Chương 513: Chapter 40 Old Friend's Letter

Ten years later.

Chu Ning walked out of the Elixir Tower, and even though he had received the answers he sought, he continued to peruse the Jade Slips in the Imperial Library within the Elixir Tower for several years until the ten-year limit was up before coming out.

The opportunity to enter the Elixir Tower's Imperial Library and read the Jade Slips was a rare one.

If it had been other Nascent Soul Mid Stage cultivators, they might have been anxious to make a breakthrough in their realm, especially since their lifespans were nearing the latter stages.

But for Chu Ning, with no worries about lifespan, viewing more Jade Slips meant gaining more insight.

Knowledge is power, and sometimes knowledge can even save lives.

The variety of Jade Slips in the Imperial Library of the Elixir Tower was abundant, including introductions to forces from various domains and descriptions of the power of mighty techniques from some sects.
