Gu Xiao and Qin Yun looked at each other and decided to deal with this deformed monster together.

"This monster seems to be protecting something." Qin Yun frowned and noticed this detail.

Gu Xiao raised his eyebrows and looked at him: "That's right. I've made some progress. I can actually observe details."

Fang Qingcheng and Shen Suhua assisted Gu Xiao and Qin Yun from the sidelines.

"It is estimated that what this evil monster wants to protect is related to this secret realm." Fang Qingcheng speculated.

"But it doesn't seem willing to give up." Shen Suhua also expressed her thoughts.

Gu Xiao nodded in agreement with their analysis, but felt that things were not that simple.

This is the secret ruins that the Fang family has hidden for many years! How could it be destroyed just because of a mere monster?

And if the thing it wants to protect is really related to this place, why bother guarding it so hard?

"Maybe it's not afraid at all, let's kill it first." Qin Yun suggested.

Fang Qingcheng shook his head and denied: "Look at the surrounding environment, it is obviously a formation."

"This formation is not arranged by ordinary people, but is specially used to seal the energy of evil spirits to prevent them from leaking out and harming other living beings. If it is just an ordinary monster, but since it dares to stay in the secret realm, it must have something to rely on. That’s right.”

Fang Qingcheng's words made several people fall into silence.

After a while, Shen Suhua suddenly exclaimed: "Oh no!"

Everyone looked at her in unison.

Shen Suhua looked anxious and spoke very quickly about what she had just discovered: "Did you hear the sound of water dripping?"

Qin Yun shook his head, indicating that he didn't pay attention.

Gu Xiao frowned and recalled it, and there was indeed the sound of water dripping.

"It's not just the sound of water drops, but the sound is getting closer and closer!" Qin Yun added.

"Could it be..." Fang Qingcheng had a worried look on his face.

Gu Xiao and Qin Yun immediately turned around to look for the direction pointed by Fang Qingcheng, and soon found the bump.

It was a huge stone, about ten meters in diameter, and the groove was right in the center of it.

The surrounding area was completely empty, with nothing else but this huge boulder, but one could clearly hear the tinkling tinkling sound of water droplets falling.

As the clanging sound gradually grew louder, Gu Xiao and the others finally determined the source of the sound.

It was flowing from the cracks in the rocks. The water was fast and kept sliding down from the top of the boulders.

"Is it an underground river?" Shen Suhua guessed.

Fang Qingcheng nodded solemnly.

Qin Yun also thought of something: "Could it be that... this dark river is the rumored dark sea?"

The three of them looked at each other and saw the light of hope in each other's eyes.

"No matter what it is, we finally found a way to leave here." Qin Yun said with a sigh of relief.

Fang Qingcheng agreed, "Yeah!"

"I don't know how deep this underground river is." Shen Suhua said, looking at the underground river.

Fang Qingcheng narrowed her eyes slightly: "No matter how deep it is, it can't stop our belief in leaving the secret realm!"

Her tone was firm and high.

Qin Yun smiled and clapped: "Yes! We will not give up!"

Fang Qingcheng raised her hand to signal him to be quiet.

Qin Yun immediately fell silent.

Then Fang Qingcheng took two steps towards the underground river, then closed his eyes, as if feeling the situation of the underground river.

"The water pressure in the underground river is very strong. If you jump in hastily, you may be in danger." Fang Qingcheng opened his eyes and said.

Gu Xiao frowned, "So, we have to wait for the right opportunity."

Qin Yun nodded in agreement, "Well, at least we need to wait until the water pressure in the underground river weakens."

Gu Xiao sighed, "Oh, this is the only way."

"By the way, does the underground river have water pressure?" Shen Suhua suddenly interrupted and asked.

Fang Qingcheng nodded.

"Then can we penetrate the underground river before the water pressure weakens, so that we can leave here?" Shen Suhua suggested excitedly.

"Well, that's a good idea." Qin Yun agreed.

Fang Qingcheng shook his head in denial: "This situation should be unlikely. First of all, none of us know how wide the underground river is. If it is opened, we will not be able to swim across it at all?"

Shen Suhua's face suddenly fell.

Gu Xiao and Qin Yun also frowned.

"What should we do?" Qin Yun murmured.

"Do you still remember that evil monster's initial behavior?" Fang Qingcheng reminded.

"It seems to be protecting something..." Shen Suhua suddenly realized.

"Yes, what we have to do is destroy the things it protects."

Fang Qingcheng smiled coldly: "I have a trick, which is called removing the firewood from under the cauldron."

"What is it?" Shen Suhua asked impatiently.

"Do you want to try the 'Fire Dragon Technique'?" Fang Qingcheng asked with a faint smile.

"Okay, I can't wait for a long time." Shen Suhua said excitedly.

The other two people also nodded.

"In that case, let's give it a try."

Gu Xiao stood up and stretched his muscles.

"Don't forget to use the defensive shield!" Shen Suhua warned.

The three of them all made their own preparations.

"Boom——!"

Accompanied by deafening thunder, dense dark clouds in the sky, lightning and thunder, it was as terrifying as the end of the world.

As the black clouds rolled, thick bolts of lightning intertwined in the dark night, like ferocious beasts with teeth and claws.

"Coming!" Fang Qingcheng reminded in a low voice.

"boom!"

Lightning struck the underground river fiercely, and instantly exploded with thousands of feet of golden light, illuminating the entire underground river as if it were daytime.

Then the second, third, fourth...countless thick lightning bolts descended from the black clouds and struck hard on the underground river.

“Crackling——!!!”

The violent explosions were mixed with some miserable wails.

The lightning was so powerful that the evil monsters in the underground river were instantly blown to pieces, and even the water was evaporated.

The originally dark red lake water now appears strangely transparent.

Fang Qingcheng and the other three rushed over, and sure enough they found a round stone slab on the boulder in the center of the underground river, and ancient and obscure runes were carved on the stone slab.

"What is this?" Qin Yun looked at the runes on the stone slab in confusion.

"I don't know..." Fang Qingcheng frowned, "I've never seen such a font."

"Let's go up and have a look."

Qin Yun jumped up to the stone platform and looked down at the entire stone slab, but except for the runes, he didn't find anything strange.

"Have any of you seen such a pattern?" Fang Qingcheng asked.

"Let me take a look." Shen Suhua went over to check.

After a while, Shen Suhua said: "This should be a treasure map."

Fang Qingcheng nodded: "Yes, this is indeed a treasure map, but I don't know what this treasure map is."

"We have to do some research. If we can successfully take out the treasure map, then we can leave here." Qin Yun said happily.

They have stayed in this secret realm for long enough. If they delay it any longer, they may cause even greater trouble.

Fang Qingcheng also considered this.

She stepped on the stone slab and walked up the stone wall.
