Wang Lan and Sun Muchen were stunned on the spot.

"Well……"

Wang Lan pointed at the bomb and said incredulously, "This...you hid a bomb in your crotch?"

"You always have to leave yourself a way out, right?" Old Zhang explained as he searched for a suitable explosive point. "Whether I get bitten by an infected or torn apart by those monsters, it's not going to be pleasant either. I might as well leave myself a bomb so I can die a quicker death."

After he finished speaking, he looked at the brother and sister and said, "What are you standing there for? Hurry up and find a bomb site. Do you want to wait for those monsters to come back?"

The brother and sister snapped out of their daze and followed Old Zhang to find the explosive point.

In the distance, the massive army of animals pressed forward once more. Seeing that the final fortress had ceased its attack, they now ran even faster and roared even louder.

Wang Lan turned his head and finally saw the monster that had made the loud "mooing" sound. It was a huge and strong old bull. Its size was in stark contrast to the surrounding animals. Its skin was shiny purple, and its two horns on its head were enormous. It looked truly awe-inspiring.

Sun Muchen patted Wang Lan on the shoulder. Wang Lan turned around and heard Sun Muchen say, "Brother, I think the door of this fortress is tightly sealed. We can't put a mine in there at all. It seems we can only dig a hole under the door and bury the mine in it."

"good."

Wang Lan nodded repeatedly. Seeing the animal army approaching fiercely, he didn't have time to think of any foolproof plan. Since Sun Muchen had spoken, Wang Lan could only grab the Vajra Umbrella and plunge it towards the fortress gate, then begin digging holes with the umbrella one after another.

He was strong and fast, so he dug a deep pit in no time.

Old Zhang didn't waste any time. Seeing that the pit had been dug and Wang Lan had also left, he lit the bomb and threw it into the deep pit, then turned and ran.

But Wang Lan rushed over, opened the Vajra Umbrella, and pushed the excavated soil in to bury the bomb.

After a brief delay…

With a loud "boom!"

A blast of air, carrying soil, shot into the sky, causing the ground near the blast point to tremble violently. At the same time, the fortress gate slammed down with a loud crash, opening a small crack.

By this time, the animals had gathered around, but stopped at the outer wall of the fortress. It seemed that the bombing of the fortress had instilled a deep fear in them. They remained where they were, but dared not cross the line.

But the sheer force of this army terrified the three of them.

The group rushed to the fortress gate, but just as Wang Lan was about to insert the Vajra Umbrella into the crack of the gate to pry it open, he suddenly stopped.

He seemed to see the incredibly heavy door tremble slightly, though he wasn't sure if it was just his imagination.

Old Zhang was extremely anxious. "What are you doing? Why did you stop?"

Wang Lan was taken aback and looked at the fortress gate again.

It actually shook again, and the door opened a little wider. You could even hear a very soft knocking sound coming from inside.

Wang Lan frowned.

He suddenly realized that he had been wrong about some things.

Ultimately, the fortress remained indifferent to what was happening outside. Even when the most important border wall was breached, it did not intervene. Furthermore, although the fortress's defense system was activated just now, it stopped responding after the bombing.

Even when they blew up the door with a bomb, the fortress remained unmoved.

This is rather abnormal.

Could it be...

What happened to the final fortress?

Just as Wang Lan was thinking this, the fortress door trembled again, and this time, the door opened even wider, and the sound of banging on the door from inside could be clearly heard.

Old Zhang was stunned.

Sun Muchen frowned and looked over, listening intently. When the door trembled again, a sound like shouting came from inside!

"not good!"

Wang Lan only realized this at this moment, but it was too late. The moment he opened his mouth, the gate of the fortress was suddenly pushed open.

Wang Lan's eyes widened immediately. She grabbed Sun Muchen and squatted down, while Old Zhang gasped sharply, trembling as he covered his head with his hands and lay on the ground.

The moment the door was pushed open and slammed heavily to the ground, a chaotic and noisy roar suddenly erupted from inside. The roars were clearly human sounds, but at that moment, they sounded even more eerie than the monsters lurking on the outside.

At the entrance, countless people were crowded together, and no one could be the first to rush out of the fortress. Their gray-white faces had mouths stretched to the back of their cheeks, revealing their teeth, and their mouths were covered with bits of flesh and blood. Their clothes were tattered and discolored by blood, but the bright colors beneath the filth could still be seen.

They are the inhabitants of the final fortress!

But now, he has become an infected person!

Wang Lan glanced sideways, his mind drifting back to the residents of the final fortress in the past. But when he looked at the people now, who were like walking corpses, he was suddenly struck by a chilling sight.

The virus that infected these people seemed to be more severe than that of the infected people in the market. They looked more frantic and terrifying, with their skin and flesh festering and rotting. They screamed and shouted incessantly.

"slave!"

"Eat! Slaves!"

"They are our slaves!"

Upon hearing this, Wang Lan's eyes widened in shock.

He suddenly remembered that the infected people in the market had shouted things like "We are their slaves" and "They are back."

He immediately realized that the infectious virus did indeed originate from the final fortress!

Then it spread to the market!

Wang Lan's heart raced. He wondered if the final fortress had completely fallen. Otherwise, why would they not care about what was happening outside?

Just then, the roars of the infected suddenly intensified, and they all rushed out like a flood bursting through a dam, being pushed four or five meters away. The infected behind them also poured out one after another.

In just a few seconds, the continuously emerging infected people piled up into a small mountain!

As the three of them looked closely at the small hill, their hearts suddenly raced several times faster. The shock and terror were so intense that they got goosebumps all over their bodies.

Fortunately, these infected individuals did not seem to notice Wang Lan and his companions. After tumbling down the hill repeatedly, they quickly stood up and staggered toward the mutated animals.

Upon seeing so many people, the animals' instincts, amplified by the mutation, were immediately aroused and continued to surge.

This made them completely forget the terror of the final fortress defense system. With furious roars, they charged forward, rushing towards the infected!
