After Thousands of Times of Hard Work, I Will Survive on My Own

Chen Yan, a craftsman who spent all his life forging swords in his previous life, opened his eyes and became a blacksmith apprentice who was seriously ill and dying. A book of quenching panels awakens: if you temper it with your own hands, the heat will rise - but the heat will rise more than it will damage, and it will not be quenched if there is no damage. If you want to refine your body into a sharp weapon, you must first feed the furnace with your own flesh and blood. Tempering the skin, forging the tendons, casting the bones, refining the blood... Nine refinements lead to a sharp edge. While others practice Kung Fu to become stronger, he practices Kung Fu by first injuring himself and then knocking him back with hammer after hammer. Someone asked Chen Yan: Is it worth it? He said: If the fire is not extinguished, the iron will not be cold. This is a story that puts a price tag on "coolness" - strength is not determined by one's origin, and one should make it on his own.
