The first time he refined the Blood Thread Frost, Wang Lung didn't plan to succeed immediately, although failure is the mother of success, but the number of failures must be something that Wang Lung can bear, the reason is very simple, there is not much time left for him.

Before the two brothers left, Likong had said to Wang Lung that he must leave a month to refine the pill, no matter what the situation of the spirit grass refining, he must ensure that the time for alchemy must be sufficient.

This is an admonition to Wang Lung and an admonition, this is experience, Wang Lung does not have any experience in alchemy, the Chinese medicine he originally learned with the old ghost is of no use to the current alchemy, he knows nothing about alchemy, Wang Lung can only follow the empty advice, he doesn't want to ruin the entire experience because of his arbitrariness.

Failure is not terrible, the key is continuous failure, when Wang Lung and a brother went to Tianjing Star on the way, they once asked Han Yan to help replace the earth fire and refine some spirit grass, at that time the number of spirit grass refined was not much, but there are still many precedents of success, now it is good, it has not succeeded once, Wang Lung looked at the blood reliever frost that had turned into a small pile of ashes on the ground, and his brows couldn't help frowning.

There have been more than fifty blood rex frost was refined, not successful once, Wang Lung was a little depressed, at this time he had stopped the movement of his hand, the Dan furnace was still resting on the ground fire and slowly calcined, and his hands did not touch the Dan furnace, the right hand side was a bunch of fresh blood rex frost, and the left hand side was the blood rex frost that had become ashes, look at the right and then look at the left, after the most disillusionment Wang Lung shifted his gaze to the Dan furnace, his eyes were staring at the red earth fire, and he couldn't help thinking in his heart.

Replace the earth fire with the cold rouge, the cold rouge will release the corresponding energy according to the temperature of the earth fire for refining, and even if the temperature in the Dan furnace changes during the period, it is only a few degrees. But now it is different, the cold rouge cannot continue to replace the earth fire, and the temperature of the earth fire has a difference of about 20 degrees, and this gap is the most critical.

The effect of the temperature difference of two or three degrees on the Dan furnace may be minimal, and when the temperature difference increases to about 20 degrees, the Dan furnace will alternate between hot and cold in a short period of time. The temperature inside can vary greatly.

How to control the temperature difference of the earth fire, Wang Lung can't do it for the time being, after all, he is not a cultivator, and his divine sense cannot leave the body, but he thought of a very critical problem, that is, heat conduction, that is, whether the temperature change in the Dan furnace occurs at the same time as the temperature change of the earth fire, which is the key to the problem.

The fifty blood thorn frosts were all scrapped, not because Wang Long's skills were not up to par. The key is that the temperature inside the Dan furnace cannot be accurately controlled, the temperature difference of about 20 degrees, Wang Long's palm is attached to the furnace wall, when he feels that the temperature of the earth fire begins to change, but the Dan furnace does not change with the temperature of the earth fire in time.

This should be the so-called heat conduction, and Wang Lung is not very clear about this, after all, the change of temperature difference has a delay in the transmission process, and it is impossible for the earth fire to just change. There was a reaction inside the Dan furnace, which was not logical.

One more point. Wang Lung also thought of it, that is, the earth fire has a temperature difference of about 20 degrees, whether the temperature difference inside the Dan furnace is also about 20 degrees, after all, the Dan furnace is calcined on the ground fire after the lid is sealed, and it is a closed space, will there be such a thing as heat preservation. This insulation does not refer to a constant temperature, but the difference in temperature is smaller than that of the ground fire.

The reason for this idea is that Wang Lung saw the Dan furnace and thought of the pot used by Qing'er when cooking, as for whether the above two inferences were accurate, Wang Lung couldn't make up his mind. You can only do it after you have tried it.

Anyway, it has failed many times now, and most of the time has been wasted, if you continue to refine it according to the original method, I am afraid that there will be no possibility of success, if one of these two speculations can be confirmed, then it will be easy to do next.

Thinking of this, Wang Lung no longer continued to be stunned, raised his hand to pick up the top cover of the Dan furnace, grabbed a blood thorn frost at random with his right hand and put it into the Dan furnace, and after re-closing the lid of the furnace, his palm was attached to the Dan furnace again.

Just when Wang Lung was distressed by his failure to refine, the two brothers sat under Zhonghui like pins and needles and listened to his instructions.

