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

"There must be something good in this box." Luo Chen said in a low voice.

Qingshuang nodded, and the two of them slowly approached the stone platform.

Just as they were about to touch the box, the cave suddenly shook, and the box on the stone platform trembled as well.

"Be careful!" Luo Chen shouted and pulled Qingshuang back quickly.

A strange purple smoke suddenly spread out.

And as the strange appearance spread, disgust spread.

Suddenly, more than a dozen practitioners wearing yellow robes and with their faces covered with yellow cloth appeared all around.

These practitioners seemed to have suddenly emerged from the cave wall. Their movements were in unison, as if they had undergone a long period of training.

Luo Chen and Qing Shuang looked at each other and saw vigilance and alertness in each other's eyes.

"Who are you? Why did you break into our forbidden area?" one of the practitioners asked in a hoarse voice.

Luo Chen took a step forward and replied in a deep voice: "We are just travelers who strayed into this place by mistake. We have no ill intentions. If this is really your forbidden place, we are willing to leave immediately."

"Leave? Not that easy!" Another practitioner sneered, "You have touched our holy objects, you must pay the price."

Luo Chen and Qing Shuang were shocked, they realized that this box might be a huge trouble for them.

But now that they have been drawn into this dispute, there is no room for them to retreat.

"We have no intention of offending you, but if you want to take action, we will not sit idly by and wait for death." Qingshuang gripped the hilt of the sword tightly, his tone firm.

The practitioners looked at each other, as if communicating something with their eyes.

Then, they attacked together, their movements were swift and strange, making them hard to predict.

Luo Chen and Qing Shuang immediately accepted the battle, they knew that this was a life-and-death battle.

Luo Chen's swordsmanship was sharp, Qingshuang's sword moves were agile, and the two cooperated well, and for a while they were evenly matched with each other.

The battle lasted for a long time and both sides suffered losses.

Although Luo Chen and Qing Shuang had good cultivation, they also felt tremendous pressure facing so many enemies.

Just when they were about to collapse, Luo Chen suddenly had an idea. He remembered the sword intent he had comprehended while practicing in the underground world.

He integrated this sword intent into his own sword skills, and suddenly the sword light became brighter and the power doubled.

Upon seeing this, Qingshuang immediately adjusted his sword moves to match Luo Chen's sword intent.

The two of them were like a pair of immortal sword lovers, with sword energy running rampant, forcing the practitioners to retreat step by step.

In the end, with the tacit cooperation of Luo Chen and Qing Shuang, they successfully repelled all the practitioners.

Seeing that the situation was not good, those practitioners retreated into the cave wall and disappeared without a trace.

Luo Chen and Qing Shuang breathed a sigh of relief. They knew that although the battle was won, the crisis was not completely resolved.

They quickly walked to the stone platform and took down the ancient box.

The box felt heavy in their hands, so Luo Chen and Qing Shuang did not dare to stay here for long and quickly left the cave.

They returned to the desert, found a relatively safe place, and began to study the box carefully.

The dust on the box was gently wiped away, revealing the complex runes on it.

These runes seemed to contain some powerful power, which made Luo Chen and Qingshuang feel a little nervous.

"The things in this box are probably very important." Luo Chen said in a low voice.

Qingshuang nodded. She knew that the box might contain a huge secret or unimaginable danger.

The two decided not to rush to open the box, but to find a safe place and carefully study the runes on the box to find the correct way to open it.

After some research, they discovered that the runes on the box bore similarities to the runes they had seen in the underworld.

This made them more convinced that the box had some connection with the underworld.

Luo Chen and Qing Shuang decided to return to the underground world, where there might be clues to unlock the secret of the box.

They passed through the light gate again and returned to the mysterious underground world.

In the underworld, they begin looking for clues similar to the runes on the box.

After a period of exploration, they finally found an ancient book in a hidden corner.

The book records a lot of knowledge about the underworld and runes, including how to interpret the runes on the box.

Luo Chen and Qing Shuang followed the instructions in the book and carefully unlocked the runes on the box.

When the last rune was unlocked, the box glowed softly.

Luo Chen and Qing Shuang held their breath and slowly opened the box.

