79: Sequence 017: Thunderwood

In Underground Mo City, the chill of energy shortages had not yet fully faded, but a new, vibrant restlessness had quietly replaced the previous silence.

Inside the cavern where the demonic liquid assembly line was located, the roaring sound remained low, but it now carried a rhythm that was different from before—smoother and more stable.

The air was no longer filled with that suffocating, cloying sweetness, but rather with the unique, elegant fragrance of emerald spirit dew, a mixture of fresh vegetation and the cold crispness of jade.

Barrels of emerald spirit dew, warm as jade and containing inner radiance, were produced, prioritized for repairing the damage to the Thunderstorm Worker Bees and replenishing the Origin Qi consumed by the Vajra Battalion soldiers.

The effects were immediate; the entire Sequence Legion of Mo City was like parched earth meeting sweet rain. The listlessness was swept away, and their overall presence was even more refined than before the battle.

However, Mo Yuan's gaze had long been cast into the deeper depths.

Passive defense and repairs were far from enough; what he needed was... expansion, absolute control!

After enduring the siege of the corpse tide and the energy crisis, the defense system of Underground Mo City appeared thin and passive.

Although the Nine Heavens Thunder Hell Formation was powerful, it required energy to drive it and lacked spiritual intelligence.

He needed a living line of defense that could fight autonomously, consume less energy, and even self-repair!

His gaze fell upon the edge of Mo City, on those Green Vine Demons that were rooted in the rock walls and tunnel junctions like loyal guards, silently reinforcing the structure with their tough vines.

These low-level demonic plants had tenacious vitality and extreme plasticity, making them the perfect experimental base.

Target... Green Vine Demon mother plant...

Infuse... emerald spirit dew... maximum dosage...

Guide... metamorphosis into Thunder Wood...

The cold order was issued.

A team of Vajra Battalion soldiers carefully carried a barrel of the highest concentration of emerald spirit dew to the entrance of the main tunnel on the west side of Mo City.

Here, the main root of the thickest, most dense Green Vine Demon mother plant was coiled. Its dark green vines, like a web of giant pythons, covered the rock walls for dozens of zhang, serving as the primary reinforcement for the structure here.

Pour!

The emerald spirit dew, thick as paste and radiating strong vitality and gentle energy, was slowly poured onto the thick, exposed roots of the Green Vine Demon.

Sizzle... There was no violent conflict, only a kind of... greedy sucking!

The Green Vine Demon's dark green vines suddenly lit up!

Like a desert in a long drought encountering sweet spring water, it devoured the emerald spirit dew at an astonishing speed!

The pure life energy and gentle catalytic power within the spirit dew were an unprecedented tonic for it!

Its body began to grow wildly at a speed visible to the naked eye!

The main vine swelled violently, expanding from the thickness of a bucket to the size of a millstone!

The rough bark on the surface cracked, revealing the newly formed wooden layer underneath, which had the translucent luster of emerald!

Countless new branch vines burst out, like dancing giant pythons, drilling even more frantically into the rock layers and spreading in all directions!

Its root system dug deep downwards, even piercing directly into the remains of the nearly exhausted Thunder Crystal Mine underground, instinctively drawing in the residual, thin thunder energy within!

But this was not enough!

Inject... Thunder Rune Dao Seed!

Mo Yuan's consciousness locked onto the core of the Green Vine Demon, and he pointed his Thunder God Arm from a distance!

Sizzle! A cyan-gold thunder rune, condensed from Eternal Life Thunder Strength and containing the dual Dao Rhyme of vitality and destruction, was forcibly driven into the deep, core wood of the wildly growing Green Vine Demon like a seed!

Roar!!!

For the first time, the Green Vine Demon let out a beast-like screech, mixed with both pain and pleasure!

Its entire massive body began to tremble violently!

The thunder rune exploded within its body!

The violent thunder strength merged frantically with the vitality of the spirit dew it had devoured and the thin thunder energy it had drawn from the mine remains!

The metamorphosis had begun!

On its newly formed emerald wooden layer, countless naturally generated, profound, and complex dark gold thunder patterns began to appear!

These patterns spread rapidly like circuit boards, covering all the newly grown branches and vines!

