I was reborn as a young master in an invincible family of immortals

After his experience with the library, Lin Yun became even more resolute in his determination to improve his abilities as quickly as possible. Besides practicing breathing techniques in the courtyard, he also spent a significant amount of time studying the immortal cultivation texts he had found elsewhere in the family.

That day, Lin Yun was in his room, as usual, poring over an ancient book on the techniques of spiritual energy. The unique insights contained in the book struck him as a treasure, and he immersed himself in it, repeatedly pondering those obscure sentences, trying to integrate and apply them to his own needs.

"Brother Yun, you are studying hard again." Lin Wan'er's voice came from outside the door, and then she skipped into the house with an exquisite food box in her hand.

"Wan'er, why are you here?" Lin Yun raised his head and looked at his sister with a smile.

"I see you're busy practicing and reading all day, and I'm afraid you'll be tired, so I made some snacks for you. Come and try them." Lin Wan'er put the food box on the table, opened the lid, and a tempting aroma wafted into her nose.

Lin Yun felt a warm feeling in his heart. He picked up a piece of dessert and put it in his mouth. The sweet taste spread on his taste buds, making him feel a bit of the warmth of home after the intense training.

"Brother Yun, I heard that the family will hold a spiritual power test for the younger generation in a few days. You must prepare well." Lin Wan'er said as she watched Lin Yun eat snacks.

Lin Yun was slightly taken aback; he had actually forgotten about this. In the Lin family, such tests were held periodically. Firstly, they were used to understand the younger generation's progress in cultivation, and secondly, to select promising disciples for intensive training.

"Yes, I'll be ready," Lin Yun nodded, a glint of anticipation in his eyes. For him, this was not only a chance to test the results of his training, but also a chance to impress those who had looked down on him.

Over the next few days, Lin Yun intensified his training. He constantly experimented with the spiritual energy circulation techniques he had learned from ancient books. Although he encountered some minor issues with his spiritual energy going out of control, he was able to adjust in time.

Finally, the day of the family spiritual power test arrived.

The Lin family's martial arts arena was now filled with a large number of young men. Some were excitedly chatting, while others were nervously making final preparations. Lin Yun stood among the crowd, his expression calm, yet his gaze was resolute.

"Hmph, Lin Yun, I want to see what progress you can make this time. You almost went insane when you forced a breakthrough last time. Don't make a fool of yourself in this test again." A slightly sarcastic voice came from the side. Lin Yun turned around and saw that it was Murong Feng, who had always regarded him as a competitor.

Murong Feng was dressed in a gorgeous brocade robe and looked very dignified. He was surrounded by several young men from aristocratic families who were trying to please him. At this moment, they were all looking at Lin Yun with a playful look on their faces.

"Then don't bother with it, Brother Murong. Just take care of yourself." Lin Yun responded calmly, not being affected by Murong Feng's words.

Soon, several elders of the family appeared on the high platform in front of the martial arts field, and the spiritual power test officially began.

The younger generation of disciples stepped forward one by one in order and injected spiritual power into the test stone. The test stone would display corresponding light and level according to the strength and purity of the injected spiritual power.

Soon, it was the turn of the disciples ahead of Lin Yun. Some performed mediocrely, while others displayed considerable strength, drawing cheers from the crowd.

When Lin Yun stepped forward, the entire arena fell silent. Many people were waiting to see him make a fool of himself. After all, everyone still remembered his previous failed attempt at a breakthrough.

Lin Yun took a deep breath, slowly raised his hands, slowly gathered the spiritual power in his body, and then pushed it towards the test stone.

Instantly, the test stone erupted with a dazzling light, the intensity and purity of which far exceeded everyone's expectations. Those who had been expecting a joke stared with wide eyes, faces filled with astonishment.

Murong Feng's face instantly turned gloomy. He didn't expect Lin Yun to perform so well.

"Spiritual power level, upper mid-grade!" The elder in charge of the test announced loudly. His voice echoed in the martial arts field, causing an immediate sensation.

Lin Yun looked at the surprised expressions on everyone's faces, his lips curling up slightly. This was only the first step on his path to immortality. He wanted everyone to know that the once-looked-down Lin Yun had now shown his true potential. And in the future, he would go even further, until he solved the mystery of rebirth and stood at the pinnacle of this world of immortal cultivation.

However, Lin Yun's outstanding performance also brought him some trouble. Those from the side branches, who had originally envied his favor as a direct descendant, were now even more resentful. They secretly whispered and plotted ways to trip up Lin Yun and lower his status within the family.

After seeing Lin Yun's strength, Murong Feng's jealousy burned even more fiercely. He felt that Lin Yun's rise threatened his position among the children of the aristocratic families, so he decided to use all means to deal with Lin Yun.

Lin Yun was not completely unaware of this. He knew full well that the competition on the path to immortality was far more brutal than he could imagine. But he was not afraid. He believed that with the wisdom and tenacity of his past life, he would be able to overcome any challenge.

After returning to their residence, Lin Wan'er ran over excitedly, took Lin Yun's hand and said, "Brother Yun, you're amazing! Those who looked down on you before are now dumbfounded."

Lin Yun smiled and touched Lin Wan'er's head, saying, "Wan'er, this is just the beginning. There are more challenges waiting for me."

That night, Lin Yun sat at his desk. He didn't let his victory of the day get him complacent. Instead, he continued to browse through the immortal cultivation texts, pondering his next steps. He knew he still had a long way to go. Only by continuously improving his strength could he gain a firm foothold in this world of immortal cultivation, solve the mystery of rebirth, and achieve his goals.
