As the number one apothecary, Fu Jiangchen's skills in controlling flames and his grasp of medicinal properties were indeed top-notch. All Zhang Xuan had to do was verbalize the timing and the steps, and Fu Jiangchen would be able to pull them off with an amazing level of precision.
It did not take long for over a hundred medicinal herbs to be added into the cauldron, each of them perfectly fused with one another. All in all, they formed a sphere of medicinal fluid that was roughly the size of a fist.
At the start, Fu Jiangchen was still getting shocked each time he saw medicinal herbs that were usually hard to mix together fusing together perfectly, but there eventually came a point where he got numb to the shock.
It was starting to feel like as long as he followed Zhang Xuan's instructions, he would even be able to fuse even the heaven and earth impeccably together with one another.
