This was not because Yang Mu was particularly strong, but simply because this crushing pressure targeted not the body, but the mind.
Seated at the center of the array, Yang Mu downed the Spirit Ascension Potion in one gulp. Purple flames ignited across his body, and just as they were about to burn away his lifespan, the potion's properties allowed his mental power to undergo an instant transformation.
It was like a fill-in-the-blank question. Others still had to work through the calculations, while Yang Mu already knew the answer and simply wrote it down.
After the nature of his mental power transformed, Yang Mu began using the Mental Pressure Array to compress it, condensing it again and again.
In the end, his intangible mental power took on a mist-like form within his mind. Within that misty mental power, a spell model rapidly took shape.
It was like fitting countless building blocks into predetermined slots. It was only a First Order spell model; engraving it posed no difficulty for him.
At last, a spell model resembling a six-sided crystal floated within the mist-like mental power. Around it hovered three smaller, flat spell models.
They were the Apprentice Rank spell models Yang Mu had engraved before.
However, after they drew close, aside from the second Elemental Affinity, the other two spell models began changing under the support of Yang Mu's mist-like mental power.
Their structures became more complex, shifting from flat forms toward three-dimensional ones. When the transformation was complete,
the originally dense mist-like mental power in Yang Mu's mind had become extremely thin. Three different polyhedral spell models surrounded a small flat spell model.
This was the origin of Unranked Spells. They would automatically consume mental power and advance according to the Mage's current rank, meeting the Mage's present needs. Every Unranked Spell was exceedingly precious.
The completion of the spell model meant that Yang Mu had become a Formal Necromancer. Not only had the quantity of his mental power increased, but more importantly, its quality had improved.
If his previous mental power had been ten cubic meters of limestone, then his current mental power was twelve cubic meters of granite.
Yes, the total amount of his mental power had only increased by two points.
But if calculated according to spell consumption, his mental power had increased twelvefold. Every point of mental power he had now could cast spells equivalent to what ten points had done before.
Moreover, his mental power was now sufficient to support the casting of First Order spells. Previously, even he could only use tricks like Mixed Magic to reach the First Order level.
Its essence had still been Apprentice Rank magic. The gap in mental power quality could not be crossed.
But now, Yang Mu raised a hand and lightly tapped the Void.
"Dark Barrier!"
With Yang Mu's low chant, a three-dimensional spell model half a person tall flashed before him and vanished.
The fleeing Undead was wrapped in a layer of black energy, easily blocking the cannonballs coming from behind.
Chasing at its heels was its old friend, the Gale.
Besides that, beneath the sea, a massive figure was entangled with the Undead's tentacles. A blood-red crescent moon gleamed in the eyes of this enormous sea monster.
Its sharp dorsal fin tried to ram the Undead again, but this collision was no longer as effective as before. Instead, it was like striking a cliff at the bottom of the seabed.
Hard and unshakable.
"Damn it, raise sail number two! Black Luo, are you stupid? Sail number two, sail number two!"
"The rest of you, fire like hell! I spent a fortune this time and bought twenty cannons. Blast them to pieces!"
Jack gripped the wheel while continuously roaring curses.
Six days had passed since Yang Mu entered the deck. Everything had gone smoothly during the first few days, with calm winds and quiet seas.
But two days ago, the Undead, drifting at sea, had been pursued by the Gale. This time, the Gale had clearly come prepared.
Even when the Undead released black mist, it could not interfere with the enemy. They could still accurately locate them and fire cannonballs.
On the Gale, Roderick stood beside someone wearing a starlight cloak. Before them floated a crystal ball the size of a human head, displaying the positions of the Undead and the Gale.
Any experienced captain could lock onto the Undead ahead without even needing to look at anything else.
The reason the Gale had been able to find the Undead across the vast ocean was this Astrologer.
"Major General Roderick, although I don't know what happened, I suggest you stop pursuing them. I have a very bad feeling."
"Entropy Annihilation Finger!"
The Astrologer who had been speaking was pierced through the forehead by a suddenly appearing black beam. After the black light vanished, his body began to disintegrate.
He turned into countless blood-red particles and scattered through the air. Roderick was about to reach out and touch the blood-red powder when a scream came from the side.
He turned and saw a sailor clutching his face, screaming and rolling across the deck. Red blotches rapidly spread over the parts of his body that had touched the powder, and then those areas began disintegrating as well.
It was not just human bodies. Even the ship struck by the black beam began to disintegrate, though the powder from the ship was not blood-red, but the color of wood.
With a wave of Roderick's hand, Wind Blades appeared and cut away the disintegrating sections of the ship. A whirlwind swept up all the powder along with the severed hull and hurled it into the sea.
Only then did he stare gravely at the black mist ahead, as if he could see through it and glimpse Yang Mu standing by the Undead's rail, slowly withdrawing his finger.
Entropy Annihilation Finger was the spell model Yang Mu had engraved. He had created this spell himself as a byproduct of his research into the Law of Entropy Increase. Its power was enough to rival some ordinary Second Order magic, yet its spell model could be engraved at the First Order.
Its only problem was that it was excessively complicated. Without research into the Law of Entropy Increase, it was easy to fail and difficult to learn.
But that was only true for others. For Yang Mu, its creator, it was as easy as clapping one hand against the other.
Yang Mu was very satisfied with his spell's power. The Gale behind them no longer continued its pursuit.
Eudora and Barrel appeared beside Yang Mu.
"Go. Kill that thing beneath the sea with the Undead."
After Yang Mu gave the order, the two figures leaped into the sea.
After the two First-Order Undead entered the water, huge disturbances erupted beneath the Undead. Deep roars rang out, and from time to time, black sword light shot from the water into the sky.
Only half an hour later did the commotion cease. The Undead let out a delighted low hum, its hull swaying slightly. Clearly, the Undead was feeding as it sailed.
As for what it was eating, there was no need to say.
