"Grandpa, what's going on?!" A delicate voice sounded, and a beautiful woman in a pale green dress squeezed in front of the white old man Mu Xuan, her eyes flashing with gossip.

Mu Xuan waved his hand without looking back, signaling his granddaughter Mu Qiao not to make a noise, but his eyes were firmly fixed on Xia Qinglian, who entered the sixteenth test room, for him, Qinglian was a good seedling who was really suitable for alchemy!

Behind the green-clothed beauty Mu Qiao was followed by a tiger-headed young man, and after seeing that the red old man was actually present, he could only say hello stubbornly: "Grandpa! Why did you come to Danmeng?!"

This tiger-headed young man is actually the grandson of the old man Huohou, and his name is very individual, called Volcano!

The old man glanced at his precious grandson, his eyes seemed to stay on the four-leaf Dan League badge on his chest for a moment, and the corners of his mouth twitched before he replied angrily: "Hmph, you stinky boy, it's just a matter of following Mu Qiao, this little girl, all day long, you only wear the four-star badge of the Dan League, and you don't even wear the badge of our Instrument League?!"

This volcano has liked Mu Qiao since he was a child, and the two of them are also world friends, childhood sweethearts!

In order to pursue Mu Qiao, he can be said to have changed his way to please her, in addition to following her like a fart in the Danmeng every day, he also put down a lot of time to learn refining weapons.

You must know that this kid was born with a great talent in refining, and he can reach the strength of a five-star refining weapon without much effort in refining it, so he is deeply valued by the old man, but unfortunately this kid abandoned the refining tool for a girl, which made Huo Hou almost vomit blood in anger.

"Hehe!" Volcano scratched his head slightly embarrassedly and laughed, and a five-star level Instrument Alliance badge appeared on his chest, right next to the Dan League badge, and then continued to ask: "Grandpa, what is going on here? Why did you and Old Man Mu come to the test hall on this floor?!"

"Look quietly, don't talk nonsense!" Huo Hou grinned, didn't bother to explain anything to this unsuccessful grandson, just threw down a sentence angrily, and stared intently at Du Long in the fifteenth test room, which was a dish in his photo.

Just when Du Long and Xia Qinglian were standing in a test room and looked a little at a loss, the old man Mu Xuan finally spoke: "Dan Ling!

After hearing Mu Xuan's arrangement, many people at the scene understood what he wanted Du Long and his wife to test, but Du Long and the two of them were confused.

On the white jade platform, the golden light array flashed, and three cyan blue palm-sized fruits appeared, flashing with a faint blue light!

"The two of you will refine the three green dragon fruits into impurity-free fruit liquid and fruit powder, and allow one failure!" Seeing Du Long and his wife looking at the three green dragon fruits in a daze, Mu Xuan explained with some amusement.

Du Long suddenly understood the goal of this test, but he was still a little unclear, so he pressed his left hand on the Ding furnace away from the fire, injected the immortal fire in his body into it and began to heat the Ding, and at the same time, he also secretly asked the ring spirit about the goal of this test.

As a result, Ring Spirit Ling'er's answer was also simple: "I don't know anything about the nature of your immortal medicinal materials in the immortal realm for the time being, you can feel it carefully after you carefully refine it!"

In other words, Du Long now has to rely on his strength in Dandao to feel the fire resistance of this green dragon fruit on his own!

In the standard Danding, the work of the hot ding was completed quickly, this step is the simplest, basically you can turn on the fire to your heart's content, but you are not afraid that your own Xianyuan fire will burn out the Ding furnace!

Locked on a blue dragon fruit on the white jade platform, he sucked it up in the air with a wave of his right hand, and then threw it into the dingzhong with a single draw, and under the scanning of the immortal sense, Du Long controlled the temperature of the immortal yuan fire and swept it into the fire.

After controlling the temperature of the flame and observing it for a long time, he saw that the green dragon fruit had reached the temperature of the flame, but the surface had not changed at all, so he confidently and boldly began to raise the flame temperature, wanting to find the flame temperature of refining the green dragon fruit.

From one percent of the temperature gradually warmed up, two percent, three percent ...... It wasn't until the temperature reached about seventy percent that the green dragon fruit, which had not moved all the time, finally reacted!

Whoop, whoop......

Liquid began to gush out from the surface of the blue-blue peel, making a sizzling sound under the burning of the flames, and Du Long maintained this temperature point, quietly waiting for the liquid inside the green dragon fruit to be gradually forced out.

This process lasted for about half an hour, which was too easy for Du Long, and he didn't see half a drop of sweat on his forehead, which alone made the red and white old men nod secretly.

Soon, the fruit juice inside the whole green dragon fruit was completely forced out, and the husk that lost the fruit juice quickly turned to ashes, and was driven out of the waste residue hole at the bottom of the Danding by Du Long.

