After preparing the Shattering Realm Pill, Tang Feng began the alchemy process. In order not to be disturbed by Mu Qingwan and the others, he hung a "Do Not Disturb" sign outside the door, which had been agreed upon beforehand.
Previously, he would never dare to attempt crafting the Shattering Realm Pill, but now, being just one step away from reaching Gathering Spirit, he had the ability to do so, though his confidence in its success was not high.
After all, in his past life, he was only able to craft it at the Gathering Spirit Third Layer Heaven. Now, he could try using his experience, with three batches of materials providing just three opportunities.
After adjusting his mindset, Tang Feng began lighting the furnace. This time, he didn't rely solely on an open flame but combined it with Innate Yuan Qi to enhance the flame's temperature for more lasting and stable heat.
