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

Luo Chen took the book and read it carefully.

This book contains a lot of profound knowledge about refining equipment, some of which even he, an experienced equipment refiner, has never seen before.

"This is truly a priceless treasure." Luo Chen exclaimed, "With this knowledge, the magic tools we refine will have a qualitative leap."

Qingshuang also smiled excitedly, she knew what this knowledge meant to them.

The two continued to sort out their belongings, putting some precious instruments and materials into different categories.

During the sorting process, Luo Chen found an ancient parchment with some complex patterns and symbols drawn on it.

"Qingshuang, come and take a look at this." Luo Chen handed the parchment to Qingshuang.

Qingshuang took the parchment and studied it carefully.

After a while, she looked up, her eyes sparkling with excitement.

"Luo Chen, it seems that what is recorded here is a long-lost formation. If we can deploy it, our defense capability will be greatly enhanced."

After hearing this, Luo Chen was also very surprised.

He knew that if they could master this formation, their position in the world of immortal cultivation would be more secure.

"We have to find some time to study this parchment carefully." Luo Chen said.

Qingshuang nodded. She knew that this would take a lot of time, but it would be worth it in order to master this powerful formation.

In the next few days, Luo Chen and Qingshuang rested while studying the contents on the parchment.

They found that this formation was not only complicated, but also required special materials to set up.

"We need to collect these materials." Luo Chen said, pointing to a list of materials on the parchment.

Qingshuang looked at the list carefully and found that some of the materials were very rare and might take a lot of time to find.

"Let's start with materials that are easy to find," Qingshuang suggested.

Luo Chen agreed with Qingshuang's suggestion, and they began to ask around in the town, hoping to find the materials on the list.

After some effort, they finally collected most of the materials.

However, one of the materials, called "Tianxing Sand", has never been found.

"It seems we have to go to Tianxing Valley." Luo Chen said.

Tianxing Valley is a very remote place. It is said that there grows a special kind of sand and gravel, which is exactly the Tianxing sand they need.

"Tianxing Valley is far away from here, and the journey is dangerous. We must be fully prepared." Qingshuang reminded.

Luo Chen nodded. He knew that this journey would not be easy, but they had no way out.

In order to set up a powerful formation, they must go to Tianxing Valley.

After completing their preparations, Luo Chen and Qing Shuang set out on their journey to Tianxing Valley.

Along the way, they passed through dense forests and crossed steep mountains.

Although the journey was difficult, the two supported each other and faced various challenges together.

Luo Chen and Qing Shuang both understood that only by passing these tests could they become stronger.

"Luo Chen, have you ever thought about what to do if we can't find the Tianxing Sand in Tianxing Valley?" Qingshuang asked during a break.

Luo Chen pondered for a while, then replied: "If we really can't find it, then we can only think of another way. The road to immortality is not easy, and every step is full of challenges, but as long as we don't give up, there will always be a solution."

Qingshuang nodded, she knew Luo Chen was right.

They continued to move forward, with firm faith in their hearts.

After several days of trekking, they finally arrived at the entrance of Tianxing Valley.

Tianxing Valley is located on a desolate plateau, surrounded by endless mountains.

The valley is shrouded in clouds and mist, appearing mysterious.

"This is Tianxing Valley." Luo Chen said in a low voice as he looked at the scene in front of him.

Qingshuang also felt excited. She knew that what they were about to face would be a major test in their cultivation career.

The two entered Tianxing Valley carefully.

The scenery in the valley is strange, with strangely shaped rocks and gleaming sand and gravel everywhere.

According to the description on the parchment, they began to look for traces of Tianxing Sand.

"Luo Chen, look over there!" Qingshuang said, pointing to a piece of sand and gravel that was sparkling with silver light.

Luo Chen looked in the direction Qingshuang pointed, and saw that the sand and gravel were emitting dazzling light under the sunlight.

He was delighted, knowing that this was the star sand they were looking for.

"We found it!" Luo Chen said excitedly.

The two quickly collected some star sand and began to look for a way back.

