Half a month later, Wang Lung and the three of them had approached the Celestial Spirit Star in the flying machine, which was a planet the size of the Earth and a planet of new life, in which the concentration of spiritual energy was about the same as that of the Earth, which was not suitable for cultivation.

Before leaving the earth, Wang Lung learned some information about the Celestial Spirit Star from the old ghost, although this planet is not big, there is still life, and the dominant one is the elves, in addition to the elves, the beasts and humans also have a little, but its power cannot be compared with the elves.

When inquiring about the information of the Celestial Essence Star, the old ghost warned Wang Lung that collecting spiritual grass in the Celestial Essence Star must be in order, and he must not shout and kill, although he cannot achieve the realm of not fighting back and scolding, but he cannot bully the weak.

The Celestial Spirit Star is not comparable to the Earth, and although the aura is thin and not suitable for cultivation, the ratio of the aura and the chaotic qi on this planet is very harmonious, and any damage may make the planet scrapped.

If Wang Lung is bullied in the Celestial Essence Star, it is not impossible to fight back, but he cannot mobilize the aura of the Celestial Essence Star, and he can only use secular martial arts to do it.

This admonition, the old ghost said very solemnly, let Wang Lung remember not to disobey, ask the reason to know that the Celestial Essence Star is the masterpiece of the last great invasion, it turns out that the Celestial Essence Star is not like this, it is a mature planet, when the last great invasion came, the Celestial Essence Star was seriously damaged, I thought that the Celestial Essence Star has become an abandoned planet since then, who knows, the planet still has the ability to generate itself.

Now that the Celestial Spirits are revived, there is a Guardian in charge, also from the Elven Clan, when Wang Lung is active in the Celestial Spirits, the Guardian will not intervene, if Wang Lung dares to disobey the old ghost's warnings, his life may be lost.

Wang Lung knew that he was powerful, and assured the old ghost that not only would he not cause trouble, but he would also not cultivate. Treat yourself as an ordinary person and collect the required spirit grass by peaceful means.

After getting Wang Lung's assurance, the old ghost was very pleased, and at the same time handed Wang Lung a part of the spirit grass he needed, these spirit grass old ghosts didn't have it, if it wasn't for Wang Long's reminder. The old ghost doesn't know what to do.

Those three kinds of spirit grass are worthless to the old ghost, last time Wang Lung was seriously injured by the ankylosaurus, after the injury recovered, the old ghost looted Wang Long, there are some of them, those spirit grasses are still obtained by Wang Lung after killing Hong Yiping, although it is not much, but it is better than nothing.

As for why there was such a low-level spirit grass in Hong Yiping's storage spirit weapon, now the other party was dead. Even if Wang Lung wanted to ask, he couldn't ask, and he could only cheapen Wang Lung in the end.

Those three kinds of spirit grass were not many in the first place, and they only added up to a few dozen, and Wang Lung did not ask for the number of fifteen hundred plants from the old ghost, but for research.

From the earth to the Celestial Spirit, with the ability of the flying machine, it will take at least half a month to arrive, in this short time. Wang Lung didn't have time to be idle and bored, he had two things to do. One is to learn alchemy, and the other is to practice hands.

Learning the art of alchemy is very easy to solve, and emptiness is a ready-made teacher, Wang Lung asked for advice from emptiness, and with his memory and comprehension ability, the art of alchemy was quickly learned. The only fly in the ointment is that it is on paper, he has not refined, everything is just empty words.

Now that there is the spirit grass obtained by the old ghost, Wang Lung can practice his hands, but there is still one thing missing. It is the Dan furnace, this thing must be able to withstand the fire of the leylines or the Dan fire and infant fire of the cultivators, Wang Lung does not have it, so he can only find a one.

A once promised Wang Lung to create a suitable Dan furnace for him, but now in the middle of the flight, I am afraid that I can't get it for a while, but it is just a practice, no need for a special Dan furnace, after getting an ordinary Dan furnace from the other party, Wang Lung let Han Yan come out of his body and use it as a fire source to refine spiritual grass.

Han Yan is now cultivating to a critical moment, and he was called out by Wang Lung to do such a boring thing, and his complaints can be imagined, but in order to help Wang Lung complete the trial, after being depressed, Han Yan had to do what Wang Lung said.

It only took three days to learn the art of alchemy, and the rest of the time was spent purifying the spirit grass.

