Energy Stone

Biodata

Properties

Energy Stones are small, irregular, crystal-clear stones approximately the size of a thumb. Their energy is condensed within the crystal, producing an intense instinctive attraction in Wang Tianyu when he first encounters one. 11

• When absorbed, an Energy Stone releases a warm current through the user's body before becoming white, non-luminous powder. 19
• The powdered residue is not unique to Wang Tianyu's system; Energy Stones naturally become powder after their energy is depleted by human absorption. 141
• Energy Stones contain universal energy and can be used by both humanity and Martial Artists of the Otherworld. 147
• Wang Tianyu's system must physically contact a stone to absorb it; stones still embedded in mine rock cannot be converted until extracted. 310

Grades and Cultivation Compatibility

Uses

Cultivation Resource

Martial Artists can directly absorb Energy Stones to cultivate, though doing so is slower than using energy processed through an array. Arrays are expensive to construct and waste considerable energy during decomposition. 277

• Energy Stone-powered formations can break down stones and distribute their energy through a cultivation facility, raising ambient energy density. 233
• Sichuan First Martial University's cultivation room uses mid-grade Energy Stones to support Martial Ancestor-level cultivation. 277
• Wang Tianyu treats stones as direct strength because his system converts them immediately into Energy Points rather than merely accelerating normal cultivation. 218

Currency and Trade

Energy Stones function as hard currency among Martial Artists and are the primary currency of the Otherworld. 147 323

• Su Pengfei values each Energy Stone at 100,000 during his wager with Wang Tianyu's class. 12
• Martial Arts universities exchange school points for Energy Stones, pills, equipment, and cultivation techniques through internal trade networks. 52
• Low-grade Energy Stones are used for rewards, wagers, and even arena admission fees. 193 244 262
• Mid-grade and top-grade stones are used in increasingly large transactions, including auctions and rewards for high-rank Martial Artists. 392 419 490

Energy Stone Veins

Energy Stone veins are strategically vital mining sites, usually protected by fortifications and high-rank Martial Artists. Humanity's own veins are extremely rare and kept secret, while the Otherworld possesses comparatively more deposits. 295 308

• A vein consists of Energy Stones embedded within a hard, energy-absorbing core rock layer. 310 311
• As long as the core rock remains intact, it absorbs surrounding energy and continuously produces new Energy Stones, making the mine renewable. 311
• Mining normally avoids excessive damage to the core rock; destroying the layer above it changes the vein's structure, softens the rock, and sacrifices its regenerative ability for rapid extraction. 311 312
• Larger veins contain more stones and generally produce higher-quality grades. 313
• A medium-sized top-grade vein can yield an estimated 500,000 to 1,000,000 top-grade Energy Stones, alongside millions of low- and mid-grade stones. 479

Captured Otherworld Vein

Wang Tianyu's task squad captured an Otherworld Energy Stone mine during the City-Breaking Operation. The mine was defended as a fortress spanning several kilometers and guarded by Martial Ancestors. 300 308

• The squad found dense deposits of low-grade Energy Stones and scattered mid-grade stones within pale-blue, glowing rock. 310
• Following Chu He's mining advice, Wang Tianyu split the core vein with repeated blade radiance strikes, allowing the squad to mine it quickly. 311 312
• The operation extracted over two million low-grade Energy Stones and 40,000 mid-grade Energy Stones from a small vein. 313
• Wang Tianyu later received 50,021 mid-grade Energy Stones after his rewards and spoils were converted into resources. 323

Story Role

• Su Pengfei uses an Energy Stone to establish a twenty-stone wager against Gao Bin, introducing Wang Tianyu to the resource and motivating him to secure the reward. 11
• After Wang Tianyu wins the student match, Su Pengfei gives him ten Energy Stones as his share of the wager. 18
• Wang Tianyu verifies that the system absorbs the stones and gains Energy Points, choosing to use them for cultivation rather than sell them. 19
• Upon entering the Martial Ancestor Realm, Wang Tianyu discovers that low-grade stones no longer work with his system and begins seeking mid-grade stones instead. 234
• At the Half-Step Martial King Realm, his system changes again to require top-grade Energy Stones. 419
• After reaching the Martial King Realm, even top-grade Energy Stones can no longer advance his system; Origin Stones become the required higher-level resource. 565 571
