Crossing the wilderness to survive, starting with a broken kitchen knife.

The three-headed monster endured the pain, turned around with the battle axe and swept towards Zhang Shi's head. Zhang Shi held the kitchen knife with both hands, squatted to avoid the attack, and chopped hard, directly cutting open the monster's chest. In an instant, a large amount of filth like mud gushed out, and the monster was seriously injured and kept retreating.

"Boom!"

There was a huge earthquake on the ground.

Zhang Shi knew that it was the sound of their fighting that attracted the earth beast, but at this moment he was overwhelmed by the death of Zhang Dazhuang and did not intend to slip away. Instead, he wanted to kill the culprit in one go.

"Pfft! Pfft!"

Before Zhang Shi and the three-headed monster could make a move, a large group of black giant lizards suddenly emerged from the ground where they were fighting. This was the first time Zhang Shi had seen such a strange reptile, and his mind unconsciously associated it with the alien.

The giant lizards appeared without further ado, attacking everyone present. Even though the ground was still shaking violently, the giant lizards moved as if it were flat ground, moving at breakneck speed. Zhang Shi's center of gravity was unstable, and he could only retreat, choosing to avoid the attack.

Faced with the sudden onslaught of black monitor lizards, the battle situation instantly became more complex and critical. Zhang Shi retreated, observing the lizards as they moved swiftly. Their skin was as hard as iron, their movements were agile, and they continuously sprayed a corrosive liquid from their mouths. Once contaminated, even their equipment would be vulnerable, quickly corroding and leaving holes.

"Everyone be careful, these guys are not simple!" Zhang Shi reminded his teammates loudly, and at the same time used Shadow Step to dodge flexibly in the narrow space, trying not to have a head-on conflict with the giant lizard.

Zhao Feng swung his battle axe, creating a fierce storm to try to stop the giant lizards' attack, but their sheer numbers quickly dispersed his strength, making it difficult to mount an effective defense. Wu Qing quickly cast a series of defensive barriers to protect herself and her teammates from the corrosive fluid, while simultaneously unleashing offensive spells to slow the giant lizards' advance.

Ge Dalong used ice magic to condense a thin layer of ice on the ground, slowing down the monitor lizards' movements, but this was only temporary. As the monitor lizards continued to adjust their pace, the ice was soon broken by them.

At the same time, the ground shook more violently. In an instant, the area where everyone was located formed an almost 60-degree angle, and everyone fell uncontrollably towards the bottom.

Zhang Shi struggled to insert Lao Duan diagonally into the ground and hung it on the high slope. Only then did he see clearly that they were actually in the mouth of a giant creature.

"Is it an earth beast?"

Looking at the huge mouth that was bigger than the entire City Lord's Mansion, Zhang Shi was completely shocked by this scene.

Seeing that everyone was about to die in the monster's huge mouth, Zhang Shi was shocked to find that there was a golden light flashing in his backpack.

Zhang Shi, grasping at a lifeline, searched his backpack and discovered the source of the golden light was the golden token, given to him by Chen Beipan. It was said to unlock the ultimate secret of the secret realm. Zhang Shi took the token in his hand, and its light grew even brighter, enveloping him in a golden halo. However, this did not alter his current situation. The beast's maw closed, swallowing everyone. The land of the Fog City fell silent, as if nothing had happened.

Zhang Shi was awakened by a dazzling golden light. He found himself in an enclosed space. The entire space was only five square meters in size, and the height was barely enough for Zhang Shi to stand up.

Zhang Shi looked at the token that was still glowing in his hand, and was not sure what situation he was in. He clearly remembered that he was swallowed by a creature that looked like a ground beast. What was happening now?

Thinking of the earth beast, Zhang Shi felt a headache. He clearly remembered that Ge Dalong and Wu Qing killed it with the zombie virus, and the system's task also confirmed this. However, he still encountered the earth beast afterwards. Zhang Shi guessed that there might be more than one earth beast under the Fog City.

Zhang Shi tried to use the teleportation function of the Fog City and the system's built-in evacuation copy function, but found that neither of them worked. He knew that he was trapped.

After quietly putting the token into his backpack, Zhang Shi casually took out an oil lamp and touched the wall with his hand, only to find that it was all dirt. Zhang Shi picked up a piece of dirt with his fingers and used Dingzhen to identify it, finding that it was ordinary soil, nothing special.

Zhang Shi suddenly thought that the earth beasts lived underground in the Fog City, and he was probably in a space somewhere under the Fog City.

Zhang Shi frowned and opened the system panel, discovering that his teammates were all alive, with no apparent casualties. He used his contract ring to sense Chen Beipan's condition, confirming he wasn't dead either. The connection between them was even stronger than during their previous exploration.

Zhang Shi cheered up, took out the old Duan and started digging along the upper diagonal direction. Unfortunately, the blade of the old Duan was too short and the digging efficiency was not high. Zhang Shi then took out the shovel and started digging a tunnel in this confined space.

Thanks to his superhuman attributes, Zhang Shi worked very efficiently, and soon he had expanded the space to the size of a room. However, as the work progressed, Zhang Shi felt that the space was getting more and more stuffy. It seemed that the ventilation in the cave was poor and the oxygen content was very limited.

Zhang Shi gritted his teeth and continued digging diagonally upwards. He knew that time was extremely precious. If he couldn't save himself, he would probably suffocate to death in this earth cave.

Just as Zhang Shi felt his strength gradually draining away and his breathing becoming difficult, his shovel suddenly struck something hard with a clang. Delighted, he sped up his movements, and soon a hole, barely wide enough for one person, appeared before him.

Zhang Shi probed with his hand and found that the material of the cave entrance was similar to the buildings in the Fog City. It was hard and without any gaps, as if it was an integrated structure.

Zhang Shi went out without hesitation. Not long after, the view in front of him suddenly opened up to a huge underground cave. The air was filled with a faint earthy smell and an indescribable ancient atmosphere.

Zhang Shi explored around with the light of the oil lamp, but did not gain any useful information. However, there was air circulation here, and it seemed that there was a channel connecting to the outside world.

Zhang Shi tried to dig the top of the cave with a shovel, but found that the top of the cave was very solid and it was not realistic to dig it with his old knife. So he postponed the digging and started digging along the junction of the soil and the cave entrance. Unexpectedly, Zhang Shi dug up something within a few minutes.

A battle axe fell from right above him, and the scattered soil poured into the gaps in Zhang Shi's armor, covering him with dust.

"Bah!"

Zhang Shi picked up the battle axe and found that it was Zhao Feng's life-threatening battle axe. He was delighted and immediately dug upwards even harder.
