Reluctantly pinched out the shape of a stove, Zhou Ran used a bamboo tube to form a whole bucket of river water, and then began to slowly pour it along the edge of the outer ring of the stove, and in the process of pouring down, he also stretched out his hand covered with mud, and gently patted the outer ring of the mud bamboo to ensure that its shape did not change, and at the same time made it a little tighter.

After the shape was done, he took out the clay bricks he had made during this time, this kind of clay bricks, Zhou Ran used simple clay, and then fired it a little, it was not even a qualified brick, but it was enough to barely use it for emergencies. At least he didn't plan to use this rough furnace for a very long time, as long as it was enough to make sure that the furnace could withstand hundreds of degrees of heat and successfully smelt a few liquid bronzes.

After circling the bricks in this furnace, circling to the commanding height, then stuffing the cracks with soil, patting it, and waiting for the furnace to dry During the period of air drying, Zhou Ran went to the old man to study the pharmacology for a while.

He found that although the old man did not teach the skills of medicine and pharmacology, but just listening to him, Zhou Ran was also able to remember a lot of useful things, after all, after this period of training, his spiritual attributes have become higher and higher, although there is no way to intuitively connect with wisdom and wisdom, but if the spiritual attributes are improved very obviously, then the memory ability and comprehension ability have been improved.

To put it simply, the improvement of mental attributes can improve intelligence or IQ, but there is no way to improve wisdom, wisdom refers to the degree of use of intelligence and IQ, there are quite a lot of works, a character will be shaped into a high intelligence or high IQ character, but he is faced with a lot of things later, showing a very stupid side, which proves that he simply has a strong enough brain, but did not use the wisdom of this powerful brain.

Zhou Ran is the same now, his wisdom is only the level of ordinary people, but his intelligence level has indeed increased significantly with the improvement of his spiritual attributes, at least the old man has been able to read to him every day during this time, he can memorize 60%~70% of it, all by rote.

In his spare time, when he was in a daze, he thought about it slowly, and this method also did not enable him to acquire the ability of pharmacology or medicine, but it could make him like the old man, who did not master this ability, but was able to use this ability, just like his previous carpentry skills.

And this kind of behavior is actually very beneficial, Zhou Ran's carpentry ability after entering the basic level, it only took 10 hours of honing to improve the mastery level.

It's not because of his behavior of brushing experience, brushing experience is indeed able to quickly improve the level of skills, but it is impossible to improve so quickly, mainly because Zhou Ran has the experience of his previous life in his mind.

And the same is true of pharmacology and medical skills, he has mastered these things now, even if he has not yet mastered this corresponding ability, but if he masters the corresponding ability later, then the ability will soar to an extreme at a very fast speed.

After listening to a lot of things on the old man's side, when he heard that he had a splitting headache and felt that his mind was full of relevant knowledge, he went back to the woodworking workshop in a circle, made some small hand ornaments or made some gadgets out of some metal, and barely exercised his handicraft ability.

By the way, it should be mentioned here that the metal opened from the treasure chest is roughly divided into three situations, the first is the most common metal ingot, which is usually about the same size as a palm, with a height of about 3 cm ~ 5 cm, which is the most common style.

Sometimes, if the amount of metal is set to be large, it will be put into some chests, and the blacksmiths of the Beacon Age usually use this method to preserve the metal.

The second case is metal particles, which usually correspond to relatively rare metals, but sometimes when the white light material is extracted from the treasure chest, the amount of metal that appears is too small, although the level is low, but it will also appear in the form of metal particles, which are basically the size of a thumb, and are usually packed into a cloth bag or box.

The third is the largest metal square, the minimum volume of this metal square is also a cube with a side length of 10 decimeters, the first and third Zhou Ran have no way to build it now, the volume of this thing is too big, if he wants to successfully forge it, he has to wait for his furnace made by the soil method, and then melt these metals into a liquid before it can be used, but the metal particles are different.

He found some stone bowls in his miscellaneous items that were opened from the treasure chest, the thermal insulation effect of these stone bowls was barely good, Zhou Ran converted his internal qi into a bias towards flames, usually he would transform into a higher temperature red lotus or incinerate it, and then put a dozen metal particles into these stone bowls, and then use the internal qi to directly melt them into liquid.

Although this kind of behavior can be fired into a liquid state, but in fact it is very difficult, don't look at Zhou Ran to do it so easily, it is estimated that only he and the old man can do it in the entire territory, this kind of behavior of directly using internal qi to transform into a certain corresponding attribute and then release it can be regarded as a very luxurious means of application.

Even if Zhou Ran's current internal qi reserves, at most, he would heat two bowls of metal particles into a liquid state, and then he would consume all the internal qi in the light body, but these metals were enough, so he fired more than a dozen bowls of liquid metal in about three days, and then used these liquid metals to make a lot of useful gadgets.

The main thing is to create some metal skins and metal plates, which are used to wrap the edges of the chariot and strengthen the main body of the chariot, and the rest is forged into some small jewelry and armor, and in the case of armor, he is mainly forged into heart goggles and neck rings.

Needless to say, the use of the heart goggles may not sound like a common thing, but it was still very useful in the primordial era, and this thing was not to protect against primitive people, but to defend against wild beasts.

You know, the collars worn around the necks of those hounds usually have spike-like ornaments, not only for the sake of beauty, but more importantly to prevent the sneak attack of certain wild beasts.

Most of these beasts that survive in the wild will have a very vicious trick, that is, sneak around the back, and then bite the neck of the creature, because they know that this method can inflict a killing blow on most creatures, and the neck ring was born to prevent such a situation.

Zhou Ran used these molten metals to forge 6 neck rings, just one for each of them, but his current handicraft ability is still very low, so the level of the forged neck rings is not high.
