Immortality Cultivation: I can use my clansmen’s energy and blood to add points.

Luo Chen's eyes flashed with excitement, and he said, "Then we must go and see it."

The two carefully crossed the lake and came to the island.

The light emitted by the crystal fruit shrouded the entire island in a mysterious glow.

Just as they were about to pick the crystal fruit, suddenly, ripples appeared on the lake and a huge water snake slowly rose from the lake.

Its body glowed with blue light, and its eyes shone with wisdom.

"Humans, why did you break into this forbidden area?" the water snake asked in a low voice.

Luo Chen and Qingshuang looked at each other and knew that they had encountered a powerful guardian again.

They replied respectfully: "We just came here by accident, hoping to pick some crystal fruit."

The water snake was silent for a moment, then said: "The crystal fruit is the sacred object of this swamp. Only those who truly have awe in their hearts can be recognized by them. If you can pass my test, you can pick the crystal fruit."

Luo Chen and Qing Shuang nodded in agreement, they knew this was a rare opportunity.

A hint of approval flashed in the water snake's eyes. It slowly swam to the edge of the lake, motioning Luo Chen and Qing Shuang to follow.

It led them to a flat boulder at the edge of a lake, with some ancient runes carved into it.

"This is the trial ground of the swamp. You must pass three levels to prove that your mind is pure and your strength is sufficient." The voice of the water snake echoed on the lake.

Luo Chen and Qingshuang looked at each other. They knew that this was a test and also an opportunity.

They took a deep breath and prepared to accept the challenge.

The first level was a test of the mind. The water snake asked them to sit on a boulder, close their eyes, and completely open their minds to accept the test from the swamp. Luo Chen and Qing Shuang sat down as instructed, and they felt a gentle force begin to penetrate their consciousness, trying to explore the depths of their hearts.

Luo Chen was the first to experience a series of hallucinations, in which he saw his past failures and setbacks, but he was determined and was not shaken by these hallucinations. Qing Shuang saw her desire for the future and her longing for her loved ones, but she also remained calm and was not swayed by these emotions.

After a period of testing, the water snake's voice sounded again: "Your hearts are pure enough and you have passed the first level."

The second level is a test of strength. The water snake requires them to show their strength and prove themselves through fighting.

Luo Chen and Qing Shuang respectively face two opponents transformed from water snakes, and they have to fight with all their might.

Luo Chen was facing a warrior made of water, who was agile and attacked fiercely.

Luo Chen waved his sword and fought against it. He used his speed and sword skills to cleverly avoid the attacks and look for opportunities to counterattack.

Qingshuang was facing a giant beast made of mud. It was extremely powerful and every attack it made was extremely destructive.

Qingshuang used her lightness skills and agile body movements to dodge the giant beast's attacks, while counterattacking with her weapon.

After a fierce battle, Luo Chen and Qing Shuang both successfully defeated their opponents.

The water snake nodded with satisfaction and said, "You are strong enough to pass the second level."

The last level is a test of wisdom.

The water snake asks them to unlock the ancient runes engraved on the boulder, which represent the secrets and power of the swamp.

Luo Chen and Qing Shuang observed the runes carefully and found that these runes seemed to be related to the symbols they had encountered in the swamp before.

They began to try to combine these symbols and find the patterns among them.

After some thinking and experimentation, they finally found the right combination.

The runes began to glow, and strange ripples appeared on the surface of the lake.

The water snake said with satisfaction: "Your wisdom is enough to unlock the secrets of the swamp and pass the third level."

With the last level passed, the water snake allowed Luo Chen and Qing Shuang to pick crystal fruits.

They picked the fruit carefully and felt the powerful power contained in it.

"You have proven your worth, and the crystal fruit will give you power," said the water snake.

Luo Chen and Qing Shuang bowed to the water snake in gratitude, then left the island with the crystal fruit.

They knew that this adventure not only allowed them to obtain precious fruits, but more importantly, they passed the test of mind, strength and wisdom and became more powerful beings.

"Opportunity is something that only those who are destined to have it will get it!"

