The tao says that the maximum error in the time of the eastern emperor's bell has been reduced to about 50 years. The canoe is still there, and the tao thinks that it's a great beast. He ties it to a stake and says that he's going back to the sword-fighting sect first. He doesn't know where the current situation is in his hometown, but he knows someone there. He's waiting for his explanation about this. He says that according to the book of the bai xiuran, he should have been out of his life span a long time ago. It seems that the longevity pills he got from the scepter didn't last long enough. He adds 200 years to his old friend's life span, but that's not a good idea. He claims that he is a "practitioner" at the "foundation building stage" , which means that he knows how to build a foundation. He tells the old man that the true spirit accounts for only 1/10 of his cultivation base, and that about 90% of the cultivation base is filled with vital qi. The true spirit in the other 90% is less than 20. So, the value of the real spirit should be rounded down to zero. The old man says that if he adds 20 years, he'll be in the void stage between the golden core and the foundation stage. He also says that, since the void-foundation stage is between the qi-refinement stage and the core-building stage, he will have to explain himself before he leaves.
