"Huh......" took a long breath, and Wen Chuan, who was lying on his back, couldn't take care of the dust on the ground, and he was physically and mentally exhausted and unable to find a clean place to rest. The confrontation just now, it was really hard, without a trace of fancy, it was like two bulls with more strength, rushing straight forward until one side fell to the ground.

"Without weapons, a head-killing brute bear can exhaust people to death......" asked Chuanting and raised his head and sighed.

"If you don't have a weapon, then make a weapon!" Siyu's soft voice echoed in his mind.

"It's light, where does the copper and iron come from, you look at these reckless mountains, in addition to sedimentary rocks or sedimentary rocks, we have turned so many mountains, and we have not seen the existence of metagranulite rocks in a single place, let alone the existence of igneous rocks. There are no magnets, no surveying instruments, how can we find them?" asked Chuanting to pout, and opening his mouth was a lesson.

"Well, we don't look at the existence of the deep part, only look for open-pit mines, the main ones that have utilization value are magnetite, hematite, magnetite, ilmenite, limonite and siderite. Magnetite is good to say, the main component is ferric oxide, single crystals are often octahedredral, less diamond-shaped dodecahedron. On rhomboid-shaped dodecahedron surfaces, stripes often appear in the long diagonal direction. The aggregates are mostly dense and granular. The color is iron-black, the streaks are black, semi-metallic luster, opaque. As long as you see this, you can tell it from the crystalline form. ”

"Hematite, also known as anhydrous iron oxide ore, the main component is ferric oxide, the iron content is higher, can reach about 70%, and can be divided into many categories by the different structural conditions of its own structure, such as red hematite, mirror ironite, mica iron ore, clayey hematite, etc. Hematite has a semi-metallic luster, and the crystalline hardness is relatively high, while the earthy hematite has a very low hardness and no cleavage. Wen Chuanting paused slightly, and gently swallowed saliva.

"You also know this, if you don't know, you can check it in the database, save the waste of tongue. However, after a slight explanation, the morphology of magnetite and hematite was briefly explained, and the topic should be changed. "You see that this grizzly bear is also a waste here, it can be said that if you don't take it, you will be struck by lightning, in order not to be struck by lightning, advocate frugality, avoid waste, I will laugh at this bear paw. ”

The relieved Wen Chuanting circled around the grizzly bear carcass twice, not to mention his greed for the pair of thick bear paws, but under the pretext of wasting shame and being struck by lightning, he directly looked for stone chips, pouting where his ass was and cutting the bear paws.

"Tools!" asked Chuanting to sit on the ground with two bloody bear paws in his hands, with an expression of wanting to cry without tears, and his heart was more and more hopeful that there was a sharp knife in his hand, even if it was a small point, as long as it could play a cutting role at a critical moment.

"Come on, with the current living conditions, the primitive can't be more primitive. What else do you want for a cutting tool?!Let's find the raw ore first. Siyu jumped out again to tease and ask Chuanting's anger.

"Don't worry, there will definitely be!" said Wen Chuanting with deep resentment. "When the time comes, not only will the arrows be iron, but I will also ......"

"Cut...... Don't say you need two knives, throw one with one. ”

"Tsk, you know this?!" asked Chuanting raised his eyebrows twice.

"Of course!" As if he couldn't hear the sarcasm in Wen Chuanting's mouth at all, Si Yu replied in a rather smug tone, "However, the hardness of this bear's head can be collected and made into a witch weapon, so that you can also increase the means of attack." ”

"Not bad. Siyu's suggestion reminded him. Without saying a word, he took the small stone chip and pouted his ass to do kung fu on the bear's head.

By the time he pinned the bloody bear's head to his waist, it was already completely dark.

The dark night of the jungle is silent and dark.

This is the most dangerous time, this is the world of beasts that rise by day and night. Wen Chuanting didn't dare to risk his life, cleaned up the battlefield a little, and returned the same way with his memory, he remembered that on the way he came, there was a stone crack not far away that could accommodate him.

After a night without words, the sky was just bright, Wen Chuan stood up and found some dry firewood, and slowly roasted the processed bear paws on the fire. As for the bear's head, it had already been peeled and fleshed during the interval, leaving only a miserable white shell. The round skull has all seven orifices, and the lower part is a short bone, about ten centimeters. At this time, Wen Chuanting held the bear skull with his forehand on the neck bone, and looked at the two black eye sockets.

"What's so nice about this?" Siyu didn't understand.

"It's called research. It took a long time to answer, and the dark eyes slowly returned to normal, revealing two pupils like a whirlpool.

"Only when the research is thorough can we make targeted efforts, otherwise what we make does not meet the purpose of the production or is more likely to fail. ”

"Does the boat study understand what to do?"

"Hmm. Asked Chuanting to gently flip the two bear paws on the bonfire. "Five aggregate gods and demons!"

"Five aggregate gods and demons?"

"Yes, the Five Aggregates Gods and Demons!" asked Chuan with a smile, he could fully imagine Siyu scratching his ears and cheeks at this time.

"Sight, hearing, smell, taste and touch are the aggregates. Make this bear skull into a witchcraft that controls the five senses, with the purpose of disrupting the opponent's perception and preparing for subsequent attacks. ”

"Auxiliary Witchcraft?"

"Not bad. Now there are bows and arrows at a distance, even if there are no sharp arrows, it is still possible to deal with ordinary beasts. There are fists and feet in the near range, and when there is no sharp weapon, the beast dodges the attack of the bow and arrow, and only the fists and feet can fight when it is close. This skull must not be held as a hammer. ”

"But where did you get the refining method? I went through all the records, but I didn't find the refining method of the Five Aggregate Gods and Demons!"

"Who said no?" asked Chuanting with a smile, and asked Siyu with a rhetorical question. "In the past few years, I haven't followed Ah Gong in vain, although the old man is not very reliable, he is still a bit real. From the words that came out of the mouth of the question, how to listen to it makes people speechless. If the sacrificial elders heard about it, they would grab a broom and chase him all over the world.

"Sacrificial Elder?" Si Yu's face was full of doubts. "I didn't know that the Sacrificial Elder had taught you such a refining method. ”

"Perception, confusion, control, devouring, storage, these five formations are refined into the skull, as long as they can be organically combined, through perception and confusion formation, the opponent will be confused, weaken their perception, and then suppress or control the opponent's five senses, and through the devouring formation, the opponent's soul energy will be devoured to enhance their own power, if they are devoured too much, they can not be digested in time, and they can also be stored as reserves. Ask Chuanting to explain unhurriedly. "These five formations are all taught by the old man, do learning, can't memorize, to learn and use, draw inferences from one another, learn to practice is fundamental. ”

After waiting for a long time, I didn't wait for Siyu's soft answer, and asked Chuanting not to be embarrassed, and smiled slightly. From time to time, the hands turned the pair of bear's paws that had been charred and dropped a drop of oil, making the bonfire jump from time to time in a squeak.
