Wang Lung and a brother stood respectfully at the bottom, the whole hall was quiet and a little weird, no one spoke, Zhong Hui sat at the top, looked down at a silk book in his hand, and ignored the three of them, this situation has been half an hour.

Half an hour ago, Wang Lung and his party finally returned to the earth, and after seeing Zhong Hui again, they listened to the other party's departure with a slight salute, but Zhong Hui behaved a little strangely, even if Wang Lung and others saluted him, he didn't say anything, his eyes kept staring at the silk book in his hand, which made Wang Lung very depressed, but the two brothers warned him that he must calm down.

Finally, Zhong Hui closed the silk book in his hand, raised his eyes to look at the three people below, nodded slightly, and said slowly: "I didn't expect you to go to collect the three elixirs, it took so long, do you know that the next time is not enough." ”

Not enough, Wang Lung couldn't wait to point at Zhong Hui's nose and scold, knowing that his time was running out, but it took more than half an hour to live, Wang Lung couldn't be angry about it, he thought like this in his heart, but he couldn't say it on his lips.

"There was a little bit of an episode on the way, so it was delayed for a long time. Wang Lung said a little respectfully.

Zhong Hui nodded and said: "I don't care what situation you encounter, but I made it very clear to you at the beginning, within a year, hand over a pill of Peiyuan Dan, even if you pass, if not, don't blame me for not being merciful." ”

Wang Lung said: "The juniors naturally know, please rest assured that no matter whether it is successful or not, I will try my best to complete it." ”

Zhong Hui said, "Okay, since you've collected enough elixir, then you can go to alchemy." Speaking of this, Zhong Hui took out a white jade plaque with his backhand, threw it to one casually, and continued: "You two brothers take him to the Earth Fire Room. Tell him what's at stake, and come back to me later. ”

He bowed and said yes, and led Wang Lung to the room next to him, and he accompanied him, and after entering that room, Wang Lung did not see any earth fire. Instead, it was a bedroom, which made Wang Lung very puzzled.

"What you see is not necessarily true, it's all an illusion, you see. As soon as he spoke, he threw the jade card in his hand, muttered two words in his mouth, and a law decision came out of his hand, only to see the jade card flash fluorescently, and then it returned to its original appearance.

Look at the whole room. The so-called bedroom had disappeared, and a simple teleportation array appeared in front of everyone.

"Teleportation Array......?

Without waiting for Wang Lung to finish speaking, he spoke first: "I'll talk about it later, let's go over first." ”

Wang Lung nodded blankly, and stepped on the teleportation array with him, and with a hand of magic duel, the teleportation array opened in a soft sound, and Wang Lung didn't understand what was going on. It felt like a flower in front of him, when he saw his surroundings clearly. It's gone somewhere else.

Streams of scorching air came from the surface, even if Wang Lung's body was strong enough, it made him feel a slight burning pain in his skin, but this feeling came and went quickly, and before he reached the earth's fire, the air alone had already exceeded the high temperature of thousands of degrees. Even if an ordinary person stands here, their bodies will spontaneously combust.

"Come with me. Ignoring Wang Lung's reaction, he said a faint word and walked towards a stone cave in front of him.

The place where Wang Lung and the others teleported was not large, and the teleportation array under their feet was in a corner, and the opposite side of the teleportation array was the stone cave they were about to enter. It is said to be a stone cave, but the stone wall is made of crimson rock, this kind of stone king rex has never been seen, under the touch of the hand, there is no such hot feeling, but the temperature is lower than the air.

After entering the stone cave, not long after the three of them left, a spacious room appeared in front of everyone, the room had deep human traces, the four walls were cut very flat, carved with some unknown symbols and imprints, a stone bed on the right side, there was no futon or anything like bedding on it, only a futon with a faint white light, and directly opposite the stone bed, there was a small countertop, and there were six strange beast heads around the countertop, all facing the middle of the countertop, and in the middle of the countertop, there was a miniature prohibition.

Other than that, there was nothing else in the room, and after Wang Lung entered it, he looked around, but he didn't see where the so-called earth fire was, and the temperature in this room was obviously different from other places, which gave him a very cool feeling.