However, just as they were about to leave, a sudden strong tremor came from the bottom of the valley.

"What happened?" Qingshuang asked nervously.

Luo Chen shook his head. He didn't know what happened.

The two walked cautiously towards the source of the vibration, wanting to find out what was going on.

They came to the bottom of the valley and found a huge stone gate with ancient runes engraved on it.

The stone door was slightly open, and it seemed as if something was trying to get out from inside.

"Be careful, Qingshuang." Luo Chen reminded.

Qingshuang nodded, she knew there were unknown dangers hidden here.

The two held their breath and slowly approached the stone gate.

Suddenly, the stone door opened completely, and a powerful force burst out from it, knocking Luo Chen and Qing Shuang away.

The two men fell heavily to the ground and felt dizzy.

"Luo Chen, are you okay?" Qingshuang struggled to get up and asked with concern.

Luo Chen shook his head. Although it was a little painful, it was not serious.

"I'm fine, Qingshuang." Luo Chen replied, and at the same time he stood up and brushed the dust off his body.

He looked at the stone door with a determined gaze, his heart full of curiosity and vigilance.

Qingshuang also stood up. She held Luo Chen's hand tightly, and the two walked towards the stone gate together.

As they approached, the runes on the stone gate seemed to respond to their arrival, emitting an even brighter light.

"There must be some secret hidden behind this stone door." Qingshuang said in a low voice.

Luo Chen nodded. He carefully observed the runes on the stone door, trying to decipher their meaning.

After a while, he slowly said: "These runes seem to be used to seal some kind of power. It seems we have to be careful."

They carefully passed through the stone door and found a huge cave inside.

In the center of the cave, there is a huge circular stone platform, on which is placed an ancient stone box.

The stone box was also engraved with runes, which echoed the runes on the stone door. "Could this stone box contain the source of the Heavenly Star Sand?" Qingshuang guessed.

Luo Chen did not answer. He walked forward and examined the stone box carefully.

He found that the lid of the stone box was not completely closed and seemed to be able to be opened.

He took a deep breath and slowly pushed open the lid of the stone box.

As the lid opened, a soft light emanated from the stone box, illuminating the entire cave.

In the light, tiny grains of sand and gravel slowly rose up and revolved around the stone box, as if they had life.

"This is the essence of Heavenly Star Sand!" Qingshuang exclaimed.

Luo Chen nodded, took out a special container from his arms, and carefully collected the sand and gravel.

These sands and gravels are purer than the star sand they found before and contain powerful energy.

"With these, our formation arrangement will be more perfect." Luo Chen said.

Qingshuang was also very excited. She knew what the essence of the Heavenly Star Sand meant to them.

They put away the container and prepared to leave the cave.

However, just as they turned around, the ground of the cave suddenly began to shake, and the stone box on the stone platform also trembled.

Luo Chen and Qing Shuang retreated quickly, looking around vigilantly.

"Be careful, Qingshuang." Luo Chen reminded again.

Suddenly, a dazzling light burst out from the stone box, illuminating the entire cave as if it were daytime.

In the light, a vague figure gradually emerged.

"This is." Qingshuang said in surprise.

The figure gradually became clear, and it turned out to be an old man wearing a simple robe and with a kind face.

The old man slowly opened his eyes, his gaze as sharp as a torch, sweeping over Luo Chen and Qing Shuang.

"Young men, why did you break in here?" The old man's voice was low and powerful.

Luo Chen and Qing Shuang looked at each other, then Luo Chen stepped forward and replied respectfully: "We are here to look for the Heavenly Star Sand, and we have no intention of offending you."

The old man nodded, his eyes softened: "Heavenly Star Sand is a treasure between heaven and earth, only those who are destined to have it can obtain it. The fact that you can find this place shows that you are destined to have it."

After hearing this, Qingshuang was delighted, because she knew that this meant they could take away the essence of the Heavenly Star Sand.

The old man continued, "But as you can see, the Sky Star Sand is not ownerless. I am the guardian of this place, responsible for guarding these treasures. If you want to take them away, you must pass my test."

