The heart of the human defense effort against the monsters was undoubtedly the st zone.
A one-kilometer expanse meticulously engineered to unleash havoc and shatter anything or anyone brave enough to venture within its bounds.
The first time that Rocky witnessed it in action, he realized just how formidable the zone was as within seconds it decimated thousands of undead skeletons.
Arrows, mortar, spells, bombs, heavy artillery.
Every form of long range AOE attack was all concentrated in one stretch ofnd, obliterating any army brave enough to walk into it.
From the first wave of opponents, not a single undead skeleton was able to cross even half-way through the st zone, as within seconds, the undead were reduced to a pile of bones and ashes.
"Alright, hold your fire-" Pdin Patrikmanded, as the archers and mages in his unit paused their fire when it seemed like the enemy waspletely decimated.
"Guildmaster Karna was right to wait longer, the first wave of undead were indeed too weak. Saving the ditch trap for stronger opponents was a wise choice" Rocky murmured to himself as he observed the battle develop.
The decimation of the front lines of the undead, created a noticeable gap between the front lines and the next line of emerging troops, as the stronger undead giants and skeletal champions made their way to the front.
Up till now, the outpour of monsters from the tower was relentless, every second a few thousand new monsters emerged outwards with their strength and quality slowly but steadily improving, hence, although humans were demolishing their front line forces, the overall number of enemy troops were only going up every second.
**************
"Hey Karna, I think it''s time…." Neatwit eventually said as he noticed that the entire ditch radius waspletely filled with undead horsemen level troops or higher.
"Just a little more…." Karna said in response, as he let the enemy troops approach with ice in his veins, drawing even more to his death trap.
"Hey, we also need to slow down their progress. They''re marching too fast. We need the ditch" Neatwit reminded, as Karna pointed his palm towards Neatwit, urging him to stay calm.
For a full two nerve-wrecking minutes, Karna only observed the enemy''s march, as more troops crossed the minefield and reached the st zone.
For a second time, the arrows, mortar and spells rained down on the enemy troops, forcing them to face significant troubles, however, even then, Karna did not set off the ditch trap.
At this point, even Cody who was back at themand center began feeling nervous, however, despite the pressure mounting from all sides, Karna kept his calm.
*ROARRRRRR*
A Gluttoral roar epassed the entire battlefield as another wave of chilly air swept outwards from the tower.
Out came a legion of skeletal rhinoceros warrior''s, as they rushed straight out of the tower gate at full speed.
*Thud* *thud* *thud*
Even a few kilometers away, Karna could feel the ground beneath his feet rumbling as the rhinoceros legion marched out and it was only when the rhinecores legion was half-way across the ditch trap, that Karna finally decided to activate it.
*KABOOM*
Arge explosion that caused a mini earthquake took the battlefield by storm.
All the thousands of explosives ced underneath the make-shift surface blew up at once, blowing apart the fake surface and causing hundreds of thousands of troops to fall to a 100 feet drop of death.
To make matters worse, the walls of the ditch were inscribed with the highest level of fire spells and hence once the troops fell a hundred feet, they were then subjected to an inferno like heat, that reduced the survival chance of any undead to zero.
*CHEERS*
Maddening cheers went up throughout the front lines as hundreds of thousands of strong undead were plunged to their deaths, as even Neatwit lost his mind at the scene.
To make matters worse for the undead army, the undead rhinecores who were running out of the portal at top speed were unable to stop themselves in time to not fall into the ditch even after it blew up, as one after another they kept jumping into their fiery deaths.
"What a master-stroke! Absolute genius-" Neatwitplemented Karna, pping him tightly on the back, as at that moment even Karna let out a rare smile, feeling goosebumps go up and down his spine.
"Rocky''s strategy was brilliant. That kid has a promising future as a tactician" Karna said in excitement, as although he wasn''t speaking these words to anyone in particr, the recording cameras that were focused on him still picked it up.
As the undead rhinecores kept jumping to their deaths one after another, the cheers amongst Earth''s troops began growing louder and louder as for a second time, they managed to cut the undead tide in half.
With the front-lines decimated under the st zone and the backlines falling into the ditch trap, it was a battlefield wide route for the enemy, as so far, without losing a single soldier, humans became sessful in pushing back the undead wave.
Although they had used up all of their traps and their minefield zone had now been rendered useless, humans had been sessful in extracting the maximum value out of those traps for sure, giving them a great start to this monster wave.

( Meanwhile Rocky )
Rocky cheered alongside the masses when the ditch trap went up, as the site of hundreds of thousands of undead falling to their deaths was one that Rocky was probably never going to forget in his entire life.
Adrenaline coursed through his veins, making him feel hyped for no reason, as he became unable to understand as to why war and carnage felt so appealing to him.
Having tasted the sweet feeling of strategically destroying enemy forces once, Rocky craved for feeling it again, as he felt the urge to jump into the heat of the battle right this moment and take control of a unit as a captain.
Unfortunately however, he was forced to show restraint, as Patrik Pdin was not letting him go anywhere near the front lines for now.
