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

Liu Xing returned to the Yulan Bay cave and carefully checked the restrictions placed outside the cave. Everything was normal and no one had touched it. Although there was nothing in his cave, the three restrictions he placed were always on and running. During the three months he was away, he wanted to test the security situation here and whether anyone had noticed him. He had just arrived in a strange city and didn't know much about the situation here, so he had to be cautious. He would rather spend more money and be more careful to ensure his personal safety. Seeing that everything was normal, he opened the restrictions and entered the cave. First, he let Jiao Jiao out of the pet bag. Jiao Jiao had been sleeping all the time.

"Master, where is this?" Jiao Jiao looked sleepy and rubbed his eyes with his paws, which was very cute.

"This is a human city. We have rented a temporary cave. I want to go into seclusion here to build my foundation." Liu Xing looked at Jiao Jiao lovingly and said gently.

"Master, are you finally going to build your foundation? That's great. I wish you success!" Jiao Jiao blessed happily.

"You can rest here while I'm in seclusion and see if you feel comfortable." Liu Xing took Jiao Jiao to the next room.

"Wow, the long one is just right for me." Jiao Jiao ran in and lay down comfortably. She didn't need to curl up, as it was more relaxing to lie down like this.

"Just rest here. I'm in seclusion next door. Don't run out. Humans and demons can't coexist. It's dangerous to go out." Liu Xing advised.

"Master, don't worry. I will stay here and not go out to protect you." Jiao Jiao said obediently.

Liu Xing nodded and retreated to his room. He hadn't slept in over a year. While meditation for a cultivator is rest, and long periods of sleeplessness are fine, sleep is still beneficial for health and enhancing one's energy and spirit. Now that he had obtained the Foundation Establishment Pill, he felt relieved. Furthermore, he was in a relatively safe environment in a human city. He suddenly felt tired and simply fell asleep in his room. Jiao Jiao, who was sitting next door, was surprised that his master was just as sleepy as him.

After three days and three nights of sleep, Liu Xing stretched himself, feeling refreshed and in better shape than ever before. He glanced over at Jiao Jiao, who was also dozing off, nodding her head in a adorable, silly way. Liu Xing smiled knowingly and ignored her, preparing to continue his meditation retreat.

A month later, he reviewed all he had learned, pushed his magic power to the point where it could not be improved any further, and then prepared to take medicine to build his foundation.

He took out a pile of spirit stones and placed them beside him. At the same time, he took out the two jade bottles containing the foundation-building pills, took out one, threw it into his mouth without even looking at it, and began to refine the pill.

The Foundation Establishment Pill entered his mouth, passed down his throat, and entered his stomach. Suddenly, a massive burst of medicinal power erupted. He immediately channeled this energy through his practice, practicing a full cycle. The spiritual energy contained in the pill was so immense that it stretched his meridians, causing them to ache. However, he could clearly feel the medicinal power nourishing his body and widening his meridians, complementing his special spiritual power. He channeled this immense medicinal power through his meridians over and over again. Three days passed, and apart from the feeling that his meridians had widened, his mana had improved, and his spiritual power had become denser, nothing else had happened. He hadn't even reached the bottleneck of the Foundation Establishment period, and the medicinal power of the Foundation Establishment Pill had already been depleted. It seemed that breaking through this bottleneck was indeed quite difficult; he had underestimated the difficulty. This showed that the hope of a cultivator with four spiritual roots successfully establishing their foundation was truly slim. Generally, reaching the ninth level of Qi Refining was considered the highest achievement of a lifetime. Without some special opportunity, establishing a foundation was impossible.

Liu Xing felt frustrated, but he had no other options. He pulled out another Foundation Establishment Pill and continued his meditation. The same overwhelming spiritual energy surged through his meridians, the same throbbing pain made him feel extremely uncomfortable. And still, he hadn't reached the bottleneck. But he gritted his teeth and persevered. If one pill didn't work, he would take two. This time, he had to break through the bottleneck in one fell swoop. Even if it meant exploding and dying, he would persevere to the end. If he didn't succeed, he would die.

Perhaps it was his determination to die, perhaps luck finally tipped his way, or perhaps it was the accumulation of sufficient medicinal power that finally, after taking the fifth Foundation Establishment Pill, he reached the threshold of his realm. By then, he could already feel his dantian and meridians becoming saturated, his body feeling extremely uncomfortable and as if it were about to burst. Liu Xing was now completely determined to achieve a breakthrough in one fell swoop. He took out two pills and swallowed them simultaneously, victory or failure hanging in the balance! Instantly, the double medicinal power took effect simultaneously, and an even greater surge of spiritual energy raged through him. Beads of sweat dripped from his head, his face flushed, and his body was on the verge of bursting. Jiao Jiao also sensed Liu Xing's abnormality and woke from her doze, standing up and nervously monitoring his condition.

"Master, come on, you'll definitely succeed," it prayed silently in its heart. But it couldn't help. Breaking through the realm could only be done on its own. Liu Xing had already made sufficient external preparations. So Jiao Jiao could do nothing but worry and pray.

Liu Xing channeled this spiritual energy with all his might, charging recklessly towards the diaphragm. This fearless aura, like a willingness to die, felt like a willingness to shatter into pieces. With a crack, like the sound of a porcelain bowl shattering, the bottleneck diaphragm finally broke. Liu Xing felt as if he had entered a new realm, his entire spirit and energy experiencing a breakthrough. He felt a surge of ecstasy. Had he finally broken through? He was still in a dream. For a moment, he frantically wanted to stand up and dance. This was a sign of impending obsession. If this continued, he would inevitably fall from a higher realm and possibly suffer serious injury. Terrified, he immediately focused his mind, maintaining a clear mind and calming the restless spiritual energy within him. A quarter of an hour later, after silently reciting the Heart Cleansing Mantra countless times, he finally returned to normal. Thinking about it now still brings a lingering fear.

At this moment, the spiritual energy within the Dantian began to slowly undergo a qualitative change. Originally, the spiritual energy was in a vaporous state, and the magical power was like an air current. Now, the spiritual energy has become liquid, and the magical power is more like a water flow. Originally, the Dantian was like a balloon filled with gas, but now it is like a pond filled with water. When the spiritual energy emerges from the Dantian, it is transformed into gas and flows into the body's eight extraordinary meridians. The spiritual energy absorbed from the outside, flowing through the meridians into the Dantian, is then transformed into liquid and stored. Therefore, after establishing the foundation, the spiritual energy stored in the Dantian is more than twice that of the original peak of Qi Refining, and the power of the spells cast is also more than doubled. Due to the recent breakthrough, the Dantian has also expanded, and the Dantian is not yet filled with spiritual energy. Therefore, he needs to meditate immediately and continue to practice to consolidate his cultivation.