Luo Chen and Qingshuang smiled at each other. They knew that this was a rare opportunity and also a test of their strength.

"Please teach me, Guardian." Luo Chen said firmly.

The old man smiled slightly, took out two items from his sleeves and handed them to Luo Chen and Qing Shuang respectively.

It was a pair of jade pendants with complex runes engraved on them.

"These are two jade pendants, each containing a different power. You need to cooperate and unlock the runes on the jade pendants in order to pass the test," the old man explained.

Luo Chen and Qing Shuang took the jade pendant and began to study it carefully.

They found that the runes on the jade pendant seemed to require the cooperation of two people to unlock them.

"Let's get started." Qingshuang said.

Luo Chen nodded, and they began to try to match the runes on the jade pendants one by one.

After some effort, they finally found the right combination.

As the last rune was put together, the jade pendant emitted a soft light, surrounding Luo Chen and Qingshuang.

After the light faded, they found themselves back at the entrance of Tianxing Valley.

"Congratulations, you've passed the test." The old man's voice sounded in their ears.

Luo Chen and Qing Shuang turned around and found that the old man had disappeared, only the pair of jade pendants lay quietly in their hands.

"We succeeded!" Qingshuang said excitedly.

Luo Chen smiled and nodded. He knew that this experience meant a lot to them.

Not only did they obtain the essence of Tianxing Sand, but they also passed the guardian's test and gained valuable experience.

"Let's go back, Qingshuang." Luo Chen said.

Qingshuang nodded, and the two of them, carrying the essence of Tianxing Sand and the jade pendant, walked towards the valley they had been to before.

This time, they had a great harvest.

Not only did they harvest a large amount of refining materials, but they also harvested a lot of the essence of the star sand used to set up the formation.

These things will be enough for them to use for a while.

Luo Chen and Qingshuang returned along the same path they came, feeling a sense of accomplishment.

They knew that this adventure not only allowed them to obtain precious materials, but also allowed them to take a step further on the path of cultivating immortals.

"Luo Chen, how do you think we should use the essence of these heavenly star sands?" Qingshuang asked curiously.

Luo Chen pondered for a moment, then replied: "These essences contain powerful energy. We can use them to improve the quality of magic tools, or to set up more advanced formations, but we need to study how to use them most effectively first."

Qingshuang nodded. She knew that Luo Chen had profound attainments in this area and believed that he could make the best decision.

After returning to the town, they did not leave in a hurry, but decided to stay in the inn for a few more days to better study the newly acquired materials and knowledge.

In the room of the inn, Luo Chen and Qing Shuang began to study the pair of jade pendants carefully.

The runes on the jade pendant are complex and mysterious, and seem to contain some powerful power.

"Luo Chen, look at this rune. It seems to be related to the formation we saw on the parchment before." Qingshuang said, pointing to a rune on the jade pendant.

Luo Chen took a closer look and found that the runes on the jade pendant were surprisingly similar to the formation on the parchment.

"This may mean that the runes on the jade pendant have some connection with the lost formation." Luo Chen said thoughtfully.

A glimmer of excitement flashed in Qingshuang's eyes: "So, can we perfect the formation by studying these runes?"

Luo Chen nodded: "This is a good idea. We can first try to understand the runes on the jade pendant, and then combine them with the formation on the parchment."

In the next few days, Luo Chen and Qingshuang hardly left the house. They devoted themselves to the study of the jade pendant and parchment.

They kept trying and kept failing, but every failure gave them a deeper understanding of these mysterious runes.

Finally, late one night, Luo Chen and Qing Shuang screamed at the same time.

"Qingshuang, I understand!" Luo Chen said excitedly.

Qing Shuang also nodded excitedly: "I found the key too!"

They discovered that the runes on the jade pendant were actually part of the formation on the parchment, and a key link.

By combining the runes on the jade pendant with the formation on the parchment, they can set up an unprecedentedly powerful formation.

"Once this formation is successfully deployed, our defense capability will be elevated to a new level." Luo Chen said excitedly. (End of this chapter)
