Hearing this, Guo Lao smiled, paced back and forth behind his hands, and said slowly: "Earth fire is the essence flame between heaven and earth, each kind of earth fire has been tempered for tens of thousands of years, and it contains incomparable terrifying power, and all earth fire comes from the earth realm, although it is evil, but it is also a power that people in the world are afraid of. ”

Zhou Bo didn't interject, just waiting for Guo Lao to continue to explain, only to see him gradually stop his steps and say slowly: "And this earth fire fruit is a kind of fruit derived from the eight flames attached to this earth fire, although it is not as powerful as the earth fire, but it is also the treasure of the fire attribute. ”

"What do you mean...... Did you let me eat the fruit??" Zhou Bo asked with some surprise.

Guo Lao smiled faintly, and said softly: "Before you seize the fifty percent meridians, let's dig this earth fire fruit here!!" Hearing this, Zhou Bo was really a little unhappy, he couldn't believe that he didn't learn anything here, but he wanted to dig some fruit here!

Guo Lao seemed to know the dissatisfaction in Zhou Bo's heart, only to see him slowly raise his head, staring at Zhou Bo's eyes with his eyes, and asked in a deep voice: "Zhou Bo, do you know what the most important part of alchemy is?"

Zhou Bo shook his head, from Xiuzhen to the present, except for Qingxi teaching him, he really hasn't formally studied alchemy, he only knows how to alchemy, but the most important part he doesn't know, now all his attention is focused on this strange shovel, and he is also a little perfunctory about what Guo Lao said.

Guo Lao was not angry, but said to himself: "There are two most important parts of alchemy, the first point is to refine the herbs, and the second point is to fuse them into pills. Zhou Bo came back to his senses slightly, and slowly looked away from the shovel, because his intuition told him that what Guo Lao was talking about must be something very important to him.

Seeing that Zhou Bo came back to his senses, Guo Lao smiled slightly, and then said: "Rong Dan, you already know, there is no other shortcut, it is completely dependent on strong cultivation, that is to say, as long as your cultivation is high enough and your spiritual power is enough, you can succeed in Rong Dan." ”

Zhou Bo nodded, he knew that according to his current cultivation, he could barely fuse the third-level pill, but this was far from enough, and it should be so, so he came here to cultivate, and now what made him most curious was what was the mystery of refining herbs in this first step?

Guo Lao showed an unfathomable smile at this time, and said slowly: "Actually, the most important thing in refining herbs is not how profound the cultivation is, but the purity of spiritual power!!"

"Purity??"

"That's good!" Guo Lao nodded slightly, and then explained: "And if you want to make your spiritual power more refined, the most direct way is to refine a kind of origin spiritual power!"

As soon as Zhou Bo heard this, he remembered that at the alchemy selection competition held in Tongqingshan a few days ago, many pill pharmacists were unable to successfully refine herbs, it turned out that it was because they had not refined their own origin spiritual power!! Thinking of this, he hurriedly asked, "Is the origin spiritual power still good or bad?" The implication is to know how his origin spiritual power is.

"Well, of course, the origin spiritual power is divided into good and bad, just take the fire attribute as an example, the three strongest powers are the heavenly fire, the earth fire, and the divine beast body fire. After speaking, Guo Lao said with some expectations: "You hurry up and let me see the flames!" Hearing this, Zhou Bo secretly gritted his teeth, slowly probed the situation in his body, and then laboriously gathered a trace of spiritual power on his arm, and now the spiritual power in his body is used to attach to the meridians, so it is really a challenge to let him urge out the flames.

"Peng!" An extremely subtle voice, Zhou Bo endured the burning pain in his body, his right hand urged out a subtle cyan flame, looking at the subtle flames that appeared in front of him, although the flames were not strong, but Zhou Bo's forehead was sweating slightly!

Just as Zhou Bo was busy recovering his spiritual power, he saw Guo Lao staring at him with two eyes and looking at him in shock, Zhou Bo asked suspiciously, "Guo Lao, is there something wrong??"

Asked by Zhou Bo like this, Guo Lao quickly came back to his senses, only to see a flash of surprise in his eyes, his face was slightly embarrassed, and his lips were a little pale.

"You...... You actually have the Divine Beast Body Fire?"

Guo Lao was startled at first, and then without waiting for Zhou Bo to speak, he immediately asked, "Zhou Bo, what kind of divine beast body fire have you refined?"

Zhou Bo really secretly admired Guo Lao in his heart, his flame had just been revealed, and he knew that it was the body fire of the divine beast, and it was indeed an old monster that had lived for nearly a thousand years.

Of course, Zhou Bo couldn't tell the truth, but when he saw Guo Lao's excited eyes, he quickly stabilized his nervous mood, and pretended to be surprised and said: "I used to refine this flame by chance, and I don't know what kind of divine beast body fire this is!!" After speaking, he also pretended to be excited, as if he had picked up some treasure.

