Chapter 86

Wang Qi sat cross-legged on the ground outside the storeroom of the Immortal Academy, his hands resting on his legs, holding a piece of mixed red copper, his eyes tightly closed, as if sensing something.

Not far away, Mao Zimiao was biting the end of her pen, secretly glancing at Wang Qi from the corner of her eye.

Su Junyu, who was sitting beside them, did not take his attention away from the scroll of stories in his hand, but he raised his hand and snapped his fingers. With a *snap*, a red mark appeared on Mao Zimiao's forehead.

"Focus on your problems, don't look at that boy."

Mao Zimiao's face turned red as she defended herself: "I wasn't peeking at Xiao Qi!"

Su Junyu raised an eyebrow: "How many problems have you solved?"

Mao Zimiao's confidence wavered, and she stammered: "I... haven't solved any."

Su Junyu shook his head helplessly: "Mathematics is indeed the foundation of all methods, and all modern methods are inseparable from mathematics, which is also true. But, girl, you're taking the exam for Spirit Beast Mountain! You should be finding a teaching assistant from Heavenly Spirit Ridge to catch up on the Way of Living Beings!"

Mao Zimiao looked somewhat depressed: "I just wanted to..."

"Spring is long gone, okay..." Su Junyu muttered, then continued reading his stories.

By now, it was already night, and all the day's classes at the Immortal Academy had ended. Under a floating glass lamp, Wang Qi and Mao Zimiao were practicing the tasks assigned by Su Junyu.

A month had passed since the Xinshan earthquake. Due to his excellent performance in the battle against the Thunder Deer King and the Qi Accumulation Stage Ghost-faced Ape, Wang Qi was awarded fifty-six merit points. Apart from spending over thirty points to exchange for the borrowing rights of the first volume of the *Songting Collection*, Wang Qi did not exchange for anything else. For this month, he had been focusing on consolidating his foundation and learning the "Theory of the Essence of Spirit Qi" mentioned by Xi Boche in advance with Su Junyu and Xiang Qi.

And Su Junyu did not go back on his word. When the four who participated in the trial came to him for guidance, he never refused.

Wang Qi and Mao Zimiao took advantage of the evening to seek his help with their math problems.

The reason Wang Qi was sensing the mixed red copper was because it was part of his problem.

Mixed red copper is a common material used in alchemy, suitable for forging weapons for Qi Accumulation and Foundation Establishment cultivators. This material is so common that even alchemy masters can't do much with it. Wang Qi had been sensing this material for a long time.

Suddenly, Wang Qi leaped up, rushed to the prepared paper and pen, and wrote down a long string of numbers, then plugged them into a formula for calculation.

What he was calculating was known in the Divine Continent as the intrinsic formula of spirit qi. To be precise, he was calculating the intrinsic transformation formula of the mixed red copper.

The Immortal Dao of the Divine Continent has a direct understanding of the essence of matter, mass, energy, and spirit qi. In the eyes of modern cultivators, spirit qi is no longer an indescribable substance that can only be perceived through inspiration or qi sense, but a quantifiable existence.

When Wang Qi read the books given by Li Zeyi in Dabai Village, he noticed that the physical laws of the Divine Continent were terrifyingly similar to those of Earth. This similarity was not limited to the basic levels of mechanics and thermodynamics but extended to all aspects. Both worlds have molecules and atoms, energy exchanges are discontinuous, and the uncertainty principle applies at a certain scale. According to the Heavenly Song Heavenly Primordial Group and the Great Elephant Phase Wave Art, this world also has wave-particle duality, and the speed of light is still the upper limit of speed. In more fundamental fields, the four fundamental forces still exist, gravity is still caused by the curvature of spacetime due to mass, and mass and energy can still be converted into each other.

So, what caused the appearance of cultivators, the Immortal Dao, the demon beasts, and all sorts of incredible beings in the Divine Continent?

It's because of "spirit qi," a physical quantity that does not exist in the universe where Earth is located.

Similar to the scientific community on Earth, the Immortal Dao of the Divine Continent also regards matter as the foundation. Mass is a physical property of matter, representing the amount of matter. Energy is another property of matter, representing the degree of change in the movement of matter. Space can be represented as the existence of matter, and time can be represented as the movement of matter.

In such a system, "spirit qi" is considered an exponent of energy.

If the mass-energy formula of the Divine Continent were expressed in Earth's mathematical language, it would be E^spirit qi = mc^2.

If this formula were shown to Earth scientists, it would likely be considered a prank. Even Wang Qi, who had already experienced the wonders of spirit qi, had a "What the hell are you playing at?" expression when he first saw this formula.

The reason is simple: in the universe where Earth is located, the "exponent of energy" is a constant, always equal to one.

In the Divine Continent, spirit qi is a variable, a quantity that fluctuates slightly around one under normal circumstances.

And the amazing thing is that spirit qi is closely related to ordered complex systems. The higher the order and complexity of a system, the more spirit qi it can contain and circulate. The most complex known ordered system is "consciousness," which allows humans to cultivate, and the demon races to open their spirits as the first step in cultivation.

It is also because of this that spirit qi flows between celestial bodies; ecosystems can gather spirit qi, giving birth to demon beasts and spirit plants; the planet of the Divine Continent can exchange spirit qi with the void, thus the existence of the breath of heaven and earth.

And the so-called "attributes of spirit qi" are actually the external manifestations of different intrinsic formulas. The neutralization of two types of spirit qi generally means that the sum of their intrinsic formulas equals one, so the phenomena of spirit qi cancel each other out after neutralization. The mutual suppression of spirit qi means that when two types of spirit qi meet, one's intrinsic formula can "cancel out" the other.

All magical phenomena can be explained by this theory of the essence of spirit qi!

Because Wang Qi was not yet accustomed to the calculation symbols of the Divine Continent, his calculations were not very fast. Su Junyu shook his head as he watched.

However, the calculations were not complicated. Soon, Wang Qi derived a function. He handed the simplified formula and the mixed red copper to Su Junyu.

Su Junyu closed his eyes and sensed the spirit qi in the mixed red copper for a moment, then looked at the function Wang Qi derived and nodded: "Not bad, the transformation formula derived from the typical metal experience formula."

Wang Qi's expression remained unchanged, but Mao Zimiao beamed with joy.

"However, this can be further simplified," Su Junyu continued: "We can start the next step of learning now."

Wang Qi nodded. He actually knew that the formula he submitted was not the simplest. However, it was better not to reveal some content that Su Junyu thought he hadn't learned yet.

Su Junyu called Wang Qi over, and a new round of teaching began.
