I Have a Synthetic Mirror

In the thirteenth year of the Republic of China, China was in darkness.

[The panel is considerate of the host and proactively reduces material requirements] [Flat peach (×) → Flat peach core + Renshui × 2 → Xiantian Renshui flat peach (immortal product)] [If it is cooked once in three thousand years, the body will be healthy if it is eaten; if it is cooked once in six thousand years, it will live forever; if it is cooked once in nine thousand years, it will live as long as heaven and earth] ... [Tao-level materials detected! [The panel is making crazy deductions... The panel has decided to work overtime! [Jade Disc of Good Fortune (Remnant)×3→Hongmeng Purple Qi (???)] [The panel has burned itself, but it's worth it] [A ray of Hongmeng purple energy is the foundation of sanctification] [Host rushes!