Han Yan has a Dan furnace on his head, and the body temperature is controlled on the strength of the earth fire, for all the changes in the Dan furnace, Han Yan and a brother will not remind Wang Lung, they can only rely on Wang Lung to go and feel it himself, after all, in the actual alchemy process, no one can help Wang Lung.

As the saying goes, practice brings true knowledge, this sentence is the absolute truth no matter where it is used, Wang Lung learned the alchemy technique from the void, and the theoretical ability is absolutely nothing to say, but only when you really start to know the Dao, is it bigger than you imagined.

Wang Lung had no divine sense, and he couldn't clearly grasp the temperature changes in the Dan furnace based on his physical senses alone, and when refining the spirit grass, it was easy for the spirit grass in the Dan furnace to turn into ashes due to the high temperature, or the temperature was not enough, and the spirit grass evaporated into hay.

There is not much spirit grass available in his hand, when Wang Lung first refined, he kept in mind the trick of empty explanation, first preheated the Dan furnace, when it reached a certain temperature, put in a spirit grass, and pressed the outer wall of the Dan furnace with the palm of his hand, felt the temperature change of the furnace, the temperature became high, so that the cold rouge released heat to reduce a little, the temperature was low, so that the cold rouge slowly increased the temperature, not high and low, and maintained a certain temperature range, which can not only make the spiritual grass gradually turn into powder, but also let the spiritual grass not turn into ashes due to high temperature.

Refining the spirit grass is to take its essence to remove its roughness, and refine the most valuable ingredients of the spirit grass for alchemy, if the heat is not well controlled, the spirit grass is easy to refine and fail, and the spirit grass at that time not only has no value, but is harmful to the cultivator.

According to the empty saying, to refine the amber grass, it is necessary to refine it into a yellow-green powder, and a plant of amber grass is successfully refined, and its powder is only a little.

In the Dan furnace, if the amber grass is successfully refined, only its essence part, the impurities will be incinerated at high temperature, this process is not complicated for the cultivator, when the Dan furnace is preheated and put into the spirit grass, it can be completed in ten minutes, and the success rate is very high, if you let the air to refine the amber grass, you can achieve 100% success, and you will not fail once, but unfortunately this is all for cultivators, Wang Lung is not counted.

After Wang Lung let Han Yan stop the fire, the Dan furnace had not yet been opened, and a scorched smell came into his nose, no need to look, it had already failed, in this regard, Wang Lung was not discouraged, but lowered his head and thought.

Without divine sense, he could only rely on his senses to refine the spirit grass, in fact, Wang Lung not only touched the furnace wall with his hands, but also kept smelling the spirit grass in the Dan furnace with his nose, his sense of smell was sensitive, and he could clearly smell the smell of amber grass, even if it was separated by a layer of furnace walls.

When you first put in the amber grass. Wang Lung smelled the amber herb as soon as it came into contact with the hot Dan furnace, the unique smell suddenly became very strong, and when the cold rouge raised the temperature, the smell not only did not decrease by a cent, but also became more fragrant, after the temperature was constant. The fragrance is stronger, and the unique flavor of amber grass is weakened.

I thought that I would be able to gain something from practicing for the first time, but I didn't think that it didn't take long for the fragrance to dissipate, and a scorched breath came to the surface.

After a long time, Wang Lung looked up at the two brothers, and he said his guess so that they could hear if there was a mistake.

Wang Lung thinks. After the temperature is constant, most of the essence of the amber grass has been refined, and its impurities have been stripped out, but the temperature seems to be constant, but in fact, it is a continuous heating process for the Dan furnace. It should be descending slowly, so that the amber grass in the Dan furnace has an adaptation process.

For Wang Long's understanding. The two brothers nodded in agreement, but Wang Lung didn't know how to go before it was over, and it would definitely not work if the temperature continued to drop, and then the amber grass would become a waste product, and it would be a waste product where the essence and the dross coexisted.

Wang Lung is very clear about this. He needed to test it many times to find the trick, but he didn't plan to practice again, the key was that the number of spirit grass in his hand was not enough to support his squandering, dozens of plants seemed to be a lot, but it seemed stretched thin to practice. He planned to let the air refine once, and feel the changes in the process of refining the spirit grass, which was mainly the temperature and smell of the Dan furnace.

