The two groups of people went their separate ways. After waving and saying goodbye, they were separated by towering trees and stone walls!

"It's getting more and more gloomy as we go. Let's open the fourth envelope and take a look." Han Shui'er suggested. It was also pitch black inside.

"Yeah." Ye Moze nodded in agreement and opened the envelope...

There are a few words scrawled on the envelope: [Congratulations, you opened the fourth envelope. Did you see a few glass jars? There is a key to open the door of the cave. You only have 3 minutes! It’s not over yet.

Open it and the glass jar will explode! There is only one key among these hundreds. I wish you good luck! When you put your hand into the glass jar, the timer will start!]

"Only one of the hundreds of keys can open the stone door of the cave?" Wen Xueyan looked at the words on the paper and was a little startled, "How is it possible to find an accurate key in 3 minutes?"

Ye Moze looked at the two big jars, "Now we can only give it a try!"

"Betting on luck?" Zuo Moyan looked at Ye Moze, "We only have a few percent chance of winning!"

"Then we can only give it a try and try our luck!" Han Shui'er looked at the key in the glass jar, "I'm going to reach in and get the key!"

"Let's start!" After Ye Moze nodded, Han Shui'er quickly reached in and fished out several keys. Then the sound of [beep beep——] sounded, and they all knew that the timer had started!

Han Shui'er, who was holding the key, kept reaching into the big iron lock of the cave door, trying to use the key to open the cave door, but none of them was correct!

She threw the keys on the ground one by one, and then Ye Moze also brought a bunch of keys to open the door, but none of them was correct...

The few of them used wheel tactics and ran back and forth again and again...

Time ticked by, and Ye Moze stood there and suddenly stopped moving. They seemed to have overlooked something...

"What's wrong? Why isn't it moving? There are so many keys, brother!" Wen Xueyan doesn't want an explosion!

"We seem to have overlooked something!" Ye Moze took out the letter again and checked it. The other three people were still running between the jar and the cave door...

"Damn it! Why don't you have a key?" Han Shui'er looked at the keys all over the floor and ran to the glass jar again to get the keys!

"Shit!" Zuo Moyan also cursed angrily. There is no key to open the big stone door! Are their luck really bad?

"The glass jar will explode... When the time is up, the glass jar will explode? Explode..." Ye Moze looked at the words on the letter and muttered to himself!

"Ah! Time is getting less and less! We have to hurry!" Wen Xueyan quickly took the key and kept opening the stone door, but there was no big iron lock that could open the stone door!

Beads of sweat appeared on their foreheads, and the sweat dropped drop by drop on the muddy ground full of dead leaves... The towering trees around them blocked the shade, and there was no sunlight. The humid, dark and cold mountain forest actually

Will you sweat?!
