She stopped what she was doing and looked at Tian’er silently, but the doubt in her eyes was apparent.

"Most people can only rely on their own accumulation of Celestial Energy, then circulate the energy throughout their body one hundred and eighty times during the cultivation period. That method was extremely slow; at minimum, it would take at least five years. After entering the Xiantian realm, they could practice their cultivation techniques, and with the help of those techniques, they would be able to absorb Celestial Energy much faster. This was also why cultivation speed after entering the Xiantian realm is quicker than before."

"Couldn’t one practice their cultivation techniques in the Houtian Realm?" Mu Zhili immediately caught on to the key issue.

Tian'er nodded. "Most cultivation techniques cannot be acquired in the Houtian realm, but a very small number of great families or sects will have these cultivation techniques known as Mind Techniques! Their disciples start from the Houtian Realm and enter the innate realm with incredible speed. If you came across talents who are very strong at a young age in the future, it would only mean that the people behind them are very strong."