Luo Chen couldn't help but sigh.

Luo Chen and Qing Shuang continued along the path with the crystal fruit.

Their hearts were filled with anticipation and excitement, but they also remained vigilant, for the mystery and danger of this swamp could not be ignored.

They passed through dense vegetation, crossed several streams, and finally came to an open space.

In the middle of the open space stands an ancient stone tablet, engraved with traces of time.

The stone tablet seemed to record an ancient legend about the swamp, but the words had long since become blurred and difficult to recognize.

Luo Chen walked forward and gently stroked the stone tablet with his hand, trying to feel the mystery within it.

Suddenly, he felt a slight vibration coming from the stone tablet, and then the scene around him began to change.

The grass and trees on the open space began to grow rapidly, as if time was speeding up. Luo Chen and Qing Shuang watched all this in amazement, and they realized that this might be a time barrier.

"Be careful, there may be unknown dangers hidden here." Qingshuang warned.

Luo Chen nodded, and they gripped their weapons tightly, ready to deal with any situation that might arise.

At this moment, the ground suddenly cracked, and a huge tentacle stretched out from the ground and headed straight towards Luo Chen.

Luo Chen dodged quickly, but more tentacles followed, and the entire open space seemed to have turned into a living monster.

"Another monster comes!" Qingshuang shouted loudly.

Luo Chen and Qingshuang fought side by side, using their agility and superb martial arts to deal with the tentacles.

Luo Chen's swordsmanship was as smooth as flowing water, and every swing accurately cut off the tentacles.

Qingshuang was like a nimble swallow, shuttling between the tentacles, and her weapon was like her shadow, following closely behind and delivering a fatal blow.

The battle lasted for a long time, Luo Chen and Qing Shuang both felt tired, but their will became stronger.

Finally, with a perfect coordination, they found the source of the tentacles, a huge underground creature.

Luo Chen used all his strength to stab the sword into its body, while Qing Shuang used her weapon to cut off its lifeline.

As the creatures died, the time barrier began to collapse, and the surrounding scene gradually returned to normal.

Luo Chen and Qing Shuang were breathing heavily, they knew that this victory was hard-won.

"Let's move on. There must be more secrets waiting for us to discover in this swamp." Luo Chen said.

Qingshuang nodded, and they calmed themselves down and continued along the path.

Soon they came to the entrance of a huge cave.

There was a cool breeze coming from the cave, as if some unknown creatures were hidden there.

Luo Chen and Qingshuang lit the torches and walked into the cave carefully.

The interior of the cave is spacious and deep, and the walls are covered with glowing minerals, illuminating the way forward.

They went deeper into the cave and found a huge underground lake. In the middle of the lake was a huge stone floating on which sat a white-haired old man.

The old man closed his eyes, as if meditating.

Luo Chen and Qing Shuang looked at each other. They knew that this old man was no ordinary person.

"Dear elder, we are travelers who accidentally broke in here. I wonder if you can guide us?" Luo Chen asked respectfully.

The old man slowly opened his eyes, and a deep light flashed in his eyes.

"You have passed the test of the swamp and come here. I am the guardian of this swamp. You can call me 'Zeling'."

Luo Chen and Qing Shuang bowed respectfully again. They knew that the old man in front of them possessed endless wisdom and power.

Ze Ling smiled and said: "Your hearts are pure, your strength is great, and your wisdom is extraordinary. The secrets of the swamp have been opened to you. Now I will give you the final gift."

Ze Ling stood up from the stone, and an ancient book appeared in his hand.

"This is the Secret Book of the Swamp. It records all the secrets and powers of this swamp. You can learn from it how to better use the power of nature."

Luo Chen and Qing Shuang took over the "Secret Book of the Swamp" and they felt a powerful force surging into their bodies.

They know that this is not just a book, but also a heritage and a responsibility.

“Thank you, Zeling.

Ze Ling nodded, his figure gradually became blurred and finally disappeared into the cave.

Luo Chen and Qing Shuang left the cave with the "Secret Book of the Swamp".

