Two golden floorboards were stepped by the instructor's feet, and there was a large protruding lock in the middle of the wooden board!

"I've found something new!" The instructor shouted. Everyone was attracted by his cry of surprise. They saw the instructor standing at the top of the pyramid, looking down at his feet with a face full of shock, slightly trembling.

"What's going on?" Bai Long immediately rushed up. This small pyramid wasn't really that big, so Bai Long quickly climbed up. When he saw the lock on the top of the pyramid, he was dumbstruck.

Yang Yingsen and Li Xueyang immediately rushed over, the four of them stared blankly at the mysterious lock, what was it that was locked in such a deep place? No one knew, but from the looks they exchanged glances, they knew that the thing inside must be some kind of great secret!

"I already said that this place looks like an ancient tomb." Li Xueyang said, his eyes carrying a hint of surprise and speculation.

Ancient tomb? Li Xueyang's words once again caused everyone to speculate. If this small pyramid was an ancient tomb, then what would be locked inside? Was it a corpse or a great demon king that could be resurrected?

"I think it's better if we don't touch it for now." Yang Yingsen's eyelids constantly twitched. He clearly felt that something bad was about to happen.

"How strange, this lock actually doesn't have a keyhole!" Bai Long was surprised to find that he had looked towards the hidden door at the top of the pyramid.

Yang Yingsen also came closer to take a closer look. There was even a dent in what looked like a lock, it seemed like it was missing something, which made him think of a bridge in the movie. As long as he could retrieve a part of the lock, this ancient tomb would probably open!

"There seems to be something else missing. You guys go around the floor and look for it. See if there's anything like a dent that matches this lock."

Yang Yingsen reminded them, and they all started searching the ground without saying a word. The ironic thing was that the floor was filled with gold and silver treasures, yet they were all thrown around like trash. They had all opened their eyes wide, but they still could not find anything that matched the indentation on the lock.

The clanging sound of metal hitting metal caught the attention of a bug. It used its large eyes on the top of its head to keep probing, and other than the buzzing of its own kind, there seemed to be nothing else in this dark cave. Just as it turned its head, a hint of fire flashed across its eyes.

"Weng Weng ~"

The flying insects kept on chirping, and he kept touching them with the tentacles on top of his head. Gradually, more and more bugs noticed the weak light from below and decided to explore it in groups.

A group of bugs lined up orderly and arrived at the source of the light. They curiously looked at the narrow entrance in front of them. It was so narrow that only one worm could pass through at a time.

In the end, a bold bug flew out, interrupting all of his doubts. It slightly stirred its arms as it flew in, its mouth occasionally emitting a humming sound.

"Hey, have you guys found it yet?" Immersed in the middle of a pile of shining gold, Yang Yingsen finally raised his head and asked. He looked at Bai Long who was similar to him, who had dove into a pile of gold.

Bai Long shook his head in disappointment. He thought, since there was a lock, then the key couldn't possibly be hidden in such a conspicuous place. Bai Long felt that all he had done was useless work.

"The probability of the key being here is very low! I think it is very likely to be in the depths of the God Stone Cave! " Li Xueyang decided as she dejectedly threw away the pile of gold in her hands.

The instructor also nodded his head. It was very likely that this was the final secret of the God Stone Cave, and the depths of the God Stone Cave was only hiding a key. Thinking about this, he couldn't help but feel his heart tighten.

"Weng ~"

A strange buzzing sound came from the broken entrance. Yang Yingsen immediately looked over and saw a bug that was about the same size as a normal person observing them from the dark.

"This is bad!" We've been discovered! " Yang Yingsen shouted in shock. The insect seemed to have noticed that something was amiss and it kept on locking the door.

Suddenly, a hint of fear flashed across the insect's eyes. It turned out to be an invisible sword qi that was flying towards it at a fast speed. Before it could even scream, the insect had already dismembered.

Bai Long kept his sharp sword, his vigilance allowing him to finally let out a sigh of relief.

"Looks like we have to think of a way to escape." The instructor said calmly. He knew that the inertia of these bugs was usually done in groups, and the bug that just flew in was just a scout. Soon, this place would be filled with a bunch of crazy, life-threatening bugs.

Li Xueyang looked around. Other than the entrance that they had just entered from, there seemed to be no other place to escape to.

However, what was truly surprising was that those bugs did not shoot out as expected. Instead, they slowly crowded out one by one.

Bai Long lifted up his hands and jumped over, swiftly and neatly. Just like that, the bugs that he squeezed out with much difficulty were sliced into two by the merciless blade, and when he stopped to look at the entrance of the cave, he suddenly realized something.

"Hahaha, what good luck! These bugs have been blocked!" Bai Long laughed happily. The narrow tunnel only allowed one giant worm to pass through at a time.

Moreover, with the increasing number of corpses of the bugs, it would be very difficult for those huge bugs to squeeze in. Even if they had tried to squeeze in, they might not even be able to make it out alive, because Bai Long's sharp blade was already aimed at every bug that flew out of the cave.

"But, how are we going to get out later?" Yang Yingsen said worriedly. Seeing that the accumulated corpses had blocked the only exit completely, he started to worry.

"In my opinion, the one who should be worried isn't this, but those players up there!" The instructor said slowly. Once again, he turned into a transparent crystal person, his eyes constantly on the alert of his surroundings. It was because the huge commotion here might have alarmed the group of mysterious players who were searching for the Heroic Forest like him.
