The black cauldron kept making a 'banging' iron sound under Shen Nong's percussion, this familiar sound, familiar touch, made Shen Nong recognize what material the black cauldron in front of him was made of at the first time, there is no doubt that it must be iron!

In such a primitive era, there were people who had already discovered and used iron, which couldn't help but make Shen Nong feel very surprised, you must know that the Huangqiu tribe is still at the level of civilization that uses bone products and stone tools.

Seeing Shen Nong constantly rubbing around the black cauldron, everyone couldn't help but be a little curious when they saw him like this, especially Chi and the others, they had never seen the witches in their tribe show such uncalm behavior, and it looked like a child had been exposed to something new.

"Looks like you're interested in my utensils. Luo Man walked over and said.

"Yes, where did you get this material, and is there anything left?" Shen Nong asked excitedly.

Luo Man shook his head, shook his head in a somewhat low tone and said: "There is only one left, this kind of black stone was once the product of my tribe's location, at that time we found that the material of this black stone is very hard, and it can be used to forge sharper weapons, so my people will take the time to dig out a large number of black stones in the ground, which are used to create various weapons and utensils, and we also defeated many powerful beasts with the help of weapons forged by this black stone, including pure-blooded beasts." ”

"You can even forge iron. After listening to Luo Man's words, Shen Nong couldn't help but become more interested, and said, "How did you do it?"

"With fire, my people found that when the flame burned very strongly, put the black stone in the fire and it would start to melt slowly, and finally turn into something like water, and when the flame was extinguished, the black stone would start to harden again, but then its shape changed, and we used this method to make the black stone what we wanted, and later the warriors found through the battle that the weapons made of black stone would be harder and sharper than stone and bone. Luo Man looked at the black cauldron and said lightly: "The warriors in my tribe relied on the black stone weapon to go out and hunt more than a dozen pure-blooded fierce beasts, and used their flesh and blood to train more warriors. ”

When Chi, Shaohao, and Shi Li heard Luo Man's words, they couldn't help but be secretly surprised in their hearts, and they admired the strength of the Luo Man tribe, which was more than a dozen pure-blooded fierce beasts! Compared with the current Huangqiu tribe, only one pure-blooded fierce beast was needed to commit it, and the entire Huangqiu tribe could be completely destroyed, and no one of the clansmen could survive, including Chi, who was a first-level warrior, and Xiong Yao, who was a second-level warrior.

The strength of the pure-blooded beast is really too strong, and it is very different from the mixed-blood beast, unless the tribe has a fourth-level warrior, otherwise a tribe can't resist the attack of the pure-blooded beast at all, in this primeval land, every day I don't know how many small tribes are destroyed by the mouth of the pure-blood beast.

Unlike the three of them who admired the strength of the Luo Man tribe, Shen Nong admired the Luo Man tribe even more, because according to Luo Man's description just now, it was obvious that there was a vein under the location of his tribe, and it was in this way that his tribe could obtain weapons made of iron to challenge those powerful pure-blooded beasts.

In Shen Nong's mind, the so-called pure-blooded beasts were just beasts with larger size, greater strength, thicker skin and thicker flesh, and the reason why ordinary tribes couldn't beat them was just because the weapons were too low-level to break their defenses.

It is believed that if there is also a vein in the underground of the Huangqiu tribe, then under the advanced and reasonable use of Shen Nong, it will definitely be able to exert a greater effect.

Some greedily stroked the black iron cauldron, Shen Nong couldn't help but ask, "Can you ask your tribe to trade some iron for me?" Whether it's food or salt, I'll give you a satisfactory price." ”

Luo Man glanced at Shen Nong and said, "My tribe is long gone, and I am the only surviving clansman in the tribe. ”

"That's ......" Shen Nong sighed with some regret, if he could trade iron, he would be able to forge iron axes that were more suitable for chopping wood, shovels that were more suitable for digging soil, iron pickaxes that were more suitable for digging mountains, iron hoes that helped loosen the soil, iron hammers that were convenient for smashing things, and harder iron chains that could improve efficiency.

"Wu, your tribe's strength is so strong, why did it disappear?" Shao Hao asked suspiciously.

There are very few tribes that can hunt pure-blooded beasts, and tribes like this can dominate one side, and there will be no opponents at all, so how can such a powerful tribe fall to the point where the whole clan is wiped out, and even the witch becomes a wandering witch?

Not only Shao Hao was curious, but everyone was very curious, and they all looked at Luo Man with interested eyes, hoping that he could give a detailed answer.

