How to Use: LVIII

  1. By manipulating the death of a human that has influence over another human’s life, that human’s original life span can sometimes be lengthened.

which means you can use the note to extend your lifespan in the example i gave:

have some one get the shinigami eyes by giving them your death note and have them write down your life span then give back owner ship of the death note to you again (use the note to manipulate them into doing so) for example lets say you die 1st arpril 2009 at 1pm

next find some one who will out live you, you could use the person who you manipulated into finding your life span we'll call this person mr.X

write down your own name and have the cause stabbed by mr.X after calling him fat at 1st april 2009 at 1pm

next write down mr.X's name in the death note and the cause of death is a heart attack just before stabbing some one on the streert who called him fat on 1st april 2009 at 12:58pm

now if this would work you should get his remaining life span. Would this work?

I believe you can extend someone's life by 23 days. If someone were going to die on April 1st, but someone wrote in the death note, "will die on April 23rd," that should extend the natural life span of the victim.

    -1 while this answer may be correct to other scenarios however in regards this question and what it detailed in the body this answer is incorrect. the question poses that Mr. X is killed before killing the death note owner which means Madara's second point comes into play

No, because of several things:

  • A human with the Shinigami Eyes cannot see the lifespan of other Death Note owners. (How to Use: XVIII)
  • If you write your name and a cause that cannot be possible (being stabbed by a dead man), you will die of a heart attack. (How to Use: LV)
  • Writing your own name in the death note bypasses all lifespan calculations. If you wrote that you die at a certain date, you will die at a certain date, regardless of how much lifespan you have remaining.
  • you could do the same as yagami did, when he gave up ownership so that his father could see his lifespan. Also can't you change the cause/time of death before the victim dies? @Madara Uchiha ♦

  • The third bullet point, isn't there a time limit of 24 days on the death? Sep 16, 2014 at 12:17
  • @Mindwin what kind of time limit? Sep 16, 2014 at 12:18

    XXVII: But the Death Note can only operate within 23 days (in the human calendar). This is called the 23 day rule. Sep 16, 2014 at 12:30

    but what has the 23 day rule to do with my question?
