For Duan Ling Tian, it was extremely torturous to slow his speed and prolong the time of him heating the cauldron. It made him feel as though he was losing his mind. The feeling was similar to how if one possessed the fastest sports car but had to drive on an empty road at the speed of ten miles an hour for eleven hours straight. It was enough to drive an ordinary person insane.
Duan Ling Tian felt as though he had been given a new lease on life after he finally finished heating the cauldron eleven hours later.
'Since I've decided to do it, I'll definitely see it through!' Duan Ling Tian thought to himself as he exhaled. A light flashed briefly in his eyes. Then, he began to refine the pills while holding back his true skills.
