Traveling through time to cultivate immortality: a life and death test

Liu Xing closed his cave and began his arduous practice. After a year and nearly ten bottles of elixirs, he finally reached the False Elixir stage and felt the bottleneck of the Core Formation stage. However, taking elixirs no longer helped his mana, so Liu Xing stopped.

However, he still didn't rush into a breakthrough. He once again drew out his "Evil Inducing Technique." He had killed countless people in this war, and his body had accumulated even more evil energy than before. This evil energy must be refined, otherwise it would cause endless harm if it remained in his body.

So, he began practicing his technique, refining the evil spirit bit by bit. This process was extremely slow, taking him nearly three years. His cultivation had greatly improved, and the speed of refining the evil spirit was more than twice as fast as before. It was just that the evil spirit accumulated in him this time was so dense that it took so long to refine.

Afterward, he would channel this evil energy into tempering his body. But before that, he pulled out a jade box, which contained a white pill. Upon closer inspection, it was the Millennium Corpse King's Corpse Pill. Liu Xing had treasured this Corpse Pill for years, waiting for this very moment. The Corpse Pill, now a precious elixir for body-refining cultivators, had absorbed the corpse poison from Pangpang.

Liu Xing gently picked up the corpse pill between two fingers, examined it carefully for a moment, and then swallowed it in one gulp. Unlike other elixirs, the corpse pill did not melt upon entering the body, but instead penetrated into Liu Xing's dantian.

The corpse pill absorbed his spiritual energy, then emanated a miraculous power, nourishing his flesh and blood. He felt his physical strength slowly increasing through the nourishment of the corpse pill. Overjoyed, Liu Xing immediately began to practice the techniques from the "Evil Inducing Technique" to strengthen his body with evil spirits.

Under the combined force of the evil spirit and the corpse pill, Liu Xing felt as if his body was being torn apart, and pain ripped through him. He gritted his teeth and persevered, silently enduring this heart-wrenching pain.

It's no wonder there are so few cultivators cultivating the mind and body. This inhuman pain can truly torment someone to death. Even the world of immortal cultivation is fair; only those who endure the most difficult hardships can rise to prominence. Liu Xing has already grasped the benefits of possessing a stronger mind and body than a human: it provides a significant advantage in combat.

Therefore, as long as it can make him stronger, he will persevere no matter how much pain he endures, until his death. This is his determination.

This kind of pain was most unbearable in the initial stages of cultivation. As time went on, Liu Xing's nerves and body became numb, and the pain gradually subsided. After three years, the pain became almost imperceptible, and Liu Xing was able to endure it calmly, his expression unchanged and his heart steadfast.

Liu Xing's strength is the result of his silent dedication, which is many times greater than that of ordinary people, and the inhuman pain he endured. Only he knows this dedication. He doesn't need others to know, as he has a firm will, which is rare in the world.

On this day, Liu Xing was working hard on his physical training when suddenly, he felt a restless breath coming from the fat in his dantian.

He immediately released the cocoon formed by Pangpang from his dantian and placed it on the bed. Pangpang's aura fluctuated violently, and the surrounding spiritual energy frantically drifted towards him. A strong demonic aura rose to the sky. Meanwhile, above the Forbidden Peak, the wind and clouds moved strangely, forming a huge spiritual energy vortex. The experienced older cultivators instantly sensed it and guessed whose spiritual pet was breaking through to the fifth level.

"Which little demon broke through level five in my restricted area?" Su Xingchen slowly opened his eyes in the cave on the top of the mountain, and suddenly a powerful spiritual sense swept over.

"It turns out to be my disciple's natal golden silkworm Gu. This kid is blessed with great fortune and is already on the verge of a breakthrough. Now that his natal Gu has broken through first, it will also be beneficial for his next breakthrough." Su Xingchen muttered, then ignored it and continued to meditate with his eyes closed.

"Thunder tribulation?!" Su Xingchen had just closed his eyes, then suddenly opened them again, and stood up without warning, floating out of the cave.

The sky was clear, without any dark clouds or rumbling thunder. To outsiders, the weather appeared unchanged. Even Liu Xing himself couldn't sense any trace of thunder. However, Su Xingchen's cultivation was so powerful that he was so close that he could detect the presence of thunder even when dry thunder was emanating from dry land. Furthermore, because of the restrictions set by Su Xingchen himself in the restricted area, any movement within it could not be felt from outside.

"Master, please move aside, the thunder tribulation is coming." Pangpang's thought came.

"Ah, another thunder tribulation! What can I do for you?" Liu Xing was stunned. Although he had expected Pangpang to experience a thunder tribulation upon his advancement, as he had been struck by lightning at birth, his divine sense had scanned the sky and found no trace of lightning, so he thought he'd be spared this time. However, the rules of heaven dictated that any outlier in the cultivation world would be tested by a thunder tribulation, and no one could escape.

"No need for help, master. I can handle it." Pangpang said confidently.

Liu Xing finally felt relieved and quickly left the bedside. At the same time, he quickly took out a set of formations to reinforce the cave to prevent it from collapsing due to lightning.

Pang Pang's aura finally reached its peak, and Liu Xing sensed it as the aura of a Level 5 demon beast. The cocoon that had been encasing Pang Pang shattered, revealing the Golden Silkworm Gu's true form. It was still white and plump, but it seemed to have some strange tattoos on its body, faint and somewhat resembling skulls.

Pangpang curled up, exposing his relatively hard carapace, as if to resist the lightning strike. Liu Xing was extremely worried. He knew Pangpang was very weak and was worried that he would be shattered to pieces by the lightning.

"Boom!" Without warning, a bolt of green lightning suddenly appeared in the cave, landing on the bed and striking the Golden Silkworm Gu's body. Liu Xing's stone bed vanished as if vaporized, and a large hole appeared beneath it. Fortunately, Liu Xing had set up a defensive formation, otherwise the cave would have collapsed.

Liu Xing didn't bother worrying about the cave, instead using his spiritual sense to investigate the condition of Pangpang, who lay at the bottom. Pangpang was in a rather distressed state. Unlike the lightning tribulation he had easily endured at birth, this time, he seemed to be in much worse shape. He lay on the ground for two or three breaths before finally exhaling and regaining his composure.

"Master, I'm fine! I successfully advanced to level five! I'm so happy." Pangpang conveyed his joy through his thoughts.

Liu Xing immediately jumped to the bottom of the cave, scooped up Fatty in his palm, and examined him carefully. His aura was nearly three times stronger than before, and he indeed had a new skull pattern on his body, and he seemed stronger. Fatty twisted in his palm, expressing his joy, as if expressing gratitude to his master, or begging for praise.

Liu Xing was also overjoyed. Pangpang had become stronger, and he would be more confident in facing spiritual attacks in the future. Seeing that the Golden Silkworm Gu had successfully survived the thunder tribulation, Su Xingchen felt relieved and entered the cave to continue his meditation. He guessed that the Golden Silkworm Gu must have undergone some abnormal changes, which was why it had to undergo the thunder tribulation during its advancement. This also meant that the Golden Silkworm Gu was even stronger and could better protect Liu Xing, which was a good thing.