The swamp was explored here, and the opportunities therein were basically taken away by Luo Chen and Qingshuang.

Even so, there is still a small chance left.

It is estimated that it is not as good as the great opportunities they have obtained.

"I also discovered before that there is an empty city not far from here."

"Should we go take a look?"

Luo Chen and Qingshuang stood at the exit of the cave, looking at the city shrouded in fog in the distance.

They knew that although they had already gained most of the opportunities in the swamp, there might still be unknown opportunities and challenges hidden in the city.

"Let's go and take a look. There's nothing to do anyway." Luo Chen suggested.

Qingshuang nodded. She was always curious about unknown things.

The two packed their bags and headed towards the city.

As they got closer, the outline of the city became clearer and clearer.

This is an ancient city with walls made of huge stones covered with moss and vines.

The city gates were closed and it seemed that no one had entered or left for a long time.

But Luo Chen and Qing Shuang could feel that this city was not a dead city. It exuded an ancient and mysterious atmosphere.

They walked around the city wall and finally found a path covered by vines in a hidden corner.

Carefully pushing aside the vines, they found a half-open door.

Behind the door was a dark passage, at the end of which there seemed to be a faint light.

Luo Chen and Qingshuang looked at each other, nodded to each other, and then walked into the passage one after the other.

As they went deeper, the passage became wider and the walls were inlaid with glowing minerals, illuminating the way forward.

They came to a huge underground space, which seemed to be an abandoned market.

There were various stalls scattered around, with all kinds of strange items on them, some of which had already decayed, while others still exuded a faint luster.

Luo Chen and Qing Shuang walked carefully among the stalls. They knew that these items might hide unknown secrets.

Suddenly, Qingshuang's attention was attracted by a shabby wooden box on a stall.

She walked forward and gently opened the wooden box, inside which lay a crystal clear piece of crystal.

There seemed to be some kind of power contained in the crystal, which made Qingshuang feel inexplicably intimate.

"Luo Chen, look at this." Qingshuang called softly.

Luo Chen walked over and looked at the crystal carefully.

He felt a strong resonance, as if the crystal had some kind of fateful connection with him.

"This crystal contains powerful power, which may complement our power." Luo Chen said.

Qingshuang nodded. She knew that Luo Chen’s feelings were rarely wrong.

The two decided to take the crystal away, perhaps one day in the future, it would play an unexpected role.

Continuing to explore this underground market, Luo Chen and Qing Shuang discovered some ancient scrolls and strange potions.

They collected these items carefully, with awe of the unknown in their hearts.

Just then, they heard a slight sound of footsteps.

"There is someone?"

“Isn’t this an empty city?”

Luo Chen had such doubts in his heart.

The two quickly hid behind a stall and looked around vigilantly.

Soon, a figure walked out of the darkness. It was a mysterious man in a black robe.

The mysterious man didn't seem to notice the presence of Luo Chen and Qing Shuang. He walked straight to a corner, took out an item from a pile of debris, and then hurried away.

Luo Chen and Qingshuang looked at each other and decided to follow this mysterious man to see what he was looking for.

They followed the mysterious man carefully, passed through dark passages, and finally came to a huge underground hall.

In the center of the hall stands a huge stone platform inlaid with various exotic gems.

The mysterious man walked to the stone platform and placed the object in his hand into the groove of the stone platform.

In an instant, the entire hall was lit up with dazzling light, and the gems on the stone platform began to rotate, making pleasant musical sounds.

Luo Chen and Qing Shuang looked at this scene in surprise. They realized that this stone platform might be an ancient mechanism, and the mysterious man seemed to know how to activate it.

The mysterious man turned around and looked directly at where Luo Chen and Qing Shuang were hiding.

There was a hint of cunning in his eyes, as if he had already known of their existence.

"You guys are following pretty closely," the mysterious man said with a hint of teasing in his voice.

Luo Chen and Qingshuang walked out of their hiding place. They knew that the following conversation might reveal more secrets of this underground world.

"Who are you? What are you doing here?" Luo Chen asked. (End of this chapter)
