My World Traveling System: The Harbinger of Death

-----

Frank led his army of Undead forward as Hades channeled all the new powers, he had acquired through accumulating energy over the time he had spent in Terra maintaining the transmigration cycle, and infused it all into the Undead, a sudden enhancement to all their capabilities happened, as all their stats suddenly skyrocketed by over a thousand percent in a single second! Frank was left speechless by then, watching over the enormous changes his Undead underwent as they gained eerie purple and pale blue auras that emanated from the depths of their souls!

"March! Destroy these damn plants!" Roared Hades.

"GRAAAAAHH!!!"

"GRUUUOOOHHH!"

"OOOOOOOOOOOOHHH…!"

The Undead roared with their eerie voices and roars, as they unleashed their phantasmal powers against their enemies, the endless army of plants, life and death clashed against one another as Frank also joined the fight, taking out his Holy Spear and by channeling the power of the pendant of Zeus, he unleashed enormous lightning strikes that roasted alive hundreds of plants everywhere, causing chaos and catastrophes around his surroundings, all while he ran around slashing the plants with his holy spear and also controlling his cosmic energies, which materialized his Divinities into enormous stars of various colors that began to fall over the plants like meteors, exploding into colorful bombs that spread everywhere, consuming everything through cosmic divine powers!

BOOM! BOOM! BOOM!

Frank ran through the battlefield with his weapons as he began to jump around with a lot of agility and dexterity, he continued to fight and unleash all sorts of skills, magic spells, and more that he had learned across his journey, channeling the divinity of fire and Yggdrasil as he generated enormous trees made of holy sun flames that began to spread over the battlefield, growing bigger as they consumed the lives and souls of the plants and then exploding into even deadlier and embracing flames that engulfed everything within 50 meters around them, turning everything into ashes, the Undead were also sometimes caught into it, but they were swiftly resummoned by Hades at the side of Frank, who was floating on his "low energy cost form" which resembled a floating phantom made of pale blue will-o-wisp in the faint shape of a skull.

While Frank showcased all sorts of fantastical powers, the Undead didn't remain in the back, as many of them grabbed the plants and began to poison them with the essence of death they emanated from their bodies, while others devoured them alive and some others slashed them into tiny pieces and then burned them with phantasmal flames. Some others began to explode like undead bombs by the grace of Hades, as he was using the power of "Undead Detonation" to detonate all the undead. The explosions of death took down dozens of plants at the same time.

Although there were millions of plants, their numbers didn't continued to multiply and they lacked the power to summon more of themselves, the plants were being slowly thinned out, and the population of people inside the divine realm was being protected by Frank's Spacetime Clones, which were a new type of clone specialized in controlling space and time magic, alongside the help of all of his wives and friends which he had desperately called inside some minutes ago while Hades and he fought. His clones and his allies created powerful spatial bubbles that saved the people inside from the dangerous outside world, and they were reinforced by elemental barriers as well, making them extra resilient.

Nezhit swung his enormous blade as his three-headed bone horse galloped over the skies, flying over the skies by covering itself into phantasmal flames, his enormous blades slashed through the enemy ranks and opened the way for the rest of the Undead to enter the fray, as the plants couldn't fight against his powerful Sword Techniques combined with his unyielding undeath strength, his slashes had the power to slash entire mountains now, and even giant plant monsters apparently looking like final bosses were slashed into tiny pieces as he swung his enormous blades several times in just a few seconds.

Meanwhile, Zero pointed her new phantasmal bow at her foes, firing barrages of phantasmal arrows that exploded in quick succession one after the other, bringing phantasmal flames that continued devouring life while making the plants decay and grow dry, all while her bone wyvern unleashed his deadly breath attacks, which were made of black flames, consuming the souls of the plants, and killing them on the spot. And if that wasn't enough, Zero sometimes grabbed her daggers and fired them at her foes, the plants, as the daggers unleashed countless slashing attacks by being controlled in midair, unleashing dark and phantasmal attacks, and even spiraling around until they became enormous tornadoes of darkness and phantom.

The battle continued incessantly for several minutes until, the plants continued to fall down in numbers over time, form millions to hundreds of thousands, and then to tens of thousands! However, in the last moments, a mysterious plant monster began to emerge! f𝙧ee𝘄𝐞𝚋𝐧૦ѵeƖ.c𝘰𝓶

TRUUUMMM…!

The enormous wooden roots began to surge from the ground, devastating hundreds of Undead at the same time, Nezhit and Zero began to fight and slice these deadly wooden roots, as the plant monster slowly began to emerge from the ground, Frank and Hades looked at this creature as they realized it was an enormous tree…!

"This tree is… Yggdrasil?!" Asked Frank in shock.

"What is going on?! Isn't this tree your friend, Frank?!" Asked Hades.

"Yeah… It can't be! Yggdrasil is connected to my soul… But… Ah!" Frank muttered, suddenly hearing the faint whispers of Yggdrasil resonating within his mind.

"Frank… This power… Ungh… It is making me go crazy…! Please, help me!"

"What's going on?!"

"Something… It is making me go berserk… The plants are obeying my insanity… There is something… Something awakened in the core of my trunk, take it away! Aaaagggh…!"

"Yggdrasill!!!"

TRUUUUMM…!

Yggdrasil began to go berserk, as the gigantic tree started to devastate everything with its enormous and titanic roots! What would Frank do now?!
