The undead barrier was broken, and the attacking undead army, having lost the reinforcement of the barrier, immediately fell into chaos.
Rommel’s eyes flashed with cold light as he looked at the human fortress and said, "Orders, open fire, cover the undead army's advance, and command the Tiger people and Bear people to attack."
Rommel knew that this was not the time to hide their strength. If they attacked several times and couldn't even touch the walls of the human fortress, the morale of the entire Ten Thousand Races Alliance would be lost.
On the war fortress, all defensive systems were activated.
From defensive formations to various artillery and repeating crossbows, even the ballistae specifically designed to kill giant beasts were loaded and aimed at the various giant beasts tamed by the orcs.
Zhang Haoran and his three junior brothers, leading eighty thousand disciples of the Heavenly Master Mansion Dao Soldiers, stood on the city wall.
With talismans in their left hands and swords in their right, bolts of lightning of varying power struck the undead soldiers below the city.
Each bolt of lightning took away numerous undead soldiers.
Lin Zhan looked at the undead soldiers below the city with a solemn expression and said, "As expected of one of the top ten races among the Ten Thousand Races, the undead are indeed troublesome."
Ouyang Chengshan nodded beside him and said, "The troublesome aspect of the undead lies in their complete set of troop types. Whether it's magic users, infantry, cavalry, elite troops, tanks, heavy armor units, or cannon fodder, the undead can cultivate all troop types themselves."
"Although the Heavenly Master Mansion's Thunder Punishment is effective against the undead, they are at a disadvantage in terms of numbers. In fact, the true nemesis of the undead is the Angel Divine Race behind the Roman Holy See; their holy light has a natural suppression effect on the undead."
Lin Zhan was startled, then gave a bitter smile, "Grandfather, please don't dwell on this matter. The leading figures of the Angel Divine Race were beaten to death or severely injured by our ancestor. Ancestor Hou Yi even plucked their feathers."
"And their so-called Saint Son was also chopped by me. Even the Saint Son's angelic wings were roasted by Little Gold and Little Black as snacks."
Ouyang Chengshan was stunned and looked at his grandson with a bewildered expression.
"Damn it, I only knew this kid didn't like doing proper things, but when did he become a beast?"
While Ouyang Chengshan was in a daze, energy shells were fired at the war fortress.
Nearly ten thousand energy shells struck the war fortress's defensive formation, creating ripples like water before dissipating.
Lin Zhan felt the power of the Ten Thousand Races Alliance's energy cannons and couldn't help but curl his lips, "What is this thing? Its power is at least thirty percent less than our heavy cannons, and its range is only two-thirds of ours. These are all obsolete products."
Then, he turned to Zhang Dabiao and said,
"Orders, ten heavy cannon platforms, according to the coordinates provided by Xiao Hanyi, fire one base of shells first."
"Orders, Rocket Corps, No. 4 high-explosive rockets, target enemy forces 12 kilometers away, spaced 500 meters apart, in groups of 20, fire five groups."
"Damn, I want to let that stupid fox Rommel see clearly, when it comes to advanced weapons, our Huaxia is the ancestor of his Ten Thousand Races."
As soon as Lin Zhan finished speaking, Ouyang Chengshan patted his shoulder and said, "Zhan'er, look, the Deathless Knights and Abomination Legion of the Undead have been deployed."
Lin Zhan followed Ouyang Chengshan's gaze and saw knights in black heavy armor wielding greatswords, moving rapidly through the enemy ranks and approaching the city walls.
The Abominations, like small mountains, dragged their heavy bodies and crawled towards the city walls.
Lin Zhan curled his lips, "Damn, how can this thing be so disgusting?"
"Orders, deploy reinforced rapid-fire cannons, use alloy shells, target the Deathless Knights."
"Orders, prepare the launchers, aim at the enemy Abomination Legion, and launch concentrated incendiary oil bombs."
The sound of the city wall's mechanisms once again rang out. Four thousand twin rapid-fire cannons, shining with cold golden light, rose from the gun platforms behind the city wall. The operators directly aimed at the rapidly moving Deathless Knight Legion and began to roar.
Concentrated incendiary oil bombs were fired from the fortress, flying towards the Abomination Legion.
The sound of explosions echoed continuously. The concentrated incendiary oil bombs detonated, setting the entire Abomination Legion ablaze.
The mountain-like Abomination Legion even emitted wisps of green smoke, drifting towards the war fortress.
"Undead Plague, a good trick," Lin Zhan said dismissively as he watched the slowly drifting green smoke.
He then took out another jade talisman, and a new formation generated a transparent energy shield that covered the war fortress.
It was the Air Purification Formation that Lin Zhan had asked the young Taoist priests to prepare in advance.
"Everything Rommel can think of, I have thought of. Everything Rommel cannot think of, I have also thought of. Undead barrier, Undead Plague, the next should be Undead Resurrection."
As if on cue, before Lin Zhan could finish speaking, a dark chanting sound arose from the attacking undead troops below the city.
Soon, the creatures and corpses covered by the Undead Plague began to slowly transform into undead creatures. The corpses that had already fallen rose again and launched an assault on the city walls.
"Alas, the Ten Thousand Races Alliance has been fighting against humanity for tens of thousands of years, and they still use these old tricks. They don't know how to innovate at all."
Lin Zhan shook his head and muttered with an expression of the Ten Thousand Races Alliance being ignorant.
"Orders, detonate all bombs within a ten-kilometer radius, leave none behind."
As soon as Lin Zhan gave the order, a moment later, violent explosions occurred within a radius of 2 to 10 kilometers outside the city walls.
The entire area outside the city began to shake as if an earthquake had occurred. Huge cracks, several meters wide and hundreds of meters deep, appeared on the ground at the feet of the Ten Thousand Races Alliance.
Countless soldiers of the Ten Thousand Races Alliance were either blown to pieces by the bombs or fell into the cracks.
For a time, the area outside the city was like an apocalyptic earthquake, incredibly tragic.
"Holy crap, who buried these bombs? Truly..."
After the explosion, Rommel directly announced a retreat, and the remaining soldiers of the Ten Thousand Races Alliance retreated like a tide.
However, the soldiers of the Ten Thousand Races Alliance within two kilometers of the city walls could not retreat.
Li Siyi chuckled, beckoning the Modao Army to jump off the city walls and begin reaping heads.
