At the same time, dozens of C4 bombs exploded across each corridor, their shockwaves powerful enough to overwhelm even the thick concrete walls. Large sections of concrete collapsed, completely sealing off the passages. People nearby were struck by flying chunks of concrete. Most of them, like the man with the silver mask, were panicking. The employees who had managed to work here were among the senior staff of Blood Shadow, and they had previously trusted the organization's defenses following the earlier perimeter explosions. Yet no one had anticipated that just a few minutes later, an explosion would occur within the building itself—marking the first time in Blood Shadow's history that an internal attack had taken place. Because such an event had never happened before, everyone's vigilance had significantly diminished, and emergency protocols had long since become mere formalities, ineffective in practice. The scene was a chaotic blend of cries, screams, and disorganized crowds rushing back and forth. The silver-masked man burst out of his office, grabbing an employee who was trying to flee, and demanded, "What's going on? Where did the explosion happen—was it the weapons storage or the training field? How could they have been so careless!" The first thought that flashed through his mind when the explosion occurred was that the weapons storage had been compromised. Although the training field frequently used large weapons, it was rarely capable of producing such a powerful blast. "Lord Blood God, neither the weapons storage nor the training field—it's the safety corridor," the man, held by the collar, stammered, "Five out of the six safety corridors were completely destroyed. Please, Lord, you must evacuate now—this is definitely a terrorist attack!" Honestly, with the term 'terrorist attack' being used now, you'd think we were the pioneers of such incidents—how daring of you to even suggest that. "Everyone, evacuate immediately." As soon as he finished speaking, he sensed a hint of conspiracy. If the other side could destroy five channels, why leave one intact? There must be a trap set up there. With this realization, he did not stop the crowd from rushing toward that end, but instead climbed to a higher vantage point and observed from afar. Hundreds of people poured into the relatively narrow passage, pushing and jostling one another, unwilling to fall behind, which brought their pace to a near standstill. Suddenly, at the far end of the passage, a shadow flickered—three large-caliber tracked guns, previously covered by canvas, now revealed their formidable presence. Beneath the massive ammunition boxes, wires connected, enabling remote electric firing. The people at the forefront were stunned, but those behind remained unaware, continuing to press forward without pause, thus preventing them from stopping. Ddah-dah-dah… Ddah-dah-dah-dah-dah… All three machine guns erupted into fire, spitting out 12.7-millimeter high-velocity rounds like hail. These rounds were powerful enough to take down standard light armored vehicles, and when aimed at personnel, they were absolute game-changers—capable of easily piercing two human bodies and delivering a lethal blow to a third. If limbs were struck, bones would shatter along with the tissue; if the torso was hit, large chunks of flesh and bone would be torn away, or a gaping wound the size of a bowl would be left behind. With the gunfire, limbs and body parts scattered everywhere, the scene became exceptionally bloody. The people in front began to fall one after another. Those behind realized the severity of the situation and tried to flee—but by then, escape was no longer possible. Except for a few at the very rear, the rest were reduced to pulp within fifteen seconds. Blood flowed like rivers across the ground, and the walls were streaked with splashes of blood and torn flesh. The man with the silver mask gasped heavily, his fists clenched. He had anticipated an ambush at that location, but hadn't expected such a devastating outcome. According to his original plan, the enemy must have planted bombs there as well—designed to maximize casualties, so that the bombs wouldn't detonate until a sufficient number of people reached the site. Once triggered, the enemy's strategy would be fully executed, and a modest sacrifice would be well justified. Several workers in green uniforms carried rocket launchers and pressed the firing buttons at the far end of the corridor. The rockets roared into the air. Their objective was to disable three machine guns, clearing a safe path for evacuation. Though the machine guns continued to fire, one bullet struck a rocket mid-flight, causing it to explode in midair. The workers didn't lose much hope and launched a second salvo of three rockets. Boom! Boom! At least two rockets exploded near the heavy machine guns, instantly silencing their fire. The crew set down their launchers and advanced forward, stepping over the bodies of their comrades. Relieved that no further dangers had occurred, they finally exhaled, unconsciously quickening their pace. Just as they reached the vicinity of the exit, an infrared-triggered mine exploded, killing several people at once. Qin Feng, sheltering beneath a ventilation shaft, watched with cheerful satisfaction as he had transformed the scene into a battlefield of relentless destruction, efficiently handling over half of the on-site staff—what a simple feat. The Blood Shadow Killers weren't much better. The silver-masked man's heart sank; with so many casualties, even if the intruders were secured, the team would struggle to regain its previous operational rhythm in the near term—now truly battered. He gritted his teeth and issued the order: "All remaining killers and trainees, form assault teams and conduct a thorough, systematic search—make sure every intruder is captured!" They had no idea how the intruders had entered, or how many there were. Within a short while, several four-person search teams were assembled and equipped, moving out to conduct thorough inspections across different areas. Personnel from the teams had to coordinate closely, undergo rigorous checks, and only after verification of their identities could they proceed to the secure zones. Qin Feng didn't mind these search teams; what he was truly concerned about was whether, beyond the six clearly visible evacuation routes, there were hidden passages concealed within. Given that the opposing forces now felt capable of mounting a counteroffensive, they had not yet chosen to retreat. They also understood that if they failed to maintain control of the situation, the exposure of these hidden passages would eliminate their sole chance of escape. When one of the search teams reached his position, Qin Feng calmly tossed a high-explosive hand grenade to them. The grenade contained hundreds of small steel balls inside, delivering a devastating impact. *Plink...* The grenade landed with a crisp, clear sound. Several people reacted promptly, aligning their guns toward the ground. When they saw what it was, they all went dumbfounded, instinctively turning to flee. Boom— the hand grenade exploded, steel fragments scattering in all directions, and four of them fell dead at once. Someone immediately reported, "Lord Blood God, the entire Sixth Assault Group has been eliminated. The enemy has exposed their position. The Third and Ninth Groups are en route now, and the other three groups are also moving toward us!" The man in the silver mask, seated in the command room, spoke calmly, "We must eliminate him. We need to identify who he is."
