Full-Time Magister: The Ruler of Wind and Rain

The underwater world of Jiashan Lake is not as desolate as people imagine; on the contrary, it is filled with an unsettling noise.

It was the muffled sound of undercurrents crashing against rocks, the rustling of water plants frantically rubbing against each other in the murky water, and even more so, the sound of some kind of breathing hidden in the dark depths, greedily watching. Wang Yu floated in the water about three meters above the lake bottom, his body wrapped in the streamlined "Quiet Mooring Water Guardian," like a piece of amber emitting a faint blue light, standing out conspicuously in this dark green chaos.

The scene before him was truly shocking.

The main pillar of the array, as thick as two people could hug, now seemed to be afflicted by some incurable disease. Dark green ghost water vines, like living veins, densely coiled around the pillar's surface, greedily digging their roots into the pillar's texture, each pulsation drawing upon the water elemental magic flowing within the array. The array runes, which should have radiated a lustrous blue light, were now dim, like candle flames about to go out.

"You seem to be enjoying your meal."

Wang Yu sneered inwardly, flicked his finger, and several pre-refined cloud gold components slid out of his spatial ring and floated in front of him.

Cloud Gold is a material with excellent conductivity for elemental energy and isn't particularly expensive, making it a versatile material for constructing array loops. Wang Yu didn't rush to clear away the Ghost Water Vines; instead, he swam to the huge gap gnawed into the base of the stone pillar. That was the source of the leaking demonic energy and the key to the entire array's precarious state.

Wang Yu intentionally made the prefabricated Yunjin component slightly larger than the gap, so that it could be precisely sculpted underwater to fit the gap. Under the sharp water blades, the not-so-tough Yunjin was quickly sculpted into a shape that perfectly filled the gap.

"go!"

Propelled by the water flow, the Yunjin component steadily locked into the gap, and the upper and lower fixing parts slid into the slots. The moment the gap was filled, the entire stone pillar trembled violently. The previously dim water elemental guiding track seemed to have been injected with a stimulant, instantly becoming much brighter.

The ghost water vines clinging to the stone pillars convulsed violently as if they had been electrocuted, making a sharp sound like fingernails scratching a blackboard.

"Now!"

A flash of blue light appeared in Wang Yu's eyes, and the water system star map, which had been poised to strike, vanished beneath his feet in a flash.

"Calmness, Stormy Waves, Expulsion!"

However, instead of unleashing a wide-ranging, indiscriminate attack, he used a "shaping" technique to compress the originally violent impact of the storm into a ring-shaped, sharp wall of water.

The water wall clung to the surface of the stone pillar, ruthlessly "shaving" it off from bottom to top!

Crackling sounds echoed through the water. The seemingly resilient Ghost Water Vines were as fragile as seaweed in the face of the mid-level magic imbued with the power of the spirit seed. The dark green broken vines burst open in the water, slightly muddying the surrounding waters.

Wang Yu summoned a stream of water to disperse the muddy water in front of him. As the ghost water vines were cleared away, the formation was completely restored.

A vast and pure torrent of water elemental energy surged along the circuit. The water stagnation caused by the energy leak was instantly cleared, and the underwater currents of Jiashan Lake began to flow orderly along their predetermined paths.

However, Wang Yu did not relax at all. Instead, his muscles were tense as he turned to look into the deep darkness.

The water surge caused by the reactivation of the formation was like striking a gong in a quiet library.

For some who have long regarded this place as their private territory and rely on absorbing leaked magical energy for survival, this is tantamount to taking away their livelihood and declaring war on them.

"They're here."

Wang Yu's water-based cultivation gave him a keen sense of water flow.

In his perception, three turbulent currents were tearing through the lake's barrier at an alarming speed, encircling him in a triangular formation.

It was a three-headed, slender fish-like demon covered in black iron scales.

The two on the left are about four meters long, with bloodthirsty red eyes. Although their scales are hard, they are also mixed with some colors, so they are probably at the level of a minor general.

And the middle one...

It is over six meters long, with a dorsal fin like a row of upright steel blades, and its scales are a deep, dark black that reflects a metallic sheen in the dim light. With just a flick of its tail, it creates a visible white bubble behind it.

A battle against a general-level, iron-boned black shark!

These demons are known for their iron-hard bones; once they charge, they can even smash through the bottom of a ship made of steel. They clearly used this stone pillar that leaked magical energy as a natural "feeding trough," and even specially cultivated ghost water vines to "intercept" the magical energy.

Now, Wang Yu has not only repaired the trough, but also uprooted their "crops." This has created a huge grudge.

The three-headed iron-boned black shark suddenly accelerated when it was fifty meters away from Wang Yu. They did not make any roars, but the bubbles thrown out by their violently swinging iron tails made a loud noise.

Three black bolts of lightning, carrying enough kinetic energy to shatter rocks, slammed into the tiny human figure.

The Iron-Bone Black Shark charged with astonishing speed, closing in on Wang Yu almost in the blink of an eye. Two rows of barbed, sharp teeth were clearly visible in its gaping maw.

The impact of this level of force is astonishing, beyond the capabilities of ordinary-grade shield artifacts. The bad news is that Wang Yu doesn't even possess an ordinary-grade shield artifact.

The good news is that he has finished drawing the intermediate-level spell.

"Calmness, Stormy Waves, Expulsion!"

The water element, which was originally easy for the Iron-Bone Black Shark to use, now turned into a kind of prison that imprisoned them. After crashing them to a stop at extremely high speed, it pushed them away into the distance like a dump truck.

This is the characteristic of stillness. It can soothe turbulent waters and also make flowing water freeze instantly.

A smile curved Wang Yu's lips. "Playing with me in the water?"

The turbulent waves gradually dissipated a hundred meters away. The Iron-Boned Black Sharks, now free, were clearly very unwilling and charged again. However, since the distance was now greater, Wang Yu had ample time to prepare. He gathered a wind blade more than a meter long, ready to kill the enemy.

Using wind magic in water is a major taboo, and to be precise, using any elemental magic is not a particularly wise choice, because below the surface, the abundance of water element is absolutely dominant, making it easy for mages of other elements to fail in casting spells if their skills are not very proficient. However, Wang Yu's mastery of both wind and water magic is not shallow, so occasionally breaking a taboo is not a big deal.

Why does Wang Yu insist on using wind-based attacks instead of the readily available water blades?

The answer was revealed the moment the Iron-Boned Black Shark crashed into them.

Just as the leading battle general, the Iron-Bone Black Shark, suddenly charged forward, Wang Yu's other hand, which had been holding back for a long time, instantly unleashed its Water Defense. The perfectly timed flow of water pushed Wang Yu to the side slightly, allowing him to avoid the demon's sharp teeth.

This dodge was not a big deal, but the Iron-Bone Black Shark crashed into the incredibly sharp wind blade. Its proud iron-bone scales failed to protect it, and it was like butter being cut by a hot knife in front of the wind blade.

With a burst of crimson blood shooting out of the water, the great general was instantly disemboweled, its body convulsing in agony, seemingly on the verge of death. But to Wang Yu's surprise, the two slightly slower smaller generals were quite quick-witted. One charged straight at Wang Yu, forcing him to stop himself from finishing off the great general, while the other summoned a stream of water, carrying the heavily wounded great general-level Iron-Bone Black Shark away.