The next work is not complicated, it is to raise the temperature a little and continuously refine the impurities inside the fruit juice until it no longer has impurity bubbles, and a mass of energy liquid without impurities will be completed in about an hour!

Skillfully turned over his hand and took out a jade bottle, and after leading out the ball of energy liquid in the Danding and loading it, Du Long began the next round of work, the previous steps were the same as just now, but in the end, he did not stop after refining the energy liquid without impurities, but suddenly increased the flame, continued to refine the ball of fruit liquid, and finally saw that it was about to turn into a small pinch of medicinal powder and quickly lowered the temperature until the powder was formed!

As a result, it only took a little more than two hours before and after, and Du Long completed the task requirements of one liquid and one powder, and there was only one green dragon fruit left without wasting at all!

Casting an inquiring gaze at the two elders of Red and White, after seeing them nodding, Du Long secretly breathed a sigh of relief, walked out of the fifteenth test room, and began to watch Xia Qinglian, who had not yet completed the task, busy there.

In recent years, Qinglian has often followed Du Long to refine the alchemy in the Qinglang Cave, maybe it is really a matter of talent, she is not interested in refining, but regards it as a task to complete.

However, in the elixir, her achievements are not too low, although they are a lot worse than Du Long, but they are also chasing closely step by step, and the gap between the two is slowly narrowing.

About three hours or so, after Xia Qinglian wasted a piece of green dragon fruit, she finally completed the task assigned by Mu Xuan, the leader of the Dan League, and at this point, her forehead was already sweating!

"Haha! Very good! Being able to successfully refine the Bilong Fruit means that the Immortal Yuan Fire in your body has reached at least the four-star level, presumably the Immortal Yuan Fire in your body should be almost consumed at this moment, right? Therefore, the next test is no longer about endurance, but about the explosive power of the flames! Dan Ling, give each of the fifteenth and sixteenth test rooms an Ice Heart Fruit!" Mu Xuan stroked his white beard and smiled heartily, and immediately began to arrange the next step of the test.

When a light blue fruit appeared on each of the two white jade platforms, and a chill began to permeate the test room, Mu Xuan spoke: "You two are now starting to refine this Ice Heart Fruit at the fastest speed, remember, it is the fastest speed with the maximum flame temperature, the faster it means the better the results!"

In the two test rooms, Du Long and Xia Qinglian heated up the Ding again, and then threw the Ice Heart Fruit that exuded an icy aura into the Ding, and instantly opened up the firepower, and the Fire Dragon wrapped the Ice Heart Fruit in one roll.

Whew, whew, whew!

In the standard furnace in the two test rooms, an orange-red and a light blue flame is burning, one is scorching, the other is strangely cold, and the two extremes can produce the effect of flame burning.

When refining the elixir, Du Long rarely had the opportunity to turn on the firepower, and often when the firepower was at full power, the elixir would be refined into ashes in the blink of an eye!

When refining this Ice Heart Fruit this time, although the speed was not so fast, it was not slow at all, and the Ice Heart Fruit the size of a ping-pong ball was like an ice ball falling into boiling water, which began to melt rapidly, and soon vaporized without a trace.

Stunned, he stopped sending flames to the Ding Furnace, and just when Du Long thought that he was not too strong and refined an immortal elixir, a crisp voice sounded in the hall: "In the fifteenth test room, the time for refining the Ice Heart Fruit is between nine breaths, and the flame quality and strength are superb!"

Wow......

When Du Long was refining the Blue Dragon Fruit before, none of them felt anything, but after hearing the announcement of the array spirit at this moment, they immediately became in an uproar, it was obvious that it would definitely not be easy to refine an Ice Heart Fruit in such a short period of time!

Especially the red old man was even more happy to dance, the excitement was beyond words, Mu Xuan on the side was depressed, but he didn't say anything, but continued to focus on Xia Qinglian's test.

Withdraw, the light blue flame dissipated invisibly, Xia Qinglian's test was finally over, and the white old man Mu Xuan finally breathed a sigh of relief, and an excited smile appeared on his face, obviously still very satisfied with the test result!

"In the sixteenth test room, the time to refine the Ice Heart Fruit is twenty-one breaths!The flame quality and strength are superb!" The dutiful voice of the array spirit sounded again.

"Yes, yes!Old man Mu, this girl in your picture is cultivating a cold flame with the same yin attribute as you, and she can refine the Ice Heart Fruit in twenty-one breaths, and the effect is definitely no worse than that kid!"

Mu Xuan nodded, and didn't say anything more, but explained to the array spirit again: "Dan Ling! Send the fifteenth and sixteenth test rooms a fifth-grade and sixth-grade thick spirit vine respectively!"

As his voice fell, on the white jade platform of the test room where Du Long and Xia Qinglian were, two more things like earthy yellow dead branches immediately appeared, but one was slightly lighter in color, and I didn't know what kind of strength these two things were testing!
