Chapter 169: 181. The Three Dantians

After a few minutes of talking about Koppi, the professor finally went to the subject that brought Mack to his house. "Well, you didn't come here to debate about Koppi with an old man, I will grab the meditation technique, just a moment,"  said the professor, standing up and walking to a bookshelf by the side. 

"This technique is not complete, is more like several parts glued together while trying to figure what was in the between" said the old man siting again, and looking at a piece of paper in his hands.

"You seem to still like to use paper...." said Mack, noticing that the meditation technique was not digitalized yet.

"Its easier to work for a man like me. This is an eternal work, so many trials and errors, there are several bits and pieces that still don't make sense, the parts in red are the parts that I tried to guess based on all that I found and the parts in green are the originals," said the professor passing the paper to Mack.
