"Wait a minute!" Lin Yu suddenly had a flash of inspiration and said solemnly.

"Hmm, what's wrong?" Yurou stopped and looked at Lin Yu.

Lin Yu walked to the stone table chessboard, looked at the chess pieces on the chessboard with a bitter expression, and wanted to find something: "This game of chess is weird!"

Yu Rou was also shocked when she heard this, and she also walked to Lin Yu's side and looked at the chessboard, and asked coldly, "What do you see?"

Lin Yu carefully looked at the chess game again, and said with some uncertainty: "This chess game is a little peculiar. The layout of the field turned out to be exactly the same as where we walked around when we entered the cave. And judging from the trend of this chess game, if you take the passage ahead, it will be a dead move. So ......"

Yurou listened to Lin Yu's explanation, and her heart was also shocked, and she looked at the dim and headless tunnel outside the stone room, and intercepted: "So the passage in front of us is dangerous?"

Lin Yu nodded: "That's right." ”

Yu Rou glanced at Lin Yu, and her figure suddenly appeared in front of the tunnel, and the next moment the Ice Spirit Sword suddenly came out of its sheath, and a stunning sword light flew towards the tunnel on the ground. Soon, in addition to a deep sword mark on the ground, layers of thick and cold ice suddenly condensed on the ground.

The next moment, there was silence around the tunnel, and nothing happened.

Lin Yu looked at the cold and silent passage in front of him, his mind turned quickly, and he secretly thought, "It's rare that my reasoning is wrong?"

Just when Lin Yu thought that he was wrong, suddenly the ground shook, and then the dark tunnel in front of him collapsed at a speed visible to the naked eye, and it was reduced to nothing in just an instant.

Although they had foreseen it, the two were still a little surprised.

If I hadn't discovered it earlier, I would have entered the tunnel directly, and now I'm afraid there would only be no return.

Yu Rou looked at Lin Yu with palpitations, and couldn't help but be impressed by him.

The two returned to the stone table, looking at the black and white chess pieces on the chess game and fell into deep thought.

"How do you know so much about Go?" Yurou broke the silence.

Lin Yu had memories flowing in his eyes, and said with a smile: "It was someone else who taught me." She said that there are many dangers in the rivers and lakes, and there are many things that must be mastered and understood, and this game of Go is one of them. ”

At this moment, Lin Yu's mind was filled with the peerless smile of a woman in purple.

"No wonder. Do you see any clues now?" asked Yurou.

"According to the current situation of this chess game, Kuroko can only play like this. And here corresponds to...... It's behind the stone bed!" Lin Yuleng looked at the chess game for a while, and suddenly had a flash of inspiration and said excitedly.

"You mean there's a mechanism in that stone bed?" asked Yu's beautiful eyes.

"Yes, the passage is just behind the stone bed wall" The corners of Lin Yu's mouth rose slightly, and his figure came to the stone bed with a blur, and then the black qi of his fist churned, and he smashed towards the wall with a punch.

There was a loud "boom".

Suddenly, the wall shattered, and when I looked at it, I saw a long, dark and invisible tunnel gradually emerging behind the wall.

Yurou glanced at him, nodded to him, and walked deeper, Lin Yu followed behind her, this time she didn't go far, and entered a spacious place again. However, unlike the previous stone chambers, they are all hidden traps.

Fortunately, Yu Rou was calm and cautious, so these organs did not cause them any harm. Both of them breathed a sigh of relief.

In the next tunnel, there were strangely shaped stalactites everywhere, and Lin Yu and the others only walked around the tunnel for a while, only to see Yurou who was walking in front suddenly stopped.

And almost at the same time, Lin Yu suddenly found that the demonized true spirit in his body seemed to be a little restless, as if he had met an old friend or acquaintance he hadn't seen for many years, with endless thoughts and attachments.

Lin Yu looked forward in surprise.

At the bottom of the cave is a smooth stone wall, as if paved up. There is a tunnel on each side of the stone wall, leading to an unknown place, but under this stone wall, there is a bluestone stone room, which is different from the stone rooms at the beginning. And on the stone bed in the stone chamber there was a skeleton, sitting upright, sitting quietly.

And the demonized true spirit in Lin Yu's body, facing this skeleton at this moment, actually had a black aura on his body.

Yurou stood in front of her, not noticing Lin Yu's strange expression and the changes in the surface of his body. And Lin Yu was also taking this opportunity to quickly suppress the true spirit on the surface of the body.

After doing all this, Lin Yu fell into thought about the strange phenomenon that had just happened.

And how could Yu Rou be afraid of a skeleton, she stepped forward at the moment, looked at it carefully, and after a while, turned her head and said to Lin Yu: "Maybe this is the true demon who fell here thousands of years ago after Megatron!"

Lin Yu, who was contemplating, was suddenly startled when he heard Yurou's words, and then smiled embarrassedly and said, "It seems that it should be." But no matter how powerful he was then, he has now turned into a skeleton. ”

Yurou glanced at him and said, "too!"

Lin Yufan was stunned for a moment, then looked at the three passages in front of him, and said, "There are two passages ahead, why don't we choose one of each to go in first?"

"Okay!" Yurou finished and walked straight to the passage on the right.

Lin Yu glanced at Yurou, and then walked in with the passage on the left.

The tunnel that Lin Yu was in was no different from the road outside, deep and quiet, looking into the distance, it was almost dim, and the road seemed to be relatively long, I really couldn't figure out how the true demon had built such a huge project back then.

However, the true demon is so powerful, this huge project is naturally not completed by him alone.

After walking like this for a while, Lin Yu suddenly noticed that the front was gradually brightening, Lin Yu was overjoyed, and stepped forward with a quick pace. I saw a soft light emanating from the end of the tunnel ahead, which was exceptionally clear in the darkness, like gentle tentacles, tempting the lost.

Lin Yu took a deep breath, tightly grasped the ice sword in his hand, and stepped into the light.

Looking at Yurou again, this is also a road similar to the outer tunnel, the tunnel is dim and long.

After about a pillar of incense, Yurou soon came to an end and stepped into a stone chamber again.

This is a large stone room, with many weapons hanging on one wall, Yu Rou took a closer look, and her face first showed a look of great joy, but it didn't take long for her to involuntarily change to a look of disappointment.

I saw that there were labels on the weapons, and some of the words on them had long been blurred and had long been invisible. But the weapons that the real demons possess are obviously good goods. But the guns, knives, and swords hanging from them were all in tatters. Obviously, over the course of thousands of years, these once powerful weapons have been reduced to scrap metal and lost their aura.