Its leaves became narrow and sharp, their edges glinting with a metallic cold light. What flowed through the leaf veins was no longer sap, but dense, cyan-gold electric arcs!

Most astonishingly, at the top of its main trunk and at the ends of several major vines, huge bud-like structures began to swell. The surface of the buds was covered with scales that were a Fusion of wood and metal, containing heart-stopping thunder energy within!

Its aura climbed step by step, leaping from its original status as a low-level demonic plant, breaking through the Bottleneck, and reaching a level comparable to a Foundation Establishment Stage Cultivator!

Moreover, what it emitted was no longer pure Demonic Qi of vegetation, but a strange pressure mixed with boundless vitality, tough wood, and violent thunder!

[sequence 017: Thunder Wood Demon]! Born!

But this was not the end!

This was only the first one!

Continue! All Green Vine Demons at key nodes... synchronize the transformation!

The order was given, and the Vajra Battalion soldiers, who had been prepared long ago, poured barrels of emerald spirit dew onto the roots of the Green Vine Demons at the preset locations.

Mo Yuan's consciousness was like a Clone, locking onto dozens of Green Vine Demons simultaneously. He pointed his Thunder God Arm repeatedly from a distance, accurately injecting cyan-gold Thunder Rune Dao Seeds into each one!

Sizzle! Sizzle! Sizzle! The entire edge area of Mo City seemed to instantly turn into a mad plant purgatory!

Dozens of Green Vine Demons grew and mutated wildly at the same time!

The emerald radiance and the dark gold thunder patterns shone against each other!

Violent vitality and thunder power permeated the area, causing the entire underground space to tremble slightly!

Their new vines were thicker and tougher, like activated giant cables. With thunder patterns flickering on their surfaces, they not only firmly reinforced the rock walls but even began to actively weave and interlace, forming walls of living, thunder-patterned wood at tunnel entrances and important junctions!

On the walls, those huge thunder buds slowly rotated, locking onto their targets.

Mo Yuan's thoughts stirred, and a test command was issued.

A remnant of an Ironclad Corpse, left over from a previous battle, was thrown toward a tunnel entrance.

The moment the Ironclad Corpse entered the attack range of the Thunder Wood Demon at the tunnel entrance!

On the wooden wall woven from vines, three huge thunder buds suddenly bloomed!

The center of the flowers was not soft tissue, but three incessantly rotating thunder-light vortexes composed of highly compressed thunder energy!

Hum! There was no need for fine control from Mo Yuan; based on their hunting instincts, the Thunder Wood Demons automatically locked onto the target!

Three condensed, cyan-gold dual-colored beams of destruction instantly shot out from the thunder-light vortexes, precisely striking the Ironclad Corpse remnant in a crossfire!

Boom! The remnant didn't even have a chance to explode; it was instantly vaporized!

Not even a scrap was left!

Only a hint of a burnt smell and leaping electric arcs remained in the air.

Automatic target acquisition! Instant destruction!

And this was only the beginning!

As more and more Thunder Wood Demons were transformed, their new vines connected and intertwined with each other, eventually forming an endless, constantly writhing and growing forest of demonic plants, shimmering with thunder patterns, across the entire outer rock walls, tunnels, and even some open domes of Mo City!

This forest was alive, angry, and was Mo City's most loyal, tireless guardian!

Countless thunder buds appeared and disappeared within the forest, like countless cold, compound eyes, monitoring all intruders.

Between the vines, thunder light flowed, forming invisible energy barriers.

They could even absorb the thin Spiritual Qi and thunder energy drifting in the air to replenish their own consumption, achieving a low level of self-sufficiency!

[Demonic Plant Fortress]! Formed!

Mo Yuan stood in the Central Plaza, sensing the underground capital that had instantly become "alive."

On his cold face, a faint curve of satisfaction finally appeared, one that was enough to freeze all things.

Defense no longer relied solely on cold Formations and energy-consuming turrets.

Now, the entire Mo City itself was a sleeping... living behemoth covered in thorns and thunder!

The value of the emerald spirit dew far exceeded expectations.

Han Li's "gift" was transforming into tangible power for the Mo Sect at an astonishing speed.

This sequence Dynasty buried deep underground had once again completed a jaw-dropping... armed evolution!
