Chapter 345: ‘Yuan-Xu Dan’? Easily controlled

Xu Feng picked up the jade slip in front of him, and then probed into it with his spiritual sense.

He found that the recipe recorded a kind of elixir called Xuyuan Dan. The effect of Xuyuan Dan can make the person who takes it accumulate more mana in the dantian in a short period of time.

Although this elixir is only ranked as the second-grade lower grade, there are many second-grade middle-grade spiritual medicines among the medicinal materials listed in the recipe. The difficulty is relatively high, and it is still very suitable to be used as a test topic.

Looking around, he found that everyone was studying the elixir recipe. Master Lan kept a straight face and continued to explain:

"For this competition, the sect specially gathered the fourth-grade alchemists together and developed a hundred new second-grade and third-grade elixir recipes. The 'Xuyuan Dan' in your hands is one of them.

The situation of other groups is the same as yours. They will draw other second-grade lower-grade elixir recipes to compete. If the research is almost the same, you can start refining."

After speaking, Master Lan flew to a three-meter stone platform in front of everyone, sat cross-legged, and closed his eyes to meditate.

Xu Feng, who had just finished studying the pill formula, happened to see this scene. He thought to himself that although it seemed that this senior seemed to be in a trance, he dared to guarantee that all the contestants in the entire hall must be under his close surveillance, and any disturbance would not escape his control.

Holding the pill formula in his hand, he glanced around and found that everyone's expression was different.

Those second-level low-grade alchemists had sad faces and were not very confident. Just now they thought that the rules of the competition were in their favor, but now it seems that it is not entirely true.

The second-level middle-grade alchemists had no joy or sadness on their faces. This new second-level low-grade pill was a big challenge for them, and they looked eager to try.

As for the second-level high-grade alchemists, some have already started to select medicinal materials and preheat the pill furnace. For them, although the competition topic has changed, due to their high level of alchemy, a mere second-level low-grade pill is not a big problem for them.

His eyes fell on the medicine shelf, where ten portions of spiritual medicine materials needed to refine the Yuan-saving Pill were neatly stacked.

Next to the spiritual medicine, there was a jade bottle made of mutton-fat jade, which was probably used to store the pill.

After scanning the things on the medicine shelf, Xu Feng calmed down and looked more relaxed.

With his current level of alchemy, ten portions of raw materials were enough to refine a furnace of second-level medium-grade pills that had never been refined before, not to mention second-level low-grade pills. About three portions were enough.

However, he did not become arrogant because of this. There were too many things that happened in the gutter, so he had to be vigilant at all times.

After the preparations were done, Xu Feng used his magic power to strike, and the stone slab at the bottom of the pill furnace used to cover the ground fire was easily removed by him. A flame burst out from the ground and began to preheat the pill furnace.

When the temperature of the entire pill furnace rose higher and higher and reached a certain critical point, he used his magic power to lift the lid of the furnace, picked up a Tongxin flower and threw it into the pill furnace.

When Xu Feng was refining the elixir, he was focused and attentive, so he didn't notice that when everyone entered the alchemy mode, the area where each of them was located was separated by a light curtain that suddenly rose from the ground.

This was done to ensure that the participating monks were not disturbed by external factors. Even if an unlucky person caused the furnace to explode due to improper control of the fire, it would not affect other contestants.

"Shh!"

With a muffled sound and bursts of black smoke, Xu Feng's first attempt at refining the elixir ended in failure.

"The senior fourth-level alchemist who created this elixir recipe had a sinister intention. He actually put the spiritual medicines with completely opposite properties into the furnace in order, which easily caused the fire to switch in time and finally led to failure.

However, this arrangement can truly test the level of the alchemist, which is quite interesting."

Xu Feng silently summarized the reasons for the failure just now, then raised his head and looked around, and found that among the five second-level top-grade alchemists, three of them failed in the first attempt like him.

The remaining two were relatively smooth, and both had reached the final stage of pill condensation. Seeing this, Xu Feng secretly encouraged himself and then started the second attempt.

"No, after all, it is a pill formula developed by a fourth-level alchemist specifically for the competition. In addition to setting up difficulties in the order of the release of spiritual medicines, it also set up obstacles when condensing the pill. Without a sophisticated pill collection method, it is simply as difficult as ascending to heaven to condense the pill in the end."

This time, Xu Feng successfully passed the stage of releasing spiritual medicines and refining essences, but in the final stage of pill condensation, he encountered new difficulties and finally failed, and only got a large mass of black medicine residue.

However, Xu Feng was not discouraged. The master was not worshipped in vain. After Lu Zhenren accepted him, he once taught him a set of sophisticated pill condensation methods, which were extremely complicated.

It's just that when he usually refines pills, the general pill condensation method is enough, so the complicated method is rarely used because it is too time-consuming.

But this does not mean that he has not mastered this set of pill-condensing techniques. In fact, he has already mastered it, but he does not use it often. Today, he finally put it to good use.

After sorting out his thoughts, he began his third attempt at refining pills, and he was still calm and composed.

After failing just now, he observed the situation of other contestants and found that except for a second-level top-grade alchemist who successfully refined the "Yuan Dan", all others were stuck at the step of condensing pills.

Therefore, he was not in a hurry, not at all!

He scanned the required medicinal materials one by one, and then threw them into the medicine cauldron in an orderly manner. Under the induction of his spiritual consciousness, each spiritual medicine was wrapped in the right amount of earth fire heat, and then various medicinal essences were extracted.

Under his steady control, in the cauldron, the spiritual essences required for the "Yuan-Xuan Pill" were arranged in order, gradually merging, and the prototype of the pill gradually emerged.

"Condensate!"

With a loud shout, his ten fingers quickly interacted, and various seals changed endlessly, so fast that only a series of residual images could be seen.

After a few breaths, a gust of strong wind accurately fell on the top cover of the cauldron. Xu Feng casually copied a jade bottle, took off the bottle cap, and lined up a row of pills flying towards him, and flew accurately into the pill bottle.

"Three portions of materials were used, and seven pills were made, and all of them were medium-quality pills. This level should be enough to advance to the semi-finals, right?"

Xu Feng held the pill bottle in his hand and guessed in his heart.

His guess was well-founded. In terms of pill refining speed, he was the third among the 100 contestants to refine a pill.

In terms of the success rate, a 70% success rate was already very high, and the quality of the mid-grade pills was not bad. It was very common for many cultivators to refine new pills and produce low-quality pills.
