Wang Zheng quickly grasped the key point: this world was different from the world of his previous life.

The turning point in history was in 2000, when a hole appeared in the sky above Antarctica. Wild animals began to mutate, and then human physiques were enhanced, with a few people even awakening powerful innate abilities.

While such changes pose a crisis for humanity, they also present an opportunity. Scientists have discovered through various studies that the source of all these anomalies is the hole in the sky.

One type of particle, invisible to the naked eye, was emitted, much like the blessed lands and grottoes described in ancient Chinese texts. Thus, the hole was officially named a grotto-heaven, and the emitted particles were called spiritual energy particles.

When the animal plague began, China had ample emergency plans for various disasters, its infrastructure construction speed was unparalleled, and the national government responded quickly, so it was only natural that it suffered the least damage.

The United States suffered heavy losses, and some government officials even shouted the slogan of "survival of the fittest," claiming that only the strong can survive, which makes people sigh.

Our old neighbor Russia was even bolder, launching a "Big Ivan" directly at the cave in the no-man's-land, but it had no effect. However, this style of doing things can only be praised: As expected of you, Mao!

As people in various countries began to awaken, they all realized that only the awakened could deal with the mutated beasts. So, the countries began to recruit various awakened individuals while also starting research on cave heavens and spiritual energy particles.

Some people have also hypothesized that there may be another world inside the cave, and have tried to trace the source of spiritual energy and enter the cave, but unfortunately they have been unable to enter no matter what.

The cave stands there in the air, visible to the naked eye, yet it seems to exist in a different dimension, impossible to touch. Airplanes and missiles can pass right through it without any abnormality.

Until the day the cave disappeared, no one or organization discovered its true secret. Since then, scientists have begun to shift their research focus to spiritual particles.

Research has shown that spiritual energy particles appearing in the sky can be passively absorbed by the human body. However, people's constitutions differ, and the amount absorbed varies. When the spiritual energy within the body reaches a certain level, it may mutate, giving rise to different abilities, which can be broadly categorized into several types:

Elemental: Controls natural elements such as water, fire, ice, wind, and thunder.

Superhuman: Enhances personal physique, passively increases physical attributes, or grants strength beyond physical limits.

Spiritual: Increases mental strength, telekinesis, and spiritual energy body, etc.

All humans born after the Reiki Age possess physical constitutions far exceeding those of ordinary people, yet very few are capable of awakening naturally.

Scientists then developed injectable Reiki gene serums. Once citizens reach the age of 16, they can choose whether or not to receive the serum. There is a 30% chance that injecting such a serum will awaken their talents.

This type of medicine can only be injected once in a lifetime, and it is only effective on people born in the Reiki era, because they have been passively absorbing Reiki since birth and their bodies have a corresponding compatibility.

Before the Reiki era, anyone who received this injection would invariably experience irreversible negative effects on their body, leading to a comprehensive decline in bodily functions, severe maladaptation, or even death from body explosion. Therefore, the government strictly controls this, establishing a dedicated department to prohibit such drugs from entering the market.

For people in the Reiki era, this is a chance to achieve instant success, with no side effects on the human body and at least an improvement in their physical constitution.

This brings us to the difference between drug-induced awakening and natural awakening.

The state sets unified standards to differentiate the level of superpowers based on the spiritual energy contained in the human body. The higher the spiritual energy value, the stronger the effect of using superpowers, and the more times they can be used.

The spiritual energy value is divided into several levels, FA, but the specific distinctions between spiritual energy values ​​are not specified. However, this is just a history book after all, and it is already a blessing that it has such detailed information. Wang Zheng did not pay too much attention to it.

The total amount of spiritual energy in an individual's body determines their control and use of innate abilities. Naturally awakened ability users can continuously grow, and can at least reach Rank B.

Those who awaken their abilities through drugs are not unable to improve, but the process is very difficult. They need to constantly break through their own limits and continuously squeeze out their potential. Even so, it is difficult to keep up with the speed at which naturally awakened individuals become stronger.

In short, those who are naturally awakened have better talent and greater potential!

Naturally awakened individuals are extremely rare in this day and age, which is why several classmates came out to refute Curly's claim that Wang Zheng might be a naturally awakened individual.

Wang Zheng sighed deeply. He was extremely unwilling to come to this dangerous world, but it was already a fait accompli, and there was nothing he could do but take it one step at a time.

"System? Cheat code? Open Sesame? Avada Kedavra?" After waiting for a long time, Wang Zheng realized that even the air in the classroom had become silent. He slowly shook his head. It seemed that there was no cheat code. What happened to the standard equipment for transmigrators?

Wang Zheng then walked towards the playground and headed towards his class's meeting point. When he arrived at the playground, he didn't see the physical education teacher. Instead, he saw that his classmates had already dispersed. Some were running laps, some were playing ball, and the disciplined ones were lifting weights.

After a few simple warm-up exercises, Wang Zheng started running. He ran faster and faster, and after working up a sweat, he realized that his current physical condition was far superior to that of professional athletes from his previous life. He timed himself and ran a few meters in his head, finishing in about 10 seconds for 100 meters. He wondered what level he would be at in school.
