But why is there thunder here?

Wang Lan was completely baffled, but the situation was urgent and he didn't have time to think about it. He could only leave quickly, find Sun Muchen and Lao Zhang and leave as fast as he could.

Compared to these constantly evolving and mutating giant infected, Wang Lan seemed to think that the mutated animals were not so scary!

The rumbling thunder continued.

As the gears detached from the axle and fell downwards, crashing into other gears, Wang Lan felt that her ears could hardly bear the chaotic noise.

But the destruction caused by the giant infected only intensified.

The tentacled arms flailing about as if dismantling a gear assembly, and as the gear assembly above fell, the giant infected's tentacles seemed to automatically block it, knocking the gears away.

He then went after Wang Lan.

Wang Lan rushed into the steam engine group. The ruptured pipes made the steam even more concentrated. As soon as Wang Lan entered, he felt as if he were soaking in hot water. His breathing became difficult, and the steam and high temperature caused a lot of sweat to quickly gather on Wang Lan's forehead. The sweat streamed down and even flowed into his eyes. His steps slowed down involuntarily.

The giant infected rushed in right behind, caught up with Wang Lan, and instantly sent him flying.

Wang Lan slammed against the wall of a pipe and fell to the ground, only to find that the ground was covered with a large amount of water. Wang Lan gritted his teeth and got up. He saw that the water vapor was so thick that he could no longer find the location of the giant infected, and he could not even see a hazy shadow.

Even so, the roar of the giant infected was still clearly audible and echoed throughout the space.

At the same time, it seemed that the giant infected had started attacking indiscriminately again, with constant "bang bang bang" sounds echoing and "sizzling" sounds of steam erupting.

The temperature in the steam continued to rise, and Wang Lan felt obvious difficulty breathing, and even waves of dizziness came over her. However, all around her was a vast expanse of white, which made Wang Lan completely lose her sense of direction.

Wang Lan groped her way out.

Suddenly I heard Old Zhang's voice.

Faintly, one could also hear Sun Muchen's voice.

They were calling out their own names.

Although it wasn't a wise move for the two to come here, the current situation didn't allow Wang Lan to hesitate any longer. Hearing them calling his name again and again, he replied, "I'm here!"

As soon as he uttered the words, a large amount of water vapor rushed into his mouth and into his lungs. Wang Lan coughed violently, and the dizziness intensified. He felt the strength supporting his body in his legs gradually slipping away, and he was about to collapse when suddenly two figures rushed out from in front of him and helped him up.

Wang Lan squinted and saw that it was Lao Zhang and Sun Muchen.

Both of them were flushed, especially Old Zhang, who, despite being supported, was swaying from side to side and could hardly stand.

"Let's hurry!" Old Zhang said with difficulty, shaking the hemp rope wrapped around his waist. "Let's go back along the rope."

Wang Lan immediately understood.

Presumably, the two were afraid of getting lost, which is why they used ropes as markers.

Wang Lan nodded. Just as the three of them were helping each other to leave, a roar suddenly sounded behind them. They knew without a doubt that it was the giant infected that had come over. They just didn't expect it to appear at this time. The three of them subconsciously turned around to look.

A gigantic phantom appeared, radiating immense pressure, accompanied by the sound of wind being torn apart. A massive fist, encased in tentacles, emerged from the phantom and struck the three. Old Zhang pushed Wang Lan and Sun Muchen aside, but he himself failed to retreat in time, and the fist landed on him.

"ah--"

Old Zhang's screams rang out immediately.

Wang Lan, who had been pushed aside, stared wide-eyed. He vaguely saw Old Zhang's figure flying backward and shouted, "Old Zhang!"

Then he rushed over.

The giant infected figure appeared hazily in the water vapor. Wang Lan made out the position of the arm, raised the Vajra Umbrella, and smashed it down on the arm.

The giant infected immediately roared, but Wang Lan didn't stop. He withdrew the Vajra Umbrella and jumped towards the giant infected's head. At the same time, he gripped the umbrella with both hands. When the giant infected's head appeared in his sight, he swung the Vajra Umbrella and hit it hard on the head.

The Vajra Umbrella immediately bent and deformed, which shows how much power Wang Lan used in this attack. The giant infected's huge body was sent flying backward and disappeared into the water vapor.

Wang Lan landed on the ground and saw that Sun Muchen had also rushed over. Without even checking the damage to the Vajra Umbrella, he said to Sun Muchen, "Go find Old Zhang quickly, he must be seriously injured!"

Sun Muchen nodded blankly, as if Wang Lan had never been so anxious for anyone before. The two of them ran quickly in the direction that Lao Zhang had been sent flying and soon saw Lao Zhang lying on the ground.

Wang Lan helped Lao Zhang up and then discovered that Lao Zhang's chest was a bloody mess, and blood was gushing from his mouth.

"I...I'm not going to make it."

Old Zhang said in a trembling voice.

Wang Lan shook her head. "Speak less. You won't die. Immersing yourself in the red mist has greatly improved your physical condition. Don't worry, you definitely won't die!"

As he spoke, he helped Old Zhang up and looked at Sun Muchen, saying, "Let's go. The air here is too humid, and it's not good for Old Zhang's recovery."

Sun Muchen nodded and pulled on the rope to walk ahead, while Wang Lan helped Lao Zhang follow closely behind. The three of them quickly walked out of the steam engine group. The moisture in the air had decreased, but due to the giant infected's attack on the steam pipes, a large amount of water vapor was gushing out, and the steam had spread towards the reactor.

It wasn't until the three of them reached the reactor that they felt the moisture disappear, their breathing became easier, and the surrounding temperature dropped.

"etc…"

Old Zhang suddenly began to tremble violently. The wound on his chest made his face turn pale, and his legs went weak and he was about to fall. Seeing this, Wang Lan quickly and carefully helped him sit down on the ground.

Only then did Wang Lan realize that Lao Zhang's injuries were far more serious than he had imagined. His chest was severely deformed, with obvious bone damage, and his abdomen was covered in blood, with his internal organs even visible.

Wang Lan fell silent after reading it.

Sun Muchen sighed, unsure of what to say.

Old Zhang wanted to look down at his injuries, but they were too severe and painful. As soon as he made a move, he trembled uncontrollably from the pain.

"Wang Lan, Sun Muchen..."

After taking a few heavy breaths, Old Zhang looked at the brother and sister and said, "I'm not going to survive. That giant infected is still alive, and the Rippers below are still attacking relentlessly. Don't worry about me, let's go."
