Chapter 458: You're a Bloody Genius

Leonardo stripped all the twigs and leaves off the vine, wrapped both ends around his hands, and secured the center segment into the groove of the sawing board.

He took a deep breath and began to rub forcefully—

But right from the start, Leonardo realized it was far from as simple as he had imagined, for some reason the rubbing was jerky and uneven, without any feeling of smoothness.

At this rate, let alone starting a fire, it was very difficult even to accumulate a bit of heat.

"My goodness, this is completely different from what I thought." Leonardo increased the force in his hands, but the situation not only failed to improve, it became even more snagged.

Bi Fang reminded from the side, "Don't tense up completely, you need to pull the vine straight, the force should be applied longitudinally, don't apply too much pressure at once, the pressure should gradually increase as the heat builds up, imagine it as the blade of a saw, it's very strong and won't break."
