The drumbeat shook continuously, and Zhuang Yichen landed next to a building that was only half left. Not far ahead, the front has completely turned into a pile of rubble and brick paved flatland, and the iron hooves of countless war horses step rhythmically past, and the whole land is trembling.

As soon as he landed on the ground, Zhuang Yichen immediately used the Tower of the Undead to cover himself and Niuniu's breath, and then silently sneaked into the only remaining broken wall and hid carefully.

The Tower of the Dead was able to shield his breath and block the detection of spiritual power, which was a newly discovered function after he had just broken through the realm. In addition, after the spatial intensity rose by one level, a lot of Zhuang Yichen's magic was also affected.

The first is the summoning of the undead, and the current summoning of the undead can no longer summon the undead from the necromantic space silently, and it should be a killer move. And teleportation can no longer be performed at will without any scruples.

The undead flew to the edge of the battlefield, and a majestic spiritual power instantly swept over the area where Zhuang Yichen had disappeared. Zhuang Yichen could clearly feel that his spiritual power had passed around his body, but he was silently blocked by an invisible oil film, and he couldn't see anything abnormal.

After sweeping back and forth four or five times, that spiritual power reluctantly retreated. But Zhuang Yichen did not slack off at all. As soon as the spiritual power of the undead subsided, Zhuang Yichen immediately carefully sensed the environment around him, and then released two scarred minotaur warriors, found the direction of the basement of this building, violently cleared a passage, and then hid in the basement that was still well preserved.

A large patch of cement tiles was re-covered at the entrance staircase, and everything was restored to its original state. Zhuang Yichen had just finished all this, only to see that the undead had directly transferred a small group of necromantic cavalry, and with an order, the iron hooves of more than twenty horsemen were shining with red fighting energy, and the short knives that they were wielding directly forcibly pushed the entire block back and forth.

The rumbling sound suddenly became loud, and the half of the small building, which was already crumbling, immediately collapsed under the devastation.

Smoke and dust were everywhere, but nothing was found. The soul fire in the undead's eyes flickered a few times unwillingly, and then turned his gaze to the big battlefield ahead.

Although the human ladder offensive of the heavy iron cavalry was swift, it was quickly shattered when the human army firmly controlled the air power. The scorched black earth was littered with countless fragments of white bones, and bits of dark green or dark blue soul fire continued to float from the battlefield, and then slowly dissipated.

After a long stalemate, I saw a sharp cry in the distant sky, and a huge queen with a harpy body galloped towards with hundreds of harpy banshees.

The helicopter battle group, which was constantly spewing tongues of fire, was immediately attacked, and the harpy had a human body and a pair of huge eagle wings behind her. Her arms turned into two sharp claws, her slender thighs were exposed, and her feet were similarly covered with sharp claws.

I saw a harpy deftly dodge in the air a few times, then dodged the two terrifying cannons, and directly stuck to the cockpit of the helicopter.

Her sharp claws easily tore through the alloy hatch on one side of the plane, crushing the pilot's head inside with a claw. The plane spun weakly and crashed to the ground, and with a bang, it turned into a flaming fireball.

The fragile defense capability of helicopters requires an absolutely safe airspace environment in order to play the role of a fire fortress in the air. The Queen of the Eagle Body has joined the battlefield, and in just a few minutes the army has lost more than a dozen aircraft. No one could afford such a terrible loss, and the forward fortress immediately recalled the plane back to the camp.

Hundreds of anti-aircraft machine guns on the city walls rang out at the same time, and the dense bullets weaved into a fiery red net of airfire, which was hidden in the white sky lit by flares, and blocked the harpy from the advancing fortress.

As soon as the air superiority was gone, the military's blocking firepower instantly dropped a notch, and although the Necromantic Iron Cavalry behind him was frustrated in the early charge, the main force was not damaged. I saw that the fiery red soul flames formed a long flowing river, rapidly mobilizing towards the battlefield.

Every bit of soul fire represents an elite necromantic iron horseman, invincible in the human ladder attack, and the entire advancing fortress is in danger!

At this moment, I saw that twelve looming pillars of light suddenly crossed the sky shrouded in darkness in the distance, and twelve Guardian-2D long-range rockets came in an instant, covering the city around the advance fortress again in an instant.

The 12 rockets are high-explosive anti-personnel submunitions, each of which carries hundreds of bullets. The dense artillery fire raged, and in just an instant, the army of hundreds of thousands of undead was enveloped in the artillery fire.

Zhuang Yichen has been completely buried deep in the ground by the thick rubble, so that under the magnificent battle, he also has a rare time to breathe.

The high temperature of the raging artillery fire and the fighting spirit of tens of thousands of necromantic iron horsemen had already disturbed the magic elements in this space in a violent and uneasy way, and at this time, he had no way to cultivate, and he could only secretly release a trace of spiritual perception, carefully observing the battle situation in the outside world.

After the artillery fire was raging, the terrifying heat had not yet dissipated, and a little deep red light between the smoke and fire rain in the sky lit up again. In a conventional war between human beings, such a volley of artillery fire, hundreds of thousands of living targets gathered together will immediately disappear.

However, the Necromantic Riders are no ordinary humans, and their bodies are strong enough to retain most of their living power under such terrifying fire. The long river of red soul fire converged again, and most of the original hundreds of thousands of necromantic iron horsemen were knocked out by successive artillery fires, but they still gathered more than 50,000 intact troops.

The soul fire in the undead commander's eyes was dull, and the air around him twisted and transformed under the heat of the incendiary bomb, and the blood-red armor on its body was a strange blur.

It still raised its long sword, aimed it at the silent steel fortress in front of it, and swung it down again!

As a necromantic creature, it has no feelings, and it doesn't feel tired. There is only one command in its simple divine sense, take this fortress!

"Knock~Knock~~Knock!! Boom~~!! ”

The sound of iron hooves like drums sounded again, faster and faster, more and more wide, until finally they converged into a deafening piece, rushing through the trembling earth and rushing forward the fortress of silence like an iron giant.

The battle sounded again, and at this moment, the soul fire in the eyes of the undead commander suddenly flickered, and then it suddenly reined in the horse's head, and the iron sword in its hand pointed straight into the sky.
