-_-. As for leveling up, the exp caps at about 70,000 after 15 minutes. So you can't leave your game on for a whole day in hopes of getting a million exp. xD Just let the MC smack these guys around for a good 20 minutes and he'll level up 2-3 times. It's guaranteed the best way to level up in the game.

Chord (geometry) A chord of a circle is a straight line segment whose endpoints both lie on the circle. A secant line, or just secant, is the infinite line extension of a chord. More generally, a chord is a line segment joining two points on any curve, for instance an ellipse. A chord that passes through a circle's center point is the circle's diameter. Every diameter is a chord, but not every chord is a diameter.
