The fourth Implant to be incorporated was of the Gold Attribute, because gold generates water.
The last one to be incorporated was the Earth Attribute Implant, because earth generates gold. (Note 1)
Hao Yi had suffered a severe injury when he attempted to construct his Martial Arts Foundation and aimed to Breakthrough, resulting in damage to his Tao Foundation, with the most severe damage being to the last incorporated Earth Attribute Implant "Magnetic Corner".
Since the last incorporated Implant plays the critical role of 'connecting the preceding with the following', once a Breakthrough attempt fails, the last incorporated Implant will bear the brunt of the damage, suffering the most severely!
Also, due to the absence of this link, Hao Yi's Fire Attribute Force could not circulate completely, and the fire toxin kept accumulating within his body, causing mutations in both his hands.