Finally, Wang Lung fell on the small countertop, glanced at it slightly, turned his head and asked, "If I'm not mistaken, that countertop can go straight to the fire." ”

He nodded and said: "Yes, the earth fire mouth is covered by that formation, you can use this jade plate to open it, as for those six beast heads, they also have their uses, when you need to increase or decrease the strength of the earth fire, you can open and close them one by one, but you can't use it this time, refining Pei Yuan Dan, just use that one earth fire mouth." ”

Wang Lung nodded and asked, "I was going to ask you just now, why did you stop me, and you are still mysterious, what is going on?"

He chuckled lightly and said, "Do you want to ask Zhonghui seniors here, there is obviously only one teleportation array in that room, what are you doing with a phantom array, do you think Zhonghui seniors are doing this too much?"

Wang Lung nodded and said, "Yes, he is alone, why is he so mysterious, are you still afraid that someone will lurk in?"

He shook his head and said, "Xiaolong, some things are not as simple as you think, the room where the teleportation array is located, in addition to the phantom array, there is also an isolation prohibition, do you remember the deep pool where we came down from the Ice Palace?" Seeing Wang Lung nodding, Yi continued: " Located in the North Pole, what is the water temperature of the deep pool of the Ice Palace, you know it yourself, if there is no prohibition and blocking, let alone the Ice Palace, I am afraid that the Arctic iceberg will be gone, this is a place where the fire is, and the temperature emitted by it is much stronger than those volcanoes and the like, if you don't use the ban to isolate it, you can think about the consequences yourself. ”

Wang Lung said: "Yes, although I have not seen the temperature of the earth fire, but just now outside the stone cave, the air temperature alone is not less than 1,000 degrees, if it is not isolated, the North Pole will not exist, maybe it will become a sea of fire." ”

"Not only that, although the prohibition arranged by Zhong Hui's predecessors is powerful, but any prohibition cannot be perfect, even so, there are still a small number of earth fires that cannot be controlled, and the temperature that overflows makes the waterhole unique." Moreover, there is earth fire in the Arctic, and although it is properly controlled, the glaciers in the Arctic are still melting little by little. ”

One said: "Okay, this matter is not something we can control, Senior Zhonghui is stationed here." The real purpose is to take care of the earth fire and prevent it from harming the earth, and then let Xiaokong tell you about alchemy. ”

Hearing this, Wang Lung turned his gaze to Kong, and Kong nodded his jaw and said slowly: "You are not a cultivator, some experience is not easy to say, I will give you some suggestions, you can grasp it yourself, as for whether you can succeed." It's up to you. ”

An hour later, the two brothers left the cave, and Wang Lung was the only one left here, and the jade plate in his hand was in Wang Lung's hand at this time.

Before leaving, he told Wang Lung that after they left, the prohibition would be reopened, and Wang Lung would be in a completely closed state here. No one will come to disturb him, wait for Wang Long's alchemy to end. You can open the ban with a jade card.

In addition, the jade card also has a very important role, that is, to open the earth fire, Wang Lung is not a quasi-cultivator, and he cannot use spiritual power to open the earth fire prohibition by himself, and can only be completed through the jade card.

Wang Lung sat cross-legged near the table. He looked at the prohibition in the middle of the table, and thought about the suggestion that Sora had just said.

Likong told Wang Lung not to rush the alchemy first, familiarize yourself with the refining of the spirit grass, and familiarize yourself with the temperature change of the earth fire is the most important. Wang Lung has no divine sense, and Wang Lung can't see the changes inside the Dan furnace, he can only feel it with his hands, and this feeling on his skin is thousands of miles different from his divine sense, which is a challenge for Wang Long.

Wang Lung had once refined the spirit grass, but it was just for practice, and the amount of refining was not much, and now that more than half a year had passed, the familiar feeling had almost been forgotten.

There is not much time left for Wang Lung, and he suggested that Wang Lung should not refine the spirit grass for more than two months, and leave a month for alchemy, no matter how much spirit grass is refined, there must be at least one month to alchemy, because alchemy is very important to Wang Lung, he has no experience, and the chance of success is minimal, and refining a furnace of pills, as little as one day, more than three days, according to empty calculations, Wang Long refining a furnace of Pei Yuan Dan, it takes about three days, the reason why it will take three days, the key is that Wang Lung can not control the temperature of the earth fire very accurately, what others can do at one time, maybe Wang Lung will take several times。

Adjusting his mentality, Wang Lung closed his eyes and meditated for a moment, then opened his eyes and took out a bunch of materials from the storage spirit vessel with his backhand, the pile of materials was placed casually beside him, if anyone was present, he would definitely find that these materials were all the same kind, and the number was very amazing.