It can't be said to be an instruction, mainly because Zhong Hui's temperament and way of speaking made the two brothers unacceptable for a while, just like the rumors about Ao Qing, the first brother's understanding of Zhong Hui is limited to rumors, ordinary chat, Zhong Hui is also calm, just like the elders are amiable and ask the juniors, but such an expression fell in the eyes of the two brothers, and they couldn't bear it for a while, which was completely two extremes with Zhong Hui's treatment of Wang Lung.

"Tell me, what hardships did you go through when you accompanied Wang Lung out of the city this time?" Zhong Hui asked with a smile.

After squirming his itchy throat, the corner of his eye caught a glimpse of a look of reluctance to say more, he could only cough dryly and bow down and say: "I can't mention the tribulation, during this period, I helped Xiaolong build a Dan furnace, and went to those three planets, mainly Xiaolong himself went to collect spirit grass, and we had nothing to do with it, our brothers were waiting in outer space, meditating and cultivating in their spare time." ”

Zhong Hui chuckled and shook his head and said: "What is the situation of the two of you, I can guess as soon as I guess, this is against Wang Long's experience, you must not make a move, I am not asking you, it is that kid." ”

One by one was stunned and said: "We know about Xiaolong's affairs, and we went to collect three kinds of spirit grass, and what we experienced, Xiaolong didn't hide it from us, and told us everything." ”

Seeing Zhonghui nodded, he continued: "We went to the Celestial Essence Star first, and after arriving at the Celestial Essence Star, our brothers separated from Xiaolong, Xiaolong went to collect the Blood Frost, and I and I went to find a suitable Earth Fire to help Xiaolong build the Dan Furnace, and later I heard from Xiaolong that the Blood Frost of the Celestial Spirit Star was ......."

There was no concealment, and Wang Long's experience in the Celestial Spirit Star, Green Plains Star, and Gleth Star was told as it was, and when he was talking, Zhong Hui had been listening, and even if he had questions, he didn't speak, but there were some changes between his eyebrows, and he didn't interrupt them.

After the statement was finished, Zhong Hui fell into deep thought, and this silence passed for more than an hour, which made the two brothers confused at all, and their hearts were flustered, for fear that they would say something that they shouldn't say and make Zhong Hui angry.

More than an hour passed in the torment, and when Zhonghui spoke again, the two brothers were relieved.

"Are you sure that by the time you left the Green Plains, all the remnants of the Soul Breaker had been wiped out?"

Without waiting to speak, he said, "Senior, when we and Xiaolong left the Green Plains Star. Xiaolong listened to Du Lian's predecessors say that the Soul Splitting Clan was only the cultivation of the Yuan Infant Stage, and from the beginning of its discovery to the time Xiaolong found its hiding place, the total number of puppets controlled by it had reached saturation, and all the puppets were strangled, even if the Soul Splitter Clan was still alive. It doesn't do any harm. ”

Zhong Hui nodded and said: "That's true, but the Soul Splitting Clan has disappeared for so long, we all thought that the race had been extinct, but it could reappear in the Saint Source System, this has to be taken seriously, how many trillions of years have passed, the Soul Splitting Clan can still survive to this day, and no one can say what happened during this period." Whether there is a new mutation in the Soul Splitting Clan, it is also not clear, you say that Du Lian got the information from the ancestor, which I believe, but the information in the hands of the ancestor is only the information from trillions of years ago, trillions of years, this time is not short, and it will not be strange if anything happens during the period. ”

One asked, "What does the senior mean?" The Soul Breaker is no longer the original Soul Splitter, it may be a mutant. ”

Zhong Hui shook his head and said, "All this is just my own speculation. I hope not, the horror of the Soul Splitting Clan I have only recently learned about the Dao, a race that can be feared by all races in the universe, what is hidden behind it, no one dares to draw conclusions. ”

After a glance, I saw the other party nodding. With a long sigh, he said: "It's a pity that we have been away from the Green Plains Star for more than half a year, and during this time, we can't verify whether the Soul Splitting Clan has been wiped out as Du Lian's predecessor said. And I also believe that if there are any strange changes in the Soul Splitting Clan, Senior Du Lian will not know about it and not report it. ”

Zhong Hui nodded and said: "Yes, but I haven't been able to calm down in my heart, I have to confirm it, so let's do it, you two can stay here and meditate, and when the little guy comes out, I will go out of Lu first, and I will be back in a few days, if Wang Lung comes out in advance before I come back, you will wait here first, as early as three or two days, or later it will not be more than half a year, I will definitely come back." ”

One said: "In this case, go ahead and go, our brothers will wait here." ”

Zhong Hui nodded lightly at the two brothers and disappeared, and the two brothers were not surprised to see this, but they just glanced at each other and did not say anything, so the two closed their eyes on the spot and began to meditate.

