"Yes, but there's still a technical problem!" Han Jing Jing said,"the principle of this grade one and grade two automatic medicinal cauldron is to rely on a grade one Alchemist to control the temperature of the alchemy fire. In terms of the intensity of the fire, a grade one Alchemist's alchemy fire is definitely not as strong as a grade two Alchemist's alchemy fire. This part can be supplemented by external forces!" "What I'm thinking about is a material that can store and provide spiritual energy. As long as we can find this material, we can create grade one and grade two automatic cauldrons. However, it's quite difficult to find this material, and it's also a problem to charge it with energy! "Although we can earn a large sum of profit in the future by continuously helping grade one and grade two cauldrons charge their energy, even if we find this material, it's still difficult to charge it and how to charge it!"
