Li Hong learned from the pain, and after thinking about it repeatedly with everyone, he thought that it was because the Dan furnace was not good enough.

This Xiao Dan furnace can refine human-grade Dan at most, but refining Earth-level Dan really can't withstand the huge amount of aura when the Dan is about to become a pill, which eventually leads to an explosion.

And also...... Touching somewhere in private, he secretly called it a fluke, and made up his mind that he would never hang upside down on the beam like a monkey again, this method was too stupid. I can't regret it!

The three of them cleaned up the fragments of the exploding Dan furnace piece by piece. In the end, these are the gold and iron outside the sky, which can be re-smelted. When the collected fragments were placed in front of Yue Changzi, he picked up a piece and took a closer look, and suddenly pointed to the fragment and said, "Look!"

Yun Jiuzi Li Hong took a closer look, and at the same time sighed in surprise.

The debris was covered with extremely fine cracks from the explosion, and there were many crystalline black liquid stains on the inside. These aura-rich black potions were strange, and they were automatically seeping into the cracks of the fragments, and some of the smallest cracks were disappearing. It gives the impression that the liquid is closing the cracks.

Li Hong's heart moved, and he laughed and said, "This is simply a liquid made of thick spiritual energy. If we use these fragments to build a new Dan furnace, I guarantee that the new Dan furnace grade can definitely be upgraded by one level. If the previous one could refine human-grade Dan, the new Dan furnace made from these fragments would definitely be able to refine Earth-level Dan. ”

"That's right!" Yue Changzi was overjoyed. This time, I didn't feel heartache anymore, and took the initiative to go to the warehouse of the Instrument Hall to take out fifty catties of Tianwai gold essence iron, plus the best bone water soft sand and the best fire jade essence, and began to build a new Dan furnace.

With the successful experience of the last time, it only took four days to build the Xindan furnace successfully.

The color has changed radically, no longer yellow with red, but purple-black, the surface is still red and flowing, it looks more powerful than the previous one, and it is also larger, with a diameter of two feet, which can hold more medicinal liquid.

The first furnace of Bigu Dan was easily successful, and there were many more pills than before.

If the previous Dan furnace can only barely be counted as a low-grade magic weapon, this is at least a medium-grade magic weapon. The crowd couldn't be more satisfied.

The four elders automatically asked for help again, and the second refining of the Qiankun Righteous Qi Pill entered the countdown.

According to Yun Jiuzi, the Qiankun Righteous Qi Pill also has a name, called "Heaven Snatching Creation Pill", one of the functions is of course to turn the miscellaneous medicinal power into its own cultivation, but there are several wonderful uses. One of the things that is very helpful to Yun Jiuzi is that the Qiankun Righteous Qi Pill can quickly replenish spiritual power when fighting against the Heavenly Tribulation, and a single pill can restore a very serious injury.

Hearing him introduce like this, the four elders were only afraid that they would not be used for alchemy, so they waited diligently next to the ghost stream early, and looked at Yun Jiuzi's eyes with reverence as if they were looking at heaven and man.

In order to ensure the success of this time, Lingxuzi sent the people in charge of the Torture Hall to guard around the Golden Lantern Gorge of the Ghost Stream. A radius of ten miles is designated as a forbidden area. At dawn, in the open space of the Ghost Stream Plain Hut, the second refining of the Qiankun Righteous Qi Pill officially began.

After the Dan furnace was preheated, the lid of the furnace popped up, and Yun Jiuzi had the experience of distributing medicine last time, and this time it was more secure. With his hands lightly, a kind of immortal grass was thrown into the medicine room in an orderly manner, and the thick green medicinal liquid slowly rose again.

After the seventy-seven kinds of immortal grass were distributed, Yun Jiuzi finally crushed the half of the longan flower and threw it in, quickly waved in three drops of rejuvenating maple juice, and closed the furnace lid.

The four elders didn't dare to be careless at all, and immediately turned to a medium amount of spiritual power input at the same time, and Wen Dan began.

This process is the longest and most spiritually demanding. Yue Changzi once again took Huo Yuan Dan and Qing Shui to serve aside. Li Hong learned to be obedient this time, sitting high on a wooden platform temporarily erected in the distance, sitting cross-legged condescendingly, and the colored light tentacles stretched over and coiled on the Dan furnace.

The four fields were empty, except for the sound of the whimpering water of the ghost stream and the whirring and turning sound coming from the Dan furnace. Everyone is waiting for the enemy.

Red light flashed from the surface of the Dan furnace, and the purple-black furnace body was full of aura, with only an extremely slight tremor. The furnace still seems to be very stable and sturdy until now.

Three days have passed, and Wendan has completed seven or eight out of ten. The strong medicinal fragrance began to diffuse, and even the people who were in charge of the torture hall ten miles away couldn't help but sniff hard.

This smell is very fragrant, with a little bit of wine, indescribably fragrant, and I feel awake when I smell it.

At this moment, Li Hong shouted in a deep voice: "Attention, the fried Dan is about to start!"

He "saw" that the passage between the Wendan room and the fried pill room was slowly opening, and the entire Wendan room began to turn upside down, and wisps of thick medicinal liquid dripped into the fried dan room below. After the dropping of the medicinal liquid, the Wendan room was immediately unscrewed, and the frying of the Dan began.

Li Hong shouted: "Change the minimum spiritual power input!"

The four elders let out a long sigh, cooperated with each other tacitly, and at the same time converted into a small amount of spiritual power and slowly input.

This is the most critical part, success or failure at this moment!