Zhou Bo didn't dare to compliment his acting skills, he just begged Guo Lao Neng not to pursue it, and the facts were as he thought, Guo Lao wanted to continue to ask, but it was best to just purse his mouth, but he didn't ask again.

Seeing this, Zhou Bo really breathed a sigh of relief, thinking that if this Guo Lao really continued to ask, he would definitely show his flaws.

After a short period of shock, Guo Lao finally returned to normal after a while, at this time, he suddenly looked at Zhou Bo, and then said slowly: "Zhou Bo, although the flame you refined is the fire of the divine beast, but I felt that the flame was very weak just now, I think that the divine beast should also be seriously injured!"

Zhou Bo couldn't help but admire Guo Lao even more, just relying on a wisp of flame to analyze himself so thoroughly, it was really a god!

And just when Zhou Bo was secretly sighing, Guo Lao lowered his head and thought for a long time before he said again: "Even if you have refined the fire of the divine beast now, your spiritual power is still not pure enough! This will be the biggest obstacle restricting you from getting closer." ”

"Then what should I do??" Zhou Bo realized the seriousness of Guo's old words and asked suspiciously.

Hearing this, Guo Lao smiled faintly at the corner of his mouth, slowly walked to Zhou Bo's side, took the black shovel in his hand, and said with a smile: "I have just said, your task now is to dig the earth fire fruit and the earth fire to seize the meridians, and other things will be talked about later." ”

"You mean...... This earth fire fruit can improve the purity of spiritual power??" Zhou Bo thought for a moment and asked, he couldn't believe that the purity of this spiritual power could be improved by eating any fruit, so his tone was raised very high, and he didn't believe it very much when he heard it.

The same can be said. Guo Lao said with a hint of hesitation, but it was only fleeting, and then said: "The Earth Fire Fruit is a spiritual object between heaven and earth, and it is also the treasure of the fire attribute, of course, it can improve the purity of your spiritual power." ”

Before Zhou Bo could speak, Guo Lao continued: "And the reason why you are allowed to seize the meridians with that earth fire is also to improve the purity of your spiritual power, as for why it can be improved, you will know in the future!"

After hearing so much, Zhou Bo didn't know what to say, he originally wanted to ask Guo Lao how to use the fire fruit, but seeing that Guo Lao had no intention of explaining, he had no choice but to swallow these questions back.

In fact, Zhou Bo still had some doubts in his heart, after all, this was a year of gambling on him! If these are all as Guo Lao said, it is fine, but if there is a little deviation and mistake, then the alchemy competition in a year later will really be a failure.

As if he understood the meaning in Zhou Bo's heart, Guo Lao just sighed slightly, and didn't bother to explain, only to see him quickly walk out with a shovel.

Zhou Bo hurriedly followed, he didn't know what Guo Lao wanted to do, but as soon as he went out, Guo Lao pointed to a flat ground outside and said, "Let's start digging now." ”

In this regard, Zhou Bo had no choice but to obey Guo Lao's meaning, and took the shovel a little helplessly and began to dig according to the ground.

Soon after digging, he found that although the shovel in his hand was not good-looking, the texture was very firm, and the red soil on the ground was like chopping melons and vegetables after touching the shovel, which was very easy, and there was a heat flowing on the shovel, which made Zhou Bo feel slightly comfortable, and the spiritual power in his body trembled slightly.

Seeing that the shovel in his hand was so sharp, Zhou Bo thought that it was really worth spending 10,000 yuan to buy it, and it was really easy to use, thinking about it, he unconsciously increased the strength in his hand, and after a while, a hole appeared on the ground.

Zhou Bo now knows what is going on with the holes around here, it seems that eighty percent of them were dug by Guo Lao before, he really doesn't know how amazing the fire fruit is, it will make Guo Lao, who has always been arrogant and arrogant, give such a high evaluation, pouting, Zhou Bo didn't think about it anymore, and just continued to dig.

"Stop!!" Zhou Bo had just thrown out a big shovel of dirt, when he suddenly heard Guo Lao shouting to stop behind him, he hurriedly stopped what he was doing, and looked at him suspiciously, and found that Guo Lao didn't know when he was already standing in the cave.

Guo Lao ignored Zhou Bo, but bent down, stretched out his hands and picked them on the ground, which made Zhou Bo more surprised, thinking that he hadn't just said that this soil contained earth fire, which was very dangerous, how could he dare to touch it?

But as soon as he thought of this, he was surprised to find that there was an extra round object in Guo Lao's hand, and Zhou Bo knew that these eight achievements were the earth fire fruit, so he hurriedly got closer and looked at the round fruit carefully.

