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

"Qian'er, I don't blame you. You're testing the law for my own good." How could Liu Xing blame his wife, especially since he had already found a way to break the law.

So he told Nie Xiaoqian that he had also practiced the "Yin and Yang Harmony Technique".

"Husband, we have practiced such a technique, aren't we falling into the trap of the old demon Hehuan? If there is really a problem with the technique, won't we both be unable to break through to the Nascent Soul stage?" Xiaoqian said anxiously.

"Qian'er, don't panic. Your husband has only recently figured out that my main cultivation technique may also come from the upper realm, so I should be able to solve the problem of it not being able to form a baby." Liu Xing still chose to trust his wife and told her the special nature of his technique.

"So that's how it is. No wonder my husband is so powerful and can always challenge opponents of higher levels. Then I feel relieved." Nie Xiaoqian finally let go of her worries.

"Husband, your martial arts skills are so special that you can't let anyone know about them. I will use self-hypnosis to forget some of my memories about your martial arts skills to ensure that everything is foolproof." Nie Xiaoqian said gently to Liu Xing. Since her husband trusted her so much, she couldn't let him down.

"Qian'er, you are so nice." Liu Xing hugged his wife with pity.

"Disciple, you and your wife should come to my cave." Suddenly, Su Xingchen's old voice suddenly came into Liu Xing's cave.

Liu Xing and the other two sensed something was amiss, believing their master was nearing the end of his powers. Holding back tears, they hurried to their master's cave.

In Su Xingchen's cave, he saw his extremely old master, who was slumped on the bed, his back against the wall, his face full of wrinkles.

"Master!" Liu Xing called softly, rushed forward, held his master's body with both hands, let him lean gently in his arms, choked with sobs.

Upon touching his master's body, Liu Xing immediately sensed that his master was nearing the end of his life. Nie Xiaoqian also knelt beside him, weeping alongside him.

"My disciple, there is no need to be sad. Birth, aging, sickness and death are common to all human beings." Su Xingchen's old voice sounded. He looked up at his disciple and his wife beside him and felt very relieved.

"Master, please don't leave me, wuwu~" Liu Xing burst into tears, heartbroken. Thinking of the little care his master gave him every day, he felt even more heartbroken.

"My belongings are already in this storage bag and I'm handing them all over to you. I'm also handing over the Thousand Machine Sect to you. Just do your best to help. After I pass away, you must open all the restrictions in the cave when you leave, and let me pretend to be in seclusion, so that I can hide the truth for a hundred years. You and your wife must successfully conceive a baby within a hundred years to ensure the safety of the Thousand Machine Sect. If you can't conceive a baby within a hundred years, you must leave the Thousand Machine Sect immediately and wander the world. The Thousand Machine Sect has lost a great cultivator, and the ten major sects will not let our sect go."

After speaking such a long paragraph, Su Xingchen seemed to have used up all his strength and passed away.

"Master~" Liu Xing hissed softly, his throat seemed to be blocked and he was in extreme pain.

"My dear husband, please accept my condolences!" Nie Xiaoqian felt very sorry to see her husband so sad. She quickly crawled over, hugged her husband from behind and comforted him.

"Boom!" There was a sudden thunder in the sky and heavy rain began to fall, as if the heavens were weeping for Su Xingchen's death.

"Brother, rest in peace." Elder Cao Changyun of Bu Suan Peak suddenly opened his eyes, stood up, and looked towards the Forbidden Peak. He suppressed his inner grief and the urge to check, lest he alert the enemy. The Qianji Sect couldn't afford to be without a great cultivator, so he had to find a way to keep the secret for as long as possible. Finally, he bowed deeply towards his brother's cave as a farewell.

Liu Xing and his wife departed, bearing their master's belongings and hopes. Su Xingchen's remains rested peacefully in his cave. The passing of a generation of cultivation giants was a profound loss to the human world. Even if a cultivator's lifespan extended, they would eventually turn to dust like mortals if they failed to reach a new realm.

Returning to their cave, Liu Xing and his wife, turning their grief into motivation, continued their seclusion without pause, cultivating the Yin-Yang Harmony Technique together. During this time, the clone, as the sect leader and holding great power, also collected some precious elixirs and sent them to the cave.

Five years later, the two of them had mastered the secret technique to a small degree of success, and they finally reached the peak of the middle stage of the Core Formation Realm.

"Qian'er, it's time to break through." Liu Xing opened his eyes and said gently to his wife who was sitting cross-legged beside him.

"Well, my husband, I have been waiting for this moment for a long time. Qian'er has long wanted to truly become yours." Nie Xiaoqian said shyly and threw herself into Liu Xing's arms.

Perhaps it was the attraction of their dual cultivation techniques that caused them to lose all restraint and become a passionate passion. Liu Xing was already an expert in this field, and soon he had Nie Xiaoqian completely exhausted and unable to stop.

Liu Xing remained conscious and reminded his wife to practice the exercises. When they merged together, they used the power of yin and yang to break through the bottleneck.

Nie Xiaoqian had a high level of cultivation, and her Yuan Yin power was extremely strong. When it entered Liu Xing's body, it seemed as if he had obtained a tonic, and his whole body was full of strength. In an instant, his late bottleneck was torn apart, and a large amount of spiritual power from heaven and earth was injected into his body, strengthening his spiritual power and golden elixir.

Liu Xing seized the opportunity to refine the Yuan Yin energy that had entered his body, and then fed this Yuan Yin energy, which was imbued with spiritual power, back to Nie Xiaoqian. With this huge influx of spiritual power, Nie Xiaoqian successfully broke through the bottleneck.

The Yin-Yang Harmony Technique was truly mysterious. Their bodies merged, and spiritual energy formed a cycle between them. Liu Xing grasped the jade flute in one hand and began to transfer spiritual energy. In that instant, Nie Xiaoqian felt her spiritual energy drained away. She was startled, thinking something had happened to the technique. But it instantly returned, and the spiritual energy seemed much more concentrated than before, which reassured her.

She glanced at her husband and saw that he looked calm and seemed to have expected this, and she felt completely relieved.

In this way, Liu Xing and his wife successfully broke through to the late stage of Jindan by relying on the power of dual cultivation.

Another three years passed, and his cultivation in the late Jindan stage was completely stabilized.

Liu Xing sensed his wife's spiritual energy and discovered that the nourishment of his own aura had cleansed Nie Xiaoqian's bones and muscles, further enhancing her already exceptional talent and accelerating her cultivation. Not only had her physical condition improved, but the overall quality of her spiritual energy seemed to have also increased, her magical power becoming more concentrated. Unfortunately, his aura didn't remain within his wife's body. He forcibly intercepted some of it, but it eventually dissipated naturally within her. Reluctantly giving up, he concluded that it might be because the Jade Flute recognized its master and could only repay its owner.

While consolidating his realm, Liu Xing was also multitasking by using Gangfeng to refine his spirit, so at this time his magic power and spiritual awareness were both greatly improved. According to his estimation, he was not inferior to the average middle-stage Nascent Soul elder.