In the box, a crystal clear fragment lay quietly.

Although, Luo Chen didn't know what this fragment was.

But he could vaguely feel that this piece of debris was definitely not an ordinary thing.

"Qingshuang, take a look."

Qingshuang carefully took the fragments out of the box. Her fingers gently touched the smooth surface. A strange energy wave emanated from the fragments, causing her body to tremble involuntarily.

"This... is this the legendary spirit crystal fragment?" There was a hint of disbelief in Qingshuang's voice.

Luo Chen frowned. Although he was not familiar with this fragment, he couldn't help but get excited when he heard Qingshuang say that.

Lingjing, a mysterious substance that is said to contain the purest energy in the world, is said to be able to help practitioners break through bottlenecks and even prolong their life.

"If it really is a spirit crystal fragment, then we are really lucky this time." Luo Chen took a deep breath and tried to calm himself.

Qingshuang nodded. She knew how precious the spirit crystal fragment was. She also knew that once this thing was spread out, it would attract countless greedy eyes and endless troubles.

She replaced the fragments in the box and carefully put the box into her storage bag.

"We have to find a safe place to study the use of this fragment." Qingshuang said.

Luo Chen looked around. They were now in the underground world. Although it was relatively hidden, it was not a long-term solution.

He pondered for a moment, then said, "Let's return to the ground and find a secret place to study the fragment carefully."

The two quickly left the underground world and returned to the ground.

They chose a deserted mountain far away from human habitation and found a hidden cave as a temporary resting place.

In the cave, Luo Chen and Qing Shuang began to study the fragments of the spirit crystal. They found that whenever they approached the fragments, the true qi in their bodies seemed to be attracted by something and became more active.

The energy contained in this fragment seemed to be able to resonate with their true qi.

"If we can utilize the energy in this fragment, our cultivation will surely advance by leaps and bounds." Luo Chen's eyes flashed with excitement.

Qingshuang seemed more cautious. She knew that although the power of the spirit crystal fragments was strong, it could bring disaster if used improperly.

"We must be careful. The power of this fragment is too mysterious and we know too little about it."

Luo Chen nodded, he understood Qingshuang’s concerns.

So, the two decided not to rush to use the fragments, but to find a safe way to absorb and utilize the energy in them.

In the following days, Luo Chen and Qing Shuang practiced while studying the spirit crystal fragments. They tried various methods to try to find a way to safely absorb the energy of the fragments.

After countless attempts and failures, they finally discovered a special practice method that could guide the energy in the fragments and integrate it into their true qi.

As their cultivation deepened, Luo Chen and Qing Shuang both felt that their cultivation was steadily improving.

The true Qi in their bodies became more powerful and even began to make a qualitative leap.

They knew that all this was due to the power of the spirit crystal fragments.

However, the good times did not last long.

Just as they were immersed in the joy of their improved cultivation, an ominous aura suddenly descended.

Outside the cave, a powerful force is approaching rapidly.

Luo Chen and Qing Shuang looked at each other and saw vigilance in each other's eyes.

They quickly collected the spirit crystal fragments and prepared to meet the upcoming challenge.

At the entrance of the cave, a figure slowly appeared.

He was a man in a black robe with an evil smile on his face and greed in his eyes.

"I want the spirit crystal fragments in your hands." The black-robed man's voice was low and threatening.

Luo Chen and Qing Shuang were shocked. They knew that the person who came had ill intentions and that the other party’s strength should not be underestimated.

But they also knew that the spirit crystal fragments were treasures they could not give up.

"If you want our spirit crystal fragments, it depends on whether you have the ability to do it." Luo Chen responded coldly, while tightening the sword in his hand.

Qingshuang was also ready for the battle, she knew that this battle would be a life-and-death battle.

The man in black robe didn't say anything else. He flashed and attacked Luo Chen and Qing Shuang like a ghost.

His attacks were swift and strange, making it hard to defend against.

Luo Chen and Qing Shuang immediately went into battle. They knew that this battle was a matter of life and death, and of the ownership of the spirit crystal fragments.

They exerted all their skills and techniques to the utmost and engaged in a fierce duel with the man in black robe.

