Cautious until I reign supreme

Xu Tianran was an ancient powerhouse in the immortal world, standing at the peak of the Golden Immortal realm. Having lived for 100 million years, he had reached the end of his lifespan. Yet, despite all his efforts, he had been unable to break through to the Heaven Immortal realm.

The path forward required merging comprehended laws to form a concept, but even the slightest flaw in the merged concept would cause the immortal to be devoured by the very laws they sought to control. Xu Tianran's talent was simply not enough to take that risk. Instead, he chose another route—dedicating the last five million years of his life to perfecting his Supreme Laws to 100 percent mastery for a grand plan that would defy fate itself.

Unlike others who relied on divine blessings or mystical systems, Xu Tianran had no system guiding him. He was a transmigrator from Earth, and through sheer hard work, countless battles, and endless sacrifices, he had clawed his way to the peak. But now, at the brink of death, he sought true immortality—eternity itself.

A simple reincarnation would not suffice. Reincarnation was random, and with it came the risk of being born without talent, rendering all his efforts meaningless. He needed absolute control over his next life.

As the end drew near, he activated his plan. With unwavering determination, he circulated the power of his mastered Supreme Laws—Space, Time, Karma, and Reincarnation—within his soul. This was a suicidal move, as even merging two ordinary laws had been impossible for him before. The Supreme Laws would surely devour him. But that was precisely his intent.

For millions of years, he had scoured countless secret realms, obtaining Supreme Law Origin Stones that had allowed him to cultivate these laws to their peak. Now, with his will, Golden Immortal origin energy, and soul spiritual energy, he merged everything into a chaotic, devouring force—and threw himself into reincarnation.

Darkness consumed him.

When he next opened his eyes, he felt a strange sense of nostalgia. He saw small hands and tiny legs, his body weak and unfamiliar. The cold air of a hospital surrounded him.

He had done it.

He had returned to Earth.

Xu Tianran was born on Earth—his first plan had succeeded. However, this was only the beginning. For his next step, he needed to comprehend the Law of Technology and use it to create a system that would aid in the final stage of his grand plan.

Though he was now a mortal, with no cultivation or soul energy left, his will and memories remained intact. Still, his newborn body could not handle complex thoughts for long, and as his infant consciousness struggled, he eventually succumbed to sleep.

He grew up as an orphan, displaying extraordinary intelligence from a young age. Eventually, a wealthy family adopted him, but he cared for nothing except his goal. To prepare, he devoted himself to studying computer science, space science, and fundamental laws of Earth.

With Earth's thin spiritual energy, cultivation was nearly impossible. Still, he used medicinal ginseng to reach the 9th level of the Body Tempering Realm, but that was his limit. Unable to progress further through cultivation, he turned his focus entirely to science and technology.

By the age of 20, he had invented an advanced artificial intelligence, earning a Nobel Prize—an achievement that meant nothing to him. His true goal was funding. By leveraging his AI, he revolutionized medicine, advanced technology, space exploration, and computational processes. With this, his comprehension of the Law of Technology reached 100%, aided by his past mastery of Supreme Laws.

But his plan required enormous energy, and the Earth's limited resources were insufficient. Destroying the Sun was out of the question—it would mean Earth's destruction. Instead, he constructed a spacecraft capable of traveling to the nearest star, preparing advanced heat and radiation resistance technology based on his understanding of the Law of Technology.

As a mortal, he could not absorb a star's energy directly, nor could he simply reincarnate. To implement the system into his soul for his next reincarnation, he required an unimaginable amount of energy. With precision and patience, he built the necessary materials and machinery to harvest a star's energy. This mission was another suicidal gamble, but he had no choice.

After 25 years, he reached the nearest star and activated his plan, absorbing just enough of its power without destroying it. Then, he took the final step.

Channeling the supreme laws of Time, Space, Reincarnation, and Karma, along with the Law of Technology, he began the process of merging them into his soul to create the system. This would allow him to reincarnate into a high world beneath the Immortal World, where the upper cultivation limit was the Tribulation Transcendence Realm—a realm where cultivators first began to comprehend laws. This choice was made for safety and effective cultivation, as reincarnating into the Immortal World carried a 10% risk of powerful cultivators detecting an anomaly in the laws.

As the energy reacted to his will, he experienced soul-tearing pain, his very existence beginning to fade into nothingness.

Then—his soul transmigrated.

Within the Heaven Sword Sect, the cry of a newborn child shook the entire sect.

Xu Tianran was born again.
