Opinion polls show that it took two thousand years for Lao Wu's seeds to mature, and hundreds of years for Mianchuan Xufu's seeds to mature. How did the seeds of pepper mature for more than twenty years? According to different records in Civil Affairs Records and Mianzhuan, it takes a long time for the seeds of Lao Wu and Xu Fu to mature, because their seeds are specially ripened. The seeds of pepper have matured for more than 20 years, probably because pepper is different from Lao Wu and Xu Fu in some aspects.

The use of ripening agent can accelerate the growth and maturity of plants. Although the seeds of pepper look like naturally matured seeds, in fact, their ripening speed has been accelerated. This ripening method can be widely used in the process of pepper planting to make pepper seeds mature in a short time.

In addition, peppers may have different growing environments and conditions. These factors may affect the growth and maturity of pepper, so that the seeds of pepper mature in a short time.

It should be noted that these are just some possible explanations. In fact, different authors may have different understandings and descriptions of the use of ripening agents, growth environment and other factors, resulting in different characters in different works having different seed ripening times.
