He casually picked up the book and flipped through it.
The book was published in the Federation Calendar year 275, about five hundred years ago.
This book wasn't an ancient manuscript that had survived for five hundred years, but rather a photocopy of the original.
The first page of the book was the preface, an author's foreword.
The author was a biological professor at Dawn University.
He discovered a special "training" method from the First District within the fragmented ancient manuscripts left by the Original Federation, known as "Martial Arts."
This method had serious omissions, and at first, he thought it was as far-fetched as the old alchemical potions.
But during a chance experiment, he found that the "breathing techniques" described by this method could indeed enhance physical abilities to some extent, achieving effects such as improving health and extending life.
