Chapter 415: Dan Lei Rolls
Xiao Yan looked through the ice mirror at the herbs being refined in the medicine cauldron. Although the power of the Yin-Yang Dual Flame was close to the top five on the Strange Fire List, there were too many herbs that needed to be refined this time and it would take longer.

At this time, many stone platforms were suspended in the sky, and every participating alchemist was conscientiously refining medicinal materials. For a moment, the entire square became extremely quiet, with only the burning flames and the crisp sounds of the medicinal materials being refined.

Alchemy is an extremely boring task, especially refining these high-level elixirs, it is normal to spend ten days to half a month.

Almost none of the pills refined at this alchemy conference were lower than the seventh grade. After all, pills lower than the seventh grade could not win in the alchemy conference.

It would take at least ten days to refine a seventh-grade elixir, so after five or six days, the square was still very quiet.

Time passed little by little, until the seventh day, when a sound like muffled thunder was heard in the square. This sound was very familiar to alchemists. Whenever they heard this sound, it meant that the medicine refining had failed.

But it’s okay to fail, you just need to prepare the herbs again and continue refining. There is no rule at the alchemy conference that stipulates how many times you will be eliminated based on failure, but if someone fails three times in a row, they will leave on their own initiative. This is an imperceptible rule.

"boom!"

The originally blue sky was suddenly covered by dark clouds, and a low, muffled thunder rang in everyone's ears.

Countless eyes subconsciously looked up at the sky, only to see a dark cloud appeared in the sky at some point, with lightning appearing in the cloud.

"Dan Lei!"

Most of the people present were alchemists, and almost none of them were unfamiliar with Dan Lei. The appearance of Dan Lei meant that the elixir was about to be successfully refined, and it was a seventh-grade elixir. After all, sixth-grade elixirs rarely attracted Dan Lei.

At this time, countless people turned their eyes to a stone platform under the dark clouds and found that there was a middle-aged man there looking at the thunderclouds in the sky with a smug look on his face. After all, he was the first person to attract Dan Lei.

With the appearance of the first Dan Lei, a chain reaction seemed to have occurred in the field. A Dan Lei appeared every half a day. However, the Dan Lei were relatively weak. Most of them were single-colored, and only a few were two-colored.

As time passed, the frequency of Dan Lei appearing in the field became lower and lower, and finally there was no Dan Lei appearing for several days in a row.

At this time, there were still more than a dozen people refining pills on the stone platform. Such a long time had passed, but they had not yet succeeded in refining the pills. Obviously, the pills they refined were more advanced and were eighth-grade pills.

Although the eighth-grade elixir and the seventh-grade elixir are only one level apart, their efficacy is vastly different, and the time required to make them is also incomparable.

The biggest difference is that the eighth-grade elixir has spirituality, which is why one must reach the spiritual realm in order to refine the eighth-grade elixir.

Because only when the soul level reaches the spiritual realm can spirituality be added to medicinal materials and elixirs when refining medicine. Elixirs without spirituality are just dead things, while elixirs with spirituality are considered to be endowed with life and can survive forever.

"boom!"

A thunder roared far louder than the previous one, and the whole square was shrouded in dark clouds. Such a terrifying sound could only be produced when an eighth-grade elixir was formed.

At this time, a pale figure sat cross-legged on the stone platform, looking at the huge dark cloud above his head, and immediately breathed a sigh of relief, and then continued to warm the pill that had already formed. As the pill continued to be warmed, the thundercloud rolled rapidly, and the three colors of green, silver and red appeared, rendering the pill thunder into a three-color state.

Dan Chen looked at the three-colored Dan Lei in the sky and sighed. Although she wanted more Dan Lei, her body and energy had reached their limits at this moment. She couldn't go on at all and had to give up.

"Three-colored Dan Lei?" Cao Ying looked at Dan Chen not far away. She had always regarded Dan Chen as her opponent before, but since Xiao Yan appeared, she had focused her attention on Xiao Yan. At this time, she just wanted to see the results of dealing with the previous opponent.

Cao Ying looked up at the sky, and then his hand seal changed. A bright beam of light shot out from the medicine cauldron and shot straight into the sky.

At the end of the light column, energy surged wildly. As the energy surged, thick fog began to gather rapidly and eventually took the shape of a thundercloud.

"Your disciple is not bad! This Dan Lei is probably also three-colored Dan Lei." Yao Chen looked at the thunderclouds that were rapidly forming in the sky, then glanced at Xuan Kongzi beside him and couldn't help but smile.

Hearing this, Xuan Kongzi's mouth twitched suddenly. As Cao Ying's teacher, he naturally knew how capable Cao Ying was. Before meeting Xiao Yan, Cao Ying's best result was only two colors of Dan Lei.

But ever since he was defeated by Xiao Yan in the last assessment of the five major families, he has suppressed his arrogance and focused on improving his alchemy skills.

Of course, it was not only Cao Ying who was hit hard, but also Dan Chen from the Dan family, otherwise he would not have achieved the current good results.

During the communication between Xuan Kongzi and Yao Chen, the Dan Lei on Cao Ying's head soon showed three colors.

Cao Ying looked at the three-colored thunder in the sky with a look of satisfaction on her face. After all, this was the best result so far.

"Three-colored Dan Lei?" Old man Mu Gu was a little shocked when he saw Dan Chen and Cao Ying created the three-colored Dan Lei, but he didn't take it to heart.

Old Man Mu Gu shifted his gaze away from Cao Ying and immediately looked towards the stone platform where Xiao Yan was. He didn't care about anyone else and only regarded Xiao Yan as his real opponent.

Xiao Yan felt a pair of cold eyes staring at him, and then a sneer appeared on the corner of his mouth. He knew who it was without even looking.

Old Man Mu Gu used his soul to detect the elixirs made by Xiao Yan. Because Xiao Yan did not hide them deliberately, most of them could be seen to be the elixirs made by Xiao Yan.

"Poria Green Pill?" Old Man Mu Gu found out that what Xiao Yan refined was only an eighth-grade intermediate pill. Although this kind of pill was good, it was still a little bit worse than his. It was estimated that the pill Xiao Yan refined could only attract three-colored pill thunder like Cao Ying and Dan Chen at most.

Of course, according to the investigation of old man Mu Gu, there was also a powerful old man in green. The elixir refined by this old man in green was also of eighth grade, but this old man obviously did not want people to know what kind of elixir he refined, so he hid it with his soul power.

However, this could only be hidden for a short time. A beam of light shot out from the green-clothed old man's medicine cauldron, and immediately a huge dark cloud condensed in the sky. The thundercloud rolled, and soon formed a three-colored pill thunder.

"It seems that the final champion of this alchemy competition will be me." Old man Mu Gu curled up a smile and then turned his gaze to Xiao Yan again. At this time, only he and Xiao Yan had not yet completed the alchemy, so the victory would only be between the two of them.