This is exactly the blood rex frost that Wang Lung collected, when he was on the Heavenly Spirit Star, the number of blood recew frost harvested was extremely large, there were hundreds of thousands of plants, refining Pei Yuan Dan did not need too much blood rex frost, since the sky let him be familiar with the refining of the spirit grass first, then use the blood rex frost as a material for training, anyway, the number of large quantities cannot be used up, even if all the refining fails, he will not feel distressed.

The jade plate in his hand was put on the countertop prohibition, only to see the forbidden fluorescence flowing, and in a moment those talismans emitted a dazzling light, and in the blink of an eye, there was a bowl-sized gap in the middle of the countertop, and a hot air flow came to the surface.

Wang Lung let out a sigh of relief, this prohibition had just been opened, and the residual temperature of the earth fire was already as high as thousands of degrees, fortunately he had rough skin and thick flesh, otherwise let alone alchemy, even if he stood here, it would be difficult.

As soon as the ban was removed, Wang Lung hurriedly took out a Dan furnace that he had helped build, and threw it casually, and the Dan furnace stopped above the ground fire mouth, suspended steadily in mid-air, and just finished this action, Wang Lung saw that there was already a fire snake coming out of the earth fire mouth, and the flames slowly rose, and when the bottom of the Dan furnace was completely wrapped, it just stopped the upward trend.

Wang Lung stretched out his hand and stuck it on the Dan furnace, feeling the temperature change of the furnace, it was only a few breaths, and the temperature of the Dan furnace had reached a very high point, almost the same as the temperature of the earth fire, but Wang Lung did not immediately remove his hand, but continued to put it on the Dan furnace, and carefully felt the temperature change of the earth fire.

After about half an hour, Wang Lung moved his hand away from the Dan furnace, at this time he already knew in his heart the law of the temperature change of the ground fire, this law is actually very periodic, when it reaches a constant temperature, the earth fire will automatically decrease some, when it drops by about ten degrees, the temperature of the earth fire will gradually rise, on the curve of constant temperature, the temperature difference is about 20 degrees, this temperature difference seems not small, but compared to the high temperature of tens of thousands of degrees of earth fire, it can be ignored.

For the earth fire, the temperature difference of twenty degrees is negligible, but this is not the case for Wang Lung, even if it is one degree different, it is possible to make the materials in the Dan furnace scrap, so Wang Lung must use the jade plate in his hand to control the change in the size of the earth fire, and it is best to maintain it at a constant temperature.

Looking at the somewhat red palm, Wang Lung shook his head helplessly and smiled bitterly, this way of refining the spirit grass looks quite easy, the actual situation is only known by Wang Lung himself, the distance between the body and the earth fire is only about twenty centimeters, and the high temperature of tens of thousands of degrees is already the limit that Wang Lung can bear, if the grade of the earth fire here is increased a little more, let alone alchemy, I am afraid that Wang Lung will not even be able to stand here.

Readjust the mentality, lift the top cover of the Dan furnace with his left hand, grab a blood tex frost with his right hand, and throw it directly into the Dan furnace without looking at it, when the top cover is put down again, Wang Lung's left hand will stick to the Dan furnace to experience the change in temperature, and the jade plate in his right hand is only a few centimeters away from the ban.

Now the temperature in the Dan furnace is still constant, basically there is no change, and Wang Lung's right hand will not make any movements, but this situation did not last long, the left hand pressed on the Dan furnace trembled slightly, and the jade plate in Wang Lung's right hand has been pasted to the prohibition.

Soon, a scorched smell came out of the Dan furnace, Wang Lung shook his head, temporarily put away the jade plate, opened the top cover of the Dan furnace with his left hand, and fished it out into the Dan furnace with his right hand, and a handful of black things appeared in the palm of his hand, and the first blood reelwood frost was scrapped.
