The first he needed was to fix up the stability of the horse carriage. Abel added 4 groups of bulky springs between the wheels and the body of the carriage as shock absorbers.
Abel was sure that the quality of these springs would be unmatchable. This was not only because Abel remembers how to make the spiral springs from his past incarnation, but it was also due to his incomparable strength.
When it came to making these springs, one needed to through the spring iron into the furnace. Then slowly strike it until it became a thick stick of iron. Afterward, one needed to wrap the stick of iron around an iron rod. Since Abel did not have the equipment for this, that's where his enormous strength could shine. Although these spring irons were not as strong as the 100 skills irons, it was still impossible for a normal human to bend. If Abel's body did not develop in such a rapid pace in these past few days, there's no way he could do this.
