Being waved in front of him by the old man, Zhou Ran reacted, his vision gradually became clear from the sloppy just now, and glanced at the old man in front of him, Zhou Ran nodded, if the old man went to explore the world of wind, it didn't matter, after all, the old man's current comprehensive strength on the panel was still only Hong level, one person only occupied the position of 5 units, even if he himself was replaced by 5 wild stone spearmen, the efficiency of exploration was estimated to be hundreds of times worse than that of the old man, And the explosion rate of the props in the 7th layer world is definitely higher than that of the 9th layer, this time the viper just entered the 9th layer to explore, and obtained so many good things, especially the kind of gold that can strengthen the metal.

Zhou Ran asked the old man to take a closer look, the old man gave Zhou Ran a vague answer after looking at the gold, he couldn't be sure before the experiment, but it does contain some very special materials, if it is added to his own medicine furnace, maybe it can be refined with other metals, a Wai Dan with more powerful attributes than the one he used, and then with these special gold nuggets that can strengthen the effect of metal, The old man and Zhou Ran's initial thoughts also changed slightly, and at the beginning, the two of them's most priority option was the fire attribute demon pill.

It is a relatively simple thing to use the demon pill to refine the outer dan, plus the fire attribute itself is a relatively common attribute, and Zhou Ran has learned the fire spell, if you want to depict the spell upwards, and if you want to carve it with other charms, it will be very simple, it even tried to imagine it, can you figure out the refining process on the fire gourd, if you can get it, you can draw a scoop according to the gourd to this fire attribute Wai Dan to do the same, If you can store fire crystals in this fire attribute outer pill, then over time, the power it can exert may be stronger than the fire gourd, and among all the attribute demon pills, the fire attribute demon pill is also one of the most suitable demon pills for refining outer pills, mainly because the fire attribute has the possibility of naturally reducing impurities, and the total energy intensity is exactly the same, compared with the energy intensity of the fire attribute outer pill after the final successful refining, the demon pill of other attributes is slightly higher.

It's just that the two of them thought it was good at the time, but after having the gold nuggets, the two of them suddenly felt that it should be good to use the material method to refine the outer dan, and the main reason why they hadn't considered this method before was because after the use of these metals was completed, the greatest probability of the appearance of the outer pill was the lower grade outer dan, and even if you want to maintain the level of the lower grade, it is more difficult, and you need to consume more than twice the material, but some of the gold nuggets are different, and it is appropriate to consume a little more material, Coupled with the gold nuggets, the old man did not say that he was thirty percent sure that the Wai Dan he had refined could be promoted to the middle grade, which was already quite powerful, you must know that when he was refining the Wai Dan before, if there was no assistance from the Wind Orb, according to his own words, the probability of being able to refine the middle grade was only about 5%.

The two later discussed this matter again, and finally decided to try to refine it with the material method first, but there was a disagreement about which material to use, Zhou Ran felt that he should first use a large number of metals in his territory to try to refine, after all, the level of these metals opened from the treasure chest is not low, and the high level of some of the materials is higher than the level of the wind world and the materials it obtained in the Heavenly Demon Fantasy Realm, and the old man's idea is to refine another wind attribute Waidan, After all, the wind attribute itself can be obtained from the world of wind, no matter what kind of upgrade materials are needed in the future, the difficulty of obtaining them will definitely be lower.

This time the old man chose to enter the world of wind, not for this reason, he just wanted to enter the world of wind, to see if he could find some materials to help him upgrade the outer pill and strengthen the outer pill, no matter how bad it was, he could properly obtain some materials, after all, he was very fond of those gold nuggets now, but those gold nuggets looked like they were carrying five or six backpacks full of them, which may weigh one or two hundred kilograms in total, but if they are really refined, it is estimated that they will not be used too many times. After all, this kind of gold nugget can be regarded as an auxiliary material.

Zhou Ran thought about it and didn't hesitate too much, so he nodded and agreed, the number of pills stored in the old man's room now is not small, and the total number of pills for various healing and auxiliary types may be thousands, and as for the most basic healing medicine, it is even estimated that 3,000 copies are saved, of course, the 3,000 copies here refer to each person using it once at a time, and this time it can probably heal minor injuries to moderate injuries, more serious injuries, You have to use multiple medicines or higher-quality pills, but even so, even if you encounter the situation of the heavenly gods before, these stored medicines can also guarantee that you can be cured two or three times, so Zhou Ran has no idea of forcibly leaving the old man behind.

Even if he wants to leave the old man behind now, it's useless, after all, the medicinal materials that can be refined in the territory now, there are not even many left, most of them are some auxiliary types of medicinal materials, the real main medicine has basically been refined by the old man, I have to say that the old man is really powerful, although Zhou Ran feels that he nests in the woodworking workshop every day, 18 hours of the 24 hours are used to try to study, or to cultivate, and the remaining 6 hours include eating, sleeping and leisure, But even this is incomparable with the old man, who can compress the 6 hours into three hours.

Of course, it is mainly because its internal qi cultivation is stronger than Zhou Ran, if Zhou Ran refers to the total reserve of internal qi, it is indeed not much worse than the old man, but the quality is still so bad, not to mention the strength of the meridians, in this case, the effect of the two people on the internal qi of the same attribute is not at the same level at all.

And for this problem, the old man does not have a very good way, if you want to strengthen the meridians in your body, the best way is to warm up for a long time, if you have unlimited time, even if it is to cultivate the most basic qi absorption technique, cultivate for 10,000 years, it is estimated that you can also warm the meridians like a vast river, Zhou Ran's current cultivation of internal qi is only a few months, and it is already very outrageous to be able to achieve this strength.

Of course, this is also the reason why Zhou Ran has not deliberately cultivated internal qi for a period of time, and now he can obtain very little reinforcement by deliberately cultivating internal qi, so it is better to find a way to strengthen the combat effectiveness of the soldiers under his command.
