Earth's catastrophe, crazy black crystals begin to wreak havoc

Hibart's eyes flashed with greed: "The treasure in this treasure box is so rich! We can hide it secretly and take it away after we successfully make the antidote."

Mark seemed a little hesitant: "Although these treasures are very tempting, our goal is to treat the Bigfoot virus, and we cannot deviate from the mission."

Hibart clicked his tongue and said, "Mark, you are always so serious. However, you are right. The most important thing is that we must focus on finding the antidote materials."

They gently closed the treasure box, hid it behind their backs, and turned around to continue looking for clues to the secret passage.

Finally, in a broken stone slab, they discovered tiny, almost invisible keyholes.

Hibart excitedly patted Mark on the shoulder: "See? These keyholes must be the key to opening the next secret passage! We need to find the corresponding key."

Mark was full of expectations: "Then let's start looking for the corresponding key. Don't let the treasure box tempt us this time."

The two began to search carefully around the cave. Hibart carefully observed the patterns on the wall, trying to find clues.

"Mark, I found some ancient texts here, which may be corresponding hints. Please help me write them down."

Mark immediately took out a pen and paper and concentrated on recording the ancient words Hibart said. They work together to piece together the correct password.

While they were thinking about the password, Hibart suddenly saw a part of the stone with ancient writing on it.

"I saw an agate stone handle with a small key inlaid on it. This must be the corresponding one!"

Mark approached excitedly, carefully picked up the stone handle, and gently inserted it into one of the keyholes. With a "click" sound, they saw the entrance to a secret passage, leading to a deeper cave.

Hibart stretched out his thumb towards the secret passage: "Great, Mark! You are my good partner! We have to walk in quickly and see what is behind the secret passage."

Mark raised his eyebrows: "Yes! Hibart, I hope we can successfully find an antidote material."

They stepped into the dark passage, looking forward to the challenges and discoveries of continuing adventures. In this suspenseful and progressive reasoning, accompanied by humor and the tacit understanding of the team, Ouyang Yuyan, Hibart and Mark will continue to work hard to find the remaining materials and create an antidote for the Bigfoot virus.

The secret passage was winding and steep, and the torches on the wall cast a faint light, illuminating the road ahead of them.

Hibart looked around warily: "There seems to be something wrong with the atmosphere here. We have to be careful, there may be trouble waiting for us."

Mark tightened the sword in his hand and said warily: "That's right, Hibart, we can't take it lightly. We must always be vigilant."

They went deep into the secret passage, their steps slow and cautious.

Ouyang Yuyan looked up at the rock on the top and sighed secretly: "This cave is really impressive. It seems that making the antidote is not easy. We still have many difficulties to face."

Hibart felt a little excited: "Yes, everything is exciting! I like this sense of adventure. It feels like I am in an epic adventure movie."

Mark joked: "Don't let your imagination lead you astray, Hibart. We must keep our mission in mind and focus on finding the next antidote material."

Hibart laughed loudly: "Haha, Mark, you are too serious! Life is short, why should we be so cautious? We must seize every moment and enjoy the adventure!"

Ouyang Yuyan smiled and said: "Hibat, although you are right, we really need to find the next material as soon as possible. Time is life."

They continued moving forward and finally came to the end of the secret passage.

Two passages appeared there, one was three-dimensional and shaped like the letter T, while the other was narrower and led to a dark room.

Mark frowned and hesitated: "Which way is the right way? What should we do?"

Hibart gave a thumbs up: "My wisdom is needed to solve this problem! Mark, do you believe in my reasoning ability?"

Mark shook his head and smiled: "Hibart, I don't believe your reasoning so easily, but I dare to try my luck."

Ouyang Yuyan patted Mark's shoulder lightly: "Don't worry, we can find the answer through observation. Let each of us explore the two passages separately to see if there are any clues."

Hibart said excitedly: "What a great idea! Let everyone become a mystery hero!"

They decided to act at the same time, Hibart entered the wide T-shaped passage, and Mark entered the narrow passage.

Hibart walked some distance along the passage, and suddenly, he saw the words carved on the wall.

"Mark! I found some clues!" Hibart shouted excitedly.

Mark responded from the narrow passage: "Me too! There are some words carved on a wall too!"

Hibart said eagerly: "We need to communicate and see if there are any relevant clues!"

Mark and Hibart quickly described and compared the writing on the wall and finally discovered what they had in common.

Ouyang Yuyan focused their attention: "I noticed that the words on the walls of the two passages mentioned time and choice. Maybe this is a hint."

Hibart blinked: "You are right, Ouyang Yuyan! Time and choice, then maybe one of the channels refers to the limited-time choice."

They start to think and the concepts become clearer.

Mark said excitedly: "I understand! The word 'limited time' in the word gives us a clue, and the narrow passage just gives people a sense of time urgency. We should take the narrow passage!"

Hibart nodded and praised: "Mark, you are great! Your reasoning ability exceeds my imagination!"

They are approaching their goal step by step, constantly overcoming difficulties, and firmly believe that as long as they work together, they will eventually find an antidote to the Bigfoot virus. In the darkness, they continued to move forward.

There was an unsettling atmosphere in the dark room, and everything was almost completely invisible.

Hibart whispered, "It's really dark in here. We need to find a way to light up the room."

Ouyang Yuyan thought nervously: "I remember that there was a special luminous stone before, which might be used for lighting. We need to brainstorm ways to find it."

Mark groped the ground and suddenly touched a smooth object: "I found it! It feels like a luminous stone! Take a look, maybe it's what we need."

Everyone looked at Mark's palm and saw that it was indeed a luminous stone.

Hibart said excitedly: "Great! Let's light it up quickly and see the environment of the room clearly."

Mark squeezed hard in the darkness, and the luminous stone emitted a dazzling green light, illuminating the entire room.

They saw a treasure chest in the center of the room, glowing faintly, as if waiting for their arrival.
