After returning to the cave abode, Tang Hao started writing the teaching materials.
In this aspect, he was very experienced. In the past, he had compiled books on many kinds of medicine. Now that it was alchemy, he was familiar with it.
He took out all the alchemy books he had on him and read through them carefully. Then, he wrote down all his experiences and insights in alchemy over the years and compiled them into teaching materials.
This was a massive project. Tang Hao had collected countless alchemy books over the years. There were at least a million of them. Reading through all of them once would consume a lot of time.
Moreover, he still had to tidy up.
Fortunately, he had a lot of split souls, and if he didn't have enough, he could just cut off another batch. In his mobile immortal's cave, thousands of split souls were put into this project.
They held stacks of books and baskets of Jade scrolls and flipped through them.
