half an hour, but didn’t expect it to be resolved in just two minutes.

After thoroughly understanding the operation process of detection analysis, Wang Ye began thinking about how he should test his own bones.

Obviously, putting a hand directly on the detection port wouldn’t work, knowing that any impurities or obstructions would affect the spectrometer’s results, even cautious people clean a sample with alcohol before testing.

Therefore, to obtain the most accurate test results, Wang Ye had to break one of his bones, clean off any remaining flesh and blood on the surface, and place it on the device for testing.

After hesitating for a moment, Wang Ye selected a section of his pinky finger.

He gripped his right pinky tightly with his left hand and suddenly exerted force.

Crack!!!

A cracking sound exploded, and his pinky was forcibly snapped.

Even the battle-hardened Wang Ye couldn’t help but bare his teeth in pain at this moment.

The feeling of breaking a finger is indeed excruciatingly painful.

But after the pinky was snapped, the fracture rapidly showed signs of recovery.

Masses of flesh wriggled, quickly staunching the flow of blood.

Wang Ye squinted his eyes, intently watching the broken surface of the pinky. He wanted to see whether the fracture would heal directly or a new bone section would grow. You should know, if a human limb is severed, without timely reconnection, it remains in a state of amputation for the rest of life, only creatures like lizards and salamanders can regrow new bones after a fracture.

The reason is that the human structure is too complex and the body is too large, making limb regeneration extremely energy-intensive, and hence, impossible. For instance, the Komodo dragon, despite being a lizard species, cannot regenerate limbs because of its excessive size.

But now, with Wang Ye’s body having sufficient energy stored and his central nervous system under full control, is limb regeneration now possible?
