Just as the alliance was thinking about what to do next after being surrounded by monsters on all sides, a calm voice sounded from their communicators, making them regain their composure. "Shift to Plan Z." As soon as the order was given, the Soldiers retreated in haste, running as fast as they could. Their Supreme Commander had created different strategies for different situations, and Plan Z was one of them. When this plan was in effect, all the infantry on the ground would retreat in haste, while the Monarchs, Thrones, and Team Alpha would cover them from the land and sky. The Naval Fleet in the sea would then unleash all their long-ranged missiles, aiming at the locations their Supreme Commander would designate. Thirteen, who was inside his Humvee located at the rear of the formation, ordered Colbert to retreat to the second line of defense, which he had prepared two days ago. The soldiers who were running away as fast as they could would occasionally turn their heads to the back to see what was happening behind them. They saw the three Monarchs and the Thrones, alongside the Aerial Units of the Army, hold their ground, buying time for the army to retreat. Those who looked back longer inevitably noticed that the support fire coming from the sea only targeted the Giant Centipedes, the Goblin Riders, and the Orc Riders. The Undead Army was untouched, and this was also the monster that they were currently fighting. Jalrog and Erasmus eyed each other for a few seconds before they, too, joined their soldiers in battle. "Monarchs, please deal with the Centipede King." "Thrones, deal with the Death Lord." "Team Alpha, support the ground forces as they retreat." """Yes, Sir!""" Thirteen remained calm as he gave orders left and right. "Looks like I'm being underestimated," the Death Lord, Erasmus, said as he faced the Thrones in the sky. Arthur, who was at the very front of the battle, clashed with the Commander of the Jinns. At the present, he was equipped with peak Gold-Grade Armaments. He had no intention of letting the Alliance know that he owned Mythical Artifacts, knowing that it would cause a lot of trouble. Aside from Lawrence and Tristan, no one else knew that the Patriarch of the Leventis Family was in possession of Armaments, which only the Monarchs in Pangea were supposed to have. Unlike most of the Monarchs, the Thrones were all battle-hardened warriors, for they were the ones who usually fought on the front lines of every monster invasion. The Thrones of the Dvalinn Federation had fought together countless times, so their teamwork was impeccable. The Thrones from the Aldebaran Continent were the same, seamlessly dealing with Erasmus and his Elite Guards, who were protecting their liege. Meanwhile, on the ground, Lawrence, Wendell, and Trevor realized that the Centipede King was more powerful than they initially expected. Originally, they thought that fighting against the Centipede King with three Monarchs was already overkill. However, after a minute of fighting, they understood that their opponent was incredibly strong. Jalrog, who was also surprised at how strong it was, laughed internally as it used the Monarchs as training dummies to check the extent of its abilities. Lawrence was being pushed back, and Wendell, who acted as his support, didn't fare any better. If not for the fact that Trevor was there to support the two, one of them might have already been seriously injured after a few exchanges with the Monster, who was now a Pseudo-Rank 9 Sovereign. As the powerhouses of both sides clashed with each other, the Undead Warriors were closing the gap with the retreating infantry. The cover fire from the sea was only targeting the Giant Centipedes, the Goblin Riders, and the Orc Riders, so the Undead was left untouched, allowing them to move unhindered across the battlefield. But, just when they were only a hundred meters away from the closest soldier running away from them… One of the Skeleton Soldiers stepped onto a mine, resulting in an explosion that blasted everything within a ten-square-meter radius of the mine. Soon, more explosions spread on the battlefield as the enemy stepped into the killing zone that Thirteen had prepared in advance. While the stockpile of ammunition and missiles of the Alliance was at its lowest, the stockpile of land mines was left untouched. The locations of the mines were marked on the ground with a red spray. Before the battle started, the soldiers were already briefed on which path to take when an order to retreat was given. In fact, when they marched on the battlefield, they were asked to travel on this same route, so that they could familiarize themselves with the path where they could make their escape. Seth, Allen, and their armies couldn't help but admit that this strategy was indeed a good method of simultaneous retreat and attack. While they were retreating to their second line of defense, the enemy's numbers were gradually being reduced by the minefield. "Strikers, blow them to oblivion!" Thirteen ordered. The tanks and artillery units, who were waiting for their turn to unleash hell, all bombarded the undead army with shells that blasted them to pieces. While this was happening, Lawrence contacted Thirteen directly and told him that they could no longer hold back the Centipede King. "Monarchs, Thrones, and Alpha Team, retreat," Thirteen commanded. "We will enter the Second Phase of the battle." After receiving their orders, the Monarchs and the Thrones immediately disengaged with the Centipede King,l and the Death Lord, retreating to their second line of defense. "Commander, we've run out of missiles," the Admiral of the Naval Army, Hugo Riggs, reported. "We can no longer provide support fire." "Thank you, Admiral," Thirteen replied. "You've done enough." Since the cannons of the Warships were unable to reach the location where the battle was happening, they used all the missiles in their stockpile. Even the missiles that belonged to the Ashford and Stallard Naval Fleet had been used up, making the Warships unable to help their comrades who were risking their lives on land. 𝚏𝗿𝗲𝐞𝐰𝚎𝕓𝐧𝚘𝘃𝗲𝐥.𝐜𝚘𝕞 With the support fire from the sea no longer a threat, the Jinn Army surged like a tide toward the Human Army. Jalrog glanced at Erasmus, who was busy reviving the fallen monsters to add to their army, for half a minute before following his Centipede Army to the front lines. Since the Death Lord was mounted on the Undead Wyvern, Vannaroth, the Centipede King deemed that the time wasn't right to show its true colors. For the time being, it would just play along with the Death Lord's plans to wipe out the Wanderers until the perfect opportunity presented itself.