The battle lasted for a long time. Although Luo Chen and Qing Shuang tried their best, the black-robed man was too powerful and they gradually felt overwhelmed.

Just when they were about to collapse, a mysterious sword intent suddenly appeared in Luo Chen's mind.

He integrated this sword intent into his own sword skills, and suddenly the sword light became brighter and the power doubled.

Upon seeing this, Qingshuang immediately adjusted his sword moves to match Luo Chen's sword intent.

The two of them were like immortal lovers in the sword world, with sword energy running wild and forcing the man in black to retreat step by step.

In the end, with the tacit cooperation of Luo Chen and Qing Shuang, they successfully repelled the man in black robe.

Seeing that the situation was not good, the man in black robe quickly retreated and disappeared into the night.

Luo Chen and Qing Shuang breathed a sigh of relief, the trouble was temporarily resolved.

They quickly packed up everything and left the cave with the spirit crystal fragments.

In the following days, Luo Chen and Qing Shuang continued to practice while avoiding possible pursuit.

They discovered that the spirit crystal fragments could not only improve their cultivation, but also help them comprehend more profound martial arts mysteries.

As time goes by, Luo Chen and Qing Shuang become stronger and stronger.

So, the two decided.

Return to the desert as before.

They wanted to go back and see what was so special about the desert.

Surprisingly, there could be such an opportunity buried there.

So, Luo Chen and Qing Shuang embarked on the journey back to the desert.

They knew that there were unknown secrets hidden there, which might be inextricably linked to the spirit crystal fragments.

Along the way, they remained vigilant at all times to avoid encountering enemies like the man in black robe again.

After several days of trekking, they finally arrived at the desert again.

The wind and sand are still there, but Luo Chen and Qing Shuang's moods are very different.

Deep in the desert, they discovered an ancient relic that was buried by sand, with only a corner exposed.

Luo Chen and Qing Shuang looked at each other and saw the excitement in each other's eyes.

They knew that there might be more secrets about the spirit crystal fragments hidden in these ruins.

They carefully cleared the sand at the entrance of the ruins, revealing a deep passage.

The passage was dark and damp, but Luo Chen and Qingshuang's perception abilities had improved greatly and they could clearly feel everything that was happening around them.

After going deeper into the ruins, they found a huge stone chamber with an ancient altar in the center.

On the altar, a pattern similar to the fragment in their hands caught their attention.

Luo Chen and Qingshuang walked forward and found that there was actually a complete spirit crystal on the altar.

"Is this a complete spirit crystal?" Qingshuang's voice was filled with shock.

Luo Chen nodded. He could feel that this spirit crystal contained even more powerful energy.

They carefully took the spirit crystal off the altar, and an even more violent energy wave instantly filled the entire stone chamber.

"We must handle this spirit crystal carefully. Its power far exceeds our fragments." Luo Chen reminded.

Qingshuang nodded in agreement. She knew that if they could make good use of this complete spirit crystal, their strength would have a qualitative leap.

But at the same time, they also have to face greater risks.

They decided to bring the spirit crystal back to the cave and continue researching how to safely absorb and utilize its power.

However, this time, Luo Chen didn't seem to be as lucky as before.

Hundreds of powerful people dressed in yellow, who seemed to be practitioners in the tribe in the desert, suddenly appeared behind them.

"Who are you?"

An old man with mysterious lines painted on his face walked over silently, leaning on a cane.

Luo Chen and Qing Shuang looked at each other and became secretly alert.

They knew that these yellow-robed practitioners were by no means ordinary people, and they obviously had a strong interest in spirit crystals.

"We are just practitioners passing by here. We have no intention of offending you." Luo Chen replied in a deep voice, trying his best to remain calm.

The old man's eyes were as sharp as torches as he swept across the spirit crystals in Luo Chen and Qing Shuang's hands, and a strange light flashed in his eyes.

"The spirit crystal in your hands is inextricably linked to our tribe. You must come with us."

Luo Chen and Qing Shuang felt nervous, as they knew this might be an unavoidable conflict.

However, they also understood that if they could cooperate with these yellow-robed practitioners, they might be able to uncover more secrets about the spirit crystal. (End of this chapter)