Getting closer, Zhou Bo found that the fire fruit was about the size of two fists, and its surface was covered with red and black fine lines, these fine lines were all convex outward, without any rules, but the center swung out in a circle, looking a little like a ripple feeling, and the surface of the fire fruit was also covered with a lot of sand, if you don't look carefully, it looks like a newly unearthed cultural relic.

"This is the Earth Fire Fruit??" Zhou Bo asked again uncertainly, while Guo Lao nodded lightly and said with a little excitement: "That's right!

After receiving a positive answer, Zhou Bo put his hands behind his back, hooked his head and looked at him carefully, seeing that he looked like an outsider, as if this earth fire fruit had nothing to do with him, and secretly prayed in his heart that Guo Lao could stop and stop digging any more earth fire fruits.

At this time, after Guo Lao looked at the Earth Fire Fruit for a while, he handed it to Zhou Bo with a smile, and said at the same time: "In the future, you will dig according to the appearance of this fruit!"

Zhou Bo sighed, it seems that there is really no pot to open and which pot to mention, although he is helpless, he has to take the earth fire fruit, and secretly complains in his heart, it seems that he really has to continue digging.

And when he took the earth fire fruit, his scalp suddenly went numb, and he shouted out of his mouth, so he hurriedly threw the fruit back to Guo Lao, and shouted at the same time: "What...... Why is it so hot!?"

When he took the Earth Fire Fruit just now, he obviously felt that what kind of fruit this thing was, it was a fireball at all, it was a real Earth Fire Fireball, and the heat emitted by the fruit instantly hit his whole body, making the stable situation in his body change in an instant, and it also made the earth fire attached to his meridians also ready to move, Zhou Bo couldn't stand it, so of course he threw it to Guo Lao.

Guo Lao seemed to have guessed that this would be the case, he laughed, held the Earth Fire Fruit in his hand, and smiled at Zhou Bo: "I didn't let you eat it now, you put it in the Nawu Ring first, and I won't let you eat these Earth Fire Fruits until you have seized fifty percent of the meridians!!"

When Zhou Bo heard this, he had to nod stupidly, he was afraid that the Earth Fire Fruit would burn the things in the Ice Condensation Ring, so he wanted to take out a new Na Thing Ring, which was specially used to hold the Earth Fire Fruit, at this time he suddenly thought that the Najing ring that Ji Ling Zhenren gave him had never been used, so he hurriedly turned it out, and Guo Lao saw the Na Jing ring, his eyes suddenly lit up, and asked, "Ji Ling gave it to you?" Zhou Bo nodded, Guo Lao didn't ask much, just nodded in a muffled voice, and that's it.

Seeing the earth fire fruit handed over by Guo Lao again, Zhou Bo took a deep breath, and carefully urged a trace of spiritual power into the Najing ring, and a very small white space appeared in a blink of an eye, seeing this, Zhou Bo took the earth fire fruit with lightning speed, and did not dare to have any pause to throw it into the white space, and after he finished this, he hurriedly blew his hands, as if he was afraid of burning.

"Haha......" Zhou Bo's funny action made Guo Lao laugh, only to hear him say: "Zhou Bo, you are really a tyrannical thing!!Do you know how precious this earth fire fruit is?? It is difficult for others to even see each other in their lives, but you don't know how to cherish it!!" After speaking, Guo Lao sighed heavily, and it seemed that he was quite helpless to Zhou Bo.

Zhou Bo was also speechless about this, and finally had to laugh and not explain, seeing this Guo Lao had no choice but to withdraw his laughter, he shook his head helplessly, and then he slowly walked to the side, looked at the ground for a while, then stretched out his hand on the ground and pointed indiscriminately, and said lightly: "Here and there, start digging." ”

In the evening, Zhou Bo had already dug fifteen earth fire fruits near the cave, and they were all put into the Najing ring by him, and he dug up so many earth fire fruits, he was very curious now, that is, why Guo Lao seemed to be able to see through the ground, whether it was three feet shallow or five meters deep, as long as it was where he said, there would definitely be earth fire fruits. Zhou Bo also asked him this question, and Guo Lao just replied with a smile: "As long as you calm down, you can feel the power from the Earth Fire Fruit." ”

But Zhou Bo tried many times, but he couldn't feel anything at all, and in the end, he still continued to dig the earth fire fruit in front of the coolies.

Seeing that the sky was gradually darkening, Guo Lao exhaled a little and said to Zhou Bo: "Okay, let's dig here today!"

Hearing that it was finally over, Zhou Bo sat on the ground with his ass and exhaled heavily.

He was quite embarrassed at this time, his body was full of mud and dust, like a miner, it would be a lie to say that this work is not tired, although it is much easier to dig with this shovel, but if you keep digging like this, no matter how strong your body is, you will not be able to bear it!