At this time, Wang Lung was looking at the crimson liquid in his palm, and there was a faint smell of blood and a pungent smell of putrid acid in his nose, although the refined blood cream did not smell very good, but Wang Lung didn't care, this was a time when he finally succeeded.

After nearly 100 failures, Wang Lung finally found the knock on the door, and the two possible tests he guessed at the beginning were not ideal, and they were also one kind of ending, that is, failure.

At the beginning, Wang Lung guessed the temperature change in the Dan furnace according to his own guess, and the temperature difference between the ground and fire could reach about 20 degrees, Wang Lung guessed that it was impossible for the Dan furnace to have no change at all, and it was impossible to reach a temperature difference of 20 degrees.

Coupled with the initial failure, after nearly a hundred failures, Wang Lung finally succeeded in refining the essence of the Blood Lotus Cream, although he only succeeded this time, but Wang Lung knew in his heart that a success did not mean anything, maybe the next time it would still fail, but with this success, the original guess was correct, only by mastering the law of temperature changes in the earth fire and Dan furnace could he successfully refine the essence of the spirit grass.

Time flies very quickly, it is very close to the one-year time limit given by Zhong Hui to Wang Lung, Wang Lung has not yet come out of the earth fire room, Zhong Hui has also left the North Pole for a while, except for the two brothers who have been meditating, Wang Lung and Zhong Hui have not appeared.

"Xiaolong should be coming out soon, the one-year deadline is coming soon. ”

Hearing the empty question, he slowly opened his eyes, nodded lightly and said: "It is estimated that in a while, Xiaolong should appear, if he forgets the time for alchemy, we can't ignore it, remind him at that time, whether he can succeed or not depends on himself." ”

He nodded and said: "Yes, whether it is successful or not, even if you give Xiaolong more time, it will be in vain, he is not a cultivator, his divine sense cannot be separated from his body, Pei Yuan Dan is too difficult for him." ”

For a while, the two brothers fell silent, they naturally hoped that Wang Lung could pass Zhonghui's level, but they also knew very well in their hearts that Pei Yuan Dan was a piece of cake for cultivators, but for Wang Long, who was not a cultivator, it was comparable to ascending to the sky.

If Wang Long's alchemy fails, the consequences will naturally be self-evident, and the two brothers, as the accompaniment of Wang Long's refining, will not end up much better, but unfortunately, at this time, it is not only a test for Wang Lung, but also a test for the two brothers.

"Look at the sad faces of you two here, what the hell is going on?"

Hearing the question, the two brothers were stunned, looked at the voice, their faces suddenly showed joy, and they shouted in unison: "Xiaolong." ”

"Xiaolong, how are you coming out?" asked Sora when he couldn't hold his breath, got up and took two steps to grab Wang Lung's shoulder.

Wang Lung didn't answer immediately, but gave the other party a faint smile, raised his hand and gently patted the arms that were empty on his shoulders, and nodded at the head that was walking towards him, the expression on his face was always the same, so that the two brothers didn't know why.

Watching Wang Lung walk past him, he followed him anxiously, and his mouth opened several times and was blocked.

After Wang Lung sat down, he glanced at the two brothers meaningfully, then looked at the main seat, and asked suspiciously: "Why is Zhonghui'......s predecessor not here?

Without waiting for Wang Lung to finish speaking, he interjected and said: "Senior has something to go out, Senior Zhonghui said before leaving, if he hasn't come back when you leave the customs, let's wait for a while, but don't worry, the time won't be too long, at most half a year." ”

Wang Lung nodded after hearing this, and just wanted to say something, but there was an anxious question in his ears: "Xiaolong, don't be angry, has your Pei Yuan Dan been refined?"

Hearing Kong's question, Wang Lung laughed self-deprecatingly, did not answer immediately, and took out a delicate green jade porcelain bottle from the storage spirit vessel with his backhand, and handed it to Kong.

He took it in surprise and asked in astonishment, "Is this ...... This is a waste pill, you didn't succeed?" (To be continued......)