Wang Lung asked, and Kong did not refuse, but there was a prerequisite, that is, the spirit grass refined by him, Wang Lung could not use it, Zhong Hui allowed Wang Lung to follow Kong to learn the art of alchemy, and never allowed Wang Lung to find Kong to do it for him.

This condition didn't matter to Wang Lung, he didn't expect this, and he was full of thoughts about how to feel the trick of alchemy.

After the preheating of the Dan furnace was completed, the empty did not put in the amber grass, but put in the bud of the ground, since he agreed with Wang Long's request, the three spirit grasses might as well be refined, so that Wang Lung could clearly feel the changes in them, and use this as a reference, presumably there will be some results.

Refining the Fudi sprouts is the same as the Amber Zhi grass, which is also a powder, but the essence powder of the Amber Zhi grass is yellow-green, while the Fudi Bud is gray-brown.

Wang Lung put his hand on the wall of the furnace, felt the change in the temperature of the furnace, narrowed his eyes slightly, opened his sense of smell, and carefully felt the process of refining the buds on the ground.

Ten minutes later, Wang Lung opened his eyes and asked him if he remembered, Wang Lung nodded, he had memorized the changes in the refining process of the Fudi buds, and perhaps he would feel it more deeply the next time he refined.

Seeing that Wang Lung wrote it down, he picked up the blood reed frost and put it into the Dan furnace, Wang Lung felt it attentively on the side, and at the same time remembered when to raise the temperature, when to lower the temperature, and when to keep the temperature constant.

The Blood Thread Cream was different from the previous two spirit grasses, its essence was liquid, and after being refined, it was crimson red, with a pungent taste and a slightly sour taste, and after noting down the changes one by one, Wang Lung motioned to the void to continue refining.

In the next process of refining the amber grass, Wang Lung could clearly feel some differences between the time he did it and the process of refining the air, especially in the grasp of the time of fire control, the air can often be judged in advance, and the timing is very accurate, compared with the other party, this is the main gap.

In addition, Wang Lung also knew where his mistakes appeared, to what extent the temperature had been lowered and changed again, and how the smell of amber grass had changed during the refining process.

After the completion of a series of actions, the yellow-green powder was presented in front of Wang Lung, and the air told Wang Lung that this is the amber grass that is refined well, and its smell and color can not be the slightest difference, if the color is the same, the taste is different, it means that the refining has not been successful, and it cannot be used for alchemy, if the color is different, the smell is the same.

This situation is not only for Amber Zhi Grass, but also for Voltaic Bud and Blood Worm Cream, after telling Wang Lung in the air, let him slowly comprehend, and then practice after getting acquainted with it.

After finishing speaking, he spoke at the same time, and he reminded Wang Long that there is a difference between using the cold rouge as the fire source to refine the spiritual grass and the real earth fire, after all, the cold rouge is a spiritual flame, and the earth fire resources cannot be compared with the cold rouge, and when the earth fire is refined, its changes may be a little different from this, and it cannot be refined in turn at that time.

Wang Lung nodded in thanks, sat on the side and carefully experienced the feeling just now, and it was the second day when he practiced again.

Called out by Wang Lung as a source of fire, Han Yan didn't want to give up halfway, when Wang Lung was thinking, it chatted with a brother and two on the side, and when he was asked to work, Han Yan no longer complained.

After more than ten days of speculation and testing, Wang Lung exhausted dozens of spirit grasses, although there were successes, but the number of failures was more, Wang Lung was not discouraged, as the saying goes, failure is the mother of success, after each failure, Wang Lung will think about it for a while, summarize where he made mistakes, which aspects are wrong or insufficient.

After exhausting the three spirit grasses and having also arrived near the Heavenly Spirit Star, Wang Lung asked Han Yan to return to his body and instructed him to cultivate hard.

After driving the aircraft into the Celestial Star, he found a no-man's land and landed, put down Wang Lung and left to return to outer space.

The reason why he let go of Wang Lung alone is not that the two brothers are not with him, but that he has his own affairs, if he wants to build a Dan furnace for Wang Lung, he must find a suitable fire source, Tianjing Star has many restrictions, it is not suitable for building a Dan furnace, and he can only go to other planets to see, and there is only one flying machine, and there is not too much danger in collecting spirit grass, so he is free to accompany his brother first.

The three of them met here at the latest, a month later, waved goodbye, and the two brothers flew away, and Wang Lung walked into the depths of the dense forest. (To be continued......)
