After Chu Ran returned to Green Island City, he contacted the Yanzhen Daoist and the Master of Void Phase, and prepared to refine the elixir in the square of the apse of the Yuqing Palace. But when everything was ready, he began to review the relevant knowledge about alchemy in his mind, only to realize that refining the elixir required spiritual fire to quench, and spiritual fire was naturally born between heaven and earth, and it was difficult to discover, let alone subdue it. If there is no spiritual fire, the spiritual energy can be converted into spiritual power when the cultivation reaches the yin and yang realm, and then the divine fire generated by using the fire system technique to ignite the spiritual power can also be used for alchemy, but the refining ability is much lower than the spiritual fire. Suffering from the lack of alchemy spiritual fire or divine fire, Chu Ran entered the sea of knowledge space to ask Taixuan for help.

Tai Xuan almost didn't stand firm, and then he reacted, it is true that alchemy requires the use of spiritual fire or divine fire, and there can be no spiritual fire on this blue star, and Chu Ran, who is suppressed by the rules of the Hongmeng Star Domain, cannot reach the Yin and Yang Realm, and he did not inform Chu Ran of these basic cultivation knowledge in advance, so Chu Ran is indeed unable to open the furnace for alchemy. So Tai Xuan thought for a while and then said, "In vain, you can only replace it with thunder fire." ”

Chu Ran fluttered with a pair of big sparkling eyes, and asked puzzledly, "Thunder Fire?" What kind of fire is that? ”

"As the name suggests, it is the fire generated by the thunder, you go and prepare some wood, and when the thunderstorm weather, the teacher will lend you a trace of fairy, and you will float the fairy spirit on the wood, when the thunder is in full bloom, affected by the rules of the Hongmeng Star Field, the thunder will frantically attack the wood with a trace of fairy spirits attached, so that you can get the thunder fire."

Hearing this, Chu Ran immediately bowed to Taixuan and said, "Understood, Master, then you will lend me the fairy spirit." ”

Seeing that Chu Ran was so eager, Tai Xuan replied a little angrily: "In vain, don't be in a hurry, you need to wait for a thunderstorm to work." "You must know that although Taixuan is not stingy with a trace of immortals, if it is not for the thunderstorm, as soon as the immortal spirit comes out, it will be immediately suppressed and dissipated by the laws of heaven and earth in the Hongmeng Star Domain.

Just as Tai Xuan wanted to continue to reminisce about the feelings brought to him by Wen Nourishment, he heard Chu Ran reply: "Master, there is lightning and thunder outside. ”

Taixuan felt like he was about to flip the table: this damn bad luck, how could it be so coincidental to catch up with a thunderstorm. Tai Xuan reluctantly stripped off a trace of immortal spirit and handed it to Chu Ran while thinking about it, it was not that Tai Xuan was unwilling to give it, but Chu Ran's luck was too against the sky, and whoever saw it would be jealous. After getting a trace of Taixuan's immortal spirit, Chu Ran happily bid farewell to Taixuan and returned to the real world.

In the apse, Chu Ran, who was sitting on the futon, opened his eyes and said to the two people in front of him with a happy face: "There is a way, we can lead the thunder and lightning down and ignite the wood, and use the thunder fire alchemy." ”

The two of them looked at each other, and at the same time thought to themselves, 'Can you still do this?' But Chu Ran was a senior after all, and there were also two sect leaders who asked these two to fully assist, so the two of them didn't ask more questions and acted according to Chu Ran's thoughts. After a while, several little Taoist priests were busy for a while, and some wood was piled up in the square, Chu Ran turned the aura of his whole body, and attached a trace of fairy spirit borrowed by Taixuan to this pile of wood. Chu Ran mobilized the aura again, using the technique of taking things from the air, to introduce the thunder fire into the Danding, and then according to the tutorial of alchemy, the spirit plants were thrown into it one by one, and after covering the furnace and injecting a trace of aura, the three of them retreated to the apse.

