Life After Prison by Silencieux novel Chapter 2949

With the Small Thousand Worlds thriving perfectly fine, Severin did not see any reason to expand it for the time being.

Ever since becoming a true immortal, he harbored a desire to extend the Small Thousand Worlds, yet conventional methods proved to be inadequate for the job. Only by continuously comprehending the laws of the three thousand rules and the consolidation of the realm's origins could allow the expansion to occur organically. Such an aspect mirrored closely the practices of true immortals in the real world—they too required an understanding of those laws.

Severin remained relatively unconcerned over that. With the assistance of the Small Thousand Worlds, he had already manifested the rules and established many of them to small success, while others had fully developed to great success. He understood that progress would naturally follow as long as he continued to channel the power of heaven and earth within himself.

Thanks to distinct training systems, Severin circumvented the initial bottleneck that frequently became an obstacle in the progress of other true immortals. According to information from the Green Emperor's remnant soul, the attainment system of ancient times was markedly different from the modern era.

Back then, the celestial realm operated solely under the rules of heaven and earth, boasting a total of 129,600 paths. Ordinary practitioners could easily grasp those rules and attain immortality upon reaching level nine supreme paragon as long as they dipped their hands into the river of time and acquired the rules.

However, the rule of heaven and earth was later taken away and only the person who had it could use it to train. Newcomers, in spite of their remarkable talents, were no longer able to achieve immortality via that route.
