Inside the stone gate, the space is larger than imagined, and there are thousands of medicinal herbs inside, each of which seems to have spirituality, and its surface is shining with a strange light. In the middle of the stone gate, there is a huge medicine pod.

For refining the Emperor Pill pill, Xiao Yan was very eager and curious, he carefully watched the prescription, and then counted the medicinal materials around him one by one, there were only three pairs of medicinal materials for refining the Wangu Dan, which meant that he only had three chances.

Taking a deep breath and nodding, Xiao Yan slowly calmed down and sat down in front of the medicine ding.

"Whew-" Xiao Yan slowly exhaled a breath, calmed his excited mind as quickly as possible, and slowly placed his slender hands on the fire mouth of the medicine ding.

"Poof!"

With a subtle sound, a wisp of pale yellow flame burst out from Xiao Yan's fingertips, and with a flick of his fingertips, the flames turned into a streamer of light, and rushed into the medicine pod like lightning.

The pale yellow trace of Chaos Shengyan had just entered the medicine tripod, and the tiny body suddenly expanded, and in just a moment, the tiny flames turned into raging flames, burning wildly in the medicine tripod, and with the pale yellow rising, the red medicine tripod on the surface looked even more mysterious and dazzling, looking like a bewitching fireworks.

"This medicine tripod on the Dou Emperor Continent is really not an ordinary thing, and the medicine tripod I obtained on the Dou Qi Continent cannot be compared to it at all." Looking at the medicine pod that still exuded crimson on the surface, Xiao Yan's eyes flashed with satisfaction.

After the temperature in the medicine pod reached a constant temperature, Xiao Yan made a move with his palm, and a medicinal herb exuding a little ancient aura was sucked into his hand, although the appearance of this medicinal material was not very good-looking, but the rich medicinal fragrance emanating from his body and the vicissitudes of life seemed to have experienced the vicissitudes of life, but it was obvious at a glance that this was not an ordinary thing.

According to the introduction of the prescription, this thing is called "Gu Ling Branch", it is in the deep mountains, after countless years, it is condensed by extremely pure energy, if the cultivator refines and absorbs it, it will make the fighting qi even stronger, even in the Doudi Continent, it is also very rare, and it is a very important medicinal material in the Ten Thousand Ancient Pills.

Holding the "ancient spirit branch" with two fingers, a sense of vicissitudes quickly penetrated with the fingertips, and the surrounding air seemed to be filled with ancient atmosphere.

With a slight throw, the ancient spirit branch was extremely accurately thrown into the medicine tripod, and the pale yellow flame surged violently, like a hideous mouth, directly devouring it in one bite.

In the face of the burning flames, the ancient spirit branch did not sit still, but continued to emit a stream of mist with an ancient aura to resist, trying to stop the erosion of the high temperature.

The mist and the pale yellow flames eroded at each other, and in the sneering sound, there was even a faint white mist at the junction. With the extremely strong energy that had been condensed for countless years, this ancient spirit branch was actually able to engage in a short-term stalemate with the Chaos Shengyan.

"Sure enough, it is a very rare medicinal material on the Doudi Continent......" Seeing this scene in the medicine tripod, Xiao Yan sighed in amazement, and then his heart moved, only to see that the temperature in the medicine tripod rose sharply!

Under the incineration of the Chaos Shengyan, which was getting hotter and hotter, the ancient spirit branch finally couldn't resist it, and the thing on the surface that was transformed by its own energy like a real thing began to show signs of melting.

Seeing this scene, Xiao Yan also breathed a sigh of relief, this is also thanks to the fact that he used the Heavenly Fire, if it is replaced by the previous different fire, I am afraid that it will take at least a day or two just to refine this ancient spirit branch, in that case, not only will it consume a lot of time, but also the consumption of Dou Qi will be extremely huge.

Heavenly Fire, for the alchemists of the Doudi Continent, is indeed no less than a divine weapon.

The refining lasted for about an hour, and the sturdy ancient spirit branch finally completely turned into a mass of ancient yellow liquid, and in the liquid flow, it exuded extremely rich pure energy. The refining was successful for the first time, which naturally included Xiao Yan's own extremely strong fire control ability.

After refining the ancient spirit branch, Xiao Yan spent another half an hour to complete the refining of it, and then without resting, with a movement of his palm, he once again put another medicinal herb that could also be called stubborn into the medicine tripod.
