After twenty days of relentless practice, Zhao Letian's alchemy skill had successfully reached the level of a second-grade alchemist, allowing him to refine Life Extension Pills as he wished.
During this process, he refined a large quantity of first-grade elixirs, many of which could enhance the cultivation of demon beasts. Leveraging these elixirs, he managed to boost the Fiery Flame Mantis's cultivation in one fell swoop to the ninth level of True Martial Realm.
Now, the power of the Fiery Flame Mantis had become extremely terrifying. Ordinary martial artists at the ninth level of True Martial Realm were simply no match for it. Even for Zhao Letian, defeating it proved to be a very difficult task.
Besides that, during the idle moments of alchemy, Zhao Letian also improved his array formation proficiency to that of a second-level Array Master. The arrays he set up now were so formidable that even powerhouses of the Sect Martial Realm found it challenging to break through.