Back in the apse, Chu Ran said to Yanzhen Daoist: "According to the alchemy taught to me by my master, these pills need to be refined for seven days, and I will stay in this apse for these seven days, and please don't mind Master Yanzhen." ”

For any of Chu Ran's requests, the Yanzhen Daoist agreed unconditionally, so he replied: "Immeasurable Heavenly Venerable, the seniors can treat this place as their own home, the poor Dao and the void phase master will retreat, and the poor Dao will arrange for the Dao Tong to prepare three meals for the seniors, and no one will disturb the seniors for alchemy the rest of the time." ”

When Chu Ran heard this, he was grateful to Yanzhen Daoist for his thoughtfulness, so he bowed his hand and said, "It's so good, then it will cause trouble for the master." ”

Yanzhen Daoist and Master Void Aspect gave a salute to Chu Ran and did not leave, just when Chu Ran was puzzled, Master Void Phase opened his mouth and asked: "Dao Xuan senior, please forgive the poor monk for being rude, the poor monk wants to ask the senior, this Dan furnace can actually change out of thin air, is it the same technique as the predecessor summoning the sword when Yan Du fought the law that day?" There is also the fact that the poor monk's view of this Dan furnace is extremely unusual, can the seniors explain one or two to the two of us? ”

Hearing this, Chu Ran suddenly realized that he had just moved the Xuanlong Ding directly from the Zhihai space, and it was indeed the same as calling out the Xuandao Sword that day, giving others the feeling that it was all changing out of thin air, because the Blue Star cultivation exercises and systems were different, so Chu Ran explained like this: "Two masters, Chu Mou can't explain the principle of this technique, please understand." As for this tripod, this is the Xuanlong tripod given to me by the master and his old man, and I heard that it is a Dan furnace used by immortals! ”

Hearing this, the two masters understood Chu Ran's difficulty, and were shocked again when they learned that this Dan furnace might be an immortal product. After giving Chu Ran another salute, the two masters withdrew from the apse, leaving Chu Ran alone to meditate and alchemy.

Time flies like a white horse, and seven days have passed in a flash. On this day, Chu Ran, who was sitting in the apse meditating, opened his eyes, and then stood up and walked towards the square. At this time, on the square, Yanzhen and Void Xiang had long been unable to bear the excitement in their hearts waiting here, although the Cultivator Sect had always had a heritage of refining pills, but how could ordinary pills be compared to the elixir refined by Chu Ran, let alone from the furnace used by immortals.

Passing by the two of them, Chu Ran nodded to the two, and then walked to the front of the Xuanlong Ding and stood still, with two fingers together, running the aura, opening the lid of the tripod, and suddenly, a fragrance came into everyone's noses. Yanzhen Daoist and Master Void Phase sniffed it at the same time, and instantly felt refreshed and full of energy, and their hearts were amazed. Refining the elixir is not an easy task, especially for the first time like Chu Ran's attempt, the rate of Cheng Dan must not be high, Chu Ran used all the medicinal materials, which can be compared to thirty Cheng Dan, and these medicinal materials are placed in Tai Xuan's hands, they can become eighty or ninety pills.

Chu Ran used the aura to retrieve things from the air, put all the elixirs into the wooden box that had been prepared, and said to the two of them embarrassedly: "Two masters, I didn't expect to put all the spiritual elixirs into it, and it took thirty pills to become a pill. ”

Yanzhen Daoist looked at the wooden box containing the elixir with trepidation, and said excitedly, "The predecessor is humble, I think my Blue Star aura is thin, and my cultivation is declining, and it is really God's favor to be able to appear these thirty spirit pills." ”

At the same time, the Master of the Void Phase was also very excited, so he asked tremblingly. "Amitabha, dare to ask your predecessors what is the name of this elixir?"

Chu Ran smiled mysteriously: "This pill is called the Life Pill, it has the effect of gathering souls and living beings, taking one can be worth a year of penance in Blue Star." ”

It has such a miraculous effect, it is really an elixir that is not born in the world!
