"Huff~" After swimming to the surface, Yun Qingran gasped for breath, almost suffocating.

"Ah!" After catching her breath, she suddenly realized that she was sitting on the Rock Cave King Serpent. Instantly, goosebumps rose all over her body, and she went into a defensive stance.

"Ugh..." The Cave King Serpent seemed to sense her fear, turned its head to look at her, and made a whimpering sound.

There was not a trace of violence or hostility in that voice.

"You're not going to bite me anymore?" Yun Qingran asked tentatively in a low voice.

"Woo woo..." The Cave King Serpent made a wooing sound again, appearing very docile.

Yun Qingran recalled that the Rock Cave King Serpent seemed to have stopped being hostile towards her after she kowtowed three times to the King of Fortune and the jade coffin opened automatically, and even saved her.

Could there be a mechanism on that prayer mat? If one sincerely kowtows to the King of Fortune, the jade coffin will open. If the jade coffin opens, it signifies that the tomb owner has accepted it, and the tomb's pet, the Cave King Serpent, will no longer attack and will even help her.

This King Fu Lu is truly a man of strong character!

"Ranran, get out of the way." Wuyuan stood on the shore, his foot on the bow, his hand on the string, the crossbow aimed at the Rock Cave King Serpent, ready to fire.

Despite the tense situation, only half an hour had actually passed. Wu Yuan quickly loaded his crossbow to rescue Yun Qingran.

"Wuyuan, no!" Yun Qingran quickly waved her hand at Wuyuan.

Seeing that Wuyuan was about to attack, the Rock Cave King Serpent coiled its tail, picked up a large rock from the shore, and hurled it at him.

"He is my friend..."

Before Yun Qingran could finish speaking, the Cave King Serpent moved and quickly darted into the water. Reflexively, she grabbed its body and followed it into the water.

Yun Qingran initially held the Rock Cave King Serpent tightly with her eyes closed, but later she felt the Rock Cave King Serpent stop, so she slowly opened her eyes.

The scene before her eyes shocked and horrified her.

She rode on the back of the cave king serpent, floating in the middle of the water. There were also luminous pearls underwater, and the entire bottom of the water was shrouded in a soft pearly light, as if she had entered a dragon palace, which was beautiful and magnificent.

What is most surprising is that there is a huge stone gate in front of her, with intricate and gorgeous patterns carved on it.

Could the endless treasure of the King of Fortune that the boatman mentioned be inside the door?

Believe it or not, it's very possible!

Is she about to become incredibly rich?

Yun Qingran wiped the drool from the corner of her mouth and suddenly thought of a problem: with such great underwater pressure, such a heavy stone door could not be opened at all!

Moreover, the door seems to have a keyhole, meaning a key is needed to open it. The key should be the hand-sized key that was found in the jade coffin. However, she accidentally sank both the key and the Zhanlang Sword into the water, and their whereabouts are now unknown.

As she was thinking, the Cave King Serpent suddenly darted towards the bottom of the water, and just as she was about to lose her buoyancy and float to the surface, it returned, carrying the Wave-Slaying Sword and the key in its mouth, and handed them to her.

Yun Qingran pointed to the huge stone gate, then to herself and the key, as if to ask: Do you want me to use the key to open the stone gate?

The Cave King Serpent stared intently at her, and Yun Qingran had a feeling that its eyes were saying: Yes, what I mean is that you should use the key to open this stone door.

Snakes are clearly cold-blooded animals, with no muscles in their eyes and unable to control their expressions, yet Yun Qingran truly and genuinely sensed the meaning of the Cave King Snake.

Is this snake about to become a spirit?

No, no, I can't hold it in anymore. I'll worry about whether it becomes a spirit or not later. I need to go upstairs and catch my breath.

Yun Qingran patted the Cave King Serpent, then pointed upwards. The Cave King Serpent immediately understood and brought her to the surface.

The cave king serpent had just surfaced when a large crossbow bolt shot out. It was so fast that only a black shadow could be seen slicing through the air.

"Run!" Yun Qingran urged, patting the Rock Cave King Serpent.

Unexpectedly, the cave king snake remained motionless. When the crossbow was only ten feet away from it, it swung its tail and slapped the crossbow, sending it flying and embedding it in the rock wall, its tail trembling.

"Holy crap! That's incredible fighting power."

It was only then that Yun Qingran realized that the Rock Cave King Serpent had actually been hiding its strength all along. If nothing unexpected had happened, she and Wu Yuan would definitely not have made it out alive.

Wu Yuan was also surprised when he saw this. He had used all his strength in that crossbow bolt. If it were a person, they would have been torn to pieces by now. He did not expect that the giant snake could directly withstand the crossbow bolt and even knock it away.

The first shot missed, and the initiative was already lost. Moreover, Yun Qingran was on the King Serpent in the Rock Cave. If another shot missed, it was very likely to injure her.

Seeing Wu Yuan discard his bow and crossbow and use his lightness skill to walk on water, Yun Qingran quickly stood up, waved her hand from the Rock Cave King Serpent, and shouted, "Wu Yuan, the Rock Cave King Serpent is an ally now!"

Upon hearing Yun Qingran's words, Wu Yuan was stunned and landed on the water's surface to look at her and the Rock Cave King Serpent.

“Go.” Yun Qingran patted the Rock Cave King Serpent, which obediently swam towards Wuyuan.

The cave king serpent obediently allowed Yun Qingran to step on it, showing no sign of ferocity, but rather appearing very docile.

"What's going on?" Wu Yuan's body tensed, ready to fight at any moment.

"The owner of this tomb is the King of Fortune of the Great Qi Dynasty. When I was being chased, I climbed onto the jade platform and kowtowed to him three times. I don't know why, but his jade coffin opened. Then it stopped biting me and became very obedient to me." Yun Qingran pointed to the cave king snake that served as her mount at her feet and grinned, revealing her small white teeth.

"What a stroke of luck." Wu Yuan breathed a sigh of relief as he looked at the harmonious scene between the man and the snake.

He was really scared just now.

"Look, dragon bones." Yun Qingran presented the dragon bones as if they were a treasure.

Upon seeing the dragon bones, a glint of light flashed in Wu Yuan's eyes. If he could gather all nine medicinal herbs, Yun Qingran could refine the Nine-Turn Rejuvenation Pill, and he could survive.

"Look, there's another sword. It's called the Wave-Slaying Sword. It's lightweight, sharp, and easy to carry." Yun Qingran took out the Wave-Slaying Sword and swiftly demonstrated a few moves.

This sword is simply the sword of her dreams!

As for the key to the stone gate, Yun Qingran didn't take it out; she had just secretly hidden it in a hidden compartment of her bag.

Behind the stone gate is very likely the gold and silver treasures hidden by the King of Fortune. Human nature cannot be tested in the face of great wealth. What if Wu Yuan is ruthless and kills her for the treasure?

His grandfather in a past life once told him that the two things one should never look directly at are the sun and the human heart. One should have good intentions, but also always be vigilant about human nature!

"It's good that you're alright." Wu Yuan lightly touched the water with his toes, flew behind Yun Qingran, and stepped onto the Rock Cave King Serpent.

"Woo woo..." The Rock Cave King Serpent shook its body unhappily, as if it was very unhappy that Wu Yuan had landed on it.

"Good boy, let's go back to shore," Yun Qingran patted it soothingly.

The cave king serpent stopped being temperamental and swam towards the shore.
