The humidity in this mountain is very heavy, and the climate is also very humid, and it is more difficult to find dry branches and dead grass than it is to wash the sand in the big waves.

Obviously, the hot weather that is about to enter the great drought has not affected the interior of the mountains in the slightest.

"Wu, the other branches and leaves are too wet, only these are dry. Shao Hao said with a blank eye.

Shen Nong looked at the little withered grass in his hand, and couldn't help but shake his head helplessly and said, "Forget it, it's better than nothing." ”

The soil in the mountains is very wet, and it is not suitable for people to burn the fire directly on the ground, so Shen Nong took a small clay pot from the board cart and put the dry grass found by Shaohao and others into the clay pot.

Under the gaze of everyone, Shen Nong directly poured the entire wooden cylinder that was burning into the pottery jar, only to see that the unknown bunch of dead grass and a large pile of black ash in the wooden cylinder poured out from the inside of the wooden cylinder, and all fell into the pottery jar.

The dead grass burning with the flames and the dead grass laid in the clay jar were intertwined, and soon they burned with each other, creating a bright flame in the clay jar, which instantly illuminated the area where everyone was.

"What a powerful witchcraft!" Huang looked at Shen Nong in great surprise, and from his stunned expression, Shen Nong could feel how shocked this guy was at the moment.

And the other Huangqiu people were not much better than Huang, only Chi's expression was a little calmer, after all, he had been with Shen Nong for the longest time, and it was not strange to see too many things.

Shen Nong shook the wooden cylinder in his hand, shook off the remaining black ash inside, and then put it back into his animal skin bag.

Only he knew that he was not using sorcery, but a minimum version of the fire fold.

The fire fold is a very portable and efficient fire tool, which is much more convenient than drilling wood for fire, and does not need to waste too much time when using it.

But for the production of genuine fire folds, the current Shen Nong is powerless, because flammable materials such as nitrate and sulfur are the key materials for making fire folds, but these materials are legendary for the Huangqiu tribe, and no one in the entire tribe has ever seen these things.

So Shen Nong can only choose to settle for the next best thing to make a one-time fire fold, its practical fire fold is not very appropriate to call this thing made by Shen Nong, if you have to take a name, Shen Nong prefers to call it a portable fire source.

The method of making a portable fire source is very simple, first of all, five dried grass roots are wound together with each other, twisted into a bunch, and this bundle of grass roots is placed on the flame to bake, making it a 'wick' with no moisture on the body.

At this time, the bark is ground into powder, stirred into a glue liquid with some water, evenly spread on the 'wick', and then exposed to the sun until it dries, so that you can get a burning object similar to the incense used in worshipping the Buddha.

As we all know, the burning speed of incense is much slower than that of candles and torches, and if it can be stored in a space with slow air circulation, the burning speed of incense will undoubtedly become more sluggish, so as to achieve a good fire preservation function, so the wooden tube covered with a lid is such a space with slow air circulation.

Speaking of fire preservation, we have to mention the black ash that Shen Nong poured out of the wooden tube, these black ashes are not ordinary black ashes, but grass clippings left over from the burning of plants and trees.

This grass clippings are lighter than fine sand, and even if they cover the fire, it will not hide the fire until it is extinguished, but will curb the burning rate of the fire, so that the fire will burn for a long time.

Under the double protection of the incense-like 'wick' and the grass clippings, the flame in the wooden tube can continue to burn secretly for at least two days.

The reason why this portable fire source was made was because Shen Nong was worried that on the way to the Ten Parts Conference, everyone would encounter a situation where they would have to spend the night in the wild, if this kind of thing really happened, wouldn't it be very embarrassing to have no fire, so Shen Nong made such a thing just in case, but he didn't expect it to really come in handy in the end.

With the flames, everyone can be considered relieved to spend the night in this mountain, but it is only a few, you must know that the most dangerous thing in the forest at night is not the darkness, but those beasts and fierce beasts hiding in the dark, you may meet the attack from any direction at any time, so everyone must be vigilant.

As the fire in the pottery jar is getting bigger and bigger, Shen Nong gradually dares to throw some damp branches into it to help burn, and the sound of wooden branches such as 'popping' is constantly sounding in the pottery jar, and from time to time there will be sporadic fire points splashing out from the pottery jar, bringing a strong warmth to people.

After nightfall, the inside of the mountain cooled down very quickly, if it weren't for the pile of flames in front of them, I am afraid that Shen Nong and the others would be frozen and shivering now.

Rao was like this, but Shen Nong still felt a little cool on his body, so he took the initiative to lean towards a white wolf next to him, buried his body in the thick white hair of the white wolf, and enjoyed the warmth brought by the wolf blanket.

Others don't have such a good treatment as Shen Nong, these three white wolves only obey Shen Nong, who has a bone whistle, when they see someone other than Shen Nong approaching, they will immediately show their sharp teeth and hideous expressions, and warn each other in this way.

Just as Chi and Shao Hao got up and were about to go to the cart to get some food and come over for a barbecue, a strange roar suddenly sounded in the depths of the forest in the north.

This voice didn't seem to be too far from the location of themselves and the others, so the two of them quickly dispelled the idea of wanting to barbecue, and instead reached out to pick up their bone spear from the cart, staring very vigilantly at the direction from which the strange roar came.

"Shhh...... Woo...... "Under the gaze of everyone, it didn't take long for a black shadow to finally appear in the darkness in that direction, and this black shadow slowly walked towards the location of Shen Nong and the others, and I don't know if it was attracted by the bright firelight, or tempted by Shen Nong's food.

Under the illumination of the firelight, Shen Nong and the others finally saw the true face of this black shadow, it turned out to be an An Clan Beast!

It is extraordinarily large, with a long body, but short limbs, a long tail, hoof-shaped soles, an extremely long face, and broad and swollen cheekbones, which looks like a hyena with the body of a lion and the head of a bear.

Shen Nong has been in the Huangqiu tribe for so long, and it is the first time he has seen the living An Clan's middle beast, and he can't help but widen his eyes with great excitement, for fear of seeing some picture.
