If there were any gold and silver treasures, valuable magical items, or even beautiful women behind the door, Dip and Kai would not be surprised. But to their amazement, they actually ...... Nothing was found.

Dipu and Kei saw that behind the door was not a secret room or a secret passage at all, but a naturally formed karst cave. The cave is more than two people high, and stalactites grow on top and bottom. The entire cave also glows with a faint fluorescence, so you can see the scenery inside the cave vaguely.

And at the bottom of the cave, a dark river flows. This dark river does not flow much, and it seems to be the source of the fountain in the castle. However, seeing such a large cave, you can also imagine how magnificent the fountain was in the past.

Caves, dark rivers, fluorescent, strange rocks...... , what a beautiful landscape. But they did not come to travel, but to explore, or to make a fortune. So seeing such a natural scenery, both of them were somewhat disappointed.

"Why?" asked Kai subconsciously looking at the strange stalactites in the cave.

In fact, this is also the question of Dipp. The design of the Peron Magus turned out to be just a natural cave, and there was nothing in this cave, which would make people's minds full of question marks.

"Let's see!" Dip guessed, "maybe it's just to give the people in the castle a way to escape." ”

"Hmm!" Kye nodded. He took the torch and took the lead along the dark river, and shone it up and down, left and right, to see what was going on here.

Dip followed closely behind, also holding torches up and down, left and right. The two of them walked slowly along the dark river, towards the upper reaches of the current.

But it hadn't taken a few steps before Dipu remembered how he felt. He focused his attention on himself again, and immediately noticed that the feeling was much stronger.

With the sense, Dipp's attention was focused on that feeling. So he staggered the direction and took a few steps in the direction of induction.

The cave is actually not wide, so after walking a few steps, Dipu came to the dark river. By the light of torches and fluorescents, Dipu observed the dark river.

The dark river is a bit deep, and it looks like the river has been washed over many years. However, the water is crystal clear and the water quality is very good. Oddly enough, there wasn't anything at the bottom of the river, just a few small fish swimming around.

Dipu was even more puzzled, his feeling must be in the direction of this dark river, could it be from these fish? So he crouched down, stretched out his torch, and carefully observed the fish, but found that they were no different from the other fish. And the direction of his induction is also a little different from the direction of those fish, which is in the direction of the lower reaches of the dark river.

"What are you doing, have you found anything?" Kui finally noticed Dipp's strange behavior, and he turned around.

Dipu didn't answer, he just moved the torch in the direction of the lower reaches of the Dark River.

But with this move, Dipu felt a shadow quickly swim from the bottom of the river, and his own feeling suddenly reached its peak. Before Dipu could react, the shadow swallowed the fish at once, and then the shadow leaped out of the water and pounced on Dipu.

It was lightning fast! Dipu did not react at all. When he felt a fishy breath in his nose, he felt that the clothes behind him were pulled vigorously, and Dipu flew out backwards. Then the eye in his eyes saw Kay fly up.

"Ahh

"Poof!"

"Bang!"

With his mind blank, he fell to the ground with a heavy fall. When he hurriedly got up, he saw that Kai in front of him had knocked the shadow into the water.

Dipu hurriedly grabbed the bayonet sword that had fallen to the side. And Kai also took the opportunity to retreat. He pulled Dipp back a few steps, leaving the river for the time being. There was another noise in the dark river, and then a lizard-like monster slowly climbed up.

"What is this, what is it?" cried out Kay in horror.

The monster was more than a human length, and the scales on its body were colorful. Although it crawls like a lizard, there are two small fleshy wings on both sides of its body, and there is a sarcoma under its throat, which is not a common magical beast on the continent at all.

"Whatever it is, kill it!" said Dipp, too, loudly. In this way, he covers the fear in his heart.

"I can't do it!" shouted Kai again, "and I hit it a few times with all my might, and it didn't hurt. Its scales are too hard. ”

"Then run!" cried Dip. Looking at the movement of this monster crawling on land, it is not too fast. If you hurry, you should be able to escape to Shimen.

"Good!"

Kay immediately wanted to put away his two-handed sword. Unexpectedly, the demonic beast seemed to know their thoughts, and its body suddenly exploded, like a gust of wind, it burst in front of Keyi, and opened its mouth to bite off Keyi's face.

"Not good!" Chai cried inwardly.

Since he had already made the action of retracting his sword and running away, and was suddenly attacked by this demonic beast, Kay could not keep up with the movement of raising his hand and waving his sword. He could only swing his sword as far back as he could, trying to lighten his injuries.

At that moment, the first man stepped forward and stabbed the beast in the head. With a "snap", the stabbing sword broke, but the force made the head of the demonic beast deviate. In this way, Kayi's two-handed sword also arrived in time. The two-handed sword slashed heavily into the beast's neck, and the beast was slashed in the air and fell to the ground.

But the monster rolled on the ground and got up nimbly again, without any injuries. The rolling eyes were staring at Dip and Kui, with a fierce look.

"It's so hard!" said Dipu as he threw away half of the broken sword in his hand. Then, regardless of whether it was useful or not, he released several faint small fireballs in a row towards the demonic beast.

"Bang Bang Bang!"

The small fireballs landed on the monster's body one by one. Unexpectedly, the small fireballs that these low-level swordsmen could resist caused a cry of pain from the demonic beast. When the fireball dispersed, I saw only a few focal points on the scales of the demonic beast, and even a piece of the scale was burned through, revealing a small piece of red and tender skin.

Dipu immediately shouted excitedly: "This monster's physical defense is very strong, but the magic resistance is too low!
