It's already afternoon, and they haven't eaten or drunk anything since yesterday afternoon. But they kept moving forward. Mei Sefu carried Xiao Ke on his back, and the sweat on his face kept dripping down. The little guy in the cage was also lying quietly in the cage at this time, quietly watching everyone continue to move forward.

They walked on for a long time, and found that there was no way out. For in front of them was a tall cliff, and they were standing at the bottom of the valley. The cliff was so high that they couldn't see the edge, and it was probably impossible to get out of here.

The first thing Wells did when he saw the cliff was trying to walk in the direction behind him. When he found that they could go back normally, the uneasiness in Wells' heart subsided.

"You see, there's a cave here. Su Rui was the first to discover a cave on a cliff face, and there were steps outside the cave. They can walk up the stairs from the bottom of the valley slowly, but the stairs are narrow enough for one person to climb up. If they were not careful to climb, they would fall to the bottom of the valley, and the cave was so high that if they fell from such a high position, they would be crushed to pieces.

"I don't think we should all go up there, and in case there's an emergency, everyone should have a helper down there. Wood looked around, there was only one cave in the cliff, and the little butterfly flew to this place and stopped flying, and Professor Theye must have been in that cave. Considering everyone's safety, Wood felt that he and Wells should go up and check the situation before making a decision.

"I'm going with you. Su Rui said with great certainty that Wood.

"Alright then, then the three of us will go up together, and if Professor Theye is really there, we'll let you know. Messevo wanted to go with Wood, but Wood thought it better for him to stay and take care of Xiao Ke.

Wood walked at the front, the staircase was very narrow, and they had to concentrate to keep their bodies balanced on the small staircase. If they are not careful, they will fall.

Su Rui walked in the middle position, and as they walked up the steps step by step, Su Rui only dared to stare at Wood's back, not dare to look down.

"If you're scared, look up, don't look down. Wood said to Su Rui behind him, he still glanced down, and a chill suddenly rose in his heart, he didn't have to look back to know that Su Rui must be very scared at this time.

"Don't worry, I won't be afraid, I'm still waiting to rescue Professor Siye. I wonder if Professor Siye would be touched to know that we were so brave and fearless in order to save him. Su Rui deliberately laughed, although Wood did not look back, she could also feel that Wood was also very nervous at this time.

"Yes, he will be grateful, I don't know what to say. Wood said with a smile, as if they had seen Professor Seyer's emotion by this time. Wood looked up and saw that they still had a long way to go, and the steps got steeper and steeper, until at last they had to climb up with both hands and feet.

Because she hadn't eaten for a long time, Su Rui's hands kept shaking, and Wells also felt a little exhausted. But when he saw that Su Rui was still gritting his teeth and persevering, he didn't feel tired anymore.

"We're almost there, hold on a little longer. Wood looked up, and he had already seen the cave, the entrance of which was so dark that he couldn't see inside.

Upon arriving at the cave, Wood lit the torches, and the dark cave suddenly became bright. Because the light looked very dazzling, some black bats flew out of it. These bats flapped their wings, and their shadows cast on the stone walls under the light of torches, making them look eerie.

"It's horrible that there are so many bats in there. Although Su Rui said that she was afraid, she did not stop at her feet, and followed behind Wood, walking forward unhurriedly. The air in the cave was as humid as outside, and Wells reached out and touched the stone wall, which was moist and cool. It seems that water often flows down from above, and Wells guessed that there must be a river passing by on this cliff.

They hadn't been walking long before Wood felt the stone path turn to sand beneath his feet. Wood was surprised by how there could be sand in such a cave, and he crouched down and lit the way under his feet with a torch.

At some point, the road under your feet turned into sand, and the sand was so fine that if something accidentally fell into it, you would never be able to find it again.

"The road ahead is a fine sand road, and if we continue to go forward, we will probably get stuck in the sand, which will be dangerous. Wood grabbed a handful of fine sand, which did not linger in his hands, but quickly slipped between his fingers.

"The sand is so fine that you can't hold it at all. Su Rui also grabbed a handful of sand, but the sand was like flowing water, and no matter how hard they tried, they couldn't catch it.

"It's strange that there is so much sand in the cave. Wells crouched down and put his hand into the fine sand. Unlike the surroundings, the sand is warm and dry.

Suddenly, Wells felt as if he had touched something hard, and he quickly scooped it out of the depths of the sand.

"This is?" Wells looked at the short sword he was holding in his hand, and his heart shook. From the appearance of this sword, you can know that this must not be an ordinary sword. Wells pulled the sword out of its scabbard and found a very ancient pattern carved into it. These patterns are like vines, wrapped around the blade, which means that it is a sword without a blade, because the blade is wrapped all over the sword with that ancient vine-like pattern. Wells looked at the scabbard again, and the scabbard was the kind of scabbard that didn't have any pattern.

"I think I've seen this sword somewhere. Wells studied the sword as he thought back to the book he had seen it from.

Although Wells couldn't remember for a moment which book he had seen it in, he was sure he had seen it with a sword like this.

"This sword is strange, it's the first time I've seen something like vines wrapped around it. Since there are so many things wrapped around the sword, how can it be used as a weapon? Su Rui was sure that this sword did not have any lethality at all.
