Just doing a rough calculation of the resources needed to bring his Divine Demon Body cultivation progress to 100% was enough to make Lin Xinghai's head spin.
Of course, high costs also meant high returns.
Although his Divine Demon Body cultivation had only reached 20% progress during this Marrow Tempering Realm stage, the strength of his arms had already reached two-thirds that of his legs.
By Lin Xinghai's estimation, as long as he completed the first stage of the Divine Demon Body cultivation, the strength of his arms would become equal to his legs.
And moving forward, his arms and legs would likely be strengthened together, which would explain the massive resource consumption.
After noticing this change, Lin Xinghai was no longer so conflicted. He spent another moment sensing the changes in his body before opening his eyes.
He then saw Zuo Wenyao looking him up and down nonstop.