Maybe it's a relationship where a person has been alone here for too long and hasn't spoken to his kind for a long time, Luo Man also held back his depressed words and didn't vomit unpleasantly, so he said to Shen Nong and the others: "Let's cook something first, let's talk while eating." ”

"Good, good. Shen Nong and the others have also been busy for an afternoon because of hunting, except for eating a few pieces of jerky at noon, they have not eaten yet, after Luo Man said this, they also felt hungry, and nodded in agreement.

As the wounded, Shi Li and Chi, whose 'medicinal effect' has already been on the top, they definitely can't do the work of preparing food, and how could Shen Nong and Luo Man, who are witches, do this kind of thing in person, so in the end, the task of preparing food fell to Shao Hao alone.

He was also a cheerful person, and walked directly with a stone knife towards the carcass of a white cow that had been brought back by a white wolf hunting nearby. The taste of white beef is chewy, and after being cooked over high heat, the meat of the whole meat will be soft, which can achieve a loose effect, and the meat itself has a good taste, and the people of the Huangqiu tribe like to use white beef to cook soup.

But when Shao Hao came back with a large piece of white beef, Luo Man reached out to stop him from wanting to cook soup with white beef.

"Meat is not delicious when boiled in water, it needs to be fried to be delicious. Luo Man said in a serious tone.

"What is frying?" asked Shao Hao, Chi, and Shi Li, who had never tasted fried food, puzzled.

Shen Nong knew about frying, but the problem was that frying food needed oil, and Shen Nong had never seen such a thing as oil during the period of time when he came to the Huangqiu tribe.

I saw Luo Man take out an animal skin bag from the white wolf skin he was wearing, and then grabbed a handful of white, soft, and sticky white soft things from the animal skin bag, and in front of Shen Nong and several people, he directly threw this thing into the iron pot.

"This is?" After Shen Nong saw these things, a flash of inspiration suddenly occurred in his mind, and he hurriedly reached out and picked up a ball of soft objects and put it in his hand to check it.

"This is something that grows near the bowels and kidneys of wild beasts, and my people once found that roasting this kind of thing on a fire can make it flow out of a kind of water that can help the flame burn faster, and put the meat on this water, and the meat can be more quickly scented under the flame, and the meat and water, plus this vessel made of black stone, this is frying. Luo Man explained.

"Oh. The three of them nodded in agreement as if they didn't understand.

But Shen Nong was still observing the white soft matter in his hand, and it was obvious that what Luo Man threw into the pot was the fat in the beast's body, and the people of the Huangqiu tribe would choose not to throw it away when they handled it, because they felt that it was an impurity that could not be eaten on the beast, just like the filth in the beast's large and small intestines.

But these fats are extremely important things, as long as they are roasted on the fire, they can flow out of the oil, which is something that Shen Nong has not paid attention to and has been ignored by him. also thanks to Luo Man's prompt, after he goes back this time, the Huangqiu tribe can live an oily life.

However, the meat and fat were ready, and everyone looked at this iron pot but there was a very embarrassing situation, that is, they had no fire, fortunately, Luo Man had lived in this place for so long, and he did not rely on fruits and vegetables and raw meat to survive, I saw that he took out a stone about the size of a palm, yellow and brown intersecting, and a piece of white velvet cotton was wrapped in the head of the stone, which looked very peculiar.

"Click!"

Luo Man took the stone and rubbed it the edge of the iron pot, and suddenly the sparks between the stone and the iron pot exploded, and the splashed sparks directly ignited the wool cotton, producing a cluster of faint flames. This flame kept shaking in Luo Man's hands, setting off his whole person so mysterious and extraordinary, giving people a feeling of wanting to worship.

"Witchcraft!" the three of them shouted in surprise at the same time, and they all looked at the sudden flames on the stone in Luo Man's hand with incredible eyes, in their cognition, there was no other reason to explain this kind of thing except magical witchcraft.

But Shen Nong saw this scene in his eyes, but his face couldn't help but want to laugh, what kind of witchcraft, it's just sticking cotton to the flint, and then rubbing the flint with the iron, the characteristics of sparks will be produced between the two to ignite the cotton, a typical 'simple version of flint'.

However, this Luo Man's ability to make this kind of dexterous fire-making tool with the vision and cognition of primitive people is also very powerful, at least Shen Nong didn't have this idea in his mind before he saw this scene.

Now that everyone has a fire, frying meat is naturally not a problem, Shao Hao found a large pile of dead grass from nearby and spread it under the iron pot, and Luo Man directly lit it with the flame burning on the cotton.
