The orthodoxy of Emperor Shangxi

In Haotian's immortal's cave in the divine temple.

Tang Hao sat in the hall, holding the pill cauldron and working hard on refining pills.

It had been three months since he came back from the divine Spirit Mountain. During this time, he had been making elixirs. After making the child divine pill, he would make the aperture opening pill.

The multi-child divine pill wasn't difficult. He could finish refining it quickly once he got the materials. The aperture opening pill, on the other hand, was slightly more difficult.

Even though he had continuously improved the refining method and shortened the time needed to refine a furnace, he still needed more than half a day to refine a furnace. At most, he could only refine two pills a day.

In three months, he'd made thousands of children divine pills, but he'd only made 140 aperture opening pills.

He had collected a total of 300 sets of ingredients from the alchemy Pavilion, but he had only refined half of them.
