Doomsday: with unlimited warehouse system

Seeing Duke and Little Black join the battle, David's confidence grew. Now they could quickly attack the Titan zombie from multiple angles and directions.

Taking advantage of the evolution gap of the Titan zombie, David began to make arrangements. "Arnold, continue attacking from the right. Cola and Little Black, attack from the left. Sally, step back and protect Sophie. If anyone gets injured, Sophie should immediately start Stellar Healing. Duke, listen to my commands and act accordingly."

Upon hearing David's instructions, everyone nodded. Cola and Little Black let out a low sound. Seeing Little Black return to his side, Cola extended his cat claws and tapped his head, as if reminding Little Black to be cautious. At this moment, Little Black was fully activated in Hellhound mode, and his eyes emitted a terrifying green glow as he stared at the Titan zombie.

Initially, Little Black had been reckless and got injured because he hadn't fully grasped the Titan zombie's strength. Now he became cautious, keeping a watchful eye on his opponent.

The Titan zombie emitted another piercing sound, and a hint of disdain and contempt appeared on the faces of the people before it. At this moment, it had undergone secondary evolution, and the hardness of its skin had significantly increased compared to before, resulting in defense several times stronger than before.

This was the terrifying aspect of the Titan zombie—it could convert the energy stored in its body into defensive strength on its outer skin. Through this method, it could elevate its defense to a horrifying level. The blood that had flowed out earlier was the energy it had stored when devouring lower-level zombies. So now, the Titan zombie's strength was even more terrifying than that of a fourth-level superpower.

Feeling the weight and majesty of the Titan zombie, David tightly gripped his alloy short knife. He understood that the Titan zombie was becoming increasingly difficult to deal with. Their only solution was to surround it, even if they couldn't cause substantial damage to its body. At least they could create an opportunity, and that opportunity was David's goal.

As they watched the Titan zombie slowly move towards them, David gave the command, and the trio—David, Arnold, Cola—charged at it. They had to take the initiative and attack before the Titan zombie launched its assault, in order to seize control of the situation.

David employed the same technique, swinging his alloy short knife fiercely at the Titan zombie's chest. However, this time, there was no sound, and the moment the alloy short knife touched its skin, it seemed to be magnetically attracted, making it impossible for David to pull the knife back no matter how hard he tried. The same was true for Arnold's werewolf attacks and the attacks from Cola and Little Black.

"Terror! This defense is too terrifying!" David's heart trembled. In the corner of his eye, he saw the Titan zombie's fist, as big as a sandbag, appear above his head.

The Titan zombie gazed at David with a playful expression in its eyes and then ruthlessly smashed its fist toward his head. This startled everyone, and they desperately tried to intervene and help David, but the Titan zombie's movements were too fast, giving them no time to react.

"David, be careful!" Sally anxiously shouted to him.

At this moment, David cursed inwardly and without hesitation activated the Space Blade, swinging it with all his strength towards the descending fist! A deep and muffled sound exploded in David's ears like a bell ringing! Immediately, the space around him distorted intensely, forming an air vortex. Due to the tremendous impact, David was flung against the wall, his ears ringing. After a moment of daze, David finally reacted and looked at the Titan Zombie.

Although David's strike bought him some time to escape, it didn't inflict any damage on the Titan Zombie. On the contrary, the recoil was so powerful that it left him internally rattled. However, it made him realize that the Space Blade wasn't magnetically attracted when it touched the Titan Zombie's skin.

David felt it might be due to the nature of the space element. With this realization, he now had a handy weapon to contend with the Titan Zombie. He quickly stood up, glaring fiercely at the Titan Zombie and shouted, "You beast! Today, I'll butcher you!"

David admitted that since his rebirth, he hadn't experienced such humiliation. In an instant, his anger soared, and he unleashed all his firepower! Without any hesitation, he charged at the Titan Zombie, crashing into it recklessly! The Titan Zombie seemed to recognize the power of the Space Blade and constantly waved its hands to defend itself, which created opportunities for Arnold and the others. Soon, they engaged the Titan Zombie in a guerrilla warfare using their speed advantage.

Suddenly, Little Black fiercely bit the ankle of the Titan Zombie, catching it off guard and causing it to stumble. Seeing this, David quickly shouted at Duke, "Duke, now!"

Duke, who was already prepared, immediately launched the Shadow Control technique against the Titan Zombie, even though he would experience a backlash. However, Duke believed there was a reason David's request. Instantly, the Titan Zombie's body stiffened, tilting in mid-air, exposing its neck.

Seeing this, David didn't hesitate and retrieved a heavy machine gun from the space. "You beast! Today, I'll make sure you die! Do you understand the damage of a heavy machine gun?"

David relentlessly pulled the trigger, spraying bullets onto the neck of the Titan Zombie. Although he knew the neck wasn't the weak point of the Titan Zombie, it seemed to be the only breakthrough point compared to other areas. The blue-glowing heavy machine gun, like a bloodthirsty war god, ferociously showered the Titan Zombie's neck with bullets.

The Titan Zombie had no chance to move and its body was constantly hit by bullets. Wisps of white smoke rose from its armored skin as the heavy machine gun took effect. Seeing the results, David quickly signaled Duke to stop and retrieved ten high-explosive grenades from the arsenal!

At this moment, due to the force of the bullets, the Titan Zombie's body was pushed to the window, with no room to retreat. David pulled the pins of the ten bundled grenades while walking forward. When he reached the front of the Titan Zombie, he released all the grenades.

"Die!" David hung the bundle of high-explosive grenades on the Titan Zombie's body, his tone icy. Then, lifting his foot, he exerted all his strength and kicked fiercely against the Titan Zombie.