Everyone present was tightened, and Li Hong felt his heart pounding.

It didn't take long for the fried dan room to start banging. Li Hong clearly "saw" that the elixir that had been refined was automatically forming and bouncing one by one, spun around the entire frying pill room like a fly, and jumped towards the pill room along the passage one after another.

There was a huge earthquake in the Dan furnace, and a trace of white steam overflowed out of the furnace cover, rotating and swirling on the entire Dan furnace body, like a white dragon.

Yue Changzi's eyes widened when he saw this, and his hands clenched involuntarily, almost wanting to stuff them into his open mouth.

Li Hong shouted: "Stop now!"

The four elders had been waiting for Li Hong's order for a long time, and when they heard this, they immediately stopped at the same time.

Whew - a large amount of white steam rushed out of the lid of the furnace, and rose to the sky with a strong danxiang. In the white vapor like a long rainbow, dozens of tiny projectile black dots can be clearly seen jumping around.

"Pick it up, you fools!" Yun Jiuzi hurriedly shouted, and he had already copied a white jade box in his hand, chasing after those extremely naughty little black dots that were bouncing around.

Everyone immediately woke up, laughed and joined the ranks of chasing Dan, and took out their belongings one after another. Li Hong was no exception, flying around with a jade bottle in his hand.

It's weird! These elixirs are jumping around as if they have long legs. The innermost ones were copied by everyone, and the farthest ones jumped to the side of the person in charge of the torture hall ten miles away.

Seeing that Yun Jiuzi and the others were all busy, no one seemed to pay attention to this, and his eyes rolled and he took out a small jade bottle with a cover, and finally covered the Qiankun Righteous Qi Pill that flew in front of him. Bowing his head and approaching the jade bottle, the refreshing sweet aroma hit, he was so happy that he didn't know what to do, so he quickly put it in his sleeve.

A black shadow flew forward, and Yun Jiuzi walked in front of him with a tiger face, glaring and shouting: "Boy, who are you?

This person's chest suffocated, and he almost fell into the dust on the spot, and shouted in fright: "The disciple is just helping!" raised his hands and offered the jade bottle.

Yun Jiuzi snorted coldly and snatched it, turned around and left. The coercion suddenly disappeared. The huge force in his chest shook back, and this disciple almost didn't hold his breath on the spot, his face was as white as paper, and his heart and liver were beating with fright.

With such a small episode, Yun Jiuzi didn't dare to relax, and almost flew around the field, not a single grain escaped his ears and eyes.

In the end, all the elixirs received were summarized, and Yun Jiuzi counted them, and he smiled with joy: "Forty-seven grains! There are so many!"

"It shouldn't be put together. Li Hong reminded.

Everyone looked into the jade box, and immediately amazed, only to see all the elixirs flying around like a fight inside. None of them were honestly left alone.

Li Hong said with a smile: "This must be due to the fact that the spiritual energy contained in the elixir is too strong. ”

"Yes, yes, a jade bottle of Qiankun Righteous Qi Pill is enough, so as not to be damaged. Yue Changzi took out dozens of jade bottles with his hands and feet, and packed the Qiankun Righteous Qi Pill one by one.

The four elders first received one grain from each of Yun Jiuzi, and resigned first with a smile.

Yun Jiuzi handed Yue Changzi three more grains, and said with a smile: "You have made a great contribution this time, take it!"

Yue Changzi took it and looked at Li Hong.

Li Hong had already broken his fingers one by one, and said with a smile: "I want ten grains." ”

Yue Changzi was so frightened that his hands trembled, but Li Hong was so black-hearted, afraid that Yun Jiuzi would be angry, so he hurriedly said: "Little monkey, why do you want so much, Master, I have three here, I only need one for spare, and the other two will be given to you." ”

Li Hong didn't panic, and looked at Yun Jiuzi with a smile behind his back.

Yun Jiuzi sighed, Chu Xi, Chu Xiong, Chu Xuan, Chu Liang, Chu Hai plus the four surviving disciples of the other veins, Li Hong actually only needs one. Not to mention that it is not easy to refine the Qiankun Righteous Qi Pill, let's just say that the fairy grass on the Danfang has been collected for thousands of years before it has been collected, and it took a total of forty-seven grains to refine it.

Yun Jiuzi smiled bitterly, but the bottom of his heart swept over the smiling and arrogant face of Master Tian Danzi.

He thought for a while, took out the eight jade bottles and put them aside, and crossed the middle of the remaining jade bottles with both hands, just dividing all the jade bottles in half, rolled his eyes and said angrily: "I guess the last one is not reserved for you, but for your spirit stone master, right?

Li Hong laughed: "This is what you said yourself, don't regret it!" As he spoke, he waved his hands and moved half of what Yun Jiuzi gave him into Qiankun Kui without pause, which was exactly sixteen bottles and sixteen pills.

He immediately raised his sword and laughed, "I'm afraid you'll regret it, I'll go first!"

Yue Changzi opened his mouth and looked stupid, came to his senses and hurriedly looked at Yun Jiuzi, but saw that Yun Jiuzi was not annoyed at all, smiled and put away the remaining sixteen bottles, and said to him: "I'll go to Lingxuzi, you can also go back and rest, that baby, you have to take care of it!" Yun Jiuzi pointed to the Dan furnace and went with a smile.

Yun Jiuzi was not angry at all! Yue Changzi sighed secretly, picked up the Dan furnace, and flew to his own hall with a smile.

Alchemy still has to go on. However, it's time to train another group of people to alchemy. Yue Changzi hurriedly began to plan to get up for Jiu Limen.
